3^2.

Step-by-step explanation:

3^8 is common to numerator and denominator so it simplifies to:

Answer:

3² or 9

Step-by-step explanation:

Step 1: Add exponents

$\frac{3^{12}}{3^{10}}$

Step 2: Subtract exponents

You should get 3² because of exponent rules. Remember when you multiply exponents you add the powers and when you divide exponents you subtract the powers.

The endpoints of EF¯¯¯¯¯ are located at E (−3, 2) and F (3, 8). Point D divides EF¯¯¯¯¯ such that ED : DF is equal to 1 : 3. For

Answer:

$D(x,y) = (-1.5,3.5)$

Step-by-step explanation:

Given

$E = (-3,2)$

$F = (3,8)$

$ED: DF = 1 : 3$

Required

Determine the coordinates of D

This is calculated as thus:

$D(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

Where:

$(x_1,y_1) = (-3,2)$

$(x_2,y_2) = (3,8)$

$m:n = 1:3$

$D(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

$D(x,y) = (\frac{1 * 3 + 3 *-3}{1+3},\frac{1 * 8 + 3 * 2}{1+3})$

$D(x,y) = (\frac{-6}{4},\frac{14}{4})$

$D(x,y) = (-1.5,3.5)$

The drama club is selling tickets for a play. The profit, y, is

Goshia [24]

Answer:

80 tickets

Step-by-step explanation:

Given the profit, y, modeled by the equation, y = x^2 – 40x – 3,200, where x is the number of tickets sold, we are to find the total number of tickets, x, that need to be sold for the drama club to break even. To do that we will simply substitute y = 0 into the given the equation and calculate the value of x;

y = x^2 – 40x – 3,200,

0 = x^2 – 40x – 3,200,

x^2 – 40x – 3,200 = 0

x^2 – 80x + 40x – 3,200 = 0

x(x-80)+40(x-80) = 0

(x+40)(x-80) = 0

x = -40 and x = 80

x cannot be negative

Hence the total number of tickets, x, that need to be sold for the drama club to break even is 80 tickets
