Jeff made $243.75 last week. If he worked 25 hours, how much is he paid for one hour of work?

Answer:

In an isosceles right triangle, the hypotenuse is larger than the sides by a factor of the square root of 2.

So, if the hypotenuse is 8 then the sides are 8 / (sq root of 2) = 5.6568542495

Step-by-step explanation:

By setting up a system of equations, it was determined that the local hamburger shop sold 350 hamburgers on Friday.

To determine how many hamburgers and cheeseburgers were sold on Friday at the local hamburger shop, we can set up a system of equations based on the information given. Let H represent the number of hamburgers sold and C represent the number of cheeseburgers sold. According to the problem, H + C = 625 and H = C + 75.

To find the number of hamburgers, we replace C in the first equation with H - 75 from the second equation, so we have H + (H - 75) = 625. Simplifying this, we get 2H - 75 = 625. Adding 75 to both sides gives us 2H = 700. Dividing both sides by 2 gives H = 350. Therefore, 350 hamburgers were sold on Friday.

Answer:

x = -12

Step-by-step explanation:

Step 1: Isolate x

1/4x + x = -12 - 3

Step 2: Combine like terms

5/4x = -15

Step 3: Simplify

x = (-15)(4/5)

x = -12

Answer: -12

Step-by-step explanation:−1 /4  x−12=x+3

Step 1: Subtract x from both sides.

−1 /4 x−12−x=x+3−x

−5 /4 x−12=3

Step 2: Add 12 to both sides.

−5 /4 x−12+12=3+12

−5 /4 x=15

Step 3: Multiply both sides by 4/(-5).

( 4 /−5 )*( −5 /4 x)=( 4 /−5 )*(15)

x=−12

Answer:

24

Step-by-step explanation:

4!  means multiply all the number from 4 down to 1

4! = 4*3*2*1

   = 24

For this case we have that by definition, the factorial of a number is the product of the "n" consvutive factors from n to 1. The factors are in descending order, that is:

[tex]n! = n (n-1) (n-2) ... 3 * 2 * 1[/tex]

Then, we have the following expression:

[tex]4![/tex]

Applying the definition we have:

[tex]4! = 4 * 3 * 2 * 1 = 24[/tex]

ANswer:

[tex]4! = 24[/tex]

Well to find the Mean you Add all of the numbers up and Divide by How many numbers there are

The sample mean is 26 mins and the population mean is 23 mins.

An average of a group of data is referred to as a sample mean.

The population mean is an average of a group characteristic.

The population mean = 23 minutes(given)

Sample mean = (25 + 33 + 26 + 29 + 17 + 29 + 42 + 19 + 15 + 52 + 11 + 14) / 12

Sample mean = 312 / 12

Sample mean = 26 minutes

Hence, the value of sample mean is 26 minutes and the value of population mean is 23 minutes.

a) Samuel has a better credit score, so his interest rate is lower.

Step-by-step explanation:

Alan and Samuel both are same age and make same amount of money.

They both have a 30-year mortgage. But Alan pays 5 percent interest, while Samuel only pays 3.5 percent.

There correct answer here will be - Samuel has a better credit score, so his interest rate is lower.

When a person has a good credit rating, that means he has never defaulted any payment and has always paid his loan on time. He must be a trusted customer for the bank that is why he got a lower interest rate than Alan.

Answer:

h(x) = –5 |x| + 10

k(x)=1/4(x-4)^2+4

m(x)=1/4 |x-8| +6

Step-by-step explanation:

The given function is:

g(x) = |x + 3| + 4

At y-intercept x=0,

g(0) = |0 + 3| + 4

g(0) = 3 + 4=7

The y-intercept of this function is 7.

We look for the functions with y-intercepts greater than 7.

[tex]f(x)=-2(x-8)^2[/tex]

[tex]f(0)=-2(0-8)^2[/tex]

[tex]f(0)=-128[/tex]

h(x) = –5 |x| + 10

h(x) = –5 |0| + 10=10

[tex]j(x)=-4(x+2)^2+8[/tex]

[tex]j(0)=-4(0+2)^2+8=-8[/tex]

[tex]k(x)=\frac{1}{4}(x-4)^2+4[/tex]

[tex]k(0)=\frac{1}{4}(0-4)^2+4=8[/tex]

m(x)=1/4 |x-8| +6

m(0)=1/4 |0-8| +6=8

Answer with explanation:

The given function is

  g(x)=|x+3|+4

The meaning of Y intercept is the distance between origin and Point where the curve cuts Y axis.

In , g(x), put x=0

g(0)=|0+3|+4

   =3+4

   =7

So, Length of Y intercept =7 unit

2.

f(x)=-2(x-8)²

f(0)=-2×(0-8)²

     = -2 × 64

      = -128

Length of Y intercept =-128 unit

3.

h(x)=-5|x|+10

h(0)=-5 × |0| +10

       =10

Length of Y intercept =10 unit

4.

j(x)=-4(x+2)²+8

j(0)=-4×(0+2)²+8

     =-4 × 4+8

    = -16 +8

    = -8

Length of Y intercept =-8 unit

4.

[tex]\rightarrow k(x)=\frac{1}{4} \times (x-4)^2+4\\\\\rightarrow k(0)=\frac{1}{4} \times (0-4)^2+4\\\\\rightarrow k(0)= 4+4\\\\=8[/tex]

Length of Y intercept =8 unit

5.

[tex]\rightarrow m(x)=\frac{1}{4} \times |x-8|+6\\\\\rightarrow k(0)=\frac{1}{4} \times |0-8|+6\\\\\rightarrow k(0)= 2+6\\\\=8[/tex]

Length of Y intercept =8 unit

⇒ h(x),k(x) and m(x) has y intercept greater than y-intercept of the function g(x) = |x + 3| + 4.

Step-by-step explanation:

1)  1

2) 5

3) 2

You are looking for the x values of this "rule". It gives you the y-values so all you have to do is plug the y-values into the rule and solve for x

y = 4 so...

4 = x + 3

4 - 3 = x + (3-3)

1 = x + 0

x = 1

When y is 4 then x is 1

y = 8 so...

8 = x + 3

8 - 3 = x + (3 - 3)

x = 5

When y is 8 then x is 5

y = 5 so...

5 = x + 3

5 - 3 = x + (3 - 3)

2 = x + 0

x = 2

When y is 5 then x is 2

Answer:

(8w -3) (w -1) =

8w^2-5w+3

Step-by-step explanation:

The first option is correct: we have

[tex]\left(k^{\frac{1}{8}}\right)^{-1} = \dfrac{1}{k^{\frac{1}{8}}} = \dfrac{1}{\sqrt[8]{k}},\quad \left(k^{-1}\right)^{\frac{1}{8}} = \left(\dfrac{1}{k}\right)^{\frac{1}{8}} = \dfrac{1}{\sqrt[8]{k}}[/tex]

The second option is also correct, because it simply applies the definition

[tex]k^{\frac{1}{n}} = \sqrt[n]{k}[/tex]

The third option is also correct, because it applies the rule

[tex](a^b)^c = a^{bc}[/tex]

The expressions equivalent to (k^(1/8))^(-1) are (k^(-1))^(1/8) and k^(-1/8), matching options a and c from the given choices. These are determined by correctly applying the exponent multiplication rule.

The student is dealing with an expression involving exponents and radicals, specifically focused on understanding the rules for combining and simplifying these expressions. The expression in question is (k^(1/8))^(-1), which we'll simplify in a step-by-step fashion.

The rule of exponents we need to apply here is (a^m)^n = a^(m*n). When applying this rule to the given expression we get:

(k^(1/8))^(-1) = k^(1/8 * -1)

Simplify the exponent:

k^(1/8 * -1) = k^(-1/8)

So, the equivalent expression is:

k^(-1/8)

Now let's examine the choices given:

Answer:

399

Step-by-step explanation:

If you want a polynomial to have the x-intercepts of your choice, you simply have to build a polynomial by multiplying pieces like [tex](x-x_k)[/tex] where [tex]x_k[/tex] is the x-intercept you want.

So, if you want x-intercepts 0 and 4, you have to build the polynomial

[tex](x-0)(x-4) = x(x-4)[/tex]

The function that has x-intercepts at (0, 0) and (4, 0) is f(x) = x (x − 4).

Option A is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The x-intercepts of a function are the points where the graph of the function crosses the x-axis.

At these points, the value of the function is zero.

To have x-intercepts at (0, 0) and (4, 0), the function must be zero when x is equal to 0 and 4.

Let's evaluate the given options:

f(x) = x(x − 4):

This function is zero at x = 0 and x = 4, so it has x-intercepts at (0, 0) and (4, 0).

f(x) = x(x + 4):

This function is zero at x = 0 and x = -4, so it does not have an x-intercept at (4, 0).

f(x) = (x − 4)(x − 4):

This function is zero at x = 4, but it also has a double root at x = 4, so it only has one x-intercept at (4, 0).

f(x) = (x + 4)(x + 4):

This function is zero at x = -4, but it does not have an x-intercept at (0, 0).

Therefore,

The function that has x-intercepts at (0, 0) and (4, 0) is f(x) = x(x − 4).

The area of the shaded region between a larger circle with a radius of 4 cm and a smaller circle with a radius of 2 cm is 12π cm². This is calculated by subtracting the area of the smaller circle from the area of the larger circle.

This concerns the area of the shaded area between two circles, one with a radius of two centimetres and the other with a radius of four centimeters.

In order to determine this, we first compute the area of each circle using the formula πr², where r is the circle's radius.

Let's start by calculating the area of the bigger circle: π(4cm)² = 16π cm² is the area.

In a similar manner, we can calculate the smaller circle's area: π(2cm)² = 4π cm² is the area.

The area of the shaded region is equal to the area of the larger circle minus the area of the smaller circle, or area = 16π cm² - 4π cm² = 12π cm².

Answer:

h = 10 m

Step-by-step explanation:

We are given the following formula of the area of a trapezoid:

[tex]A=\frac{1}{2} (b+c)h[/tex]

where [tex]h[/tex] is the height of the trapezoid and [tex]b[/tex] and [tex]c[/tex] are its bases.

Re-arranging the given formula to solve for h:

[tex]A=\frac{1}{2} (b+c)h[/tex]

[tex]2A=(b+c)h[/tex]

[tex]h=\frac{2A}{(b+c)}[/tex]

Finding the height of the trapezoid given the bases 20 m, 7 m and area 135m^2.

[tex]h=\frac{2 \times 135}{(7+20)}[/tex]

h = 10 m

ANSWER

h=10m

EXPLANATION

The given formula is

[tex]A = \frac{1}{2} (b + c)h[/tex]

We multiply through by 2 to get,

[tex]2A =(b + c)h[/tex]We divide both sides by (b+c) to get,

[tex] \frac{2A}{b + c}=h[/tex]

Or

[tex]h=\frac{2A}{b + c} [/tex]

[tex]h=\frac{2 \times 135}{20 + 7} [/tex]

We simplify to get,

[tex]h=\frac{270}{27} [/tex]

Therefore

[tex]h = 10[/tex]

Find the Greatest Common Factor (GCF)

GCF = 2xy

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2xy(8x^3y/2xy + -8x^2y/2xy + -30xy/2xy)

Simplify each term in parenthesis

2xy(4x^2 - 4x - 15)

Split the second term in 4x^2 - 4x - 15 into two terms

2xy(4x^2 + 6x - 10x - 15)

Factor out common terms in the first two terms, then in the last two terms;

2xy(2x(2x + 3) -5(2x + 3))

Factor out the common term 2x + 3

= 2xy(2x + 3)(2x - 5)

I'm going to assume you're saying 3x to the power of 2. So first, apply the values of the variables to the equation just as shown:

(-5)(-5)=25

Then, multiply 3 to 25:

3*25=75

Now, the absolute value of y is the absolute value of -2. The aboslute value of any number is its positive value, so now we are left with 75-2
