Answer:
sin 90
Step-by-step explanation:
cos (0)
Using the unit circle, we know that cos 0=1
sin 1 and cos 1 are not equal to 1
sin 90 =1
tan 90 = sin 90/ cos 90 = 1/0 =undefined
The final equation is (x-5)^2 + (y+4)^2 = 10^2.
Hopefully this'll help you!
Answer: 525 cycles per second.
Step-by-step explanation:
The equation for inverse variation between x and y is given by :-
(1)
Given : The length of a violin string varies inversely with the frequency of its vibrations.
A violin string 14 inches long vibrates at a frequency of 450 cycles per second.
Let x = length of a violin
y= frequency of its vibrations
To find: The frequency of a 12 inch violin string.
Put
in equation (1) , we get
Divide both sides by 12 , we get

Hence, the frequency of a 12 inch violin string = 525 cycles per second.
Answer:
y = 3/2x + 1
Step-by-step explanation:
find the slope: goes up 9 over 6 => 9/6 = 3/2
the +1 is because the y intercept is not at (0, 0), it's at (0, 1)
I graphed it and got the same graph :)
