Answer:
Step-by-step explanation:
in quadrant 1 cos and sec are positive.
cos(θ)=√(1-sin²θ)=√(1-(12/13)²)=√((169-144)/13²)=5/13

What is the value of x?
Enter your answer in the box.
X =
Answer:
x=5
Step-by-step explanation:
According to the Pythogoras Theorem,
(hyp)^2 = (opp)^2 + (adj)^2
(13)^2 = (12)^2 + (x)^2
169 = 144 + (x)^2
(x)^2 = 25
x = 5

Which expression is equivalent to (3x + 4)(2x - 3)?
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 flight has 175 passengers. 3 of them will be chosen to get an upgrade to first class. How many groups of 3 are possible?
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
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?
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

Answer:
A) 4 cats
Step-by-step explanation:
let x = 16-y
substitute to get:
18(16-y) + 30y = 432
288 - 18y + 30y = 432
12y = 144
y = 12
x = 4

make m the subject in the relation
[tex]2m - x + 3y \h = 2y \p[/tex]
Answer:
[tex]m = \frac{-y+x}{2}[/tex]
Step-by-step explanation:
[tex]2m - x + 3y = 2y[/tex]
Take [tex]-x[/tex] and [tex]+3y[/tex] on the other side of the equal to sign:
[tex]2m = 2y +x-3y[/tex]
Now solve for y:
[tex]2m = -y +x[/tex]
Take 2 one the other side of the equation:
[tex]m = \frac{-y +x}{2}[/tex]

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?
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

f
is inversely proportional to
√
g
.
When
f
=
12
,
g
=
36
Work out
g
when
f
=
8
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
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

The probability for event A is 0.4, the probability for event B is 0.2, and the probability of events A and B is 0.1.
Why are the events not independent?
The sum of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is not equal to P(A and B).
The sum of P(A) and P(B) is not equal to P(A and B)
Answer:
the correct answer is the product of PA) and P(B) is not equal to P(A and B)
