Answer:
The answer would be OA. PO and G) = 0.67
Answer:
The notation "f(x)" is exactly the same thing as "y"
Step-by-step explanation:
The effect of using f(x) instead of y is that it allows us to talk about f.
If we have an equation relating X to Y then that's a relationship between rwo nimbers.
For example if you have that y=
...then that means that X and Y are some numbers obeying that equation
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
Step-by-step explanation:
4√2 + √2 = 5√2 we add 4 and the invisible 1 in front of √2, the common root stays same
8√3 - 4√3 = 4√3 subtract 4 from 8 the common root stays same
2√3 x √32 ➡ 2√3 x 4√3 too add the expressions we first need to make the roots common then add 4 and 2
