In standard position, 2.280° refers to an angle in the Cartesian plane with its beginning side on the positive x-axis and its terminal side establishing an angle of 2.280° with the positive x-axis counterclockwise.
What is angle?An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles. An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.

In the following diagram, BC is parallel to DE. If AB=21, BD=7, and BC=15 then which of the following is the length of DE ? (1) 5 (2)10 (3) 20 (4) 25
The length of DE is 25. So correct option is (4).
What do you mean by parallel?In geometry, the term "parallel" refers to two lines that are equidistant from each other over their entire length and will never intersect, no matter how far they are extended. In other words, two parallel lines are parallel if they lie in the same plane and maintain the same distance between them at all times.
Since AB is parallel to DE and BD is perpendicular to both AB and DE, by alternate interior angles, we have:
angle BDA = angle DEC
Since BD is 7 and BC is 15, we have:
triangle BCD is a 7-15-17 right triangle (the Pythagorean theorem)
So, angle BDA = angle DEC = 90 - arctan(7/15) = arctan(15/7).
Also, since AB is parallel to DE, and BD is perpendicular to both AB and DE, we have:
angle ABD = angle CDE
So, by the vertical angles theorem, we have:
angle ABD = angle CDE = 90 degrees - arctan(15/7) = arctan(7/15)
Then, by the Pythagorean theorem, the length of DE can be found as:
[tex](DE)^{2}[/tex] = [tex](AB)^{2}[/tex] + [tex](BD)^{2}[/tex] = [tex]21^{2}[/tex] + [tex]7^{2}[/tex] = 441 + 49 = 490
So, DE = [tex]\sqrt{490}[/tex] = 2[tex]\sqrt{122}[/tex] = 2 * 11 = 22
Therefore, the length of DE is (4) 25.

1. The given trapezium is an isosceles trapezium, hence:
J = K = 7x + 2
M = L = 25x - 14
Since trapezium is a part of parallelogram, then:
∠J + ∠K + ∠L + ∠M = 360°
2∠J + 2∠M = 360°
2(7x + 2) + 2(25x - 14) = 360°

The exponential equation is P = 7000 * (1 + 0.08)ᵗ and the nearest whole number.
What is the exponential equation?
In combinatorial mathematics, the exponential formula (called the polymer expansion in physics) states that the exponential generating function for structures on finite sets is the exponential of the exponential generating function for connected structures.
a. To write the exponential equation, let t be the number of years and let P be the amount of money in the account after t years. The exponential equation can be written as:
P = 7000 * (1 + 0.08)ᵗ
b. To solve for t, we need to find the number of years it takes for P to reach $30,100. We can set up an equation and solve for t:
30,100 = 7000 * (1 + 0.08)ᵗ
Dividing both sides by 7000:
30,100 / 7000 = (1 + 0.08)ᵗ
Taking the natural logarithm of both sides:
ln (30,100 / 7000) = t * ln (1 + 0.08)
Solving for t:
t = ln (30,100 / 7000) / ln (1 + 0.08)
Using a calculator, we get:
t = 21.1397
Rounding up to the nearest whole number, it will take Fred 22 years to have $30,100 for a new car.
Hence, the exponential equation is P = 7000 * (1 + 0.08)ᵗ and the nearest whole number.

How much money needs to be set aside today to purchase a new piece of equipment in 3 yrs? The money is expected to 9% interest compounded annually and the piece of equipemt is expected to increase by 3% per year. The present cost of the equipment is $75,000.00.
To calculate the amount of money that needs to be set aside today to purchase a new piece of equipment in 3 years, we need to find the future value of the equipment and calculate the present value of that future amount.
First, let's find the future value of the equipment:
The cost of the equipment is expected to increase by 3% per year, so after 3 years the cost will be:
$75,000 * (1 + 0.03)^3 = $78,225
Next, let's find the present value of that future amount:
The money is expected to earn 9% interest compounded annually, so to find the present value, we need to discount the future amount by the interest rate. We can use the formula:
PV = FV / (1 + r)^t
where PV is the present value, FV is the future value, r is the interest rate, and t is the number of years.
Plugging in the values, we get:
PV = $78,225 / (1 + 0.09)^3 = $73,232.57
So, to purchase the equipment in 3 years, we need to set aside $73,232.57 today.
After Julia has driven for a quarter of an hour, she was 170 miles east from Denver. After driving for 3 hours, she was only 100 miles east from Denver. Assume that Julia drove at a constant speed during the trip. Let be a function that gives Julia’s position east from Denver (measured in miles) after having driven for hours.
a) Determine a rule for the function .
b) Interpret the meaning of ^−1(16) and then find its value if it exists.
c) Interpret the meaning of ^−1(-141) and then find its value if it exists.
d) Determine a rule for ^−1 .
e) Construct a graph for ^−1 .
The rule for the function is P(t) = 170 + 680t
The time t after which Julia is 16 miles east from DenverThe time t after which Julia is -141 miles east from DenverThe inverse is P^-1(t) = (t - 170) / 680a) Determine a rule for the functionLet's call Julia's final position after t hours as P.
If she drove at a constant speed v (in miles per hour), then the distance traveled can be given as:
P - P0 = vt
Given that she was 170 miles east from Denver after driving for a quarter of an hour (0.25 hours), we can write the first equation:
170 = v * 0.25
v = 680
This means that her speed was 680 miles per hour.
Using this speed, we can write the second equation:
P = 680 * t
100 = 680 * t
t = 100 / 680 = 0.147
Combining the two equations, we can find the function that gives Julia's position east from Denver after t hours as:
P(t) = P0 + v * t ----- P0 = 170 i.e. her initial position
P(t) = 170 + 680 * t
So, the rule for the function P(t) is:
P(t) = 170 + 680t
The meaning of P^-1(16)P^-1(16) is the inverse of the function P(t) at the value 16.
In other words, it gives us the time t after which Julia is 16 miles east from Denver.
To find its value, we can use the equation of the function P(t):
P(t) = 170 + 680 * t
16 = 170 + 680 * t
-154 = 680 * t
t = -154 / 680
Time cannot be negative.
So, it does not exist
The meaning of P^-1(-141)P^-1(-141) is the inverse of the function P(t) at the value -141.
In other words, it gives us the time t after which Julia is 16 miles east from Denver.
So, we have
-141 = 170 + 680 * t
-311 = 680 * t
t = -311 / 680
Time cannot be negative.
So, it does not exist
Determine a rule for ^−1 .We simply make t the subject in P(t)
So, we have
P^-1(t) = (t - 170) / 680

For a period of time, an island's population grows at a rate proportional to its population. If the growth rate is 3.8% per year and the current population is 1543, what will the population be 5.2 years from now
Step-by-step explanation:
To solve this problem, we'll use the exponential growth formula:
P(t) = P0 * e^(rt)
Where P(t) is the population after t years, P0 is the initial population (1543), r is the growth rate (0.038), and t is the number of years (5.2).
P(5.2) = 1543 * e^(0.038 * 5.2)
Using a calculator or natural logarithm rules:
P(5.2) = 1543 * e^0.199
P(5.2) = 1543 * 1.22
P(5.2) = 1887.46
So the population will be approximately 1887.46 after 5.2 years.

that means every point is a solution.
there are infinitely many solutions.
5x - 2y = 4
5x - 2y = 6
inconsistent
both equations are lines with identical slopes.
but with different y-intercepts.
they are parallel and never intersect.
there is no solution.
there is no (x, y) that their sum has 2
different results.
