<u>Answer</u>

C. 16 feet

<u>Explanation</u>

The area of a circle is given by the formula:

Area = πr² Where r is the radius of the circle and π = 3.1416

201.0624 = 3.1416 × r²

r² = 201.0624/3.1416

= 64

r = √64

= 8 feet

Diameter is twice the radius.

∴ diameter = 2r

= 2 × 8

= 16 feet

Answer:

x¹²,8x⁴,6x,2x,1

Step-by-step explanation:

x²×x⁶×x⁴=x¹²

x^4(8) =8x⁴

x^1(6) =6x

x^1(2) =2x

x^0 = 1

the area of a rectangle garden is 38 1/4 square meters.The width of the garden is 4 1/2 meters.Find the length of the garden.

never [62]

Area = 38 1/4 = 153/4

Width = 4 1/2 = 9/2

Area = Length x Width

Length = Area/Width

So divide both of them:
$\sf{ \frac{153}{4} \div \frac{9}{2} =\sf{ \frac{153}{4} \times \frac{2}{9} = \frac{9 \times 17}{2\times 2}\times \frac{2}{9} = \frac{17}{2}$

So the length is equal to $\boxed{\sf{\frac{17}{2}}}$

Keshawn is asked to compare and contrast the domain and range for the two functions.

Lapatulllka [165]

Answer: The correct option is 'The domain of both functions is all real numbers'.

Step-by-step explanation:

Here, functions are f(x) = 5x and g(x) =5x

Since the domain of f(x) is, D= { x : x belongs to all real numbers.}

Therefore, Domain of f(x) is all real numbers.

Since f(x) and g(x) have the same value,

Therefore, Domain of g(x) is also the set of real numbers.

Now, range of f(x) is , R= { 5x : x belongs to all real numbers.}

Therefore, Range of f(x) is all real numbers.

⇒ Range of g(x) is also all real numbers.

So, we can say by the above explanation, only option (1) is correct.
