What does [8+(2*12)]*2 equal?
Answer:
64
Step-by-step explanation:
take 2x12=24+8=32x2=64
Answer:
64 is the answer.
Step-by-step explanation:
To solve this problem, you need to follow the rules of PEMDAS.
That means what is the the parentheses is solved first, then exponents, then you solve the multiplication and division, and then you solve the addition and subtraction.
2*12 is the most specific parentheses, therefore it is solved first.
2*12 equals 24.
The problem is now
[8+24] *2
Then you add 8 and 24, which is also in the parentheses.
8 + 24= 32
The problem is now :
32*2
Then you solve the multiplication.
32*2= 64
Therefore the answer is 64.

P.S. Hello from Russia :^)
Which of the following points is on the circle given
by the equation (x − 5)2 + (y + 3)2 = 25?
A. (5, −3)
B. (8, −6)
C. (2, 1)
D. (4, −8)
Final answer:
The correct point that lies on the circle defined by the equation (x − 5)² + (y + 3)² = 25 is point C (2, 1), as substituting these values into the equation results in 25, which matches the right side of the equation. Thus, option C is correct.
Explanation:
To find which point is on the circle given by the equation (x − 5)² + (y + 3)² = 25, you can plug the x and y values from each option into the equation and see if it holds.
For point A (5, − 3), the equation becomes (5 − 5)² + (− 3 + 3)², which simplifies to 0 + 0 = 0. This is not equal to 25, so point A is not on the circle.
For point B (8, − 6), the equation becomes (8 − 5)² + (− 6 + 3)², which simplifies to 9 + 9 = 18. This is not equal to 25, so point B is not on the circle.
For point C (2, 1), the equation becomes (2 − 5)² + (1 + 3)², which simplifies to 9 + 16 = 25. This is equal to 25, so point C is on the circle.
For point D (4, − 8), the equation becomes (4 − 5)² + (− 8 + 3)², which simplifies to 1 + 25 = 26. This is not equal to 25, so point D is not on the circle.
The correct answer is point C (2, 1), as it satisfies the equation of the circle.

Prove that in the plane the perpendicular bisector of a chord in a circle contains the center of the circle
The perpendicular bisector of a chord in a circle contains the center of the circle.
Explanation:To prove that the perpendicular bisector of a chord in a circle contains the center of the circle, we can use the fact that the perpendicular bisector of a chord passes through the center of a circle.
Let ABC be a chord in a circle with center O. We want to show that the perpendicular bisector of AB passes through O.
Since AB is a chord, it intersects the center O. Let P be the midpoint of AB. The line segment OP is a radius of the circle, and the line segment AB is perpendicular to OP at P. Therefore, the perpendicular bisector of AB passes through O, the center of the circle.

Answer:
B 396
Step-by-step explanation:
y = 4x + 11
y = -2x - 1
Answer:
x = -2, y= 3
Step-by-step explanation:
y = 4x + 11
y = -2x - 1
Because both equations are equal to y, we can set them equal to each other
4x + 11 = -2x - 1
Add 2x to each side
4x+2x +11 = -2x+2x -1
6x +11 = -1
Subtract 11 from each side
6x+11-11=-1-11
6x = -12
Divide each side by 6
6x/6 = -12/6
x = -2
Now we need to find y
y = -2x-1
y = -2(-2)-1
=4-1

What is the distance between the points (4,-2) and (-1,10)?
A. 5 units
B. 6 units
C. 12 units
D. 13 units
Answer:
D. 13 units
Step-by-step explanation:
The distance between the points (4,-2) and (-1,10) is 13 units.
Explanation:To find the distance between two points, we can use the distance formula. The distance formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the coordinates of the first point are (4, -2) and the coordinates of the second point are (-1, 10). Plugging these values into the distance formula, we get:
d = sqrt((-1 - 4)^2 + (10 - (-2))^2) = sqrt((-5)^2 + (12)^2) = sqrt(25 + 144) = sqrt(169) = 13 units
Therefore, the distance between the points (4, -2) and (-1, 10) is 13 units.

Joan deposited $550 into her savings account for two years. She received 1.8% simple
interest on her money. How much money did she have at the end of the two year term?
Answer:$569.8
Step-by-step explanation:
To find the amount received for$550 deposited for 2yrs at 1.8% per annum
I=prt/100
I=550×1.8×2/100
I=$19.8
To find the whole money deposited after 2yrs

Which are the roots of the quadratic function f(q) = q^2 - 125? Select two options.
q= 5/5
q = -5/5
q=375
q=-3/5
q = 2575
Answer:
None of the options are correct
Step-by-step explanation:
Given
[tex]f(q) = q^2 - 125[/tex]
Required
The roots of the function
Since the function is a quadratic function; to get the roots of the function, f(q) must be equal to 0
[tex]f(q) = q^2 - 125[/tex] becomes
[tex]0 = q^2 - 125[/tex]
Make [tex]q^2[/tex] the subject of formula
[tex]125= q^2[/tex]
Rearrange
[tex]q^2 = 125[/tex]
Take square roots of both sides
[tex]\sqrt{q^2} = \sqrt{125}[/tex]
[tex]q = \sqrt{125}[/tex]
Expand the square root of 125
[tex]q = \sqrt{25 * 5}[/tex]
[tex]q = \sqrt{25} * \sqrt{5}[/tex]
q = ±5 [tex]* \sqrt{5}[/tex]
Split into 2
[tex]q = 5 * \sqrt{5}[/tex] or [tex]q = -5 * \sqrt{5}[/tex]
[tex]q = 5 \sqrt{5}[/tex] or [tex]q = -5 \sqrt{5}[/tex]
Hence, the roots of the quadratic function are [tex]q = 5 \sqrt{5}[/tex] or [tex]q = -5 \sqrt{5}[/tex]

What integers are plotted on the number line below?
Hey there!
We can see on this number line that each tick mark represents one because every five marks, there is a difference of five.
Two marks to the left of 0 will be 0 minus 2, so -2.
Three marks to the left of -5 will be -5 minus 3, so -8.
Your answer is -8 and -2.
Hope this helps!
Final answer:
The integers that are being referred to are -8 and -2, which are negative whole numbers located on the left side of zero on a number line.
Explanation:
When plotted on the number line, integers represent whole numbers that can be positive, negative, or zero.
To identify the integers that are plotted, one would look for distinct marks or points on the number line that correspond to whole numbers.
Based on the data, we come to the conclusion that the numbers in question are -8 and -2.
The integers plotted on the number line are -8 and -2. The integer -8 is to the left of -2 on the number line.
These two numbers are examples of negative integers, which are located to the left of zero on a standard number line. The understanding of how to read a number line and identify the placement of integers is a key concept in mathematics, which allows for better comprehension of more complex mathematical ideas such as rational numbers, real numbers, and complex numbers.

What is a circle?A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.
Given that, a circle is divided into 4 slices. The slices are arranged into the shape.
So, when we will cut the circle into similar manner, the shape we will get closer to will be a rectangle,
When we will calculate the perimeter and the area of the obtained rectangle, it will be equal to the circle.

Final answer:
When a circle is divided into more and more slices and these slices are rearranged, they approximate a circle more closely. While a hexagon may seem like a closer shape due to the angles of its vertices, the ultimate shape remains a circle.
Explanation:
If a student rearranges the slices from a circle cut into more slices, they would get a shape that approximates a circle more closely as the number of slices increases. As each slice becomes thinner, the perimeter of the rearranged shape starts resembling a smooth curve, which is the characteristic of a circle.
Looking at the angles provided, a triangle has 60° angles, a square has 90° angles, a pentagon has 108° angles, and a hexagon has 120° angles. The figures suggest that a hexagon would be a more favorable shape when arranging slices because the angles of a hexagon (120°) are closer to the 360° of a full circle when divided by an increasing number of slices. However, when arranging the slices, the ultimate shape one gets closer to is the circle itself, irrespective of the polygonal shape intermediate stages may suggest.
