Answer:
It passes through the point (3,4). Given that the center of the circle is the point (0,0). We know that the equation of the circle is given by : (x-a)^2 + (y-b)^2 = r^2 where (a,b) is the center and r is the radius.
Answer:
the temperature is 75.5
Step-by-step explanation:
82 degrees - 6.5 degrees is 75.5 degrees
Truck speed be x
car travel at x+19
they travel in opposite directions
so the separation is (x+x+19) * no. of hours
1048 = (2x+19)*8
x = ((1048/8) - 19)/2
=56
truck speed is 56 miles per hour
car speed is 56+19 = 75 miles per hour
Answer:
2. tan 280°
3. -tan 80°
Step-by-step explanation:
Your calculator can help you figure this out.

The tangent function is periodic with a period of 180°, so tan(100°) will be equal to tan(100°+k·180°) for any integer k. Answer choices include k values of ±1, so two of them are correct:
- tan(100°) = tan(100° -180°) = tan(-80°)
- tan(100°) = tan(100° +180°) = tan(280°)
