3. Blackberry is also in the business of selling phones. The data for the profit that Blackberry makes on selling tablets is rep

resented by the following equation with profit being P(b) and b being number of blackberry phones sold (both variables in millions):
P(b) = -x2 + 8x – 8

a. Use the quadratic formula to solve the equation. What do these points tell us about the graph?




b. Complete the following table. Based on the table, estimate the vertex for the function. Is the vertex a max. or a min. point?

natta225 [31]

Answer:

Barry has to pay back $1150

Step-by-step explanation:

We can set up an equation to help solve this problem

x is the amount he has to pay back

x=1000+3(1000/20)

1000/20 lets us know how many times he borrowed 20 dollars

x=1000+3(50)

x=1000+150

x=1150

Barry has to pay back $1150

The area of the shaded triangles in the fractal shown form a geometric sequence. The area of the largest triangle (not shaded) i
guajiro [1.7K]

Answer:

The correct answers are Blue: \frac{1}{16} square units ; Green:  \frac{1}{64} square units; and Yes the sum converges.

Step-by-step explanation:

Area of the largest triangle is 1 square unit.

The area of the triangle which are colored and follow a geometric sequence with the common ratio being \frac{1}{4}.

Area of the not shaded triangle is given by 1 square unit.

Area of the orange triangle is given by 1 × \frac{1}{4} = \frac{1}{4} square units.

Area of the blue triangle is given by \frac{1}{4} × \frac{1}{4} = \frac{1}{16} square units.

Area of the green triangle is given by \frac{1}{16} × \frac{1}{4} = \frac{1}{64} square units.

If the pattern continues definitely then it becomes an infinite geometric progression series with common ratio \frac{1}{4}. And thus the sum of area coverges as the ratio lies between -1 and 1.
