Leo bought a used car for x dollars. one year later the value of the car was 0.88x. which expression is another way to describe
Lesechka [4]

Initial price of car = $x

After one year the price of car = $0.88x

to find the change in price we subtract the price after one year from initial price.

It means change in price = (x-0.88x)= 0.12x

By this we can easily see that , price dropped by 0.12

Or we can say that price dropped by 12%


So option C is the correct answer

C) 12% decrease

Set up, but do not evaluate, the integral that represents the length of the curve given by
netineya [11]

Answer:

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Step-by-step explanation:

Arc length of a parametric curve is:

L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt

x = t + cos t, dx/dt = 1 − sin t

y = t − sin t, dy/dt = 1 − cos t

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Or, if you wish to simplify:

L = ∫₀²ᵖⁱ √(1 − 2 sin t + sin²t + 1 − 2 cos t + cos²t) dt

L = ∫₀²ᵖⁱ √(3 − 2 sin t − 2 cos t) dt

Jeremy weigh a cell phone on a digital scale. write down 113 but forget to record the unit.which unit of measurement is correct
Andrew [12]
Hello! Grams would be the correct measurement. One kilogram is equal to about 2.2 pounds. If you cell phone weighed 113 kilograms it would be 249 pounds! The size of an adult!

One gram is about the weight of a paper clip, so it makes more sense for a cell phone to weigh 113 paper clips. 

I hope this helps!

In the new logo, what fraction of the parallelogram is shaded?
Harman [31]
D. 1/4 because imagine splitting that parallelogram in half, and you will see on the first half that half of that half is shaded. So that part is 1/2 and if you add the second half which isn't shaded at all, that's 0/2 so do 1/2 plus 0/2 and you will get 1/4
