Factor:<br> 4tan^2x-(4)/(cotx)+sinx(cscx) ...?

lisov135 [29]

4tan^(2)x-((4)/(cotx))+sinxcscx

Multiply -1 by the (4)/(cotx) inside the parentheses.

4tan^(2)x-(4)/(cotx)+sinxcscx

To add fractions, the denominators must be equal. The denominators can be made equal by finding the least common denominator (LCD). In this case, the LCD is cotx. Next, multiply each fraction by a factor of 1 that will create the LCD in each of the fractions.

4tan^(2)x*(cotx)/(cotx)-(4)/(cotx)+sin...

Complete the multiplication to produce a denominator of cotx in each expression.

(4tan^(2)xcotx)/(cotx)-(4)/(cotx)+(cot...

Combine the numerators of all expressions that have common denominators.

A quadratic function and an exponential function are graphed below. How do the decay rates of the functions compareover the inte

Kobotan [32]

To check the decay rate, we need to check the variation in y-axis.

Since our interval is

$-2We need to evaluate both function at those limits.At x = -2, we have a value of 4 for both of them, at x = 0 we have 1 for the exponential function and 0 to the quadratic function. Let's call the exponential f(x), and the quadratic g(x).[tex]\begin{gathered} f(-2)=g(-2)=4 \\ f(0)=1 \\ g(0)=0 \end{gathered}$

To compare the decay rates we need to check the variation on the y-axis of both functions.

$\begin{gathered} \Delta y_1=f(-2)-f(0)=4-1=3 \\ \Delta y_2=g(-2)-g(0)=4-0=4 \end{gathered}$

Now, we calculate their ratio to find how they compare:

$\frac{\Delta y_1}{\Delta y_2}=\frac{3}{4}$

This tell us that the exponential function decays at three-fourths the rate of the quadratic function.

And this is the fourth option.

How much money should be deposited today in an account that earns 8% compounded monthly so that it will accumulate to 13,000 tho

gladu [14]

Answer:

$10,234.31

Step-by-step explanation:

A suitable financial calculator or spreadsheet can evaluate the future value function for you. It will tell you that $10,234.31 must be deposited today to have $13,000 in three years, when interest is 8% compounded monthly.

You are solving for P:

13000 = P(1 +0.08/12)^(12×3)

P = 13000/(1 +0.08/12)^36 ≈ 10,234.31
