A right triangle follows the Pythagorean theorem: a^2 + b^2 = c^2

Let’s work out the problems
1. 20^2 + 72^2 = 75^2
40 + 5184 = 5625
False

2. 40^2 + 74^2 = 85^2
1600 + 5476 = 7225
False

3. 45^2 + 60^2 = 75^2
2025 + 3600 = 5625
True

The correct answer is (45, 60, 75)

The area formula of a circle is $r^{2}$ × π.

With that being said, we can solve both problems!

Starting with part A:

-The radius we know is 21cm. From there, we can substitute in our formula with the new value.

$21^{2}$ x π

From there, we can square our radius:

(21 x 21) x π

(441) x π

And finally, we can multiply by pi to get our answer.

(441) x π

1385.44236023

Which rounded to the nearest tenth is 1385.4. Therefore, the area of the porthole is 1385.4 centimetres.

The second part can be followed with the same process, hopefully you understand the concept enough to where you're comfortable solving problems like this on your own. Feel free to reach out if you have any further trouble!

Hope this helped! :)

Write an equation in slope-intercept form for this line.

sineoko [7]

Answer:

y = $\frac{3}{2}$ x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{3}{2}$ , then

y = $\frac{3}{2}$ x + c ← is the partial equation

To find c substitute (- 4, - 7 ) into the partial equation

- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1

y = $\frac{3}{2}$ x - 1 ← equation of line
