Maru [420]

a1 = 54

a2 = (1/3)a1 = (1/3) * 54 = 18

a3 = (1/3)a2 = (1/3) * (1/3)a1 = 18/3 = 6

etc.

y = 54(\dfrac{1}{3})^{x - 1}

If a rectangle has side lengths 5x-y and x+4y what would be the area and perimeter of the rectangle?
Dafna1 [17]

Answer:

<em>Answer is</em><em> </em><em>given</em><em> </em><em>below with explanations</em><em>. </em>

Step-by-step explanation:

given \:  \: l = 5x - y \: and \: \:  b = x + 4y \\ area \: of \: rectangle \:= l \times b \: sq.units \\  = (5x - y)(x + 4y) \\  = 5 {x}^{2}  + 20xy - xy - 4 {y}^{2}  \\  = 5 {x}^{2}  + 19xy - 4 {y}^{2}  \\ perimeter \: of \: rectangle \\  = 2(l + b) \\  = 2(5x - y + x + 4y) \\  = 2(6x + 3y) \\  = 12x + 6y

Find the simplified quotient of y^2+y/y^2-2y/4y+4/y^2-4y+4
babunello [35]

Answer:

y4 - 8y3 + 8y2 + 2y + 8

 —————————————

           2y2          

Step-by-step explanation:

Step  1  :

            4

Simplify   ——

           y2

Equation at the end of step  1  :

            y       y       4

 (((((y2)+————)-((2•—)•y))+——)-4y)+4

          (y2)      4      y2

Step  2  :

           y

Simplify   —

           4

Equation at the end of step  2  :

            y       y       4

 (((((y2)+————)-((2•—)•y))+——)-4y)+4

          (y2)      4      y2

Step  3  :

            y

Simplify   ——

           y2

Dividing exponential expressions :

3.1    y1 divided by y2 = y(1 - 2) = y(-1) = 1/y1 = 1/y

Equation at the end of step  3  :

          1  y2   4

 (((((y2)+—)-——)+——)-4y)+4

          y  2   y2

plz mark me as brainliest :)

Please Help!!<br><br> Write in exponential form.
Nimfa-mama [501]

Answer:

C, 5e^{i(5\pi/3)

Step-by-step explanation:

Euler's formula:

e^{ix}=\cos{x}+i\sin{x}

Looking at the expression in the parentheses, your x is explicitly given to you as 5\pi/3, so using Euler's formula:

5\left(\cos\frac{5\pi}{3}+i\sin{\frac{5\pi}{3} })=5e^{i(5\pi/3)

Which is C.
