(Show full work please) Carter spots an airplane on radar that is currently approaching in a straight line, and
Otrada [13]

Consult the attached diagram.

In the larger triangle,

tan(16°) = (7250 ft) / (<em>x</em> + <em>y</em>)

and in the smaller triangle,

tan(26°) = (7250 ft) / <em>y</em>

You want to solve for <em>x</em>.

From the first equation (I'm ignoring units from here on, all distances are measured in ft), you have

(<em>x</em> + <em>y</em>) tan(16°) = 7250

<em>x</em> tan(16°) + <em>y</em> tan(16°) = 7250

<em>x</em> tan(16°) = 7250 - <em>y</em> tan(16°)

<em>x</em> = 7250 cot(16°) - <em>y</em>

<em />

From the second equation,

<em>y</em> = 7250 cot(26°)

Solving for <em>x</em> gives

<em>x</em> = 7250 cot(16°) - 7250 cot(26°)

<em>x</em> = 7250 (cot(16°) - cot(26°))

<em>x</em> ≈ 10,433 ft

Find the 10th term of an arithmetic sequence if the common difference is 32 and the first term is 2
zaharov [31]

Answer:

290

Step-by-step explanation:

If the first term is 2 and the common difference is 32, then the formula for a(n) is:

a(n) = 2 + 32(n-1).

Thus, the 10th term is a(10) = 2 + 32(10-1)  =  2 + 32(9) = 290

PLEASE HELPPPP I DONT KNOW HOW TO DO THIS
KonstantinChe [14]

Answer:

I'm not an expert here, this is a best guess!

But I would say if there is no chance that of him incurring excess costs of less than $500, then he knows without insurance he'll end up paying at least $500, possibly more out of pocket, without the insurance.

so I would say He ends up spending the least amount out if pocket by going with option A. for $75. that's $75 out of pocket with no deductible and it covers his $500+ in excess costs....B and C would also cover the excess, but would each cost $140 or $275 out of pocket at the end of the day....

with that being said, I'd say it's worth it to buy the insurance....even if he doesn't have any excess costs, he's spent $75 dollars for the peace of mind to know he's covered either way, and if he does incur the excess costs he's spent $75 rather that $500+....Even if the excess charges are only $100, which it says there is no chance of happening, but still, then he's still saved $25 altogether. Unless I'm reading it wrong, Option A saves him the most money either way, and is worth it to buy the insurance!
