My parents being away from home for a long period of time would most likely strengthen our bond when they returned home. During the time they were away, I would realize how truly important they are to me.
The capital of Poland is Warsaw.
Answer:
64
Explanation:
The question is incomplete without the expression that would be used to find the constant necessary to make a perfect square trinomial.
I would show you how to find the constant necessary to make a perfect square trinomial using the expression below:
x² - 16x + c
The expression above is in the form of a quadratic: ax² + bx + c
Where a = 1, b = -16, c = constant
First thing we do, is to square half the coefficient of x
Coefficient x above = b = -16
square of half the coefficient of x = (-16/2)²
Expand it, we have = -16/2 × -16/2 = 8×8 = 64
Replace the constant with 64
x² - 16x + 64
b/2 = -16/2 = -8
(x - 8)² will give a perfect square trinomial
Therefore the constant which makes the above expression a perfect square trinomial is 64
Answer and Explanation:
We are shown that the line HF is equal to line that has a length of 9x + 1.
If we can solve for x, we can find what the length of GF is.
<u>Set the lines equal to each other.</u>
7 + 3x = 9x + 1
<u>Subtract 3x from both sides.</u>
7 = 6x + 1
<u>Subtract 1 from both sides.</u>
6 = 6x
<u>Divide both sides by 6.</u>
x = 1
<u>Plug 1 in for x.</u>
3(1) = 3
<u>GF = 3</u>

You have to look at the arrival time between the P and S waves. it looks like they already did it for you here. the answer is 1035 km.
I drew a couple extra lines to show you in more detail.
Let's say for example our p-wave arrived at t=4min and our s wave arrived at t=6.5 min. The time difference is 2.5 min. So you can either plot 4 and 6.5 and draw a line straight across like I did (green line and dotted green) or find the spot where the distance between the two lines is t = 2.5 min. We see the epicentral distance for the green line is about 1800km.
Try the yellow line yourself. you should get t values of about 4.5 and 8.5 at an epicentral distance of 2600km.
