Answer:
6x^4 -15x^3 + 3x^2
Step-by-step explanation:
What we want to do here is to multiply what is outside the bracket with what is inside
That would be;
3x^2(2x^2 -5x + 1)
= 3x^2(2x^2) -5x(3x^2) + 1(3x^2)
Opening the brackets, we have;
6x^4 -15x^3 + 3x^2
the answer would be (1, 7). because slope=change in y/change in x
This triangle seems like A) Scalene Acute. Brainliest meeeee!
Answer:
The volume of the solid is 243
Step-by-step explanation:
From the information given:
BY applying sphere coordinates:
0 ≤ x² + y² + z² ≤ 81
0 ≤ ρ² ≤ 81
0 ≤ ρ ≤ 9
The intersection that takes place in the sphere and the cone is:
Thus; the region bounded is: 0 ≤ θ ≤ 2π
This implies that:
ρcosФ = ρsinФ
tanФ = 1
Ф = π/4
Similarly; in the X-Y plane;
z = 0
ρcosФ = 0
cosФ = 0
Ф = π/2
So here;
Thus, volume:
V = 243
