Determine the slope of a line that makes an angle of 5pi/4 radians with the x-axis.
Answers
π radians is the angle 180 degrees, so π/4 radians is 180°/4=45°.
to construct the angle [tex]5 \frac{ \pi}{4} [/tex] we can proceed as shown in the figure, that is, we open an angle equal to 5 half right angles.
We see that the line making the angle 5pi/4 is the same line making the angle pi/4 radians, that is 45 degrees.
A line making the angle 45 degrees with the x axis, has slope equal to 1.
Remark, we have considered a line passing through the origin, as it represents all other lines making 5pi/4 radians.

jill traveled to the ferry office and back. the trip there took 5 hours and the trip back took 4 hours. she averaged 65 mph on the return trip. find the average speed of the trip there
Answers
We know from physics class that the formula for distance of a linear motion is given as:
d = v t
Where,
d = distance travelled
v = average velocity
t = time it took to reach the destination
Since the distance going to the office and back is just similar, therefore we can simply equate the two:
v1 t1 = v2 t2
Where 1 signifies going to the office and 2 signifies going back from the office. Therefore this yields to:
v1 * 5 hours = 65 mph * 4 hours
v1 = 52 mph
Answer: The average speed going to the office is 52 mph.
The average speed of Jill's trip to the ferry office was 52 mph, calculated by dividing the distance of 260 miles by the time of 5 hours.
To find the average speed of the trip there, we need to know the distance Jill traveled to the ferry office. Since she averaged 65 mph on the return trip which took 4 hours, the distance is calculated as speed x time, which equals 260 miles (65 mph x 4 hours).
The distance to the ferry office is the same as the distance back, so Jill also traveled 260 miles on the trip there. Given that the trip there took 5 hours, we can find the average speed by dividing the distance by the time. The average speed is 260 miles / 5 hours, which equals 52 mph.

Step-by-step explanation:
We have right triangles.
Know the two sides of the triangle and need to find the third missing side.
In order to find the third side of the right triangle, we use pythagoras theorem.
It is,
(Hypotenuse)² = (base)² + (height)²
i)
13² = 12² + t²
169 = 144 + t²
t² = 25
t = 5.
ii)
12² = 9² + a²
144 = 81 + a²
144 - 81 = a²
a² = 63
a = √63
iii)
x² = 9² + 6²
x² = 81 + 36
x² = 117
x = √117
x = 3√13

Use the equation mg sin A = umg cos A to determine the angle at which a waxed wood block on an inclined plane of wet snow begins to slide. Assume the coefficient of friction, u, is 0.17. 9.6º 42º 48º 22º
Answers
The weight, mg, is resolved into mg cos(A) and mg sin(A).
g = 9.8 m/s², acceleration due to gravity
μ = 0.17, static coefficient of friction
For motion to be initiated,
mg sinA = μN
or
mgsin(A) = μmg cos(A)
sin(A)/cos(A) = μ
tan(A) = μ = 0.17
A = tan⁻¹ 0.17 = 9.648° = 9.6° (approx)
Answer: 9.6°
Using the friction equation mg sin A = μmg cos A and the given coefficient of friction (μ) of 0.17, the angle at which a waxed wood block begins to slide on wet snow is calculated to be approximately 9.6°.
Explanation:To find the angle at which a waxed wood block on an inclined plane of wet snow begins to slide, we can use the equation mg sin A = μmg cos A, where A is the angle of inclination, m is the mass of the block, g is the acceleration due to gravity, and μ is the coefficient of friction. Since the mass (m) and gravity (g) are both common factors on each side of the equation, they can be canceled out, leaving us with tan A = μ, where tan A is the tangent of the angle A, and μ is the coefficient of friction (0.17 in this case). Solving for A gives us A = arctan(μ). So, A = arctan(0.17), which calculates to approximately 9.6°. This is the angle at which the block begins to slide.

Two mechanics worked on a car. the first mechanic worked for 5 hours, and the second mechanic worked for 15 hours. together they charged a total of $1450 . what was the rate charged per hour by each mechanic if the sum of the two rates was $160 per hour
Answers
the second mechanic = b
the first mechanic works for 4 hours = 4 * a
the second mechanic works for 15 hours = 15 * b
total charged = t
t = 4a + 15b
sum of their rates:
a + b = 160
b = 160 - a
t = 4a + 15b
1450 = 4a + 15 * (160 - a)
1450 = 4a + 2400 - 15a
now let's make the formula easier.
15a - 4a = 2400 - 1450
11a = 950
a = 86.36
b = 160 - 86.36 = 73.64

Find the greatest common factor for the group of numbers. 12 , 28 , 24
Answers
Final answer:
The greatest common factor (GCF) of the numbers 12, 28, and 24 is found by identifying the smallest powers of their common prime factors, which are 2 and 3. Multiplying these together, 2 squared times 3, gives us the GCF of 12.
Explanation:
To find the greatest common factor (GCF) of the numbers 12, 28, and 24, we break each number down into its prime factors:
28 = 2 x 2 x 7
The smallest power of 3 that is common is just 3.
Therefore, the GCF of 12, 28 and 24 is 22 x 3 = 4 x 3 = 12.

A person died leaving behind inheritance of Rs. 300000. Distribute the amount among 4 sons and 3 daughters so that each son gets double of what a daughter gets. Find the share of each when a debt of Rs. 80,000 was also to be paid.
Answers
4s+3d=300000-80000
4s+3d=220000, now using s=2d in this equation you get:
4(2d)+3d=220000
8d+3d=220000
11d=220000
d=20000
So each daughter gets 20000 and each son gets 40000.
The inheritance problem deals with distributing Rs. 300,000 among 4 sons and 3 daughters after a Rs. 80,000 debt is paid. Using algebra and ratios, it is determined that each daughter receives Rs. 20,000 while each son receives Rs. 40,000.
The situation given is that a person dies leaving behind an inheritance of Rs. 300,000, which must be divided among 4 sons and 3 daughters such that each son receives double what each daughter gets. Additionally, a debt of Rs. 80,000 is to be taken out of the inheritance before distribution.
First, we need to consider the debt. Subtracting the debt from the total inheritance, we have:
Total inheritance after debt = Rs. 300,000 - Rs. 80,000 = Rs. 220,000
Now, let's assume each daughter gets x amount. Therefore, each son gets 2x the amount. We can set up the equation accounting for all sons and daughters:
3x (daughters' shares) + 4(2x) (sons' shares) = Rs. 220,000
Simplifying:
3x + 8x = Rs. 220,000
11x = Rs. 220,000
x = Rs. 20,000 (share of each daughter)
Consequently, the share of each son will be double that of a daughter, which is:
2x = 2(Rs. 20,000) = Rs. 40,000 (share of each son)

PLEASE HELP!!!! If a function, f(x) is shifted to the left four units, what will the transformed function look like?
Answers
So that means f(x) turns into f(x+4)
For example, say we had the function f(x) = 5x^2 + 10x
Shifting f(x) four units to the left leads to
f(x) = 5x^2 + 10x
f(x+4) = 5(x+4)^2 + 10(x+4) ... notice the replacements in bold
f(x+4) = 5(x^2+8x+16) + 10(x+4)

The graph of the function f(x) = (x² + 3x + 5 )/(x+ 2) is a parabola that is shifted to the left by 2 units.
The parabola is similar to the graph of the function y = x², but it is narrower because the denominator of the fraction is x + 2.
The graph also has a hole at the point (-2, 5), which is the point where the denominator of the fraction is 0.
