A population of mice is increasing exponentially. On Monday there were 120 most. One month later there were 132 most. Ready func

djyliett [7]

Answer:

$y=120 * 1.1^x$ --- function

The monthly rate is 10%

Step-by-step explanation:

Given

Let

$x \to months$

$y \to mice$

So, we have:

$(x_1,y_1) = (0,120)$ --- Monday

$(x_2,y_2) = (1,132)$ --- One month later

Required

The function

The function is represented as:

$y=ab^x$

In $(x_1,y_1) = (0,120)$ , we have:

$120 = a * b^0$

$120 = a * 1$

$120 = a$

$a=120$

In $(x_2,y_2) = (1,132)$ , we have:

$132 = a * b^1$

$132 = a * b$

Substitute: $a=120$

$132 = 120 * b$

Solve for b

$b = \frac{132}{120}$

$b = 1.1$

So, the function is:

$y=ab^x$

$y=120 * 1.1^x$

To calculate the monthly rate (r), we have:

$y =a(1 + r)^x$

Compare to: $y =ab^x$

$1 + r = b$

Make r the subject

$r = b-1$

Substitute $b = 1.1$

$r = 1.1-1$

$r = 0.1$

Express as percentage

$r = 0.1*100\%$

$r = 10\%$

Answer:

C. p(x) = 5x - 12.

Step-by-step explanation:

p(x) = 8x - (3x + 12) (Note you have to put the 3x+12 in parentheses).

p(x) = 8x - 3x - 12

p(x) = 5x - 12

Answer:

The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65

Step-by-step explanation:

Let x be the number of t-shirts and y be the total pay

As we can clearly see in the table that there is a linear relationship between x and y

A linear function is given as:

$y = mx+b$

Here m is the gradient of the function then

$m = \frac{y_2-y_1}{x_2-x_1}$

Taking any two pairs of x and y

(1,68) and (2,71)

$m = \frac{71-68}{2-1}\\m = 3$

Putting in equation

$y = 3x+b$

Putting a pair (1,68) in the equation to find the value of b

$68 = 3(1) + b\\68 = 3+b\\b = 68-3\\b = 65$

Putting the value of b

$y = 3x+65$

Let p(x) be the linear function

Hence,

The linear function is: p(x) = 3x+65
