Tamara has decided to start saving for spending money for her first year of college. Her money is currently in a large suitcase

katovenus [111]

Answer:

She can create a function for the total savings in terms of the time x by adding the two functions together. The new function should look like this:

T(x)=S(x)+a(x)

So now we can substitute the given functions:

T(x)=450+6(x-2)

But this function can be simplified for it to be easier for her to calculate her total amount of savings. We can do that by distributing the 6 into the parenthesis. This is, multiply the 6 by both the x and the -2, so we get:

T(x)=450+6x-12

and now we can combine like terms. We can subtract 12 from 450 so we get:

T(x)=6x+438

And that will be our final function.

The angle of elevation to the bottom of the rainbow is 42°

Explanation:

Given that the bottom of a double rainbow is going over a tree that is 18 feet tall and you're standing 20 feet from the tree.

We need to determine the angle of elevation to the bottom of the rainbow.

Let us use the trigonometric ratios to determine the angle of elevation.

Thus, we have,

$tan \ \theta=\frac{opp}{adj}$

where opp = 18 and adj = 20 and we need to determine the angle.

Substituting the values, we have,

$tan \ \theta=\frac{18}{20}$

Dividing the values, we have,

$tan \ \theta=0.9$

Taking $tan^{-1$ on both sides of the equation, we get,

$\theta=tan^{-1}(0.9)$

Thus, we get,

$\theta=41.99^{\circ}$

Rounding off to the nearest degree, we get,

$\theta=42^{\circ}$

Hence, the angle of elevation to the bottom of the rainbow is 42°
