199.

the z score for the 90th percentile is 1.28, so you can solve the equation

$\frac{x-180}{15} = 1.28$

which gets you the 199

Find the area A of the sector of a circle of radius 50 feet formed by the central angle

kozerog [31]

Answer:

$A=6250\ feet^2$

Step-by-step explanation:

Given that,

The radius of circle, r = 50 feet

The central angle, $\theta=5\ radian$

We need to find the area of the sector of a circle. The formula for the area of sector is given by :

$A=\dfrac{1}{2}r^2\theta\\\\=\dfrac{1}{2}\times 50^2\times 5\\\\A=6250\ feet^2$

So, the area f the sector of the circle is $6250\ feet^2$ .

What are the zeros of the graphed function y = (x + 3)(x + 5)?

tensa zangetsu [6.8K]

Y=(x+3)(x+5)
0=(x+3)(x+5)
0=x+3
Subtract three on both sides
-3=x
0=x+5
Subtract five on both sides
-5=x
So, -3 and -5 are the zeros of the graphed function.
Hope I helped!
