Answer:
Step-by-step explanation:
1. 3.8 x 10^5 + 5.5 x 10^5 = 930,000 or 9.3 x 10^5
You just have to solve the equation and shorten the answer. For number one the answer is 930,000, so you have to make it into a number with decimals since a scientific notation number can not be equal to 10 or be greater. So you have to round the number to 9.3 not 93. To "round" it to 9.3 you have to move the decimal at the end of 930,000 to be in between the numbers 9 and 3. How many times you move the decimal to the left or right, that is the exponent of 10. So for 930,000 you moved the decimal 5 times to the left so the exponent for 10 is positive 5.
By making lines with an X and Y axis then add the numbers you need
To find the population after a year, you can multiply 4.5x10⁸ by 1.05, as it increases by 5% per year (1.05=1+5%). To find the population after five years, you have to multiply 4.5x10⁸ by 1.05 five times.
4.5x10⁸(1.05)⁵
=574326703.125
Since you can't have a decimal amount of people, you round this number to 574326703.
Therefore, the population after five years is going to be about 574326703.
Just like the Vertex Formula you do this:
y = 3(x - 4)³
This is where -H gives you the OPPOSITE terms of what they really are, and K gives you the NORMAL term, so just apply that to here. Whenever you are doing a phase shift, you put it in parentheses using the Vertex Formula, but giving the opposite term of what it really is:
Y = (X - H)² + K
Y = (X - H)³ + K
Now here is the graph. You see how I shifted it 4 units away from the origin?
So, find your roots [zeros (x-intercept)], plug in 0 for <em>y</em><em> </em>and solve for <em>x</em><em>.</em><em> </em>When you do this, you will get <em>4</em><em> </em><em>=</em><em> </em><em>x</em><em>.</em><em> </em>You could also look at the graph and can tell that the ONLY x-intercept is 4. So, either way, you will get the same result.

Answer:
26/52
0.5
50%
(diamond and heart suits)
Step-by-step explanation:
half of the cards in a standard deck are red. So, that'd 52/2 which is 26.
and since its half, you'd end up with .5 and 50%
hope this helps!!
