Answer:

height of the tower = 2358.3 feet

Step-by-step explanation:

To solve this question, we can use the tangent relation of the angle of elevation, where the opposite side of the angle is the height of the tower minus six feet and the adjacent side of the angle is the distance from David to the tower. So, we have that:

tangent(78) = (height - 6)/500

4.7046 = (height - 6) / 500

height - 6 = 2352.3

height = 2358.3 feet

Do you think this graph looks more like a quadratic or exponential function? Why do you think so?
pantera1 [17]

Answer:

Exponential Function

Step-by-step explanation:

The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.

This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:

f(x)=f(0)(2)^{x}

Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.

Write the equation of the line that passes through (2, 3) and is parallel to the line 12x – 5y = 2.
Alexeev081 [22]
         12x - 5y = 2
12x - 12x - 5y = -12x + 2
                 -5y = -12x + 2
                  -5          -5
                    y = 2.4x - 0.4
               y - 3 = 2.4(x - 3)
               y - 3 = 2.4(x) - 2.4(3)
               y - 3 = 2.4x - 7.2
                 + 3           + 3
                    y = 2.4x - 4.2
