Answer:

D -- the last one

Step-by-step explanation:

The formula tells you what to do.

t = 3

A0 = 25

A(t) = ?

A(3)  = 25 * (1/2)^3

A(t) = 25 * 1/8

A(t) = 25/8

A(t) = 3.125

Answer:

all except for D. he can build A, B, C and E out of the available pieces of fence.

but A violates the overall goal of a circumference of 30ft.

and E violates the overall goal of the garden having 4 sides.

D cannot be built, because it would require 3 pieces of 9 ft (and we have only 2).

Answer: All except for D.

Step-by-step explanation: I would make one, but someone has already made a decent explanation.

Answer:

The number of bacteria after t hours is given by: [tex]y(t) = 100e^{0.3219t}[/tex]

Step-by-step explanation:

Amount of bacteria after t hours:

Is given by the following equation:

[tex]y(t) = ae^{kt}[/tex]

In which a is the initial value and k is the constant of growth.

There are 100 bacteria initially

This means that [tex]a = 100[/tex]. So

[tex]y(t) = ae^{kt}[/tex]

[tex]y(t) = 100e^{kt}[/tex]

500 bacteria five hours later.

This means that [tex]y(5) = 500[/tex]. We use this to find k. So

[tex]y(t) = 100e^{kt}[/tex]

[tex]500 = 100e^{5k}[/tex]

[tex]e^{5k} = 5[/tex]

[tex]\ln{e^{5k}} = \ln{5}[/tex]

[tex]5k = \ln{5}[/tex]

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

[tex]k = 0.3219[/tex]

So

[tex]y(t) = 100e^{kt}[/tex]

[tex]y(t) = 100e^{0.3219t}[/tex]

The number of bacteria after t hours is given by: [tex]y(t) = 100e^{0.3219t}[/tex]

Answer:

1. There is a weak positive correlation.

Step-by-step explanation:

The correlation coefficient shows the relation of points in a data set. It is between 0 and 1 or 0 and -1. If the coefficient is closer to 0 then the correlation is weak. So, since 0.35 is closer to 0 than 1 it must be a weak correlation. Additionally, because it is positive the correlation must also be positive. A positive correlation means that the line of best fit will have a positive slope.

Answer:

Logan bought the stocks at $2,750,000

Step-by-step explanation:

So according to the question $3,437,500 is the amount at which 25% interest was made

This means that the original value(100% value) has been increased to 125%(thus 100+25%)

By using ratio and proportion,

If 125%-$3437500

then 100% ={100%/125%}×$3,437,50

=$2,750,000

Answer:

The prediction for the population in 2012 will be of 324.9 million.

Step-by-step explanation:

Exponential equation for population growth:

Considering that the population growth varies directly with time, it's value after t years is given by:

[tex]P(t) = P(0)e^{kt}[/tex]

In which P(0) is the initial value and k is the growth rate.

The population of the United States in 1990 was approximately 249 million

This means that [tex]P(0) = 249[/tex], so:

[tex]P(t) = P(0)e^{kt}[/tex]

[tex]P(t) = 249e^{kt}[/tex]

In 2000, 281 million.

2000 - 1990 = 10, so [tex]P(10) = 281[/tex]. We use this to find k.

[tex]P(t) = 249e^{kt}[/tex]

[tex]281 = 249e^{10k}[/tex]

[tex]e^{10k} = \frac{281}{249}[/tex]

[tex]\ln{e^{10k}} = \ln{\frac{281}{249}}[/tex]

[tex]10k = \ln{\frac{281}{249}}[/tex]

[tex]k = \frac{\ln{\frac{281}{249}}}{10}[/tex]

[tex]k = 0.0121[/tex]

So

[tex]P(t) = 249e^{0.0121t}[/tex]

Use this information to predict the population for 2012.

2012 - 1990 = 22, so this is P(22).

[tex]P(22) = 249e^{0.0121*22} = 324.9[/tex]

The prediction for the population in 2012 will be of 324.9 million.

Answer:

X=0

Y= -2

Step-by-step explanation:

Y+2=x

Y+10=2x+8

Y+2=x

Y+10=2(y+2)+8

Y+10=2y+12

Y-2y=-10+12

Y=-2

As it is right angled, thus it will be equal to 90.

= 2x + 5 + x + 25 = 90

= 3x + 30 = 90

= 3x = 60

= x = 60/3

= x = 20

Answer:

x = 20°

Step-by-step explanation:

[tex]2x + 5 + x + 25 = 90 \\ 3x + 30 = 90 \\ 3x = 90 - 30 \\ 3x = 60 \\ x = \frac{60}{3} \\ x = 20 \\ [/tex]

Step-by-step explanation:

2a+30 = 4a-4

+4 +4

2a+34 = 4a

-2a -2a

34 = 2a

÷2 ÷2

a=17

Hope this helps! :)

Answer:

A = 17

Step-by-step explanation:

Opposite angles are congruent in a parallelogram

Hence 2a + 30 = 4a - 4

( Note that we've just created an equation that we can use to solve for a)

We now solve for a

2a + 30 = 4a - 4

Add 4 to both sides

2a + 34 = 4a

Subtract 2a from both sides

34 = 2a

Divide both sides by 2

a = 17

156 were there on the fourth day.

Step-by-step explanation:

125% of the number she received on the previous day

This means that the previous day number is multiplied the 125%/100% = 1.25.

64 responses the first day

This means that the number of responses after x days is given by:

[tex]R(x) = 64(1.25)^x[/tex]

Number of male students = 2

To find:

Total number of outcomes if 3 students are chosen at random (Should i find the probability of something?)

Steps:

To find the total number of outcomes, we need to list the outcomes

Outcomes = {M,M,F} , {M,F,F} , {F,F,F}

Therefore, the total number of outcomes if 3 students are chosen at random is 3, if we don't consider order.

Answer:

Slope = - 2.5

Step-by-step explanation:

A right angled triangle is drawn to meet the best fit line at any point on the graph,, the point at which the triangle meets the best fit line, provides the values for the rise and run used to calculate the slope, the ris ubsyge cgbage in y values and run is the change in x values ;

Rise, y2 = - 1 ; y2 = 4

Run ; x2 = 3 ; x1 = 1

Rise = y2 - y1 = - 1 - 4 = - 5

Run = x2 - x1 = 3 - 1 = 2

Slope = Rise / Run = - 5 / 2 = - 2.5
