We have a quadratic expression:
[tex]\rm f(x)=-2x^2+28x+20[/tex]
Convert it to perfect square by perfect square trinomial:
[tex]\rm f(x)=-2(x^2+14x)+20[/tex]
[tex]\rm f(x)=-2(x^2+14x+49-49)+20[/tex] (adding and subtracting by 49)
[tex]\rm f(x)=-2(x-7)^2+2(49)+20[/tex]
[tex]\rm f(x)=-2(x-7)^2+118[/tex]
Here [tex]\rm (x-7)^2[/tex] is the positive term and -2 is the negative term so in order to get the highest weekly profit it should be zero, so
[tex]\rm -2(x-7)^2=0[/tex]
x = $7

The cost of shirts are 3 for $40.65 what is the unit cost per shirt?
Answers
Answer: $13.55 per shirt
Step-by-step explanation:
3 for $40.65
you must first divide 40.65 by 3 to find the cost of 1 shirt which the answer is $13.55. I hope this helps! Have a good day! :)
Since we are given the price of 3 shirts, we can work backwards to do $40.65 divided by 3 to get the unit cost per shirt, in which we get $13.55.
Glad to help!

Consider the graph given below. Determine which sequences of transformations could be applied to the parent function, f(x) = x, to obtain the graph above. Shift right 3 units, reflect over the y-axis, and then vertically stretch by a factor of 2 Shift left 2 units, reflect over the y-axis, and then vertically stretch by a factor of 6 Reflect over the x-axis, vertically stretch by a factor of 2, and then shift up 6 units Shift up 6 units, reflect over the x-axis, and then vertically stretch by a factor of 2 Reflect over the y-axis, vertically stretch by a factor of 2, and then shift up 6 units Shift left 3 units, reflect over the y-axis, and then vertically stretch by a factor of 2
Answers
The sequences of transformations that could be applied to the parent function are (e) Reflect over the y-axis, vertically stretch by a factor of 2, and then shift up 6 units
How to determine the sequence of transformation?The graph that completes the question is added as an attachment
From the attached graph, we have the following points
(3, 0) and (0, 6)
Calculate the equation of the line using
[tex]g(x) = \frac{y_2 - y_1}{x_2 -x_1} * (x - x_2) + y_2[/tex]
This gives
[tex]g(x) = \frac{6 - 0}{0 -3} * (x - 0) + 6[/tex]
Evaluate the quotient
g(x) = -2 * (x) + 6
Expand
g(x) = -2x + 6
This means that the equation of the line is:
g(x) = -2x + 6
So, we have:
f(x) = x as the parent function and g(x) = -2x + 6 as the transformed function.
The transformations from f(x) to g(x) are as follows:
Reflect over the y-axis i.e. f'(x) = -f(x) = -xStretch vertically by a factor of 2 i.e. f"(x) = 2f'(x) = -2xShift up by 6 units i.e. g(x) = f"(x) + 6 = -2x + 6Hence, the sequences of transformations that could be applied to the parent function are (e) Reflect over the y-axis, vertically stretch by a factor of 2, and then shift up 6 units

Suppose that the coordinates of point G were (4, –3) instead of (4, 3). Would the area of the triangle be the same? Explain why or why not.
Answers
The coordinate of point G is its location on the coordinate plane
The area of the triangle would not remain the same
How to determine the area statement?From the question, we have the following points
G = (4,-3) and
G = (4,3)
The above coordinates are two different points, and so they would make the triangle have different areas.
Hence, the area of the triangle would not remain the same

A gumball machine contains 232323 green gumballs, 525252 red gumballs, 343434 blue gumballs, 616161 yellow gumballs, and 303030 pink gumballs. What percentage of the gumballs are red?.
Answers
Answer:
%26
Step-by-step explanation:
We can set up a proportion to find out what percentage of the gumballs are red:
[tex]\frac{525252}{232323+525252+343434+616161+303030} =\frac{x}{100}[/tex]
[tex]\frac{525252}{2020200} =\frac{x}{100}[/tex]
[tex](525252)(100)=2020200(x)[/tex]
[tex]\frac{(525252)(100)}{2020200} =x[/tex]
[tex]26=x[/tex]
Since we set up x as a fraction of 100 when writing the proportion we can say that the percentage of red gumballs is %26.

1 book = $2.50
4 books = $10.00
1 bookmark = $1.95
