an object accelerates from rest to a velocity of 4.om / s over a distance of 20m . what was it's acceleration

1 answer:

7 0

Acceleration is the change in velocity over time. There's are formula's for such problems which are called kinematics equations. Look em up. One of them doesn't have t (time) in them you would normally use that one to solve this problem. 16/2/20=a=0.4m/s^2

I did it for you but please look it up, understand and memorize it ;)

What is the answer for 35/100+5/10?

valentinak56 [21]

First, get the common denominator. Do this by multiplying 5/10 by 10
35/100 + 50/100 = 85/100
Then,simplify :
17/20
Hope this helps!

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (16, -11)

Point (7, 0)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{0+11}{7-16}$
Add/Subtract: $m=\frac{11}{-9}$
Rewrite: $m=\frac{-11}{9}$

Write the slope - intercept form of the equation. PLEASE HELP. i will mark brainliest

cestrela7 [59]

Answer:

Step-by-step explanation: To find the equation of the perpendicular line, take the reciprocal of the slope with the opposite sign.

For example, the reciprocal of 4/3 is 3/4 and if it's negative, the opposite is positive.

The reciprocal of 2 is 1/2. and if it's positive, the opposite is negative.

The reciprocal of any number or fraction is whatever you multiply it by to get 1. 4 times 1/4 is 1 5/4 times 4/5 is 1. What about 1 ? 1 times 1 is 1. So one is its own reciprocal!

I hope this helps. (we're not supposed to give answers to t e s t s.)

The graph of the parent function f(x) = x3 is translated to form the graph of g(x) = (x − 4)3 − 7. The point (0, 0) on the graph

ella [17]

Answer: (4,-7)

Step-by-step explanation:

when f(x) = $x^3$ the vertex is (0,0). when g(x)= $(x-4)^3-7$ the vertex will be (4,-7). The equation is put into vertex form, in order for us to find the vertex (h,k), followed by $y=a(x-h)^3+k$ . With h=4 and k=-7.

Therefore, the answer is (4,-7)
