Suppose that x and y vary inversely, and x = 7 and y=11. Which function models the inverse variation?Answers:Y=1.57xY=77/xY=4/xY

sdas [7]

Answer:

Y=77/x

Explanation:

Y varies inversely with x meaning

$y\propto\frac{1}{x}$

adding a proportionality constant gives

$y\propto\frac{k}{x}$

Now, we are told that y = 11 and x = 7; therefore, the above gives

$11=\frac{k}{7}$

Solving for k gives

$k=77$

Therefore, the function that models the inverse variation is

$y=\frac{77}{x}$

which is our answer!

A stunt man wants to drive a car off a ramp at an angle of 35∘ from the ground. He already has a ramp with an angle of 15∘. He p

eduard

Answer:

The second ramp needs to have 25°.

Step-by-step explanation:

Required ramp angle for driving the car from the ground = 35°.

First ramp angle = 15°

Therefore, second ramp angle equals required ramp angle minus first ramp angle, which is = 35° - 15° = 20°

The 20° ramp angle will make the total ramp angle to be equal to 35°.

That is 15° + 20° = 35°
