You have a weekend job selecting speed limit signs to put at road curves. the speed limit is determined by the radius of the curve and the bank angle. part a for a turn of radius 280 m and a 7.0∘ bank angle, what speed limit should you post so that a car traveling at that speed negotiates the turn successfully even when the road is wet and

idk

step-by-step explanation:

idk

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
