Answer:

Step-by-step explanation:

angle subtended by hour hand in 2 hours=360/12 *2=60°

\theta=\frac{\pi }{180}*60=\frac{\pi }{3}\\l=30~cm\\\theta=\frac{l}{r}\\\frac{\pi }{3}=\frac{30}{r}\\r=\frac{3}{\pi }*30=\frac{90}{\pi }\approx 28.65 ~cm

Answer the following questions
kolezko [41]

Answer:

56 m

Step-by-step explanation:

The area of a rectangle is found by multiplying length by width. since we already know the length, then we can just divide the total area by the length to find the width.

5432/97 = 56

and to check our work, make sure to multiply length by width.

97 * 56 = 5432

Determine the number of x-intercepts that appear on a graph of each function. f (x) = (x - 6)2(x + 2)2
Tpy6a [65]
<span>The number of x-intercepts that appear on the graph of  the function
</span>f(x)=(x-6)^2(x+2)^2 is two (2): x=6 (multiplicity 2) and x=-2 (multiplicity 2)


Solution
x-intercepts:
f(x)=0→(x-6)^2 (x+2)^2 =0

Using that: If a . b =0→a=0 or b=0; with a=(x-6)^2 and b=(x+2)^2

(x-6)^2=0
Solving for x. Square root both sides of the equation:
sqrt[ (x-6)^2] = sqrt(0)→x-6=0
Adding 6 both sides of the equation:
x-6+6=0+6→x=6 Multiplicity 2

(x+2)^2=0
Solving for x. Square root both sides of the equation:
sqrt[ (x+2)^2] = sqrt(0)→x+2=0
Subtracting 2 both sides of the equation:
x+2-2=0-2→x=-2 Multiplicity 2
