Answer:

[-5, 5]

Step-by-step explanation:

The range of the sine function is [-1, 1].

If we multiply the sine function by-5, the resulting range is [-5, 5], which is found by multiplying each element of [-1, 1] by -5.

A credit card issuer offers an APR of 15.83% and compounds interest daily.

Romashka-Z-Leto [24]

Answer:

C. Its APR, because it's less than its effective interest rate.

Step-by-step explanation:

The interest rate determines the money you must pay on the outstanding balance on the credit card.

The credit card company would advertise the lowest numbers it could truthfully use.

The APR is 15.83 %.

The formula for the effective interest rate is

$i = \left (1 + \dfrac{r}{n} \right )^{n} - 1$

where the interest rates are expressed as decimals.

If the APR is 15.83% and the interest is compounded daily,

$\begin{array}{rcl}i & = & \left (1 + \dfrac{0.1583}{365} \right )^{365} -1\\\\ & = & (1 + 0.0004337)^{365} -1\\ & = & (1.0004337)^{365} -1\\ & = & 1.1715 - 1\\& = & 0.1715\\& = & 17.15 \%\\\end{array}\\\text{The effective interest rate is $\mathbf{17.15 \%}$}$

The APR is less than the effective interest rate, so that's what the company would advertise.

Answer: Divide both sides by 2 and apply square root (both sides).

Step-by-step explanation:

Hi, to answer this question we have to analyze the expression given:

2x²=200

A more simple way to solve the expression:

First, we have to divide each side by 2:

2x²/2=200/2

x²=100

Square root on both sides:

√x²=√100

x = -10 and 10

{-10;10}

Feel free to ask for more if needed or if you did not understand something.
