There are 16 teams in the state basketball tournament. If each team has an equal chance of winning, what are the chances that the places will go as follows
1st place- West Hordon HS
2nd place- Riverton
3rd place- Bingham
4th place- Copper Hills
Answer:
25%
Step-by-step explanation:
16/4=4 and that would be like 25/100 because 25 times 4 is 100 so it is 25%
3x^2 - 6 = 2x wat is discriminant of the quadratic equation
Answer:
The discriminant is 76
Step-by-step explanation:
The equation needs to be in the form
ax^2 +bx +c =0
3x^2 - 6 = 2x
Subtract 2x from each side
3x^2 -2x - 6 = 0
The discriminant is
b^2 - 4ac
a = 3 b = -2 c = -6
(-2)^2 -4(3) (-6)
4 + 72

What is the rectangular form of the polar equation?
r−rcosθ=6
Step-by-step explanation:
r − r cos θ = 6
r = r cos θ + 6
r² = (r cos θ + 6)²
x² + y² = (x + 6)²
x² + y² = x² + 12x + 36
y² = 12x + 36
The rectangular form of the polar equation is x² + y² = 2x + y - 2.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
To convert a polar equation to rectangular form, you can use the following relationships between polar and rectangular coordinates:
x = r x cos(theta)
y = r x sin(theta)
where r is the distance from the origin to the point in polar coordinates, and theta is the angle between the positive x-axis and the line connecting the origin and the point.
Now,
So, if you have a polar equation in the form of r = f(theta), you can substitute these expressions for x and y into the equation to obtain a rectangular equation in terms of x and y.
The resulting equation will typically be a function of x and y, rather than just one variable as in the polar form.
For example,
If you have the polar equation r = 2 + sin(Ф), you can substitute x = rcos(Ф) and y = rsin(Ф) to get:
x = (2 + sin(Ф)) x cos(Ф)
y = (2 + sin(Ф)) x sin(Ф)
Simplifying these expressions using trigonometric identities, you can get the rectangular form of the polar equation:
x² + y² = 2x + y - 2
Thus,
The rectangular form of the polar equation is x² + y² = 2x + y - 2.

In the diagram below of circle O, chords ab and cd intersect at E.
If measure of arc AC = 72° and measure of arc AEC = 58°, how many degrees are in measure of arc DB?
Answer:
Correct option: 3
Step-by-step explanation:
When we have a crossing of two chords in a circle, there is a property that relates the angles in the intersection point and the arcs defined in the circle. From this property, we have that:
mAEC = (1/2) * (mAC + mBD)
Using the values of mAEC = 58° and mAC = 72°, we have that:
58 = (1/2) * (72 + mBD)
116 = 72 + mBD
mBD = 116 - 72
mBD = 44°
Correct option: 3

Charlotte is redecorating the master bedroom in her house. She has already purchased a new bedroom set and also plans to paint the room and put in new flooring. The new bedroom set she purchased includes a queen-sized bed, one nightstand, and a dresser. The bed cost $558.49, and the cost of the dresser represented 1/4 of the total amount Charlotte spent on furniture.
For the flooring, Charlotte has decided to put new carpet in the bedroom. She has calculated that the carpet itself will cost $427.35, and the labor to install the carpet will cost $212.52. There is also a $75 fee covering the cost of other flooring supplies, tools, and materials.
1. What percent of the flooring bill will go towards the cost of labor? Round your answer to the nearest percent.
2. If Charlotte spent 25% more on furniture than she will on flooring, how much did she spend on furniture to the nearest cent?
3. What percent of the total furniture cost did Charlotte spend on the nightstand? Round your answer to the nearest percent.

Step-by-step explanation:
a. Given that the carpet costs $427.35, the labor costs $212.52 and other flooring supplies costs $75.
#To get the percent of the flooring bill that will go towards the cost of labor:
Hence, labor costs 30% of the total flooring costs.
b.The total flooring costs is :
Given that she spends 25% more on furniture than on flooring, we multiply the flooring cost by 125% to get the furniture costs:
Hence, she spends $893.59 on furniture.
c.To get what percentage of furniture cost was the night stand.
-Given the total furniture cost is $893.59:
Let x be the cost of the dresser and y the cost of the nightstand;

3x−4y=−24 Response : A. y=34x+6 B. y=−6x−34 C. y=6x−34 D. y=−34x+6
Answer:
y = 3/4 x +6
Step-by-step explanation:
3x−4y=−24
Solve for y
Subtract 3x from each side
3x-3x−4y=-3x−24
-4y = -3x-24
Divide each side by -4
-4y/-4 = -3x/-4 -24/-4
y = 3/4 x +6

Answer:
hey !
your answer is C
x=
x/2
Step-by-step explanation:
If the function f(x)=2x then the inverse function is f⁻¹(x) =x/2.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given function is f(x)=2x.
y=2x
Interchange the variables.
x=2y
Now solve for y
y=x/2
Replace y with f⁻¹(x) to show the final answer.
f⁻¹(x) =x/2
Hence, if the function f(x)=2x then the inverse function is f⁻¹(x) =x/2.

In the diagram below, square ABCD has side lengths of 6 inches. Arc AC has been drawn with center at point D. Which of the following is closest to the shaded area in square inches?
Answer:
7.73
Step-by-step explanation:
In the picture attached, the diagram is shown.
Area of square = side² = 6² = 36 in²
The non-shaded area is quarter the area of the circle's area with radius = side of the square. This area is: (1/4)*π*radius² = (1/4)*π*6² = 28.27 in²
Therefore, the shaded area is: Area of square - non-shaded area = 36 in² - 28.27 in² = 7.73 in²

Find the exact value of cos300°.
Answer:
ok it's simple
cos300° = 0.5 if you want a numerical value .....
Step-by-step explanation:
hopefully it will help youAnswer:
1/2
Explanation:
Exact value means put the calculator away and go to an x/y coordinate plane. Set the angle up in standard position with the initial ray on the positive x-axis and the terminal ray will move counterclockwise around until is sweeps out a 300 degree angle. That angle will be in the fourth quadrant, 60 degrees BELOW the x-axis you started on. But we are not using the negative value, which is measured clockwise. From the negative y axis that is the 270 degree line, we add 30 to that 270 and get the 300 degree angle we want. Angles are always measured from the terminal ray to whichever x-axis its closest to. From the terminal ray to the x-axis forms a 60 degree angle. That means that the reference angle is 60. The side across from a 60 degree angle in a 30-60-90 right triangle is square root of 3, but our side is in the negative y's so it is . Along the x axis is the side across from the 30 degree angle which is a +1. The hypotenuse is 2. These values are from the Pythagorean triple for a 30-60-90 right triangle and should be familiar at this point. The cos identity is the side adjacent to the reference angle over the hypotenuse so our exact value for cos 300 is 1/2.
Can 5, 2, 4 be the measures of the sides of a triangle?
Answer: Yes
Step-by-step explanation:
In order to form a triangle, the sum of two sides must be GREATER than the third side.
a + b > c & a + c > b & b + c > a
5 + 2 > 4 & 5 + 4 > 2 & 4 + 2 > 6
True True True
The sides 5, 2, 4 satisfy the rules for forming a triangle.
