Answer:
The perimeter is 
Step-by-step explanation:
we know that
The perimeter of the figure is equal to the circumference of a semicircle
plus the perimeter of a square minus the diameter of the circle
so

we have



The diameter of the circle is equal to the length side of the square
substitute

Step-by-step explanation:
Answer: The velocity of the ball is 108.8 ft/s downwards.
Step-by-step explanation:
When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:
g = 32 ft/s^2
To get the velocity equation we need to integrate over time, to get:
v(t) = (32ft/s^2)*t + v0
where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)
Because it is dropped, the initial velocity is equal to zero, then we get:
v(t) = (32ft/s^2)*t
Which is the same equation that we can see in the hint.
Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:
v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s
The velocity of the ball is 108.8 ft/s downwards.
Answer: y=mx+b
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. y=mx+b
We add the two times, 2 1/2 hours and 4 1/4 hours, together, and we get 6 3/4. ( 1/2 = 0.50, and 1/4 = 0.25, so 0.50 + 0.25 = 0.75. 0.75 = 3/4).
54 / 6 3/4 = 8.
