How much time would it take for a population to double at a rate of 8.2% per year continuously?

You want to find t such that
  2 = 1·e^(0.082t)
  ln(2) = 0.082t . . . . . take the natural log
  ln(2)/0.082 = t ≈ 8.453

It would take about 8.5 years for a population to double at 8.2% per year.

Answer:

Step-by-step explanation:

1.

(c+9)^2=64=8^2\\

c+9=±8

either c=8-9=-1

c=-8-9=-17

so c=-1,-17

D

2.

8x^2-3=2

8x^2=5

x^2=\frac{5}{8}=\frac{10}{16}

x=±\frac{\sqrt{10}}{4}

so A

3.

x^2+4x+4=18\\(x+2)^2=9*2\\x+2=3\sqrt{2} \\x=-2  ±3\sqrt{2}

so D

The coordinate grid shows points A through K. What point is a solution to the system of inequalities?
Eddi Din [679]

Answer:

Option D) F

Step-by-step explanation:

we have

y < -2x+10 -----> inequality A

The solution of the inequality A is the shaded area below the dashed line y=-2x+10

The y-intercept of the dashed line is (0,10)

The x-intercept of the dashed line is (5,0)

y < \frac{1}{2}x-2 ----> inequality B  

The solution of the inequality B is the shaded area below the dashed line y=\frac{1}{2}x-2

The y-intercept of the dashed line is (0,-2)

The x-intercept of the dashed line is (4,0)

The solution of the system of inequalities is the shaded area between the two dashed lines

see that attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution

therefore

The solution are the points

E, F and G

Marisa can buy 3 oranges for 1.35 dollars ,four oranges for $1.80 or five oranges for $2.25 per second by 10 oranges for a price
scZoUnD [109]
3 oranges= $1.35, so one orange cost $0.45
4 oranges= $1.80, one orange cost $0.45
5 oranges= $2.25, one orange cost $0.45
If one orange cost $0.45, then ten cost $4.50 ($0.45*10)

If you were to buy ten oranges are $4.25, this would make each orange $0.425 ($0.43 rounded).

This means that if you were to buy ten oranges, it would be cheaper to buy ten for $4.25, instead of buying two lots of 5 for $2.25 each.

Hope this helps :)
