X over 8 is greater than or equal to 1 . <br> Solve &amp; graph
Andrew [12]

                                           x/8 > or = 1

Multiply each side by 8 :      <em>  x > or = 8</em>

To graph this inequality:

-- Draw the line  x = 8

-- The inequality represents all the points on this line AND
all points in all of the area to the right of the line.

4+2p=10( 5/3p−2)<br> Solve
worty [1.4K]

Answer:

p=18/11

Step-by-step explanation:

Simplify: 4+2p=50/3p-20

Multiply each side by 3: 12+6p=50p-60

Add like terms: -44p=-72

Divide both sides by -44 and simplify:  p=18/11

radius = diameter/2

radius = 6.5/2  =   \frac{13}{4}m

<span>volume  </span>=  \frac{4}{3} x \pi x (radius)³

              =  \frac{4}{3} x \pi x ( \frac{13}{4})^3

              =  \frac{4}{3} x \pi x \frac{2197}{64}

              =  \frac{2197}{64}

              = 144 cubic meters

Use the following information for problems 1 – 3. Suppose you sign a contract for an annual salary of $50,000 with a guaranteed
erik [133]

Initial salary =  $50,000 .

Rate of raise = 5% each year.

Therefore, each next year salary would be 105% that is 1.05 times.

5% of 50,000 = 0.05 × 50000 = 2500.

Therefore raise is $2500 each year.

According to geometric sequence first term 50000 and common ratio 1.05.

Applying geometric sequence formula

a_n = ar^{n-1}

1) a_n = 50000(1.05)^{n-1}

2) In order to find salary in 5 years we need to plug n=5, we get

a_5 = 50000(1.05)^{5-1}= 50000(1.05)^4

= 50000(1.21550625)

<h3>=$60775.3125.</h3>

3) In order to find the total salary in 10 years we need to apply sum of 10 terms formula of a geometric sequence.

S_n = \frac{a(1-r^n}{1-r}

Plugging n=10, a = 50000 and r= 1.05.

S_10 = \frac{50000(1-(1.05)^{10}}{1-1.05}

S_10 = \frac{50000(0.050)^{10}}{0.05}

= 628894.62678.

<h3>Therefore , you will have earned $ 628894.62678 in total salary by the end of your 10th year.</h3>
