Answer:
Step-by-step explanation:
Since the candy bar is just one
Giving 1/4 of it to her younger sister make her left with 3/4 of the candy bar i.e 1 - 1/4 = 3/4
Then giving 1/3 of the left over to her elder sister it becomes 3/4 * 1/3 =1/4
Then the remaining candy bar will be 3/4 - 1/4 = 1/2
Then she will be left with 1/2 i.e half of the candy bar.
Short answer
y >-x + 4
y <= 2(x - 1)^2 - 18

Let's establish what we are talking about. The question says purple and to me purple means the shaded area above the blue and to the upper right of the parabola.
Not so. It is the wine colored area right above the parabola according to the direction of he inequalities.
Second thing: the question is trying to see if you can read all he information you need from a graph.
Step One
Find the equation of the line.
We can read 2 points right away the x and y intercepts.
(4,0) is the x intercept
(0,4) is the y intercept
The general equation for the slope intercept equation is
y = mx + b So when x = 0 then b = y
4 = m*0 + b
b = 4
This far we have
y = mx + 4
when x = 4, y = 0
0 = m*4 + 4 Subtract 4 from both sides.
-4 = m*4 Divide by 4
-4/4 = m
m = - 1
Complete equation is y = -1x + 4
The inequality is y > -x + 4 Top answer block.
Step Two
Find the equation for the parabola
You could just read the minimum point which is (1,-18) There is a catch. (Isn't there always?) This may have a constant in front of the (x - a)^2 term. We'll check that out in the next step.
y = (x - 1)^2 - 18 is the basic vertex solution
Step Three
Find the value of a in
y = a(x - 1)^2 - 18
You have to do this because the answer has a space before the brackets. We need another point. The y intercept might work.
y = a(0 -1)^2 - 18
Use the point (0,-16)
-16 = a(1) - 18
-16 = a - 18 Add 18 to both sides.
2 = a
So the equation of the quadratic is
y <= 2(x - 1)^2 - 18 <<<<<< answer second section down on your question sheet.
Based on the fact that Duffs Co. dividends grow at 24% for three years and then 6%, the current share price of the company is $63.29.
<h3>What is Duffs Co. current price?</h3>
First, find the price of the stock in year 3 when the stock grows at 6%:
= (1.90 x 1.24³ x 1.06) / (0.11 - 0.06)
= $76.79
This amount is the terminal value. You are to take the present value of this amount along with the present value of the dividends up to year 3:
= ((1.90 x 1.24) / 1.11) + ((1.90 x 1.24²) / 1.11²) + ((1.90 x 1.24³) / 1.11³) + 76.79 / 1.11³
= $63.29
