Answer:
The correct options ares:
b) y = -2sin2x
c) y = -2cos(2 x - π/2)
d) y = 2sin2( x - π/2)
Step-by-step explanation:
As we can see in the graph, when x = 0 then y = 0.
Simply substitute x=0 in each equation.
a) y = 2cos2(x • π/2)
for (0,0)
y = 2
False
b) y = -2sin2x
for (0,0)
y=0
True
c) y = -2cos(2 x - π/2)
for (0,0)
y=0
True
d) y = 2sin2( x - π/2)
for (0,0)
y=0
True,
(We can also find the solution by using y= Asin(Bx+C) and y = Acos(Bx+C), we'll find that except equation a, all other equations have same amplitude, horizontal shift, period and vertical shift)

Math I NEED HELP LOOK AT THE IMAGE ALGEBRA IS KILLING ME
Answer:
Based on the given information in the problem, 18 is found to be 75% of 24.
Step-by-step explanation:
In order to solve this problem, we must first know what we are being asked to do. In the problem, we are asked to find what percent of 24 is 18. We can find this percentage by dividing. We will divide 24 by 18.
18 ÷ 24 = 0.75
Now, we multiply this number by 100 to get the percent.
0.75 × 100 = 75
So, 18 is 75% of 24.
Answer:
the correct answer would be 75%

In which triangle is the measure of the unknown angle, x, equal to the value of sin–1(StartFraction 5 Over 8.3 EndFraction)? A right triangle is shown. The length of the hypotenuse is 8.3 and the length of another side is 5. Angle x is between those sides. A right triangle is shown. The length of the hypotenuse is 8.3 and the length of another side is 5. Angle x is opposite to side with length 5. A right triangle is shown. The length of the hypotenuse is 5 and the length of another side is 8.3. The angle opposite to side with length 8.3 is x. A right triangle is shown. The length of 2 sides are 8.3 and 5. The angle opposite to side with length 5 is x.
Question:
In which triangle is the measure of the unknown angle, x, equal to the value of [tex]sin^{-1}(\frac{5}{8.3})?[/tex]
- A right triangle is shown. The length of the hypotenuse is 8.3 and the length of another side is 5. Angle x is between those sides.
- A right triangle is shown. The length of the hypotenuse is 8.3 and the length of another side is 5. Angle x is opposite to side with length 5.
- A right triangle is shown. The length of the hypotenuse is 5 and the length of another side is 8.3. The angle opposite to side with length 8.3 is x.
- A right triangle is shown. The length of 2 sides are 8.3 and 5. The angle opposite to side with length 5 is x.
Answer:
The length of the hypotenuse is 8.3 and the length of another side is 5. Angle x is opposite to side with length 5.
Step-by-step explanation:
Given
[tex]x = sin^{-1}(\frac{5}{8.3})[/tex]
Required
Determine the triangle that illustrates the given parameters
From the list of given options, we understand the the triangle is a right angled triangle.
Provided that
[tex]x = sin^{-1}(\frac{5}{8.3})[/tex]
Take sin of both sides
[tex]sin\ x = sin(sin^{-1}(\frac{5}{8.3}))[/tex]
[tex]sin\ x = \frac{5}{8.3}[/tex]
From trigonometry; we understand that
[tex]sin\ x = \frac{Opp}{Hyp}[/tex]
Where Opp is the Opposite and Hyp is the Hypotenuse of the triangle
By comparison, this means that
[tex]Opp = 5\\Hyp = 8.3[/tex]
From the list of given options;
The option that best fit the illustration above is option B;
Because of the following;
1. The length of the hypotenuse is 8.3
2. The length of another side is 5.
3. Angle x is opposite to side with length 5.
See attachment for the actual triangle;

Answer:
3.4
Step-by-step explanation:
If we look at the top left triangle and the triangle with x, we notice that they are similar (since they have a 57° and a right angle). This means that 4 / 1 = x / 0.84, which means that x = 3.4.

The statement tan theta -12/5, csc theta -13/5, and the terminal point determined by theta is in quadrant 2."
Answer:
Answer C:
Cannot be true because [tex]csc(\theta)[/tex] is greater than zero in quadrant 2.
Step-by-step explanation:
When the csc of an angle is negative, since the cosecant function is defined as:
[tex]csc(\theta)=\frac{1}{sin(\theta)}[/tex]
that means that the sin of the angle must be negative, and such cannot happen in the second quadrant. The sine function is positive in the first and second quadrant.
Therefore, the correct answer is:
Cannot be true because [tex]csc(\theta)[/tex] is greater than zero in quadrant 2.

Answer:
Last choice. √14/√14
Step-by-step explanation:
Multiplying by the reciprocal of the denominator would "cancel" the denominator, but To rationalize the -√14, you have to multiply it by √14 and you need an equivalent of 1 to keep the terms equal. So the numerator and denominator have to be multiplied by the same thing.

If the nth term of a number sequence is n squared+2n find the first 3 terms and the 10th term
Answer:
First 3 terms are 3, 8, 15.
10th term = 120.
Step-by-step explanation:
an = n^2 + 2n
a1 = 1^2 + 2*1 = 3
a2 = 2^2 + 2*2 = 8
a3 = 3^2 + 2*3 = 15.
a10 = 10^2 + 20 = 120.

(-42.65,4.8) and (2.65,3.6) what is the slope
Answer:
-4/151
Step-by-step explanation:
We can find the slope by
m = (y2-y1)/*x2-x1)
= (3.6 - 4.8)/(2.65 - -42.65)
= (3.6 - 4.8)/(2.65 +42.65)
= -1.2 / 45.3

A.-30
B. -6
C.6
D. 30
Answer:
C
Step-by-step explanation:
Noting that
+ (- ) is equivalent to subtraction
- (- ) is equivalent to addition
Given
13 + (- 12) - (- 5)
= 13 - 12 + 5
= 1 + 5
= 6 → C
Answer:
C) 6
Step-by-step explanation:
13 + (-12) - (-5) = 13 + (-12) + 5
= 1 +5
= 6
13 & (-12 ) have different sign, so subtract and put the sign of the greater number's sign.

Find the x- and y-intercept of the line x+4y=36
Answer:
x=36
y=9
Step-by-step explanation:
Plug in 0 for x to find the y-intercept
0 + 4y = 36
4y = 36
y = 9
y-intercept (0, 9)
Plug in 0 for y to find the x-intercept
x + 4(0) = 36
x = 36
x-intercept (36, 0)
Graph g(x), where f(x) = 4x – 2 and g(x) = f(x + 1).
Answer:
Please see attached image
Step-by-step explanation:
We start by finding the actual algebraic expression for g(x):
g(x) = f(x+1) = 4(x+1) - 2 = 4 x + 4 - 2 = 4 x + 2
Then we plot this function on the x-y plane using two or three pairs solution to the equation, like:
for x = 0 g(x) = 2
for x = 1 g(x) = 6
for x = -1 g(x) = -2
and joining them with a line.

Answer:
This is really weird. None of them seem to be right.
For the first one, it says that -7.5 is greater than or equal to -6.4, which is not true. -7.5 is less than -6.4. The next one is the only one that makes a true comparison, but I don't agree with the "or equal to" part. -7/8 cannot be equal to 7/8. The next one is false, -4 is greater than -8. Finally, the last one is incorrect as well because -4.2 is less than -3.6.
However, if I had to choose one, I'd choose the second option. It's the closest to being correct.

Choose the graph that displays the solution to the system of equations.
x = y - 2
y-8 =
2
Answer:
The first graph is the solution to:
x = y - 2 (blue line)
y-8 = -1/2x (red line)
where the solution is (4,6)
The second graph is the solution to:
x = y - 2 (blue line)
y-8 = -2x (red line)
where the solution is (2,4)
Step-by-step explanation:
The second equation is not clear. From the figures, the possible functions are: y-8 = -1/2x and y-8 = -2x.

y=.12x+20
Step-by-step explanation:
The flat rate for the ride is $20, so that will be added on no matter how far you go. The distance is actually extra information in this problem, as it doesn't actually ask for you to solve, so ignore the 50 miles from the airport. It is $0.12 per mile, meaning that actually does depend on the number of miles travelled, so it must be the x coefficient. This leaves you with y=.12x+20.

Step-by-step explanation:
you cut it into shapes so one's a square, one's a rectangle, and one's a triangle.
area for square is b times h or b^2
area for rectangle is b times h
area for triangle is 1/2b times h
once u get this u add them all
a for s= 4 times 4 which is 16
a for r = 4 times 2 which is 8
a for t = 1/2 4 times 2 which is 4
