Calculate the average speed of the car in m/s

Mathematics
1 answer:
Alina [70]3 years ago
3 0

Answer:

14.4 m/s

Step-by-step explanation:

The speed of the car can be found by dividing the distance by the time. The distance is 0.8m 9 times or 0.8(9)=7.2 meters and the time is 0.5 seconds

s=\frac{d}{t} \\s=\frac{7.2}{0.5} \\s=14.4

I really need help plz
scoundrel [369]
The answer is choice A.

In this problem, we are shrinking the poster by 1/4 of its size.

Which means you need to divide the sides by 4
For width:
w =  \frac{32}{4}  = 8
For length:
l =  \frac{28}{4}  = 7

If pentagon ABCDE is rotated 180 degrees around the origin to create pentagon A’ B’ C’ D’ E’, what is the ordered pair of point
Naddik [55]
You haven't provided the original coordinates or the figure, therefore, I cannot give an exact answer. However, I will help you with the concept.

For rotation 180° about the origin, the signs of both the x any y coordinates are changed.
<u>This can be modeled as follows:</u>
(x,y) ......> rotation 180° about the origin ........> (-x,-y)

<u>Examples:</u>
(1,2) .......> rotation 180° about the origin ........> (-1,-2)
(2,-19) ....> rotation 180° about the origin ........> (-2,19)
(-3,-8) .....> rotation 180° about the origin ........> (3,8)
(-5,7) ......> rotation 180° about the origin ........> (5,-7)

Based on the above, all you have to do to get the coordinates of C' is change the signs of both the x and y coordinates

Hope this helps :)

Which of the following best describes the relationship between (x-2) and the polynomial 2x^3+x^2-3
pantera1 [17]
If (x - 2) is a factor of 2x³ + x² - 3 then for the value of x = 2 the polynominal is equal zero.
Substitute:
2 · 2³ + 2² - 3 = 2 · 8 + 4 - 3 = 16 + 4 - 3 = 17 ≠ 0
Answer: B) (x - 2) is not a factor.
