Find c.

Mathematics
1 answer:
Alexxx [7]2 years ago

9514 1404 393

Answer:

  14.9 cm

Step-by-step explanation:

To find c using the Law of Sines, you must know angle C. That is found from ...

  C = 180° -A -B = 180° -150° -12° = 18°

Then the law of sines tells you ...

  c/sin(C) = b/sin(B)

  c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)

  c ≈ 14.9 cm

Consider the function f(x) = x2 + 2x – 35. If one of the zeros of the
Whitepunk [10]

If one zeros is x= -7 then the other zero is x=5

Step-by-step explanation:

We are given the function: f(x) = x^2 + 2x-35

If one zeros of the function is x=-7 we need to find other zero of the function.

We can find zeros of the quadratic equation by factorizing the equation

f(x) = x^2 + 2x-35

Factorizing the quadratic equation:

x^2 + 2x-35=0\\x^2-5x+7x-35=0\\x(x-5)+7(x-5)=0\\(x+7)(x-5)=0\\x+7=0\,\,and\,\,x-5=0\\x=-7\,\,and\,\,x=5

So, if one zeros is x= -7 then the other zero is x=5

PLEASE HELP I REALLY NEED IT
Aleonysh [2.5K]

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.

Write and solve an equation to answer the question. 14 is what percent of 70?
slamgirl [31]

Answer:

20%

Step-by-step explanation:

An equation is 14=x/100*70 or 14=(x%)*70, either one works

solve for x:

  1. 14=x/100*70
  2. 14/70=x/100 (Divide each side by 70)
  3. 1/5=x/100 (Simplify 14/70)
  4. 100/5=x (Multiply each side by 100 to isolate x)
  5. x=20 (Simplify 100/5)
  6. 20% (Rewrite as a percent)

hope this helps!!
