15. If m arc BY = 40 degrees, what is m angle YAC? the figure is not drawn to scale.
Answers
If [tex]m\widehat{BY}=40^\circ[/tex], then the central angle [tex]\angle BOY[/tex] has the same measure, and by the inscribed angle theorem we have
[tex]m\angle BAY=\dfrac12m\angle BOY=20^\circ[/tex]
It's impossible to know what the measure of angle YAC is from this information alone, but assuming AC is tangent to the circle, then angles BAY and YAC are complementary, so that [tex]m\angle YAC=70^\circ[/tex].
The line AC is the tangent of the line, and the measure of the angle YAC is 70 degrees
How to determine the measure of YAC?The measure of the arc is given as:
Arc BY = 40 degrees
The measure of angle BAY is calculated using:
BAY = 0.5 * BY
This gives
BAY = 0.5 * 40
BAY = 20
The angle at a tangent is 90 degrees.
This means that:
BAY + YAC = 90
Substitute 20 for BAY
20 + YAC = 90
Subtract 20 from both sides
YAC = 70
Hence, the measure of the angle YAC is 70 degrees

During the trip, the Morales family drove on several different highways. Gabriela and Luis noticed that sometimes the mile markers were increasing, and other times the mile markers were decreasing.
On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277at 3:00. Since Mr. Morales was driving at a constant speed, their mile-marker location over time can be represented by a line where the time in hours is the independent variable and the mile marker is the dependent variable. The points (1,123) and (3,277) are two points on this line.
What is the value of the slope of this line?

Answers
Answer:
The slope of the line is 77
Explanation:
We know the speed is constant and that the mile-marker location over time can be represented by a line. This means that the equation is linear.
The slope can, therefore, be calculated as follows:
[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁ , y₁) and (x₂ , y₂) are two points on the line
We are given that the two points (1, 123) and (3, 277) are two points in the line
Substitute with them in the above equation to get the slope as follows:
[tex]slope = \frac{277-123}{3-2}=77[/tex]
Hope this helps :)
The slope of a line represents the rate of change between two variables. The value of the slope in this scenario is 77/2.
The slope of a line represents the rate of change between two variables. In this case, the slope can be calculated using the formula:
slope = (change in y) / (change in x).
Given the points (1,123) and (3,277), the slope can be calculated as follows:
slope = (277 - 123) / (3 - 1).
Therefore, the value of the slope of the line representing the Morales family's mile-marker locations over time is 77/2.

Find two additional polar representations of the point. Write each coordinate in simplest form with the angle in
Answers
Answer:
The other two other representation are (6 , -4π/3) and (-6 , -π/3)
Step-by-step explanation:
* Lets revise some important facts about the polar form of a point
- In polar coordinates there is an infinite number of coordinates for a
given point
- The point (r , θ) can be represented by any of the following coordinate
pairs (r , θ+2πn) , (-r , θ + [2n+1]π) , where n is any integer
* Now lets solve the problem
∵ A point has polar coordinates (6 , 2π/3)
- We can find many points as the same with this point
- The point (r , θ) can be represented by any of the following coordinate
pairs(r , θ + 2πn) and (-r , θ + (2n + 1)π), where n is any integer.
∵ The angle in [-2π , 2π]
∵ r = 6 and Ф = 2π/3
- Let n = -1
∴ (r , Ф + 2πn) = (6 , 2π/3 + 2π(-1)) = (6 , 2π/3 - 2π) = (6 , -4π/3)
* One point is (6 , -4π/3)
∴ (-r , θ + (2n + 1)π) = (-6 , 2π/3 + (2(-1) + 1)π) = (-6 , 2π/3 + (-2 + 1)π)
∴ (-r , θ + (2n + 1)π) = (-6 , 2π/3 + (-1)π) = (-6 , 2π/3 - π)
∴ (-r , θ + (2n + 1)π) = (-6 , -π/3)
* One point is (-6 , -π/3)
Final answer:
To find two additional polar representations of a point, you can add or subtract 2π radians (or 360° if using degrees) from the original angle, while keeping the radius the same.
Explanation:
A student has asked for two additional polar representations of a point. Polar coordinates specify the location of a point in a plane by a distance from the origin (r) and an angle (φ) with respect to the positive x-axis. To find additional representations, we can add 2π radians to the angle for each full rotation around the circle, keeping the same distance 'r'. For example, if a point has polar coordinates (r, φ), two other representations could be (r, φ + 2π) and (r, φ - 2π), or if in degrees, (r, φ + 360°) and (r, φ - 360°).
The general form of the equation of a circle is x2+y2−4x−8y−5=0.
What are the coordinates of the center of the circle?
Enter your answer in the boxes.
Answers
Answer:
centre = (2, 4)
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² - 4x - 8y - 5 = 0
Rearrange the x/y terms together and add 5 to both sides
x² - 4x + y² - 8y = 5
Use the method of completing the square on both the x/y terms
add ( half the coefficient of the x/y terms )² to both sides
x² + 2(- 2)x + 4 + y² + 2(- 4)y + 16 = 5 + 4 + 16
(x - 2)² + (y - 4)² = 25 ← in standard form
with centre (2, 4) and r = [tex]\sqrt{25}[/tex] = 5

Look at the picture.
ΔABC, ΔDBA and ΔDAC are the triangles 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.
Therefore
in ΔDAC:DC : AD : AC = 1 : √3 : 2
If AC = 10, then DC = 10 : 2 = 5 and AD = x = 5√3
in ΔDBA:AD : BD : AB = 1 : √3 : 2
If AD = 5√3, then AB = 2 · 5√3 = 10√3 and BD = y = 5√3 · √3 = 5 · 3 = 15

The answer is g(x)=(x-6)(2x-1).hope this helps please add brainlist
Answer:
[tex]\boxed{g(x) = (x - 6)(2x - 1)}[/tex]
Step-by-step explanation:
An x-intercept is the value of x when g(x) = 0. So, for each function, we must set g(x) = 0 and solve for x.
(a) g(x) = 2(x + 1)(x + 6) = 0
x + 1 = 0 x + 6 = 0
x = -1 x = -6
Wrong.
(b) g(x) = (x - 6)(2x - 1)
x - 6 = 0 2x – 1 = 0
x = 6 2x = 1
x = ½
Right.
(c) g(x) = 2(x - 2)(x - 6)
x - 2 = 0 x - 6 = 0
x = 2 x = 6
Wrong.
(d) g(x) = (x + 6)(x + 2)
x + 6 = 0 x +2 = 0
x = -6 x = -2
Wrong.
The only function that has x-intercepts at (½, 0) and (6, 0) is

Step-by-step explanation:
* To factor a trinomial in the form ax² ± bx ± c:
- Look at the c term
# If the c term is positive
∵ c = r × s ⇒ r and s are the factors of c
∴ r and s will have the same sign (sign of b)
∵ a = h × k ⇒ h , k are the factors of a
∴ rk + hs = b
∴ (hx + r)(kx + s) ⇒ if b +ve OR (hx - r)(kx - s) ⇒ if b -ve
# If the c term is negative
∵ c = r × s ⇒ r and s are the factors of c
∴ r and s will not have the same sign
∵ a = h × k ⇒ h and k are the factors of a
∴ rk - hs = b OR hs - rk = b
(hx + r)(kx - s) OR (hx - r)(kx + s)
* Now lets solve the problem
∵ 2a² + 5a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 1 × 3 then r = 1 , s = 3
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 1
∵ sh = 6
∴ sh - rk = 5 ⇒ same value of b
∵ (hx - r)(kx + s)
∴ 2a² + 5a - 3 = (2a - 1)(a + 3)
∵ 2a² - a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 3 × 1 then r = 3 , s = 1
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 3
∵ sh = 2
∴ sh - rk = -1 ⇒ same value of b
∵ (hx - r)(kx + s)
∴ 2a² - a - 3 = (2a - 3)(a + 1)
∵ 2a² - 5a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 1 × 3 then r = 1 , s = 3
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 1
∵ sh = 6
∴ rk - hs = -5 ⇒ same value of b
∵ (hx + r)(kx - s)
∴ 2a² - 5a - 3 = (2a + 1)(a - 3)
∵ 2a² + a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 3 × 1 then r = 3 , s = 1
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 3
∵ sh = 2
∴ rk - sh = 1 ⇒ same value of b
∵ (hx + r)(kx - s)
∴ 2a² + a - 3 = (2a + 3)(a - 1)
3 out of every 5 picks are orange. If 12 picks are orange,how many picks are they in all
Answers
Answer: The answer to your question is 20
Step-by-step explanation: We know that 3 out of every 5 picks are oranges. And if the next 12 picks are orange, what is the total number of oranges in all?
So first, you would set up a proportion, which would look like this:
3 oranges/ 5 picks = 12 oranges/ x picks
Let the number of picks be known as x, our variable, since we don't know how many oranges are there total.
Next, when you have a proportion that you are trying to solve, the best thing to do is cross multiply, which will look this:
3x = 12(5)
3x = 60
3x/3 = 60/3
x=20 picks
Therefore, the answer is 20 picks

Step-by-step explanation:
Ok, thanks for the complement of information.
So, to find the volume of that step, which is a rectangular prism, we would use the simple formula:
V = length * width * height
In this case, we have the total volume (3,500 cu in), we have the width (10 inches) and we have the height (8 inches). But we need to find out the new length in order for him to use all 3,500 cu in of cement.
So, we transform the formula above into:
length = V / (width * height)
then we plug-in the numbers:
length = 3,500 / (8 x 10) = 3,500 / 80 = 43.75
So, the new length of the step would be 43.75 inches or 43 and 3/4 inches.

Answer:-
Q no.8 :
9, 13, 17 can merely be the correct option.
Explanation:-
• The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.
For instance:-
1) Calculation: 9 + 13 = 22 which is greater than the third side (the hypotenuse) that was 17. And hence is correct.
2) Calculation: 10 + 10 = 20 which is equal to the third/hypotenuse side that was also 20. Therefore it doesn’t fit the theorem and is unable to form a triangle.
3)Calculation: 6+8 = 14 which is less than the greatest/hypotenuse/third side or the side of measure 15. Thence, it isn’t the correct also. No accurate triangle can be formed from all these(6, 8, 15) measurements.
4) Calculation: 2+3 = 6 which is equal to the third /hypotenuse side of measure 6 also. And therefrom no triangle can be constructed from the given sides(2, 3, 6).
• The third important property of triangles is the triangle inequality rule, which states:
“The length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides”.

V =1205.76 units ^3
Step-by-step explanation:
Volume of a cylinder is given by
V = pi r^2 h
where r is the radius and h is the height
V = pi (8)^2 *6
V = pi (64)*6
V =384 pi units ^3 (exact answer)
or is we used 3.14 for pi
V = (3.14) * 384
V =1205.76 units ^3
