Answer:

B,48.2

Step-by-step explanation:

To solve this we need to use SOH, CAH, TOA

we have the adjacent and hypotonouse so it's easiest to use CAH

let theta (angle) = x

cos(x)=4/6

to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)

x=48.1896851

which rounds to 48.2

Answer:

56

Step-by-step explanation:

Zoe and Hannah shared tips in the ratio

3:7

Last week Zoe received $24

Hence the amount received by Hannah can be calculated as follows

3/7= 24/x

168= 3x

x= 168/3

= 56

Hence Hannah received €56

Answer:

B

Step-by-step explanation:

Answer:

[tex]y = 2x - 5[/tex]

Substitute the value of y as 2x - 5 in the equation.

[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]

Now, find the value of y

[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]

⎇ x = x = x, equals 10

⎇ y = y = y, equals 15

Answer:

if y = 2x-5

then in the second equation we can find the value of x

5x-4(2x-5) = -10

5x-8x+20 = -10

-3x = -30

x = 10

then the value of y = 20-5 = 15

therefore the value of x = 10 and y =15 (ans)

Answer:

odd; even; even; odd

Step-by-step explanation:

The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We know when the graph is symmetric about the origin it is an off function.

When the graph is symmetric about the y axis it is an even function.

When f(-x) = f(x) it is an even function

When f(-x) = -f(x) it is an odd function.

Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

Answer:

2nd: 2

4th: -4

11th: -25

Step-by-step explanation:

When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:

A(2) = 5 + (2 - 1)(-3)

A(2) = 5 + (1)(-3)

A(2) = 5 - 3

A(2) = 2

To get the 4th term you substitute in 4:

A(4) = 5 + (4 - 1)(-3)

A(4) = 5 + (3)(-3)

A(4) = 5 - 9

A(4) = -4

And we do the same for the 11th term:

A(11) = 5 + (11 - 1)(-3)

A(11) = 5 + (10)(-3)

A(11) = 5 - 30

A(11) = -25

The behavior of the graph of the function y = -x^3 - 5x^2 - 3x + 9 at each of its zeros is as follows:

At x ≈ -4.919 and x ≈ -0.488, there are local minima.

At x ≈ 1.752, there is a local maximum.

Let's analyze the behavior of the graph of the function y = -x^3 - 5x^2 - 3x + 9 at each of its zeros in more detail.

To find the zeros of the function, we need to solve the equation -x^3 - 5x^2 - 3x + 9 = 0.

To simplify the calculations, let's use a numerical method like the Newton-Raphson method to approximate the zeros. We'll start with initial guesses and iteratively refine them to improve the accuracy of the solutions.

Initial guess: x_0 ≈ -5

Applying the Newton-Raphson method:

x_1 = x_0 - f(x_0) / f'(x_0)

where f(x) = -x^3 - 5x^2 - 3x + 9

f'(x) = -3x^2 - 10x - 3 (derivative of f(x))

x_1 = -5 - (-5^3 - 5(-5)^2 - 3(-5) + 9) / (-3(-5)^2 - 10(-5) - 3)

≈ -4.919

Initial guess: x_0 ≈ -1

Applying the Newton-Raphson method:

x_1 = x_0 - f(x_0) / f'(x_0)

x_1 = -1 - (-1^3 - 5(-1)^2 - 3(-1) + 9) / (-3(-1)^2 - 10(-1) - 3)

≈ -0.488

Initial guess: x_0 ≈ 2

Applying the Newton-Raphson method:

x_1 = x_0 - f(x_0) / f'(x_0)

x_1 = 2 - (2^3 - 5(2)^2 - 3(2) + 9) / (-3(2)^2 - 10(2) - 3)

≈ 1.752

After iterating through the Newton-Raphson method, we approximate the zeros as follows:

x ≈ -4.919

x ≈ -0.488

x ≈ 1.752

Now, let's analyze the behavior of the graph at each zero:

x ≈ -4.919:

When x is close to -4.919, y is close to zero. Since the coefficient of the leading term (-x^3) is negative, as x approaches -4.919 from the left side, the graph of the function will be decreasing. As x approaches -4.919 from the right side, the graph will be increasing. Therefore, the behavior of the graph near x ≈ -4.919 is a local minimum.

x ≈ -0.488:

When x is close to -0.488, y is close to zero. Similarly, as x approaches -0.488 from the left side, the graph will be decreasing, and as x approaches -0.488 from the right side, the graph will be increasing. Therefore, the behavior of the graph near x ≈ -0.488 is also a local minimum.

x ≈ 1.752:

When x is close to 1.752, y is close to zero. In this case, as x approaches 1.752 from the left side, the graph will be increasing, and as x approaches 1.752 from the right side, the graph will be decreasing. Therefore, the behavior of the graph near x ≈ 1.752 is a local maximum.
