Answer:
I think the answer would be b. Ariel, Amber, and Ethel because if you look at the vertical lines that are going up and down, you can count that there are 6 boxes colored in and that there are 4 left uncolored.
Step-by-step explanation:
The 6 boxes acts as the 60% and the 4 acts as 40%. If you add them together, you would get 100%. Ethel also has a horizontal line going down the center of his boxes, which makes his numbers doubled, but he still has 60% colored in. Ariel only has 5 boxes in total and 3 if them colored in, but the 3 are still 60% and the 2 uncolored are 40%. If you were to divide every box onto 2, you would end up with 10 in total, 6 colored in, and 4 uncolored.
Answer:
$395.61
Step-by-step explanation:
The formula for simple interest is:
![i=Prt](https://tex.z-dn.net/?f=i%3DPrt)
Where
i is the interest amount
P is the principal amount
r is the rate of interest per time period
t is the time period
Here,
P = 4869
we want to find after 30 months, that converted to years is:
30/12 = 2.5 years
t = 2.5
The annual rate is 3.25% = 0.0325
Now, substituting, we find our answer:
![i=Prt\\i=(4869)(0.0325)(2.5)\\i=395.61](https://tex.z-dn.net/?f=i%3DPrt%5C%5Ci%3D%284869%29%280.0325%29%282.5%29%5C%5Ci%3D395.61)
The interest earned is <u>$395.61</u>

The answer to your question is -1 < y < 3

The parabola represented by this graph has the following equation:
y = -16.67(x + 1)² + 2
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
A downward open parabola rises from (-2.4, 4) to (-1,2), and declines through (0.4, -4) on the coordinate plane, hence the vertex is given by:
(-1,2), hence the coefficients are h = -1 and k = 2, and the equation is:
y = a(x - h)² + k
y = a(x + 1)² + 2
We have that when x = -0.4, y = -4, hence the leading coefficient is found as follows:
y = a(x + 1)² + 2
-4 = a(-0.4 + 1)² + 2
a = -6/0.6²
a = -16.67
Hence the equation is:
y = -16.67(x + 1)² + 2
