Which expression is equivalent to ^4√16x^11y^8/81x^7y^6 ? Assume x > 0 and y = 0

ollegr [7]

For this case we have an expression of the form:
 $\sqrt[4]{16x^{11}y^8}/(81x^7y^6)$
To solve the problem, we must rewrite the expression using properties of exponents.
Rewriting the expression we have:
$\sqrt[4]{2^4x^8x^3y^8}/(81x^7y^6)$
Then, by root properties we have:
$2x^2y^2(\sqrt[4]{x^3})/(81x^7y^6)
$
Then, by power properties again:
$2(\sqrt[4]{x^3})/(81x^5y^4)$
Answer:
An expression that is equivalent is:
 $2(\sqrt[4]{x^3})/(81x^5y^4)$

M<1 and m<2 are vertical angles if m<1 = 106° and M<2 equals 20x - 14 find M<2

just olya [345]

Answer:

Answer:

m∠2= 86

Step-by-step explanation:

since they are vertical angles, that means they are both equal to eachother.

so lets set them equal!

17x+1=20x-14

17x+15=20x

15=3x

x=5

now input x into m∠2

m∠2 = 20(5) – 14 = 86

Write the equation of the line perpendicular to y=5/3x+2 that passes through the point (-3,5)

Makovka662 [10]

Answer

The equation of the line in point-slope form is

y - 5 = (-3/5) (x + 3)

We can simplify this to obtain the slope-intercept form

y - 5 = (-3/5) (x + 3)

y - 5 = (-3x/5) - (9/5)

y = (-3x/5) - (9/5) + 5

y = (-3x/5) + (16/5)

Then, to put the whole thing in a simplified equation form, we multiply through by 5

y = (-3x/5) + (16/5)

5y = -3x + 16

3x + 5y = 16

Explanation

The general form of the equation in point-slope form is

y - y₁ = m (x - x₁)

where

y = y-coordinate of a point on the line.

y₁ = This refers to the y-coordinate of a given point on the line

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

x₁ = x-coordinate of the given point on the line

So, we just need to compute the slope of this line since a point on the line has already been provided (-3, 5)

For two lines with slopes m₁ and m₂ that are perpendicular to each other, the slopes are related through the relation

m₁m₂ = -1

And the slope-intercept form of the equation of a straight line is given as

y = mx + b

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

b = y-intercept of the line.

So, the slope of the line whose equation is given in the question is

m₁ = (5/3)

This is obtained by comparing y = mx + b with y = (5/3)x + 2

So, we can obtain the slope of the line that we need

m₁m₂ = -1

m₁ = (5/3)

m₂ = ?

m₁m₂ = -1

(5/3) × m₂ = -1

(5m₂/3) = -1

Cross multiply

m₂ = (-3/5)

So, we can write the equation in point-slope form now

Recall that

y - y₁ = m (x - x₁)

m = slope = (-3/5)

Point = (x₁, y₁) = (-3, 5)

x₁ = -3

y₁ = 5

y - y₁ = m (x - x₁)

y - 5 = (-3/5) (x - (-3))

y - 5 = (-3/5) (x + 3)

Hope this Helps!!!

When having the same radius and height what fraction of a cylinder have the same volume as one cone?

trasher [3.6K]

Answer:

1/3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone = 1/3(nr^2h)

n = 22/7

r = radius

h = height

If the volume of a cylinder is 300, the volume of a cone = 1/3 x 300 = 100

the capacity of a cone is 1/3 that of a cylinder
