Answer:
Step-by-step explanation:
I don't know if you are a calculus student, but since calculus is the easiest way to solve this, that's what I used. The position equation is

and the velocity function, the first derivative, is

From Physics, you should know that the velocity of an object is 0 at its highest point. That means that if we sub in a 0 for the velocity and solve for t, we find the time at which the object is at its highest point. That is:
and

By the Zero Product Property,
-12 definitely does not equal 0, so that means that
t - 2 = 0 and
t = 2 seconds.
So at 2 seconds, the object is at its highest point. Go back to the position function now and sub in a 2 for t to find the height of the object at 2 seconds.
so
s(2) = 38 meters

Answer:
D = 
Step-by-step explanation:
given R =
multiply all terms on both sides to eliminate the fraction
3R = 3D - T ( add T to both sides )
3R + T = 3D ( divide both sides by 3 )
D = 
The product of 1 and the number x is 1x and 4 less than this would be [x-4]

Answer:
The value of x = 8.1 units
Step-by-step explanation:
<em>Note: I am assuming we have to determine the value of the side 'x'.</em>
Given
Angle Ф = 32°
To determine:
x = ?
Using the trigonometric ratio
tan Ф = opposite / adjacent
here
Ф = 32°
opposite to angle 32° = x
adjacent to angle 32° = 13
Therefore,
substituting adjacent = 13, Ф = 32°, opposite = x in the equation
tan Ф = opposite / adjacent


x = 8.1 units tan 32° = 0.62
Therefore, the value of x = 8.1 units
