A farmer is creating a rectangular garden such that the length is four times the width. The
area of the garden is 2077 square feet. Write and solve an equation to determine the width
of the garden, to the nearest tenth of a foot.

Answers

Answer:

Width of the garden = 22.8 foot

Step-by-step explanation:

Area of the rectangular garden = 2077 square feet.

Let

Width of the garden = x

Length of the garden = 4x

Area of a rectangular garden = length × width

2077 = 4x * x

2077 = 4x²

x² = 2077/4

x² = 519.25

find the square root of both sides

x = √519.25

x = 22.787057730211

To the nearest tenth of a foot.

x = 22.8 foot

Width of the garden = 22.8 foot

Verify the identity sin^2x = cos^2x sec^2x-cos^2x

Answers

Answer:

Step-by-step explanation:

The right side of the identity

[tex]cos^{2} x sec^{2} x - cos^{2} x\\= cos^{2} x (\frac{1}{cos^{2} x} ) - cos^{2} x\\= 1 - cos^{2} x\\= sin^{2} x[/tex]

which is the same as the left side of the identity

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 9 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?​

Answers

Answer:

The perimeter of the triangle can be expressed as 5x + 18.

Step-by-step explanation:

Perimeter of an object is the sum of the length of its sides.

For the required triangle, we have;

length of the base = x

length of the second side = 3x + 9

length of the third side = x + 9

Perimeter of the triangle = length of the base + length of the second side + length of the third side

                                        = x + (3x + 9) + (x + 9)

                                        = x + 3x + 9 + x + 9

                                        = 5x + 18

The perimeter of the triangle can be expressed as 5x + 18.

If the expression 76.56 is written as 6k, what is the value of k?

Answers

Answer:

6k=76.56

k = 12.76

Step-by-step explanation:

the total value of 76.56 is represented as 6k

this means we equate 6k to 76.56

i.e 6k = 76.56

dividing both sides by 6

we have, k = 12.76

parallelogram has vertices at (4,4), (7,4), (5,2), and (2, 2). The parallelogram is translated 7 units down and reflected across the y-axis. What are the coordinates of the first point of its image (4,4)?​

Answers

Answer:

Step-by-step explanation:

So we move the parallelogram down 7 units and get the coordinates: (-3,4) (0,4) (-2,2) (-5,2)

Then the equation for reflecting across the y-axis is (x,y) ---> (-x,y) Then I think you can solve it from there. Just take the x points and make them the opposite charge.

Which fraction is equivalent to
-3/2?

Answers

Answer:

-1 1/2 if you need a mixed number then choose -1 1/2

Answer: There are many possible fractions, here is all of them.

-3/2 = -6/4 = -9/6 = -12/8

= -15/10 = -18/12 = -21/14 = -24/16

= -27/18 = -30/20 = -33/22 = -36/24

= -39/26 = -42/28 = -45/30 = -48/32

= -51/34 = -54/36 = -57/38 = -60/40

= -63/42 = -66/44 = -69/46 = -72/48

= -75/50 = -78/52 = -81/54 = -84/56

= -87/58 = -90/60 = -93/62 = -96/64

= -99/66 = -102/68 = -105/70 = -108/72

= -111/74 = -114/76 = -117/78 = -120/80

= -123/82 = -126/84 = -129/86 = -132/88

= -135/90 = -138/92 = -141/94 = -144/96

= -147/98 = -150/100 = -153/102 = -156/104

= -159/106 = -162/108 = -165/110 = -168/112

= -171/114 = -174/116 = -177/118 = -180/120

= -183/122 = -186/124 = -189/126 = -192/128

= -195/130 = -198/132 = -201/134 = -204/136

= -207/138 = -210/140 = -213/142 = -216/144

= -219/146 = -222/148 = -225/150 = -228/152

= -231/154 = -234/156 = -237/158 = -240/160

= -243/162 = -246/164 = -249/166 = -252/168

= -255/170 = -258/172 = -261/174 = -264/176

= -267/178 = -270/180 = -273/182 = -276/184

= -279/186 = -282/188 = -285/190 = -288/192

= -291/194 = -294/196 = -297/198 = -300/200

Answers

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

The amplitude of the function is half the difference between the maximum and minimum:

  A = (8 -(-4))/2 = 6

The multiplier of t is (2π)/period, so is ...

  B = (2π)/12 = π/6

The vertical offset is the average of the minimum and the maximum:

  D = (8 +(-4))/2 = 2

The peak is at t=0, so the cosine function is the appropriate choice.

__

Then the function is ...

  f(t) = Acos(Bt) +D

  f(t) = 6cos(πt/6) +2
