$\bf tan(\theta)=12\implies tan^{-1}[tan(\theta)]=tan^{-1}(12)\implies \measuredangle \theta=tan^{-1}(12)$

now, assuming the angle is expected in degrees, thus, make sure your calculator is in Degree mode, when getting the inverse tangent

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. The

frosja888 [35]

Answer:

Step-by-step explanation:

Joint variation has the equation

y = kxz

k is the constant of variation and needs to be solved for using the initial conditions, then filled in later to another equation related to the given info to solve for something else. We are given y = amount of oil used, x = distance traveled, z-squared is the speed. Our equation looks like this, to be exact:

$y=kxz^2$

Filling in with the initial conditions:

$34=k(60)(20)^2$ which gives us the

k = .0014166667

Now we need to find the amount of oil used, y, under other circumstances, but this time we have our k.

$y=(.0014166667)(32)(23)^2$

which gives us that the amount of oil used, when rounded to the tenths,

y = 24.0 barrels

The Choi family wants to save money to travel the world. They purchase an annuity with a monthly payment of $65 that earns 4.5%

Lesechka [4]

Answer:

You can get an idea of how much guaranteed lifetime income a given amount of savings will buy by going to this annuity payment calculator. Today, for example, $100,000 would get a 65-year-old man about $525 a month in lifetime income, while that amount would generate roughly $490 a month for a 65-year-old woman.
