lilavasa [31]

Answer:

7 digits

Step-by-step explanation:

When we multiply a two digit number like 17 by another 2 digit

The highest number of digits we can get as answer is 4 digits

This can be seen in the case of 10 * 10

So what this mean is that at any point in time, we can sum the numbers to get the digits

3 + 4 will give 7

Given f(x) =x-7 and g(x) =x2 find g(f(4))
8090 [49]

Answer: g(f(4))=9

Step-by-step explanation:

To find g(f(4)), you first find f(4). Then, you plug it into g(x).

f(4)=4-7            [subtract]

f(4)=-3

Now, we know f(4) into g(x).

g(f(4))=(-3)²      [exponent]

g(f(4))=9

Now, we know that g(f(4))=9.

The number of birds in a forest is decreasing by 3% every
AlexFokin [52]

Answer:

4266

Step-by-step explanation:

Okay! let's start with finding what 3% of 5400 birds is

3% is .03 as a decimal. We can find 3% of 5400 by multiplying 5400 by .03

5400×.03= 162

If our rainforest is losing 3% a year, that means we are losing 162 birds a year.

Let's turn it into an equation! x will be the number of years

5400-162x= number of birds left after x years

Now put 7 in for x

5400-(162×7)= 4266 birds

Hope this helps!
