Which graph represents a line with a slope of and a y-intercept equal to that of the line y = x – 2? HELP!!!!!!!!!!!!!!!!!!!!!!!

Arlecino [84]

None of the graphs have a slope and y-intercept equal to y = x - 2.

y = x - 2 has a slope of 1 and y-intercept of -2, none of the graphs you shown have a slope of 1.

A cylinder shaped can needs to be constructed to hold 400 cubic centimeters of soup. The material for the sides of the can costs

LenKa [72]

Answer:

The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.

Step-by-step explanation:

Volume of the Cylinder=400 cm³

Volume of a Cylinder=πr²h

Therefore: πr²h=400

$h=\frac{400}{\pi r^2}$

Total Surface Area of a Cylinder=2πr²+2πrh

Cost of the materials for the Top and Bottom=0.06 cents per square centimeter

Cost of the materials for the sides=0.03 cents per square centimeter

Cost of the Cylinder=0.06(2πr²)+0.03(2πrh)

C=0.12πr²+0.06πrh

Recall: $h=\frac{400}{\pi r^2}$

Therefore:

$C(r)=0.12\pi r^2+0.06 \pi r(\frac{400}{\pi r^2})$

$C(r)=0.12\pi r^2+\frac{24}{r}$

$C(r)=\frac{0.12\pi r^3+24}{r}$

The minimum cost occurs when the derivative of the Cost =0.

$C^{'}(r)=\frac{6\pi r^3-600}{25r^2}$

$6\pi r^3-600=0$

$6\pi r^3=600$

$\pi r^3=100$

$r^3=\frac{100}{\pi}$

$r^3=31.83$

r=3.17 cm

Recall that:

$h=\frac{400}{\pi r^2}$

$h=\frac{400}{\pi *3.17^2}$

h=12.67cm

The dimensions of the can that will minimize the cost are a Radius of 3.17cm and a Height of 12.67cm.

A line has the points (3,7) (4,9) (5,11) (6,13). If the slope is divided by 2, what is the new slope?

lorasvet [3.4K]

Answer:

The new slope is 1

Step-by-step explanation:

The slope of any two points can be found by:

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Finding slope of (3,7) (4,9)

$slope=\frac{9-7}{4-3}\\slope=\frac{2}{1}\\slope=2$

Finding slope of (4,9) (5,11)

$slope=\frac{11-9}{5-4}\\slope=\frac{2}{1}\\slope=2$

So, the slope of the line is 2

Now if slope is divided by 2, new slope will be:

$slope = \frac{2}{2}\\slope=1$

So, The new slope is 1
