Answer:
46.6 ft/sec (to the nearest tenth)
Step-by-step explanation:
There's a common identity useful here: 60 mph = 88 ft/sec.
Mult. 31.8 mph by the conversion factor (88 ft/sec) / (60 mph), obtaining:
46.64 ft/sec.
Answer:
is this supposed to say 7.7 x 
? if so then it's 770 (you move the decimal over 2 places to the right)
Answer: 
If using complex numbers, or undefined if using all real numbers
Step-by-step explanation:
Moving -8 to the left side of the eq by adding both sides by 8=
x^2-3x+8=0
The quad formula:
a=1 b=-3 c=8
Inserting a b c values into formula: 
Simplifying: 
Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.
OR
Using complex numbers i, to replace the negative number created by subtracting 9-32.
By definition,
sin(angle) = opposite/hypotenuse
From the picture,
sin(60°) = VT/PV
√3/2 = VT/35
√3/2*35 = VT
30.3 meters = VT
