Answer:
r = 17 units
Step-by-step explanation:
The radius is the distance from the centre (- 7, - 1) to the point on the circle
(8, 7)
Use the distance formula to calculate the radius (r)
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 7, - 1) and (x₂, y₂ ) = (8, 7)
r = ![\sqrt{(8+7)^2+(7+1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%288%2B7%29%5E2%2B%287%2B1%29%5E2%7D)
= ![\sqrt{15^2+8^2}](https://tex.z-dn.net/?f=%5Csqrt%7B15%5E2%2B8%5E2%7D)
= ![\sqrt{225+64}](https://tex.z-dn.net/?f=%5Csqrt%7B225%2B64%7D)
=
= 17 units
Answer:
576 m
__________________________________________________________ The surface area of the triangular prism is (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh
For this question,
you know that the perimeter of the base is 6+10+8 which is 24.
and the length of the prism is 22,
so (22x24) + Base Area which is (6x8)/2-> 24x2
(22x24)+(24x2)= 528 + 48 = 576
so your answer is 576

Answer:
x is on the left side
Step-by-step explanation: I looked for it with my eyes
We can drop the absolute value and the signs, and the integer part if they're all the same, and then make a common denominator and check for a decreasing sequence.
10/12, 7/12, 5/12 -- Check decreasing
3 1/3, 3 2/3, 2 2/3 -- nope, increases then decreases
6 5/7, 6 3/7, 5 2/7 - Check, decreasing
11 7/10, 11 6/10, 10 3/10 -- Check, decreasing
Answer: A,C,D
