Answer:

  √869 ≈ 29.48 square units

Step-by-step explanation:

The vector cross product is ...

  (3·1 -5·4, -6·1 +2·4, 6·5 -2·3) = (-17, 2, 24)

The area is the magnitude of this vector, so is ...

  √((-17)² +2² +24²) = √(289 +4 +576) = √869 ≈ 29.48

The area is about 29.48 square units.

Ben’s driving test had 40 questions and he correctly answered 12 more than he missed. How many questions did he miss?
k0ka [10]

Answer:

He missed 14 questions

Step-by-step explanation:

Total = Right + Miss ⇒ t = r + m

Right = Miss + 12 ⇒ r = m + 12

t = 40

Since t = r + m and r = m + 12 then:

t = m + 12 + m

t = 2m + 12

40 = 2m + 12

28 = 2m

m = 14

anastassius [24]

Solve and graph each of the following inequalities for x.
Ulleksa [173]

2x + 4 > 8

Step 1: Subtract 4 from both sides.

2x + 4 − 4 > 8 − 4

2x > 4

Step 2: Divide both sides by 2.

2x/2  >  4/2

x > 2

2x − 3 < 5

Step 1: Add 3 to both sides.

2x − 3 + 3 < 5 + 3

2x < 8

Step 2: Divide both sides by 2.

2x/2  <  8/2

x < 4
