We have the following vectors:
 u = (a, b)
 v = (c, d)
 We observe that the vectors form an angle of 90 degrees.
 Therefore, the product u.v is equal to zero.
 We have then:
 u.v = (a, b). (c, d) = 0
 u.v = ac + bd = 0
 ac = -bd
 Answer:
 
B) ac = -bd

Naya [18.7K]

Answer:

b = 9 ft

Step-by-step explanation:

Pythagorean Theorem:

a^2 + b ^2 = c^2

Given:

a = 12

b = ?

c = 15

Plug in values:

12^2 + b^2 = 12^2

Solve for b^2:

b^2 = 15^2 - 12^2

b^2 = 225 - 144

b^2 = 81

Take square root of both sides to find b:

sqrt(b^2) = sqrt(81)

b = 9


Hope this helps! :)

Complete the table below to find solutions to the linear equation −4x+4y=16.
Rama09 [41]

Step-by-step explanation:

if x=4, then -4x4+4y=16

so, -16+4y=16

so, 4y=16+16=32

so, y=32/4

so, y=8

and x=4
