URGENT! What is the equation of this graph? It is a cosine graph whose equation will fit into terms of y=acos(b(x-c))+d
Answer:
y=-5cos(pi/8(x+2))-21
Step-by-step explanation:
y=acos(b(x-c))+d
Let's find the max and then the min first. We are aiming to find the amplitude, a, which is the half the distance from the max to the min.
Max is y=-16
Min is y=-26
a=(-16--26)/2=-8--13=5
a could also tell us if y=cos(x) has been reflected about the x-axis if it is -5, which it looks like it has considering cos(0)=1 not -1.
I'm looking at the point (-2,-26) which is the lowest point of our curve and comparing it to our high point of (0,1) on y=cos(x).
So far we have, y=-5cos(b(x-c))+d.
Let's look at d, vertical shift. The average of our max and min is (-26+-16)/2=-13-8=-21.
So our vertical shift is d=-21.
So now equation is y=-5cos(b(x-c))+-21.
Now since we are using (-2,-26) as our (0,1) point on y=cos(x) then c=-2.
So now equation is y=-5cos(b(x--2))+-21
Now we are going to plug in a point haven't mentioned to find b. So looking at graph I will use (6,-16).
-16=-5cos(b(6--2))+-21
Add 21 on both sides:
5=-5cos(b(6--2))
Divide both sides by -5:
-1=cos(b(6--2))
Simplify inside:
-1=cos(b8)
Multiplication is commutative:
-1=cos(8b)
8b=pi * cos(pi)=-1
b=pi/8
The equation is
y=-5cos(pi/8(x--2))+-21
Simplify:
y=-5cos(pi/8(x+2))-21

QUICK! WHAT IS THIS ANSWER?
Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
a)we want to expand the following expression:
[tex] \displaystyle - \frac{1}{4} ( - 8x + 12y)[/tex]
well to do so we consider distributive property thus distribute:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)[/tex]
reduce fraction which yields:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)[/tex]
simplify Parentheses:
[tex] \displaystyle \boxed{ 2x - 3y}[/tex]
b)in the expression there's a common factor of 4 therefore factor it out:
[tex] \displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}[/tex]
A biased 3-coloured spinner was spun 240 times. It landed on Red n times, on Orange 3n times and on Yellow 8n times.
If you spin this spinner 1000 times, how many times do you expect it to land on Red?
(Hint: Find n first)
Answer:
83 times.
Step-by-step explanation:
n + 3n + 8n = 240
12n = 240
n = 20.
So we have 20 reds in 240 spins
So by proportion the number expected in 1000 spins
= 20 * 1000/240
= 1000/12
= 83 1/3
So its 83 reds.

Step-by-step explanation:
Angle UQN = Angle QNM, in alternate interior angle relation so Angle QNM will be x.Now we know that the angles inside a triangle sum up to give 180⁰,that is x+x+42⁰=180⁰2x+42⁰=180⁰
2x=180⁰- 42⁰
2x= 138⁰
x= 138⁰/2
x= 69⁰
Find the value of x in each case:
Answer:
x=36
2x=72
4x=144
Step-by-step explanation:
Remember that the sum of all the inside angles of a triangle = 180
so angle E is 180-2x
and angle F is 180-4x
If you add angles E, F, and G, they need to add to 180.
substituting, we get 180-2x + 180-4x + x = 180.
Simplifying this, we get 180-5x = 0
and x=180/5 = 36
so if x=36, then 2x=72 and 4x=144
Answer:
36
Step-by-step explanation:
The angles of the triangle are going to be, (x), (180-2x), (180-4x)
and since the sum of the angles of a triangle is 180, then:
x + (180-2x) + (180-4x) = 180
-5x + 360 = 180
-5x = 180 - 360
-5x = -180 (Multiply both sides by -1)
5x = 180
x = 36
So, the three angles will be: 36, 144 and 72
Cho hình thang ABCD(AB//CD) có AB=40cm CD=80cm BC =50cm AD=30cm cmr ABCD là hình thang vuông
From A draw AG // BC cuts CD at WO
We have: Trapezoid ABCD (assumption)
⇒ AB // CD
⇒ AB // GC (because G ∈ CD)
Considering quadrilateral ABCG, there are:
AB // GC (proven above)
AG // BC (assumption)
⇒ Quadrilateral ABCG is a parallelogram
⇒ AB = GC = 40 cm
AG = BC = 50 cm
We have: DG = CD - GC (because G ∈ CD)
DG = 80 - 40
⇒ DG = 40(cm)
Considering ΔAGD, there are:
AG2=AD2+DG2AG2=AD2+DG2
502=302+402⇒502=302+402
⇒502=900+1600⇒502=900+1600
502=2500⇒502=2500
⇒502=502⇒502=502
⇒ AGD square at D
⇒ Trapezoid ABCD is a square trapezoid

Which graph represents the system of equations?
y = -2x + 1
y = -2x^2 + 1
Plzz help, this locks tonight!
The graph of the system of equations:
y = -2x + 1y = -2x^2 + 1Is the one in the bottom right.
Which graph represents the system of equations?Here we want to see which graph represents the system of equations:
y = -2x + 1y = -2x^2 + 1So we have a linear equation that crosses the y-axis at y = 1, and a parabola that crosses the y-axis also at y = 1 (you can verify that by evaluating both equations in x = 0).
Only with that, we can conclude that the correct graph for the system of equations is the last one (bottom right graph)

If the two legs of a right triangle are 15 and 20, how long is the hypotenuse?
Answer:
25
Step-by-step explanation:
To solve this problem, you can use the pythagorean theorem, which is a^2 + b^2 = c^2 where a and b are legs and c is the hypotenuse. We can plug in the values of 15 and 20, and solve for c:
15^2 + 20^2 = c^2
225 + 400 = c^2
625 = c^2
c = 25
This means the hypotenuse is 25.
Is (5, 0) a solution to the equation y = x + 5?
Guys I need help
Answer:
no
Step-by-step explanation:
substitute the x- coordinate 5 into the equation and if the result is equal to the y- coordinate 0 then it is a solution
y = 5 + 5 = 10 ≠ 0
Then (5, 0 ) is not a solution to the equation
If you divide any natural number n by 4, you get a remainder r.
Find r if n=13; 34; 43; 100. What is the domain of the
function? What is the range?
Given:
If you divide any natural number n by 4, you get a remainder r.
To find:
The values of r if [tex]n=13;34;43;100[/tex]. Also find the domain and range.
Solution:
It is given that any natural number n by 4, you get a remainder r.
[tex]\dfrac{n}{4}=q+\dfrac{r}{4}[/tex]
Where, n is a natural number, q is quotient, r is the remainder.
For [tex]n=13[/tex],
[tex]\dfrac{13}{4}=3+\dfrac{1}{4}[/tex]
So, [tex]r=1[/tex].
For [tex]n=34[/tex],
[tex]\dfrac{34}{4}=8+\dfrac{2}{4}[/tex]
So, [tex]r=2[/tex].
For [tex]n=43[/tex],
[tex]\dfrac{43}{4}=10+\dfrac{3}{4}[/tex]
So, [tex]r=3[/tex].
For [tex]n=100[/tex],
[tex]\dfrac{100}{4}=25+\dfrac{0}{4}[/tex]
So, [tex]r=0[/tex].
Therefore, the required value are [tex]r=1,2,3,0[/tex] if [tex]n=13;34;43;100[/tex] respectively.
The domain of the function is [tex]\{13,34,43,100\}[/tex] and the range of the function is [tex]\{1,2,3,0\}[/tex].
