The answer is a because when you’re dealing with positive Powers you do the one on the left first and when you do the one on the left you divide the second number by two and the second number 8 so now it is four. The one on the right you double the second number by two and the second number was four so now it is eight and when the number outside of the parentheses is negative you don’t do anything with it so that is why your answer is a. (And also five and four you keep the same because when even one of them has a negative in them you keep the two main numbers the same which are five and four.)

In the course of a short race, a car does 50,000 J of work in 7 s. What is the power of the car during the race? (round to the nearest whole number)

Answers

Answer:

Work done is the product of distance and force, it is measured in joules.

Power is the rate of work done given by dividing the work done by time

Power (watts)= workdone (J)/ time (s)

= 50,000J/7 sec

= 7142.857 watts

Therefore, the power of the car during the race was 7142.857 watts

Answer:

Step-by-step explanation:Much is usually anticipated about the fierce and decidedly bloody clashes between Wolverine and Victor Creed, the man known as Sabretooth, even though these men are arguably two sides of the same coin. Each of them has deadly claws that rend and draw blood; each has a generous amount of fear and intimidation working for them; each has a healing factor that prevents them from being mortally wounded (eventually reaching preposterous levels of effectiveness); and each has killed and will kill if the situation calls for it. Yet there are differences, as well: Logan's skeleton, as well as his claws, are made of the unbreakable metal known as adamantium; and while there have often been instances where he's been shown to be merciless, he's not nearly as sadistic as Creed, who will not hesitate to kill even when there is no reason for it. Perhaps the difference that keeps us engaged, however, is the fact

Answer:

We are given that:

variables x and y vary directly, this means that:

y = kx where k is the constant of proportionality

Now, we are also given that:

y = 45 at x = 40.

We will use these values and substitute in the above relation to get k as follows:

y = kx

45 = 40k

k = 45/40 = 9/8 = 1.125

Based on the above calculations, the equation that relates x and y is:

y = 1.125x

A=m/360pi times radius to the power of 2. Given the measure m of the angle and the radius r of a circle.

Find the measure of the angle if the area of the sector is 5 square centimeters and the radius is 2 centimeters. Round your answer to the nearest tenth.

Answers

Area of a Sector

$A=\dfrac{m}{360}*\pi r^2$

A = area of sectorm = measure of angle in degreesr = radius

Solving the Question

We're given:

A = 5 cm²r = 2 cmm = ?

Plug the given information into the equation and solve for m:

$A=\dfrac{m}{360}*\pi r^2\\\\5=\dfrac{m}{360}*\pi (2)^2\\\\5=\dfrac{m}{360}*4\pi \\\\\dfrac{5}{4\pi}=\dfrac{m}{360}\\\\m=\dfrac{5*360}{4\pi}\\\\m=143.2$

Answer

m = 143.2°

Answer:

m = 143.2 degrees.
