A race car is driven around a circular track at a constant speed of 180mph. If the diameter is 1/2 mile, what is the angular spe

Bogdan [553]

If the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!

the angular speed is theta/time, which means

w=theta/time

but another formula for it is Velocity*radians

w=velocity*radians

velocity is 180 mph and radians are (revolution/2 $\pi$ radius), that is:

w=180*(1/2 $\pi$ *0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!

Write an equation to represent the following: Three consecutive integers add up to 11 more than the smallest.

mr Goodwill [35]

Answer:

Step-by-step explanation:

First we have to assume the smallest integer.

Let,

the smallest integer is x

So, the other two integers are-

x+1 and x+2

Now,

the sum of these 3 integers is greater than smallest integer by 11

So, we get

x+(x+1)+(x+2) =x+11

This is the required equation.

Find the missing lengths of the sides

Ket [755]

ANSWER

The correct answer is C

EXPLANATION

The given triangle is a right triangle. Since two angles are equal, it is a right isosceles triangle.

This implies that, x=8 units.

Using Pythagoras Theorem,

${y}^{2} = {8}^{2} + {8}^{2}$

This implies that:

${y}^{2} = 64 + 64$

${y}^{2} =128$

Take positive square root,

${y} = \sqrt{128}$

${y} = 8 \sqrt{2}$

The correct answer is C
