Answer:

A. $\frac{5}{6}\pi x^2$

Step-by-step explanation:

Central angle of shaded part

$\theta = 360\degree-60\degree= 300\degree$

Radius (r) = x unit

Area of the shaded part of $\odot K$

$= \frac{\theta}{360\degree} \times \pi r^2$

$= \frac{300\degree}{360\degree} \times \pi x^2$

$= \frac{5}{6}\pi x^2$

Write the equation of a line in standard form that passes through (-2, 5) and is perpendicular to

sdas [7]

Answer:

Step-by-step explanation:

x - 2y = 8

Write this in y = mx +b form

- 2y = -x + 8

Divide the equation by (-2)

$\dfrac{-2y}{-2}=\dfrac{-x}{-2}+\dfrac{8}{-2}\\\\\\y =\dfrac{1}{2}x-4$

Slope = 1/2

The slope of the perpendicular line = -1/m

$=\dfrac{-1}{\dfrac{1}{2}}=1*\dfrac{-2}{1} = -2$

m = -2 , ( -2 , 5)

Equation: y = mx +b

Plug in m = -2 ,x = -2 and y =5

5 = (-2)*(-2) + b

5 = 4 + b

5 - 4 = b

b = 1

Equation of the line:

y = mx +b

y = -2x + 1

Need to use the properties of exponents to solve this equation. I'm a bit confused on how to do this problem so a step by step d

garik1379 [7]

Answer:

Step-by-step explanation:

The given expression is

(4×10^8)(4×10^-7)/(4×10^8)

Considering the property of exponents which is expressed as

y^a × y^b = y^(a + b)

Applying the above rule to the denominator of the given expression, it becomes

4×10^8 × 4×10^-7 = 16 × 10^(8 + - 7)

= 16 × 10^(8 - 7)

= 16 × 10 = 160

The expression becomes

16 × 10/(4×10^8)

We would apply the property of exponents which is expressed as

y^a ÷ y^b = y^(a - b)

It becomes

16/4 × 10^(1 - 8)

= 4 × 10^-7
