Josh is a product designer for electrical company he designed a new table lamp Josh will use plastic to make the lamp he uses this formula to work out the amount of plastic needed P= b2 +2bh. the lenght of the base of the lamo will be 13cm the slope of the lamp will be 34cm. josh thinks the amount of plastic needed will be less than 1000cm2

Step-by-step explanation:

We can find the height using Pythagorean's Theorem.

So, the height is 31 centimeters, approximately.

Now, we use the given expression and the base and height

Therefore, Josh is right, he needs less than 1000 square centimeters. Specifically, he needs 975 square centimeters.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
