The answer to your question is: 
It is a quadratic equation in 'x', with 'n' mistakenly typed in the second term..

Although you didn't ask for the solutions to the equation, I'm already here
so I might as well go through it and find them:

<span><u>3x² - 2x - 5 = 0</u></span>

In terms of the generic quadratic formula:
A = 3
B = -2
C = -5

Plug those into the quadratic formula, and you discover that

<u>x = -1</u>
and
<u>x = ⁵/₃</u>

3x^2-2x-5=0

(3x-5)(x+1) = 0

3x-5=0

3x=5

x= \frac{5}{3}

x+1 =0

x=-1

x=-1, \frac{5}{3}

Find the interest generated if one invests $6000 for 9 years at 7% per annum with interest compounded monthly
marysya [2.9K]

Answer:

principle= 6000

time =9 years

rate = 7%

so,

compound interest = p((1+r/100)^t. -1)

= 6000((1+0.07)^9 -1)

=6000(1.84-1)

=6000*0.84

=5040

Black Diamond Ski Resort charges $50 for ski rental and $15 an hour to ski. Bunny Hill Ski Resort charges $75 for ski rental and
andrew11 [14]

Answer:

The cost of 5 hours of skiing would be the same ($125) after 5 hours.

Step-by-step explanation:

Black Diamond:  ChargeBD(h) = $50 + ($15/hr)h, where h is the number of hours spent skiing.

Bunny Hill:  ChargeBH(h) = $75 + ($10/hr)h

We equate these two formulas to determine when the cost of using the ski slopes is the same:

ChargeBD(h) = $50 + ($15/hr)h = ChargeBH(h) = $75 + ($10/hr)h

We must now solve for h, the number of hours spent skiing:

50 + 15h = 75 + 10h

Grouping like terms, we obtain:

5h = 25, and so h = 5 hours.

The cost of 5 hours of skiing would be the same ($125) after 5 hours.

Find the measure of arc FV
stepladder [879]

Answer:

FV = 60

Step-by-step explanation:

VG => 65 × 2 = 130

FH major arc=> 119 × 2 =  238

<u>FH major arc -  GH = FG</u>

FG => 238 - 168 = 70

<u>VG - FG major arc = FV</u>

FV => 130 - 70 = 60
