Prove that the altitude to the base of an isosceles triangle is also the median to the base
QveST [7]

If altitude drawn from vertex A is also the median, the triangle is isosceles such that AB = AC and BC is the base. Hence this altitude is also the angle bisector. – If median drawn from vertex A is also the angle bisector, the triangle is isosceles such that AB = AC and BC is the base.

Explain why it makes sense for this situation to have a linear equation
IgorC [24]

Answer:

The line of best fit for your specific question is a linear equation.

Step-by-step explanation:

A linear equation has a constant rate of growth/decline and the growth/decline rate will never change in an linear equation.

If you draw a line that approximately splits between all the data plots, you will notice the line you drew is very close to the data points.

If the data plots was a quadratic, it would be very hard to draw a line of best fit.

Linear equations can easily be identified in a graph because it is a straight line.

Perhaps insert this equation into your graphing calculator or other graphing software online (like Desmos): y = 3x+2

A quadratic equation can also easily be identified in a graph because, in most cases, it looks like a U.

Take these examples: y = 3x^2+5x+2 or y=-2x^2+10x+30

What rational number equals 0.6 with bar over 6?
Neko [114]

when you dive the fractions

2/3 = 0.666666

6/10=0.6000

4/5 = 0.80

6/5 = 1.2

so the answer would be 2/3

Find the value of the following expression: (2^8 • 5^-5 • 19^0)^-2 • (5^-2 over 2^3)^4 • 2^28. Write your answer in simplified f
DaniilM [7]
Recognize that "( ) over 2^3" means ( ) • 2^-3. Use the rule of exponents
.. (a^b)^c = a^(b•c)

= 2^-16•5^10•19^-2 • 5^-8*2^-12 • 2^28

Now, you can use the rule of exponents
.. (a^b)*(a^c) = a^(b+c)

= 2^(-16 -12 +28) • 5^(10 -8) • 19^-2
= 5^2 • 19^-2
= 5^2 / 19^2
= 25/361
