Sophia want to rent an apartment she visits apartment A Whitehall charges $100 for a one time deposit and $400 per month for ren
Alex

Answer:

The inequality in this case is 100 + 400*t > 500 + 350*t and for B to be cheaper Sophia has to rent it for more than 8 months.

Step-by-step explanation:

In order to write the inequality we first need to write two equations one for each apartment. For apartment A we have a fixed cost of $100 and a variable cost of $400 that varies according to the time living in there, so we have:

rent = 100 + 400*t

For apartment B we have a fixed cost of $500 and a variable cost of $350 that varies according to the time living in there, so we have:

rent = 500 + 350*t

In order for the total paid in B to be less than for the one in A we need to satisfy the following inequality:

100 + 400*t > 500 + 350*t

400*t - 350*t > 500 - 100

50*t > 400

t > 400/50

t > 8 months

The inequality in this case is 100 + 400*t > 500 + 350*t and for B to be cheaper Sophia has to rent it for more than 8 months.

Find the area of the parallelogram determined by the vectors i +j+k and –2i + 3j + K.​
Wewaii [24]

The area of the parallelogram spanned by the given vectors is equal to the magnitude of their cross product.

(i + j + k) × (-2i + 3j + k)

= -2 (i × i) - 2 (j × i) - 2 (k × i)

… + 3 (i × j) + 3 (j × j) + 3 (k × j)

… + (i × k) + (j × k) + (k × k)

= - 2 (j × i) - 2 (k × i) + 3 (i × j) + 3 (k × j) + (i × k) + (j × k)

= 2 (i × j) - 2 (k × i) + 3 (i × j) - 3 (j × k) - (k × i) + (j × k)

= 5 (i × j) - 3 (k × i) - 2 (j × k)

= 5 k - 3 j - 2 i

Then the area of the parallelogram is

||-2 i - 3 j + 5 k|| = √((-2)² + (-3)² + 5²) = √38
