About Carrier culture initially contains 2500 bacteria and doubles every half hour​

Answers

Answer:

A bacteria culture initially contains 2500 bacteria and doubles every half hour. The formula for the population is p(t)=2500e^(kt) for some constant k. Find the size of the bacterial population after 100 minutes. Find the size of the bacterial population after 4 hours.

Step-by-step explanation:

Answer:

1. 10000 bacteria

2. 640000 bacteria

Step-by-step explanation:

2500 bacteria: 30 minutes

x bacteria: 60 minutes

The bacteria gets doubled twice

2500*2*2=10000

x bacteria:240 minutes

The bacteria gets doubles 8 times

2500*2*2*2*2*2*2*2*2= 640000

Find the measure of
A) 61
B) 55
B) 73
D) 60°

Answers

Answer:

60°

Step-by-step explanation:

180 - 115 = 65

180 = 65 + (9x + 6) + (9x + 1)

Subtract/simplify:

115 = 18x + 7

Subtract:

108 = 18x

Divide:

108/18 = 6

x = 6

Plug x back in:

9(6) + 6 = 54 + 6 = 60°

Which statement is true?

Answers

Answer:

Step-by-step explanation:

x-intercept -> when y = 0

f(x) x-intercept -> (1 , 0)

g(x) x-intercept -> (-1 , 0)

y-intercept -> when x = 0

f(x) y-intercept -> (0 , -1)

g(x) y-intercept -> (0 , 1)

The x-intercept of f(x) is greater than the x-intercept of g(x)

The y-intercept of g(x) is greater than the y-intercept of f(x)

So from the options, the answer is D. The x-intercept of f(x) is greater than the x-intercept of g(x)

Which equation of an exponential function has a graph that passes through the points
(1,5) and (2,15)?

Answers

Answer:

[tex]y = \frac{5}{3} (3^{x} )[/tex]

Step-by-step explanation:

In general, [tex]y = k(b^{x})[/tex]

Substitute x = 2, y = 15

(1)      [tex]15 = kb^{2}[/tex]

Substitute x = 1, y = 5

(2)      [tex]5 = kb^{1} = kb[/tex]

Divide equation (1) by equation (2)

[tex]\frac{15 = kb^{2} }{5= kb }[/tex]

3 = b

Now substitute b = 3 in equation (2) to find k

5 = k(3)

[tex]k = \frac{5}{3}[/tex]

Since we know the values for k and b, we now have the exponential function that passes thru (1, 5) and (2, 15)

[tex]y = \frac{5}{3} (3^{x} )[/tex]

Compare Texas to Carolina. Write the answer in scientific notation. Texas= 2.5x10 to the power of 5. Carolina= 1.2x10 to the power of 3.

Answers

Answer:

Texas is 2.08333 * 10^2 times the size of Carolina.

Step-by-step explanation:

Given :

Given that:

Texas= 2.5x10^5

Carolina = 1.2x10^3

Comparing the size of Texas and Carolina

Texas / Carolina

(2.5 * 10^5) ÷ 1.2 * 10^3

(2.5/1.2) * 10^5-3

2.08333 * 10^2

Hence, Texas is 2.08333 * 10^2 times the size of Carolina.

The length of a rectangle is 7 more than twice the width, and the area of the rectangle is 99 yd^2 . Find the dimensions of the rectangle

Answers

Answer:

Width of a rectangle = [tex]\frac{11}{2}[/tex] yards

Length of a rectangle = [tex]18[/tex] yards

Step-by-step explanation:

Let width be [tex]x[/tex] yards.

Length of a rectangle = [tex]7+2x[/tex]

Area of a rectangle = length × width

Put area of the rectangle as [tex]99\,\,yd^2[/tex]

Therefore,

[tex]99=x(7+2x)\\\\99=7x+2x^2\\\\2x^2+7x-99=0\\\\2x^2+18x-11x-99=0\\2x(x+9)-11(x+9)=0\\\\(2x-11)(x+9)=0\\\\x=\frac{11}{2},x=-9[/tex]

Being a dimension, [tex]x[/tex] cannot be negative.

So,

[tex]x=\frac{11}{2}[/tex]

Width = [tex]x=\frac{11}{2}[/tex] yards

Length of a rectangle = [tex]7+2x=7+2(\frac{11}{2})=7+11=18[/tex] yards
