Answer:
68 is what I'm getting for x
70 is the correct length of DH
Step-by-step explanation:
You can set up the proportion for this question.
99.2 / 62 = 112/(x + 2) Cross multiply
99.2 ( x + 2) = 62 * 112 Combine the right side
99.2(x + 2) = 6944 Use the distributive principle to remove the brackets.
99.2*x + 2*99.2 = 6944 Combine the factors on the left
99.2x + 198.4 = 6944 Subtract 198.4 from both sides
99.2x = 6944 - 198.4 Combine the terms on the right
99.2x = 6745.6 Divide both sides by 99.2
x = 6745.6/99.2
x = 68
DH = 70
Assuming the function is
f(x) = x^4 + 3x^3-28x^2
Factorising, we get
f(x) = x^2(x+7)(x-4)
Therefore, there is a double root at x = 0 and singular roots at x = -7 and 4
double roots tend to bounce, kind of like the standard quadratic y = x^2
singular roots tend to cross, kind of like a straight line on a graph, y = mx + b
Therefore, it bounces at x = 0, and crosses at x = -7 and 4
In general, a root raised to an even power bounces, and a root raised to an odd power crosses.

Answer:
$13,087.50
Step-by-step explanation:
The sale of the 40 shares of stock A at $225 per share will get Juan ...
40 · $225 = $9000
The sale of the 150 shares of stock B at $27.25 per share will get Juan ...
150 · $27.25 = $4087.50
So, the total Juan will receive from the sale of the stocks will be ...
$9000.00 +4087.50 = $13,087.50
