Answer:
Roots is a fancy word for zero, which is also another fancy word for the x intercept.
You can factor a quad or use the quadratic equation to get zeros.
In this case, its non-factorable. So you gotta use the quadratic.
Using the quadratic equation you get : x = -2 ± √-1 (√5),
which can be rewritten as x = -2 ± i(√5)
Function was : x^2 + 4x + 9
For quad, I identified the following:
A = 1
B = 4
C = 9
I also added a picture of the formula in the attached.
Answer:
You always start with the parenthesis.

Answer:
The answer to your question is $79.38
Step-by-step explanation:
Data
base = 8.1 m
height = 3.5 m
cost = $2.80/ m²
Formula
Area of a parallelogram = base x height
Substitution
Area of a parallelogram = 8.1 x 3.5
= 28.35 m²
Total cost of the carpet
1 m² ------------------- $2.80
28.35 m² --------------- x
x = (28.35 x 2.80) / 1
x = 79.38 m²
J = 3S + 2
S = J - 14
S = 3S + 2 - 14
S - 3S = 2 - 14
-2S = - 12
S = -12/-2
S = 6
J = 3S + 2
J = 3(6) + 2
J = 18 + 2
J = 20
and the difference is : 20 - 6 = 14 <===
Answer:
65.97
Step-by-step explanation:
V = (pi)(r^2)(h/3)
V= (pi)(3^2)(7/3)
V = 65.97
