First, you have to apply the Pythagorean Theorem to this problem to solve for the hypotenuse.

22^2 + 15^2 = c^2

"C", which is the hypotenuse, is approximately 26.63 inches long. So, now add all the sides, and you should have 63.63 inches as your final answer.

4tantheta/12-tan^2=1
egoroff_w [7]
4tan \theta = 12 - tan^{2} \theta
tan^{2} \theta + 4tan \theta - 12 = 0

Let x = tan \theta
x^{2} + 4x - 12 = 0
(x + 6)(x - 2) = 0
x = -6, x = 2

tan \theta = -6, tan \theta = 2

Since they both work, then we can write the solutions in general form:
\theta = n \pi + tan^{-1}(2), n \in Z
\theta = n \pi - tan^{-1}(6), n \in Z

Now, these solutions will always satisfy the equation and substituting a whole number in place of n will produce a solution that satisfies the given equation.

Someone plz help me this is so hard
Radda [10]

Okay, so the first graph shows the amount that Leona is payed versus the number of newspapers she delivers.

We can clearly see from the graph; the more newspapers she delivers, the more she's payed.

For the second question (the table), it looks like the fixed fee for the boat rental was $27, as that's the number that really doesn't match the rest of the table. (Not to mention it's the very first number.

Then, the hourly rate is $12, as the price rises by 12 every hour after hour 1.

For the third question, the y-intercept is the amount of money in Colby's savings after x amount of years.
