Answer:
The standard form is: y = -3x² +18x -24.
Step-by-step explanation:
Given is y = -3(x-2)(x-4)
Using FOIL method to expand the parentheses:-
y = -3(x-2)(x-4)
y = -3(x² -2x -4x +8)
Combining like terms:-
y = -3(x² -6x +8)
Distributing -3 to the terms inside parentheses:-
y = -3x² +18x -24.
Hence, standard form is: y = -3x² +18x -24.
Answer:
b. $35.61
Step-by-step explanation:
First, convert the 25% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 25%) by 100%.So, the conversational term "25%" becomes 25% / 100% = 0.25 in terms of a real mathematical number.
Second, you need to find out what 25% of your $28.49 meal cost is.This is always done by multiplying 0.25 by $28.49, or
<h2> 0.25 x $28.49=$7.12.
</h2>
So, the amount of tip you are going to leave is $7.12.
This makes the total cost of your meal (to write on your charge slip or other payment)
<h2>
$28.49 + $7.12 = $35.61.
</h2>

Answer:
65,536
Step-by-step explanation:
Since there are no options, I would simply simplify the expression given.
One-sixteenth=
We want to determine an equivalent expression to 
Now, from laws of indices (i) 
(ii)
Therefore applying Rule (ii) above: = ![(\dfrac{1}{16})^{-1X4}=[(\dfrac{1}{16})^{-1}]^4](https://tex.z-dn.net/?f=%28%5Cdfrac%7B1%7D%7B16%7D%29%5E%7B-1X4%7D%3D%5B%28%5Cdfrac%7B1%7D%7B16%7D%29%5E%7B-1%7D%5D%5E4)
Using Rile (i),
Therefore ![[(\dfrac{1}{16})^{-1}]^4 =16^4=65536](https://tex.z-dn.net/?f=%5B%28%5Cdfrac%7B1%7D%7B16%7D%29%5E%7B-1%7D%5D%5E4%20%3D16%5E4%3D65536)
