in a car race feild(round track that is 500m diameter an observer was starting point and the race started a red car finished 5 l

Eddi Din [679]

Answer:

Distance between the observer and the red car is $250 Sin \frac{\pi}{3}t$

Step-by-step explanation:

Diameter of field = 500 m

Radius of field = $\frac{Diameter}{2}=\frac{500}{2}=250 m$

Let R be the radius and the speed at which the car completes race be w

So, $w=\frac{2\pi}{T}$

Car finished 5 laps in minutes = 30

Car finished 1 lap in minutes = $\frac{30}{5}=6$

So, $w=\frac{2\pi}{6}=\frac{\pi}{3}$

Refer the attached figure

Angle between car and observer = wt

So, Distance between the observer and the red car is give as A sin wt

So, Distance between the observer and the red car= $250 Sin \frac{\pi}{3}t$

How does the length of the hypotenuse in a right triangle compare to the lengths of the legs?

gavmur [86]

we know that

In a right triangle we have

two legs and one hypotenuse

Let

a,b -----> the legs of the right triangle

c-----> the hypotenuse of the right triangle (the greater side)

Applying the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$

therefore

<u>the answer is</u>

The length of the hypotenuse squared is the length of one leg squared plus the length of another leg squared

If n denotes a number to the left of 0 on the number line such that the square of n is less than 1/100, then the reciprocal of n

andriy [413]

Answer: E. Greater than 10

Step-by-step explanation:

First, know that number to the left of a number line are negative and the square of any negative number will be positive and a perfect square.

Since the square of the unknown number is less than 1/100 i.e 0.01 then the possible unknown number 'n' can be -0.01 itself, of which the square of -0.01 will give us 0.0001 (1/10,000) i.e a value less than 0.01.

The reciprocal of 1/10000 is 10,000 which is a value greater than 10.

Find the value of both variables.

ella [17]

$\cos(45) = \frac{5 \sqrt{2} }{x} \\ \frac{1}{ \sqrt{2} } = \frac{5 \sqrt{2} }{x} \\ x = 10 \\ \\ \tan(45) = \frac{y}{5 \sqrt{2} } \\ 1 = \frac{y}{5 \sqrt{2} } \\ y = 5 \sqrt{2}$

I hope I helped you ^_^

A box contains10 pens, 5 of the pens are red, 4 are balck and 1 are bluem What is the probability of pulling out a black pen fir

antiseptic1488 [7]

Pulling out a black pen first will grant you a 40% chance of that occurring, then when you put it back the probability of you pulling out a red pen would be 50% so in decimal form these two values would be .40 and .50 multiply these two together you should get .20 or a 20% chance. Also a written fraction would be 1/5, all of which are valid answers.
