Answer:

the number of miles is 14,722

Step-by-step explanation:

The computation of the number of miles drive last year is shown below:

= Total cost ÷ cost per mile

= $1,560 + $3,740 ÷ $0.36 per mile

= $5,300 ÷ $0.36 per mile

= 14,722 miles

Hence, the number of miles is 14,722

The surface area of a sphere is 576pi square units. Which choice represents the volume of the sphere?
Leona [35]

Answer:

\large\boxed{V=2304\pi}

Step-by-step explanation:

The formula of a surface area of a sphere:

S.A.=4\pi R^2

R - radius

We have

S.A.=576\pi

Substitute and solve for R:

4\pi R^2=576\pi         <em>divide both sides by π</em>

4R^2=576          <em>divide both sides by 4</em>

R^2=144\to R=\sqrt{144}\\\\R=12

The formula of a volume of a sphere:

V+\dfrac{4}{3}\pi R^3

Substitute:

V=\dfrac{4}{3}\pi(12^3)=\dfrac{4}{3}\pi(1728)=(4)\pi(576)=2304\pi

What is the slope of the line that contains the points (-2, 7) and (2,3)
iVinArrow [24]

Answer:

C

Step-by-step explanation:

The correct answer is C, -1. This is because slope formula is y2-y1/x2-x1. When you put that in you get 3-7/2-(-2) which equals -4/4, or -1.

Leto [7]

Answer:

expressions which represent exponential decay:

A. 900(0.05)^t

B. 700(0.9)^x

Step-by-step explanation:

Exponential decay functions has the next form:

y = ab^x

where b < 1

A. 900(0.05)^t , a = 900, b = 0.05, the variable is t instead of x. 0.05 < 1, then it represents exponential decay

B. 700(0.9)^x , a = 700, b = 0.9 < 1, then it represents exponential decay

C. 53(1.75)^(0.3x) =  53(1.75)^(0.3)(1.75)^x, a =  53(1.75)^(0.3), b = 1.75 > 1, then it doesn't represent exponential decay

D. 90(1.2)^t, a = 90, b = 1.2 > 1,  then it doesn't represent exponential decay. (the variable is t instead of x)

E. .300(2.4)^(1.2y)  = 300(2.4)^(1.2)(2.4)^y, a = 300(2.4)^(1.2),  b = 2.4 > 1, then it doesn't represent exponential decay. (the variable is y instead of x)

F. 2x² + 9 , this is a quadratic function,  then it doesn't represent exponential decay.

G. 18 – 3y, this is a linear function,  then it doesn't represent exponential decay.
