The equation s =square root 30fd can be used to find the car's speed s in mph given the length d in feet of a skid mark and the friction factor f of the road. Police measured a skid mark of 90 feet on a dry concrete road. If the speed limit is 35mph, was the car speeding? Explain
Answers
Answer:
Yes, the car was speeding the speed limit.
Step-by-step explanation:
The given equation to find the car's speed, s (in mph), is
[tex]s=\sqrt{30fd}[/tex]
where, d is the length of the skid and f is the friction factor.
Police measured a skid mark of 90 feet, so d=90
As the road is dry and of concrete, therefore the friction factor, f=0.8.
So, the speed of the car
[tex]s=\sqrt{30\times0.8\times90} = 46.48[/tex] mph
The speed of the car is 46.48 mph which is more than the speed limit of 35 mph.
Hence, the car was speeding the speed limit.

Answers
Answer:
18
Step-by-step explanation:
Look at all factors of 9 that are even; 18, 36, 54, 72, 90
Next divide 198 by those numbers and the only whole number is from 18.
9 x 2 = 18

line I is the perpendicular bisector of MN. find m
Answers
Answer:
m = 68
Step-by-step explanation:
MN bisects it or splits it in half so we know N = M, which we could also write as 8x-12 = 5x+18 because they give us those equations
once you have 8x-12 = 5x+18 you can subtract 5x from both sides, so you will get 3x-12 = 18, then you can add 12 to both sides and you will get 3x = 30. Once you have narrowed down to this you can divide three by both sides making x = 10
Now that we know x =10 we can insert it into the equation
5(10) + 18 = m
50 + 18 = m
m = 68

What is Angles?
When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
In algebra, two lines can be represented as
a and b are constants in y=ax+ b.
(x,y)
on the Cartesian plane, are points.
Let's say two lines are depicted as
y1 = a1 (x + b1) and y2 = a2 (x + b2)
If and only if, the two lines are parallel.
As any line can be parallel to itself, either b1 is not equal to b2 or b1=b2 and a1=a2.
The characteristic of two simultaneous linear equations that have either no solution or an infinite number of solutions, but not exactly one solution, is another approach to define the term "parallel."
The final definition of the attribute of two lines being "Parallel" states that it is only possible for the X and Y axes to not be parallel to one another. It does not demand for the X and Y axes to be orthogonal to one another or that there be any particular angle between them.
This also applies to the situation of N axes.
Additionally, it is not necessary for Space to be Euclidean or for the 'lines' to be rectilinear.
