It is written as 16-3 because it is 16 subtract 3 not 3 subtract 16 because that would come out to a negative integer.

Write the equation of the line perpendicular to -6x+3y=6 that passes through (2,0). Write you answer in slope-intercept form

Svetach [21]

Answer:

The answer is: y - 0 = -1/2(x - 2)

Step-by-step explanation:

Given - an equation in standard form:

-6x + 3y = 6

Solve for y:

Add 6x to both sides:

3y = 6 + 6x

y = 2 + 2x

y = 2x + 2, so the slope is 2.

The perpendicular slope is the negative inverse of 2, which is -1/2.

Point slope form is:

y - y1 = m(x - x1)

Substitute in the numbers from the point (2,0) and the slope -1/2:

y - 0 = -1/2(x - 2)

Taking it to y intercept form:

y = -1/2x + 1

GUYS I NEED HELP ASAP!!! Help me solve ?

Shalnov [3]

Solution:

$$h=\frac{ A-2\pi r^2}{2\pi r }$

Given data:

$A=2\pi r^2+2\pi r h$

Let us determine what is h using given A.

$A=2\pi r^2+2\pi r h$

Subtract $2\pi r^2$ on both sides of the expression.

⇒ $A-2\pi r^2=2\pi r^2+2\pi r h-2\pi r^2$

⇒ $A-2\pi r^2=2\pi r^2-2\pi r^2+2\pi r h$

⇒ $A-2\pi r^2=2\pi r h$

Divide both sides of the expression by $2\pi r$ .

$$\frac{ A-2\pi r^2}{2\pi r }=\frac{2\pi rh }{2\pi r }$

$$\frac{ A-2\pi r^2}{2\pi r }=h$

$$h=\frac{ A-2\pi r^2}{2\pi r }$

Option C is the correct answer.

Hence $$h=\frac{ A-2\pi r^2}{2\pi r }$ .

PLEASE HELP ASAP!!

Answer: Option C.

Step-by-step explanation:

You must use the formula for calculate the volume of a cone, which is shown below:

$V_\frac{1}{3}r^2h\pi$

Where r is the radius and h is the height.

Based on the figure attached:

$r=3in\\h=7in$

Substitute these values into the formula for calculate the volume of a cone, then the result is:

$V_\frac{1}{3}(3in)^2(7in)\pi$

$V=65.97in^3$ ≈66in³

Which strategy would you use to find 2+8?Explain how you decided.

Ne4ueva [31]

You add 2 to 8 to get 10. I decided on that because that's just what you do for simple addition. ;)
