Chemical reaction (I think)
Answer:
$2
Step-by-step explanation:
So, I am gonna go on a gander and say five. You would start by doing this.
5 * 6 = 30
Then you.
30 + 6 = 36
You will have two dollars left over.
Step-by-step explanation:
Q6
answer A, as x² is the regular parabolic curve up. and x²-3 just shifts this curve down by 3 units. and that is what we need, as the extreme point of the curve is a bit below the x-axis, and therefore has a negative y value.
Q7
answer C, as this curve is the complete opposite of the curve in Q6.
it is the regular parabolic curve but down. that means -x².
but the extreme point is a bit above the x-axis (and has therefore a positive y value). -x²+3 shifts the parabolic curve up by 3 units.
Q8
answer A again. the functional values are only positive (the whole curve is above the x-axis). so, C and D are therefore wrong.
and between A and B we need to remember, that a negative exponent means 1/...
in case of B 1/(2^x).
and that would mean for large positive x we would get very small values for y.
but we see the opposite. for large x we also get large y.
so, it is 2^x (answer A).
Answer:
80%.
Step-by-step explanation:
Given:
Last year Michelle adopter a pet rabbit sence it was adopted the rabbit weight has increased from 1 1/4 to 2 1/4.
Question asked:
By what percentage has the rabbit weight increased ?
Solution:
<u>As we know:</u>
<u />![Percentage\ increased=\frac{New\ value-old\ value}{old \ value} \times100](https://tex.z-dn.net/?f=Percentage%5C%20increased%3D%5Cfrac%7BNew%5C%20value-old%5C%20value%7D%7Bold%20%5C%20value%7D%20%5Ctimes100)
Old value =
New value = ![2\frac{1}{4} =\frac{4\times2+1}{4} =\frac{9}{4}](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B4%7D%20%3D%5Cfrac%7B4%5Ctimes2%2B1%7D%7B4%7D%20%3D%5Cfrac%7B9%7D%7B4%7D)
![Percent\ increased\ in\ weight=\frac{new\ weight-old\ weight}{old\ weight} \times100](https://tex.z-dn.net/?f=Percent%5C%20increased%5C%20in%5C%20weight%3D%5Cfrac%7Bnew%5C%20weight-old%5C%20weight%7D%7Bold%5C%20weight%7D%20%5Ctimes100)
![=\frac{\frac{9}{4}-\frac{5}{4} }{\frac{5}{4} } \times100\\ \\ =\frac{\frac{9-5}{4} }{\frac{5}{4} } \times100\\ \\ =\frac{\frac{4}{4} }{\frac{5}{4} } \times100\\ \\ =\frac{1}{{\frac{5}{4} } }\times100\\ \\ =\frac{4}{5} \times100\\ \\ =\frac{400}{5} \\ \\ =80\%](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cfrac%7B9%7D%7B4%7D-%5Cfrac%7B5%7D%7B4%7D%20%20%7D%7B%5Cfrac%7B5%7D%7B4%7D%20%7D%20%5Ctimes100%5C%5C%20%5C%5C%20%3D%5Cfrac%7B%5Cfrac%7B9-5%7D%7B4%7D%20%7D%7B%5Cfrac%7B5%7D%7B4%7D%20%7D%20%5Ctimes100%5C%5C%20%5C%5C%20%3D%5Cfrac%7B%5Cfrac%7B4%7D%7B4%7D%20%7D%7B%5Cfrac%7B5%7D%7B4%7D%20%7D%20%5Ctimes100%5C%5C%20%5C%5C%20%3D%5Cfrac%7B1%7D%7B%7B%5Cfrac%7B5%7D%7B4%7D%20%7D%20%7D%5Ctimes100%5C%5C%20%20%5C%5C%20%3D%5Cfrac%7B4%7D%7B5%7D%20%5Ctimes100%5C%5C%20%5C%5C%20%3D%5Cfrac%7B400%7D%7B5%7D%20%5C%5C%20%5C%5C%20%3D80%5C%25)
Thus, weight of rabbit increased by 80%.
