Answer:

$7$

Solution:

This is a linear function. This means means that r is our rate of change.

To find r recal following formula

$r=\frac{\Delta y}{\Delta x} = \frac{y_2-y_1}{x_2-x_1}$

Since this is a linear function we can choose any two points. I will choose the first two for simplicity

$\Displaystyle \therefore r = \frac{42-14}{6-2}=\frac{28}{4}=7$

A 6 inch personal pizza has 650 calories, with 240 of those from fat. A 14 inch pizza is cut into 8 slices. Estimate the number

professor190 [17]

Answer:

Number of calories in one slice of a 14 inch pizza is 189.825. 

Step-by-step explanation:

Given that 6 inch pizza has 650 calories. 

Therefore 1 inch pizza has $\frac{650}{6}$ calories. 

14 inch pizza will have

$\frac{650}{6} \times 14=216.67 \times 14=1516.66 \ calories$

Given that the 14 inch pizza is divided into 8 slices.

Therefore each slice of the 14 inch pizza will have

 $\frac {1516.66}{8} =189.825 calories$

Answer:

(1/2)sin(2x) + C

Step-by-step explanation:

$y=2x\\\frac{dy}{dx} =2\\\ dx=\frac{dy}{2} \\\int\limits {cos 2x} \, dx \\\int\limits {cos(y) } \, \frac{dy}{2} =\frac{1}{2} \\\int\limits {cos(y) } \, dy=\frac{1}{2}sin(y) \\ substitute / y=2x\\\int\limits {cos 2x} \, dx = \frac{1}{2}sin(2x) +C$
