Answer:

C) (0,5)

Step-by-step explanation:

f(x) is y and x is x

The table is providing you with points

y-y over x-x gives you a slope of -5

Use the points and turn it into a point-slope equation and convert to y-intercept equation

y-15=-5(x+2)

y-15=-5x-10

y=-5x+5

So the y-intercept is 5 or (0,5)

$\textrm {Cylinder volume :}$

$\mathrm {Volume = \pi r^{2}{h}}$

$\mathrm {Volume = 3.14 \times (\frac{4}{2})^{2} \times 3}$

$\mathrm {Volume = 3.14 \times 12}$

$\mathrm {Volume = 37.68cm^{3}}$

$\textrm {Rectangular prism volume :}$

$\mathrm {Volume = length \times width \times height}$

$\mathrm {Volume = 6 \times 5 \times 7}$

$\mathrm {Volume = 30 \times 7}$

$\mathrm {Volume = 210cm^{3}}$

$\textrm {Total volume of composite figure :}$

$\textrm {Volume of cylinder + volume of rectangular prism}$

$\mathrm {37.68 + 210}$

$\mathrm {247.68cm^{3}}$
