The angular velocity is 16 radians per second
<u>Solution:</u>
The angular velocity of point is given by formula:
Where,
w is the angular velocity in radians
v is the linear velocity
r is the radius
Given that diameter of wheel is 10 feet
Thus radius is 5 feet
A point on the rim of a wheel moves with a velocity of 80 feet per second
Linear velocity = v = 80 feet per second
Therefore, angular velocity is given as:
Thus angular velocity is 16 radians per second
To find the value of x we follow this:
3x+17=14
Take away 17 from both sides
3x=-3
Then divide by 3
x=-1
Answer:
532 m
step-by-step explanation:
break the figure into 3 different shapes
first one is the square at the top
L • W = A
18 • 18 = 324
the next is the triangle below it
hbb/2 = A
18b16/2 = A
144
the last is the last triangle
hbb/2 = A
8b16/2 = A
64
add them together
324 + 144 + 64
532 m
Answer:
It is not reasonable to use the line of best fit to make predictions from the data.
Explanation:
A correlation coefficient of r = 0.15 means that the goodness of fit for the data from linear regression analysis is
r² = 0.15² = 0.0225.
When r²=1, it means that correlation between the dependent and independent variable is perfect, and the dependent variable can be predicted reliably.
When r²=0, it means that there is absolutely no correlation between the dependent and independent variable.
When r²>0.9, it means that reasonable correlation exists between the dependent and independent variable.
A value of r²=0.0225 is extremely low, therefore it is not reasonable to use the line of best fit to make predictions.
Well, you see. This isn’t a question, so I’m not able to answer it. Thanks
