Let's choose 43° to be our angle. We know the opposite, and want to know the hypotenuse. Sine is the trig. we use for opposite over hypotenuse.
sinθ = opposite/hypotenuse
sin(43)=27/x
We want to isolate x, so that looks like:
x = 27/sin(43)
Therefore, the value of x is 27/0.682 or ≈39.589 or F

Hello i would like help and the answer to this please; what is the nth term rule of

Paraphin [41]

Answer:

The nth term of the given sequence

$a_{n} = a_{n-1} + (2n-1)$

Step-by-step explanation:

Explanation:-

Given sequence -5,-4,-1,4,11,20,31

a₀ = -5

a₁ = a₀ +1 = -5 +1 = -4

a₂ = a₁ + 3 = -4+3 = -1

a₃ = a₂ + 5 = -1 +5 = 4

a₄ = a₃ + 7 = 4 + 7 =11

a₅ = a₄ + 9 = 11+9 = 20

a₆ = a₅ + 11 = 20+11 = 31

a₇ = a₆ + 13 = 31 +13 =44

and so on

The nth term of the given sequence

$a_{n} = a_{n-1} + (2n-1)$

Given complex numbers u and v below,what is uv u=7i V=6-i

boyakko [2]

Answer:

7 + 42i.

Step-by-step explanation:

u v = 7i(6 - i)

= 42i - 7i^2 But i^2 = -1 so:

= 42i - 7(-1)

= 7 + 42i.

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 2 cos 3θ

Nina [5.8K]

Take a quick peek at brainly.com/question/10417591
that's how you test for the y-axis, x-axis and origin

recall your symmetry identities, cos(- θ) = cos(θ)

so, simply replace θ for those values, and if the resultant function looks exactly like the original, then it has that symmetry.
