Answer:
B. 60=(4x-20)
Step-by-step explanation:
They are the same degree so they must equal eachother
Answer:
h = 10sin(π15t)+35
Step-by-step explanation:
The height of the blade as a function f time can be written in the following way:
h = Asin(xt) + B, where:
B represets the initial height of the blade above the ground.
A represents the amplitud of length of the blade.
x represents the period.
The initial height is 35 ft, therefore, B = 35ft.
The amplotud of lenth of the blade is 10ft, therefore A = 10.
The period is two rotations every minute, therefore the period should be 60/4 = 15. Then x = 15π
Finally the equation that can be used to model h is:
h = 10sin(π15t)+35
A more explained answer to show your teacher that you know the material and are not cheating is to multiply 350 by 2.5. this is the equivalent of 2.5 gallons, and 350x2.5 is 350x2+350x.5=700+175=875 sq feet that 2.5 gallons will cover
1.
By given conditions, we have:
![2y\leq 12\\\implies y \leq \frac{12}{2} \\\implies y\leq 6](https://tex.z-dn.net/?f=%202y%5Cleq%2012%5C%5C%3C%2Fp%3E%3Cp%3E%5Cimplies%20y%20%5Cleq%20%5Cfrac%7B12%7D%7B2%7D%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Cimplies%20y%5Cleq%206)
Range of $y$ is $y \in (-\infty , 6]$
2.
$32x^2y-8yz^2$
$= 8y(4x^2-z^2)$
$=\boxed{8y(2x-z)(2x+z)}$
