If minor arc AB measures 9 inches, what is the length of the radius of circle C? If necessary, round your answer to the nearest

Art [367]

Complete Question

If minor arc AB measures 9 inches, what is the length of the radius of circle C? Where the radians is 0.75 radians

If necessary, round your answer to the nearest inch. 6 inches 12 inches 18 inches 24 inches

Answer:

12 inches

Step-by-step explanation:

The formula for Arc length =

Arc length = r θ

θ = 0.75

Arc length = 9 inches

Hence:

r = 9/ θ

r = 9/0.75

r = 12 inches

What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form? Quadratic formula: x = StartFraction neg

Harman [31]

Answer:

$x=\frac{-5(+/-)\sqrt{5}} {2}$

x = StartFraction negative 5 plus or minus StartRoot 5 EndRoot Over 2 EndFraction

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$f(x)=x^{2} +5x+5$

equate the function to zero

$x^{2} +5x+5=0$

so

$a=1\\b=5\\c=5$

substitute in the formula

$x=\frac{-5(+/-)\sqrt{5^{2}-4(1)(5)}} {2(1)}$

$x=\frac{-5(+/-)\sqrt{5}} {2}$

therefore

x = StartFraction negative 5 plus or minus StartRoot 5 EndRoot Over 2 EndFraction

: (3m−2)(2m+1)=0. Separate your answers, from smallest to greatest, with a comma. Enter only integers or fractions

sukhopar [10]

Answer:

-1/2, 2/3

Step-by-step explanation:

(3m - 2)(2m + 1) = 0

3m - 2 = 0 or 2m + 1 = 0

3m = 2 or 2m = -1

m = 2/3 or m = -1/2

Find the missing side of the right triangle using Pythagorean Theorem:

10^2 =8.7^2 +x^2;

x^2=100-75.69=24.31

x= sqrt 24.31~ 4.93

Area of trapezoid is area of triangle+area of a rectangle.

A=(8.7x4.93/2)+(12x4.93)

A=80.6055 ~81 ft^2
