Answer:
Center
Step-by-step explanation:
A diameter is a line segment whose endpoints are on a circle. It is a special type of chord because it must contain the center of the circle.
Answer:
Vertical angle=9.5°
Time to reach maximum height = 1.24seconds
Step-by-step explanation:
The maximum distance x is reached when rope swings to a maximum height, maximum height is gotten from the equation KE= 1/2MU^2 = MgH = MgL= Mgl(1- cos theta.
Where theta is the vertical angle, U=2m/s and L= 15m
2gl -2glcostheta=U^2
2gl U^2=2gl cos theta
But theta= Acos(1- U^2)/2gl
Acos(1-/(2×9.8×15)
Theta =9.5°
Maximum height li given by
Lsintheta
But X= UxT
T=X/UX= Lsintheta/U = 15sin9.5 /2 =1.24seconds

Answer:
y = -3x + 7
Step-by-step explanation:
Write the equation of a line using <u>slope-intercept form</u> which uses the equation y = mx + b.
This is what each letter (variable) means:
"m" is the slope of the line (how steep it is).
"b" is the y-intercept (when the line hits the y-axis).
"x" and "y", when the equation is still balanced, is a point on the line.
To write the equation, we need the slope "m" and the y-intercept "b", which is given in the question.
Substitute the numbers into the equation y = mx + b.
y = -3x + 7
