The answer is D you have to find the value of c
Hello from MrBillDoesMath!
Answer:
P = ( sqrt(2)/2), sqrt(2)/2 )
Discussion:
The circle has a radius of 1 as passes it passes through the point (1,0). P makes an angle of 45 degrees with respect to the positive x axis, so by the Pythagorean theorem (or equivalently, trigonometry),
P = (x,y) = ( [email protected], [email protected]) = (1 cos(45), 1 sin(45)) =
( sqrt(2)/2), sqrt(2)/2)
Thank you,
MrB
Step-by-step explanation:
=2(6×+7)(7×-4)
=2(+42)(-32)
=2×+42×-32
=84×-32
=-2688
Answer:
The chord is 10cm from the center of the circle
Step-by-step explanation:
Here, we want to find the distance of the chord from the center of the circle
A line from the center to the chord will
divide the chord into two parts
each will have a measure of 48/2 = 24 cm
So now we have a right/angled triangle with hypotenuse of 26
To find the height, we use Pythagoras’ theorem which states that the sum of the squares of the other sides equal the square of hypotenuse
h ^2 + 24^2 = 26^2
h^2 = (26-24)(26+24)
h^2 = 100
h = square root of 100, which is 10
