You are sitting at the edge of the Grand Canyon admiring the view when you notice a tour group at the bottom of the canyon. You
ololo11 [35]

Answer:

7949.13 feet

Step-by-step explanation:

We are given that,

Angle of depression from the spot to the group = 39°

Height of Grand Canyon = 5000 feet.

So, we will get the following figure of a right triangle.

<em>As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.</em>

We get, \sin A=\frac{perpendicular}{hypotenuse}

i.e. \sin 39=\frac{5000}{x}

i.e. x=\frac{5000}{\sin 39}

i.e. x=\frac{5000}{0.629}

i.e. x = 7949.13 feet

Thus, the line of sight distance is 7949.13 feet.

Consider the graph of the expotential function y= 3(2)^x
victus00 [196]

Answer:

<h2>y-intercept = 3</h2><h2>x-intercept - not exist</h2><h2>the graph is increasing</h2>

Step-by-step explanation:

The exponential function:

f(x)=b(a)^x

has y-intercept for x = 0

hasn't x-intercept

if a > 1, then is increasing

if 0 < a < 1, then is decreasing

We have

y=3(2)^x

a = 2 >1 - increasing

for x = 0:

y=3(2)^0=3(1)=3
