Answer: Peyton should be correct.
Step-by-step explanation: I took the quiz.
Step-by-step explanation:
solution,
given
DF = 42
DE = 7x+1
EF = 4x-3
DE = ?
here,
or, DF = DE +EF
or, 42 = 7x+1+4x-3
or, 42 = 11x-2
or, 42+2 = 11x
or, 44/11 = x
or, 4 = x
then,
replacing value of x in DE
DE = 7x+1
= 7*4+1
= 28+1
= 29
If you meant to write
, then using a calculator in radian mode would show ![\cos^{-1}(0.75) \approx 0.722734](https://tex.z-dn.net/?f=%5Ccos%5E%7B-1%7D%280.75%29%20%5Capprox%200.722734)
Rounding to the nearest hundredth gets us ![\cos^{-1}(0.75) \approx 0.72](https://tex.z-dn.net/?f=%5Ccos%5E%7B-1%7D%280.75%29%20%5Capprox%200.72)
Lower temperatures mean more cars sold
