Answer:

18-32i^2

Step-by-step explanation:

3 + the negative square root of 16 would simplify to 4i

so it will be (3+4i)

6 - the negative square root of 64 would simplify into 8i

so it will be (6-8i)

To solve (3+4i)(6-8i) use FOIL and add like terms

Plus means addition and square root means √

3 plus the square root of negative 16: 3 + √-16

Minus means subtraction and square root means √

6 minus the square root of negative 64: 6 - √-64

Its asking you to multiply both quantities.

(3 + √-16) * (6 - √-64)

Best of Luck!

PLZ HELP NNOOOOOOOWW!! 15 points!!

The midpoint of the line having the endpoints (x_1,y_1) and (x_2,y_2) is (\frac{x_{1}+_x_{2}}{2}, \frac{y_{1}+_y_{2}}{2})
basically average them


so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2

so the midpoint can be found by doing
(\frac{-3+9}{2}, \frac{7+(-2)}{2})=
(\frac{6}{2}, \frac{7-2}{2})=
(3, \frac{5}{2})

the midpoint is (3,\frac{5}{2})

The ticket price which will maximize the student's council is: C. $3.10.

<h3>What is price?</h3>

Price can be defined as an amount of money which is primarily set by the seller of a product, and it must be paid by a buyer to the seller, so as to enable the acquisition of this product.

Based on the information provided about Valley High School student council, we can logically deduce the following data:

  • Total number of students = 420 students.
  • Lowest ticket price = $2.00.
  • Increase in ticket price = $0.20.
  • Attendance = 20 fewer students

<h3>How to determine the ticket price?</h3>

Mathematically, the equation which model the profit is given by:

Profit = price × number of tickets sold

P(x) = (2 + 0.2x)(420 - 20x)

P(x) = 840 + 84x - 40x - 4x²

P(x) = -4x² + 44x + 840.

For any quadratic equation with a parabolic curve, the axis of symmetry is given by:

Xmax = -b/2a

Xmax = -44/2(-4)

Xmax = -44/-8.

Xmax = 5.5

Ticket price for maximum profit is given by:

Ticket price = 2 + 0.2x

Ticket price = 2 + 0.2(5.5)

Ticket price = $3.10.
