39. Tugboat A and Tugboat B are pulling a barge. Each tugboat is connected to the barge via a
cable. If the length of the cables are 72 meters and 77 meters and the tugboats are 35 meters
apart, find the angle formed between the cables.

Answers

Answer:

[tex]26.903^{\circ}[/tex]

Step-by-step explanation:

a = 77 m

b = 72 m

c = Distance between the tugboats = 35 m

[tex]m\angle C[/tex] = Angle between the cables

[tex]c^2=a^2+b^2-2ab\cos C\\\Rightarrow m\angle C=\cos^{-1}\dfrac{c^2-a^2-b^2}{-2ab}\\\Rightarrow m\angle C=\cos^{-1}\dfrac{35^2-77^2-72^2}{-2\times 77\times 72}\\\Rightarrow m\angle C=26.903^{\circ}[/tex]

The angle formed between the cables is [tex]26.903^{\circ}[/tex].

Part A
Based on the graph, how many zeros does the polynomial function, f(x) = -x^4 - 3x^3 + 6x^2 + 8x have?


Part B

What are the zeroes of the above polynomial function?

A. -4,0,2,3
B. 0, 2 only
C. -4,-1, 0, 2
D. -4, 2 only

Answers

Answer:

Part A: There are 4 zeros of the polynomial function f(x)

Part B: The zeroes of the polynomial function f(x) are -4, -1, 0, 2C

Step-by-step explanation:

The zeroes of a function are the x-coordinates of the point of intersection between the graph of the function and the x-axis (x-intercepts) which means values of x at y = 0

Part A:

In the given graph

∵ The graph of the function f(x) = -[tex]x^{4}[/tex] - 3x³ + 6x² + 8x intersects the x-axis

   at 4 points

→ That means there are 4 values of x have y = 0

∴ The number of zeroes of the function is 4

There are 4 zeros of the polynomial function f(x)

Part B:

∵ The graph intersects the x-axis at points (-4, 0), (-1, 0), (0, 0), (2, 0)

→ That means the values of x at y = 0 are -4, -1, 0, 2

∴ f(x) = 0 at x = -4, -1, 0, 2

The zeroes of the polynomial function f(x) are -4, -1, 0, 2

Answer:

Option C

Step-by-step explanation:

Difference of the two expressions has been written as,

[tex]\frac{3x}{x^2-7x+10}-\frac{2x}{3(x-5)}[/tex]

To rewrite this expression as one expression,

First he factored the the denominators,

[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x}{3(x-5)}[/tex]

Then Juan will make the denominators of both the terms equal,

For which he will multiply the second expression by [tex]\frac{x-2}{x-2}[/tex].

[tex]\frac{3x}{(x-2)(x-5)}-\frac{2x(x-2)}{3(x-5)(x-2)}[/tex]

What is the slope-intercept equation of the line that is perpendicular to y-4=-2/3(x-6) and that passes through (-2, -2)?

Answers

Answer:

The slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Step-by-step explanation:

Given the equation

[tex]y-4=-\frac{2}{3}\left(x-6\right)[/tex]

comparing it with the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

so the slope of the line is -2/3.

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 3/2

The point-slope form of the equation of the perpendicular line that goes through (-2, -2) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-2\right)=\frac{3}{2}\left(x-\left(-2\right)\right)[/tex]

[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]

writing the line equation in the slope-intercept form

[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]

subtract 2 from both sides

[tex]y+2-2=\frac{3}{2}\left(x+2\right)-2[/tex]

[tex]y=\frac{3}{2}x+1[/tex]

Thus, the slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Here,

As the slope-intercept form is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

so

[tex]y=\frac{3}{2}x+1[/tex]

m=3/2

b = y-intercept = 1

Therefore, the slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Write y - 2 =- 1/3(x + 6) in standard form using integers.

Answers

Answer:

x+3y=0

Step-by-step explanation:

The standard form of the given equation is y = -1/3 x +4.

The given equation is y-2 = -1/3(x + 6)

What is the slope intercept form?

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

Here, the given equation can be rewritten as

y-2 = -1/3 x + 2

y = -1/3 x + 2+2

y = -1/3 x +4

Therefore, the standard form of the given equation is y = -1/3 x +4.

Store A sells 3 t-shirts for $25. Store B sells the same t-shirts: 5 for $40. Which store has the better deal?
Show your work supporting your answer.

Answers

Answer:

Store B

Step-by-step explanation:

To figure out which store has the better deal, we need to figure out the price per unit. We can do this by dividing the price by the number of the shirts. Store A sells their t-shirts for 8.33 or 8 1/3 dollars per shirt, while Store B sells their shirts for 8 dollars a shirt. 8 < 8 1/3, therefore Store B has the better deal.

Answer:

B.

Step-by-step explanation:

65% of 80 82% of 50 170% of 30

Answers

The correct answer is 82% of 50 (41) / 170% of 30 (51) /65% of 80 (52)

Explanation:

The first step to know whether a value is greater than another is to find the value each percentage represents depending on the total. This process is shown below.

1. 65% of 80- This implies 80 is 100% and 85% needs to be found. Use the following formula:

80 / 100 = 0.8 x 65 = 52 or the total number divided by 100 and multiplied by the percentage you want to know

2. 82% of 50 - Repeat the same process

50 / 100 = 0.5 x 82 = 41

3. 170% of 30

30 / 100 = 0.3 x 170 = 51

4. Finally organize the values

82% of 50 (41)

170% of 30 (51)

65% of 80 (52)

Based on the information given about the percentages ,the ordering will be 82% of 50, 170% of 30, and 65% of 80.

Percentages.

It should be noted that 82% of 50 will be:

= 82% × 50

= 41

170% of 30 will be:

= 1.7 × 30

= 51

65% of 80 will be:

= 65% × 80

= 0.65 × 80

= 52

Find the measure of angle 1​

Answers

Answer:

∠1 = 116

Step-by-step explanation:

Find the inner angle first, the inner angle will be represented with x, also a triangle is 180 degrees, so:

57 + 59 + x = 180

116 + x = 180

subtract 116 from both sides

x = 64

So now u have the inner angle, and a straight line is also 180 degrees, so:

64 + ∠1 = 180

subtract 64 from both sides

∠1 = 116

The answer is 116
