Answer:
A'(5,3)
Step-by-step explanation:
First, you must understand that A(5,3) is the pre-image and that A' is what we are looking for which is the image.
With that in mind, you translate the preimage by adding or subtracting from the x and y values.
(x+4, y-3)
To find the x value of the pre-image, you will add 4 to the preimages' x value
Pre-image: A(1,6)
To find the y value, you subtract the preimages' y value by 3.
Hope this helps!
Answer:
32 days is my final answer
Step-by-step explanation:
5.28 / 12 = 0.44 per oz
7.96 / 18 = 0.4422 rounds to 0.44 per oz
technically, by rounding to the nearest cent, they are the same cost.
4 cos² x - 3 = 0
4 cos² x = 3
cos² x = 3/4
cos x = ±(√3)/2
Fixing the squared cosine doesn't discriminate among quadrants. There's one in every quadrant
cos x = ± cos(π/6)
Let's do plus first. In general, cos x = cos a has solutions x = ±a + 2πk integer k
cos x = cos(π/6)
x = ±π/6 + 2πk
Minus next.
cos x = -cos(π/6)
cos x = cos(π - π/6)
cos x = cos(5π/6)
x = ±5π/6 + 2πk
We'll write all our solutions as
x = { -5π/6, -π/6, π/6, 5π/6 } + 2πk integer k
the answer to this question is -7.25 or 7 1/4
