Answer:

5

Step-by-step explanation:

First you want to find f(-2)

Then whatever f(-2) equal, you plug into g(x) to find g(f(-2))

So first lets find f(-2)

Looking at the f(x) graph. When -2 is inputted ( x value -2 ) the output is 1

So f(-2) = 1

We then plug in 1 into g(x) to find g(f(-2))

Think of it as 1 replacing f(-2) in g(f(-2)) because f(-2) = 1

So g(f(-2)) = g(1)

We then look at the graph g(x)

when 1 is inputted the output is 5

Therefore g(f(-2)) = 5

How to identify domain and range from co-ordinate pair.

  • If a pair be (x,y) then x is domain and y is range .

A scientist measured the amount of rain that fell in a town during
allochka39001 [22]

Answer:

1.47 mm

Step-by-step explanation:

In week 1 there was 2.6 mm

In week 4 there was 4.07

You want to find the difference of week 1 and 4 meaning you have to subtract week 4's value from week 1's to find how much more rain there was in week 4 than week 1

You would do 4.07-2.6

This is equal to 1.47

THEREFORE there was 1.47 mm more rain in week 4 than week 1

What group of numbers does -2 belong to?
Marizza181 [45]
Answer: Integers and Rational Numbers

Explanation: -2 is an integer because integers include positive an negative numbers. It would not be a whole number or a Naural number because both of those sets only include positive numbers. Here’s a better explanation:

Natural numbers: Natural Numbers are like (1,2,3....). They only include positive numbers. Therefore, -2 does not belong in this category.

Whole Numbers: Whole Numbers are like (0,1,2,3....). They include all the natural numbers with 0. Therefore, -2 does not belong in this set.

Integers: Integers include both positive and negative numbers. They are like (-3,-2,-1,0,1,2,3....). Since they both have positive and negative numbers, -2 would belong in this set.

Rational Numbers: Rational Numbers include ALL the sets that were described. (Natural, Whole, Integer). Since this set also includes positive and negative numbers, -2 would belong in this set.

So, -2 belongs in Integers and Rational Numbers

Hope this helps!

The triangles shown below must be congruent.
Ber [7]

Answer:

False

Step-by-step explanation:

The triangles are similar because the angles are the same

We know nothing about the side lengths, so we can say nothing about concurrency.  They may or may not be congruent.
