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

= -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

A rabbit population can increase at a rapid rate if left unchecked. Assume that 10 rabbits are put in an enclosed wildlife ranch and the rabbit population triples each year for the next 5 years as shown in the table.
Part A: Let y represent the number of rabbits after x years. Which function can be used to model y as a function of x, where x is a non-negative number?
A.
y = 3(10)x
B.
y = 3(10)x-1
C.
y = 10(3)x-1

What is the image of (4, -2) after a dilation by a scale factor of centered at the
origin?
Answer:where is the number before centered so i can do it & also Write at least 20 characters to explain it well.
Step-by-step explanation:
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

Write the equation of a function whose parent function, F(x)=x+5,is shifted 3units to the right
Answer:
f'(x) = x + 2
Step-by-step explanation:
f(x) shift 3 units to the right -> f(x-3)
f'(x) = (x-3)+5 = x+2

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

A meat seller bought 250kg of meat fo GHC 224 At what price per kg should he retail it in order to make proft of 25%
Answer:
GHC1.19
Step-by-step explanation:
Given data
Mass of meat= 250kg
Cost of meat= GHC 224
cost price per kg
=224/250
=GHC 0.896 per kg
% profit= selling-cost/selling*100
let the selling price be x
25= x- 0.896/x*100
0.25= x-0.896/x
cross multiply
0.25x=x- 0.896
0.25x-x= - 0.896
0.75x= 0.896
x= 0.896/0.75
x=GHC1.19

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
