1. Which number makes this equation true? v 2 + 10v + 16 = (v + 8)(v + ?) (1 point) 2 4 6 8 2. What is the factored form of x 2
rusak2 [61]
1. The answer is two because if you factor what you can from the equation and then simplify, you are left with 2v+16=(v+8)(?), and by looking at it, the correct answer is two, or A. Review your work, make sure to check your answers before submitting
2. Since two simple factors of 8 are 4 and 2, and they add up to 6, the correct answer is (x+4)(x+2), or B
3. Again, two simple factors of 12 are -4 and -3, so the correct answer is (x-3)(x-4), or D
4. Basically, just factor the quadratic trinomial g^2-2g-24, which turns out to (G+4)(g-6), which is B

Suppose a city with population 800,000 has been growing at a rate of 5% per year. If this rate continues, find the population of
AleksandrR [38]

Answer:

2,340,208.5 or 2,340,209

Step-by-step explanation:

You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times.  But that would take a while.

we got 1.05 because the formula says that y = a( 1 + r ) power t

for a we will give it 1

so y = 1 ( 1 + 0.05) power t

it will give us 1.05

to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.

So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209

Sergio039 [100]
Well so far, Kate has saw 65% of her workout

65% of total = 26
0.65 * t = 26
t = 26/0.65
t = 40 laps

gayaneshka [121]

Answer:

\frac{1}{5x-5}

Step-by-step explanation:

=> \frac{x-1}{5(x-1)^2}

=> \frac{x-1}{5(x-1)(x-1)}

<u><em>Cancelling (x-1)</em></u>

=> \frac{1}{5(x-1)}

=> \frac{1}{5x-5}
