Answer:

149.43 feet tall

Step-by-step explanation:

From the base of a large tree, a bird watcher is standing 50 feet away.

There is 71.5° of elevation from the bird watcher to a bird on the top of the tree.

If we ignore the height of the observer and consider the height of the tree as h feet, then using trigonometry we can write that

tan 71.5° = \frac{h}{Base} = \frac{h}{50}

Hence, h = 50 tan 71.5° =149.43 feet.

Therefore, the tree is 149.43 feet tall. (Answer)

Hello there can anyone solve this plz (chart is attached):

Answer:

h^\prime(1)=14

Step-by-step explanation:

We have the function:

h(x)=f[f(x)]

And we want to find:

h^\prime(1)

So, we will differentiate function <em>h</em>. By the chain rule, this yields:

h^\prime(x)=f^\prime[f(x)]\cdot f^\prime(x)

Then it follows that:

h^\prime(1)=f^\prime[f(1)]\cdot f^\prime(1)

Using the table, we acquire:

h^\prime(1)=f^\prime(3)\cdot2

And using the table again, we acquire:

h^\prime(1)=7\cdot 2

Evaluate. Hence:

h^\prime(1)=14

Look carefully at the triangle solve for x ​
luda_lava [24]

The 3 inside angles of a triangle need to equal 180 degrees. Looking at the larger outside triangle the top angle is 30 and the lower right angle is 60.

30 + 60 = 90

The lower left angle needs to be 180 - 90 = 90 degrees.

That angle is split into two angles with one given as 70.

This means X needs to be 90 - 70 = 20 degrees.

x = 20

Do the functions have the same concavity?
Vesna [10]

Answer:

Step-by-step explanation:

Function f is graphed. The positive x-axis contains point c. The graph consists of an N-shaped curve. The curve starts in quadrant 3, moves upward concave down to a point in quadrant 1, moves downward concave down to point c in quadrant 1, continues downward concave up to a point in quadrant 4, moves upward concave up and ends in quadrant 1. The curve is purple to the left of point c, where it is concave down, and is green to the right of point c, where it is concave up.

Notice how fff is \purpleC{\text{concave down}}concave downstart color #aa87ff, start text, c, o, n, c, a, v, e, space, d, o, w, n, end text, end color #aa87ff to the left of x=cx=cx, equals, c and \greenD{\text{concave up}}concave upstart color #1fab54, start text, c, o, n, c, a, v, e, space, u, p, end text, end color #1fab54 to the right of x=cx=cx, equals, c.

f, start superscript, prime, prime, end superscript.

Function f double prime is graphed. The x-axis goes from negative 8 to 8. The graph consists of a wave-shaped curve. The curve starts at (negative 8, 0), moves downward concave up to (negative 5, negative 5), moves upward concave up to (negative 2, 0), continues upward concave down t
