He is false the equation should be as follows
Answer:
The answer is 256 .
Step-by-step explanation:
To solve for the volume of the sphere, start by using the sphere volume formula, which is V = . However, in this formula, 3 will be used instead of (
).
Next, plug in the information given from the problem, and the formula will look like V = (3) (
).
Then, solve the equation, and the answer will be 256 .
Answer:
2x - y - 7 = 0
Step-by-step explanation:
Since the slope of parallel line are same.
So, we can easily use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (8, 9)
and m is a slope of line passing through (x₁, y₁).
and since the slope of parallel lines are same, so here we use slope of parallel line for calculation.
and, Slope = m =
here, (xₐ, yₐ) = (2, 7)
and,
⇒ m =
⇒ m = 2
Putting all values above formula. We get,
y - 9 = 2 ( x ₋ 8)
⇒ y - 9 = 2x - 16
⇒ 2x - y - 7 = 0
which is required equation.
