3.5t+21=7     Distribute the 3.5 in the parenthesis
3.5t= -14       Subtract 21 from both sides
t= -4              Divide 3.5 from both sides.

A because when you distribute you get 3.5t + 21 = 7. Then subtract 21 from both sides to get 3.5t = -14. Then divide both sides by 3.5t to get -4.

\sqrt[8]{48^4}  can be rewritten as 48^4 to the \frac{1}{8}  power:

(48^4)^ \frac{1}{8}

Now, applying exponent rules (multiply exponent inside parentheses by the one outside parentheses), we get:

(48^ \frac{1}{2})

This is equivalent to \sqrt{48}, so now, we just simplify:

\sqrt{48}=  \sqrt{16*3}= \sqrt{16}* \sqrt{3}=4 \sqrt{3}

So:

\sqrt[8]{48^4} =4 \sqrt{3}

The number 2.2360667… is a __ because it cannot be written as a fraction(ratio)
den301095 [7]

in our number " 2.2360667…" the 3 dots mean that the digits keep going forever,  so we conclude that our number belongs to the set of irrational numbers.

<h3>Which type of number is 2.2360667…?</h3>

We will define two types of numbers:

Rational numbers: Are these that can be written as the quotient of two integers.

Irrational numbers: Can't be written as the quotient of two integer numbers, A rational number always has an infinite number of digits after the decimal point, and there is no pattern in these digits.

Now, in our number " 2.2360667…" the 3 dots mean that the digits keep going forever, that is enough to conclude that our number belongs to the set of irrational numbers.

The area of the square as a function of radius is given as  A(r) = 2r^2

As given in the question a square is inscribed in a b. So the diagonals of the square will be the diameter of the circle.

The formula for the diagonals of the square is,

                           D = s√2        

                         Where, s = side of the square

And the formula for the diameter of the circle is,

                              D = 2r

                       Where r = radius of the circle

As,     Diagonals of the square = Diameter of the circle

Thus,      s√2 = 2r

                s = 2r/√2

                 s = r√2            (1)

Now, the formula of the area of the square is,

                    A = s^2

Putting the value of s from equation (1) in the above formula we get

                 A = (r√2)^2

                A = 2r^2

Hence the area of the square as a function of radius is given as  A(r) = 2r^2
