Answer:
20.
Given, complex number is 10+5i .
We need to find sum of the given complex number and its conjugate. The conjugate of 10+5i is 10-5i. Therefore, the sum will be 10+5i+10−5i=20.
Answer:
it is an arithmetic sequence
m is slope
b is y-intercept
Step-by-step explanation:
The answer is 1,695.6 in³.
The volume of the empty space is the difference of the bigger cylinder and the smaller cylinder: V = V1 - V2
The volume of the bigger cylinder is:
V1 = π r² h
r = 10 in
h = 15 in
π = 3.14
V1 = 3.14 * 10² * 15 = 4,710 in³
The volume of the smaller cylinder is:
V2 = π r² h
r = 8 in
h = 15 in
π = 3.14
V2 = 3.14 * 8² * 15 = 3,014.4 in³
The volume of the empty space is:
V = V1 - V2 = 4,710 in³ - 3,014.4 in³ = 1,695.6 in³
Answer:
Step-by-step explanation:
<u>Given:</u>
- The slope m = -5 and point (2, -9)
<u>Use point slope form:</u>
- y - y₁ = m(x - x₁), where (x₁, y₁) is the given point
<u>So the equation is:</u>
- y - (-9) = -5(x - 2)
- y + 9 = -5x + 10
- y = -5x + 1
