The distance from the plane to the building is _________ meters.
Answers
Answer:
The distance from the plane to the building is ___2553.2___meters.
Step-by-step explanation:
Given that An airplane is at an altitude of 1200 m.
The angle of depression to a building at the airport on the ground measures 28°.
We need to find the distance from the plane to the building.
Please check the attached diagram.
Let 'x' be the required distance in meters.
It forms a right-angled triangle as shown in the attached diagram.
The angle = Ф = 28°
The opposite to angle = 1200 meters
All we need to find the hypotenuse to determine the distance from the plane to the building.
Using the trigonometric ratio
sin θ = Perpendicular ÷ Hypotenuse
sin (28°) = 1200 ÷ x
x = 1200/sin (28°)
= 1200 / 0.47 ∵ sin (28°) = 0.47
= 2553.2 m
Thus, the distance from the plane to the building is ___2553.2___meters.

a semigroup which has a left identity element and in which every element has a right inverse is a group
Answers
Element and in which every element has a right inverse is a group?
Now, If both the identity and the inverse are of the same side, this is simple. For, instead of the above, say every element has a left inverse. For a∈G denote this left inverse by a−1.
Then(aa−1)(aa−1)=a(a−1a)a−1=aa−1
and we can use the fact that
cc=c
⟹c=1
to get that inverses are in fact two-sided: aa−1=1
From which it follows that
a=1⋅
a=(aa−1)a=a(a−1a)=a⋅
1 as desired. But in the scenario given we cannot use cc=c⟹c=1, and I can see no other way to prove this.

this book is presently being used at xgnu university. the area of the cover of this book is 72.5 square krylls. what is its area in square blims?"" excerpt from: steven s. zumdahl. ""introductory chemistry: a foundation."" ibooks.
Answers
Converting the book's cover area from 72.5 square krylls to square blims is 0.051785 square blims.
What is the conversion rate?The conversion rate refers to the rate of change of a unit of measurement to another unit.
For example, the conversion rate for 100 centimeters equals 1 meter.
To convert the higher unit to a smaller unit, we divide.
Data and Calculations:Given that 1400 kryll = 1 blim
Area of the book's cover = 72.5 square krylls
The area in square blims = 0.051785 square blims (72.5/1,400).
Thus, the converted area of the book's cover from 72.5 square krylls to square blims is 0.051785 square blims.

so from 3 to 6 it was a + 3 from 6 to 11 it was a+5 from 11 to 18 it was a + 7.
if you look carefully,2,3 and 7 are odd numbers meaning that the next pattern should be an odd number (9) which will be added to the numbers at the top.
you can still say that they were increasing by 2. (3 to 5 to 7)
so you can add 2 to 7 to get a nine. then,add 9 to 18 to get a 27.

Jamie is training for race and runs a 9 minute mile. She has cut a total 39 seconds off her time over the past 6 months. The situation can represented by the expression- 39 divided by 6. On average, how much time she cut off of her mile each month? Find the solution and explain what it means in the context of the problem.
Answers
1) On average, the time Jamie cut off her mile each month is 6.5 seconds.
2) In this context, the 6.5 seconds that Jamie cut off her mile each month means that she can finish a 9-minute-mile race by less than 6.5 seconds.
How is the average cut-off time determined?The average cut-off time per month is determined by the mathematical operation of division.
Average refers to the mean of a data set divided by the number in the data set.
Data and Calculations:The race Jamie is training for = a 9-minute mile
Cut-off time achieved in 6 months = 39 seconds
Period of training = 6 months
Average cut-off time = 6.5 seconds (39/6)
Time Jamie can finish the race = 8 minutes and 53.5 seconds (9 minutes - 6.5 seconds)
Thus, Jamie can complete the race in 8 minutes and 53.5 seconds if she maintains the average.

Function transformation involves changing the form of a function.
The equation of the translated function is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
The parent function is given as:
[tex]f(x) = \sqrt[3]{x}[/tex]
First, the function is shifted left by 6 units.
The rule of this translation is:
[tex](x,y) \to (x + 6,y)[/tex]
So, we have:
[tex]f(x) = \sqrt[3]{x + 6}[/tex]
Next, the function is shifted up by 1 unit.
The rule of this translation is:
[tex](x,y) \to (x,y+1)[/tex]
So, we have:
[tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
Hence, the equation of the translated function is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]

what is Absolute value function?A function that wraps an algebraic expression in absolute value symbols is known as an absolute value function. Remember that a number's distance from 0 on the number line represents its absolute value.
According to the given information:The vertex of the function y = |x + 1| + 3
The function is given as:
y = |x + 1| + 3
The above function is an absolute value function
An absolute value function is represented as:

Because a few extreme scores can create a deceptively large estimate of variation, the (B) range offers only a crude estimate of the variation in a data set.
What is a range?The range of a set of numbers is the difference between the highest and lowest values. Subtract the smallest number from the largest number in the set to calculate the range. To calculate the range, find the maximum observed value of a variable and subtract the minimum observed value (the minimum). The range only considers these two values and ignores the data points between the distribution's two extremes.Because a few extreme scores can produce an erroneously large estimate of variation, the range provides only a rough estimate of the variation in a data set.Therefore, because a few extreme scores can create a deceptively large estimate of variation, the (B) range offers only a crude estimate of the variation in a data set.
