Answer:
Radius = 7
Step-by-step explanation:
Since BA is tangent to circle O, it creates a 90° angle with the radius
Therefore, you can use Pythagorean theorem to solve this problem
a² + b² = c²
Let's say a is the radius
b is 5
c is 8.6
a² + 5² = 8.6²
a² + 25 = 73.96
Subtract 25 from both sides
a² = 48.96
Root both sides
a ≈ 6.997142274

Answer:
they will blink 4 times at the same time in one minute
Step-by-step explanation:
you have to find the least common multiple of 5 and 3
LCM of 5,3 = 15
So, the two lights will blink together every 15 seconds.
No.of times blinking together in one minute = 60/15 = 4
For linear functions, the rate of change<span> is constant, which means that it is the same between any two points on the line. For linear functions, the </span>rate of change<span> is the slope of the line.</span>
The answer 'quickly' could mean <span><span>fast, swiftly, briskly, rapidly, speedily, at the speed of light, at full tilt, as fast as one's legs can carry one, at a gallop, or on the double.</span></span>
