Answer:
Step-by-step explanation:
115% = 115/100 = 1.15
of means multiply
1.15 * 95 = 109.25
Slope (m) = y2-y1 / x2-x1
m = 7 - 4 / 0 + 5
m = 3 / 5
In short, Your Answer would be 3/5

Sin 30=opposite side/hypotenuse =8/x
1/2=8/x so 1•x=2•8; x=16
Sin60= opposite side/hypotenuse=y/16
(Sqrt 3)/2=y/16 so 2•y=16• sqrt 3; y=13.856
We can find the answer by solving the two equations simultaneously.
equation 1: y = -0.4x^2 +3xequation 2: x + y = 10
We need to write equation to with y as the subject:equation 2: y = 10 - x
equation 1 = equation 2:
10 - x = -0.4x^2 + 3x0.4x^2 - 4x + 10 = 02x^2 - 20 + 50 = 0(2x - 10)(x - 5) = 0x = -10/2 or x = 5
But x >= 0 (the question says it's a height above the water), so x = 5
Substituting x = 5 into one of the equations:
y = 10 - x
y = 10 - 5
y = 5
So the answer is C
