Answer: Balanced Force

Step-by-step explanation:

The rock is not moving, this means that the rock is not accelerated.

By the second Newton's law, we know that:

Force equals mass times acceleration.

Then if we do not have acceleration, means that the net force is equal to zero.

This happens when we have balanced forces, meaning that the normal force that does the rock when the man pushes it, is equal in magnitude but in opposite direction, so the net force is equal to zero.

What is two and two fourths plus one third
kkurt [141]

Answer:

2 5/6

Step-by-step explanation:

2 2/4 + 1/3

First, you have to make the bottoms of the fraction the same, by figuring out the lowest common denominator. In this case it would be 12. 4x3 = 12. 3x4 = 12.

Multiply the top number by the same number you multiplied the bottom by.

We multiplied the 4 by 3, so we would also multiply the 2 by 3 (which would be 6).

Do the same for the second fraction. 1x4 = 4.

Now we have 2 6/12 + 4/12. We add the top numbers together and we get 10/12.

Now we have to reduce the fractions. We can do this in this situation by just dividing the top and bottom numbers by 2.

Help me solve this question for geometry and thanks !!
Degger [83]

Answer:

(-2, -6)

Step-by-step explanation:

g(x) = (x+2)²-6

= x²+4x+4-6

= x²+4x-3

the vertex :

x = -4/2 = -2

y = (-2+2)²-6 =0-6 = -6

point of vertex : (-2, -6)

12=10(s+4)+50 what is the written problem to this can you help me with the answer
muminat

Answer:

s = -7.8

Step-by-step explanation:

from the question 12=10(s+4)+50

<u>first step</u>

open the bracket and evaluate for the value of s

12=10(s+4)+50

12 = 10s + 40 + 50

12 = 10s + 90

collect or combine the like terms

12-90 = 10s

-78 = 10s

divide both side by 10

-78/10 = 10s/10

-7.8 = s

therefor s = -7.8
