That... OR the answer is 205848X
HELP PLS! A boat is heading towards a lighthouse, whose beacon-light is 102 feet above the water. From point AA, the boat’s crew measures the angle of elevation to the beacon, 13^{\circ}
, before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 22^{\circ}
. Find the distance from point AA to point BB. Round your answer to the nearest tenth of a foot if necessary.
Answer:
Distance from point AA to point BB = 189.3 feet
Step-by-step explanation:
Let the distance from point AA to the base of the lighthouse be represented by x, and the distance from point BB to the base of the lighthouse be represented by y. So that;
distance from point AA to point BB = x - y
To determine the value of x, applying the required trigonometric function;
Tan θ = [tex]\frac{opposite}{sdjacent}[/tex]
Tan 13 = [tex]\frac{102}{x}[/tex]
x = [tex]\frac{102}{Tan 13}[/tex]
= 441.81 feet
x = 441.8 feet
To determine the value of y;
Tan 22 = [tex]\frac{102}{y}[/tex]
y = [tex]\frac{102}{Tan 22}[/tex]
= 252.46
y = 252.5 feet
Thus,
distance from point AA to point BB = 441.8 - 252.5
= 189.3 feet

Sum of a finite geometric series:
Q] - a
Sn =
1-T
Answer:
[tex]sum = \frac{a( {r}^{n - 1} )}{r - 1} \\ : but \: l = a( {r}^{n - 1} ) \\ 49152 = 3( {2}^{n - 1} ) \\ 16384 = {2}^{n - 1} \\ {2}^{n} = 32768 \\ {2}^{n} = {2}^{15} \\ n = 15 \\ \therefore \: sum = \frac{3(2 {}^{15 - 1}) }{15 - 1} \\ = \frac{49152}{14} \\ = 3510.9[/tex]

Find the mean:40,13,49,53,35
Find the Range:40,13,49,53,35
Find the median:40,13,49,53,35
Answer:
mean: 38
range: 27
median: 40
Step-by-step explanation:
mean: 40+13+49+52+35 / 5
range: 40 - 13
median : 40
Answer:
Mean = 38
Range = 40
Median = 40
Step-by-step explanation:
Arrange the terms in ascending order :
13, 35 , 40 , 49 , 53
[tex]Mean = \frac{40 + 13 + 49 + 53 + 35}{5} = 38[/tex]
[tex]Range = {53 - 13} = 40[/tex]
[tex]Median = \ the \ middle \ term = 40[/tex]

Mike works h hours in a week. To find his weekly pay he multiplies his hours by his pay of $30 per hour and adds $5 for his sales bonus. He's decided that he wanted to take one-fifth of his weekly pay and place it in his savings. Which simplified expression represents the amount that will go into his savings each week?
Answer:
6h + 1
Step-by-step explanation:
number of hours: h
pay per hour: 30
pay for the hours: 30h
add sales bonus: 30h + 5
1/5 of total above: (1/5)(30h + 5) = 6h + 1
Answer: 6h + 1

How many solutions are there to the following equation?
2- 5x= 3(2 – 3x)
A. O
B. 1
C. Infinitely many
This was wrong.. Why?
Answer:
I think it's 9/22
Step-by-step explanation:
Probability of A given B = (probability of A and B)/probability of B
[tex]\frac{(14/22)(9/22)}{14/22} \\=\frac{9}{22}[/tex]
P(B) = P(1 checked bag) = 14/22
P(A) = P(silver status) = 9/22
P(A ∩ B) = (14/22)(9/22)
