Answer:
We can use the distributive property.
(x + 2)(y - 1)
= x(y) - x(1) + 2(y) - 2(1)
= xy - x + 2y - 2
In the standard form of the equation
![\\ \ f(t)=Acos[b(t\pm c)]+k\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%5C%20f%28t%29%3DAcos%5Bb%28t%5Cpm%20c%29%5D%2Bk%5C%5C%20%5C%5C%20)
The middle line =k
For our given problem
f(t) = 40cos (80t + 20)
On comparison we get k=0
Hence middle line=0
5 + (46 + 7) x 2
5 + (53) x 2
5 + 106

Answer:
115.2 in²
Step-by-step explanation:
Area of two triangles =
4 x 3 = 12
Area top rectangle/parallelogram =
5 x 8.6 = 43
Area back rectangle =
3 x 8.6 = 25.8
Area bottom rectangle =
4 x 8.6 = 34.4
Total = Sum of all areas
115.2 in²

Answer:
<h3>The answer is 5.7 %</h3>
Step-by-step explanation:
To find the rate given the principal , time and interest , we use the formula

where
p is the principal
t is the time
I is the interest
From the question
Principal = $1,250
Time = 4 years
Interest = $285
We have

We have the final answer as
<h3>5.7 %</h3>
