Even means g(-x)=g(x)
replace x with -x and see if it simplifies to original functin
g(-x)=(-x-1)²+1
g(-x)=((-1)(x+1))²+1
g(-x)=(x+1)²+1
nope
g(x)=2x²+1
g(-x)=2(-x)²+1
g(-x)=2x²+1
yep
we are done
answer is 2nd one
The amount an investment of 16000 grows over 7 years is 16000*0.12 (i.e., 12% of 16000). So, the total amount after 7 years is 16000 + 16000*0.12, which is the same as writing 16000*1.12. Now, continue the same argument: the amount we now have 16000*1.12 grows after another 7 years to (16000*1.12)*1.12. Third 7-year period, again, (16000*1.12*1.12*)*1.12, and so on. As you can already see the number of periods shows up as the number of factors 1.12 multiplied here. A shorthand for writing that is to use the exponent, like this .
Generalizing to n 7-year periods yields a formula:
Answer:
When subtracts fractions with the same denominator, you only have to subtract the numerator.
5/9-3/9=
The denominators are the same, you just have to subtract the denominator. So in this case, you would only need to subtract 5-3. Therefore the answer would be 2/9. (Simplify if needed.)
Hope this Helps!
Ok to find the volume, you have to multiply the length•width•height. So, you would multiply 9.6•5•7 to get 11,760.
