Answer:
(3, -2)
Step-by-step explanation:
The dot product will have you multiply the corresponding coordinates and add up the products
v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13
Answer: -13
Answer:
Step-by-step explanation:
It is convenient to compute the areas in terms of grid squares. Then those results can be converted to square meters by multiplying by the area of a grid square: (10 m)² = 100 m².
(a) The area of the school is the product of its side dimensions. The short side is (in terms of grid squares) ...
W = √(1²+3²) = √10
The long side is ...
L = √(2²+6²) = √40
Then the area is ...
A = LW = (√40)(√10) = √400 = 20
The area of the school is 20 grid squares = 2000 m² . . . . . where s = 10 m
__
(b) The area of the museum is given by the formula ...
A = πr² = π(3)² = 9π grid squares = 2827 m²
The area of the museum is 2827 m².
__
(c) Marci says the museum has a larger area than the school. She is correct.
Marci should win the debate.
Uisng technology, such as a linear regression calculator or excel , the linear equation in slope - intercept format which models the data is 171.47x - 125.83
The relationship between <em>advertising cost</em><em> </em><em>and</em><em> </em><em>e-commerce</em><em> </em>sales is positive which can be inferred from the positive value of the slope which models the data. Also, since, the correlation Coefficient is high, we can expect to have a high e-commerce sales whenever, the advertising cost is high.
Therefore, the linear regression equation is 171.47x - 125.83
