A)A cylinder with height 4 inches and radius 4 inches.

Step-by-step explanation:

Volume of a Cylinder = \pi r^2 h

Next, we determine the volume of the options being considered by Tommy.

Option A:

A cylinder with height 4 inches and radius 4 inches.

Volume =\pi *4^2*4=64\pi cubic inches

Option B

A cylinder with height 7 inches and diameter 4 inches.

Volume =\pi *2^2*7=28\pi cubic inches

Option C

A cylinder with height 5.5 inches and radius 3 inches.

Volume =\pi *3^2*5.5=49.5\pi cubic inches

Option D

A cylinder with height 6.5 inches and Base Area B = 4 pi inches squared.

Volume =4*6.5*\pi=26 \pi cubic inches

The cylinders in Option A will hold more soup than the other two cans Tommy is considering.

Answer:

Step-by-step explanation:

75% of x = 18

75/100 * x = 18 (x = total number of students)

solving

x = 24

total number of students = 24

Checking:

75/100 * 24 = 18

You want to have $25,000 for a down payment on a house 6 years from now. if you can earn 6.5 percent, compounded annually, on yo

STatiana [176]

Use compound interest formula:
Future value, F
25000=P(1+i)^n
where
P=present value to be found
i=annual interest rate = 0.065
n=number of years = 6
so
25000=P(1.065)^6
=>
P=(25000/1.065^6)=$17133.353

Seven less than two times a number is 29.

Alexxx [7]

2x-7=29

"Seven less than" => minus 7.
"Two times <u>a number</u>" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together,

-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)

Which of these values for p and a will cause the function f(x)=Pax to be an exponential growth function

vovikov84 [41]

The option are missing in the question. The options are :

A. P = 2, a = 1

B. $P=\frac{1}{2} ; a =\frac{1}{3}$

C. $P=\frac{1}{2} ; a =1$

D. P = 2, a = 3

Solution :

The given function is $f(x)= Pa^x$

So for the function to be an exponential growth, a should be a positive number and should be larger than 1. If it less than 1 or a fraction, then it is a decay. If the value of a is negative, then it would be between positive and negative alternately.

When the four option being substituted in the function, we get

A). It is a constant function since $2(1^x)=2$
