Answer:
Step-by-step explanation:
Given
there are six integers to win a lottery
case-1 Integer not exceeding 40
no of ways to choose 6 incorrect numbers
Case-2 no of ways to choose 6 incorrect numbers out of 48 integers
Case-3 no of ways to choose 6 incorrect numbers out of 56 integers
Cae-4 no of ways to choose 6 incorrect numbers out of 64 integers
Answer:
2a
Step-by-step explanation:
using distance formula:
√(x₂-x₁)² + (y₂-y₁)²
putting values,
√{a-(a)}² + {b-b}² = √ {a+a}² + 0²
= √(2a)² = √4a² = 2a

C. 44 you need to do pendas
4050 ft is the total square footage of the house.
Let 
. The gradient of 
at the point (1, 0, 0) is the normal vector to the surface, which is also orthogonal to the tangent plane at this point.
So the tangent plane has equation
Compute the gradient:
Evaluate the gradient at the given point:
Then the equation of the tangent plane is
