Answer:

Option 2). -4/3 is the correct answer

Step-by-step explanation:

It is given that,

sin Ø = - 4/5 and cos Ø>0.

sin Ø = opposite side/hypotenuse = - 4/5

Adjacent side = square root (hypotenuse² - opposite side²)

= square root (5² - 4²) = √9 = +3 or -3

cos Ø =Adjacent side/hypotenuse

It is given that, cos Ø>0

cos Ø = 3/5

Therefore  tan Ø = Opposite side/Adjacent side = 4/3 or -4/3

The second option is the correct answer -4/3

Answer:

187.74\:\mathrm{cm}

Step-by-step explanation:

The area of a rectangle is given by l\cdot w. Therefore, we can set up the following inequality:

l\cdot 16 \leq 3,003.84.

Solving this inequality, we have:

l \leq 187.74.

Therefore, the largest length Carmen's painting can be is \fbox{$187.74\:\mathrm{cm}$}.

Which of the following ordered pairs represents the solution to the system of equations below?
expeople1 [14]
<span>-3x + 2y = 2  eq (1)

  7x - 3y = 7    eq (2)

Mutiply eq (1) by 3 and eq (2) by 2:

-9x + 6y = 6

14x - 6y = 14

Add th two new equations:

-9x + 14x = 6 + 14

=> 5x = 20

=> x = 20/5

=> x = 4

Now from eq (1)

-3(4) + 2y = 2

=> 2y = 2 + 12

=> 2y = 14

=> y = 14 / 2

=> y = 7

So the ordered pair is (4,7)

Answer: option B. (4,7)

I'd say it's "convergent and doesn't have a sum"

because it's multiplying by 3 to get every new number and switching between ± after every new number. there is no sum because it's an infinite series.
