Answer:
D) Wanda will receive $23.50 for her share, meaning she lost $1.50 on the investment.
Step-by-step explanation:
Identify what you know:
1) Wanda bought a single share in Tasty Ice Cream for $25.00 on March 1st.
2) Tasty Ice Cream's stock price dropped to $23.50 (-1.50).
When investing in the stock market, you are always attempting to make a profit. So, you buy a stock when it's "low," and buy it when the prices go up. In reality, Wanda shouldn't sell her share yet, because she will lose $1.50. However, there is nothing stopping her, if she wanted to. Since the share is worth $23.50, Wanda will make $23.50 if she sells her share on June 13th.
Let x = length of the park
Let y = width of the park
Because the area is 392392 ft², therefore
xy = 392392 (1)
Because three sides of fencing measure 5656 ft, therefore
2x + y = 5656 (2)
That is
y = 5656 - 2x (3)
Substitute (3) into (1).
x(5656 - 2x) = 392392
5656x - 2x² = 392392
2x² -5656x + 392392 = 0
x² - 2828x + 196196 = 0
Solve with the quadratic formula.
x = (1/2)*[2828 +/- √(2828² - 4*196196)]
= 2756.83 or 71.17
Answer:
The possible dimensions are 2756.8 ft and 71.2 ft (nearest tenth)
"A parabola is curved instead of linear, in your case it is probably just facing up or down so I won't get into square roots for now.So the quadratic equation that you probably have had to memorize (or will soon) is:
x=(-b[+or-]√(b²-4ac))/2a when you have an equation like ax²+bx+c=0Now where does the curve shape come from? You see that little pesky plus or minus in the equation? That's because there are always 2 values (inputs) that will generate the same output. Example:y=x²(2)²=4(-2)²=...4So if you were to follow this pattern, and plot the points on a graph, you would end up with a curve. You end up with a curve because the slope is constantly increasing.
And this is actually where you start the study of Calculus(!), which is all about measuring slopes (And a bunch of other stuff, but this is the easiest part to explain). Actually, in this case of y=x², the slope at any given point (funnily enough) is equal to 2 times your x-value.
The point is, your line is curved because unlike a linear equation, the slope is changing (at a constant rate)."
Answer:
x = 18
Step-by-step explanation:
2/3 x = 12
x = 12 × 3/2
x = 6 × 8
x = 18
