The dependent variable is the test grade. the constant or control variable is the algebra A1 course. the independent variable is if the test score changes.
If we call y the height of the plane, we know when the time (x) is 0, the height is 30000. So let's write that in:
y = 30000 + (0)
Then, for every increase of a minute (x increases by 1), the height reduces by 2000. This can be written as:
y = 30000 - 2000x
Using what we know about y = mx+c equations, the slope of the line is -2000, and the y-intercept is (0, 30000).
Answer:y=12.1244
X=24.2487
Step-by-step explanation:
SOHCATOA or you could have used Pythagorean theorem after you found one of the sides, but I find that it’s quicker to use this.
The vertical distance will be given by:
sinθ=opposite/hypotenuse
where:
θ=48°
opposite=h
hypotenuse=100 ft
thus
sin 48=h/100
hence
h=100 sin48
h=74.315 ft
Answer: 74.315 ft
