Step-by-step explanation:

First of all we need to know the formula for the circumference which is: $c=2\pi r$

We don't have the radius. What we only have is the area; therefore, we must use the area formula and extract the radius from it.

The formula for the area is: $A=\pi r^2$ Solve for r;

$r^2=\frac{A}{\pi}\\ r=\sqrt[]{\frac{A}{\pi} }$

$r=\sqrt[]{\frac{50.24inch^2}{3.14} }$

$r=\sqrt[]{16inch^2}\\ r=4inch$

Now that we've found the radius, we simply plug it into the circumference formula.

$C=2\pi r\\C=2(3.14)(4)\\C=25.12inch$

- Maya is playing golf. On her first two holes,

antiseptic1488 [7]

Answer:

Her score after the first two holes is 5 over par

Step-by-step explanation:

Calculating golf scores we have;

Maya's score on the first hole is one under par

Maya's score on the second hole is six over par

Therefore we have Maya's score after the first two holes is given as follows;

She took one less than her allotted shot for the first score and 6 more than her allotted shot for the second hole

Her gross score is 1 under par + 6 over par = 5 over par

Therefore, her score after the first two holes is 5 over par

When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.

For example:

$\frac{1}{y^{-2}} =\frac{y^2}{1}$ or $y^2$

$2x^{-3}$ or $\frac{2^1x^{-3}}{1} =\frac{2}{x^3}$

$\frac{1}{x^{-5}} =x^5$

When a base with an exponent is divided by a base with an exponent, you subtract the exponents together. (But you can only combine the exponents when the bases are the same)

For example:

$\frac{x^2}{y}$ (can't combine because they have different bases of y and x)

$\frac{x^5}{x^3} =x^{(5-3)}=x^2$

$\frac{2^2}{2} =2^{(2-1)}=2^1 = 2$

When you multiply an exponent directly to a base with an exponent, you multiply the exponents together.

For example:

$(x^2)^3=x^{(2*3)}=x^6$

$(y^2)^{10}=y^{(2*10)}=y^{20}$

$\frac{2e^0}{(e^{-3})^2}$ First multiply the exponents together in the denominator

$\frac{2e^0}{e^{(-3*2)}}= \frac{2e^0}{e^{-6}}$ Now subtract the exponents together

$2e^{(0-(-6))}$ (two negative signs cancel each other out and become positive)

$2e^{(0+6)}$

$2e^6$

4 x 0.15 Is the problem I'm stuck onnnnn please help me it'll make me happy

kupik [55]

Answer:

0.6

Step-by-step explanation:

4 × 0.15

I can't show how to do it by typing, but in order to solve this you multiply 4 by each of those numbers and add them up together.

If done correctly, it should equal 0.6 or 0.60 (they are the same number).
