Answer: The parallel slope of 2/3 is 2/3 . m=2/3

Step-by-step explanation: Parallel slopes have the same slopes.

If a slope is 2/3, the parallel slope will be the same. So, the parallel slope will also be 2/3.

Therefore, the answer is m=2/3

Answer:

No.

Step-by-step explanation:

Parallel lines have the same slope. Perpendicular lines have opposite reciprocal slopes. In this instance, -3/2 is perpendicular to 2/3, not parallel.

The radius of a sphere is increasing at a rate of 2 mm/s. How fast is the volume increasing when the diameter is 100 mm?

Advocard [28]

Answer:

Volume increasing rate = $62831.85 mm^3/s$

Explanation:

We rate of change of radius of sphere, $\frac{dr}{dt} =2mm/s$

Diameter of sphere = 100 mm

Radius of sphere = 50 mm

Volume of sphere, V = $\frac{4}{3} \pi r^3$

Rate of change of volume = $\frac{dV}{dt}$

$\frac{dV}{dt}=\frac{d}{dt} (\frac{4}{3} \pi r^3)=\frac{4}{3} \pi\frac{d}{dt}(r^3)=\frac{4}{3} \pi*3r^2*\frac{dr}{dt}$

Substituting known values

$\frac{dV}{dt}= \frac{4}{3}* \pi*3*50^2*2=62831.85 mm^3/s$

Volume increasing rate = $62831.85 mm^3/s$

0=-2y+10-6x<br> 14-22y=18x

Inessa05 [86]

Answer:

x=2,y=−1

Step-by-step explanation:

Solve for y in the first equation.

y=−9x/11+7/11

0=−2y+10−6x

Replace all occurrences of y with −9x/11+7/11 in each equation.

0=−48(x−2)11

y=−9x11+711

Solve for x in the first equation.

x=2

y=−9x/11+7/11

Replace all occurrences of x with 2 in each equation.

y=−1

x=2

The solution to the system is the complete set of ordered pairs that are valid solutions.

(2,−1)

The result can be shown in multiple forms.

Point Form:

(2,−1)

Equation Form:

x=2,y=−1

Triangle abc is located on a coordinate plane angle c is at (1,2) the triangle is rotated counter clockwise 90° about the origin

sertanlavr [38]

After rotating a point C 90° counterclockwise about the origin the coordinates of C' would be (-2, 1)

In this question, we have been given a triangle ABC.

A point C is at (1, 2)

The triangle is rotated counter clockwise 90° about the origin.

We need to find the coordinates of C' which is image of vertex C after rotation.

We know that, if we rotate a point 90° counterclockwise about the origin a point (x, y) becomes (-y, x).

Here C(1, 2) is rotated 90 degrees counterclockwise about the origin.

So, the coordinates of C' would be,

C' = (-2, 1)

Therefore, after rotating a point C 90° counterclockwise about the origin the coordinates of C' are (-2, 1)
