Answer:

<h2>The number of Starbucks predicted in 2015 is 2697.</h2>

Step-by-step explanation:

There is an increment of 21% on yearly basis.

In 1982, the number of starbucks were 5.

In 1983, the number of starbucks will be 5\times \frac{121}{100}.

In 1984, The number will become 5\times\frac{121}{100} \times\frac{121}{100} = 5\times (\frac{121}{100} )^{2}.

In the year of X, the number of starbucks will be 5\times(\frac{121}{100} )^{t}, where t = X - 1982.

In 2015, t = 2015 - 1982 = 33.

The number of starbucks in 2015 is 5\times(\frac{121}{100} )^{33} = 2697.

What is an equation of the line that passes through the point<br> (-2,-8) and has a slope of 3?
nignag [31]

Answer:

y = 3x - 2

Step-by-step explanation:

Use the point-slope equation since we are given a point that the line passes through and its slope:

y - y1 = m(x - x1)

(-2, -8), m = 3

Substitute these values into the equation.

  • y - (-8) = 3(x - (-2))
  • y + 8 = 3(x + 2)
  • y + 8 = 3x + 6
  • y = 3x - 2

The equation of the line that passes through the point (-2, -8) and has a slope of 3 is y = 3x - 2.

what is the perimeter of the triangle. i do not know how to start this problem. any help will be greatly appreciated :))
xz_007 [3.2K]

Given:

Point F,G,H are midpoints of the sides of the triangle CDE.

FG=9,GH=7,CD=24

To find:

The perimeter of the triangle CDE.

Solution:

According to the triangle mid-segment theorem, the length of the mid-segment of a triangle is always half of the base of the triangle.

FG is mid-segment and DE is base. So, by using triangle mid-segment theorem, we get

\dfrac{1}{2}DE=FG

DE=2(FG)

DE=2(9)

DE=18

GH is mid-segment and CE is base. So, by using triangle mid-segment theorem, we get

\dfrac{1}{2}CE=GH

CE=2(GH)

CE=2(7)

CE=14

Now, the perimeter of the triangle CDE is:

Perimeter=CD+DE+CE

Perimeter=24+18+14

Perimeter=56

Therefore, the perimeter of the triangle CDE is 56 units.
