Robert sketches two rectangular prisms, A and B. Prism A's side lengths are 5 centimeters, 6 centimeters and 7 centimeters. Prism B's side lengths were twice those of prism A's: 10 centimeters,12 centimeters, and 14 centimeters. Robert says that surface area of prism B is twice the surface area of prism A. Is he correct? If he is not, how many times as great as prism A's surface area is prism B's surface area? Show your work.

Answers

Answer 1
Answer: fasle
LH=legnth times height
HW=height times width
LW=legnth times width
surface area=2(LH+LW+WH)

A surface area is 2(5*6+5*7+6*7)=214

b surface area is double everybody si
2(10*12+10*14+12*14)=856

214 times 2=428


he is wrong

how many times as great?
856/214=4

answer is 4 times

net is second drawing

Suppose a population has a doubling time of 25 years. By what factor will it grow in 25 years? 50 years? In 100 years?

Answers

Answer:

2,4, and 8.

Step-by-step explanation:

If the population has a doubling time of 25 years, that means that in 25 years the population will double. So for 25 years, the factor will be 2. For 50 years, the factor would be 2x2, which is 4. For 100 years, it is 4x2 which is a scale factor of 8.

You Guys Are Smart Please Help!A scuba diver dove from the surface of the ocean to an elevation of −49 9/10
feet at a rate of −15.4 feet per minute. After spending 13.75 minutes at that elevation, the diver ascended to an elevation of −8 9/10
feet. The total time for the dive so far was 20 1/8
minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.


The rate of change of the diver's elevation was _____ft/min.

Answers

S=v*t=-49.9*13.75=-686.125 feet
ΔS=-686.125-(-8.9)=-677.225 feet

minutes
v=S/t=-677.25/6.375=-106.24 feet per minute
the rate was -106.24 feet per minute of change in the diver's elevation during the ascent

If y = f(x) = 2(4)x + c, find the value of "c" that results in a graph with x-intercept at (2, 0).A) −32
B) −8
C) 32
D) 8

Answers

Answer:

Option A) −32

Step-by-step explanation:

we have

f(x)=2(4)^(x)+C

we know that

For x=2, f(x)=0 ----> given problem

so

substitute the value of x and the value of f(x) in the function above and solve for C

0=2(4)^(2)+C

0=2(16)+C

0=32+C

C=-32
