Determine a scalar c so that the angle between a = i + cj and b = i + j is 45°.​
Marina CMI [18]

Answer:

c=0

Step-by-step explanation:

ATQ a.b=|a||b|sin(45)

1+c=sqrt(1+c^2)*sqrt(2)*1/sqrt(2)

1+c=sqrt(1+c^2)

(1+c)^2=(1+c^2)

2c=0, c=0

Think about converting 48% to an equivalent fraction in reduced form. If the denominator is 25, what is the numerator?
bulgar [2K]

Answer:

the numerator is 12

Step-by-step explanation:

since 48 is a percent, it would be put as 48/100 as a fraction. since both the numerator and denominator are divisible by 4, you can reduce the fraction into 12/25. Since the question is asking what the numerator was when the denominator was 25, the answer is 12.

<h3>Given</h3>
  • ∠AOB = ∠COD = x² -2
  • ∠BOC = 2x -10
  • ∠AOD = ∠AOB + ∠BOC + ∠COD = 16x +2
<h3>Find</h3>
  • x
  • the measures of the angles
<h3>Solution</h3>

Substituting the given values of the angles into the given relaion, we get ...

... (x² -2) + (2x -10) + (x² -2) = 16x +2

... 2x^2 -14x -16 = 0 . . . . . subtract the right side (16x+2)

... 2(x +1)(x -8) = 0 . . . . . . .factor

Values of x that satisfy this equation are ...

... x = -1, x = 8

The value x = -1 does not give rise to positive angle values.

For x = 8, the angles are ...

... ∠AOB = ∠COD = 8²-2 = 62

... ∠BOC = 2·8 -10 = 6

... ∠AOD = 16·8 +2 = 130 . . . . = 62 +6 +62

The answer to the question not asked is ...

... x = 8; ∠AOB = ∠COD = 62; ∠BOC = 6; ∠AOD = 130
