The law of cosine.

In Trigonometry, law of cosine (cos) is given by this mathematical expression:

cosθ = Opp/Hyp

Where:

Opp is the opposite side of a right-angled triangle.Hyp is the hypotenuse of a right-angled triangle.θ is the angle.

In this scenario, we can logically deduce that the student made an error in step 3. To correct this error, he should define side AY in terms of angle X.

explain how to calculate the x- and y- intercepts

Answers

The x-intercept is (16, 0) and y- intercept is (0, 6).

What is intercept?

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Given: 24x+64y=384

For y- intercept, put x=0

Then,

24*0+64y=384

64y= 384

y= 6

Now, for x- intercept put y=0

Then,

24x+64*0=384

24x= 384

x= 15

Hence, the x-intercept is (16, 0) and y- intercept is (0, 6).

Step-by-step explanation:

To determine if the graph is a function, we can use the vertical line test.

Determine whether each set of ordered pairs shown below is from a geometric sequence or from an arithmetic sequence.

Write the equation of the graph for the set of ordered pairs.

{(1, 150) , (2, 112.5) , (3, 84.375)}

Write the equation of the graph for the set of ordered pairs.

Answers

Using sequences concepts, it is found that:

The set of ordered pairs {(-3, 7.5) , (-2, 10) , (-1, 12.5)} is an arithmetic sequence with equation a(n) = 15 + 2.5d.The set of ordered pairs {(1, 150) , (2, 112.5) , (3, 84.375)} is a geometric sequence with [tex]a_n = 150(0.75)^{n-1}[/tex].

What is an arithmetic sequence?

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

[tex]a(n) = a(0) + nd[/tex]

The sequence {(-3, 7.5) , (-2, 10) , (-1, 12.5)} continues with points (0, 15), (1, 17.5), and so on, hence the first term and the common ratio are given, respectively, by:

a(0) = 15, d = 2.5.

Hence the equation is:

a(n) = 15 + 2.5n.

What is a geometric sequence?

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

For the sequence {(1, 150) , (2, 112.5) , (3, 84.375)}, the first term and the common ratio are given, respectively, by:

[tex]a_1 = 150, q = \frac{112.5}{150} = \frac{84.375}{112.5} = 0.75[/tex]

Hence the equation is given by:

[tex]a_n = 150(0.75)^{n-1}[/tex]

Here in the give problem that,

Point D lies on -6 in number line

Point E lies on 8 in number line

And F lies between D and E points and DE:EF = 3:1

So the point F clearly divides the staright line DE joining the point D at -6 and E at 8 in 3:1 ratio.

The speed of the current in a certain stream is 6 mph. If a boat travels 94 miles
downstream in the same time that it takes to travel 47 miles upstream, which best
describes the speed of the boat in still water?

Answers

The speed of the boat in still water is 18 mph.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

We know distance = speed×time.

Therefore, time = distance/speed.

Let, The speed of the boat at still water be 'x'.

Therefore, From the information,

94/(x + 6) = 47/(x - 6).

94(x - 6) = 47(x + 6).

94x - 564 = 47x 282.

47x = 846.

x = 18.

So, The speed of the boat is 18 mph in still water.

The piece-wise function is defined as follows:

What is a piece-wise function?

A piece-wise function is a function that has multiple definitions, depending on the input.

In this graph, for x at least 0 and less than 3, the parabolic curve passes through (0,0), (1,1), (2,4) and has an open interval at (3,9), hence the definition is:

[tex]f(x) = x^2, 0 \leq x < 3[/tex]

For x greater than 3 and at most 6, it is a line going through (3,9) and (6,4), hence:

[tex]m = \frac{9 - 4}{3 - 6} = -\frac{5}{3}[/tex]

[tex]f(x) = -\frac{5}{3}x + b[/tex]

Goes through (3,9), hence:

[tex]9 = -\frac{5}{3}(3) + b[/tex]

b = 14.

So

[tex]f(x) = -\frac{5}{3}x + 14, 3 < x \leq 6[/tex]

For x between 6 and 10, it is a line going through (6,4) and (10,10), hence:

[tex]m = \frac{10 - 4}{10 - 6} = \frac{6}{4} = \frac{3}{2}[/tex]

Then:

[tex]f(x) = \frac{3}{2}x + b[/tex]

When x = 10, f(x) = 10, hence:

[tex]10 = \frac{3}{2}(10) + b[/tex]

10 = 15 + b

b = -5.

Hence:

[tex]f(x) = \frac{3}{2}x - 5, 6 \leq x \leq 10[/tex]
