Answer:
Step-by-step explanation:
We want to find the equation of a quadratic function in factored form with zeros at <em>x</em> = -4 and <em>x</em> = 0 that passes through the point (-3, 6).
The factored form of a quadratic is given by:
Where <em>p</em> and <em>q</em> are the zeros and <em>a</em> is the leading coefficient.
Since we have zeros at <em>x</em> = -4 and <em>x</em> = 0, let <em>p</em> = -4 and <em>q</em> = 0. Substitute:
Simplify:
And since we know that the function passes through the point (-3, 6), f(x) = 6 when <em>x</em> = -3. Thus:
Simplify:
Thus:
So, our quadratic function is:
Answer:
1 5/11 ≈ 1.455
Step-by-step explanation:
The total number of vehicles owned is
(4×0 + 8×1 + 6×2 + 4×3) = 32
The total number of families is ...
4 + 8 + 6 + 4 = 22
Then the mean number of vehicles per family is ...
32/22 = 16/11 ≈ 1.455
Answer:
136=x
Step-by-step explanation:
When an angle is shown, the one opposite of it is equal to the forst equation. The bottom angles are equal to 360ñ so if you take 46x2=92. Subtract 92 by 360 to get 268. Divide it by 2 to get one of the bigger angles, which is 134 degrees. And as for the top, one angle on the bottom is equal to the same spot on the top. so, 136=x

Answer:
Step-by-step explanation:
Let X be the first number.
(X)*(X+2)*(X+4)*(X+6) = 62985
(X^2 + 6X)^2 + 8(X^2 + 6X) = 62985
X = 13, AND X= -19
A. X = 13
(13)(15(17)(19) = 62985
B. X = -19
(-19)(-17)(-15)(-13) = 62985
