Payton found more information about bats. In parts (a) and (b) below, you will use the information she found to make predictions about the bats.
a.
The common vampire bat is native to northern Mexico and Central and
South America. It feeds on the blood of sleeping cows by making very
small cuts into their skin and then licking the wounds
Use your graph of bat length and wingspan to predict the wingspan of the
common vampire bat if it typically has a length of about 2.75 inches.
The Kitti's hog-nosed bat, also called the bumblebee bat,
is the world's smallest bat and also the world's smallest
mammal! It lives in Thailand and Myanmar. It weighs
less than a tenth of an ounce (less than a penny) and is
only about one inch long!
Make a prediction for the wingspan of Kitti's hog-nosed bat.

dont trust me im no expert these losers made me fail a test bro this sucks

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
