Answer:

A. The ratios of the sine of the angle to the opposite side are the same.

Step-by-step explanation:

The law of sines is ...

sin(A)/a = sin(B)/b = sin(C)/c

Answer:

Option A is correct that is the ratio of the sine of an angle to the length of the opposite side is the same for all part of the triangle.

Step-by-step explanation:

Given:

Three angles of the triangles = ∠A ,  ∠B and ∠C

Three Sides of the triangle = a , b , c

We need to find statement which states the Law of Sines.

We know that Law of Sines is given by,

[tex]\frac{a}{sin\,A}=\frac{b}{sin\,B}=\frac{c}{sin\,C}[/tex]

or

[tex]\frac{sin\,A}{a}=\frac{sin\,B}{b}=\frac{sin\,C}{c}[/tex]

Therefore, Option A is correct that is the ratio of the sine of an angle to the length of the opposite side is the same for all part of the triangle.

The purple area is the sum of the circle sector and the triangle:

[tex]A = A_s+A_t[/tex]

Let's compute them one at the time:

The sector is identified by an angle of 260°, because it is the remainder of a 100° angle.

We can build this simple proportion

[tex]\text{total area}\div\text{total angle}=\text{sector area}\div\text{sector angle}[/tex]

The area of the circle is [tex]\pi r^2[/tex], so we have

[tex]\pi 8.35^2\div 360= A_s\div 260[/tex]

Solving for the sector area, we have

[tex]A_s = \dfrac{\pi\cdot8.35^2\cdot260}{360} = \dfrac{8.35^2\cdot 13\pi}{18}[/tex]

The triangle is an isosceles triangle, because two of the sides are radii. This means that the height is also a bisector, so we can cut the triangle in two 90-50-40 triangles.

Using the law of sines, we can deduce that the height is

[tex]8.35\sin(40)[/tex]

And half the base is

[tex]8.35\sin(50)[/tex]

So, the area of the triangle is

[tex]A_t = 8.35^2\sin(40)\sin(50)[/tex]

So, the purple area is

[tex]A = A_s+A_t =\\\dfrac{8.35^2\cdot 13\pi}{18}+8.35^2\sin(40)\sin(50) = 8.35^2\left(\dfrac{13}{18}\pi+\sin(40)\sin(50)\right)\approx 192.5[/tex]

Answer:

[tex]x^{2/3}[/tex]

Step-by-step explanation:

When you have a power then a root like that, you have to divide the power by the root.

So, in this case, you have q square (x²) and a cubic root (³√).

So, you take your square (2) and divide it by the cube (3), to get a new power of 2/3.

Let's verify it with x = 2

[tex]\sqrt[3]{2^{2} } = \sqrt[3]{4} = 1.59\\\\\\2^{2/3} = 1.59[/tex]

So, both expressions equal the same thing, it means they're equivalent.

A function is a relation where each input is related to exactly one output. In mapping diagrams, if an 'x' value is associated with multiple 'y' values, the relation is not a function. Make sure to check the mapping to determine this.

In mathematics, specifically in the area of functions and relations, a function is a type of relation where each input (or 'x' value) is related to exactly one output (or 'y' value). If a relation has an 'x' value that is associated with more than one 'y' value, we say that this relation is not a function. When examining mapping diagrams, you can tell if it's a function or not by checking this rule.

For example, if you have a mapping diagram where the number 1 (the 'x' value) is mapped to both 2 and 3 (the 'y' values), this would not be a function because one input is associated with more than one output. On the other hand, if you have a mapping where every 'x' value is mapped to one 'y' value, such as 1 to 2, 2 to 3 and 3 to 4, this is a function.

Answer:

  22.6°

Step-by-step explanation:

Since all three sides of the right triangle are given, you can use any of the trig ratios to find the angle. I choose to use the tangent.

  tan(A) = BC/AC = 5/12

Then the inverse trig function tells you ...

  A = arctan(5/12) = 22.6°

Check the picture below.

make sure your calculator is in Degree mode.

Answer:

6.4 m

Step-by-step explanation:

We have 2 expressions here.  The first one is the fact that r = y.  That's one of 2 equations.  The second one involves whats' left after cutting off certain lengths of each color string.  We cut 2.5 m from red, we cut 3.8 m from yellow.  We know that what's left of red is 1.5 times the length of what's left of yellow.  What's left of red is r - 2.5; what's left of yellow is y - 3.8.  We know that r = 1.5y, so filling that in with our corresponding expressions gives us

r - 2.5 = 1.5(y - 3.8)

Distribute to get

r - 25 = 1.5y - 3.2

Now from the first expression, r = y, so fill in y for r to get an equation in one variable:

y - 2.5 = 1.5y - 3.2

Combine like terms:

-.5y = -3.2 and divide to get

y = 6.4

Check it to make sure it works.  What's left of red should be 1.5 times the length of what's left of yellow and y = 6.4:

What's left of red: 6.4 - 2.5 = 3.9

What's left of yellow: 6.4 - 3.8 = 2.6

1.5 x 2.6 = 3.9, just like it should!

Final answer:

The domain of f(x) = (1/6)x + 2 is all real numbers and the range is y > 2.

Explanation:

The domain of the function f(x) = (1/6)x + 2 is {x | x is a real number} because there are no restrictions on the input values. The range of the function is {y | y > 2} because any value of x will give a y-value greater than 2. To find the range, you can consider that the slope of the function is positive, meaning that as x increases, y will also increase, but it will never go below 2.

Answer:

x= 36.2

Step-by-step explanation:

Because that's a right triangle and the reference angle and adjacent side measures are given to us, we can use the trig ratio for cosine.  Cosine relates the side adjacent to (next to...NOT ever the hypotenuse!) the angle to the hypotenuse.  Therefore, our equation will look like this:

[tex]cos(28)=\frac{32}{x}[/tex]

Solving for x we have

[tex]x=\frac{32}{cos(28)}[/tex]

Perform that operation on your calculator in degree mode and you'll get that the length of the hypotenuse is 36.2.  If for some reason, your math gave you the length of the hypotenuse and it was shorter than one of the other sides, you did something wrong.  The hypotenuse will ALWAYS be the longest side in a right triangle.

Answer:

[tex]5.x=5x\\x^{2} =4, x=2\\x=2[/tex]

Step-by-step explanation:

hope its right

Answer:

Step-by-step explanation:

Here y = -x^2 + 36.

We can choose x values pretty much at random and then calculate the associated y values:

x    y = -x^2 + 36

----  --------------------

0                      36

2                 -2^2 + 36 =  32

-2                  -4 + 36 = 32

3                  -9 + 36 = 27

You did not share the equation of the slanted line.  Let's assume that the equation of this line is y = mx + b.  The first two points in the table above are (0, 36) and (2, 32).  We could find the equation of this line as follows:

Slope:  as we move from (0, 36) to (2, 32), x increases by 2 and y decreases by 4.  Thus, the slope is m = rise / run = -4/2, or -2.  Using info from the point (0, 36), we find the y-intercept of this straight line:

y = mx + b becomes 36 = m(0) + b, so b = 36, and the line is y = -2x + 36.

We need to find the points of intersection of y = -2x + 36 and y = -x^2 + 36.  We can equate these equations to eliminate y:  -2x + 36 = -x^2 + 36, or

-2x = -x^2.  Equivalently, 2x - x^2 = 0, or (x)(2 - x) = 0.  Then x = 0 and x = 2.

This says that the line and the parabola intersect in at least two places:

(0, 36) and (2, 32).

Answer:

x = -0.04166666667

Step-by-step explanation:

2x + 8 * 96 = 0

2x * 96 = -8

x/2 * 96 = -8/2

x * 96 = -4

x = -4/96

x = -0.04166666667

Answer:

198

Explanation:

The way to solve this equation is by using the "X=96" from moving it to the x in the equation witch makes it "2(96) + 6" When the variable is after the letter like 2x it always means multiplying. So when you multiply 2(96) together you get 192, then you would add 6+192 which would equal 198. I hope I helped! :D

Convert to an improper fraction

[tex](1\frac{1}{2})=3/2[/tex]

substitute

[tex](1\frac{1}{2})/2=(3/4)=0.75\ \frac{cm}{ft}[/tex]

The area is equal to

The area of the scale drawing of Charlene's swimming pool is [tex]\( 67.5} \)[/tex] square feet.

To find the area of the scale drawing of Charlene's swimming pool, we need to understand the scale given and how it applies to the dimensions and area.

Given:

Actual area of the swimming pool: [tex]\( 120 \) ft\(^2\)[/tex]

Scale of the drawing: [tex]\( 1 \frac{1}{2} \) centimeters = 2 feet[/tex]

First, convert the scale to centimeters:

[tex]\[ 1 \frac{1}{2} \text{ centimeters} = 1.5 \text{ centimeters} \][/tex]

Now, determine the scale factor for the dimensions:

[tex]\[ \text{Scale factor} = \frac{1.5 \text{ cm}}{2 \text{ ft}} \][/tex]

To find the area of the scale drawing, we need to square the scale factor, because area is two-dimensional:

[tex]\[ \text{Area scale factor} = \left(\frac{1.5}{2}\right)^2 \][/tex]

[tex]\[ \text{Area scale factor} = \left(0.75\right)^2 \][/tex]

[tex]\[ \text{Area scale factor} = 0.5625 \][/tex]

Now, calculate the area of the scale drawing:

[tex]\[ \text{Area of scale drawing} = 0.5625 \times 120 \text{ ft}^2 \][/tex]

[tex]\[ \text{Area of scale drawing} = 67.5 \text{ ft}^2 \][/tex]

Choice D), since Katie went way over the decimals, and Amaya went slightly under to the closest number

Answer:

Amaya's estimate is the closer one.

D. Katie’s estimate will be greater than the actual product, and Amaya’s estimate will be less than the actual product

Step-by-step explanation:

The original expression is 89.1 x 9.3. Katie changed the 89.1 to 99 (difference of 9.9) and the 9.3 to 10 (difference of 0.7). On the other hand, Amaya changed the 89.1 to 89 (0.1 difference) and the 9.3 to 9 (0.3 difference).

Therefore the best comparison would be Amaya's estimate since her numbers are closer to the original expression.

Katie's estimate will be greater than the actual product because she rounded up the numbers and Amaya's estimate will be less than the actual product because she rounded down the numbers.

Answer:

-7+6i

Step-by-step explanation:

On the Cartesian x-y plane, a point is located by giving the ordered pair of its coordinates. A point in this position on the x-y plane would have coordinates (-7, 6). That is, it is located 7 units to the left of the vertical axis, and 6 units above the horizontal axis.

The complex plane is similar in many ways, but each point represents a single number (not a pair of numbers). That single number has two parts: a real part and an imaginary part. The real part is measured by the real axis, a horizontal axis that looks very much like the x-axis of a Cartesian plane. The imaginary part is measured against the imaginary axis, a vertical axis that looks very much like the y-axis of a Cartesian plane.

Just as an ordered pair locates a point on the Cartesian plane, a complex number with a real part and an imaginary part locates a point on the complex plane. The imaginary part is identified by the "i" multiplier. (In some fields of study, notably Electrical Engineering, "j" is used instead of "i", because "i" has a different meaning.)

Here, your point is 7 units left of the imaginary axis, so has a real part of -7. It is 6 units above the real axis, so has an imaginary part of 6. When both parts are written together, the number is written -7+6i.

Comparing this form to a+bi, we find a=-7, b=6.
