An airplane takes off at an angle of 15 degrees with the ground. To the nearest 10 feet, how far has the airplane flown when it has covered a horizontal distance of 1800 feet?
Answers
Answer:
1738.67 feet
Step-by-step explanation:
Imagine a right angles triangle, with the base length of 1800ft and the angle between the base and the hypotenuse to be 15 degrees.
Now, we have to calculate the hypotenuse length, using trigonometric ratios
The ratio that links adjacent side and hypotenuse is cos
So, write an equation:
cos(15) = Adjacent/Hypotenuse = 1800/H
Rearrange to solve.
H = cos(15) x 1800 = 1738.67
This is the distance flown by the aeroplane .

Because all the other choices are quadratic
Answer:
B
Step-by-step explanation:
A linear function is described by a x term to the power of 1 or even 0. A function when x is to the second power is most usually not a linear function.
In answer A, you have x multiplied against -3x. This will cause an x squared term, so this is not a linear function.
In answer B, you have 1/2 multiplied against x, which is a regular x term subtracted by 2x, causing a regular x term, meaning this function is linear. However, in the small possibility it is not, we will keep going.
In answer C, there is an x squared term so this is not linear.
In answer D, the expression has 1/2x times 2x, which will cause an x squared term.
Thus, the answer is B, which is the only equation without an x squared term.

if p is inversely proportional to the square of q, and p is 9 when q is 5, determine p when q is equal to 3
Answers
Answer: tell me if i am wrong
p = 304
Step-by-step explanation:
Given p is inversely proportional to q² then the equation relating them is
p = [tex]\frac{k}{q^{2} }[/tex] ← k is the constant of proportion
To find k use the condition p = 19 when q is 8, then
19 = [tex]\frac{k}{8^{2} }[/tex] =[tex]\frac{k}{64}[/tex] ( multiply both sides by 64 )
k = 1216
p = [tex]\frac{1216}{q^{2} }[/tex] ← equation of proportion
When q = 2, then
p = [tex]\frac{1216}{2^{2} }[/tex]=[tex]\frac{1216}{4}[/tex]=304
Name each pair of angles as corresponding, alternate interior, alternate exterior, or consecutive. Then solve for x.
Answers
Answer:

Step-by-step explanation:
These 2 angles are alternate exterior so they're equal to each other.
x + 127 = 125

Step-by-step explanation:
The measure of x if the measure of arc DC= 95 degrees is: 47.5.
Measure of arc DCBased on the diagram, since the angle is half of the arc in order to determine the measure of x will would divide 95 degree by 2 .
Hence:
Measure of x= 95/2
Measure of x= 47.5

Michael is considering four different job offers. He estimates that 12% of his income will go to his taxes. He created a table in order to determine how much his take home pay will be from each job.
Answers
Answer:
Michael's take home pay from each job are;
[tex]\begin{array}{cccc}Gross \ Income& Take \ home \ Pay\\\$1,250& \$1,100\\\$1,525 &\$1,342\\\$1,850&\$1,628\\\$2,200&\$1,936\\\\Sum&\$6,006\end{array}\\[/tex]
Step-by-step explanation:
The given parameters are;
The percentage of Michael's income that he estimates will go to his taxes = 12%
The number of jobs Michael has = Four jobs
The table Michael created can be presented and the estimated taxes and the take home pay entered as follows;
Tax owed = Gross income × Tax percent
Take home pay = Gross income - Tax owed
[tex]\begin{array}{cccc}Gross \ Income& Multiplied \ by \ Tax \ Percent &Taxes \ Owed& Take \ home \ Pay\\\$1,250&\times \ 0.12 =&\$150& \$1,100\\\$1,525 &\times \ 0.12 =&\$183&\$1,342\\\$1,850&\times \ 0.12 =&\$222&\$1,628\\\$2,200&\times \ 0.12 =&\$264&\$1,936\\\\Sum&&\$819&\$6,006\end{array}\\[/tex]

A rocket is launched into the air. The height h(t), in yards, of the rocket is a function of time, t, in seconds, as shown in the following table.
What is the rocket's average rate of change from 3≤t≤6 in yards/second?
Enter your answer as a number, like this: 42
Answers
Answer:
From 3 to 6 seconds, the rocket is falling 11 yards per second.
Step-by-step explanation:
Normal pace of progress is exactly the same thing as the slant. Since this is explanatory, we can't track down the specific pace of progress as we could if this were a straight capacity. Be that as it may, we can utilize a similar thought. At the point when t = 3, h(t) = 33, so the organize point is (3, 33). At the point when t = 6, h(t) = 0, so the facilitate is (6, 0). Attachment those qualities into the incline recipe:
m= 0-33/6-3 and m=-33/3 which is 11
From 3 to 6 seconds, the rocket is falling 11 yards each second.
