Answer:
y=-1/2x-3
Step-by-step explanation:
sorry if wrong form, there are like 6, but that is correct if in the right form
41.04 is your answer because product means you bed to multiply so you multiply 34.2×1.2 and you get 41.04
Answer:
40 mph
Step-by-step explanation:
To find the maximum speed at which the car can travel, as the distance it requires to stop is 168 feet, we just need to use the value of d = 168 in the equation, and then find the value of s:
168 = 0.05s^2 + 2.2s
0.05s^2 + 2.2s - 168 = 0
Using Bhaskara's formula: we have:
Delta = 2.2^2 + 4*0.05*168 = 38.44
sqrt(Delta) = 6.2
s1 = (-2.2 + 6.2)/0.1 = 40 mph
s2 = (-2.2 - 6.2)/0.1 = -84 mph (a negative value does not make sense as 's' is the speed of the car)
So the maximum speed of the car is 40 mph
Answer:-1.2
Step-by-step explanation:
Answer:
x = 6.5
Step-by-step explanation:
Since this is a right triangle we can use trig functions
cos theta = adjacent side / hypotenuse
cos 23 = 6/x
x cos 23 / 6
x = 6 /cos 23
x=6.51816
Rounding to the nearest tenth
x = 6.5
