Final answer:
To locate the person who moved from (0, 1) with a slope of -4, we need to know the specific horizontal distance they moved. Without this, we can only say they moved downward 4 units for every 1 unit they moved to the right.
Explanation:
The student's question involves determining the position of a person who has moved along a slope on a coordinate plane. Since the individual started at the point (0, 1) and moved to the right with a slope of -4, we can assume they are moving in the negative y-direction (downward), as the negative slope indicates a decrease in y for every increase in x. The specific horizontal distance isn't given, so we cannot provide an exact new coordinate without more information. However, if we had a specific horizontal distance the person moved, we could calculate the new position using the slope (-4), which means for every 1 unit moved horizontally to the right, the person would move 4 units down.
Write all possible digits to make the number 132* multiple of 2 and 3 but not 5.
Answer:
6
Step-by-step explanation:
In order for 132* to be a multiple of 2, the digit * must be even.
In order for 132* to be a multiple of 3, the sum of all digits must be a multiple of 3. That is (1 +3 +2 + *) = 6+* is a multiple of 3. Since 6 is already a multiple of 3, then * must be a multiple of 3.
Single-digit values of * that are both even and a multiple of 3 are 0 and 6. We know that any number ending in 0 will be a multiple of 5, so we cannot use that digit.
The only possible digit that makes 132* a multiple of 2 and 3, but not 5, is 6.
The position of an object at time t is given by s(t) = 1 - 10t. Find the instantaneous velocity at t = 10 by finding the derivative.
I know I have to use the differential quotient formula:
f(x-h) - f(x) / h
Answer:
-10
Step-by-step explanation:
Velocity is the derivative of position. Derivative is defined as:
f'(x) = lim(h->0) [ f(x+h) - f(x) ] / h
s(t) = 1 - 10t
s(t+h) = 1 - 10(t+h)
Plugging in:
s'(t) = lim(h->0) [ 1 - 10(t+h) - (1 - 10t) ] / h
s'(t) = lim(h->0) (1 - 10t - 10h - 1 + 10t) / h
s'(t) = lim(h->0) (-10h) / h
s'(t) = lim(h->0) -10
s'(t) = -10
v(t) = -10
So at t=0, v(0) = -10.
The instantaneous velocity at [tex]t = 10[/tex] is 10.
The instantaneous Velocity of the object at a time [tex]t[/tex] is determined by mathematical concept of Derivative, whose description is shown below:
[tex]v = \lim_{h \to 0} \frac{s(t+h) - s(t)}{h}[/tex] (1)
Where:
[tex]h[/tex] - Time difference.
[tex]s(t)[/tex] - Function position evaluated at time [tex]t[/tex].
If we know that [tex]s(t) = 1 - 10\cdot t[/tex], then the instantaneous Velocity of the object is:
[tex]v = \lim_{h \to 0} \frac{1-10\cdot (t+h)-1+10\cdot t}{h}[/tex]
[tex]v = \lim_{h \to 0} \frac{10\cdot h}{h}[/tex]
[tex]v = \lim_{h \to 0} 10[/tex]
[tex]v = 10[/tex]
As instantaneous velocity is a constant function, it means that objects travels at constant velocity. Hence, we conclude that the instantaneous velocity at [tex]t = 10[/tex] is 10.

What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
Because each triangle has a right angle and shares an angle, we have three comparable triangles. The angles should be written from opposite to the short leg, long leg, and hypotenuse.
CAB is similar to BAD similar to CBD
CA : AB : CB = BA : AD : BD = CB : BD : CD
We also know
AC = AD + CD
(AD + CD) : AB : CB = BA : AD : BD = CB : BD : CD
(AD + CD)/CB = CB/CD
We have CB = 6, AD = 5, and x = CD.
∴ (5 + x)/6 = 6/x.
x(5 + x) = 36.
5x + x² = 36.
x² + 5x - 36 = 0.

A model rocket is fired from the ground at time t=0, and it’s height is given in cm by the formula h=-490t^2 +1470t where t is measured in seconds.
Write an equation to find when the height of the rocket is 980 cm.
Solve the equation by factoring.
Explain why there are two solutions to this problem.
Step-by-step explanation:
h = -490t² + 1470t
When h = 980:
980 = -490t² + 1470t
Simplifying:
0 = -490t² + 1470t - 980
0 = t² - 3t + 2
Factoring:
0 = (t - 1) (t - 2)
t = 1, 2
There are two solutions because the rocket first reaches the height of 980 cm as it's going up at 1 second, then it reaches that height again as it's coming down at 2 seconds.
The rocket reaches a height of 980 cm at 1 second and 2 seconds. The equation is factored to find these solutions, symbolizing the ascent and descent of the rocket.
To find when the height of the rocket is 980 cm, we set the height formula equal to 980 cm:
h = -490t² + 1470t = 980.
We then solve the equation by factoring:
-490t² + 1470t - 980 = 0
Divide by -10:
t²- 3t + 2 = 0
Factor:
(t - 1)(t - 2) = 0
Setting each factor to zero gives us the solutions:
t = 1 second
t = 2 seconds
There are two solutions because the rocket reaches 980 cm twice: once on its way up and once on its way down. This is demonstrated by the positive and negative components of the parabolic trajectory represented by the quadratic equation.

Recall that the area of an equilateral triangle with side length [tex]s[/tex] is [tex]\dfrac{\sqrt3}4s^2[/tex].
In the [tex]x-y[/tex] plane, the base is given by two equations:
[tex]x^2+y^2=9\implies y=\pm\sqrt{9-x^2}[/tex]
so that for any given [tex]x[/tex], the vertical distance between the two sides of the circle is
[tex]\sqrt{9-x^2}-\left(-\sqrt{9-x^2}\right)=2\sqrt{9-x^2}[/tex]
and this is the side of length of each triangular cross-section for each [tex]x[/tex]. Then the area of each cross-section is
[tex]\dfrac{\sqrt3}4(2\sqrt{9-x^2})^2=\sqrt3(9-x^2)[/tex]
and the volume of the solid is

Use the substitution method to solve the system of equations.Choose the correct ordered pair.
Hello there! The answer is B. (3, 21).
So you want to be able to substitute one of the equations into the other. We can't do this right now since both of the equations are y = something, so we need to change the second equation to x = something so we can plug it in to the value of x in the first equation.
y = x + 18 can translate to x = y - 18. Now, plug "y - 18" into x in the first equation.
y = 10(y-18) - 9 and solve.
y = 10y - 180 - 9
-9y = - 180 - 9
-9y = -189
y = 21.
Now we have our y value, but we need our x value. Well, remember that y = x + 18? So, since y is 21, what plus 18 is equal to 21? The answer is 3, making our x value 3.
If x = 3 and y = 21, the ordered pair is (3, 21) or option B. I hope this was helpful and have a great day! :)

Identify the equation of the circle X that passes through (−3,−5) and has center (4,−7). HELP ASAP!!
Answer:
(x - 4)² + (y + 7)² = 53
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
here (h, k) = (4, - 7), so
(x - 4)² + (y + 7)² = r²
The radius is the distance from the centre to a point on the circle.
Use the distance formula to calculate r
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (4, - 7) and (x₂, y₂ ) = (- 3, - 5)
r = [tex]\sqrt{(-3-4)^2+(-5+7)^2}[/tex]
= [tex]\sqrt{(-7)^2+2^2}[/tex] = [tex]\sqrt{49+4}[/tex] = [tex]\sqrt{53}[/tex]
Hence r² = ([tex]\sqrt{53}[/tex] )² = 53
(x - 4)² + (y + 7)² = 53 ← equation of circle

The tallest living man at one time had a height of 265 cm. The shortest living man at that time had a height of 109.1 cm. Heights of men at that time had a mean of 173.73 cm and a standard deviation of 8.65 cm. Which of these two men had the height that was more extreme?
Answer:
tallest man height is more extreme.
Step-by-step explanation:
Given:
Heights of men at that time had a mean of 173.73 cm and a standard deviation of 8.65 cm.
Concept used:
Convert height into z scores for comparison of deviation from the mean.
Solution:
Tallest man height = 265 cm
[tex]Z_{tall} =\frac{265-173.73}{8.65} \\=10.55[/tex]
Shortest man height = 109.1 cm
[tex]Z_{short} =\frac{109.1-173.73}{8.65} \\=-7.47[/tex]
Thus we find that tallest man is 10.55 std deviations from the mean to the right and shortest man is 7.47 std deviations from the mean to the left.
Hence tallest man height is more extreme.
The tallest living man at one time had a more extreme height compared to the shortest living man at that time.
Explanation:In this question, we are given the heights of the tallest and shortest living men at a specific time, as well as the mean and standard deviation of heights at that time. To determine which man had a more extreme height, we need to compare their heights to the mean and see how many standard deviations away they are.
The tallest man had a height of 265 cm, which is 265 - 173.73 = 91.27 cm above the mean.
The shortest man had a height of 109.1 cm, which is 173.73 - 109.1 = 64.63 cm below the mean.
Since the tallest man's height is significantly farther away from the mean compared to the shortest man's height, we can conclude that the tallest man had a more extreme height.

WE have to determine the lengths of all sides before finding the perimeter and area.
The formula of modulus is:
[tex]d = \sqrt{(x_{2}- x_{1})^{2} +(y_{2}-y_{1})^{2}}\\AB=\sqrt{(16-2)^{2} +(2-8)^{2}}\\=\sqrt{(14)^{2} +(-6)^{2}}\\=\sqrt{196+36}\\ =\sqrt{232}\\=15.23\\\\BC=\sqrt{(6-16)^{2} +(2-2)^{2}}\\=\sqrt{(-10)^{2} +(0)^{2}}\\=\sqrt{100+0}\\ =\sqrt{100}\\=10\\\\AC=\sqrt{(6-2)^{2} +(2-8)^{2}}\\=\sqrt{(4)^{2} +(-6)^{2}}\\=\sqrt{16+36}\\ =\sqrt{52}\\=7.21\\\\[/tex]
So the perimeter is:
[tex]Perimeter=AB+BC+AC\\=15.23+10+7.21\\=32.44\ units[/tex]
Using hero's formula,
[tex]s=\frac{perimeter}{2}\\s=\frac{32.44}{2}\\ s=16.22\\Area=\sqrt{s(s-a)(s-b)(s-c)}\\=\sqrt{16.22(16.22-15.23)(16.22-10)(16.22-7.21)}\\=\sqrt{(16.22)(0.99)(6.22)(9.01)}\\=\sqrt{899.91}\\=29.99\ square\ units[/tex]

Week 1: 85 sit-upsWeeks 2 to 5: 4 weeks x 90 sit-ups each week = 360 sit-upsTotal after 5 weeks: 85 + 360 = 445 sit-upsFor Christina:
Week 1: 65 sit-upsWeeks 2 to 5: 4 weeks x 90 sit-ups each week = 360 sit-upsTotal after 5 weeks: 65 + 360 = 425 sit-upsTherefore, after 5 weeks, Brian will have done 445 sit-ups and Christina will have done 425 sit-ups.
The athlete’s salary, in thousands, for the first two years is $400 and $400(1.05). The approximate salary, in thousands, earned each year for the first five years is $400, $420, $441, $463, and $486. Explain how you can evaluate the fifth partial sum. What does the fifth partial sum represent?
Answer:
Add the five terms.
Use the formula for the fifth partial sum.
The fifth partial sum represents the total amount of money the athlete earns over the first five years.
Step-by-step explanation:
Add the five terms.
Use the formula for the fifth partial sum.
The fifth partial sum represents the total amount of money the athlete earns over the first five years.
Answer: The fifth partial sum = 2210
The fifth partial sum represent the sum of the first 5 terms in the sequence.
Step-by-step explanation:
We know that he partial sum of a sequence gives the sum of the first n terms in the sequence.
Thus, the fifth partial sum represent the sum of the first 5 terms in the sequence.
The given geometric sequence : $400, $420, $441, $463, and $486.
Now, the fifth partial sum of the above sequence will be :
[tex]S_5=\$400+ \$420+ \$441+ \$463+\$486=\$2210[/tex]
Any number that can be written as a ratio of two integers
Final answer:
A number that can be expressed as a ratio of two integers is called a fraction. Ratios compare quantities and can be written in various forms, like fractions or with a colon. Proportions represent the equivalence of two ratios and are widely used in both mathematics and science.
Explanation:
Any number that can be written as a ratio of two integers is known as a fraction. A fraction is a type of ratio where one integer, the numerator, is divided by another integer, the denominator. For instance, 5/8 is a fraction because it represents 5 parts out of a total of 8.
A ratio can compare any two quantities, not just parts of a whole. These can be written as fractions, with a colon, or with the word 'to'. Examples include 2/3, 2:3, . Ratios are often used to compare dimensions, such as on a map where a unit scale is provided. For example, a map might state that 1 inch represents 100 feet, which is a ratio written as 1 inch/100 ft. Ratios are also essential in the health sciences, for instance, when describing solutions with a certain proportion like 1:1000.
In more complex applications, proportions are used to express equivalences between two ratios. For example, 1/2 is equivalent to 3/6, and this relationship forms a proportion. Proportions are useful in various fields, for setting up equivalencies and solving for unknown quantities.

WILL GIVE BRAINLIEST AND 25 POINTS HURRY (has to be correct tho !)
Answer:
i am assuming 2 and 5 because they are the only ones that are not like the others
Step-by-step explanation:
Answer:
Angles 2 and 5
Step-by-step explanation:
Supplement angles are the angles which up to 180 degrees.
And all the angles shown are Vertically opposite angles and these angles are always the same.
Vertically opposite angles:
Angles 2 and 5
Angles 1 and 3
Angles 6 and 4
As shown in the picture, Angle 2 is 90 degrees and angle 5 being a vertically opposite angle, angle 5 is 90 degrees too.
90 + 90 = 180 degrees.
