Find an equation of the line perpendicular to the graph.

Mathematics
1 answer:
topjm [15]3 years ago
8 0

Answer:

The equation of the line would be y = -1/4x + 2

Step-by-step explanation:

In order to solve this, start by finding the slope of the original line. You can do this by solving for y.

28x - 7y = 9

-7y = -28x + 9

y = 4x - 9/7

Now that we have a slope of 4, we know that the perpendicular slope is -1/4 (since perpendicular lines have opposite and reciprocal slopes). We can use this and the new point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 1 = -1/4(x - 4)

y - 1 = 1/4x + 1

y = -1/4x + 2

In parallelogram EFGH, the measure of angle G is (4x + 16)° and the measure of angle H is (2x − 16)°. What is the measure of ang
asambeis [7]

Answer:

m∠H = 44°

Step-by-step explanation:

Consecutive angles of a parallelogram are supplementary.  So,

∠H and ∠G are supplementary

4x + 16 + 2x - 16 = 180

6x = 180

x = 30

m∠H = 2x - 16 = 2(30) - 16 = 60 - 16 = 44°

Who can help with geometry
Kay [80]

Answer:

h = 21.5cm.

Step-by-step explanation:

<em>Step one:</em> Simplify the volume.

220.16 x (pi) = 691.65cm^3.

<em>Step two:</em> Isolate h.

Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.

Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.

<em>Step three:</em> Solve for h.

691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.

To illustrate this, please check the diagram below.
