Hey there! This is the correct sentence.

Proving the converse of the Pythagorean theorem means that for any triangle ABC with verticles of a, b, and c such that angles triangle ABC is not a right triangle.

verticles

angles

side lengths

is not a right triangle

is a right triangle

(a+b)^2 =c^2

a^ 2 x b^2=c^2

a^2+b^2=c^2

Answer:

The answer is 236.52.

Step-by-step explanation:

First you want to figure out the radius of the semi circle so you take the length of 12 and divide it by 2. Then you want to use the formula for area of a circle 3.14 times radius squared and divide that by 2 and add 12x15 to get your answer.

Find the derivative of the following functions:

DerKrebs [107]

I will only do the first-three. You can repost number 4.

Question 1

f(x) = -x^2 + 10x + 4

dy/dx = -2x + 10

Question 2

f(x) = 20 - x + 2

dy/dx = -1

Question 3

f(x) = ex^4 - 2x^2

dy/dx = e•4x^3 + x^4 - 4x

dy/dx = 4ex^3 + x^4 - 4x

Jeffrey is a kickboxing instructor who will be teaching classes at a local gym. To get certified

tatyana61 [14]

If Jeffrey takes 50 classes in his first month as an instructor, he will earn back the amount he spent on certification.

Step-by-step explanation:

Amount spent on certification = $200

Base salary = $50

Payment per class = $3

Let, x be the number of classes.

J(x) = 50+3x

He needs to earn $200 dollars in first month, therefore,

50+3x=200

$3x=200-50\\3x=150$

Dividing both sides by 3

$\frac{3x}{3}=\frac{150}{3}\\x=50$

If Jeffrey takes 50 classes in his first month as an instructor, he will earn back the amount he spent on certification.

The isosceles triangle is a scale drawing of a flag.

Zolol [24]

Answer:

Scale factor = $\frac{1}{2}$

Step-by-step explanation:

Perimeter of the actual flag = 22 in.

Perimeter of the scale drawing of the flag = 11 in.

Since, perimeter of a triangle = Sum of all three sides of the given triangle

Therefore, scale factor of the drawing

= $\frac{\text{Measure of the side of drawing}}{\text{Measure of the side of actual}}$ = $\frac{\text{Perimeter of drawing}}{\text{Perimeter of actual}}$
