Answer:

9. Force is required to change an object velocity.Force is equal to mass times acceleration.

10. Force acting on object are paired with equal and opposite forces

Step-by-step explanation:

9.

Newton's 2nd law states that force is a product of mass and acceleration.In this case, the force of friction is causing deceleration of the ball.This is an example of rolling friction.Acceleration of the ball depends directly on this friction but indirectly on its mass.

10.

From Newton's 3rd Law ,for every action there is an equal and opposite reaction.The astronaut throwing the ball will experience the effect of an external force againts his own which is equal and in the opposite direction to the force she applied.This is why the astronaut moves backward but slower.

(13 POINTS+BRAINLIEST FOR FASTEST ANSWER!) find the areas of the trapezoids. please help me check my answers for both. thank you

Sunny_sXe [5.5K]

Answer:

1. 375

2. 294

Step-by-step explanation:

Area of a trapezoid

A = 1/2 (b1+b2) *h where b1 and b2 are the top and bottom of the trapezoide

1.

A = 1/2 (14+36) *15

= 1/2 (50)*15

= 25*15

375

A = 1/2 (21+7) *21

= 1/2 (28)*21

= 14*21

What are the zeros of the quadratic function f(x) = 6x2 + 12x – 7?

zalisa [80]

we have

$f(x) = 6x^{2} + 12x -7$

To find the zeros equate the function to zero

$6x^{2} + 12x -7=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$7= 6x^{2} + 12x$

Factor the leading coefficient

$7= 6(x^{2} + 2x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$7+6= 6(x^{2} + 2x+1)$

$13= 6(x^{2} + 2x+1)$

Rewrite as perfect squares

$13= 6(x+1)^{2}$

$(13/6)=(x+1)^{2}$

square root both sides

$x+1=(+/-)\sqrt{\frac{13}{6}}$

$x=-1(+/-)\sqrt{\frac{13}{6}}$

$x1=-1+\sqrt{\frac{13}{6}}$

$x2=-1-\sqrt{\frac{13}{6}}$

therefore

the answer is

The zeros of the quadratic function are

$x=-1+\sqrt{\frac{13}{6}}$ and $x=-1-\sqrt{\frac{13}{6}}$

Find coordinates of y = 4x^2+ 40x+112

vodomira [7]

Step-by-step explanation:

y = 4x²+ 40x+112 (:4)

x²+ 10x+ 28.

<u>28</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

1. |. 28

2. |. 14

4. |. 7

(x+4)(x+7)=0

x= -4. V. x= -7

Now fill in the x= -4 in y so you get the Y-coordinate and do the same for x= -7

Anseer should be like: 'The coordinates are (x, y) and (x, y)
