Answer:
what is x?
Step-by-step explanation:
The equation of the given sine graph is gotten as; y = 4 sin [(0.4(x + 2.5)] - 1
<h3>How to find the equation of a sine graph?</h3>
We know that the general formula for equation of a sine graph is;
y = A sin [(B(x - D)] + C
where;
A is Amplitude
Period = 2π/B.
Phase Shift = -C/B.
Vertical Shift = D.
From the graph;
A = 4
B = 2π/5π = 2/5
C = -1
D = -5/2
Thus;
y = 4 sin [(0.4(x + 2.5)] - 1

Let us say that the intersection point of lines
AB and CD is called point E. The lines AB and CD are perpendicular to each
other which also means that the triangle CEB is a right triangle.
Where the line CB is the radius of the circle
while the side lengths are half of the whole line segment:
EB = 0.5 AB = 0.5 (8 ft) = 4 ft
CE = 0.5 CD = 0.5 (6 ft) = 3 ft
Now using the hypotenuse formula since the
triangle is right triangle, we can find for the radius or line CB:
CB^2 = EB^2 + CE^2
CB^2 = (4 ft)^2 + (3 ft)^2
CB^2 = 16 ft^2 + 9 ft^2
CB^2 = 25 ft^2
<span>CB = 5 ft = radius</span>
The answer to the question
The formula for point slope form is:
y − y1<span> = m(x − x</span>1<span>)
where (x1,y1) is a point on the graph and m=slope
now lets solve for the slope of our points: (1,4) (3,8)
Slope=y2-y1/x2-x1=8-4/3-1=4/2=2
Now we can plug our information into the equation
</span>y − y1 = m(x − x1)
y-4=2(x-1)
Now lets convert it to slope intercept form
y-4=2(x-1)
add 4 to both sides
y=2(x-1)+4
y=2x-2+4
y=2x+2
Now we can solve for the missing y value in (6,y) by plugging in the x value.
y=2x+2
y=2(6)+2
y=12+2
y=14
So the ordered pair would be (6,14)
Answer=14
