Answer:
31 m
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
With reference to the attached diagram, we have ...
tan(49°) = BG/GP
BG = GP×tan(49°) = (27 m)×tan(49°) ≈ 31.0599 m
The height of the building is about 31 meters.
There is a rectangular garden with an area of 24 square leel. The garden is 2 feet longer than it is wide. Create an equation that can be used to determine the length and wath of the garden
Answers
The equation that can be used to determine the length and width of the garden is x² + 2x - 24 =0, the length is 6 feet and the width is 4 feet.
There is a rectangular garden with an area of 24 square feet
The garden is 2 feet longer than it is wide
Let the width of the garden be x
Then, the length of the garden is x + 2
The area of a rectangular garden = length of the garden x width of the garden
24 = x (x + 2)
x² + 2x - 24 =0
x² + 6x - 4x - 24 = 0
x(x + 6) -4(x + 6) = 0
(x - 4)(x + 6) = 0
x - 4 = 0
x = 4
Width of the rectangular garden is 4 feet
Length of the rectangular garden is (4 + 2) feet = 6feet
Therefore, the equation that can be used to determine the length and width of the garden is x² + 2x - 24 =0, the length is 6 feet and the width is 4 feet.

I think of two consecutive odd numbers, five times the smaller plus three times the larger is 62. Find the numbers.
Answers
Answer:
7 and 9
Step-by-step explanation:
Variables:
x = smaller number
y = larger number
We can set up two equations with the information given:
5x + 3y = 62
and
y = x + 2
We get the second equation with the information that the two numbers are consecutive and both odd. therefore the smaller number is two less than the larger number, and the larger number is two greater than the smaller number.
Next, we need to replace our y in the first equation with the y in the second:
5x + 3y = 62
5x + 3 (x+2) = 62
5x + 3x + 6 = 62
8x = 56
x (smaller number) = 7
Finally, we solve for the larger number by placing it back into the second equation:
y = x + 2
y = 7 + 2
y (larger number) = 9

The average birth weight of elephants is 200 pounds. Assume that the distribution of birth weights is Normal with a standard deviation of 60 pounds. Find the birth weight of elephants at the 85th percentile.
The birth weight of elephants at the 85th percentile is __ pounds
(round to the nearest integer as needed)
Answers
The birth weight of elephants at the 85th percentile is 262.16 pounds
What is the standard deviation?Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Given that:-
The average birth weight of elephants is 200 pounds \(\mu\) = 200
The deviation of 60 pounds. \(\sigma\) = 60
The birth weight of elephants at the 85th percentile. z = 85%= 1.036
Now from the formula of z-score:-
\(z=\dfrac{x-\mu}{\sigma}\\\\\\z=\dfrac{x-200}{60}\\\\\\1.036\times 60=x-200\\\\\\x=\ \ 262.16\ pounds\)
Hence the birth weight of elephants at the 85th percentile is 262.16 pounds

work out the circumferrence of this circle 14cm diameter give your answer in terms of pi and state its units
Answers
Answer:
Step-by-step explanation:
The circumference of a circle is given by the formula:
C = πd
where d is the diameter of the circle. In this case, the diameter is given as 14 cm, so we can substitute that into the formula:
C = π(14 cm)
Multiplying, we get:
C = 14π cm
So the circumference of the circle is 14π cm. The units are centimeters, since circumference is a length measurement.

The angle of elevation from a point on the ground to the top of a tower is 18°. The base of the tower is 100 feet from the point on the ground. Find the height of the tower. Round to the nearest tenth of a foot.
Answers
Answer:
32.5 feet
Step-by-step explanation:
This situation forms a right triangle. We are given the distance from the base of the tower (long leg of the triangle) and are asked to find the height (short leg of the triangle).
With this information, we can use the tan ratio, opposite over adjacent, to find the height of the tower.
tan 18 = \(\frac{x}{100}\)
Multiply each side by 100:
(100) tan 18 = x
Simplify and round to the nearest tenth:
32.49 = x
32.5 = x
So, the height of the tower is approximately 32.5 feet

Determine the domain of the function F(x) =2-x/12x^2+8x
Answers
The domain of a function is the set of all possible values of x for which the function is defined. In this case, the function is defined for all values of x except those that make the denominator equal to zero, since division by zero is undefined.
So, to find the domain of the function, we need to find the values of x that make the denominator equal to zero and exclude them from the domain.
12x^2+8x = 0
4x(3x + 2) = 0
x = 0 or x = -2/3
Therefore, the domain of the function F(x) is all real numbers except 0 and -2/3. In interval notation, we can write the domain as:
(-∞, -2/3) U (-2/3, 0) U (0, ∞)

Sixty men can build a wall in 40days but though they begin the work together, 55 men quit every ten days. The Time needed to build the wall is?
Answers
It would take 370 days to build the wall with the given conditions.
If 60 men can build a wall in 40 days, then the total man-days required to build the wall is:
60 men x 40 days = 2400 man-days
However, 55 men quit every ten days, which means that after 10 days, there are only 60 - 55 = 5 men left to work on the wall. After 20 days, there are only 5 - 55 = -50 men left, which means that the remaining 5 men cannot work any faster than they were already working. Therefore, we can assume that the remaining 5 men complete the wall on their own.
The number of man-days required for the first 10 days is:
60 men x 10 days = 600 man-days
The number of man-days required for the second 10 days is:
5 men x 10 days = 50 man-days
The total number of man-days required for the first 20 days is:
600 man-days + 50 man-days = 650 man-days
The remaining work can be completed by the 5 men in:
2400 man-days - 650 man-days = 1750 man-days
Therefore, the total time needed to build the wall is:
20 days + 1750 man-days / 5 men = 20 + 350 days = 370 days

Below is the graph of equation y = -|x − 2 | +2. Use this graph to find all values of x
for the given values of y
Answers
If y = 3, we can see that there are again two values of x that satisfy the equation: x = 0 and x = 4. This is because the graph intersects the horizontal line at y = 3 at two points.
What is equation of graph?A mathematical statement used to describe the relationship between the variables that make up a graph is called an equation.
To put it another way, a graph equation is a formula that can be applied to either build the graph or identify certain points on the graph.
Using the graph of the equation y = -|x - 2| + 2, we can find all the values of x for a given value of y by looking at where the graph intersects the horizontal line at y.
For example, if y = 1, we can see from the graph that there are two values of x that satisfy the equation: x = 3 and x = 1. This is because the graph intersects the horizontal line at y = 1 at two points.
If y = 2, we can see that there is only one value of x that satisfies the equation: x = 2. This is because the vertex of the absolute value function is at (2, 2), and the graph is reflected below the x-axis, so it only intersects the horizontal line at y = 2 at one point.
We can repeat this process for any value of y to find the corresponding values of x that satisfy the equation.

We want to find the area of the rectangular field.
The area of a rectangle is given by:
\(A=L*W\)where L = length
W = width
To find the area of the field in square meters, we first have to convert its length and width from kilometers to meters as follows:
\(\begin{gathered} 1km=1000m \\ \\ 0.45km=0.45*1000=450m \\ \\ 0.3km=0.3*1000=300m \end{gathered}\)Therefore, the area of the rectangular field is:
