The intersection of plane TUYX and plane VUYZ is found as UY.
Define the term intersection of plane?In geometry, a plane is a flat plate that, from all angles, extends to infinity. Non-parallel planes that intersect together in line are known as intersecting planes. A line is formed by the connection of two planes. The planes are parallel if they do not intersect. Due to the endless nature of planes, they cannot connect at a single place.For the stated question-

2. How much does he need to charge if he wants to make a profit of $600?
He need to charge 24$ per tree if he wants to make a profit of $600.
According to statement
Noah knows that his profit, P, in dollars, are P= −3x^2 + 150 − 1200.
Now, we find the value of x when the profit is $600
Where X represent the Amount he charges per tree.
The given equation is P= −3x^2 + 150 − 1200.
Substitute the value of p is $600 in the above written equation
Then
600 = −3x^2 + 150 − 1200.
After solving the equation by a substitution method the value of X becomes

John is looking at the top of a building and thinking it would be great to make a zipline from the top to your current location. He measures the angle of elevation as 28and is 182 feet from the base of the buildingHow long a zipline is needed if John is 71.5 inches tall? Include a sketch that shows all known information and clearly shows what you need to findShow all work and give the answer rounded to the nearest tenth of a foot
Answer:
Step-by-step explanation:
sin(28) = 2184 / x
x= 2184/ sin(28) = 2184 / 0.4694 = 4652.75
4652.75 / 12 = 387.7 ft
ANSWER: 387.7ft
In the given case, The length of the zipline needed is approximately 96.7 feet.
To find the length of the zipline needed, we can use trigonometry. Let's start by drawing a sketch to visualize the problem. | | zipline | | | | | | | | | | John | Building 28°
John's location, with the angle of elevation labeled as 28°. John is 182 feet away from the base of the building, and he is 71.5 inches tall.
To find the length of the zipline, we can use the tangent function.
The tangent of an angle is equal to the ratio of the opposite side to the adjacent side.
In this case, the opposite side is John's height, and the adjacent side is the distance between John and the building. Using the tangent function, we have: tan(28°) = opposite / adjacent
We want to find the length of the zipline, which is the hypotenuse of the right triangle formed by John, the building, and the zipline. Let's call this length "x".
Therefore, we can rewrite the equation as: tan(28°) = 71.5 inches / 182 feet To solve for x, we need to convert the units so that they match.
Let's convert inches to feet: 71.5 inches = 71.5 inches * (1 foot / 12 inches) ≈ 5.96 feet (rounded to the nearest hundredth)
Now, let's solve for x: tan(28°) = 5.96 feet / 182 feet
To isolate x, we can multiply both sides by 182 feet: x ≈ tan(28°) * 182 feet Using a calculator, we find that tan(28°) ≈ 0.5317.
Multiplying this by 182 feet, we get: x ≈ 0.5317 * 182 feet ≈ 96.7 feet (rounded to the nearest tenth) .

The 680 tons of fuel needed to cover the next 1790 miles distance.
According to the statement
We have given that the ship covered a 1651 miles distance at 20 knots by a 580 tons of fuel oil.
And distance remaining to next port is 1790 miles and speed increases to 25 knots.
And we have to find that how much fuel used to reach that port.
So, Distance covered = 1651 mile
fuel used = 580 tons
distance covered with 1 tons fuel = 1651/580
distance covered with 1 tons fuel = 2.85 mile at a speed of 20 knots.
so, The fuel consumption for 1790 mile is = 1790/2.85

How to determine the other parallel side?The given parameters are:
Midsegment= 2x
One parallel side = x
The midsegment is calculated as:
Midsegment = 0.5 * (sum of parallel sides)

What is the standard equation for the circle with center (1,-3) that passes through the point (2,2)?
The standard equation for the circle is (x - 1 ) ^2 + (y + 3)^2 = 2 ^2
A circle is a closed curve that is drawn from a fixed point called the center in which all points on the curve are the same distance from the center of the center. The equation of a circle with center (h, k) and radius r is given by:
(x-h)^2 + (y-k)^2 = r^2
This is the standard form of the equation. So if we know the coordinates of the center of the circle and also its radius, we can easily find its equation.
Consider any point P(x, y) on the circle. Let "a" be the radius of the circle which is equal to OP.
We know that the distance between the point (x, y) and the origin (0,0) can be found using the distance formula which is equal to -
√[x^2+y^2]= a
Therefore the equation of a circle with center as origin is,
x^2+y^2= a^2
Where "a" is the radius of the circle.
An alternative method
Let's derive another way. Assume that (x,y) is a point on the circle and the center of the circle is at the origin (0,0). Now, if we draw a perpendicular from the point (x,y) to the x-axis, we get a right triangle, where the radius of the circle is the hypotenuse. The base of the triangle is the distance along the x-axis and the height is the distance along the y-axis. Applying the Pythagorean theorem here, we therefore obtain:
x^2+y^2 = radius^2
We need to find the standard equation for the circle with center (1,-3) that passes through the point (2,2)
Standard equation for circle is
(x-h)^2 + (y-k)^2 = r^2................(1)
Here h = 1 , k = -3 and r = 2
put this value of h, k and r in equation (1), we get
(x - 1 ) ^2 + (y + 3)^2 = 2^2
Hence the standard equation of the circle is
(x - 1 ) ^2 + (y + 3)^2 = 2 ^2

Step-by-step explanation:
To factor x² + ax + b, look for two numbers whose sum is a and whose product is b.
The factorization of x² - a² is (x + a)(x - a).
x² + 5x - 14 = (x + 7)(x - 2)
x² - 3x - 54 = (x - 9)(x + 6)
x² + 8x + 12 = (x + 2)(x + 6)
x² - 11x + 30 = (x - 5)(x - 6)

y = x² -3x - 54y = x² -9x +6x - 54
y = x(x -9) +6(x -9)
y = (x +6)(x -9)
y = x² +8x + 12y = x² +6x +2x +12
y = x(x +6) +2(x +6)
y = (x +2)(x +6)
y = x² -11x +30y = x² -6x -5x +30
y = x(x -6) -5(x -6)
y = (x -5)(x -6)
y = x² - 25y = (x +5)(x -5)

μ - mean, σ - standard deviation, n - sample size, and z - critical value.
The critical value is calculated by
step 1: 100% - (the confidence level)
step 2: Converting the step 1 result into decimal value
step 3: dividing the step 2 result by 2
This is indicated by α/2. So, from the normal distribution table, the z-value at α/2 is said to be the required critical value and denoted by Z_(α/2) or Z.
Calculation:It is given that,
A survey of several 10 to 11-year-olds recorded the following amounts spent on a trip to the mall: $18.31,$25.09,$26.96,$26.54,$21.84,$21.46
Sample size n = 6
Step 1: Finding the mean for the given amounts of the survey:
Mean μ = (18.31 + 25.09 + 26.96 + 26.54 + 21.84 + 21.46)/6
= 23.36
Step 2: Finding the standard deviation:
Standard deviation σ = √summation(x - mean)²/n
On calculating, we get σ = 3.09
Step 3: Finding the critical value:
It is given that the confidence level is 98%
So, (100% - 98%) = 2%
Converting into decimal gives 0.02
So, α/2 = 0.02/2 = 0.01
Thus, at 0.01, the critical value Z = 2.326
Step 4: Constructing the confidence interval:
C.I = 23.36 ± (2.326) × (3.09/√6)
= 23.36 ± (2.326 × 1.261)
= 23.36 ± 2.933
So, the lower bound = 23.36 - 2.933 = 20.427
the upper bound = 23.36 + 2.933 =26.293
Therefore, the 98% confidence interval lies from 20.427 to 26.293.
