Answer:
12
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 9^2 = 15^2
a^2 +81 =225
Subtract 81 from each side
a^2 = 225-81
a^2 = 144
Take the square root of each side
sqrt(a^2) = sqrt(144)
a=12
Answer:
a = 12 meters
Step-by-step explanation:
Use pythagorean theorem to identify the missing leg
pythagorean theorem = [tex]a^2+b^2=c^2[/tex]
In this case, we are looking for a so...
[tex]a^2+b^2=c^2[/tex]
[tex]a^2+9^2=15^2[/tex]
[tex]a^2+81=225[/tex]
[tex]a^2=225-81[/tex]
[tex]a^2=144[/tex]
It doesn't make sense for a to be equal to 144 so we must square root 144
144 = [tex]12^{2}[/tex] meters
Final Answer: 12 meters

A ship is at a distance of 200 m from a tall tower. What is the angle of depression (to the nearest degree) of the ship found by a man after climbing 50 m up the tower?
Answers
Answer:
14degrees
Step-by-step explanation:
Given the following
Distance of ship from the tower = 200m
Height of the tower = 50m
Required
Angle of depression theta
USing the SOH CAH TOA identity
Tan theta = opposite/adj
Tan theta = 50/200
Tan theta = 1/4
theta = arctan(0.25)
theta = 14.03degrees
Hence the angle of depression is 14degrees

A flight has 175 passengers. 3 of them will be chosen to get an upgrade to first class. How many groups of 3 are possible?
Answers
Answer:
877975
Step-by-step explanation:
Given that :
Total number of passengers, n = 175
Number who gets an upgrade, x = 3
Number of different groups who could get an upgrade :
We solve this using combination :
nCr = n! ÷ (n-r)!r!
175C3 = 175! ÷ (175 - 3)!3!
175C3 =175! ÷ (172)!3!
175C3 = 877975
Which expression is equivalent to (3x + 4)(2x - 3)?
Answers
Answer:
Step-by-step explanation:
If there are choices, you should list them. It's a guess about which is correct. I'll list 2 of them.
(3x + 4)(2x - 3) can be
(2x - 3)(3x + 4) or
F: 3x*2x = 6x^2
O:3x * -3 = - 9x
I : 4 * 2x = 8x
L: 4 * - 3 = - 12
When added, you get
6x^2 -9x + 8x - 12
6x^2 - x - 12

A rectangular tank measures 13 cm by 8 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many liters?
Answers
Answer:
10400MM
1.04 litre
Step-by-step explanation:
volume = length x width x height
13 x 8 x 10 = 1040 cm^3
1cm = 10 mm
1040 x 10 = 10400MM
1cm = 0.001 litres
1040 x 0.001 = 1.04 l

Answers
Answer:
g = 81.
Step-by-step explanation:
f = k/√g where k is a constant
When f = 12 g = 36, so:
12 = k/√36 = k/6
k = 12*6 = 72.
So the relation is:
f = 72/√g
When f = 8:
8 = 72/√g
8√g = 72
√g = 72/8 = 9
g = 9^2 = 81.

Find the area of a circle with the radius of 73 feet
Answers
Answer:
Step-by-step explanation:
area of a circle=πr^2
=3.14*(73)^2
=3.14*5329
=16733.06 ft^2
Answer:
A = 5329 pi ft^2
If we approximate pi with 3.14
A = 3.14*5329=16733.06 ft^2
If we use the pi button
A =16741.54725 ft^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
The radius is 73
A = pi ( 73) ^2
A = 5329 pi ft^2
If we approximate pi with 3.14
A = 3.14*5329=16733.06 ft^2
If we use the pi button
A =16741.54725 ft^2
