Answer:

D.) x - 4

Step-by-step explanation:

This is a graph of an exponential/quadratic function. There general structure looks like this:

ax² + bx + c

Generally, when finding the zeros these functions, you are told to factor the equation. Once you have factored the equation, you can set the factors equal to zero to find the points where the function touches the x-intercept.

That being said, you can determine the factors without having the entire equation by identifying the zeros on the function. On this graph, there is a zero at (4,0). This means that one of the factors must have been "x - 4". You can check your work by setting the factor equal to zero.

x - 4 = 0

x = 4

nida is buying a small storage box online. She sees a cube box with volume of 125cm^3. What is the length of each box edge?

aleksklad [387]

Answer:

5 cm

Step-by-step explanation:

Here, we want to get the length of each box edge

Let the length be s

Mathematically, the volume of a cube is s^3

Thus;

s^3 = 125

s^3 = 5^3

s = 5 cm

Ede4ka [16]

Answer:

The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50

Step-by-step explanation:

Let

x ---> amount that William has at the beginning

y ---> amount that Gracie has at the beginning

we know that

William says to Gracie, "If you give me $7.50,we will have and equal amount of money

so

$x+7.50=y-7.50$

$y=x+15.00$ ----> equation A

"Grace responds, if you give me $ 7.50 instead, I will have twice as much money as you

$2(x-7.50)=(y+7.50)$

$2x-15.00=y+7.50$

$2x-y=22.50$ ----> equation B

substitute equation A in equation B

$2x-(x+15.00)=22.50$

solve for x

$x=22.50+15.00=37.50$

Find the value of y

$y=37.50+15.00=52.50$

therefore

The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50

A club with 50 college students is doing volunteer work this semester. Each student is volunteering at one of four locations. He

Yuliya22 [10]

Answer: Our required probability is 0.58.

Step-by-step explanation:

Since we have given that

Number of students worked in Nursing home = 11

Number of students worked in Tutoring center = 13

Number of students worked in Soup kitchen = 8

Number of students worked in Library = 18

Total number of students = 50

Since 3 students are selected from the club.

We need to find the probability that none of the three students volunteer at the soup kitchen.

So, Remaining students would be 50-8 = 42

So, probability that none of three students at the soup kitchen is given by

$\dfrac{^{42}C_3}{^{50}C_3}\\\\=0.58$

Hence, our required probability is 0.58.
