Answer:

The answer to your question is 8649 persons

Step-by-step explanation:

Data

Equation              y = 11.89x - 15345.2

Year = x = 2018

Process

1.- Just substitute x in the equation

                            y = 11.89 (2018) - 15345.2

2.- Multiply 11.89 by 2018

                            y = 23994.02 - 15345.2

3.- Subtract to find x

                           y = 8648.82

4.- Conclusion

There was 8649 persons in 2018.

Mr. Wilson opened a bakery and a juice bar in his neighborhood. The functions below represent the profit, in dollars, earned fro
zavuch27 [327]

Answer:

The answer is given below

Step-by-step explanation:

The question is not complete, because the function for the profit is not given but I can show you how to calculate this.

Since Mr. Wilson has a bakery and a juice bar, his total profit earned in t months would be the sum of profit from the bakery with the profit from the juice bar within t months.

Let us assume that the profit from the bakery in t months is given by:

B(t) = 2t³

while the profit from the juice bar in t months is given by:

J(t) = 2.3^t-2

Therefore the total profit is given by:

P(t) = B(t) - J(t) = 2t^3+2.3^t-2

horsena [70]

Answer:

$0.75

Step-by-step explanation:

To find the answer multiply the amount of money earned by the percentage $14.98 and 5%

turn the percentage into a decimal. divide the number of the percentage by 100 5/100=0.05

multiply this by the amount of money to get 0.05*14.98=0.749. then round answer to two decimal places to get $0.75

State whether the given measurements determine zero, one, or two triangles.
ohaa [14]

Answer:

One

Step-by-step explanation:

Find the value of B

Applying the law of sines

\frac{a}{sin(A)} = \frac{b}{sin(B)}

substitute the given values

\frac{23}{sin(61)} = \frac{24}{sin(B)}

sin (B) = \frac{24}{23}Sin(61)

step 2

Find the measure of angle C

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

61 + 65.87 + C = 180

C = 53.13

step 3

Find the value of c

Applying the law of sines

\frac{a}{sin(A)} = \frac{c}{sin(C)}

substitute the given values

\frac{23}{sin(61)} = \frac{c}{sin(53.13)}

c = \frac{23}{sin(61)}SIN (53.13)

C=21.04 units

so

there can only be one value for each measurement, therefore there can only be one triangle
