1. Angle LKM and Angle JKM are supplementary 1. LJ is a straight line, since K is a midpoint
2. LK = KJ 2. K is a midpoint
3. Angle L + Angle M + Angle LKM = Angle LKM + Angle MJK 3. A triangle's total degrees is equal to the total degrees of two supplementary angles.
4. Angle JKM = Angle L + Angle M 4. Simple Algebra: Subtract Angle 
5. LK = KM 5. MK is intersecting LJ at a midpoint.
6. Triangle LKM is isoceles 6. Two of three sides and angles are equal.

Which of the following exponential functions goes through the points (1, 12) and (2, 36)?
Savatey [412]

Answer:

The function through which given point passes is f(x) = 24 x - 12 .

Step-by-step explanation:

Given as :

The points are

x_1 , y_1 = 1 , 12

x_2 , y_2 = 2 , 36

now, slope of the line

Let The slope of line = m = \frac{y_2-y_1}{x_2-x_1}

Or, m = \frac{36 - 12}{2-1}

Or, m = 24

So The slope of line = m = 24

<u>Now, equation of line in point-slope form</u>

y - y_1 = m × (x - x_1 )

Or, y - 12 = 24 × (x - 1 )

or, y - 12 = 24 x - 24

or, y = 24 x - 24 + 12

or, y = 24 x - 12

or , f(x) = 24 x - 12

So, The function through which given point passes is f(x) = 24 x - 12 . Answer

Write in standard form
Natalka [10]

Answer:

2.988*10^8

Step-by-step explanation:

to do standard form you have to  move the decimal to after the first number so in this case we would move the decimal 8 places from 298800000.0

to 2.98800000 and we can remove the zeros to make it 2.988

then you will plug the times ten and because we move the decimal over 8 it would be 10 to the power of 8 so your answer would be 2.988*10^8

hope this helps have a good day
