sketch a graph and write an equation for a sinusoidal function that has a period of 12 seconds, a maximim height of 8ft and a minimim height of -4 ft. At a time t=0, the function's height is at its highest point.
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
Which fraction is equivalent to
-3/2?
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

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)?
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.

100 cm = 1m
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?
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.
the product of two consecutive integers is 5 more than three times the larger integer. Find the larger integer. please help!
Answer:
x = 5 or -1
Step-by-step explanation:
let larger integer be: x
the smaller integer is: x-1
(x)(x-1)=5+3(x)
x^2-x-5-3x=0
x^2-4x-5=0
x = 5 or -1

15.it will take 88 minutes to add 16 seats.
It will take 104.5 minutes to add 19 seats.
Step-by-step explanation:
Let m represent number of minutes.
We have been given that an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle to a rate of 2 seats in 11 minutes.
We will use proportions to solve our given problem.
To find the time taken to add 16 seats, we will in our proportion as:
Therefore, it will take 88 minutes to add 16 seats.
To find the time taken to add 19 seats, we will in our proportion as:
Therefore, it will take 104.5 minutes to add 19 seats

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

Answer:
-24
Step-by-step explanation:
We can simplify this to ...
b^2 +3(b -b^2) -2a
= b^2 +3b -3b^2 -2a
= -2b^2 +3b -2a . . . . . . . simplified form
This can be made easier for evaluation by factoring out b.
= (-2b +3)b -2a
Using the given values, this is
= (-2(4) +3)(4) -2(2)
= (-5)(4) -4
= -24 . . . . value of the expression

Give your answer correct to 1 decimal place,
You must show all your working,
On the same line as your final answer you must write "to 1 decimal place".
Answer:
Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:
x = 8.3

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.
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
