Answer:
x = 9, WX = 34
Step-by-step explanation:
Two tangent segments to a circle from the same external point are congruent, that is
WX = YX, substitute values
7x - 29 = 2x + 16 ( subtract 2x from both sides )
5x - 29 = 16 ( add 29 to both sides )
5x = 45 ( divide both sides by 5 )
x = 9
Thus
WX = 7x - 29 = 7(9) - 29 = 63 - 29 = 34
Answer:
10, -5, -11
Step-by-step explanation:
f(x) = - 3x-5
f(-5) = -3(-5) - 5 => 15 - 5 => 10
f(0) = -3(0) - 5 => 0 - 5 => -5
f(2) = -3(2) - 5 => -6 - 5 => -11
Answer:
Ok hi im good at math just let me do this in ten mins ok
Step-by-step explanation:
we know that in 16.5 laps we get 37 miles, hmmm well the circumference of that circle is just 1 lap, how many miles is there in 1 lap?
Answer:
Step-by-step explanation:
If the engine torque y (in foot-pounds) of one model of car is given by y=−3.75x^2+23.2x+38.8
The engine speed is at maximum if dy/dx = 0
dy/dx = -2(3.75)x+23.2
dy/dx = -7.5x + 23.2
since dy/dx = 0
0 = -7.5x + 23.2
7.5x = 23.2
x = 23.2/7.5
x = 3.093
Hence the maximum torque is 3.09 rev/min
