The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the ordered pair for the center.
(x - (- 3))² + (y - 6)² = 10²
(x + 3)² + (y - 6) = 100
Answer:
(√6)/2 square units
Step-by-step explanation:
The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.
QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)
QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)
The cross product is the determinant ...
![\text{det}\left|\begin{array}{ccc}i&j&k\\1&3&1\\0&-1&-1\end{array}\right|=-2i+j-k](https://tex.z-dn.net/?f=%5Ctext%7Bdet%7D%5Cleft%7C%5Cbegin%7Barray%7D%7Bccc%7Di%26j%26k%5C%5C1%263%261%5C%5C0%26-1%26-1%5Cend%7Barray%7D%5Cright%7C%3D-2i%2Bj-k)
The magnitude of this is ...
|QR × QS| = √((-2)² +1² +(-1)²) = √6
The area of the triangle is half this value:
Area = (1/2)√6 . . . . square units
Answer:
I think it is A and D but i'm sorry if i'm wrong
Step-by-step explanation:
Answer:
27.968 mins
Step-by-step explanation:
1) we need to find 8% of 32:
32*0.08=2.56
so 8% of 32 is 2.56 mins.
we need to subtract 2.56 by 32 since its says the times was cut by 8%
so
32-2.56=29.44
now 5% of 29.44:
29.44*0.05=1.472
1.472 mins
so
29.44-1.472=27.968
Hope this helps!
