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= $250 Sin \frac{\pi}{3}t$

Someone help PLEASE

Iteru [2.4K]

Answer:

Step-by-step explanation:

The perfect square:

$(a+b)^2=a^2+2ab+b^2$

We have

$y^2+14y+49=0\\\\y^2+2(y)(7)+7^2=0\\\\(y+7)^2=0\iff y+7=0\qquad\text{subtract 7 from both sides}\\\\\boxed{y=-7}$

We have

$y^2+16y+64=0\\\\y^2+2(y)(8)+8^2=0\\\\(y+8)^2=0\iff y+8=0\qquad\text{subtract 8 from both sides}\\\\\boxed{y=-8}$

Arrange the following polynomial into descending order for x, then interpret the degree of the 2nd term.

igor_vitrenko [27]

For the answer to the question above, the power of "y" doesn't influence descending order for x even if it is higher than power of x.

Unordered polynomial is
7x3y3 + 4 - 11x5y2 - 3x2y

Polynomial in descending order looks like this
-11x5y2 + 7x3y3 - 3x2y + 4

Degree of the second term is 5 ( because of x5 )
