Find m2D. D C A 88° B​
Rasek [7]

Answer:

\huge\boxed{\sf \angle D = 92\°}

Step-by-step explanation:

<h3><u>Statement:</u></h3>
  • If a quadrilateral is inscribed in a circle, the opposite angles add up to 180 degrees.
<h3><u>According to the statement:</u></h3>

∠D + 88° = 180°

<em>Subtract </em>88 to both sides

∠D = 180° - 88°

∠D = 92°

The graphs below shows a change in the slope of the Line m from 34to 14.
Paladinen [302]

Look at the image attached to my answer.

When x is 12 for the first graph, we see that y is roughly 9. When x is 12 for the second graph, we see that y is roughly 3.

Thus, the value of y decreased from 9 to 3 after the change was applied to line M.

Let me know if you need any clarifications, thanks!

A prism whose base is a 9-sided polygon is intersected by a plane. In which case could the cross section be a 10-sided polygon?
Vikki [24]
The <u>correct answer</u> is:

D) <span>when the plane makes a narrow angle with the base.

Explanation:

If a cross section of a prism is taken <u>parallel</u> to the base, the cross section will be the <u>same shape</u> as the base.  In this case, it will be a 9 sided polygon.

If a cross section of a prism is taken <u>perpendicular</u> to the base, the cross section will be a <u>rectangle</u>, no matter how many edges the cross section goes through.

The only way to get a cross section with more sides than the original figure is to take a slant cross section, or one with an angle other than 90</span>° or 180° to the base.  This makes D our only option.

Solve x/4&gt;_-1 and -4x-4&lt;_-3 and write the solution in interval notation. If there is no solution, type the no solution sym
Rainbow [258]

The solution interval for x is x ∈ (-1/4 , ∞)

An inequality shows the relationship of a non-equal comparison between two numbers or mathematical expressions.

Here, we are given two inequalities

x/4 > -1 and -4x - 4 < -3

Let us take the first equation

x/4 > -1

⇒ x > 4(-1)

x > -4

Now, the second equation

-4x - 4 < -3

-4x < -3 + 4

-4x < 1

Now since we are dividing both sides by a negative number, that is 4, the sign of the inequality will be reversed,

x > 1/-4

x > -1/4

Thus, we get x > -4 and x > -1/4

This means that all values of x greater than -1/4 will satisfy.

Thus, x ∈ (-1/4 , ∞)
