Answer:

720/1681

Step-by-step explanation:

First quadrant so everything is positive for a trig function of just the angle.  I would suggest just drawing a right triangle using tan(x)=40/9 (opp/adj). Find the hypotenuse which is sqrt(40^2+9^2)=sqrt(1600+81)=sqrt(1681)=41.  So sin(x)=40/41 and cos(x)=9/41.

Therefore sin(2x)=2sin(x)cos(x)=2(40/41)(9/41)=720/1681

Answer:-6x^{12}

Step-by-step explanation:

Open the brackets

-x is the same as -1x

(2x^{3} x -x)(3x^{8})

  • The bases will be multiplied while the powers will be multipled

-2x^{4} x 3x^{8}

  • In the law of indices(multiplication), provided the bases are equal,they are to be added.

-6 x^{4} +x^{8}

= -6x^{12}

What's the answer and how do u figure out number 5 only
shusha [124]
The length of a segment knowing the coordinates of its end points:
(x₁,y₁) and (x₂,y₂) is given by the formula:

Length = √[(x₁ - x₂)² + (y₁ - y₂)²]

T(1,4)  ;   A(4,4)  ;   P(3,0)

a) TA =√[(1-4)²+(4-4)²] → TA = 3
b) AP  =√[(4-3)²+(4-0)²] →AP  = √17 = 1.123
c) TP =√[(1-3)²+(4-0)²] → TA = √20 =  4.472

Perimeter = TA + AP + TP = 8.60
