Determine if the graph of r = 4cos 5θ is symmetric about the x-axis, the y-axis, or the origin.

Answers

Answer 1

Answer:

y-axis

Step-by-step explanation:

The function graph is symmetric about

- the y-axis when it is an even function

- the origin when it is an odd function.

A symmetrical graph about the x-axis is not a function graph.

f(x) is an even if and only if f(-x) = f(x).

f(x) is an odd if and only if f(-x) = -f(x).

We have the function r(θ) = 4cos(5θ)

(olny symmetry about the y-axis or about the origin)

Check r(-θ):

r(-θ) = 4cos(5(-θ)) = 4cos(-5θ) = 4cos(5θ)

used cos(-x) = cos x

We have r(-θ) = r(θ). Therefore the graph of r(θ) is symmetric about the y-axis.

Answer 2

Answer:

x-axis

Step-by-step explanation:

if r%28theta%29+=+r%28-theta%29.

Since 4cos%285%2Atheta%29+=+4cos%28-5%2Atheta%29, the graph is symmetric wrt the x-axis.

The graph is symmetric wrt the y-axis if r%28theta%29+=+r%28pi-theta%29.

 

Since 4cos%285%2Atheta%29+%3C%3E+4cos%285%2A%28pi+-+theta%29%29+=+-4cos%285%2Atheta%29+, the graph is not symmetric wrt the y-axis.

The graph is symmetric wrt the y-axis if r%28theta%29+=+r%28pi%2Btheta%29.

Since 4cos%285%2Atheta%29+%3C%3E+4cos%285%2A%28pi+%2B+theta%29%29+=+-4cos%285%2Atheta%29+, the graph is not symmetric wrt the origin.

When a number is divided by -3, the result is 12 more than the number what is the number?

Answers

Final answer:

To find the number that, when divided by -3, the result is 12 more than the number, we set up an equation and solve it to get the answer, which is -9.

Explanation:

When a number is divided by -3, and the result is 12 more than the number itself, we can set up the following equation to find the number: number / -3 = number + 12. Following division and multiplication rules for signs, and executing proper algebraic manipulations, we can solve this equation.

First, we multiply both sides by -3 to get rid of the fraction:
-3 * (number / -3) = -3 * (number + 12),
which simplifies to:
number = -3(number) - 36.
Next, we add 3(number) to both sides to get:
4(number) = -36.
Finally, we divide both sides by 4 to isolate the 'number':
number = -36 / 4
number = -9.

Therefore, the number in question is -9.

Write the equation, in slope-intercept form, of the line passing through the origin and the point $(-4,3)$.

Answers

If the equation is passing trough the origin, it will be passing trough the point (0,0). We now for our problem that the equations is also passing trough the point (-4,3). So, our line is passing trough the points (0,0) and (-4,3). To write the equation in slope-intercept form, first, we need to find its slope [tex]m[/tex]. To do that we are going to use the slope formula: [tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}} [/tex].
From our two points we can infer that [tex]x_{1}=0[/tex], [tex]y_{1}=0[/tex], [tex]x_{2}=-4[/tex], [tex]y_{2}=3[/tex]. Lets replace those values in the slope formula:
[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}} [/tex]
[tex]m= \frac{3-0}{-4-0} [/tex]
[tex]m= \frac{3}{-4} [/tex]
[tex]m=- \frac{3}{4} [/tex]

Now that we have our slope, we can use the slope-intercept formula:
[tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y-0=- \frac{3}{4} (x-0)[/tex]
[tex]y=- \frac{3}{4} x[/tex]

We can conclude that the equation of the line passing trough the points (0,0) and (-4,3) is [tex]y=- \frac{3}{4} x[/tex].

The amount of cups of flour needed to make 1/2 of the original recipe is 7/8 cups.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Recipe:

Amount of flour for muffins = [tex]1\frac{1}{2}[/tex] = 3/2 cups

Amount of flour for toppings = [tex]\frac{1}{4}[/tex] = 1/4 cups

The total amount of flour:

= 3/2 + 1/4

= (12 + 2) / 8

= 14 / 8

= 7/4 cups

We see that the total amount of flour needed to make one Cara muffin recipe is 7/4 cup of flour.

To make 1/2 of the original recipe.

The amount of flour needed:

1 recipe = 7/4 cups

Divide both sides by 2.

1/2 recipe = 1/2 x 7/4 cups

1/2 recipe = 7/8 cups

Thus,

The amount of cups of flour needed to make 1/2 of the original recipe is 7/8 cups.

In 2004, the world's largest carousel was located at the House on the Rock, in Spring Green, Wisconsin. Suppose that the center of the carousel is at the origin and that one of the animals on the circumference of the carousel has coordinates (24, 32). If one unit of the coordinate plane equals 1 foot, what is the diameter of the carousel

Answers

1. You have that the Standard form for the equation of a circle when its center is at the origin, is:

 x²+y²=r²

 2. You must calculate the radius. Then:

 r=√(x²+y²)

 x=24
 y=32

 3. When you substitute the values of "x" and "y" into the equation r=√(x²+y²), you obtain:

 r=√(x²+y²)
 r=√(24²+32²)
 r=√(576+1024)
 r=√1600
 r=40 feet

 4. Therefore, the diameter (D) of the circle, is:

 D=2r
 D=2(40 feet)
 D=80 feet

If ED = 10 and DB = 3x-8, what is the length of EB

2. 22
3. 10
4. 20

Answers

Based on the picture, we know that ED is equal to DB. Therefore:

2 times ED=EB
2(10)=20

EB is 20
Answer:
EB = 20 units

Explanation:
This question can be solved using two methods:
Method #1:
From the image, we can note that D is the midpoint of EB, therefore, ED = DB
This means that:
EB = 2*10 = 20 units

Method #2:
From the image, we know that ED = DB
We are given that ED = 10 units
Therefore:
DB = 3x - 8 = 10
3x = 18
x = 6
DB = 3(6) - 8 = 18 - 8 = 10 units
EB = EB + DB = 10 + 10 = 20 units

The difference of two numbers is 44 1/2 . If the smaller of the two numbers increases 7 times then the difference will be 10 3/14 . Find the numbers.

The numbers are: ___ ,___ or ____,___

Answers

Answer: The smaller number is 9 and 5/42. The larger number is 53 and 13/21.

To find these answer you have to write the following two equations.

x - y = 44 and 1/2
7y - x = 10 and 3/14

Then, you can use the substitution method to solve them. Change the first equation to: x = 44 + y. Substitute that into the second equation and solve for y. Once you have that, plug it back into the first equation and solve for x.

The smaller number is 11 and the larger number is [tex]55 \frac{1}{2}[/tex].

Let's denote the two numbers as x and y, where x is the smaller number. We're given that [tex]y - x = 44 \frac{1}{2}[/tex] and [tex]7x - y = 10 \frac{3}{14}[/tex].

To solve this system of equations, we can use substitution or elimination. Let's use elimination:

1. Multiply the second equation by 2 to clear fractions: [tex]14x - 2y = 20 \frac{6}{14}[/tex].

2. Add the modified second equation to the first equation:

[tex](y - x) + (14x - 2y) = 44 \frac{1}{2} + 20 \frac{6}{14}[/tex]

[tex]13x - y = 64 \frac{11}{14}[/tex]

Now, we have a simpler equation: [tex]13x - y = 64 \frac{11}{14}[/tex].

3. Add this equation to the original second equation to find x:

[tex]7x - y + 13x - y = 10 \frac{3}{14} + 64 \frac{11}{14}[/tex]

[tex]20x - 2y = 75[/tex]

4. Now, we can solve this equation along with the first equation to find x and y.

After solving, we get x = 11 and [tex]y = 55 \frac{1}{2}[/tex].

The smaller number is 11 and the larger number is [tex]55 \frac{1}{2}[/tex].

Thus, the numbers are [tex]{11 \text{ and } 55 \frac{1}{2}}[/tex].

Each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 feet. If there are four blades on the windmill, what is the total area of the blades 1.56 ft2 2.14 ft2 3.28 ft2 or 4.96 ft2 im unsure of this one but im going with 2.,

Answers

The area of a blade with rectangular shape = 1/2 * b * h where b is the base and h, the height. Here b = 7 and height = 4 So the area of the blade = 1/2 * 7 * 4 = 14ft^2 If the are four blades the total area is the summation of individual blade. So area = 14 + 14 + 14 + 14 = 56ft^2. Hence none of the option satisfies the answer.

A little help pwease :o ? A group of 45 people attended a ball game. There were twice as many children as adults in the group.

Answers

45= 2(a) + a
45= 2a + a
45= 3a

30. Since there are twice as many children as adults, let's say the number of adults is x. That means the amount of children is 2x. You know that in total there are 45 people. This means that the number of adults plus the number of children is 45. So we can set up x + 2x = 45. We can solve for x. 3x = 45 so x = 15. Remember, as we stated before, x is the number of adults. 2x is the number of children. Since x = 15, 2x = 30 so there are 30 children in the group.

To find the total area of this figure, it would be easiest to find the area of the left part (rectangle) and then find the area of the right part (triangle), and then add the two area values together.

First, we will find the area of the rectangle, using the formula A = lw, where l is the length of the rectangle and w is the width of the rectangle.
The length of the rectangle is 13 cm and the width is 9 cm. If we substitute in these values into our equation, we get:
A = (13cm)(9cm)
A= 117 cm^2

Next, let’s find the area of the triangle, using the formula A=(1/2)bh, where b is the base of the triangle and h is the height.
The base of the triangle is 11 cm and the height of the triangle is 5 cm (found by subtracting 13-8 as seen in the figure). If we substitute in these values and simplify, we get:
A=1/2(11cm)(5cm)
A=1/2(55cm^2)
A=27.5 cm^2.

When we add together the area of the rectangle with the area of the triangle, we will get the total area of the figure.

117 cm^2 + 27.5 cm^2 = 144.5 cm^2
Your answer is 144.5 cm^2 or the first option.

Step-by-step explanation:

We have been given an expression and we are asked to find factor out our given expression.

[tex]4x^3+2x^2+2x[/tex]

To factor our given expression we need to factor out the greatest common factor of each term of our given expression.

We can rewrite our given expression as:      

[tex](2\cdot 2\cdot x\cdot x\cdot x)+(2x\cdot x)+2x[/tex]

We can see that the greatest common factor of our given expression is 2x.

Upon factoring out 2x from our given expression we will get,

[tex]2x(2\cdot x\cdot x+x+1)[/tex]

[tex]2x(2x^2+x+1)[/tex]

Therefore, the factored form of our given expression is [tex]2x(2x^2+x+1)[/tex] .
