Answer:
It's 1,000
Step-by-step explanation:
exponential form is f(x)= a × b^2
(a=initial amount)
(b=growth rate)
you would replace a for 1000 and b for .06 (+1)
v(t)=1000(1.06)^2t
therefore the initial amount is 1000
if this didnt help sorry lol
Find the median of the following data:<br>
10,16, 15, 14, 8, 21, 10, 5, 19, 18, 4, 5, 16, 12, 10,9

Answer:
The median is 11.
Step-by-step explanation:
First arrange the data in ascending order:
4, 5, 5, 8, 9 , 10, 10, 10, 12, 14, 15, 16, 16, 18, 19, 21
There are 16 numbers so the median is the mean of the middle 2 numbers in the list. That is the mean of the 8th and ninth number.
Median = 10 + 12 / 2
= 11.

Answer:
∠HIJ = 57
∠IJH = 57
∠JHI = 66
Step-by-step explanation:
As a much better answer to the other guy:
You first have to find what the sum of the interior angles are. This can be found using the following expression:
<em>( n - 2 ) × 180</em>
Where 'n' is the number of sides of a polygon. Since this is a triangle:
<em>n = 3</em>
Therefore, the sum the interior angles of a triangle is 180°
Returning to the triangle, it's stated that the <u>triangle is isosceles,</u> meaning the ∠HIJ is the same as the ∠IJH (the middle point notating the position of the angle.) So then you have 3 angles with the following expressions:
∠HIJ = 5x + 2
∠IJH = 5x + 2
∠JHI = 3x + 33
Since all of the angles need to add up to 180°, we can smush them all into one big equation:
5x + 2 + 5x + 2 + 3x + 33 = 180
If you simplify everything:
13x + 37 = 180
Subtract 37:
13x = 143
Divide by 13:
x = 11
Now that you have x, plug it in to the equations above!
∠HIJ = 5(11) + 2
∠IJH = 5(11) + 2
∠JHI = 3(11) + 33
Simplify.
∠HIJ = 55 + 2
∠IJH = 55 + 2
∠JHI = 33 + 33
Again.
∠HIJ = 57
∠IJH = 57
∠JHI = 66
There you go!
i I guess this will help you a little
