The angle of elevation of the top of a flagpole from a point on the ground 30 meters
from the base of the flagpole is 18 degrees. What is the height of the flagpole, to the
nearest meter?
I need help
Answer:
[tex]10\:\mathrm{meters}[/tex]
Step-by-step explanation:
We can use trigonometry for a right triangle to solve this problem:
[tex]\tan 18^{\circ}=\frac{h}{30},\\h=30\cdot\tan 18^{\circ},\\h\approx \fbox{$10\:\mathrm{m}$}[/tex].
The height of the flagpole is 10 meters.
What is angle of elevation?"It is the angle from the horizontal upward to an object."
For given question,
Consider the following figure.
The angle of elevation is 18°
⇒ ∠ACB = 18°
Also, BC = 30 meters
We need to find the height of the flagpole i.e., we need to find the distance AB.
Consider a tan(∠ACB )
[tex]\Rightarrow tan(18^{\circ})=\frac{AB}{BC}\\\\ \Rightarrow 0.3249 = \frac{AB}{30}\\\\ \Rightarrow AB=9.747 ~~meters\\\\\Rightarrow AB\approx 10~~meters[/tex]
Therefore, the height of the flagpole is 10 meters.

Which of the following represents a function?
Answer:
A.
Step-by-step explanation:
in order for a function to be a function, one input must only have one output.
We see that in option B, -1 has two outputs (10, 18)
In option c, we see that -4 has two outputs (2, -2)
In option D, we see that -3 has two outputs (5, 0)
This means A is the correct option because each input has only one output.
The Owner of a large chain restaurant with 1,200 employees estimates that about 250 employees will ask for winter vacation. A random sample of 40 employees show that 8 of them will ask for the time off . Determine whether the owner's estimate is likely to be accurate
Answer:
He is likely to be accurate.
Step-by-step explanation:
An estimate is a value that is close to the true or actual value. Usually, a sample from a smaller group is projected into a larger population. To crosscheck the trueness of the estimate, we compare the small sample to the large sample thus;
If 40 employees = 8 applicants for vacation
1200 employees = ? applicants for vacation
Cross multiplying the above gives;
1200 * 8
40
= 9600/40
= 240 applicants for vacation.
The figure 240 is close to the owner's estimate of 250.

1) Give an example of a rational number AND an irrational number.
What is the difference between them?
2) What is the decimal equivalent of your two examples?
3) Can every repeating decimal be written as a rational number? Explain why or why
not.
Answer:
Step-by-step explanation:
A rational number is one that can be expressed as a fraction. Pi cannot be. If I tell you that the 2000th digit of pi is an 8 (which it probably isn't) and I ask you to tell me the 2001 value of pi, you have no better odds that 1/10 of getting it right.
A rational number can always be reduced to a fraction. 20 1/2 can be expressed as a fraction. It is 20.5
Pi is irrational. I don't know the value of pi beyond what a calculator can tell me. 3.14159265 The next digit is a 4. I know this only because that is what the calculator tells me.
Repeating decimals call always be represented as a fraction. For ex
x = 0.123123123123123
1000x = 123.123123123123
x = .123123123123123 Subtract
999x = 123
This comes about because in both cases what is after the decimal is the same.
x = 123/999 = 41/333

Answer:
135c^7
Step-by-step explanation:
[tex]135c^7[/tex] is the simplified equation of the given expression.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
To simplify [tex]5c(3c^2)^3[/tex], we need to apply the power rule of exponents, which states that [tex](a^m)^n = a^{(m*n)[/tex].
In this case, we have [tex](3c^2)^3[/tex], which means we need to multiply the exponent 3 by the exponent 2, giving us 6. So, we can rewrite the expression as:
[tex]5c(3c^2)^3 = 5c(3^3c^{(2*3)})[/tex]
Simplifying further, we get:
[tex]5c(3^3c^6) = 5c(27c^6)[/tex]
Finally, we can simplify by multiplying 5 and 27, and adding the exponents of c:
[tex]5c(27c^6) = 135c^{(1+6)} = 135c^7[/tex]
Therefore, [tex]5c(3c^2)^3[/tex] simplifies to [tex]135c^7[/tex].

Find the measure of the numbered angle
Answer:
1 = 50°, 2 = 130°, 3 = 50°, 4 = 130°, 5 = 40°, 6 = 140°, 7 = 90°, 8 = 140°
Step-by-step explanation:
The sum of the angles of a triangle is 180°. A flat angle measures 180° as well.
Angle 1: 180 - 90 - 40 = 50°
Angle 2: 180 - 50 = 130°
Angle 3: 180 - 130 = 50°
Angle 4: 180 - 50 = 130°
Angle 5: 180 - 90 - 50 = 40°
Angle 6: 180 - 40 = 140°
Angle 7: 180 - 90 = 90°
Angle 8: 180 - 40 = 140°

In a study of facial behavior, people in a control group are timed for eye contact in a 5- minute period. Their times are normally distributed with a mean of 184 seconds and a standard deviation of 55 seconds. For a randomly selected person from the control group, find the probability that the eye contact time is greater than 230 seconds
Answer:
0.20148
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 230
μ is the population mean = 184
σ is the population standard deviation = 55
z = 230 - 184/55
z = 0.83636
P-value from Z-Table:
P(x<230) = 0.79852
P(x>230) = 1 - P(x<230) = 0.20148
Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148

Answer/Step-by-step explanation:
Area of trapezium = ½*(AD + BC)*AB
Area = 42 cm²
AD = (x + 8) cm
BC = (x + 5) cm
AB = x cm
Plug in the values into the equation
42 = ½((x + 8) + (x + 5))*x
42 = ½((x + 8 + x + 5)*x
42 = ½(2x + 13)*x
Multiply both sides by 2
42*2 = (2x + 13)*x
84 = 2x² + 13x
2x² + 13x = 84
Subtract both sides by 84
2x² + 13x - 84 = 0

Hadley was going out with her friends for dinner. The equation c = x + 0.07x + 0.18x gives the total cost c of her meal, where x is the cost before tax and tip. The restaurant charges 7% sales tax and she plans to leave an 18% tip. She knew that she can only spend $18. What is the maximum amount Hadley can spend before tax and tip?
Answer:
$14.4
Step-by-step
c = x + 0.07x + 0.18x
18 = x + 0.07x + 0.18x
18 = 1.25x (simplify)
14.4 = x (divide both sides by 1.25)
Aden gets paid daily for the work she does and she does not work on Sundays. Last year which was n ot a leap year had 52 Sundays. She got Dhs 354003 as her annual salary last year. If the March of last year had 5 Sundays, how much did she earn in that month?
Answer: Dhs 29312.4
Step-by-step explanation:
For a leap year, we should note that there are 366 days. Since there were 52 Sundays, the number of days worked by Aden will be:
= 366 - 52
= 314 days
Since she got Dhs 354003 as her annual salary last year, the amount received per day will be:
= 354003 / 314
= Dhs 1127.4
The amount earned in March will be:
= (31 - 5) × 1127.4
= 26 × 1127.4
= Dhs 29312.4

X = ?
Answer:
80.4
Step-by-step explanation:
Use the tan formula
The value of X is approximately 80.38 units.
Here, we have,
To find the value of X, we can use trigonometric functions.
In this case, we'll use the tangent function, which relates the angle and the sides of a right triangle.
The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
In this scenario, we have the angle between the hypotenuse and the base as 15°, and the base of the triangle is given as 300 units.
Using the tangent function, we can set up the equation:
tan(15°) = X / 300
Now, let's solve for X:
X = 300 * tan(15°)
Using a calculator, we find:
X ≈ 80.384
Rounding to the nearest tenth, the value of X is approximately 80.38 units.
