Select "growth" or "decay" to classify each function. function growth decay y=200(0.5)^2t y=1/2(2.5)^t/6 y=(0.65)^t/4 which equation can be used to find the solution of (1/3)^d−5 = 81 ? a. −d−5=4 b. d + 5 = 4 c. d−5=4 d. −d+5=4 the initial number of views for a blog was 20. the number of views is growing exponentially at a rate of 20% per week. what is the number of views expected to be four weeks from now? round to the nearest whole number. enter your answer in the box. which equations model exponential decay? select each correct answer. a. y=0.55(0.91)^x b. y=4.2(1.25)^x c. y=0.25(2)^x c. y=2(0.20)^x

1) An exponential function,

is called

Growth function : If b > 1

Decay function : if 0 < b < 1

Thus, the Growth function :

And, decay functions :

2) Given equation,

Thus, Option 'D' is correct.

3) Given,

The initial number for blog, P = 20,

Rate per week, r = 20% = 0.2

So, the number of blocks after x weeks,

Hence, the number of blocks after 4 weeks,

4) ∵ 0.55 < 1 and 0.20 < 1

so, the exponential decay functions,

A.

C.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
