3 = 2/3 m

m = 9/2

by the matrix property of associative: (A+B)+C = A+(B+C)

H = [-2 8 -1]

m x H = 9/2 x [-2 8 1] = [-9 36 -9/2]

2.3,2 4/5, 2.6 from least to greatest

Alex777 [14]

Hello there!

Least to greatest of these problem

For the fractions you can simplify it make it easier for you to solve these types of problems

Anyhow!

Let's find our answer, shall we?

$2.3 = 2.3 \\ \\ 2\frac{4}{5} = \frac{14}{5} = 2.8 \\ \\ 2.6 = 2.6$

Our answer: $2.3 \\ 2.6 \\ 2\frac{4}{5}$

Find cosØ if sinØ=-12/13 and tanØ>0. A) -5/12 B) -5/13 C) 12/5 D) -13/12

mestny [16]

Answer:

-5/13

Step-by-step explanation:

sin theta = opp / hyp

sin theta = -12 /13

we can find the adj side by using the pythagorean theorem

adj^2 + opp ^2 = hyp^2

adj^2 +(-12)^2 = 13^2

adj^2 +144 =169

adj^2 = 169-144

adj^2 = 25

Taking the square root of each side

adj = ±5

We know that it has to be negative since it is in the third quad

adj = -5

cos theta = adj / hyp

cos theta = -5/13
