Answer:

1, 104, 539, 727 people.

Step-by-step explanation:

This will be an exponential function.

The equation for such is f(x) = a(b)^{x}.

a = initial value, in this case, 21,802.

b = multiplier, in this case, 4.7.

x = time, in this case, 7.

1. Insert your variables:

f(x) = 21,802(4.70)^{7}

2. Solve parenthesis.

4.7^{7} = 50,662.312

f(x) = 21,802(50,662.312)

3. Solve.

(21,802)(50,662.312) = 1,104,539,727.23

You would round you answer off, since you can't have 23% of a person, and your answer would be 1, 104, 539, 727 people.

Inverse square root (x+3)​
QveST [7]

Answer:

The inverse function is f(x) = x^2 - 3

Step-by-step explanation:

To find the inverse of any function, start by switching the x and f(x) values.

f(x) = √(x + 3)

x = √(f(x) + 3)

Now solve for the new f(x). The result will be your inverse function.

x = √(f(x) + 3)

x^2 = f(x) + 3

x^2 - 3 = f(x)

simon makes 30 cakes gives 1/5 of the cakes to sali. He gives 10% of the 30 cakes to jane what fraction of the fake cakes does h
dexar [7]

Total number of cakes made by Simon = 30 cakes.

Number of cakes gave to Sali = 1/5 Of total cakes = 1/5 * 30 = 6 cakes.

Number of the cakes gave to Jane = 10% of 30 cakes

10% can be written as 10/100 in fracions and in decimals it would be 0.10.

Therefore, 10% of 30 cakes = 0.10 times 30 = 3 cakes.

Total number of cakes left = Total cakes made - Cakes gave to Sali - Cakes gave to Jane = 30-6-3

Therefore, Total number of cakes left = 21.

21 cakes left our of 30 cakes.

21 out of 30 could be written in fracion form as 21/30.

We can reduce this fracion in simplest form by dividing top and bottom by 3, we get

7/10.

Therefore, 7/10 fraction of the cakes does he have left.

5 Helga signs up to coach hockey. She
lianna [129]

Answer: 12 practice sessions

Step-by-step explanation:

You can represent the word problem in this equation: 200+50x<775 OR 200+50x=775

If you subtract 200 from 775, you’ll be left with: 50x=575

Count by fifties until you get to 575. You’ll notice that 50 doesn’t go into 575 evenly! However, this won’t matter, because Helga wants to make AT LEAST 775. So you can round up to 12 practices instead of 11, which will equal 800 dollars instead of 750.
