Answer:
1
Step-by-step explanation:
Any thing to the power 0 will always be 1
x⁰=1
(3^-1=1/3)
(4^-1=1/4)
(5^-1=1/5)
1/3+1/4+1/5=47/60
(47/60)^0=1 (as any thing to the power 0 will always be 1 )
Hope this helps you.
<em>*It's debatable that there are 2 answers to this question because of how it's worded*</em>
For the first answer:
There would be 66 books left.
To get this, you need to multiply the original amount (120) by the decimal form of the percentage.
So, to get the decimal form you need to divide by 100, which essentially means you move the decimal 2 places to the left.
55% then becomes .55
So, 120 * .55 = 66
For the second answer:
If the question means that you need to decrease 120 by 55% <em>of 120 </em>then the answer would be 54.
120 - 66 = 54
So, depending on the answer choices and how it's interpreted, do what you will with this information.
Answer:
Option 2 and 5 are correct.
Step-by-step explanation:
We need to tell which one of them is quadratic function.
Option 1 is exponential decay so, it is not quadratic.
Option 2 is quadratic because the diver will take the parabolic shape when jumps.
Option 3 is not quadratic.Option 4 is not quadratic it is linear.
Option 4 is again exponential not quadratic.
Option 5 is quadratic because it takes the parabolic shape again.
