Help me im having trouble on slopes

Answers

Answer 1

Answer:

The slope-intercept form of an equation looks like this: y=mx+b

The m stands for the slope and the b stands for the y-intercept.

We need two points from the line to write out this equation.

For example (-2,0) and (1,2)

Now that we have the slope, we can plug it into our equation: y= 2/3x + b

To get b, our y-intercept, we just need to plug in one of the points found and solve. For example (-2,0)

Now that we have both our m and b values, we can plug them in to get our equation: y=2/3x + 4/3

Step-by-step explanation:

$m= (y1-y2)/(x1-x2) = (0-2)/(-2-1)$

$m=(-2)/(-3) = (2)/(3)$

$0=(2)/(3)(-2)+b$

$0=-(4)/(3)+b\n 0+(4)/(3)=-(4)/(3)+(4)/(3)+b\n 0+(4)/(3)=b\n (0*3)/(3)+(4)/(3)=b\n (4)/(3)=b$

Find the volume of the cone.Either enter an exact answer in terms of or use 3.14 for radius is 6 height is 8

Answers

Answer:

Hey there!

Cone formula: $\pi$ hr^2/3

Plugging in the values, we get the volume is 301.59

Let me know if this helps :)

Answer:

96π

301.59

Step-by-step explanation:

The volume of a cone can be calculated using the following formula:

$V=(1)/(3)bh$

b is the base and h is the height. The base formula for a circle (area):

$b=\pi r^2$

Insert this value into the formula:

$V=(1)/(3)\pi r^2h$

Simplify the formula:

$V=(\pi r^2h )/(3)$

Now insert the known values:

$V=(\pi(6)^2(8) )/(3)$

Simplify:

$V=(\pi*36*8 )/(3)\n\nV=(288\pi )/(3)\n\nV=96\pi$

The volume is 96π units³ or 301.59 units³.

An equilateral triangle has a perimeter of 60m and a height of 17.3m. what is its area?

Answers

The area of any triangle is (1/2) x (length of the base) x (height) .

In this problem, we know the triangle's height,
but what is the length of the base ?

The base is the side that the triangle is sitting on. This particular triangle
is an equilateral one, and its perimeter is 60m. So each side must be 20m.
No matter which side the triangle is sitting on, the length of the base is 20m.

Area = (1/2) x (base) x (height)

Area = (1/2) x (20m) x (17.3m) = 173 m²

Divide 60/3 so you get 20. So take 20x17.3 and you should get 346m∧2
