7,800 is greater than 2,500 tens
Hmmm to tell if they're orthogonal(perpendicular) to each other, we can simply get their dot-product, if their dot-product is 0, then they indeed are perpendicular, let's check
well, no luck there... now, let's introspect the digits a little
notice, the second vector, -28, 16, is just a multiple of the first one, that simply means, they're
parallel.
you can always just do a b/a check and simplify both vectors, if they yield the same ratio, they're parallel, since they're just multiples of each other.
ANSWER
2π/3 rad ≈ 2.1 rad
EXPLANATION
The arc length of a portion of a circle with central angle θ and radius r is,
In this case, we know that the arc length is s = 10π/3, the radius is 5, and we have to find the central angle. Solving the equation above for θ,
Substitute the known values and solve,
Hence, the angle is 2π/3 radians or 2.1 radians - this last result is rounded to the nearest tenth.
The slope of the best fit for the 3 given points is 500, so the correct option is b.
<h3>
How to find the slope?</h3>
Remember that for a line that passes through two points (x₁, y₁) and (x₂, y₂) the slope is:
With the 3 given points we can find 3 slopes, and then we will need to find the average of these 3.
The 3 points are: (3, 2,750), (6, 4,200), and (9,5,750)
Then the 3 slopes are:
The average slope is:
So the correct option is b.
