Answer:
3 one
Step-by-step explanation:
Answer:
x =7, y = 3
Step-by-step explanation:
We substitute the value of x in terms of y (given) into the equation.
Then we solve for y and plug in the value of y back into the equation for the value of x to find x.
we conclude that the graphed equation is:
y = 4*cos(pi*x)

Which trigonometric equation is the one in the graph?</h3>
First, we can see that the graphed function is even, so we know that it wiill be a cosine.
We also can see that the maximum is 4 and the minimum is -4, so the amplitude is 4.
Then we have something like:
y = 4*cos(b*x)
To find the value of b, we can use the fact that the zeros of the function are at x = ±1/2
Then:
b*1/2 = pi/2
b = pi
Finally, we conclude that the graphed equation is:
y = 4*cos(pi*x)

Answer:
About 8.6
Step-by-step explanation:
d=(x2-x1)^2+(y2-y1)^2
8=x1 8=y1 3=x2 1=y2
(3-8)^2+(1-8)^2
(-5)^2+(-7)^2
25+49
74
take the square root and you get about 8.6
