Find x. Round to the nearest tenth.
27
26.2
Answer:
14.0°
Step-by-step explanation:
Reference angle = x
Hypotenuse = 27
Adjacent = 26.2
Apply trigonometric function, CAH:
Cos x = Adj/Hyp
Cos x = 26.2/27
Cos x = 0.97037037
x = Cos^{-1}(0.97037037)
x = 13.9823107°
x = 14.0° (nearest tenth)

Step-by-step explanation:
An airplane is flying overhead at a constant elevation of 405 ft. A person is viewing the plane from a position 3040 ft from the base of a radio tower. The airplane is flying horizontally away from the person. If the plane is flying at the rate of 640 ft/s, at what rate is the distance between the person and the plane increasing when the plane passes over the radio tower? At the moment the plane passes over the tower, the distance between the person and plane is changing at a rate of ________ft/s
Answer:
δL/δt = 634,38 ft/s
Step-by-step explanation:
A right triangle is shaped by ( y = distance between aircraft and ground which is constant and equal to 405 f ) a person who is at ground level 3040 f away from the tower distance x = 3040 f and the line between the aircraft and the person. Then we can use Pythagoras theorem and write
L ( distance between aircraft and person )
L² = x² + y² or L² = x² + (405)²
Taken partial derivatives with respect to t we get:
2*L*δL/δt = 2*x*δx/t + 0
Then L*δL/δt = x*δx/dt
At the moment of the aircraft passing over the tower
x = 3040 ft δx/δt = 640 ft/s and L = √ ( 3040)² + (405)²
So L = √9241600 + 164025 L = √9405625 L ≈3066,9 ft
Then:
δL/δt = 3040*640/ 3066,9 units [ ft * ft/s / ft ] ft/s
δL/δt = 634,38 ft/s

Step-by-step explanation:
Can someone please help? f(x) = |x − 2| − 4 and g(x) = 1/2x − 2 solve algebraically for x.
Answer:
x = 8, x = 0 intercepts: (8,2) (0,-2)
Step-by-step explanation:
|x − 2| is a positive value, x can be x ≥ 2 or x ≤ 2
when x≥2, then
y = x-2-4 =x-6 and y = 1/2x - 2
x-6 = 1/2x-2
1/2x=4
x = 8
When x≤2
y = -(x-2)-4 = -x - 2
y = 1/2x - 2
-x - 2 = 1/2x - 2
x = 0

The ratio of boys to girls at Space Camp is 3:2. If there is a TOTAL of 60
campers, then how many of the campers are girls? *
Plz help it's due tomorrow
Answer:
Answer: B. 24
Step-by-step explanation: 60 divided by 5 is 12. Twelve times two (the amount of girls) is 24. Twelve times 3 (the amount of boys) is 36. Since 24 + 36 = 60, there are 24 girls and 36 boys.
Bill buys a large can of paint. The size of the can is measured in which unit?
Answer:
Barometer i think im not sure
Step-by-step explanation:
Pressure is a mechanical (non-electrical and non-magnetic) measure. All mechanical measures can be derived from just three basic mechanical units. Which three we use is actually arbitrary. This means that using three we can produce or define all other mechanical measures by multiplying or dividing some combination of the chosen three.
Most measuring systems use time, length, and mass as the basic three in which case pressure would be mass / (time * time * length * length). Compare that with kilogram per (meter*meter * second*second) which is also called a Pascal.
Another measuring system might use time, length, and force as the three basic measures. Here mass is omitted in place of force. Nothing is lost because mass and force can be written in terms of the other with the help of time and length. In this case pressure would be force / (length*length). Compare this with Newton per meter*meter which also defines a Pascal.
How pressure is measured in practice is another good question. The standard method is to use some device that employs a medium to compare the unknown pressure to some known familiar pressure. Mercury tubes illustrate this nicely and are still used in laboratories. They work because mercury is a very dense fluid. A lighter fluid can push upon and move a column of mercury but cannot pass through it.
Measuring the movement of mercury when a known pressure is applied to one end reveals the pressure at the other end. The persistence of millimeters of mercury (mmHg) as a unit for reporting pressure is testament to this method. Other pressure gages work by employing something like springs or strain sensors calibrated to mimic the readings that a mercury tube would report.
To rent a moving truck for the day, it costs $33 plus $1 for each mile driven.
You drive the truck 300 miles. How much do you pay? Show work
Answer: You will have to pay $333 dollars for 300 miles. Answer = $300
Step-by-step explanation: You start off with 33 dollars for renting a truck. Then, $1 = 1 miles. Multiply 1 x 300 and add 33 and you get 333. Hope this helps :).
Answer:
$333
Step-by-step explanation:
$33 for the truck which starts you off with 33 dollors
Then you drive 300 miles on the truck which is $1 each and 300x1= 300
next you add them both up which gives you $333
An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box.
The ending balance is $5,480.
Given that,
The initial balance is $4,000.The rate of interest is 6.5%.And, the time period is 5 years.Based on the above information, the calculation is as follows:
[tex]= \$4,000 \times (1 + 0.065)^5[/tex]
= $5,480
Therefore, the ending balance is $5,480.

Find the value of x that will make A||B
A-
2x + 50
5x - 80
B-
x = [?]
Answer:
30
Step-by-step explanation:
If A||B then the sum of given angles must be equal to 180°
2x + 50 + 5x - 80 = 180 add like terms
7x - 30 = 180 add 30 to both sides
7x = 210 divide both sides by 7
x = 30
