So for the first one what you did was wrong as in wrong formula.
Radius is 5cm as it is given and diameter is double the radius which is 10.
So r=5
And D=10.
For the second one the diameter is 16cm as it is given and radius is half the diameter,so half of 16 is 8cm right?
So r=8
And D=16
Y=4x^2+16x-48
Start with factoring (x-2)(x+6) using distribution
Then multiply it by 4
35%
7/20
Multiply both sides by 5.
35/100
35%
Answer:
yes
Step-by-step explanation:
0.5 and 59 are very far apart- picking at random, 7 is between them. 7 is a natural number, which is a subset of rational numbers. Most numbers are rational, irrational numbers are things like pi
Answer:
Parallel
Step-by-step explanation:
In the slope-intercept form (y=mx +c), the coefficient of x tells us the slope of the line.
2x +8y= 56
Let's rewrite this equation into the slope-intercept form.
8y= -2x +56
Dividing both sides by 8:
Slope= -¼
y= -¼x -5
Slope= -¼
Since both lines have the same slope, they are parallel to each other.
