!30 POINTS! How can I use this trapezoid to prove the Pythagorean Theorem?

Answers

Answer:

Pythagorean Theorem: c2 = a2 + b2

Find the area by adding the areas of the three triangles. The area of a right triangle is: A = ½bh

Two triangles are identical so you can just multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab.

The total area of the trapezoid is : A1 + A2 = ab + ½c2

You multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2

You subtract out the 2ab: a2 + b2 = c2.

Then what is left is the proof: a2 + b2 = c2

Answers

Answer:

Domain is 3 <x>_-2

Range is 6 <x>_-3 (the lines are supposed to be under the >. it means equal to)

Step-by-step explanation:

First look on the x-axis, is goes from 3 to -2. now look at the colored in dot. that means more than or equal to. So the sign of -2 is x >_ -2. put the 3 on the other side. It stops at three so the sign is > 3. so 3<x>_ -2

Do the same with the y-axis except look up and down instead of left and right. so the numbers are 6 and -3. Use the same method above. this is set builder notation.

325.623 rounded to nearest hundredth

Answers

Answer:

325.62

Step-by-step explanation:

Find the number in the hundredth place  2  and look one place to the right for the rounding digit  3. Round up if this number is greater than or equal to  5  and round down if it is less than  5 .

325.62

When your rounding you look at the number next to the number your rounding to. For example: 325.623 the hundredths place is the 2 so the number next to it is 3.

When your rounding there is a saying ( there r different ways of saying it this is the way I was taught) 5 or more raise the score. 4 or less let it rest. Meaning if it’s 5 or more raise the number one level up ( 5 goes to 6, 6 goes to 7, 7 goes to 8, 9 goes to 10). If it’s 4 or less take away the numbers behind the number your rounding to. ( Example: 45.6478 if we r rounding to the nearest tenth we look at the 4 it’s 4 or less so it would be 45.6).

So 3 is less than 4 so we take away the numbers behind the 2 therefore we get or answer 325.62

the slope is NEGATIVE 3/2

The y intercept is simple it is where a point intercepts the y-axis so that is (0,6) and the slope is (y2-y1)/(x2-x1)
(6-0)/(0-4) = 6/-4 = -3/2, so the equation is y=(-3/2)x+6.

y=3x+5

plug your coordinate points into the equation for slope (left corner or the paper)

multiply by the denominator on both sides of the equation

x-6 cancels out and leaves y-23=3(x-6)

multiply x and -6 by 3

add 23 to both sides to isolate y

Please help me solve this ASAP

Answers

Answer:

There is no solution.

Step-by-step explanation:

In simplifying this, you'd start by distributing the negative sign on the left.

-(6x + 6) + 2 = -6x - 3 becomes -6x - 6 + 2 = -6x - 3.

Then you can add -6 and 2 on the left.

-6x - 6 + 2 = -6x - 3 becomes -6x - 4 = -6x - 3.

With that done, you can add 4 to both sides.

-6x - 4 = -6x - 3 becomes -6x = -6x + 1.

Then, add 6x to both sides.

-6x = -6x + 1 becomes 0 = 1.

Here, we run into an issue - 0 does not equal 1, and there is no way to avoid running into this while solving this equation. This means that this problem has no solution, there is no value that x can have that would make it true.

Step-by-step explanation:

We require to find the value of t which makes f(t) = 13

Equating the right sides gives
