Answer:
80 square yards
Step-by-step explanation:
We know we have a width of 8 yards and a perimeter of 36.
how I figured it out was:
36=(8*2) * (x*2)
8*2=16
36-16=10
So now we know the length and width.
area of a rectangle is lw (length * width)
10*8=80.
Answer: Pretty sure it is 3

Answer:
<u>y = 6 x=8</u>
Step-by-step explanation:
(3х + 5y = 54)-2 times by -2
6х +4y = 72
-6х + -10y = -108 now combine the equations
6х + 4y = 72
-6y = -36 now divide
y = 6
Plug 6 in 6х +4 * 6 = 72
x=8

<em>Last option </em>
![f(t)=sin(\pi(t -3)) + 4](https://tex.z-dn.net/?f=f%28t%29%3Dsin%28%5Cpi%28t%20-3%29%29%20%2B%204)
Step-by-step explanation:
The general sine function has the following form
![y = Asin(bt-\phi) + k](https://tex.z-dn.net/?f=y%20%3D%20Asin%28bt-%5Cphi%29%20%2B%20k)
Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.
is the period: time it takes the wave to complete a cycle.
k is the vertical displacement.
phase shift
We know that:
amplitude: 1; period: 2; phase shift: 3; vertical shift: 4
Thus:
![A =1](https://tex.z-dn.net/?f=A%20%3D1)
![\frac{2\pi}{b}=2](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%7D%7Bb%7D%3D2)
![b=\pi](https://tex.z-dn.net/?f=b%3D%5Cpi)
![\phi=3](https://tex.z-dn.net/?f=%5Cphi%3D3)
![k=4](https://tex.z-dn.net/?f=k%3D4)
Then the function is:
![f(t)=sin(\pi(t -3)) + 4](https://tex.z-dn.net/?f=f%28t%29%3Dsin%28%5Cpi%28t%20-3%29%29%20%2B%204)
The answer is last option
Answer: I’m pretty sure it’s 4.50%
Step-by-step explanation:
Well when you divide the number (1.045) by 100 you get 4.5 and so 4.5 of 1500 would give you the balance.
