A slice of pizza whose edges form a 32degrees angle with an outer crust edge 4 inches long was found in a gym locker. What was t

liq [111]

Answer:

The diameter was $d=\frac{45}{\pi }$ in.

Step-by-step explanation:

The arc of a circle is given by

$s=r\theta$

where

s = arc length

r = radius of the circle

θ = measure of the central angle in radians.

From the information given

s = 4 in

θ = 32º

To find the diameter of the original pizza, we use the formula of the diameter of a circle

$d=2r$

First, we need to convert the angle to radians

$\theta=32\º \cdot \frac{\pi}{180\º} =\frac{8\pi }{45}$

Next, solve for r from the arc formula

$r=\frac{s}{\theta} =\frac{4}{\frac{8\pi }{45}} =\frac{45}{2\pi }$

Then, we use the diameter of a circle formula

$d=2r=2(\frac{45}{2\pi })=\frac{45}{\pi }$

The cost, C(x),for manufacturing x units of certain product Is given byC(x)=x^2-20x+35, find the units manufactured at a cost of

Rainbow [258]

Answer:

No units

Step-by-step explanation:

The cost function is given by;

$C(x)=x^2-20x+35$

To find the units manufactured at a cost of $5,560

We equate the C(x) to 5560 and solve for x.

$x^2-20x+35 = 5560$

$x^2-20x+35 - 5560 = 0$

$x^2-20x - 5525= 0$

The discriminant of this equation is negative.

That is,

$d = {( - 20)}^{2} - 4 \times 1 \times - 5560 \: < 0$

Hence the equation has no real roots.

This means no units can be produced at $5,560

Zak takes 3 steps for every 2 steps Rich takes. How many steps will zak take if rich takes 18 steps? Explain how you found the a

vodka [1.7K]

To solve this problem we can think of a rule of three.
Writing the rule of three we have:
3 ---> 2
x ----> 18
Clearing the value of x
x = ((18) / (2)) * (3) = 27
answer
zak will take 27 steps if rich takes 18 steps
