If t=-3 (hopefully it does) then it's 6+-12/10. This is -6/10=-3/5

A surfboard that has a regular price of $150 is on sale at a 40% discount. What is the sale price with a 9% tax?

Ahat [919]

Answer:

$98.10

Step-by-step explanation:

150 decrease 40% =

150 × (1 - 40%) = 150 × (1 - 0.4) = 90

90 increase 9% =

90 × (1 + 9%) = 90 × (1 + 0.09) = 98.1

Learning goal: to understand the rules for computing dot products. let vectors a=(2,1,−4), b=(−3,0,1), and c=(−1,−1,2). part a -

miv72 [106K]

For this case we have the following vectors:
$a = (2,1, -4)

b = (- 3,0,1)

c = (- 1, -1,2)$
The dot product of two vectors is a scalar.
The point product consists of multiplying component by component and then adding the result of the multiplication of each component.
For the product point of the vectors a and b we have:
$a.b = (2,1, -4). (- 3,0,1)

a.b = (2) (- 3) + (1) (0) + (-4) (1)

a.b = - 6 + 0 - 4

a.b = - 10$
Answer:
The product point of the vectors a and b is:
$a.b = - 10$
