a switch board display in the store allows a customer to hooktogether any selection of components (consisting of one of eachtype). use the product rules to answer the followingquestions.

240

Step-by-step explanation:

As per given ,

Number of choices for Receiver = 5

Number of choices for CD Player= 4

Number of choices for Speakers = 3

Number of choices for Cassette Deck =4

If a switch board display in the store allows a customer to hook together any selection of components , then by product rule

The number of ways one component of each type be selected = (Number of choices for Receiver) x (Number of choices for CD Player) x (Number of choices for Speakers )x (Number of choices for Cassette Deck)

= 5 x 4 x 3 x 4 = 240

Hence, the answer is 240.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
