Determine the interval(s) on which the given function is decreasing.
Gre4nikov [31]

A function is decreasing if, reading from left to right, we can see that the graph of the function goes down.

Here we can't see the graph, but we have a brief description.

"the graph goes up until it reaches a maximum at (0, 5), then the graph reaches a relative minimum at (1, 4), then it goes up again"

Now, the graph was going up until it reached the maximum, so at that point, the graph starts going down.

The graph will go downwards until it reaches the minimum, at that point the graph starts increasing again.

So the graph only goes down between x = 0 and x = 1.

we can conclude that the interval on which the given function is decreasing is [0, 1]

From a hot-air balloon, Brody measures a 39° angle of depression to a landmark
EleoNora [17]

The balloon's vertical distance above the ground is 430 feet.

<h3>What is the angle of depression?</h3>

You look straight parallel to the ground. But when you have to watch something down, then you take your sight down by moving your head up.

The angle from horizontal to the point where you stopped your head is called the angle of depression.

From a hot-air balloon, Brody measures a 39° angle of depression to a landmark that's 532 feet away, measuring horizontally.

The angle of depression = 39°

The base = 532

We need to find the vertical distance consider perpendicular.

\rm Tan \theta = \dfrac{perpendicular}{base } \\\\\rm Tan 39 = \dfrac{perpendicular}{532} \\\\\rm Tan 39 \times 532 =perpendicular\\\\0.80 \times 532\\\\P = 430.80

Therefore, the balloon's vertical distance above the ground is 430.80 feet.

8 squared plus 9 left parenthesis 12 divided by 3 times 2 right parenthesis minus 7. Explain each of your steps.
vekshin1

Answer:

129

Step-by-step explanation:

PEMDAS (parenthesis, exponents, multiplication / division, addition /subtraction.) I will use these as abbreviations.

8^2 + 9 (12/3*2) - 7

P: Start with P, and inside P go left to right with M/D

    D: 8^2 + 9 (4*2) - 7

    M: 8^2 + 9 (8) - 7

E: The next step is E, so I will do 8^2

64 + 9 (8) - 7

M/D: I will then multiply from left to right

64 + 72 - 7

A/S: Finall I will add and subtract from left to right.

   A: 136 - 7

   S: 129

hello I need help with question 2 attached is the tables created in question one which I need to base question 2 off of. 2. Find
Vadim26 [7]

The given functions are:

\begin{gathered} f(x)=3x+2 \\ g(x)=\frac{x-2}{3} \end{gathered}

The domain is the set of all possible values that the independent variable (x) can take.

The range is the set of values that the function will take.

For these functions, the domain is all real numbers since they both will work with any positive or negative number (-∞,∞). Thus, the range is the same, all real numbers (-∞,∞).

But, for the purpose of the question let's analyze the interval you took for the table of values:

For f(x) function, you take x-values from -3 to 3, then the domain in this interval is [-3,3] and the range is the output values (f(x)), then the range is [-7,11].

For g(x) function, you take x-values from -7 to 11, then the domain in the interval is [-7,11] and the range (the g(x) values obtained) is [-3,3].

As can be noticed, in the interval the domain of the f(x) functions is the same as the range of the g(x) function, and the domain of the g(x) function is the same as the range of f(x) function. This happens because g(x) is the inverse function of f(x).
