Answer:

Hey Hey here you go!

according to the chart thing y is the plane and x is hours

Question A- so the plane(y) goes 600 miles x hours. it says 600 per hour so 600 miles an hour.

Question B- the dependant vriable is 6 from 600. why? because it was the main source for the eqauation and we used it to subract 300 from to get the next answer.

Question C- 600 miles x 600 miles is 1,200 miles. wich would be 1,200 miles for two hours. it said two and a HALF hour so half of 600 is 300 so add that to 1,200 + 300 is 1,500 miles in 2.5 hours (two and a half hours.)

Step-by-step explanation:

I hope this helped!! Have a great dayyy

The quadratic function d= -4x+1,100 models a snowboarder's distance, in feet, from the bottom of a hill x seconds after the snow

Fynjy0 [20]

Answer:

16 seconds (Approximately)

Step-by-step explanation:

Given:

The function that gives the distance of snowboarder from the bottom of hill with time 'x' is:

$d=-4x^2+1100$

Final position of the snowboarder is $d=100\ ft$

Now, plugging in 100 for 'd' and solving for 'x', we get:

$100=-4x^2+1100$

Adding -1100 both sides, we get:

$100-1100=-4x^2+1100-1100\\-1000=-4x^2$

Dividing both sides by -4, we get:

$\frac{4x^2}{4}=\frac{1000}{4}\\x^2=250$

Taking square root and neglecting the negative root as time can't be negative. So,

$\sqrt{x^2}=\sqrt{250}\\x=5\sqrt{10}=15.8\ s\approx 16\ s$

Therefore, after 16 seconds, the snowboarder will be at a distance of 100 ft from bottom of hill.

Help me pls, BRAINEST AWARD

Natali [406]

Answer:

x = 3.7

Step-by-step explanation:

By applying sine ratio for the given angle B,

sin(39°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(39°) = $\frac{AD}{AB}$

0.6293 = $\frac{AD}{7}$

AD = 4.41

By applying tangent ratio for the given angle C,

tan(50°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

1.19 = $\frac{AD}{x}$

1.19 = $\frac{4.41}{x}$

x = 3.7
