The perimeter of a rectangle is $98,$ and the length of one of its diagonals is $41.$ Find the area of the rectangle.
Answers
Answer:
[tex]328units^2[/tex]
Step-by-step explanation:
First off, I do want to say that you could word this more easily.
98 is the perimeter. length is 41. width is 8.
the area is length*width for rectangles.
98-41=57
57-41=16
16/2=8
8*41=328 units^2
If n'(x) = 2sin(2x) and n(0) = 0 what is the absolute maximum of n(x) on (0,2-}?
Answers
The absolute maximum of n(x) = 1 - 2 · cos 2x, whose first derivative is n(0) = 0, exists at x = 0.5π on (0, 2π]. The value of the absolute maximum is 3.
How to find the absolute maximum of a differentiable function
A function is differentiable in a given interval if and only if its derivative exists for every value of the interval. To determine the absolute maximum of n(x), we need to integrate the given function, apply first derivative and second derivative test and finally evaluate n(x).
First, we integrate n'(x) in terms of x:
n(x) = 2 ∫ sin 2x dx = 2 · (- 0.5 · cos 2x) + C = - cos 2x + C
- cos 0 + C = 0
C = 1
Then, n(x) = 1 - 2 · cos 2x.
Now we proceed to apply first and second derivative tests:
First derivative test2 · sin 2x = 0
sin 2x = 0
2 · x = sin⁻¹ 0
2 · x = π ∨ 2π
x = 0.5π ∨ π
Second derivative testn''(x) = 4 · cos 2x
n''(π) = 4 · cos 2π
n''(π) = 4
There is an absolute minimum for x = π. [tex]\blacksquare[/tex]
n''(0.5π) = 4 · cos π
n''(0.5π) = - 4
There is an absolute maximum for x = 0.5π. [tex]\blacksquare[/tex]
Finally, we evaluate n(x) for x = 0.5π to determine the absolute maximum:
n(0.5π) = 1 - 2 · cos π
n(0.5π) = 3
The absolute maximum of n(x) = 1 - 2 · cos 2x, whose first derivative is n(0) = 0, exists at x = 0.5π on (0, 2π]. The value of the absolute maximum is 3. [tex]\blacksquare[/tex]
RemarkThe statement of the question is poorly formatted and reports several mistakes, correct form is introduced below:
If n'(x) = 2 · sin 2x and n(0) = 0. What is the absolute maximum of n(x) on (0, 2π]?

An angle measures 62.4° more than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
Step-by-step explanation:
If an angle measures x degrees, the measure of its supplement is (180-x) degrees.
This means that x-62.4 = 180-x, meaning that x=121.2.
So, the angles are 121.2 and 58.8 degrees.

Which of the following is true for f(x) = –2sin(x) – 3? the range of the function is the set of real numbers negative 2 less-than-or-equal-to y less-than-or-equal-to 2. the graph of the function is the graph of f(x) = –2sin(x) shifted 3 units up. the amplitude of the function is 2. the period of the function is 4 pi.
Answers
The correct option C which is true for the given form of the sine curve f(x) = –2sin(x) – 3.
What is the range of the function?The range of a function is defined as the set of all the possible output values that are valid for the given function.
The general form of the sine curve is given as
f(x) = –2sin(x) – 3
A.
Since this curve's A is -2, its amplitude is 2 and its range is from -2 to 2. but since the D value is -3, it shifts vertically 3 units down making the range from -1 to -5. Choice A is not true.
B.
This graph is the graph of shifted 3 units down since D is negative. This choice isn't true.
C.
Because of the (minus) sign in front of the function, the function is reflected on the x-axis, but the amplitude doesn't change. Since A value is 2, the amplitude is 2. This is true.
D.
The period depends on the B value. Here, the B value is 1, so the period is normal as the parent function of a sine curve, which is, not. So this is not correct.
Therefore, C is the correct answer.

Part (a) = 47/100, Part (b) = -47/100, Part (c) = 47/100
Step-by-step explanation:
Step 1: Determine 0.47 as a fraction
0.47 can also be expressed as 47% which means that there is 47/100. We can see that there is no way that we can simplify the fraction even more so that is our final answer.
Step 2: Determine -0.47 as a fraction
0.47 can also be expressed as -47/100. We can see that there is no way that we can simplify the fraction even more so that is our final answer.
Step 3: Determine --0.47 as a fraction
Two negatives (-), means that they cancel out and cause a positive (+). For example, -1 * -1 gives us 1. Therefore it would just be like the first one which is 47/100.
Answer: Part (a) = 47/100, Part (b) = -47/100, Part (c) = 47/100

What is equation of circle?A circle is defined as round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
Since we have given that
The equation is :
[tex](x+15)^2+(y-12)^2=25[/tex]
It is the equation of circle in which center is (h,k) i.e. ( 15,12)
The general equation of circle is given by
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Here, the radius 'r' is given by
[tex]r^2=25[/tex]
[tex]r=\sqrt{25[/tex]
