Answer:
the first option
Step-by-step explanation:
okay so the line passes through the 2 on the y-axis making it the y-intercept
that means you can eliminate the second and third options
now to find the slope, you can use rise over run (y2-y1/x2-x1)
3-2/3-0 = 1/3
so the slope is 1/3
all together, the equation would be:
f(x) = 1/3x + 2
so the answer is the first option
Answer:
What is centripetal acceleration?
Can an object accelerate if it's moving with constant speed? Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.
Acceleration is a change in velocity, either in its magnitude—i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant. You experience this acceleration yourself when you turn a corner in your car—if you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion. What you notice is a sideways acceleration because you and the car are changing direction. The sharper the curve and the greater your speed, the more noticeable this acceleration will become. In this section we'll examine the direction and magnitude of that acceleration.
The figure below shows an object moving in a circular path at constant speed. The direction of the instantaneous velocity is shown at two points along the path. Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation—the center of the circular path. This direction is shown with the vector diagram in the figure. We call the acceleration of an object moving in uniform circular motion—resulting from a net external force—the centripetal acceleration
i am not too sure if i am correct in this but i will give it a go. i apologise if i am incorrect. In finding the diameter the equation C/π. in finding the radius the equation is (C/π)/2
Part 1
Q2) c=650πcm
650 X π= c so d must be 650cm
Q4) c=241πcm
241 X π= c so d must be 241
Q6) c=802cm
c/π=d =802/π= 255.28cm (2DP)
Q8) c=962cm
c/π=d = 962/π= 306.21cm (2DP)
A.
Coefficient: 50
Variable: h
Constant: s
b.
50(25) + 0.20(300) + 40
1250 + 60 + 40
1350
Corinne earns $1350
c.
The coefficient would change because a coefficient is the number in front of a variable, and the number changed, not the variable or constant.
Y=7 so plug in (7)(2) -3 which equals 14-3 = 11
