The answer is :) mark brainliest please
Answer:
Step-by-step explanation:
rather than doing all of the sums, you should just learn the formula (for the pattern)
it is <u>n(highest + lowest)</u> where n is number of numbers
2
for example 2+3+4+5+6 = 20
<u>5(6+2)</u> = 20
2
~~~~~~~~~~~~~~~~~~~~
1+2+3+4+5+6+7+8 = 36
<u>8(9)</u> = 72/2= 36

Answer:
x = 30t cos 20 or x = 28.19t.
y = 30t sin 20 - 4.9t^2 + 2 or y = -4.9t^2 + 10.26t + 2.
Step-by-step explanation:
The horizontal component of the velocity = 30 cos 20 m/s so the distance at time t seconds = 30t cos 20.
The vertical component is obtained from the equation of motion
s = ut - 1/2* 9.8t^2 + 2
u = 30 sin 20
Vertical component = 30t sin 20 - 4.9t^2 + 2.
No because no matter what u multiply 7:5 u will never get 35:10, they are not equal<span />
