ANSWER
EXPLANATION
The dimensions of a matrix is of the form:
The dimensions of the first matrix is
The dimensions of the second matrix is
Since the inner products are the same,the outer products give the dimensions of the product of the two matrices.
Therefore the dimensions of the product is a 2×2 matrix.
I did number 6 to give you an idea of what you have to do. First find simplify the top and bottom and reduce!
Hope it helps! Comment if you have any questions!
D) Vertices: (1, -1), (-11, -1); Foci: (-15, -1), (5, -1)
Hello from MrBillDoesMath!
Answer: b = 4, h = 13
Discussion:
For a triangle with base b" and height "h, the area formula is
A= (1/2)bh.
In our case A = 26, h = 5b-7, so
26 = (1/2) b (5b-7). Multiply both sides by 2:
26*2 = b(5b-7) =>
52 = b(5b-7) =>
52 = 5b^2 - 7b => (subtract 52 from both sides)
5b^2 - 7b - 52 = 0. This factors as follows:
(b - 4) (5 b + 13) = 0 (use quadratic formula to find this)
so b = 4 and h = 5b -7 = 5*4 - 7 = 13
Thank you,

Answer:
The distance she bikes is 11/6 times as much as the distance she runs.
Step-by-step explanation:
Alex bikes 2.75 miles, runs 1.5 miles. The distance she bikes is 2.75/1.5 times as much as the distance she runs.
The distance she bikes is 11/6 times as much as the distance she runs.
