Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

the function f(r) givens the area of a circle with radius r.

i.e.

f(r)=3.14r^2

Put the value of r = 4 as we have to find the value of f(4) .

f(4)=3.14\times (4)^2\\\\f(4)=50.24

Hence, Option 'A' is correct.

Is it true or false that a bbinomial can have a degree of zero?
Mumz [18]

No, because any real valued term with degree 0 would be a constant. All constants in an expression can be combined into single term. Therefore if the expression were of degree 0, all the terms would be constants and could be combined into a single term making the expression a monomial.

Given the equation 2 Square root of x minus 5 = 2, solve for x and identify if it is an extraneous solution.
leonid [27]
<span>2 square root (x - 5) = 2. 2^2 (x -5) = 2^2. 4(x - 5) = 4. 4x - 20 = 4. 4x = 24. x = 6. This solution is not extraneous, because extraneous solutions emerge from solving the problem but are not actually valid solutions for the initial problem. With rounding, this solution is valid for the initial problem.</span>
