Answer:
7/3
Step-by-step explanation:
3t^2 - 7t
T(3t-7)
T=0, 3t-7=0,.: t=7/3
The zeros are t=7/3
2root5y^2 +y-3 root 5
Pls does the root affect y tooo.
The precise name of quadrilateral ABCD is a square because there are 4 sides on a square and the quadrilateral is given has 4 points such as ABCD.
but don't take my word for it is not 100% sure
and I'm so sorry if I'm wrong
Step-by-step explanation:
length=x
width=x-1
x + x + (x-1) + (x-1) = 54
4x - 2 = 54
4x = 56
x = 14 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
Perimeter= x + x + (x-1) + (x-1)
54 ft = 14 + 14 + (14 - 1) + (14 - 1)
54 ft = 28 + (13 +13)
54 ft = 54 ft
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.
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
