Answers

Answer 1

Answer:

Because if you give the power of 2 to all of them you get a different number

1. 20 squared+ 21 squared = 841

Answer to number 1

Answer 2

1) 20+21 =41. Since 20^2+21^2 both have ^2 on top. The ^2 would stay the same. So that means the answer would be 41^2 for the first one which is why it is incorrect

2)Same for this. 4^2+5^2= 9^2

3)a^2+b^2 = ab^2 because since a and b are different letters/variables you cannot combine them therefore it is just ab.

4) (-1)^2 = 1 because -1 multiply by -1 again you would get positive 1. Next you do 1+0^2 = 1. Because 0^2 is just 0 because 0times 0 =0 so 1+0 = 1

what does the a in y=a(1+r)x represent?

Answers

Answer:

The function is of the form y = a(1 − r)t, where 1 − r < 1, so it represents exponential decay. Use the decay factor 1 − r to find the rate of decay. Write an equation. Solve for r.

The "a" in the expression y = a (1+r)ˣ represents the initial amount.

What is the expression?

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given, a exponential expression y = a (1+r)ˣ

The exponential growth can alternatively be calculated using the formula f(x) = a(1 + r)ˣ, where the function is denoted by the f(x) term. The initial value of your data is represented by the variable. The growth rate is represented by the r variable.

Therefore, the initial amount is been represented by "a" in the given expression.

If a circle has a diameter of 23 inches, then the radius will be

Answers

Answer:

11.5 in

Step-by-step explanation:

The radius is half the diameter

23/2=11.5

If a circle has a diameter of 23 inches, then the radius will be 12.5 inches.

What is the relation between the radius and the diameter of the circle?

The radius is half of the diameter of the circle, for calculating radius we can divide the diameter of the circle by 2.

Given that,

The diameter of the circle is equal to 23 inches.

d = 23 inches

It is known that,

The radius is half of the diameter of the circle,

so it can be written in the form expression as:

r = D/2

D = 23 inches

r = 23/2

= 12.5 inches

Hence, the radius of the circle 12.5 inches.

The triangles are congruent. Find the measure of x.

Answers

Match up the sides for each triangle using the little marks through the sides

1 to 1, 2 to 2 and 3 to 3

When you do this you see that x corresponds to c on the first triangle.

The 3 angles in a triangle = 180.

Find c by subtracting A and B from 180

C = 180- 29-63 = 88

Now x = c so x = 88

The answer is C. 88

solve for “x”.
