Answer:
The value of n = 12
Step-by-step explanation:
Given the points
The slope formula
m = y₂-y₁ / x₂ - x₁


Given that the slope = m = 6
Thus, substituting the value
6 = n/2
n = 6 × 2
= 12
Thus, the value of n = 12
Answer:

Step-by-step explanation:
The equation of a circle with center (a,b) and radius r, is

From the question, the center of the circle is located at (-6,2) and the radius is

We substitute the center and radius to get:

Simplify to obtain:

Answer:
4 and 4?
Step-by-step explanation:
Answer:
a.V=5/6T
b. 350 ml
Step-by-step explanation:
a.
V∝T
or V=kT
where k is a constant.
V=250 ml
T=300° K
250=300 k
k=250/300=5/6
so V=5/6 T
b.
V=5/6 T
=5/6×420
=5×70
=350 ml
