1+tan^2(x) = sec^2(x)

sec^2(x) = 1/cos^2(x)

csc(-x) / 1/cos^2(x) =

cos^2(x) csc(-x)

jill bought a cd for $1000 that earns 4.2% apr and is compounded monthly. The cd matures in 2 years. How much will this cd be wo

OLEGan [10]

A = P(1+r/12)^12t, where A = amount after two years, P = Initial amount = $1000, r =apr = 4.2% = 0.042, t = period = 2 years

Then,

A = 1000 (1+0.042/12)^12*2 = $1087.47

Which number line best represents the solution to the inequality -18x+3<48

Doss [256]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given inequality

$-18x+3$

STEP 2: Solve for x

$\begin{gathered} -18x+3\frac{-45}{18} \\ x>-\frac{5}{2} \\ x>-2.5 \end{gathered}$

STEP 3: Plot the number line for that represents the final solution

Hence, the number line that best represents the final solution can be seen in the number line below:
