Step-by-step explanation:
A ship is anchored off a long straight shoreline that runs north and south. From two observation points
miles apart on shore, the bearings of the ship are
and
. What is the distance from the ship to each of the observation points? Round each answer to the nearest tenth of a mile.
The distance from the north most ship to the observation is
miles.
The distance from the south most ship to the observation is
miles.
The distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.
The bearing is defined as the angle measured clockwise from the north direction. A ship is anchored off a long straight shoreline that runs north and south.
From two observation points miles apart on shore, the bearings of the ship are 52 degrees and 134 degrees respectively. To find the distance from the ship to each of the observation points, we can use trigonometry.
Let's call the distance from the north observation point to the ship x, and the distance from the south observation point to the ship y. The bearings from the north and south observation points can be drawn as follows:
[asy]
unitsize(1cm);
pair O = (0,0), N = (-2,0), S = (2,0), A = (-2,1), B = (2,-1);
draw(O--N--A,Arrow);
draw(O--S--B,Arrow);
\(label("$52^\circ$", N + 0.3*dir(52), NE);\)
\(label("$134^\circ$", S + 0.3*dir(134), SE);\)
draw(O--A--B--cycle,dashed);
\(label("$x$", (N+A)/2, W);\)
\(label("$y$", (S+B)/2, E);\)
[/asy]
We can use the tangent function to find x and y, since we have the angle and opposite side.
From the north observation point, we have:
\($$\tan(52^\circ) = \frac{x}{2}$$$$x = 2\tan(52^\circ) \approx 2.95$$\)
From the south observation point, we have:
\($$\tan(134^\circ) = \frac{y}{2}$$$$y = 2\tan(134^\circ) \approx 9.88$$\)
Therefore, the distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.

What is the total surface area
Answer:
Step-by-step explanation:
4tan(x)-7=0 for 0<=x<360
Answer:
x = 65.26 degrees or x = 245.26 degrees.
Step-by-step explanation:
To solve the equation 4tan(x)-7=0 for 0<=x<360, we can first isolate the tangent term by adding 7 to both sides:
4tan(x) = 7
Then, we can divide both sides by 4 to get:
tan(x) = 7/4
Now, we need to find the values of x that satisfy this equation. We can use the inverse tangent function (also known as arctan or tan^-1) to do this. Taking the inverse tangent of both sides, we get:
x = tan^-1(7/4)
Using a calculator or a table of trigonometric values, we can find the value of arctan(7/4) to be approximately 65.26 degrees (remember to use the appropriate units, either degrees or radians).
However, we need to be careful here, because the tangent function has a period of 180 degrees (or pi radians), which means that it repeats every 180 degrees. Therefore, there are actually two solutions to this equation in the given domain of 0<=x<360: one in the first quadrant (0 to 90 degrees) and one in the third quadrant (180 to 270 degrees).
To find the solution in the first quadrant, we can simply use the value we just calculated:
x = 65.26 degrees (rounded to two decimal places)
To find the solution in the third quadrant, we can add 180 degrees to the first quadrant solution:
x = 65.26 + 180 = 245.26 degrees (rounded to two decimal places)
So the solutions to the equation 4tan(x)-7=0 for 0<=x<360 are:
x = 65.26 degrees or x = 245.26 degrees.

A man’s eye level is 1.7m above horizontal ground and 13m from a vertical pole. If the pole is 3.8 m high calculate the nearest degree, the angle of elevation of the pole from his eyes
The angle of elevation of the pole from the man's eyes is about 9.2°
What is an angle of elevation?The angle of elevation from a point to an elevated location is the angle made by the line from the location to the point and the horizontal line from the point.
The elevation of a man's eye above the horizontal ground = 1.7 m
The (horizontal) distance of the man's eye from the vertical pole = 13 m
The height of the pole = 3.8 m
The angle of elevation of the top of the pole from the man's eye can be found as follows;
The vertical height from the man's eye to the top of the pole = 3.8 m - 1.7 m = 2.1 m
Let θ represent the angle of elevation of the top of the pole to the man's eye, from the trigonometric ratio of tangent, we get;

Solve the system of equations using substitution.
4x + 2y = 6
x = 2y + 4
(1, 1)
(2,-1)
(8,2)
(10,3)
Answer:
(2,-1)
Step-by-step explanation:
We can use substitution to solve this system of equations. Since x is already solved for in the second equation, we can substitute 2y + 4 for x in the first equation:
4(2y + 4) + 2y = 6
Simplifying the left side:
8y + 16 + 2y = 6
Combining like terms:
10y + 16 = 6
Subtracting 16 from both sides:
10y = -10
Dividing both sides by 10:
y = -1
Now that we know y, we can use the second equation to find x:
x = 2y + 4
x = 2(-1) + 4
x = 2
Therefore, the solution to the system of equations is (x, y) = (2, -1).
The correct answer choice is (2, -1).
If 15% of the customers total is $98,880, then the sum total equals what
The sum total by the given data is equals to $658,880.
We are given that;
Percent=15%
Amount= $98,880
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
To divide by a percentage, we can convert it to a decimal by moving the decimal point two places to the left. This gives us:
15% = 0.15
To divide by 0.15, we can multiply by its reciprocal, which is 1/0.15. This gives us:
$98,880 / 0.15 = $98,880 x 1/0.15
To multiply by 100, we can move the decimal point two places to the right. This gives us:
$98,880 x 1/0.15 x 100 = $658,880

How do you do b and c?
Answer:
b) 18

Step-by-step explanation:
While we can solve this equation with separation of variables, it isn't necessary. The coffee is originally at 95°, and the ambient temperature is 18°. The top right graph is the only one that shows this trend.
As t approaches infinity, y approaches the ambient temperature of 18°.
yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)
yₙ₊₁ = yₙ + 2 (-0.02 (yₙ − 18))
yₙ₊₁ = yₙ − 0.04 (yₙ − 18)
yₙ₊₁ = 0.96 yₙ + 0.72
When n=0:
y₁ = 0.96 y₀ + 0.72
y₁ = 0.96 (95) + 0.72
y₁ = 91.92
When n=1:
y₂ = 0.96 y₁ + 0.72
y₂ = 0.96 (91.92) + 0.72
y₂ = 88.96
When n=2:
y₃ = 0.96 y₂ + 0.72
y₃ = 0.96 (88.96) + 0.72
y₃ = 86.12
When n=3:

y₄ = 0.96 (86.12) + 0.72
y₄ = 83.40

A dairy farmer wants to mix a 75% protein supplement and a standard 30% protein ration to make 1200 pounds of a high-grade 45% protein ration. How many pounds of each should he use?
The dairy farmer should use 400 pounds of the 75% protein supplement and 800 pounds of the 30% protein ration to make 1200 pounds of a high-grade 45% protein ration.
To determine how many pounds of each protein supplement the dairy farmer should use, we can set up a system of equations based on the given information.
Let's denote the following:
x = pounds of the 75% protein supplement
y = pounds of the 30% protein ration
The total weight of the mixture is 1200 pounds, so we have the equation:
x + y = 1200
The protein content in the mixture should be 45% of the total weight, so we have the equation:
0.75x + 0.30y = 0.45 * 1200
Now we can solve this system of equations.
First, let's rewrite the second equation in decimal form:
0.75x + 0.30y = 540
To make it easier to work with, we can eliminate the decimals by multiplying both sides of the equation by 100:
75x + 30y = 54000
Now we have a system of equations:
x + y = 1200
75x + 30y = 54000
We can solve this system using any appropriate method, such as substitution or elimination. In this case, let's use the substitution method:
Solve the first equation for x:
x = 1200 - y
Substitute the value of x into the second equation:
75(1200 - y) + 30y = 54000
Simplify and solve for y:
90000 - 75y + 30y = 54000
-45y = -36000
y = 800
Now we can substitute the value of y back into the first equation to find x:
x + 800 = 1200
x = 1200 - 800
x = 400

Step-by-step explanation:
if you have a fraction with an exponent do you distribute the exponent to the denominator and the numerator
Yes, you would distribute the exponent to both the denominator and numerator. For example, if you had an expression like (2/3)^4, you would distribute the exponent to end up with (2^4)/(3^4).
For example, if you have an expression like (2/3)^4, the exponent of 4 should be distributed to both the numerator and denominator, resulting in (2^4)/(3^4). This is equivalent to multiplying the numerator and denominator by the same amount, 4 times. This is the same as writing (2*2*2*2)/(3*3*3*3), or simply
16/81.
1. Start with the expression

An 8-sided number cube is rolled 4000 times. The number 2 appeared 200 times. Determine the theoretical and experimental probability of rolling a 2 in order to determine the fairness of the number cube. Drag values or words to the boxes to correctly complete the statements.
Theoretical Probability of rolling a 2= 1/20
Experimental Probability of rolling a 2 = 1/20
Theoretical probability of rolling a 2:
The theoretical probability of an event is the ratio of the number of favourable outcomes to the total number of possible outcomes. Since there are 8 sides to the cube, the total number of possible outcomes is 8. Since the number 2 appeared 200 times out of 4000 rolls, the number of favorable outcomes is 200. Therefore, the theoretical probability of rolling a 2 is:
Theoretical Probability of rolling a 2 = Number of favourable outcomes / Total number of possible outcomes = 200/4000 = 1/20
Experimental probability of rolling a 2:
The experimental probability of an event is the ratio of the number of times the event occurred to the total number of trials. In this case, the event is rolling a 2, which occurred 200 times out of 4000 rolls.
Therefore, the experimental probability of rolling a 2 is:
Experimental Probability of rolling a 2 = Number of times the event occurred / Total number of trials = 200/4000 = 1/20
Comparing theoretical and experimental probability:
If the cube is fair, we would expect the theoretical probability and the experimental probability to be similar. In this case, both probabilities are 1/20, which means that the cube appears to be fair. However, we would need to conduct more trials to be more confident in our conclusion.
