Answer:
44 ft
Explanation:
Perimeter of rectangle: 2(Length + Width)
Here given:
Perimeter: 2(L + W) = 2(14 + 8) = 2(22) = 44 ft
Answer: 8400 $
Explanation:
His original debt: money paid for 10 months + remaining debt
Assume X is his original debt
Then X= 10 • 150 + 6900
X= 1500+6900=8400$
| x+5 | refers to the absolute value of x+5, which means it is always positive and f(x) is like y, its a variable
so f(-7) means you sub -7 into x in the function, you get
f(-7)= | -7+5 | + (-7) + 5 = |-2| -2 = 2-2= 0
Try this solution (note, this is not the only way):
Q1: if sin(x- 3pi/2)=-sin(3pi/2- x)=--cosx=cosx, then sin(x- 3pi/2)=cosx and sin(x- 3pi/2)=<u>7/25</u>.
Q2: if tan(x)=√3 and x∈(180°;270°), then x=arctan√3+180°=60+180=240°.
If x=240°, then sin(x-210°)=sin30°=<u>0.5</u>.
