Answer:
B) x + 1/y times h/g+1
Step-by-step explanation:
We need to divide [tex]\frac{x+1}{y}[/tex] by [tex]\frac{g+1}{h}[/tex] then match with given choices to find the correct equivalent result.
where given choices are:
A) x/y times h/g
B) x + 1/y times h/g+1
C) x+ 1/y divided h/g+1
D) y/x+1 divided g+1/h
So let's divide [tex]\frac{x+1}{y}[/tex] by [tex]\frac{g+1}{h}[/tex]
[tex]\frac{\left(\frac{x+1}{y}\right)}{\left(\frac{g+1}{h}\right)}[/tex]
we are allowed to flip the bottom fraction and change division sign into multiplication. So we get:
[tex]=\left(\frac{x+1}{y}\right)\cdot\left(\frac{h}{g+1}\right)[/tex]
Hence correct choice is: B) x + 1/y times h/g+1
Let's start by simplifying the given expression step-by-step:
\[ \text{Given Expression:} \quad \frac{x + \frac{1}{y}}{g + \frac{1}{h}} \]
Firstly, we will find a common denominator for the numerator and denominator of the given fraction.
For the numerator, we already have a single term x and a fraction \( \frac{1}{y} \), which can be combined without altering the denominator.
For the denominator, we have term g and a fraction \( \frac{1}{h} \). To combine these, we need to multiply both terms by h to get a common denominator.
So, the expression becomes:
\[ \frac{x + \frac{1}{y}}{g + \frac{1}{h}} = \frac{xy + 1}{y} \cdot \frac{h}{gh + 1} \]
Next, we will multiply the separated fractions across the numerator and the denominator:
\[ \frac{xy + 1}{y} \cdot \frac{h}{gh + 1} = \frac{(xy + 1) \cdot h}{y \cdot (gh + 1)} \]
Now, let's consider the given options and check which one is equivalent to our simplified expression:
Option A) \( \frac{x}{y} \times \frac{h}{g} \)
This option simplifies to \( \frac{xh}{yg} \), which is not equivalent to the expression we have because we have \( xy + 1 \) in the numerator, not just \( xh \).
Option B) \( (x + \frac{1}{y}) \times \frac{h}{g+1} \)
For this option, if we simplify, we do not obtain a single fraction with the term \( xy + 1 \) in the numerator and \( y(gh + 1) \) in the denominator, instead, this option gives us \( xh + \frac{h}{y(g+1)} \), which is different from our simplified expression.
Option C) \( \frac{x + \frac{1}{y}}{h/(g + 1)} \)
To simplify this option, we take the reciprocal of the denominator and multiply it with the numerator:
\[ \frac{x + \frac{1}{y}}{h/(g + 1)} = (x + \frac{1}{y}) \times \frac{g + 1}{h} \]
\[ = \frac{(x + \frac{1}{y})(g + 1)}{h} \]
\[ = \frac{xg + x + \frac{g}{y} + \frac{1}{y}}{h} \]
\[ = \frac{xg + x + \frac{g + 1}{y}}{h} \]
This is not equivalent to our simplified expression either because it involves terms like \( xg \) and \( x \), which do not appear in our expression and does not fit the form \( \frac{(xy + 1) \cdot h}{y \cdot (gh + 1)} \).
Option D) \( \frac{y/(x+1)}{g + \frac{1}{h}} \)
To simplify this option, we multiply by the reciprocal of the denominator:
\[ \frac{y/(x+1)}{g + \frac{1}{h}} = \frac{y}{x+1} \times \frac{h}{gh + 1} \]
\[ = \frac{yh}{(x+1)(gh + 1)} \]
Again, this is not equivalent to our simplified expression, since the expressions \( y/(x+1) \) and \( (xy + 1)/y \) are different.
None of the options (A, B, C, or D) match the simplified form:
\[ \frac{(xy + 1) \cdot h}{y \cdot (gh + 1)} \]
Therefore, none of the given options are equivalent to the original expression \( \frac{x + \frac{1}{y}}{g + \frac{1}{h}} \).

2. What is the center and the radius of a circle given by the equation
x2 + y2 + 4x - 10y + 20 = 0?
A.(-2,5) and r=square root of 25
B.(2,-5) and r=square root of 20
C.(-2,5) and r=3
D.(2,-5) and r=3
Answer:
C
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given x² + y² + 4x - 10y + 20 = 0
Collect x and y terms and subtract 20 from both sides. that is
x² + 4x + y² - 10y = - 20
To obtain standard form use the method of completing the square
add ( half the coefficient of the x/y term )² to both sides
x² + 2(2)x + 4 + y² + 2(- 5)y + 25 = - 20 + 4 + 25
(x + 2)² + (y - 5)² = 9 ← in standard form
with centre = (- 2, 5) and r = [tex]\sqrt{9}[/tex] = 3 → C
By rearranging the given equation to match the standard form of circle equation, we can determine the center of the circle to be (-2,5), and the radius to be 3.
Explanation:The equation provided can be rewritten in the form (x - h)² + (y - k)² = r², wherein (h, k) denote the center coordinates of the circle, and r is the radius. To arrange it in this form, we group terms to complete the square for both x and y:
x² + 4x + y² - 10y = -20
⇒ (x² + 4x + 4) -4 + (y² - 10y + 25) - 25 = -20
⇒ (x + 2)² + (y - 5)² = 9
With this, we can identify the center of the circle to be at point (-2,5), and the radius is the square root of 9 which equals to 3. Hence, the correct answer is option C.

Find the rectangular coordinates of the point (squareroot3, pi/6)
Answer:
The rectangular coordinates of the point are (3/2 , √3/2)
Step-by-step explanation:
* Lets study how to change from polar form to rectangular coordinates
- To convert from polar form (r , Ф) to rectangular coordinates (x , y)
use these rules
# x = r cos Ф
# y = r sin Ф
* Now lets solve the problem
∵ The point in the rectangular coordinates is (√3 , π/6)
∴ r = √3 and Ф = π/6
- Lets find the x-coordinates
∵ x = r cos Ф
∵ r = √3
∵ Ф = π/6
∴ x = √3 cos π/6
∵ cos π/6 = √3/2
∴ x = √3 (√3/2) = 3/2
* The x-coordinate of the point is 3/2
- Lets find the y-coordinates
∵ y = r sin Ф
∵ r = √3
∵ Ф = π/6
∴ y = √3 sin π/6
∵ sin π/6 = 1/2
∴ y = √3 (1/2) = √3/2
* The y-coordinate of the point is √3/2
∴ The rectangular coordinates of the point are (3/2 , √3/2)

Consider the functions.
f(x)= square root x
g(x)= square root x-3+1
h(x)= square root x+1-2
Which statement compares the relative locations of the minimums of the functions?
1.The minimums of g(x) and h(x) are both in the first quadrant.
2.The minimums of g(x) and h(x) are both in the third quadrant.
3.The minimum of h(x) is farther right and up from the minimums of f(x) and g(x).
4.The minimum of h(x) is farther left and down from the minimums of f(x) and g(x).
Answer:
The minimum of h(x) is farther left and down from the minimums of f(x) and g(x) ⇒ answer 4
Step-by-step explanation:
* Lets revise the meaning of the minimum of the function
- The minimum of a function is the lowest point of a vertex
- The minimum value is the y-coordinate of the lowest point
* Now lets solve the problem
∵ f(x) = √x
- The domain of the function is all the real numbers ≥ 0, because
there is no square root for negative numbers
- We will use the first value of x to find the range of the function
∵ x = 0 ⇒ first value of the domain
∴ f(0) = √0 = 0
∴ The minimum of f(x) is point (0 , 0)
∵ g(x) = √(x - 3) + 1
- Lets find the domain of the function
∵ x - 3 ≥ 0 ⇒ add 3 for both sides
∴ x ≥ 3
∴ The domain of the function is all real values of x ≥ 3
- We will use the first value of x to find the range of the function
∵ x = 3 ⇒ the first value of the domain
∴ g(3) = √(3 - 3) + 1 = 0 + 1 = 1
∴ The minimum of g(x) is point (3 , 1)
∵ h(x) = √(x + 1) - 2
- Lets find the domain of the function
∵ x + 1 ≥ 0 ⇒ subtract 1 for both sides
∴ x ≥ -1
∴ The domain of the function is all real values of x ≥ -1
- We will use the first value of x to find the range of the function
∵ x = -1 ⇒ the first value of the domain
∴ h(-1) = √(-1 + 1) - 2 = 0 - = -2
∴ The minimum of h(x) is point (-1 , -2)
* To find the correct answer look to the minimum points of the
functions (0 , 0) , (3 , 1) , (-1 , -2)
- The minimum of f(x) lies on the origin
- The minimum of g(x) lies in the 1st quadrant
- The minimum of h(x) lies in the 3rd quadrant
∴ The minimum of h(x) is farther left and down from the minimums
of f(x) and g(x)
- Look to the attached graph to more understand
- The red curve is f(x)
- The blue curve is g(x)
- The green curve is h(x)
Final answer:
The minimums of f(x) and g(x) are in the first quadrant, and h(x) is in the fourth quadrant, making the minimum of h(x) farther right and up from the minimums of f(x) and g(x).
Explanation:
To compare the relative locations of the minimums of the functions f(x) = √x, g(x) = √x - 3 + 1, and h(x) = √x + 1 - 2, we need to consider how transformations affect the graph of the square root function.
The function f(x) is the parent square root function. Its minimum is at the origin (0,0), which is in the first quadrant.
The function g(x) is a horizontal translation 3 units to the right and a vertical translation 1 unit up from the function f(x). Hence, its minimum would also be in the first quadrant.
The function h(x) is a horizontal translation 1 unit to the right and a vertical translation 2 units down from f(x), which places its minimum in the fourth quadrant because the downward translation moves it below the x-axis.
Thus, the correct statement is: 3. The minimum of h(x) is farther right and up from the minimums of f(x) and g(x).
2. What is the equation of the line parallel to the line whose
equation is 5y + 9 = -2x ?
[1] y=-2x +3 [2] y = 2x + 1
B] y = x+4
[4] y=-x-1
Step-by-step explanation:
Paralle lines have the same slope.
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
We have
[tex]5y+9=-2x[/tex]
Convert to the slope-intercept form:
[tex]5y+9=-2x[/tex] subtract 9 from both sides
[tex]5y=-2x-9[/tex] divide both sides by 5
[tex]y=-\dfrac{2}{5}x-\dfrac{9}{5}\to m=-\dfrac{2}{5}[/tex]
Each of the answers to choose from is not the line equation sought.
The equation:
[tex]y=-\dfrac{2}{5}x+b[/tex] where b is any real number.
Parallel lines share the same slope. The slope of the given line is -2/5, so none of the provided options are correct as none have this slope.
Explanation:To find the equation of a line that is parallel to another, it's important to know that parallel lines have the same slope. So firstly, we need to find the slope of the given equation. Starting with 5y + 9 = -2x, we will rearrange this into slope-intercept form (y = mx + b), where 'm' is slope and 'b' is y-intercept.
Subtract 9 from both sides to get 5y = -2x - 9.Divide every term by 5 to get y = -2/5x - 9/5.So, the slope of the given line is -2/5. This means a parallel line will also have the slope -2/5. Therefore, neither [1] y=-2x +3 nor [2] y = 2x + 1, [3] y = x+4 and [4] y=-x-1 can be parallel to the given line because all of them have different slopes not equal to -2/5.

Answer:
[tex]cos(C) =\frac{40}{41}\\\\cos(C)=0.976[/tex]
Step-by-step explanation:
To find the [tex]cos (C)[/tex] we must use the cosine theorem.
The cosine theorem says that:

Question 1 (Essay Worth 10 points)
(08.01 MC)
The graph shows two lines, A and B.
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 5, 0. Another straight line labeled B joins the ordered pair 0, 2 with the ordered pair 6, 6.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer. (5 points)
Part B: What is the solution to the equations of lines A and B? Explain your answer. (5 points)
The pair of equations has one solution and the solution is (30/11, 20/11).
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
The coordinates on one line are (2, 6) and (5, 0)
Here, m=(0-6)/(5-2)
= -2
Substitute m=-2 and (2, 6) in y=mx+c, we get
6=-2(2)+c
c=10
So, the equation of a line is y=-2x+10 -----(i)
The coordinates on another line are (0, 2) and (6, 6)
Here, m= (6-2)/(6-0)
= 2/3
Substitute m=2/3 and (0, 2) in y=mx+c, we get
2=2/3(0)+c
c=0
So, the equation is y=2/3 x -----(ii)
Substitute equation (ii) in (i), we get
2/3 x=-2x+10
2x/3 +3x =10
11x=30
x=30/11
Substitute x=30/11 in equation (ii), we get
y =2/3 × 30/11

Find the height of the cone when the volume=300(pie) and the radius is 12
Answer:
The height of this cone is
[tex]\displaystyle \frac{25}{4}[/tex],
which is the same as 6.25 in decimals.
Step-by-step explanation:
Consider the formula for the volume [tex]V[/tex] of a cone:
[tex]\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h[/tex],
where
[tex]r[/tex] is the radius of the base of the cone, and[tex]h[/tex] is the height of the cone.For this cone,
[tex]V = 300\;\pi[/tex],[tex]r = 12[/tex], and[tex]h[/tex] is to be found.Rearrange the equation to find the height of this cone.
[tex]\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h[/tex],
[tex]3\;V = \pi \cdot r^{2}\cdot h[/tex],
[tex]\displaystyle \frac{3\;V}{\pi\cdot r^{2}} = h[/tex].
Therefore,
[tex]h = \displaystyle \frac{3\;V}{\pi\cdot r^{2}} = \frac{3\times 300\;\pi}{{12}^{2}\; \pi} = \frac{25}{4} = 6.25[/tex].

Answer:
37.5
Step-by-step explanation:
Since it is a cube, all of the lengths are equal. To find the surface area, you do
2.5*2.5 which is 6.25. After we get the 6.25, we need to find how many faces are there in this cube. (Including the base) There are 6 bases, then you take 6.25*6 to get the surface area. The final answer would be 37.5
Which function has real zeros at x = −10 and x = −6? f(x) = x2 + 16x + 60 f(x) = x2 − 16x + 60 f(x) = x2 + 4x + 60 f(x) = x2 − 4x + 60
Answer:
[tex]\large\boxed{f(x)=x^2+16x+60}[/tex]
Step-by-step explanation:
The factored form of a quadratic function:
[tex]f(x)=ax^2+bx+c=a(x-x_1)(x-x_2)[/tex]
x₁, x₂ - the zeros
We have x₁ = -10 and x₂ = -6.
Substitute:
[tex]f(x)=(x-(-10))(x-(-6))=(x+10)(x+6)[/tex]
Use FOIL: (a + b)(c + d) = ac + ad + bc + bd
[tex]f(x)=(x)(x)+(x)(6)+(10)(x)+(10)(6)\\\\f(x)=x^2+6x+10x+60\\\\f(x)=x^2+16x+60[/tex]

Find the slope of a line given the following points: (-1, 4) and (-5, 4). 0 1 4
Answer:
0
Step-by-step explanation:
The y-coordinates of the points are the same, so it is a horizontal line with a slope of 0.
___
slope = (change in y)/(change in x) = (4 -4)/(-5-(-1)) = 0/-4 = 0
ANSWER
0
EXPLANATION
The slope of a straight line is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
The given line passes through (-1,4) and (-5,4).
We substitute the points into the formula to get:
[tex]m = \frac{4 - 4}{ - 5 - - 1} [/tex]
[tex]m = \frac{4 - 4}{ - 5 + 1} [/tex]
This simplifies to:
[tex]m = \frac{0}{ - 4} [/tex]
Zero divided by any number is zero.
Therefore, the slope is:
[tex]m = 0[/tex]
I need help with this math question. It is really hard.
What is 2x+20=100
The answer for this math equation is x = 40 or just 40
Step-by-step explanation: You just need to solve this problem in the normal algebraic equation format, applying the rules too.
2x + 20 = 100
2x + 20 - 20 = 100 - 20
2x = 80
2x/2 = 80/2
x = 40
Step 1: Bring 20 to the right side of the equation by subtracting 20 to both sides (subtraction is the opposite of addition and will cancel 20 from the left side and bring it over to the right)
2x + (20 - 20) = 100 - 20
2x + 0 = 80
2x = 80
Step 2: To isolate x divide 2 to both sides (division is the opposite of multiplication and will cancel 2 from the left side and bring it over to the right)
2x ÷ 2 = 80 ÷ 2
x = 40
Check (plug in 40 for x and solve it like normal):
2(40) + 20 = 100
80 + 20 = 100
100 = 100 --------------------------------------> Correct!
