Find the magnitude of a vector with initial point A(3, 4, 10) and terminal point B(8, 4, –2).

Fantom [35]

Answer:

Step-by-step explanation:

Use the distance formula in 3 dimensions

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1})^2 }$

with (x₁, y₁, z₁ ) = (3, 4, 10) and (x₂, y₂, z₂ ) = (8, 4, - 2)

d = $\sqrt{(8-3)^2+(4-4)^2+(-2-10)^2}$

= $\sqrt{5^2+0^2+(-12)^2}$

= $\sqrt{25+144}$

= $\sqrt{169}$

= 13 → B

A store is having a sale on jellybeans in trail mix. For 2 pounds of jellybeans and 12 pounds of trail mix, the total cost is $2

Tresset [83]

Answer:

The jelly beans cost $2.25 / pound

The trail mix costs $1.25 / pound

Step-by-step explanation:

Let +a+ = cost/pound of jelly beans

Let +b+ = cost/pound of trail mix

(1) 6a + 2b =16

(2) 3a + 5b =13

Multiply both sides by 2

and subtract (1) from (2)

(2) 6a -2b = -16

(1) -6a -2b = -16

8b=10

b=1.25

and

(1) 6a+2b=16

(1) +3a+b=8

(1) 3a+1.25=8

(1) +3a=6.75

(1) a=2.25
