Answer:

a(n) = -9 + 7(n - 1) (Answer a)

Step-by-step explanation:

Each new term is found by adding 7 to the previous term. Thus, the formula will include "+ 7." The first term is -9.

The general formula for an arithmetic sequence is a(n) = a(1) = h(n - 1), where h is the "common difference" (which here is 7).

Thus, the desired formula is a(n) = -9 + 7(n - 1) (Answer a)

Rachel earned \$34$34 in 44 hours at her job today. She wants to know how much she could earn (e)(e) tomorrow if she works 1010

kari74 [83]

Answer:

<em>Rachel will earn $85 in 10 hours.</em>

Step-by-step explanation:

Rachel earned $34 in 4 hours at her job today.

Suppose, she will earn $x$ dollar in 10 hours tomorrow.

So, <u>according to ratio of 'dollar' and 'hours'</u>, the equation will be.....

$\frac{34}{4}=\frac{x}{10}$

After cross multiplying, we will get.....

$4x= 34*10\\ \\ 4x= 340\\ \\ x=\frac{340}{4}=85$

Thus, Rachel will earn $85 in 10 hours.

In ΔPQR, the measure of ∠R=90°, the measure of ∠P=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.

Vitek1552 [10]

Answer:

3.7feet

Step-by-step explanations

Using the sin rule

A/sin a = B/sin b

Let A = PQ = 8.5feet

B = QR = x feet

a = R = 90°

b = P = 26°

Substitute the values into the Sin rule

8.5/sin90 = x/sin26

8.5×sin 26 = x × sin 90

8.5×0.4383 = x× 1

3.7255 = x

Hence the length of QR to the nearest tenth 3.7feet

What is the simplified form of the following expression?

Amanda [17]

You have sqrt(8), sqrt(18), and sqrt(2).
You need to simplify the radicals.
sqrt(2) is already simplified.
For both sqrt(8) and sqrt(18), you need to factor out the greatest perfect square.

8 = 4 * 2
You can take the square root of 4 and put it outside the root.

18 = 9 * 2
You can take the square root of 9 and put it outside the root.

$5 \sqrt{8} - \sqrt{18} -2 \sqrt{2} =$

$= 5 \sqrt{4 \times 2} - \sqrt{9 \times 2} -2 \sqrt{2}$

$= 5 \times 2\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}$

$= 10\sqrt{2} - 3 \sqrt{2} -2 \sqrt{2}$

$= 5\sqrt{2}$
