Answer: r≈1.96
Step-by-step explanation:
C=2πr
Solving for r
r=C
2π=12.3
2·π≈1.95761
Keeping in mind the formula for circumference is Pi x Diameter, you simply multiply 45 by pi.
This gives you 141.3716694
Answer:
y=-1/2x-1/2
Step-by-step explanation:
For this, you need to use the point slope formula, (y-y1)=m(x-x1). The slope, m, would be -1/2 since the line we're looking for is perpendicular (meaning the slope is the negative reciprocal of the original slope). The x1 would be 3, and the y1 would be 1.
(y-y1)=m(x-x1)
(y-1)=-1/2(x-3)
y-1=-1/2x-3/2
y=-1/2x-1/2
Answer:
0, 1, 2.
Step-by-step explanation:
5 - 3x <= 7
-3x <= 2
x >= -2/3 (the inequality sign flips as we are dividing by a negative value)
4x + 1 < 13
4x < 12
x < 3.
So the integer values satisfying the inequalities are>
0, 1, 2.
