The vectors that join the center of a clock to the hours :
At 1:00: (cos(π/6), sin(π/6)) = (√3/2, 1/2)
At 2:00: (cos(π/3), sin(π/3)) = (1/2, √3/2)
At 3:00: (cos(π/2), sin(π/2)) = (0, 1)
What is Vector?
A vector is a object that has both magnitude (size) and direction. In other words, a vector is a quantity that can be represented by an arrow or line segment, where the length of the arrow corresponds to the magnitude of the vector.
To find the vectors that join the center of a clock with radius 1 unit to the hours 1:00, 2:00, and 3:00, we can use basic trigonometry.
First, we can find the angle (in radians) between the 12:00 position and each of the desired hour positions. Since there are 12 hours on a clock and the circle has a circumference of 2πr = 2π(1) = 2π, the angle between each hour mark is:
2π/12 = π/6 radians
Therefore, the angles between the center of the clock and the hour marks are:
At 1:00, the angle is π/6 radians clockwise from the 12:00 position.
At 2:00, the angle is 2π/6 = π/3 radians clockwise from the 12:00 position.
At 3:00, the angle is 3π/6 = π/2 radians clockwise from the 12:00 position.
Next, we can use the cosine and sine functions to find the x and y components of each vector. The x-component of each vector is given by the radius times the cosine of the angle, and the y-component is given by the radius times the sine of the angle.
Therefore, the vectors that join the center of the clock to the hours 1:00, 2:00, and 3:00 are:
At 1:00: (cos(π/6), sin(π/6)) = (√3/2, 1/2)
At 2:00: (cos(π/3), sin(π/3)) = (1/2, √3/2)
At 3:00: (cos(π/2), sin(π/2)) = (0, 1)
Note that these vectors are unit vectors, meaning that they have a length of 1 unit.

The length of the diagonal of the door is approximately 14.308 feet. Rounding to the nearest whole number, the answer is 14 feet.
Length of triangle calculation.
The lengths of the trim pieces that make an X on the door form the legs of a right triangle, and the diagonal of the door forms the hypotenuse of the right triangle. Using the Pythagorean theorem, we can find the length of the hypotenuse:
a^2 + b^2 = c^2
where a and b are the lengths of the trim pieces and c is the length of the hypotenuse.
Each trim piece forms a right triangle with the height of the door (7 feet) and one half of the width of the door (1.5 feet). Using the Pythagorean theorem, we can find the length of each trim piece:
a^2 + b^2 = c^2
where a = 7 feet and b = 1.5 feet
c = sqrt(a^2 + b^2) = sqrt((7 feet)^2 + (1.5 feet)^2) = sqrt(49 + 2.25) = sqrt(51.25) ≈ 7.154 feet
The length of each trim piece is approximately 7.154 feet. Since there are two trim pieces that intersect at the center of the door, the length of the hypotenuse is twice this length:
2 * 7.154 feet ≈ 14.308 feet
Therefore, the length of the diagonal of the door is approximately 14.308 feet. Rounding to the nearest whole number, the answer is 14 feet.

Find the first 3 terms of arithmetic sequence if t5=-154 and t9=-274. Find t1, t2, t3 ANSWER QUICKLY PLS
If for an arithmetic-sequence, the terms are t₅ = -154 and t₉ = -274, then the first-three terms are t₁ = -274, t₂ = -244 and t₃ = -214.
An "Arithmetic-Sequence" is defined as a sequence of numbers in which the difference between any two consecutive terms is always the same, which is called the "common-difference".
To find first 3 terms of an "arithmetic-sequence" given the values of t₅ and t₉, we use formulas for "nth-term" of an arithmetic sequence, which is
⇒ tₙ = t₁ + (n - 1)d,
where tₙ = nth term, t₁ = first term, n = position of term in sequence, and d = common-difference,
Given that t₅ = -154 and t₉ = -274,
So,
⇒ t₅ = t₁ + (5 - 1)d = -154,
⇒ t₉ = t₁ + (9 - 1)d = -274,
We first find the "common-difference" by subtracting "t₁" from both sides of first equation and "t₉" from both sides of second-equation,
We get,
⇒ 4d = -154 - t₁,
⇒ 8d = -274 - t₁,
Simplifying further,
We get,
⇒ 4d = 120,
⇒ d = 30,
Now, we substitute it in "4d = -154 - t₁",
We get,
⇒ 4(30) = -154 - t₁,
⇒ 120 = -154 - t₁,
⇒ t₁ = -154 - 120,
⇒ t₁ = -274
So, the first term is = -274;
Now we use "d = 30" to find second and third terms of sequence,
We get,
⇒ t₂ = t₁ + (2 - 1)d = -274 + 30 = -244,
⇒ t₃ = t₁ + (3 - 1)d = -274 + 60 = -214,
Therefore, first three-terms of arithmetic sequence are -274, -244, and -214.

Formula,example and definetion probability of simple event
The probability of a simple event is the likelihood or chance of that event occurring. The formula is P(A) = Number of favorable outcomes / Total number of possible outcomes.
It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
The formula for the probability of a simple event is:
P(A) = Number of favorable outcomes / Total number of possible outcomes
For example, if we toss a fair coin, the probability of getting heads is:
P(Heads) = 1 (number of favorable outcomes) / 2 (total number of possible outcomes)
So, the probability of getting heads is 0.5 or 50%.
A simple event is an event that has only one possible outcome. For instance, rolling a specific number on a dice, drawing a specific card from a deck of cards, or picking a specific colored ball from a bag of balls are all examples of simple events.

Find the lateral and total surface area of the prism
Lateral surface area = 2H(L + W)
Total surface area = 2 LW + 2 WH + 2 HL
How to find the lateral and total surface area of prism?We need to know the prism's dimensions in order to determine its lateral and total surface area for a rectangular base prism. The rectangular prism's length, width, and height are assumed to be L, W, and H, respectively.
The sum of the areas of the rectangular prism's four lateral faces determines its lateral surface area. Since every sidelong face is a square shape with a level of H and a width of one or the other L or W, the parallel surface region is given by:
Lateral Surface Area = 2H(L + W)
The sum of the areas on each of the six faces creates the rectangular prism's total surface area. This incorporates the four sidelong faces, as well as the top and base faces, which are additionally square shapes with aspects L x W. Consequently, the all out surface region is given by:
Total Surface Area = 2(LW + LH + WH)

(1 point) a spherical balloon is inflated so that its volume is increasing at the rate of 2.8 ft3/min . how rapidly is the diameter of the balloon increasing when the diameter is 1.5 feet?
The diameter of the balloon is increasing at a rate of approximately 0.79 ft/min when the diameter is 1.5 feet.
We can use the formula for the volume of a sphere to relate the rate of change of volume with the rate of change of diameter
V = (4/3)πr^3 = (1/6)πd^3,
where V is the volume, r is the radius, and d is the diameter.
Taking the derivative with respect to time t, we get
dV/dt = (1/2)πd^2 (dd/dt),
where dd/dt is the rate of change of diameter.
We are given that dV/dt = 2.8 ft^3/min and d = 1.5 ft, so we can solve for dd/dt
dd/dt = (2dV/dt)/(πd^2) = (2(2.8))/(π(1.5)^2) ≈ 0.79 ft/min.

Step-by-step explanation:
If you think math is boring, think again. Here is a fun way to learn how to find the rational number that we need to divide -15/56 by to get -5/7. It's like a puzzle, but with fractions!
First, we need to make -15/56 look nicer. How do we do that? By dividing both the top and the bottom by -1. That's like flipping the sign. So we get 15/56. Much better!
Next, we need to find a mystery number that makes -5/7 and 15/56 equal when we multiply them. That's like finding a missing piece of a jigsaw puzzle. How do we do that? By cross-multiplying! That's when we multiply the top of one fraction by the bottom of the other and set them equal. So we get:
-5 times 56 equals 15 times mystery number
Now we just need to solve for the mystery number. How do we do that? By dividing both sides by 15. That's like cutting a cake into equal slices. So we get:
Mystery number equals (-5 times 56) divided by 15
Now we just need to simplify. How do we do that? By using a calculator or our brains. Either way, we get:
Mystery number equals -18.67
And that's it! We found the rational number that we need to divide -15/56 by to get -5/7. It's -18.67. Isn't math fun?

What is centroid of a triangle?Point at which all three medians of a particular triangle meet is called as a centroid. Median also called as a line segment which connects the vertex of a triangle to the midpoint.
Since G is the centroid of ΔABC, it divides each median in the ratio of 2:1. That is,
AG:GE = 2:1, BG:GF = 2:1, CG:GD = 2:1
First, we know, AG/GE = 2/1 (given, AG = 20)
20 / GE = 2/1
GE = 10
So, given in the median of ΔABC is,
AE = AG + GE (put the values)
AE = 20 + 10
AE = 30
Now, we can use the fact that BG:GF = 2:1 to find the length of GF:
we know, BG/GF = 2/1 (given, BF = 30 = BG + GF)
BG = 2GF
(BF - GF) = 2GF (here, BG = BF - GF)
30 - GF = 2GF
GF = 10
Now, we can use the fact that CG:GD = 2:1 to find the length of GD:
we know, CG/GD = 2/1 (given, CG = 10)
10 / GD = 2/1
GD = 5
Therefore, we get the values are: AE = 30, GF = 10, GD = 5

a. For rectangular or square patios: Measure the length (L) and width (W) of the patio using a measuring tape. Ensure that the measurements are taken in the same unit (e.g., feet, meters, etc.).
b. For circular patios: Measure the diameter (D) or radius (R) of the patio. The radius is the distance from the center of the circle to any point on its edge.
c. For irregularly-shaped patios: Break the patio down into smaller, regular shapes (like rectangles, squares, or triangles), and measure each side of these smaller shapes.
Calculate the perimeter:
a. For rectangular or square patios: Use the formula P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.
b. For circular patios: Use the formula P = 2πR or P = πD, where P is the perimeter, R is the radius, and D is the diameter. π (pi) is approximately 3.14159.
c. For irregularly-shaped patios: Add up the side lengths of each smaller shape that you've broken the patio into. The sum of these lengths will give you the total perimeter.

Juanita covered the outside of a gift box shaped like a rectangular prism with the paper. The box is 3. 2 feet long and 2. 1 feet wide and 2. 7 feet high what could be the closest to the total to the surface area
The total surface area of a gift box is 42.06 square feet
We know that the formula for the surface area of rectangular prism is:
A = 2(lw + wh + lh)
where l is the length
w is the width
and h is the height
The box shaped like a rectangular prism is 3.2 feet long and 2.1 feet wide and 2.7 feet high.
⇒ l = 3.2 ft,
w = 2.1 ft
and h = 2.7 ft
Using above formula the total surface area of the box would be,
A = 2(lw + wh + lh)
A = 2 × [(3.2 × 2.1) + (2.1 × 2.7) + (3.2 × 2.7)]
A = 2 × 21.03
A = 42.06 square feet
Therefore, the required area is 42.06 square feet

Enter the length of curve DE given that the curve is 5% longer than line
segment AB.
The length of curve DE, which is 5% longer than line segment AB, is 10.5 units.
To calculate the length of curve DE, we first need to determine the length of line segment AB. Let's say, for example, that line segment AB has a length of 10 units. To find the length of curve DE, we need to add 5% of line segment AB's length to line segment AB.
To calculate 5% of line segment AB's length, we can multiply the length of line segment AB by 0.05. This gives us:
5% of 10 = 0.05 x 10 = 0.5
So, 5% of line segment AB's length is 0.5 units. To find the length of curve DE, we need to add 0.5 units to the length of line segment AB. This gives us:
Length of curve DE = Length of line segment AB + 5% of Length of line segment AB
= 10 + 0.5
= 10.5 units
