Answer:
181
Step-by-step explanation:
First, you need to find the value for g(10), that means that you have to substitute 10 in every x of g(x).
g(x)=x^2-10
g(10)=(10)^2-10
g(10)=100 - 10
g(10)= 90
Now that we have the value of g(10), we have to substitute in every x of f(x)
f(x)=2x+1
f(90) = 2(90) +1
f(90) = 180 +1
f(90) = 181
So the value of f[g(10)] is 181
B has two pre-images of -7 so it is not a function
Answer:
12 ft
Step-by-step explanation:
252π/7=36π, so r=6. d=r*2=12 ft
Answer:
C, 105 Degrees
Step-by-step explanation:
So the two opposite sides of a parallelogram is equal to each other and the two adjacent angles are supplementary. So if (x+40)+3x=180, this means that 4x+40=180. This gives us 4x=140, so x=35. If we plug it back into the equation it ascertains as such: 3(35)= 105. The answer for this question and angle O is 105 degrees, or C.
