Answers
Answer:
The winning time increased by an average of 0.4 second per year from year 2 to year 4.
Step-by-step explanation:
I just took the quiz
The winning time for a race displayed in the table would be:
A). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.
Find the increase in winning time:Given that,
Year Winning Time(seconds)
1 27.5
2 28.4
3 28.7
4 29.2
5 29.44
The total change in the time = (0. + 0.3 + 0.5 + 0.24)/4
= 0.485 seconds
If we round off, it becomes 0.5 seconds.
Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.
Thus, option A is the correct answer.

The image of the point M is M' = (10, 7) as shown in the graph below.
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.
As per the given data:
Coordinates of point M = (-10, -7)
Rotation to be given = 180° (counter - clockwise)
For drawing the image of point M (-10, -7):
Step 1: Create a line connecting the origin to the point M (-10, -7) and extending across the third and first quadrants.
Step 2: Modify the x and y coordinates signs to reflect the 180° rotation, then mark the point in the first quadrant.
The image of the point M is M' = (10, 7) as shown in the graph below.
Hence, the image of the point M is M' = (10, 7).

A rectangle has length of 80cm and a width 50cm. And a scale factor of 3.5 what is the area in square cm of the dilated rectangle
Answers
Answer:
49,000 square cm
Step-by-step explanation:
To get the area of the dilated rectangle, we need the dilated dimensions
We simply multiply the scale factor by the dimensions
we have this as;
3.5 * 50 = 175 cm
and
3.5 * 80 = 280 cm
The area of the dilated rectangle is thus;
280 * 175 = 49,000 cm^2

Reflection of coordinate pointsReflection of any coordinates are mirror images of each other.
The reflection rule of the coordinate over the x-axis is given as:
(x, y) -> (x , -y)
Using the coordinate (-1, 2) on the image on the left and (5, 1) for the coordinate on the right.
Reflecting (-1, 2) over the x-axis is (-1,-2). In order to determine the translation used from (-1, -2) to (5, 1)
(-1+x, -2+y) = (5, 1)
-1 + x = 5
x = 6
-2 + y = 1
y =3

A jacket sells for $24.99. All the merchandise in the store is on sale at a 25% discount. If the sales tax is 8%, what will a customer pay for the jacket?
Answers
Answer:
$20.24
Step-by-step explanation:
Since the 25% discount takes off a quarter of the price, we multiply 24.99 by 3/4
24.99 x 3/4 = 18.74
So with the discount and without tax, the cost of the jacket is 18.74
Then we add 8% for sales tax
8% of 18.74 is $1.50
18.74 + 1.5 = 20.24
So the final cost of the jacket is $20.24
