Step-by-step explanation:

Set up a proportion

15 Liters / 4 gallons = 210 Liters / x      Cross Multiply

15x = 4 * 210                                           Combine the right

15x = 840                                                Divide by 15

Answer:

The function notation is when we represent one of the coordinate points as a function of the other ones.

In the general case, we will have:

y = f(x)

Now, we have that:

y = 7*x - 2

Then the function notation will be:

y = f(x) = 7*x - 2

or simply

f(x) = 7*x - 2

Answer:

f(x)= 7x-2

Answer:72,887

Step-by-step explanation: 500,000 - 427,113 = 72,887

Answer:

34,623 books

Step-by-step explanation:

First, add the amount taken out in November to the amount from the first 10 months of the year.

427,113 + 38,264

= 465,377

Then, subtract this from 500,000:

500,000 - 465,377

= 34,623

So, to meet the librarian's goal, 34,623 books need to go out in December.

Answer:  7.5²π   square centimeters.  OR  56.25π cm²

Step-by-step explanation:

Circumference = diameter × π

So the diameter is 15 cm

Area = πr²

Radius is half the diameter, so 15/2 or 7.5

Area = (15/2)²π cm²  

Answer:

The expression in the form [tex]7^n[/tex]

 [tex]7^2\times \:\:7^6=7^n[/tex]      

Step-by-step explanation:

[tex]7^2\:\times \:7^6[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}[/tex]

[tex]7^2\times \:7^6=7^{2+6}[/tex]

So the expression becomes

[tex]7^2\:\times \:7^6=7^{2+6}[/tex]

              [tex]=7^{2+6}[/tex]

Add the numbers: 2+6=8

              [tex]=7^8[/tex]

Therefore, the expression in the form [tex]7^n[/tex]

 [tex]7^2\times \:\:7^6=7^8[/tex]

Answer:

The population decreases by 140 in the next year.

Step-by-step explanation:

The increase that has no overall change in population cannot change the original amount of people there in the first place. If the population decreases by 140 in the next year, then there is no net gain or loss.

Answer:

800

Step-by-step explanation:

We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%

[tex]\frac{240}{x} = \frac{30}{100}[/tex]

Cross multiply and solve:

240 * 100 = 30x

24000 = 30x

800 = x

To calculate the exponential smoothing forecast for May, we need to use the formula Therefore the correct option is A  51.60 .

[tex]Ft = alpha * Xt + (1 - alpha) * Ft-1[/tex]  Where: - Ft is the forecast for time period t - Xt is the actual sales for time period t - Ft-1 is the forecast for the previous time period (t-1) - alpha is the smoothing constant Given that the forecast for January is 50, we can calculate the forecast for February as follows: [tex]F1 = 0.30 * 50 + (1 - 0.30) * 50 = 50[/tex] Similarly, we can calculate

the forecasts for March and April: F2 [tex]= 0.30 * 80 + (1 - 0.30) * 50 = 65[/tex] F3 [tex]= 0.30 * 70 + (1 - 0.30) * 65 = 66.50[/tex] F4 [tex]= 0.30 * 60 + (1 - 0.30) * 66.50 = 63.05[/tex] Now, to calculate the forecast for May: F5 [tex]= 0.30 * Xt-1 + (1 - 0.30) * Ft-1 F5 = 0.30 * 60 + (1 - 0.30) * 63.05 F5 ≈ 51.60[/tex]  Therefore, the forecast for May using exponential smoothing with a smoothing constant of 0.30 is approximately 51.60 (option a).

Hence the correct option is A

Answer:

X=7

Step-by-step explanation:

we already know the slope is -2, so y=-2x+m

since the line goes through point (5,1)

1=(-2)x5+m

1=m-10

m=11

the equation should be y=-2x+11

-3=2x+11

-14=2x
