Answer: A) and B)
Step-by-step explanation:
So for the first one, a closed circle means that it includes the point and the graph proceeds in the positive direction. So it will be whatever number it starts on in the x axis is less than or equal to x.
The second one you find the distance it moves each second.
You do this by distance over time d/t. Then you divide the 408 by that number.
So 264cm / 11 seconds = 24 cm/sec
Then 408cm/ 24cm per sec = 17s
Answer:
A. 25/4
Step-by-step explanation:
= 25/4
To get the answer, first, you need to turn them into decimals
16 1/5 =16.2 and 5 2/5 =5.4
then all you need to do is to divide the numbers
16.2 divided by 5.4 equals to 3
so the answer is 3
Answer:
<u>a₂₀ = 60</u>
Step-by-step explanation:
<u>Given :-</u>
a₃ = 9
a₈ = 24
<u>To find :-</u>
a₂₀
<u>Solving :-</u>
Expand the given values.
a + 2d = 9 -(1)
a + 7d = 24 -(2)
Now subtract (1) from (2).
=> 5d = 15
=> d = 3
a = 9 - 2d
a = 9 - 6
a = 3
<u>Final answer :-</u>
a₂₀
= a + 19d
= 3 + 19(3)
= 3+ 57
= 60
<u>a₂₀ = 60</u>
