Answer: 12 tables minimum, 15 max.

Step-by-step explanation:

If you substitute 14 in an inequality

200c + 500t >= 8800

200(14) + 500t and solve for t, you get t must be at least 12.

C +T cannot exceed 29

So figure 14 +12 =26 so they could sell up to 15 tables and not go over 29.

You will have to enter the t values 12,13,14,15

(09.05 MC) Derek kicks a soccer ball off the ground and in the air, with an initial velocity of 31 feet per second. Using the fo
ivann1987 [24]
In order to find the maximum of the function, we have to find the roots of the first derivative. 
H(t)=-16t^2+vt+s\\ H'(t)=-32t+v=0\\ v=32t\\ t=\frac{v}{32}=\frac{31}{32}=0.97s
This gives us the time at which the ball reaches its maximum height. 
We don't know s. We can find it because we know that at t=0 the ball is on the ground and its height has to be zero.
H(0)=0=-16(0)^2+v(0)+s\\ s=0
Finally, we can find the maximum height:
H(0.97)=-16(0.97)^2+31\cdot 0.97=15.0156 \simeq15$ft
The answer is C.

Express the area of a circle, a, as a function of its circumference, <br> c.
Naddika [18.5K]
Area = PI * radius^2

Circumference = 2 * PI * radius
radius = Circumference / 2 * PI

So, Area = PI * (Circumference / 2 *PI) * (Circumference / 2 *PI)
So, Area = Circumference^2 / (4*PI)
