Answer:
y = 38
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the angles in the large outer triangle, then
x + 46 + 78 = 180
x + 124 = 180 ( subtract 124 from both sides )
x = 56
Consider the 3 angles in the smaller inner triangle, then
y + x + 86 = 180 , that is
y + 56 + 86 = 180
y + 142 = 180 ( subtract 142 from both sides )
y = 38

Step-by-step explanation:
If you have a calculator do pie times radius squared times height. So basically pie times 25 squared times 40
Answer:
a. y=7(x+0.5)^2+8.25
b. y=4(x+0.75)^2+0.75
c. the equation simplified is just f
d. f(f(x))=x^4+2x^3+4^2+3x+3

-8a-3b+6b-5a+9b= -13a-18b
-8a-5a=-13a
3b+6b+9b=18b
