Write an equation in point slope and slope intercept form of a line that passes through the given point and has the given slope

Evgesh-ka [11]

Answer:

Point-Slope: $y+4=-\frac{1}{2}(x+3)$

Slope-Intercept: $y=-\frac{1}{2}x-\frac{11}{2}$

Step-by-step explanation:

The point-slope formula is $y-y_{1}=m(x-x_{1} )$ . The slope-intercept formula is $y=mx+b$ . Since we are given the point and slope, we can directly plug it into the point-slope formula.

Point-Slope

$y-(-4)=-\frac{1}{2}(x- (-3))$

$y+4=-\frac{1}{2} (x+3)$

To find the slope-intercept form, we can manipulate the point-slope form to get the slope-intercept form.

Slope-Intercept

$y+4=-\frac{1}{2}x-\frac{3}{2}$

$y=-\frac{1}{2}x-\frac{11}{2}$

What is the volume of a cylinder with a diameter of 12 in. and a height of 7 in.?

Stels [109]

Answer

Find out the volume of a cylinder .

To prove

Formula

$Volume\ of\ cylinder = \pi r^{2}h$

Where r is the radius and h is the height.

As given

Diameter of 12 in. and a height of 7 in.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{12}{2}$

Radius = 6 in

$\pi = 3.14$

put all the values in the formula

$Volume\ of\ cylinder = 3.14\times 6\times 6\times 7$

= 791.28 in³

Therefore the volume of the cylinder is 791 .28 in³ .

You have $7000 with which to build a rectangular enclosure with fencing. The fencing material costs $30 per meter. You also want

Arlecino [84]

Answer:

1857.12 square meters

Step-by-step explanation:

Let L be the length of the rectangle and 'W' be the width

Perimeter = $2L + 2W + 2W$

The fencing material costs $30 per meter.

The material for the partitions costs $25 per meter

$cost=30(2L + 2W) +25( 2W)\\60L+60W+50W\\60L +110W$

$7000=60L+110W$

Solve for L

$7000=60L+110W\\7000-110W= 60L\\L=\frac{700}{6} -\frac{11}{6} W$

Area = length times width

$( \frac{700}{6} -\frac{11}{6} W)(W)\\A(W)=\frac{700}{6}W -\frac{11}{6} W^2$

Now take derivative and set it =0

$A(W)=\frac{700}{6}W -\frac{11}{6} W^2\\A'(W)=\frac{700}{6} -\frac{22}{6} W$

set the derivative =0 and solve for W

$0=\frac{700}{6} -\frac{22}{6} W\\\frac{700}{6}=\frac{22}{6} W\\W= 31.8$

So width = 31.8 that gives maximum area

$L=\frac{700}{6} -\frac{11}{6} (31.8)=58.4$

$Area = length \cdot width = 31.8 \cdot 58.4= 1857.12$ square meter
