Hi!

You didn't list the options, but I think I know the answer. Let me know if my answer isn't listed! :)

(x^{3} )^{-5}
We need to multiply the exponents.
3 · -5 = -15

The answer is 2^{-15}

Hope this helps! :)

Identify the effect on the graph of replacing f(x) by A f(x)
JulijaS [17]

Answer:

See explanation

Step-by-step explanation:

Required

Effect of replacing f(x) with f(x - h)

f(x) is represented as: (x,y)

While

f(x - h) is represented as (x - h, y)

Notice the difference in both is that, the x value in f(x - h) is reduced by a constant h while the y value remain unchanged.

This means that the graph of f(x) will shift horizontally (i.e. along the x-axis) to the left by h units

Landon welded three pieces of metal together to form a triangle with side lengths that measure 8 inches, 9 inches and 17 inches.
Ray Of Light [21]

Answer:

<h3>No, it is not a right triangle</h3>

Step-by-step explanation:

In order to know whether the triangle is a right angle, we need to show that the square of the longest side is equal to the sum of the square of the other two sides

Longest side = 17in

other two sides = 8in and 9in

Check:

17² = 289

Sum of the square of other two sides

= 8² +9²

= 64 + 81

= 145

Since 17² ≠ 8² +9², hence the triangle that Landon created is not a right triangle

A camera is mounted at a point 4000 feet away from a geyser. If the water is rising vertically at 900 ft/s when it is 3000 feet
Leno4ka [110]

Answer:

\dot \theta = 0.144\,\frac{rad}{s}, \dot \theta = 8.251\,\frac{deg}{s} (Option B)

Step-by-step explanation:

The trigonometric diagram is included herein as attachment. The expression is presented below:

\tan \theta = \frac{y}{x}

Where:

x - Horizontal distance between the geyser and the camera.

y - Vertical distance between the geyser and the camera.

The rate of change in terms of time is:

\dot \theta \cdot \sec^{2}\theta = \frac{\dot y\cdot x-y\cdot \dot x}{x^{2}}

\dot \theta  \cdot \left(\frac{1}{\cos^{2}\theta} \right) = \frac{\dot y \cdot x - y\cdot \dot x}{x^{2}}

\dot \theta = \left(\frac{\dot y \cdot x - y \cdot \dot x}{x^{2}} \right)\cdot \cos^{2}\theta

\dot \theta = \left(\frac{\dot y \cdot x - y\cdot \dot x}{x^{2}} \right)\cdot \left(\frac{x^{2}}{x^{2}+y^{2}} \right)

\dot \theta = \frac{\dot y \cdot x - y\cdot \dot x}{x^{2}+y^{2}}

Finally,

\dot \theta = \frac{\left(900\,\frac{ft}{s} \right)\cdot (4000\,ft)-(3000\,ft)\cdot \left(0\,\frac{ft}{s} \right)}{(4000\,ft)^{2}+(3000\,ft)^{2}}

\dot \theta = 0.144\,\frac{rad}{s}

\dot \theta = 8.251\,\frac{deg}{s}
