Answer: y = k/9
Step-by-step explanation:
y <> x² and x = 3
Therefore,
y = k/3²
y = k/9
To find the average velocity in a velocity-time graph at a particular interval, simply determine the gradient at that particular interval.
<span>a. average velocity= 4/1 </span>
<span>= 4m/s </span>
<span>b. average velocity from 1 to 2.5s= 6/(2.5-1) </span>
<span>= 4m/s </span>
<span>average velocity from 2.5 to 4.0s= 0m/s </span>
<span>average velocity from 0 to 4.0s= (4+0)/4 </span>
<span>= 1m/s </span>
<span>c. average velocity from 1.0 to 4.0s= (4/3)m/s </span>
<span>average velocity from 4.0 to 5.0s= 2/1 </span>
<span>= 2.0m/s </span>
<span>average velocity from 1.0 to 5.0s= ((4/3)+2)/4 </span>
<span>= (5/6)m/s </span>
<span>d. average velocity from 0 to 4.0s= 1.0m/s </span>
<span>average velocity from 4.0 to 5.0s= 2.0m/s </span>
<span>average velocity from 0 to 5.0s= (1.0+2.0)/5 </span>
<span>= (3/5)m/s </span>
Answer:
100 ft squared
Step-by-step explanation: you would usually round up to the nearest whole number with these and 9.7 would round to 10 and 10 times 10 would be 100
Answer:
y = 3x+5
y = 3x+9
y = 3x+22
There are infinitely many ways to answer this
======================================================
Explanation:
Parallel lines have equal slopes, but different y intercepts.
So the answers will have y = 3x in them. We'll change the +2 to other values.
Pick 3 of your favorite numbers, as long as you don't pick the number 2.
I'll pick the numbers 5, 9 and 22
Three possible answers are:
y = 3x+5
y = 3x+9
y = 3x+22
All of those equations have a slope of 3, but different y intercepts so we are guaranteed to have parallel lines to the original y = 3x+2.
Answer:
D
Step-by-step explanation:
Using the midpoint formula to find the coordinates of Q
let the coordinates of Q = (x, y ), then
0.5(3 + x) = 2 ← equate to x- coordinate of M
Multiply both sides by 2
3 + x = 4 ( subtract 3 from both sides )
x = 1
and
0.5(9 + y) = 8 ← equate to y- coordinate of M
Multiply both sides by 2
9 + y = 16 ( subtract 9 from both sides )
y = 7
Thus the coordinates of Q are (1, 7 ) → D
