How much money should the company spend on marketing each month?

o-na [289]

The function represents the profit, and the company obviously wants to maximize it.

You can see that the profit increases until the parabola reaches its maximum.

The coordinate of the maximum look like (1.5, 90)

This means that, if the company invests 1.5 thousand dollars, the profit will be 90 thousand dollars, and this is the maximum profit the company can reach.

At the halftime show, a marching band marched in formation. The lead drummer started at a point with coordinates (-2, -5) and mo

creativ13 [48]

Answer:

Part a) The rule of the translation is (x,y) -----> (x+1,y+3)

Part b) The coordinates of the drummer's final position are (-1,-2)

Step-by-step explanation:

Part a) Write a rule to describe the translation

we know that

The lead drummer moved 3 steps up and 1 step right.

so

3 steps up ----> that means (y+3)

1 step right ---> that means (x+1)

The rule of the translation is equal to

(x,y) -----> (x+1,y+3)

Part b) What were the coordinates of the drummer's final position?

we know that

The drummer's initial position is the point (-2,-5)

Applying the rule of the translation

(x,y) -----> (x+1,y+3)

(-2,-5) -----> (-2+1,-5+3)

(-2,-5) -----> (-1,-2)

therefore

The coordinates of the drummer's final position are (-1,-2)

Consider the graph of the quadratic function y = 3x2 – 3x – 6. What are the solutions of the quadratic equation 0 = 3x2 − 3x − 6

Ilya [14]

Roots of the equation 3x² -3x-6=0 are -1 and 2,
all choices are given wrong
3*2²-3*2-6=0
12-6-6=0
0=0, which is true , so root is 2

3*20²-3*20-6=0
600-60-6=0
534=0 which is wrong, so root is 2, but not 20
