The answer is B, because if you graph the equations, the one that has the right maximum and distance is B. :)
Answer:
Step-by-step explanation:
A tiny hint. When you are looking for the opposite side of a triangle and the function you use is the tangent, the side opposite is always going to be larger than the side adjacent. That happens when theta is greater than 1 when the angle is larger than 45.
Phew! I didn't know the hint was going to be that long.
The trig function that does not involve the hypotenuse is the Tangent or Tan(x).
C
Tan(x) = opposite / Adjacent.
The opposite side is the side not connected to the reference angle (x)
The adjacent side makes up the angle and is not the hypotenuse.
Tan(46) = 1.036
Side adjacent = 8
So the answer is either A or C. I'm guessing it's C.
Tan(46) = x/8
1.036 = x / 8 Multiply by 8
8*1.036 = x
x = 8.28
Use pythagora's theorem to solve it
c^2=a^2+b^2
x^2=(3/4)^2+1^2
x^2=25/16
x= 5/4 = 1 1/4 inch
therefore it is B

-2x^2-11x^3

Answer:
55.89 % < X < 58.11%
Step-by-step explanation:
We have a Normal Curve.
P( L < Z < U ) = 95%
Two-tailed Confidence Interval.
L is above the 2.5%, so L = -1.96 from the chart
U is below the 2.5%, so U = 1.96
P( - 1.96 < Z < 1.96) = 95%
[(x - 57) / 3.5 ]* root(40) = -1.96
X = 55.915 Lower
(U - 57) / 3.5 *root(40) = 1.96
U - 57 = 1.96*3.5/root(40) = 1.08466
U = 58.084
so, from 55.9 < X < 58.1
