Answer:
A. 120 cubic meters
Step-by-step explanation:
Measurements in volume use <em>cubic</em><em> </em>units which deals with 3 dimensions
You are a <em>regular </em>polygon. You may have any number of sides more than 3 .
By the way ... it's not necessary to say that all sides are congruent AND
all angles are too. If either condition is true, then the other one is true.
Answer:
Step-by-step explanation:
We have been given the equation
Take square root both sides. When ever we take square root, we include plus minus sign
Now, subtract 6 to both sides of the equation
Divide both sides by 5
In decimal we have
Answer:
39 feet
Step-by-step explanation:
In this problem, the height of the football at time t is modelled by the equation:
where:
s = 3 ft is the initial height of the ball
v = 48 ft/s is the initial vertical velocity of the ball
is the acceleration due to gravity (downward)
Substituting these values, we can rewrite the expression as
Here we want to find the maximum height reached by the ball.
This is equivalent to find the maximum of the function h(t): the maximum of a function can be found requiring that the first derivative of the function is zero, so
Calculating the derivative of h(t), we find:
And imposing it equal to zero, we find the time t at which this occurs:
And substituting back into h(t), we can find the maximum height of the ball:
The answer is b for your question
