Step-by-step explanation:
40(11.28)+6(11.28*1.5)
40(11.28)+6(16.92)
451.2+101.52
$552.72
(6.72×10^9)÷(3.2×10^2)=2.1×10^7
6.72÷3.2=2.1 and
10^9÷10^2=10^7 {here power is subtracted 9-2=7}
2.1×10^7
Answer:
<u>Step-by-step explanation:</u>
Use the vertex formula: y = a(x - h)² + k where
- a is the vertical stretch
- -a is a reflection over the x-axis
- (h, k) is the vertex
We can see that the vertex of the curve is (-3, 4) --> h = -3, k = 4
and it is a reflection over the x-axis --> a-value is negative
We need to find the a-value. Choose another point on the curve and plug it into the vertex formula for (x, y) and then solve for a.
I will choose (x, y) = (-3/2, 0)
Now that we know the vertex and the a-value, we can input them into the vertex formula:
in simplest form is
.
Because:
Divide the numerator (2) and denominator (50) by 2. Hope this helps!
