2, the answer is 2 guys, minimum not maximum no infinity!
The arrangement of the Eastern and Western lighthouses and the position of the boat are as shown in the attached diagram.
Using sine rule,
28/Sin 37 = 40/Sin B => Sin B = (40 Sin 37)/28 = 0.8597 => B = Sin ^-1(0.8597) = 59.287°
Therefore,
Angle E = 180 - (37+59.287) = 83.713°
Using the sine rule again;
BW/Sin E = 28/Sin 37 => BW = (28 Sin 83.713)/Sin 37 = 46.246 ≈ 46.27 miles.
The boat is 46.27 miles from the western lighthouse. The correct answer is A.
Answer:
7^22
Step-by-step explanation
Given the expression
7^8 × 7^3 × 7^4 × 7^7
In indices
a^m × a^n = a^{m+n}
The powers are added since the base are the same
We ate going to add all the powers of the expression given since they have the same base which is 7
7^8 × 7^3 × 7^4 × 7^7
= 7^{8+3+4+7}
= 7^22
= 3.91×10^18
Answer:
2340 ft^2
Step-by-step explanation:
Assume the width to be...x
then the length to be....x + 7
Perimeter = 2(x)+ 2(x + 7)....lm multiplying by two because there is two sides(length and width)
;194 = 2x + 2x + 14
; x(width) = 45ft
then the Area = 45 × (45 + 7)
;AREA = 2340 ft^2
The answer to this question is:
x = 1 + or - the square root of 47
