First find the O. Using Pythagorean theorem, O = 2sqrt(13)

Now let's establish the rules:
(We will use x instead of theta since I don't have that symbol on my phone)

sinx = O/H = 2sqrt(13)/14 = sqrt(13)/7
cosx = A/H = 12/14 = 6/7
tanx = O/A = 2sqrt(13)/6 = sqrt(13)/3
cscx = H/O = 14/2sqrt(13) = 7/sqrt(13)
secx = H/A = 14/12 = 7/6
cotx = A/O = 6/2sqrt(13) = 3/sqrt(13)

When given <br> Slope= -6/5<br> Y-intercept= 2 <br> What is this in Point-Slope form?

Answer: $\textsf{y - 2 = -6/5(x - 0)}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Slope = -6/5, Goes through (0, 2)}$

Find: $\textsf{The equation in point-slope form}$

Solution: We need to take the values that were given to us and plug them into the point-slope form. It doesn't seem like the problem is asking for anything more than that so we will leave it at that.

<u>Plug in the values</u>

$\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - 2 = -6/5(x - 0)}$

Since the problem is just asking for the equation in point-slope form the final expression would be y - 2 = -6/5(x - 0).

Given the sequence tn defined recursively below, find t4.

Alina [70]

Answer:

$t_4 = 20$

Step-by-step explanation:

The base case in the recursive function are:

$t_1 = 1$

$t_2 = 2$

The recursive case is equal to:

$t_n = 2t_{n-1} + 3t_{n-2}$

So replace $t_n$ for $t_4$ :

$t_4 = 2t_{3} + 3t_{2}$

In the new expression $t_2$ is a base case so you don't have to worry for that part, but $t_3$ is still the recursive case so evaluate again in $t_n$

$t_3 = 2t_{2} + 3t_{1}$

$t_2$ and $t_1\\$ are define as base cases so you replace for it's numbers:

$t_3 = 2(2) + 3(1) = 7$

Now return to $t_4$ and replace for the new values:

$t_4 = 2(7) + 3(2) = 14 + 6 = 20$

So the final answer is 20

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each sale

LenaWriter [7]

Based on the amount that both Salesmen A and B earn per sale, the number of sales they both had was 12 sales.

<h3>How many sales did Salesmen A and B have?</h3>

Sales commission is a key aspect of sales compensation. It's the amount of money a salesperson earns based on the number of sales they have been able to make.

We are told that;

Salesman A gets $65 per sale.

Salesman B gets $300 and $40 per sale.

Assuming the number of sales to take them both to the same amount is x, the relevant formulas would be:

65x = 300 + 40x

Rearranging gives;

65x - 40x = 300

25x = 300

x = 300/25

x = 12 sales

The amount that salesman A earned is = 65 * 12 = $780

The amount that salesman B earned is = 300 + (40 * 12) = $780
