(round your answer to the nearest foot.)
The height of the building = 1026.328ft
Given the angle of elevation = 11°
The angle of elevation is the angle formed between the horizontal distance to the base of the building and the line of sight to the top of the building.
We know that tan x = opposite side/adjacent side.
Here the opposite side gives the height of the building and the adjacent side is the distance to the base of the building on the ground.
Distance to the base of the building on the ground = 1 mile = 5280 ft.
So tan 11° = h/5280
⇒ h= tan 11° x 5280 = 0.194 x 5280 = 1026.328 ft
So the height of the building = 1026.328 ft

for a given non-zero vector v in r 3 there is a unique unit vector parallel to it. is it true or false? explain your answer.
The given statement is true that for a given non-zero vector v in r³ there is a unique unit vector parallel to it.
A vector is defined by its length and direction. If two vectors have the same direction, they are parallel. The length is irrelevant.If the length of a vector is one, it is a unit vector. The direction is irrelevant.So, in order to locate a unit vector parallel to another vector, it must point in the same direction and be of length 1.For a given non-zero vector, there are an infinite number of parallel vectors to it but with different magnitudes. There is only one vector which is not only parallel to the given non-zero vector but also has a magnitude of 1, i.e., the unit vector parallel to it.Thus, it is true that for a given non-zero vector v in r³ there is a unique unit vector parallel to it.To learn more about vectors, visit :

the length of a rectangle is four less than twice it’s width. If the width is 6 inches what is the length of the rectangle ?
Answer:
The question states four less than twice its width so we first find twice the width. The width is 6 and twice that is 12. Note that it says four less than, so four less than 12 is 8. so the length of the triangle is 8.

juan rolls a fair regular octahedral die marked with the numbers $1$ through $8$. then amal rolls a fair six-sided die. what is the probability that the product of the two rolls is a multiple of $3$?
The probability that the product of the two rolls is a multiple of 3 is 1/2.
Probability:
Probability mean the fraction of the possibility of the required event.
The formula for the probability is
P(E) = n(E)/n(S)
Where
P(E) = Probability of the event
n(E) = number of required event
n(S) = Total number of event
Given,
Juan rolls a fair regular octahedral die marked with the numbers 1 through 8.
Then Amal rolls a fair six-sided die.
Here we need to find the probability that the product of the two rolls is a multiple of 3.
We know that,
On both dice, only the faces with the numbers 3,6 are divisible by 3.
Let
P(a) = 2/8
P(a) = 1/4
it is the probability that Juan rolls a 3 or a 6,
and Similarly,
P(b) = 2/6
P(b) = 1/3
Is the probability of Amal does.
By the Principle of Inclusion-Exclusion,
[tex]\[P(a \cup b) = P(a) + P(b) - P(a \cap b) = \frac{1}{4} + \frac{1}{3} - \frac{1}{4} \cdot \frac{1}{3} = \frac{1}{2} \Rightarrow \mathrm{(C)}\][/tex]
Thus the total probability is 1/2.

What is rounded numbers?A rounded number is less precise but roughly equal to the original number in value.
To the closest hundred, 341 is equivalent to 300. This is due to the fact that 341 is more similar in value to 300 than to 400. Because $1.89 is closer to $2.00 than to $1.00, when rounded off to the nearest dollar, it becomes $2.00.
The standard rounding rule is as follows:
Round up if the number you are rounding is followed by a 5, 6, 7, 8, or 9. For instance, 38 rounded up to the nearest ten is 40.Round down if the number you are rounding is followed by a 0, 1, 2, 3, or 4. Example: 30 when 33 is rounded to the nearest ten.Learn more about rounded number

Answer:
x² + y² = z²
Step-by-step explanation:
(a)
Using the right triangle altitude theorem,
x/z = p/x
x² = pz
(b)
y/z = q/y
y² = qz
(c)
x² + y² = pz + qz
x² + y² = z(p + q)
z = p + q
x² + y² = z × z
x² + y² = z²
Write the equation of the line in slope-intercept form that passes through the points (5,3) and (1,−5).
Answer:
y = −2x + 8
Step-by-step explanation:
y = −2x + 8, the answer is this because, in order to find the slope, you must use the formula y2-y1/x2-x1, and the y-intercept is found by using the formula y=mx+b, in which b is the y-intercept which leads to the awnser, y = −2x + 8.
Hi! Your answer is y = −2x + 8
Step-by-step explanation:
In order to find the slope, you have to use y2-y1/x2-x1 for the formula. The y-intercept can be found by using the formula y=mx+b. This means b is the y-intercept which makes the answer: y = −2x + 8.

14. Equation Editor Ryan downloaded a video
game to his computer. The size of the file
was 2.4 x 10 (5 th power) kilobytes. After the game was
installed, he downloaded a patch file for the
game that was 48,000 kilobytes in size.
(Lesson 6)
A. What is the size of the game in standard
form?
B. how many times larger was the game than the patch file
Part a: The size of the game in standard form is 240000 kilobytes
Part b: The game was 5 times larger than the patch file
Part A:
Size of the game downloaded by Ryan on his computer = 2.4 * 10^5
Size of the patch file for the game = 48000 kilobytes
Therefore, converting the size of the game into the standard form:
Size of the game = 2.4 * 10^5
= 2.4 * 100000
= 240000 kilobytes
Therefore, the size of the game is 240000 kilobytes in standard form
Part B:
Size of the game = 240000 kilobytes
Size of the patch file = 48000 kilobytes
Computing the size of the game with respect to the patch file we get:
=240000/48000
= 5
Hence, the game was 5 times larger than the patch file

By using the given pair of values we can see that the constant of proportionality is 8, and the proportional relation is:
y = 8*x
How to determine the proportional relation?A proportional relation is a linear relation with an y-intercept of 0, so these are written as:
y = a*x
Where a is the constant of proportionality.
By knowing a pair of values x and y, we can find the value of a. In this case we can see that when x = 3, y = 24, replacing that in the general equation we get:

A. $98, $122

The least and the greatest amounts are $98 and $112
How to determine the least and the greatest amounts?The food budget is modeled by 0.5|x - 110| = 6
So, we have:
0.5|x - 110| = 6
Divide both sides by 0.5
|x - 110| = 12
Remove the absolute bracket
x - 110 = 12 and x - 110 = -12

This gives
C = 1/4 * (5 + 10)

C = 3.75
Also, we have:
BD : DC = 3 : 5
