Line: y = -1/2x + 4 area: is 7/3 you'll have to find the slope of the tangent line first which is: y' = 2x - 2 = 2(2) - 2 = 2 the perpendicular slope is then -1/2 y - 3 = -1/2(x - 2) y = -1/2x + 4

then you integrate, by using the line as the upper area, then subtracting the lower area parabola between 0 and 2 int(-1/2x + 4 - (x^2 - 2x + 3)) = -1/4x^2 + 4x -x^3/3 + x^2 - 3x replace 2 for x and you will get -1 + 8 - 8/3 + 4 - 6 12 - 29/3 = 7/3

Describe what Pi is and explain how it is used in finding the circumference of a circle.
Softa [21]

Answer:

See below.

Step-by-step explanation:

Pi ( written as the Geek letter π) is a universal constant  found by dividing the circumference of a circle by it's diameter. So if you measure the diameter of a circle you can calculate it's circumference by multiplying by π.

Circumference = π * diameter.

It's value to the nearest hundredth is 3.14 but its actual value is a decimal number that goes on without bounds. That is in Maths it is irrational and can't be written accurately as a fraction.

Find the volume of this prism 8cm to 9cm to 11cm
vladimir2022 [97]

Answer:

V = 792 m3

I am kinda guessing on this since you didn't provide a unit or label what the height, width, and length are. Also you should specify what prism...

Solutions 

<span>Ivy has 4 tiles with pictures of plants and 5 tiles with pictures of animals. Ivy keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns another over tile without looking. What is the probability that the second tile that Ivy turns over has a plant on it. To solve the problem the first step is to find out how many tiles are in total. Since one of the plant tiles were removed we have 3 left. 
</span>
5 + 3 = 8

Now we find the percent by dividing 3 from 8. The top number is called  the NUMERATOR<span> and the bottom number is called the </span>DENOMINATOR<span>.</span>

3 ÷ 8 = 0.375

0.375 x 100 = 37.5

Answer = <span>37.5%

= (A)
