Revenue flows into a company at a rate of f(t) = 3000 1 + 5t , where t is measured in years and f(t) is measured in dollars per
Igoryamba

Answer:

F = 388500\,dollars

Step-by-step explanation:

The revenue flows has the following function:

f(t) = 3000\cdot (1+5\cdot t)

The total revenue obtained in the first seven years is obtained by using the concept of definite integral:

F = 3000\int\limits^7_0 {(1+5\cdot t)} \, dt

F = 3000\cdot t|_{0}^{7}+7500\cdot t^{2}|_{0}^{7}

F = 21000+367500

F = 388500\,dollars

Tell whether the lines through the given points are parallel, perpendicular, or neither.
Nataly_w [17]

Step-by-step explanation:

The slope of a line connecting two points is:

m = (y₂ − y₁) / (x₂ − x₁)

The slope of line 1 is:

m = (4 − 0) / (7 − 1)

m = 2/3

The slope of line 2 is:

m = (6 − 0) / (3 − 7)

m = -3/2

Parallel lines have equal slopes.

Perpendicular lines have opposite inverse slopes.

2/3 and -3/2 are opposite inverses, so the lines are perpendicular.

Rectangle ABCD is rotated by 90 degrees clockwise about the origin then translated 3 units left and 2 units down to form A'B'C'D
timurjin [86]

The length in units of the line segment A'B' in the resulting figure is the same as the length of line segment AB in the previous rectangle.

<h3>Translation of shapes in the Cartesian plane</h3>

Form the task content;

  • It follows that the initial rectangle A is only translated and hence, the size of each of its sides remains constant.

The translation which occurs on the rectangle only shifts the whole rectangle leftward and downward and hence, each line segment in the rectangle still retains its length.
