A rental car company charges $33.73 per day to rent a car and $0.06 for every mile
Tju [1.3M]

Answer:

430 > 33.73x + 27      ---->         x < 11

Step-by-step explanation:

The inequality describes the total amount that can be spent for a whole number of days. To solve for the number of days, solve for x (x<11.95). Because she can't rent for only a part of a day, and because she can't spend more than $430, the inequality becomes x<11.

If A, B, and Care 2x2 matrices; and det(A) = -2, det(B) = -3, and det(C)=-4 then compute: det(4C^TA^-1 C^TB^3) = 0 Official Time
almond37 [142]

Answer with explanation:

|A| = -2

|B|= -3

|C| = -4

|4 C^TA^{-1}C^TB^{3}|=4 |C||A|^{-1}|C||B|^3, \text{as}|C^T|=|C|,|A^n|=A^n\\\\=4 \times (-4) \times (-2)^{-1} \times (-4) \times (-3)^3\\\\=4 \times (-4) \times \frac{-1}{2} \times (-4) \times (-27)\\\\=-1728 \times \frac{-1}{2} \\\\=864

It should be 12cm because

h=height
a=area
b=base

h=a/b we have base 15cm and height 8cm

8cm=a/15cm
8cm*15cm=a
120cm^2=a

we then use the area to find the height with base 10

h=a/b
h=120cm^2/10cm

h=12cm
