<h2>Answer:</h2>

To determine the answer, we must graph each point and the line.

According to this graph, the point that lies on the line is <em>B. (0, 2)</em>.

*Note: the line shown on the graph is $y = \frac{3}{11}x + 2$ , which is the <em>equivalent</em> of the one in the question. All I did was solve the equation for <em>y</em> to convert it to <em>slope-intercept form</em>.

Write an exponential function in the form y = ab" that goes through points (0,19)<br> and (6, 1216).

Elanso [62]

The exponential function is $y=19*2^x$

Step-by-step explanation:

The exponential function in the form of $y=ab^{x}$

First find the value of a and b if x=0 and y=19

$y=ab^x\\\\19=ab^0\\\\\\19=a*1\\\\\\19=a$

Find the value of b in $y=ab^x$

where x=6,y=1216 and a=19

$1216=19b^6\\\\\\1216/19=b^6\\\\\\64=b^6\\\\\sqrt[6]{64} =b\\\\2=b$

The function is $y=19*2^x$

If the perpendicular bisector of one side of a triangle goes through the opposite vertex, then is the triangle isosceles?

Ne4ueva [31]

Answer:

True

Step-by-step explanation:

The perpendicular bisector of the opposite side to the vertex bisects the angle at the vertex into two equal parts and also bisects the triangle into two equal parts.

Let A be the angle at the vertex, then assume that the angle is an isosceles triangle with base angles B.

We need to show that A = 180 - 2B for an isoceles triangle

The perpendicular bisector bisects A into two so the new angle in the vertex one half of the bisected triangle is A/2.

Since this half triangle is a right-angled triangle, the third angle in it is 90.

So, A/2 + B + 90 = 180 (Sum of angles in a triangle)

subtracting 90 from both sides, we have

A/2 + B + 90 - 90 = 180 - 90

A/2 + B = 90

subtracting B from both sides, we have

A/2 + B = 90

A/2 = 90 - B

multiplying through by 2, we have

A = 2(90 - B)

A = 180 - 2B

Since A = 180 - 2B, then our triangle is an isosceles triangle.

Suppose you have to use right-triangle trigonometry to find the apothem of a regular polygon. Which is greater, the apothem or t

asambeis [7]

The apothem represents one side of the right triangle to be solved. Specifically, it represents the height of the triangle.
The radius of the polygon represents the hypotenuse of the right triangle that is going to be solved.
Therefore, we can infer that the radius of the polygon is greater than the apothem because the hypotenuse is greater than all sides of a triangle.
Answer:
the radius of the polygon is greater
