A straw is placed inside a rectangular box that is 3 inches by 2 inches by 9 inches, as shown. If the straw fits exactly into the box diagonally from the bottom left corner to the top right back corner, how long is the straw? Leave your answer in simplest radical form.
The diagonal of the rectangular box will be 9.7 inches.
Given that:
Length, L = 3 inches
Width, W = 2 inches
Height, H = 9 inches
The diagonal of the rectangular prism is given as,
d² = L² + W² + H²
The diagonal of the rectangular box will be calculated as,
d² = 3² + 2² + 9²
d² = 9 + 4 + 81
d² = 94
d = √94
d = 9.7 inches
The diagonal of the rectangular box will be 9.7 inches.

Colton is flying a kite, holding his hands a distance of 3 feet above the ground and
letting all the kite's string play out. He measures the angle of elevation from his hand
to the kite to be 32°. If the string from the kite to his hand is 90 feet long, how many
feet is the kite above the ground? Round your answer to the nearest hundredth of a
foot if necessary.
The height of the kite above the ground is; approximately 50.69 feet.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
The height of his hands above the ground, h is given by 3 feet
Angle of elevation of the string (above the horizontal), θ = 32°
Length of the string, l is given as 90 feet
The height of the kite above the ground is given by trigonometric ratios as ;
Sin∅ =h /90
Sin 32°= h/90
0.52 =h /90 (Sin32°= 0.52)
so h= 47.69 feet
Then height from ground is (H) = 3 +47.69
H = 50.69 feet
The height of the kite above the ground , ≈ 50.69 feet

Let X and Y be discrete random variables and let a and b be constants Which of the following is. FALSE? (a) mean (X + Y) = mean (X) + mean (Y).
Mean (X + Y) = Mean (X) + Mean (Y).
The above statement is false.
Discrete Random Variable:
A discrete random variable can be defined as a type of variable whose value depends on the numerical outcome of some random phenomenon. Also called a random variable. Discrete random variables are always easily countable integers. A probability mass function is used to describe the probability distribution of a discrete random variable.
Probability Distributions of Discrete Random Variables:
Probability distributions of discrete random variables list the probabilities associated with each possible outcome. Also called probability function or probability mass function.
The probability of a discrete random variable is between 0 and 1. Also, the sum of the probabilities of a discrete random variable is equal to 1. The probability distribution of discrete random variables resembles the normal distribution.
Example:
Suppose two dice are rolled and a random variable X is used to represent the sum of the numbers. The minimum value of X goes from result 1 + 1 = 2 to 2 and the maximum value goes from result 6 + 6 = 12 to 12. Therefore, X can have any value between 2 and 12 (inclusive). If probabilities are assigned to each outcome, we can determine the probability distribution of X.
Discrete random variables should not be confused with algebraic variables. Algebraic variables represent the values of unknown quantities in computable algebraic equations. However, a discrete random variable can have a range of possible values that result from experimentation.

Step-by-step explanation:
How do you solve this? Without going into anything to complicated as this should be Year 10 maths
Given : ABCD is a square with each side 5cm .
To Find : The area of the shaded region .
Solution : On observing the figure we can see two quadrants , quadrant ADC & quadrant ABC .
If we join A to C , then it will be common for triangles ADC & ABC . And they will be congruent by SSS congruence condition.
Therefore the area of both quadrants will also be equal . Now we can find area of quadrant as ;
\(\large\boxed{\red{\bf Area_{quadrant}=\dfrac{\pi r^2}{4}}}\)
Here radius will be equal to 5cm .
⇒ Area = πr² / 4 .
⇒ Area = π (5cm)² / 4 .
⇒ Area = 22/7 × 25 × 4 cm².
⇒ Area = 19.64 cm² .
So , total area of both quadrants = 39.28 cm² .
Also , area of square will be :
\(\large\boxed{\bf{\red{Area_{square}=(side)^2}}}\)
⇒ Area = 5cm × 5cm .
⇒ Area = 25 cm².
Now , subtract area of one quadrant from the area of square = 25cm² - 19.64 cm² = 5.36 cm².
Similarly area of other white region = 5.36cm² .
And the areas sum will be = 5.36cm² × 2 = 10.72cm² .
Now , from the figure it's clear that ,
⇒ Area of unshaded region + Area of shaded region = 25cm².
⇒ 10.72cm² + ar( Shaded region ) = 25cm².
⇒ ar ( Shaded region ) = 25cm² - 10.72cm².
⇒ ar ( Shaded region ) = 14.28 cm².
Hence the area of shaded region is 14.28 cm².
\(\large\boxed{\red{\bf Answer = 14.28cm^2}}\)

(please also show an step by step process of getting EAF!)
Answer:
x = 27 , ∠ EAF = 27°
Step-by-step explanation:
∠ GAF = 90° , then
∠ GAC + ∠ CAF = ∠ GAF , that is
x + 63 = 90 ( subtract 63 from both sides )
x = 27
∠ DAE = 90°
since CD is a straight angle of 180° , then
∠ CAE = 90° , so
∠ CAF + ∠ EAF = ∠ CAE , that is
63° + ∠ EAF = 90° ( subtract 63° from both sides )
∠ EAF = 27°

COMPLEX NUMBERS (DE MOIVRE THEOREM) NEED HELP
a) These are the four solutions to the equation z⁴ = 1. We can plot these solutions on an Argand diagram by marking points at (1, 0), (0, 1), (-1, 0), and (0, -1).
b) These are the three solutions to the equation z³ = 8. We can plot these solutions on an Argand diagram by marking points at (2, 0), (-1, √3), and (-1, -√3).
c) These are the three solutions to the equation z³ = i. We can plot these solutions on an Argand diagram by marking points at (1, 0), (-1/2, √3/2), and (-1/2, -√3/2).
What is the explanation for the above results?
a) To find all solutions to the equation z⁴ = 1, we can use De Moivre's theorem:
z⁴ = 1 = cos(0) + i sin(0)
We can rewrite this in polar form as:
z = cos(0/4 + 2kπ/4) + i sin(0/4 + 2kπ/4)
where k = 0, 1, 2, 3.
Simplifying the expression for z, we get:
z = cos(kπ/2) + i sin(kπ/2)
For k = 0, we get z = 1.
For k = 1, we get z = i.
For k = 2, we get z = -1.
For k = 3, we get z = -i.
These are the four solutions to the equation z⁴ = 1. We can plot these solutions on an Argand diagram by marking points at (1, 0), (0, 1), (-1, 0), and (0, -1).
b) To find all solutions to the equation z³ = 8, we can use De Moivre's theorem:
z³ = 8 = 8(cos(0) + i sin(0))
We can rewrite this in polar form as:
z = 2(cos(0/3 + 2kπ/3) + i sin(0/3 + 2kπ/3))
where k = 0, 1, 2.
Simplifying the expression for z, we get:
z = 2(cos(kπ/3) + i sin(kπ/3))
For k = 0, we get z = 2.
For k = 1, we get z = -1 + i√3.
For k = 2, we get z = -1 - i√3.
These are the three solutions to the equation z³ = 8. We can plot these solutions on an Argand diagram by marking points at (2, 0), (-1, √3), and (-1, -√3).
c) To find all solutions to the equation z³ = i, we can use De Moivre's theorem:
z³ = i = cos(π/2) + i sin(π/2)
We can rewrite this in polar form as:
z = (cos(π/6 + 2kπ/3) + i sin(π/6 + 2kπ/3))
where k = 0, 1, 2.
Simplifying the expression for z, we get:
z = cos(kπ/3) + i sin(kπ/3)
For k = 0, we get z = 1.
For k = 1, we get z = (-1 + i√3)/2.
For k = 2, we get z = (-1 - i√3)/2.
These are the three solutions to the equation z³ = i. We can plot these solutions on an Argand diagram by marking points at (1, 0), (-1/2, √3/2), and (-1/2, -√3/2).

a) The transportation cost of 35 kg of potatoes is Rs 105. (i) What is the transportation cost of 2.5 quintals of potatoes at the same rate for the same distance? (ii) How many quintals of potatoes can be transported for Rs 1,500 at the same rate for the same distance?
(i) 1 quintal = 100 kg
2.5 quintals = 2.5100 = 250 kg
Transportation cost of 250 kg of potatoes = 105(250/35) = Rs 750
we are asked to find the transportation cost of 2.5 quintals (250 kg) of potatoes at the same rate as 35 kg of potatoes. We know that the transportation cost for 35 kg is Rs 105.
To find the cost for 250 kg, we use the proportion of 35/105 = x/750. By cross multiplying we get x= 250*105/35= 750. So the transportation cost for 250 kg of potatoes is Rs 750.
(ii) Transportation cost of 1 quintal of potatoes = 105*(100/35) = Rs 300
Transportation cost of 1 quintal of potatoes = Rs 1500 / Rs 300 = 5 quintals.
we are asked to find how many quintals of potatoes can be transported for Rs 1,500 at the same rate as 35 kg of potatoes. We first find the transportation cost of 1 quintal of potatoes by using the proportion of 35/105 = x/300.
So x = 100, thus the transportation cost of 1 quintal of potatoes is Rs 300. So we can transport 1 quintal of potatoes for Rs 300. Dividing 1500 by 300, we get 5 quintals.
