Answer:
In words the answer is between t=0 and t=2.
In interval notation the answer is (0,2)
In inequality notation the answer is 0<t<2
Big note: You should make sure the function I use what you meant.
Step-by-step explanation:
I hope the function is h(t)=-16t^2+32t because that is how I'm going to interpret it.
So if we can find when the ball is on the ground or has hit the ground (this is when h=0) then we can find when it is in the air which is between those 2 numbers.
0=-16t^2+32t
0=-16t(t-2)
So at t=0 and t=2
So the ball is in the air between t=0 and t=2
Interval notation (0,2)
Inequality notation 0<t<2

Step-by-step explanation:
sin 66.4 = opposite side / hypotenuse
sin 66.4 = 21.3 / y
y = 21.3 / sin 66.4
y = 23.24.
tan 66.4 = 21.3 / x
x = 21.3 / tan 66.4
x = 9.31.
Answer:
When 1 millimeter on the map is equivalent to 1 kilometer on the ground, the map scale is 1:100000.
Step-by-step explanation:
Answer:
pi x diameter
Step-by-step explanation:
To find the circumference of any given circle, multiply the radius by 2 to get the diameter, and then the diameter by pi (3.14)
So for this, you'll be using the pythagorean theorem to solve for the height.
Solve the exponents to get
Subtract 81 on each side to get
Square root each side, and your answer should be
or 13.23 ft
