Andrei [34K]4 years ago

Answer:

Perimeter = 63.9 cm.

Area = 166.96 cm^2 to the nearest hundredth.

Step-by-step explanation:

The perimeter = 16+20.9+27 = 63.9 cm.

To find the area you can use Heron's Formula.

Area = √ [ s(s-a)(s-b)(s-c)]  where  s = the semi-perimeter and a, b and c are the lengths of the 3 sides.

s = 63.9 / 2 =  31.95.

Area of the triangle = √ (31.95(31.95-16)(31.95-20.9)(31.95-27)]

 = 166.96 cm^2.

What is the approximate area, in square units, of the circle below
Dmitry [639]

Answer:

A) 50

Attached is the image of the figure.

Step-by-step explanation:

Area of a circle can be expressed as;

Area A = πr^2 ......1

Where;

r = radius

From the attached image, the shape is a Circle and the diameter of the circle is 8 units.

Diameter d = 8

Radius r = diameter/2 = 8/2 = 4 units

Substituting the radius into equation 1;

Area A = π × 4^2 = 16π

Area A = 50.265

Area A = 50 square units (approximately)

If g(x)=4x-6 then g^-1(x)=?<br> (1) -4x+6<br> (2)-1/4x+1/6<br> (3)1/4x+3/2<br> (4)1/4x+6
kati45 [8]

Given:

g(x)=4x-6

To find:

The function g^{-1}(x).

Solution:

we have,

g(x)=4x-6

Put g(x)=y.

y=4x-6

Interchange x and y.

x=4y-6

Isolate y.

x+6=4y

\dfrac{x+6}{4}=y

y=\dfrac{x+6}{4}

Substitute y=g^{-1}(x).

g^{-1}(x)=\dfrac{x+6}{4}

g^{-1}(x)=\dfrac{x}{4}+\dfrac{6}{4}

g^{-1}(x)=\dfrac{x}{4}+\dfrac{3}{2}

Therefore, the correct option is (3).
