A ladder leans against the side of a house. The angle of elevation of the ladder is 64 degrees
ValentinkaMS [17]

Answer:

The length of the ladder is 14.5 ft

Step-by-step explanation:

For a right triangle

sinx = opposite / hypotenuse

Since we know the angle and the opposite side, we can calculate the hypotenuse

sin 64 = 13/ hypotenuse

Multiply each side by the hypotenuse

hypotenuse * sin 64 = 13

Divide by sin 64

hypotenuse = 13/sin 64

hypotenuse=14.4638

Rounding to the nearest tenth

14.5

Which set of ordered pairs could be generated by an exponential function ?
lawyer [7]

Answer:

The third choice is the correct answer

Step-by-step explanation:

The set of ordered pairs which could be generated by an exponential function is

(1,\frac{1}{2}),(2,\frac{1}{4}),(3,\frac{1}{8}),(4,\frac{1}{16})

If we examine the y-values of this set of ordered pairs, we can see that they have a common ratio of

r=\frac{1}{4}\div \frac{1}{2}

r=\frac{1}{4}\times 2

r=\frac{1}{2}

This makes it exponential.
