Answer:
A.
Step-by-step explanation:
If you put the x value of the table and use it in each equation, only one gives the y output on the table.
y=x + 4
5=1 + 4
6=2+4
7=3+4
8=4+4
9=5+4
C) 84
7(6x2)
Sry if it’s wrong
It should be 78.54.
Double check that.
Formula: V=πr2h/3
r2 is R squared
Answer:
Cubic polynomial has zeros at x=−1x=−1 and 22, is tangent to x−x−axis at x=−1x=−1, and passes through the point (0,−6)(0,−6).
So cubic polynomial has double zero at x=−1x=−1, and single zero at x=2x=2
f(x)=a(x+1)2(x−2)f(x)=a(x+1)2(x−2)
f(0)=−6f(0)=−6
a(1)(−2)=−6a(1)(−2)=−6
a=3a=3
f(x)=3(x+1)2(x−2)f(x)=3(x+1)2(x−2)
f(x)=3x3−9x−6
7 apples = 4.55
To find the single cost of an apple, divide 4.55 by 7
4.55/7 = 0.65 per apple
Let's check to see if this is right.
0.65 x 7 = 4.55 = correct
0.65 x 9 = $5.85 for 9 apples
