Answer:

Approximately 157.08 sq. cm.

Step-by-step explanation:

The Area of an Ellipse is given by the formula $A=\pi a b$

Here 2a = 10, so a = 5

Also, 2b = 20, b = 10

Substituting these into the area formula gives us:

$A=\pi a b\\A=\pi (5)(10)\\A=50\pi\\A=157.08$

The Area is approximately 157.08 sq. cm.

Which shows the expression below in simplified form? (2.4 × 1018) + (3.4 × 1015)

RUDIKE [14]

Answer: 5894.2

Step-by-step explanation:

You'll want to follow PEMDAS to simplify this expression.

1.) P - Parentheses

2.) E - Exponents

3.) M - Multiplication

4.) D - Division

5.) A - Addition

6.) S - Subtraction

We'll start with what's inside the parentheses:

(2.4 × 1018) + (3.4 × 1015)

(2,443.2) + (3,451)

Now all you have to do is add the values together to get your answer!

2,443.2 + 3,451

Slope intercept of (1,1) and (0,7)

Sonja [21]

Answer:

$\boxed {m = -6}$

Step-by-step explanation:

Use the Slope Formula to help you determine the slope of the following two points:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

(Where $(x_{1}, y_{1})$ is the first point and $(x_{2}, y_{2})$ is the second point)

-Apply both points onto that formula:

$(x_{1}, y_{1}) = (1, 1)$

$(x_{2}, y_{2}) = (0, 7)$

$m = \frac{7 - 1}{0 - 1}$

-Solve:

$m = \frac{7 - 1}{0 - 1}$

$m = \frac{6}{-1}$

$\boxed {m = -6}$

What is the area of a regular hexagon with an apothem 18.5 inches long and a side 21 inches

earnstyle [38]

The area of a regular hexagon with an apothem 18.5 inches long and a side 21 inches is 1, 165. 5 In²

<h3>How to calculate the area of a regular hexagon</h3>

The formula is given thus;

Area of hexagon = (1/2) × a × P

where a = the length of the apothem

P = perimeter of the hexagon

Given a = 18. 5 inches

Note that Perimeter, p = 6a with 'a' as side

p = 6 × 21 = 126 inches

Substitute values into the formula

Area, A = 1 ÷2 × 18. 5 × 126 = 1 ÷2 × 2331 = 1, 165. 5 In²

Thus, the area of the regular hexagon is 1, 165. 5 In²
