Answer:

1). 113 unit²

2). 28 unit²

3). 22 unit²

Step-by-step explanation:

Given in the question Radius of the circle = 6 units and measurement of angle ACB = π/2

1). Area of the given circle = πr² = 3.14×(6)² = 3.14×36 = 113 unit²

2). Area of the sector created by ACB = 1/4×(area of the circle) = 1/4×113 = 28 unit²

3). Area of the shaded region of the circle = area of the sector created by ACB - area of the ΔDCE

= 28 - 1/2×3√(25-9)= 28 - 1/2×3×4 = 28 - 6 = 22 unit²

The expression 210,000\left(1.02\right)^x210,000(1.02)
Bad White [126]

Answer:

The house is increasing in value by 2% each year.

Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:

\frac{1.02-1}{1} *100 = 2\%

Step-by-step explanation:

For this case if we have this expression

210000(1.02)^x

We have the same functional forma like the exponential model given by:

y = a b^x

Where a = 210000 represent the constant or initial value and b = 1.02 represent the base.

So let's analyze the possible options:

The house has a starting value of 1.02.

False the starting value for this case is 210000 since if x=0 then we see that the value is 210000

The house is decreasing in value by 2% each year.

False the increase is 1.02 each year so then in % we have

\frac{1.02-1}{1} *100 = 2\%

We  have an increase of 2% each year

The house is increasing in value by 2% each year.

Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:

\frac{1.02-1}{1} *100 = 2\%

The value of the house is changing by 0.02% each year.

False the increase is 2% per year

Given y=(2x+3)2, choose the standard form of the given quadratic equation
katrin2010 [14]

y=(2x+3)^2 = 4x^2 +12x +9

Taking 4 out from first two terms, we will get

y=4(x^2+3x)+9

Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get

y=4(x^2+3x+\frac{9}{4}-\frac{9}{4})+9

Distributing 4

y=4(x+\frac{3}{2})^2+9-9

Cancelling 9

y=4(x+\frac{3}{2})^2

And that's the required standard form.
