Step-by-step explanation:

Step 1: Write equation

-5 + x = 3

Step 2: Solve for <em>x</em>

  1. Add 5 to both sides: x = 8

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-5 + 8 = 3

Describe and correct the error a student made in writing an exponential function
NemiM [27]

Answer:

we CANNOT DIVIDE 3 with 6.

Step-by-step explanation:

Here,as given in the question:

Starting value = 6

Constant ratio = 1/3

Now, exponential function is obtained by the product of starting value and the constant ratio repeatedly.

⇒ f(x) = (Starting value) x (ratio)... x times

\implies f(x) = 6 (\frac{1}{3} )^x =  6 (\frac{1}{3} )  (\frac{1}{3} )  (\frac{1}{3} )  .... x  

Now, we CANNOT DIVIDE 3 with 6 as it is in the power of x.

Hence, \implies f(x) = 6 (\frac{1}{3} )^x and f(x)  \neq 2^x

What is the area of the shaded region in the given circle in terms of pi and in simplest form?
BartSMP [9]

Answer:

Area of the shaded portion = (120π + 36√3)sq. m

Step-by-step explanation:

Area of the shaded region = Area of circle - Area of triangle

Given

radius of the circle = 12m

Area of the circle = πr²

Area of the circle  = π(12)²

Area of the circle  = 144π m²

Area of the sector = theta/360 * πr²

Area of the sector =  60/360 * 12²π

Area of the sector = 60/360 * 144π  = 24π

Area of the triangle = 1/2 bh

Area of the triangle = 1/2 (12cos30)(12)

Area of the triangle = 36√3

Area of the shaded portion = (144π - 24π + 36√3)sq. m

Area of the shaded portion = (120π + 36√3)sq. m
