Answer:
All the real numbers.
Step-by-step explanation:
We have that x≥-1 or x<2.
The 'or' means that it can be one value or another: [-1, +∞) U (-∞, 2) = ℝ. Then, the solution to the compound inequality is All the real numbers. In set notation: ℝ.
You're going to use cross multiplication.
1 gal x 21 miles = 25miles x x
21 miles = 25x
Divide each side by 25 to get x alone
21/25 = 0.84, which is your x value.
Y+2=2(X-0) OR Y-6=2(X-4). Either one works.
Answer:
Sin(Ф) = Opposite / Hypotenuse
We know that Opposite = 6, and
Hypotenuse = 3/4 or 0.75
So,
Sin(Ф) = 6 / 0.75
Sin(Ф) = 8
So the value of sin of Ф would be 8

Dh/dt = -32t + 24
-32t + 24 = 0 when maximum
32t = 24
t = 24/32
t = 3/4
To find the maximum height just substitute "t" in
h = -16 (9/16) + 24(3/4) + 7
h = -9 + 18 + 7
h = 16ft
