To find the height of a pole, a surveyor moves 150 feet away from the base of the pole and then, with a transit 4 feet tall, measures the angle of elevation to the top of the pole to be 42°. To the nearest foot, what is the height of the pole?
Answer: The answer is 139 feet
H = height of the pole =?
BC = ED = height of the transit = 4 ft
CD = BE = distance moved away from the base of the pole = 140 ft
Consider the ΔABE
tan44 = AE/BE
tan44 = h/140
h = 140 tan44
h = 135.2 ft
H = height of pole = AE + ED = h + ED = 135.2 + 4
H = 139.2 ft

Answer: This question does not make sense since 2 minus 4 is -2 and 7 > -2, which means this inequality is true by itself. There are no "solutions" to this inequality since there are no variables. Maybe you made a typo?
Edit: I found the actual question on the internet (it's 7 > z - 4) and the answers are 6, 7, and 10.

Step-by-step explanation:
we take sin the angle on the length of the side that opposite to it ...
The value of x from the triangle is x = 10.6
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ABC
Now , the measure of hypotenuse of the triangle = 15
Let the angle be θ = 45°
From the trigonometric relations ,
sin θ = opposite / hypotenuse
On simplifying the equation , we get
sin 45° = x / 15
where sin 45° = 0.7071
So , the value of x = 0.7071 x 15
The value of x = 10.6
Hence , the value of x from the triangle is x = 10.6

Based on the model in part (c), is the amount of unspoiled grain in the silo increasing or decreasing at time t = 6? Show the work that leads to your answer. =
Hi there!
a)
We can approximate g'(3) by finding the slope of g(t) over an interval containing t = 3.
We can use the endpoints t = 1 and t = 5 min for the best estimate.
[tex]slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{20.5-15.1}{5-1} = \boxed{1.35 \frac{ft^3}{min^2}}[/tex]
This means that the rate of grain being added to the silo is INCREASING at a rate of 1.35 ft³/min². (Or in other words, the grain is being poured at an increasingly greater rate)
b)
The total amount of grain added is the integral of g(t), so:
[tex]\text{total amount of grain} = \int\limits^8_0 {g(t)} \, dt[/tex]
We can do a right riemann sum by using the right endpoints (t = 1, t = 5, t = 6, t = 8) to calculate.
Riemann sums are essentially rectangles added up to calculate an approximate value for the area under a curve.
The bases are the spaces between each value in the chart, while the heights are the values of g(t).
Using the intervals and values in the chart:
[tex]1(15.1) + 4(20.5) + 1(18.3) + 2(22.7) = \boxed{160.8 ft^3}[/tex]
c)
We can subtract the two integrals to find the total amount of unspoiled grain.
With g(t) being fresh grain and w(t) being spoiled grain, let y(t) represent unspoiled grain.
[tex]y(t) = \int\limits^8_0 {g(t)} \, dt - \int\limits^8_0 {w(t)} \, dt[/tex]
Use a calculator to evaluate:
[tex]y(t) = 160.8 - \int\limits^8_0 {w(t)} \, dt = 160.8 - 99.05 = \boxed{61.749 ft^3}[/tex]
d)
We can do the first derivative test to determine whether the amount of grain is increasing or decreasing. (Whether the first derivative is positive or negative at this value).
For the above integral, we know that the derivative is:
[tex]y'(t) = g(t) - w(t)[/tex]
Plug in the values for t = 6:
[tex]w(6) = 32 \cdot \sqrt{sin(\frac{\pi (6)}{74})} = 16.06[/tex]
[tex]y'(6) = g(6) - w(6) = 18.3 - 16.06 = 2.23 \frac{ft^3}{min}[/tex]
This value is POSITIVE, so the amount of unspoiled grain is INCREASING.

A music-streaming service charges $9 per month for a single user. Additional users within the same household can be added for $3 per month. Write an equation that shows how the monthly cost, y, depends on the number of additional users in the household, X. Do not include dollar signs in the equation. y=
The equation that shows the monthly cost is y = 9 + 3x
What is the equation that represents the monthly cost?
The monthly cost is a function of the charge for a single user and the cost of additional users. The monthly cost increases with the number of additional users.
The charge for a single user can be considered a fixed cost since it remains constant while the cost of the additional user can be considered a variable cost since it increases with the number of users.

A slot machine has 3 dials. Each dial has 40 positions, two of which are "Jackpot." To win the jackpot, all three dials must be in the "Jackpot" position. Assuming each play spins the dials and stops each independently and randomly, what are the odds of one play winning the jackpot?
Answer: there is a 1.2% of winning
Step-by-step explanation: there is a 1.2% chance of winning.
Step-by-step explanation:
The odds of one player that wins the jackpot should be 0.00156%.
Given that,
There are 3 dials.
In each dial, there are 40 positions.
So, the probability of receiving the jackpot should be \frac{1}{40}
40

Now the odds of one player that wins the jackpot should be
\begin{gathered}= \frac{1}{40} \times \frac{1}{40} \times \frac{1}{40} \\\\\end{gathered}
=

It takes 56 pounds of seed to completely plant an 8-acre field. How many acres can be planted per pound of seed?
Answer:
7
Step-by-step explanation:
8 divided by 56 equals 7
Answer:
1/7 acre
Step-by-step explanation:
The number of acres planted is presumed to be proportional to the number of pounds of seeds:
acres/pounds = 8/56 = x/1
x = 1×8/56 = 1/7
1/7 acre can be planted per pound of seed.
_____
Additional comment
When you recognize that 56 = 8×7, there is a tendency to want to divide 56 by 8. That would result in the unit rate ...
(56 lb)/(8 ac) = 7 lb/ac
That is, it takes 7 pounds of seed to plant 1 acre. The question asks how many acres can be planted with 1 pound. Clearly, that is 1/7 of the amount of seed required for 1 acre, so 1 pound will plant 1/7 acre.
Decompose 3p-1/p^2-1 into partial functions
(please select from the choices)
Answer:
a)
Step-by-step explanation:
[tex]\dfrac{3p-1}{p^2-1}[/tex]
Factorize the denominator:
[tex]\implies \dfrac{3p-1}{(p+1)(p-1)}[/tex]
Therefore,
[tex]\implies \dfrac{3p-1}{(p+1)(p-1)}=\dfrac{A}{p+1}+\dfrac{B}{p-1}[/tex]
[tex]\implies 3p-1=A(p-1)}+B(p+1)[/tex]
When p = 1:
[tex]\implies 2=A(0)}+B(2)[/tex]
[tex]\implies B=1[/tex]
When p = -1:
[tex]\implies -4=A(-2)}+B(0)[/tex]

a glass fish tank in the shape of a rectangular prism has a base that measures 22 inches by 12 inches. If the tank can hold a maximum of 3,960 cubic inches of water, how much glass was used to construct the tank?
Answer:
582.76 square inches of glass is required to construct the tank.
Step-by-step explanation:
Base dimension = 22×12 inches
volume of fish tank =3960 cubic inches
volume= l×b×h
3960=22×12×h
h=3960/(22×12)
h=3960/462
h=8.57 inches
the glass used=lateral surface area of a rectangular prism

(c) What is Euclid’s weight?
(d) Jake adopts a third dog, Riemann. Riemann weighs exactly twice what Euclid weighs. The combined weight of the three dogs is pounds. What is Riemann’s weight, and what is Pythagoras’s weight? Show your work.
Answer:The weight of Euclid is 10.625 pounds, and the weight of Riemann is 21.25 pounds.
Let the current weight of Euclid = x
Let the current weight of Pythagoras = T
Let the January weight of Pythagoras = y
The expression that represents the given scenario is written as;
when Pythagoras lost 13 pounds: T = y - 13
when Pythagoras gains 1.2 times Euclid's weight: = T + 1.2x
when Pythagoras weight is 1/4 pound less than weight in January:
T + 1.2x + 0.25 = y
y- 13 + 1.2x + 0.25 = y
1.2x - 12.75 = 0
Euclid's weight is calculated as follows;
1.2x = 12.75
The weight of Riemann is calculated as follows;
