State if the product of rational numbers and integer is an integer
The statement is false and the proof is as follows
Literally, rational numbers are decimal numbers that can be represented as a fraction of two integers;
Take for instance: 0.2, 0.5, 2.25, etc.
When any of these numbers is multiplied by an integer, the resulting number can take any of two forms;
1. It can result to an integer:
<em>For instance;</em>
2. It can result in a decimal number
<em>For instance;</em>
From (1) above, we understand that the product can result in an integer.
Hence, the statement is false
If my math is right it should be b
The compounded interest function that models the situation is:
where
is the final amount of money after
years.
is the initial investment.
is the interest rate in decimal form.
is the number of times the interest is compounded per year.
is the time in years.
We know for our problem that
and
. To convert the interest rate to decimal form, we are going to divide the rate by 100%:
We also know that the interest is compounded anally, so it is compounded 1 time per year; therefore,
.
Lets replace the values in our formula to find the final amount after 8 years:
We can conclude that since we are dealing with compound interest we must use the function
. Also, after 8 years the balance in the account will be $1291.58
If you use the distributive property and multiply -22 by x and 2 you will come out with y+5= -22x-44. Then subtract 5 and it would cancel out and you subtract it from the -44. -44-5 is equal to -49. So your equation would be y= -22x-49. This means that your slope would be -22.
The general vertex form equation of the parabola is
The Axis of Symmetry is given by
x=h
For the given equation the Equation of the Axis of symmetry for the parabola y=1/2(x-3)^2+5 as x=3.
