Answer:

sine=opposite/hypotenuse

cosine=adjacent/hypotenuse

tangent=opposite/adjacent

a: 42

b: 135 km/h

Step-by-step explanation:

For part A, you are given the adjacent and opposite side lengths so you need to use the tangent formula. On the calculator, it is tan^-1 (90/100)

For part B, I used the pythagorean theorem and did 100^2+90^2= 18100 and then took the square root of that to get 135.

nlexa [21]

Answer:

option C is correct

Step-by-step explanation:

We need to find the determinant.

= -1(7*9 - 3*9)-( -3)(4*9 - 3*3) -2(4*9 -7*3)

= -1(63-27) +3 (36 - 9) -2( 36- 21)

= -1(36)+3(27)-2(15)

= -36+81-30

= 15

Option C is correct

3) A cable company had 595 subscribers. The ratio of regular subscribers to premium
IgorLugansk [536]

Answer:

280

Step-by-step explanation:

We know that there are at least 8 regular subscribers and there are at least 9 premium subscribers. And we know it's in that ratio. So the best way to start this is to divide 595 by 8+9 to get the single unit amount of both subscribers:

595/17 = 35

So one unit of anything is at least 35. Now, since we're looking for regular subscribers, we'll multiply this value by 8:

35*8 = 280

So 280 is our answer!
