Hmmm the increase, wel is just the difference 367 - 312, which is 55.
now, if we take 312 to be the 100%, what is 55 off of it in percentage?
You use the slope formula to classify a quadrilateral as a parallelogram or rectangle. you use the distance formula to see if it is a trapezoid.
Answer:
27 =x
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the same side of the large triangle.
x+8 10
------- = -------------------
2x-5 14
Using cross products
14 (x+8) = 10 (2x-5)
Distribute
14x+112 = 20x-50
Subtract 14x from each side
14x-14x +112 = 20x-50-14x
112 = 6x-50
Add 50 to each side
112+50 = 6x-50+50
162 = 6x
Divide by 6
162/6 =6x/6
27 =x
Answer:
π
Step-by-step explanation:
The standard form of the sine function is
y = a sin(bx + c)
where a is the amplitude, period =
and
phase shift = - 
here b =
, c = - 
phase shift = - 
=
× 2 = π
