#1,

The domain is all of the x-values.

The x-values of the set are: 2, 15, 21, 24

Your answer is C.


#2,

Part A)
Yes, the data in the table represents a function because each x-value has exactly one y-value. Also, the function passes the vertical line test.

Part B)
f(x) = 5x - 21
f(11) = 5(11) - 21
f(11) = 55 - 21
f(11) = 34

The table has a y-value of 8, when x = 11.

Therefore, f(x) = 5x - 21 has a greater value than the table when x = 11

Part C)
f(x) = 99
f(x) = 5x - 21

5x - 21 = 99
5x = 120
x = 24

The value of x is 24.

Formula for the surface area of a cylinder, SA = 2ar2 + 2arh. Solve for h.
MakcuM [25]

Answer:

h=\frac{SA-2\pi r^2}{2\pi r}

Step-by-step explanation:

The formula for the surface area of a cylinder is:

SA=2\pi r^2+2\pi rh

And we want to solve for the height h.

First, subtract 2\pi r^2 from both sides. This yields:

2\pi rh=SA-2\pi r^2

Now, divide both sides by 2\pi r. This yields:

h=\frac{SA-2\pi r^2}{2\pi r}

And we're done!

In a survey 9/25 students ride the bus and 19/50 walk to school. What fraction of students ride the bus or walk?
san4es73 [151]
Well since 19/50 can't be simplified you have to double 9/25 which is 18/50 so then add 18 + 19 = 37 So 18/50 + 19/50 = 37/50 so 37/50 of the students ride the bus or walk to school.

Need help with son's homework I will give 30 points!!! Please show work
Elis [28]

Answer:

A. ⇒ The expression is b + 3

B. ⇒ The expression is 2b - 4

C. ⇒ The Dr's office is closer by 4 miles

Step-by-step explanation:

A.

∵ The distance between Daniel's house and his school is b miles

∵ The swimming pool is 3 miles farther from his school

∴ The distance between Daniel's house and the swimming pool is b + 3

B.

∵ The distance from Daniel's house to his Dr's office is 4 less than twice the distance from home to Daniel's school

∵ The distance between Daniel's house and his school is b

∴ The expression of distance from Daniel's house to his Dr's office is

   2b - 4

C.

∵ b = 3

∴ The distance between his house and swimming pool is:

   3 + 3 = 6 miles

∴ The distance between his house and Dr's office is:

   2(3) - 4 = 2 miles

∴ The Dr's office is closer to Daniel's house than the swimming pool by:

   6 - 2 = 4 miles
