Answer:
m = 1/2 point (5, -7)
Step-by-step explanation:
The equation is in point slope from
y - y1 = m(x-x1)
where m is the slope and (x1,y1) is a point on the line
y+7 = 1/2(x-5)
Rewriting
y - -7 = 1/2 (x - 5)
We can see that 1/2 is the slope and (5, -7) is a point on the line
Answer:
Short answer: D) 15
Step-by-step explanation:
Parallel lines in this kind of triangle are always in a strict ratio of small to large or large to small based on how you look at it.
So we have 4cm to 6cm, which is 2:3 ratio. We know the smaller side, but want the larger side, so we can set up 2/3 = 10/?
the ? is 15.
For example, let's say b=30. If you divide 30 by 10, you get 3(obviously). But if you divide 10 into 30, you get -3.
Volume of a sphere = (4/3) (pi) (radius)³
The sphere's volume is proportional to the cube of its radius,
so the radius is proportional to the cube-root of the volume.
The only way to double a sphere's volume is to increase
its radius by the factor of
∛2 = 1.26 (rounded).
