Answer:
i believe its B
Step-by-step explanation:
Well, Brainly really doesn't like questions that are lifted straight out of exams, tests, or quizzes, so there's only so much I can say.
... You've GOT the formula for the height h at any time t .
... It TELLS you to find t when h=0.
... So write the equation
-16 t^2 + 32 t = 0
and then solve the equation to find t .
You'll find two solutions for t .
One of them is. t=0 .
This reveals the mind-blowing fact that the instant before the rocket was launched, at t=0, the rocket was on the ground.
The other solution for t will tell you how many seconds after launch the rocket is back on the ground.
1. We assume, that the number 25000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 25000, so we can write it down as 100%=25000.
4. We know, that x% equals 3700 of the output value, so we can write it down as x%=3700.
5. Now we have two simple equations:
1) 100%=25000
2) x%=3700
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=25000/3700
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 3700 is what percent of 25000
100%/x%=25000/3700
(100/x)*x=(25000/3700)*x - we multiply both sides of the equation by x
100=6.75675675676*x - we divide both sides of the equation by (6.75675675676) to get x
100/6.75675675676=x
14.8=x
x=14.8
now we have:
3700 is 14.8% of 25000
Answer:
The answer is y = - 7x + 6
Step-by-step explanation:
A parallel line will have the same slope and since the point that is given is a y intercept, you just plug in -7x + 6 to get your parallel equation
