Organisms A and B start out with the same population size. Organism A’s population doubles every day. After five days, the popul

ation stops growing and a virus cuts it in half every day for three days. Organism bees population grows at the same rate but it’s not infected with the virus. After eight days how much larger is organism B’s population an organism A’s population?

Answer:

1. 252N = (2^{2} x 3^{2} x 7^{1})N

2. Factor = 2^{5}

Step-by-step explanation:

Let the starting population size for organisms A and B be represented by N.

For organism A;

Day 0: N

Day 1: 2N

Day 2: 2^{2}N

Day 3: 2^{3}N

Day 4: 2^{4}N

Day 5: 2^{5}N

Day 6: 2^{4}N

Day 7: 2^{3}N

Day 8: 2^{2}N

For organism B;

Day 0: N

Day 1: 2N

Day 2: 2^{2}N

Day 3: 2^{3}N

Day 4: 2^{4}N

Day 5: 2^{5}N

Day 6: 2^{6}N

Day 7: 2^{7}N

Day 8: 2^{8}N

1. After the eight days, organism B's population is larger than organism A's population by;

2^{8}N - 2^{2}N = 256N - 4N

               = 252N

               = (2^{2} x 3^{2} x 7^{1})N

2. Organism A's population grows by 2^{5}.

Which value of a in the exponential function below would cause the function to stretch?
mote1985 [20]

Answer:

a' > a

Step-by-step explanation:

f(x)=ae^{bx}

A larger value for a will stretch the exponential in the y direction. A larger value for b will stretch it in the x direction.

triangle on right is the same as the triangle on the left

use pythagorean theorem

hypotenuse will give to the sides of the rectangle

a^2 + b^2 = hypotenuse squared

10.4^2 = 108.16

15.3^2 = 234.09

342.25 = hypotenuse squared

take the square root in both sides

hypotenuse = the square root of 342.25 =

18.5

add up the areas of the 2 triangles and rectangle

triangle area is 1/2 times 10.4 times 15.3 =

79.56

2 triangles areas are 159.12

rectangle area is 18.5 × 7 = 129.5

159.12 + 129.5 = 288.62

answer 1 = 288.62

second question:

to get 1 side take the

square root of 702.25 which is

26.5

to get the perimeter

multiply 26.5 by 4 which is

106

answer 2 is choice B 106

10. A weight hangs on a spring. The vibration period of that weight is the time in which it makes a complete cycle in motion. Su
Alenkinab [10]

The vibration period of the spring will be 0.2 seconds

<em><u>Explanation </u></em>

The relationship between the vibration period "T" (in seconds) and the weight "w" (in kilograms) is given by...

T= 2\sqrt{\frac{w}{200}}

Given that, the weight(w) = 2.0 kilograms

So, <u>plugging w = 2.0</u> into the above equation, we will get...

T= 2\sqrt{\frac{2.0}{200} } \\ \\ T= 2\sqrt{\frac{1}{100} }\\ \\ T= 2*\frac{1}{10}\\ \\ T= \frac{1}{5}=0.2

So, the vibration period of the spring will be 0.2 seconds.

Helllpppppppppp please someone.?????
Liula [17]

Answer:

(-5,5)

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(x+5y=20)

1(2x−7y=−45)

Becomes:

−2x−10y=−40

2x−7y=−45

Add these equations to eliminate x:

−17y=−85

Then solve−17y=−85for y:

(Divide both sides by -17)

y=5

x+5y=20

Substitute  5 for y in x+5y=20:

x+(5)(5)=20

x+25=20(Simplify both sides of the equation)

x+25+−25=20+−25(Add -25 to both sides)

x=-5
