A Circular pie with a diameter of 10” Is cut into six equal pieces. What is the surface area of two slices of pie?
To solve this question, let's find the surface area of the entire pie and then divide it by 6 for each slice.
The area of a circle is pi*r^2. We are given the diameter, so divide that by 2 to get the radius.
Now that you have the area, divide by 6. That is the area of each slice. The problem asks for the area of 2 slices though, so multiply that by 2.

Which of the following transformations will result in an image that maps onto itself?
A. rotate 180 degrees counterclockwise and then reflect across the y-axis
B. reflect across the y-axis and then reflect again across the y-axis
C. rotate 90 degrees counterclockwise and then rotate 270 clockwise
D. reflect across the y-axis and then reflect across the x-axis
If we reflect across the y-axis and then reflect again across the y-axis , it will give result an image that maps onto itself , Option B is the right answer.
What are the rules of Transformations ?The reflection of the point (x,y) across the x-axis is the point (x,-y), across the y-axis is the point (-x,y). , across the line is the point (y, x)
The 90 degree counterclockwise rotation of a point (x, y) is the point (-y, x)
The 180 degree counterclockwise rotation of a point (x, y) is the point (-x, -y)
The 270 degree clockwise rotation of a point (x, y) is the point (-y, x)
Therefore on application of these rules
For Case A
The point will be (-y , x)
For Case B
The point will be (x,y)
Therefore Option B is the answer.

What is a triangular prism?Suppose you've got a triangle. Now, stretch it up so as to make a stack of triangles up above another. This new 3d object is called a triangular prism.
Usually, when we talk about a triangular prism, we talk about the triangular prism, whose stack goes straight up, thus, we talk about a right triangular prism.
The area of the triangular prism is the sum of the area of the rectangle and the area of the triangle, therefore, the area of the prism will be,
Area = A + B + C
=(9 × 15) + (0.5×6×3) + (0.5×6×3)
= 135 + 9 + 9
= 153 cm²

How many solutions does the system of equations have?
y=-2x+3
y = x² - 6x +3
Answer:
2 solutions
Step-by-step explanation:
y = - 2x + 3 → (1)
y = x² - 6x + 3 → (2)
substitute y = x² - 6x + 3 into (1)
x² - 6x + 3 = - 2x + 3 ( subtract - 2x + 3 from both sides )
x² - 4x = 0 ← factor out x from each term on the left side
x(x - 4) = 0
equate each factor to zero and solve for x
x = 0
x - 4 = 0 ⇒ x = 4
substitute these values into (1)
x = 0 : y = - 2(0) + 3 = 0 + 3 = 3 ⇒ (0, 3 )
x = 4 : y = - 2(4) + 3 = - 8 + 3 = - 5 ⇒ (4, - 5 )
the 2 solutions are (0, 3 ) and (4, - 5 )

Without using the formula, work out the gradient of the graph shown.
Reason:
Start at the y intercept (0,4) which is where the red line crosses the y axis.
Then move up 2 units, and to the right 1 unit to arrive at (1, 6) which is another point on this red line.
The motion of "up 2, right 1" means:
rise = 2run = 1gradient = slope = rise/run = 2/1 = 2Feel free to use any other two points you prefer and you should get the same result. For instance, you could have started at the x intercept (-2,0) and did the "up 2, right 1" motion to arrive at (-1, 2).

Which pair of events are called independent events?When one event's occurrence or non-occurrence doesn't affect the occurrence or non-occurrence of another event, then such events are called independent events.
Symbolically, we have:
Two events A and B are said to be independent iff we have:
[tex]P(A \cap B) = P(A)P(B)[/tex]
Comparing it with chain rule will give
[tex]P(A|B) = P(A)\\P(B|A) = P(B)[/tex]
Thus, showing that whether one occurred or not, the other one doesn't care about it (independence).
Two events are known to be independent even if the result of one event does not affect the result of the second event.
Rolling a dice in an independent event and choosing a blue marble is another independent event. The two events are independent and the result of one does not affect the other.
Thus, A is correct.
Rolling a dice in an independent event, and rolling it again won't affect the result of the second roll. Therefore, rolling a dice twice or for n number of times is an independent event.
Thus, B is correct.
Hence, the correct options are A and B.

quadratic equation y= (x+4)^2 -2
I need to know if it’s Max or min
Domain
Range
Increasing interval
Decreasing interval
Whoever the first correct answer belongs to gets a crown :) tysmmm
Answer:
Max or Min: min
Domain: (−∞, ∞)
Range: (−2, ∞)
Increasing interval: (−4, ∞)
Decreasing interval: (−∞, -4)
Step-by-step explanation:
Max or Min: You determined that the curve opens upwards meaning that the vertex is at the min. If it opened down then it would be at the max.
In mathematical terms: if a > 0, the parabola opens upward and the vertex is a minimum. If a < 0, the parabola opens downward, and the vertex is a maximum.
Domain: This is all possible x values, since the parabola is upwards its going to have any possible x values
Range: this is all possible y values. we know that the vertex point (min) doesn't go less than the value of -2 for y but anything above is possible hence -2 is the lowest possible y value and anything beyond above
Increasing interval: The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I.
Decreasing interval: The derivative, then set it equal to 0, and then find between which zero values the function is negative.

Which statement about the angles in the figure is true?
m/3+m/5= 180°
m/7+m/10 = 180°
m/8+m/9 = 90°
m/1+m/8= 90°
The true statement about the angles in the figure is m∠1 + m∠8 = 90°. The correct option is the last option m∠1 + m∠8 = 90°
Determining the measures of anglesFrom the question, we are to determine the statement that is true about the angles in the given figure
In the given diagram, we can observe that
m∠3 + m∠8 + m∠9 + m∠10 = 180° (Sum of angles in a triangle)
Also,
m∠3 = m∠1 (Vertically opposite angles)
m∠9 + m∠10 = 90° (Vertically opposite angles)
∴ m∠1 + m∠8 + 90° = 180°
m∠1 + m∠8 = 90°
Hence, the true statement about the angles in the figure is m∠1 + m∠8 = 90°. The correct option is the last option m∠1 + m∠8 = 90°
