Answer:
The correct option is 2. The circle has a radius equal to 7.
Step-by-step explanation:
It is given that center of a circle is at the origin on a coordinate grid.
The standard form of the circle is
Where (h,k) is center of the circle and r is radius.
The equation of the circle is
The line intersects the circle at (0,7) it means the point lies on the circle.
Put x=0 and y=7 in the above equation.
Therefore the radius of the circle is 7 units.
The line is passing through the point (0,7) with positive slope. Two points are required to find the slope of a line.
Since we have a single point therefore we cannot find the slope of the line. Second option is correct.
Answer: A (y = 1)
Step-by-step explanation:
when dividing, dividing by 0 equals an undefined fraction, therefore, if y was equal to 1, it would cancel out the y - 1, making it 0. I hope that's right :0
Step-by-step explanation:
Law of Indices:
a^m * a^n = a^(m + n)
Hence,
8^(-8) * 8^(3) = 8^(-8 + 3) = 8^(-5).
