Answer:

a. E(a) = (a+1)²

b. E(a + h) = (a+h+1)²

c. E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

Step-by-step explanation:

E(z)=(z+1)²

E(a) = (a+1)²

E(a + h) = (a+h+1)²

E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

Three squares. The first square is labeled with side length 1 inch on the vertical side and 1 inch on the horizontal side. The s
dlinn [17]

Answer:

The area is the side lengths squared or multiplied by themselves. The three squares have very different areas based on their side lengths. I disagree that a square with 13 inch side length will have area 13. It will have area 13*13=169 square inches.

Step-by-step explanation:

The area of a square is A=s*s.

1st: A = 1*1 = 1 square inches.

2nd: A=1/2*1/2 = 1/4 square inches

3rd: A =2*2 = 4 square inches.

The area of a square with 1 unit side length is still 1. But a square whose side is less than 1 has a very small area and the square whose side length is greater than 1 has a much larger area. The area of a square is the square of its side length or its side length times itself.

Knowing this, a square with side length 13 will not have area 13 but area 169.

With the ratio at 1:1, Point C appears to be the midpoint. Use the midpoint formula to ascertain (make sure of) whether Point C
Mila [183]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete because the coordinates of A, B and C were not given in the question.

However, the following explanation will guide you...

The midpoints, C of two point A and B is calculated as:

C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})

Where (x_1, y_1) are the coordinates of A

and

(x_2,y_2) are the coordinates of B

Take for instance, the given coordinates are

A(4,6); B(2,4) and C(3,5)

Then;

Plug in these values in the given formula:

C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})

(3,5) = (\frac{4 + 2}{2}, \frac{6 + 4}{2})

(3,5) = (\frac{6}{2}, \frac{10}{2})

(3,5) = (3,5)

In that case,

C is really the midpoint

To the b part: <em>Explaining why ratio 1:1 is used</em>

The reason is that both parts of the ratio are in equal proportion (1 and 1);

Because of this equal proportion, ration 1:1 is right to calculate the midpoint

leva [86]

Use the Pythagorean theorem:

Height is 14, base is 3, so we can calculate the length required.

Length = sqrt(14^2 + 3^2)

Length = sqrt( 196 + 9)

Length = sqrt(205)

Length = 14.32 feet.

The ladder needs to be 14.32 feet. The longest her ladder can be is 14 feet so her ladder won’t work.
