Answer:
D = 6.71
Step-by-step explanation:
The distance formula is 
Decide which point will be Point 1 and Point 2.
Point 1: ( 1,3 ) x₁ = 1 y₁ = 3
Point 2: (-2, 9) x₂ = -2 y₂ = 9
Substitute the information into the formula.

Simplify within the brackets
Square each number
Add
Exact answer as a radical (root number)
Answer in decimals
Rounded answer to nearest hundredth
The nearest hundredth is the second place value. It rounds up because the value after it is "8", which is greater than 4.
Answer:
A = 27π cm² or A ≈ 84.823... cm²
Step-by-step explanation:
From being shown that the missing area is 90 out of 360°, we know that we need to find 75% of the area of the given circle.
Our equation is altered to: A = 0.75πr²
Plug in: A = 0.75π(6)²
Multiply: A = 27π cm²
If you were instructed to multiply pi and round (which is not as probable given that this is RSM), then the answer would be A ≈ 84.823... cm²
Y= Mx+b
In the equation of a straight line,the slope is the number "m" that is multiplied on the x, and "b<span>" is the </span>y<span>-intercept (that is, the point where the line crosses the vertical </span>y<span>-axis).</span>
√(43) = 6.55.
-3√(2) = -4.24...
√(43) > 3.6 > -3√(2)
A shape with 10 sides is a decagon.
