The answer is 5.14 ur well come (instagram:2k15sgraduate_bish_where)
(3*c)-7
The product of 3 and c means they would be multiplied and since it’s 7 less than you would subtract 7 from the product
Step-by-step explanation:
Hey there!!
During evaluating the expression, you must follow,
- put the value as given.
- work according to the mathematical operation sign.
Here,


= 30+36
= 66.
ii). b-4c
= 30 - 4×6
= 30 - 24
= 6

Answer:
2236.77 feets
Step-by-step explanation:
From the attached picture, we are to find x, which is the vertical depth of the submarine.
Using trigonometry based on the illustration in the diagram:
Sinθ = opposite / hypotenus
Sinθ = x (depth of submarine) / distance from ship (4000)
Hence,
Sinθ = x / 4000
θ = 34°
Sin34 = x / 4000
0.5591929 * 4000 = x
2236.7716 = x
Hence, depth of submarine = 2236.77 feets
The formula for the law of cosines is:
a^2 = b^2 + c^2 - 2*b*c*cos(angle)
In this triangle b = 7, c = 8 and angle = 32.
a^2 = 7^2 + 8^2 - 2*7*8*cos(32)
a^2 = 18.018
a = SQRT(18.018)
a = 4.24
C = 4.2 feet.
