Answer:

C) 0.5

Step-by-step explanation:

Since DE is parallel to AB, angle FDE = ABF and  DEF = angle FAB

In fact, both triangles (ABF and DEF) are similar to each other because their interior angles are identical.

So, if sin(A) = 0.5, sin(E) = 0.5 too.

Step-by-step explanation:

Daniel and his friends go to an amusement park to get on the fireball that costs $ 5 and the bumper cars cost $ 1 less. If Daniel climbs a total of 11 times and spends $ 50, how many times did he go up to each attraction?

costo de la bola de fuego: $5

costo de los coches de choque: 5 - 2 = $4

número de veces que montó bola de fuego = b

número de veces que montó de choque: m

b + m = 11 --> b = 11 - m

5b + 4m = 50

5(11 - m) + 4m = 50

55 - 5m + 4m = 50

m = 5

b + 5 = 11

b = 6

For this case we must simplify the following expression:

[tex]\sqrt [3] {\frac {12x ^ 2} {16y}}[/tex]

We rewrite the expression as:

[tex]\sqrt[3]{\frac{4(3x^2)}{4(4y)}}=\\\sqrt[3]{\frac{4(3x^2)}{4(4y)}}=\\\frac{\sqrt[3]{3x^2}}{\sqrt[3]{4y}}=[/tex]

We multiply the numerator and denominator by:

[tex](\sqrt[3]{4y})^2:\\\frac{\sqrt[3]{3x^2}*(\sqrt[3]{4y})^2}{\sqrt[3]{4y}*(\sqrt[3]{4y})^2}=[/tex]

We use the rule of power[tex]a ^ n * a ^ m = a ^ {n + m}[/tex] in the denominator:

[tex]\frac{\sqrt[3]{3x^2}*(\sqrt[3]{4y})^2}{(\sqrt[3]{4y})^3}=\\\frac{\sqrt[3]{3x^2}*(\sqrt[3]{4y})^2}{4y}=[/tex]

Move the exponent within the radical:

[tex]\frac{\sqrt[3]{3x^2}*(\sqrt[3]{16y^2}}{4y}=\\\frac{\sqrt[3]{3x^2}*(\sqrt[3]{2^3*(2y^2)}}{4y}=[/tex]

Answer:

[tex]r=4\csc \theta \cot\theta[/tex]

Step-by-step explanation:

The given parametric equations are;

[tex]x=t^2[/tex]

[tex]y=2t[/tex]

We make t the subject in the second equation to get:

[tex]t=\frac{y}{2}[/tex]

We substitute into the first equation to get:

[tex]x=(\frac{y}{2})^2[/tex]

We use the relation:

[tex]x=r\cos \theta[/tex] and [tex]y=r\sin \theta[/tex]

[tex]r\cos \theta=(\frac{r\sin \theta}{2})^2[/tex]

[tex]r\cos \theta=\frac{r^2\sin^2 \theta}{4}[/tex]

[tex]r=4\csc \theta \cot\theta[/tex]

An equation is formed of two equal expressions. The polar form of parametric equations x=t² and y=2t is r = 4cosecθ cotθ.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The following parametric equation x=t² and y=2t in the form of a polar equation can be written as,

y=2t

t = y/2

Substituting the value of y from the second equation in the first,

x = (y/2)²

Using the basic relation we can write, the value of x and y as,

x = r cosθ

y = r sinθ

substitute the value of x and y,

r cosθ = [(r sinθ)/2]

r sinθ = (r²sin²θ)/4

r = 4cosecθ cotθ

Hence, the polar form of parametric equations x=t² and y=2t is r = 4cosecθ cotθ.

Answer:

[tex]\frac{\sqrt[3]{5} }{3x}[/tex]

Step-by-step explanation:

Ok, let's do this step by step....

[tex]\sqrt[3]{\frac{10x^{5} }{54x^{8} } }[/tex]

Let's first simplify the x's:

[tex]\sqrt[3]{\frac{10}{54x^{3} } }[/tex]

Then we breakdown the 54 as 2 * 27 then simplify with the 10 above.

[tex]\sqrt[3]{\frac{10}{2 * 27x^{3} } } = \sqrt[3]{\frac{5}{27x^{3} } }[/tex]

Now, we can rewrite this as the following and solve the bottom part:

[tex]\frac{\sqrt[3]{5} }{\sqrt[3]{27x^{3} } } = \frac{\sqrt[3]{5} }{3 \sqrt[3]{x^{3} } } = \frac{\sqrt[3]{5} }{3x}[/tex]

Answer:

$560.29

Step-by-step explanation:

To find the total price, first, find out how much of $519.99 is 7.75%

To do this convert %7.75 into a decimal [divide by 100]

7.75% = 0.0775

Now multiply 0.0775 by $519.99

519.99 x 0.0775 = 40.299225

Since 40.299225 is an amount of money, round it to the nearest hundreth in cents.

40.299225 = 40.30

Now add the sales tax and original price.

$40.30 + $519.99 = 560.29

So, the cost of the bicycle after sales tax is $560.29

The ratio of baseballs to the total number of balls in the storage room is 1:5. For every one baseball, there are five balls of any type.

We are looking for the ratio of baseballs to total balls. We find the total by adding the number of each type of balls: 10 (baseballs) + 4 (basketballs) + 12 (softballs) + 4 (soccer balls) + 20 (tennis balls) = 50 balls in total.

Now that we know the total, we can find the ratio of baseballs to the total amount of balls. There are 10 baseballs from a total of 50 balls. Thus, the ratio would be 10:50. Simplified, this ratio would be 1:5. This means for every one baseball, there are five balls of any type.

Step-by-step explanation:

The graph will be a straight line that starts at the origin and rises diagonally to the right with a slope of 2. The correct graph id graph 2

Since each light panel holds two light bulbs, the number of light bulbs, y, is directly proportional to the number of light panels, x. This means that as the number of light panels increases, the number of light bulbs will also increase in a linear manner.

The relationship can be represented by the equation:

y = 2x

Where y represents the number of light bulbs and x represents the number of light panels.

The graph representing the relationship between the number of light panels, x, and the number of light bulbs, y, will be a straight line.

In this case, the line will have a positive slope of 2 since each light panel holds two light bulbs. This means that for every increase of one unit in the number of light panels, the number of light bulbs will increase by two units.

The graph will pass through the origin (0, 0) since when there are no light panels (x = 0), there will be no light bulbs (y = 0).

As x increases, y will also increase in a linear manner. The line will extend indefinitely in the positive direction in both the x-axis and y-axis, indicating that the relationship continues without any upper limit.

Visually, the graph will be a straight line that starts at the origin and rises diagonally to the right with a slope of 2.

The domain of the function is all the real numbers except the number 13:

Domain: (-∞,13)∪(13,∞)

This is a composite function problem. To solve it, we need to remember how to composite a function. Composing a function consists of evaluating a function into another function.

Composite function is equal to:

[tex]f(g(x))=(f\circ} g)(x)[/tex]

So, the given functions are:

[tex]f(x)=x+7\\\\g(x)=\frac{1}{x-13}[/tex]

Then, composing the functions, we have:

[tex]f(g(x))=\frac{1}{x-13}+7\\[/tex]

Therefore, we must remember that the domain are all those possible inputs where the function can exists, most of the functions can exists along the real numbers with no rectrictions, however, for this case, there is a restriction that must be applied to the resultant composite function.

If we evaluate "x" equal to 13, the denominator will tend to 0, and create an indetermination since there is no result in the real numbers for a real number divided by 0.

So, the domain of the function is all the real numbers except the number 13:

Domain: (-∞,13)∪(13,∞)

The product of 2x + y and 5x – y + 3 is 10x^2+ 3xy + 6x - y^2 + 3y

Step-by-step explanation:

The product of the two expressions can be expressed mathematically as;

(2x +y) (5x -y +3)

To obtain the product of these expressions, we simply expand the brackets as follows;

2x(5x -y +3) + y(5x -y +3)

= 10x^2 - 2xy + 6x + 5xy - y^2 + 3y

= 10x^2- 2xy + 5xy + 6x - y^2 + 3y

= 10x^2+ 3xy + 6x - y^2 + 3y

The product of 2x + y and 5x – y + 3 is thus 10x^2+ 3xy + 6x - y^2 + 3y

Step-by-step explanation:

I take it that the base of the log is 4.

So the question can be written as

log_4 [(x+2)/(x + 3)] = -1

If you take the antilog of this, you get

(x + 2)/(x+3) = 4^-1 = 1/4

Now Cross Multiply

4*(x + 2) = 1*(x + 3)               Remove  the brackets on both sides

4x + 8 = x + 3                       subtract x from both sides.

4x - x + 8 = x - x + 3             Combine

3x + 8 = 3                             Subtract 8 from both sides

3x = 3 - 8                              Combine

3x = - 5                                 Divide by 3

x = - 5/3

Answer:

16682.7 cm³

Step-by-step explanation:

The total volume is the volume of the cone plus half the volume of a sphere:

V = ⅓ π r² h + ½ (4/3 π r³)

V = ⅓ π r² h + ⅔ π r³

V = ⅓ π r² (h + 2r)

Given that r = 4.15 cm and h = 10.2 cm:

V = ⅓ π (4.15)² (10.2 + 2×4.15)

V ≈ 333.65

The volume needed for 50 cones is therefore:

50V ≈ 16682.7 cm³
