Jordan spent 22% of his time doing math homework. If hw spent 11 minutes on his math homework. How many minutes did he spend on
1 answer:
Jordan spends 50 minutes on his homework.
Step-by-step explanation:
Given,
Time spent on Maths homework = 11 minutes
This represents the 22% time of his total homework.
Let,
x be the total time spent on homework.
22% of x = 11
Dividing both sides by 0.22
Jordan spends 50 minutes on his homework.

So, the x-intercepts are

The vertex will be a minimum because the coefficient of is positive.
The x-coordinate of the vertex is
Substituting this back into the function, we get
So, the coordinates of the vertex are
<u>Part C</u>
Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.
The graph is shown in the attached image.
Answer:
c 1/2
Step-by-step explanation:
You are incorrect.
We are going from ABCDEFGH to A'B'C'D'E'F'G'H'. We are going from the large octagon to the small octagon. The scale factor of a dilation is the number you multiply the original lengths to get the lengths of the dilation.
Look at point (6, 0) which becomes (3, 0) in the dilation.
The distance from the origin to (6, 0) is 6 units.
The distance from the origin to (3, 0) is 3 units.
scale factor = dilated/original = 3/6 = 1/2
The scale factor of the dilation is 1/2.
Also look at segment AB whose length is 4. The length of segment A'B' is 2.
scale factor = dilated/original = 2/4 = 1/2
Answer: 1/2
