Answer:
100 beats per minute
Step-by-step explanation:
If it takes 28.8 secs for the piano to play 48 beats, then it would take 60 secs (1 minute) to play x number of beats.
To find the value of x, which is the number of beats the piano makes per minute, let's set the proportion as shown below:
28.8 secs = 48 beats
60 secs = x beats
Cross multiply
28.8*x = 60*48
28.8x = 2,880
Divide both sides by 28.8
x = 2,880/28.8
x = 100
✅Thus, if the Piano plays 48 beats in 28.8 secs, therefore, the tempo of the piano in beats per minute would be 100 BPM
Answer:
(cosx+2)(cosx-1)
Step-by-step explanation:
cos x - sin²x - 1
sin²x = 1- cos²x
plug in
cos x - (1- cos²x) - 1 = cos x - 1 + cos²x - 1 = cos²x + cos x - 2
factor cos²x + cos x - 2
(cosx+2)(cosx-1)

The chart shows the damage index to a head gasket on trucks according to ambient temperature. Draw a scatterplot of the data.
Which equation is closest to the line of best fit?
A) y = 14 x - 2/3
B) y = -14 x + 2/3
C) y = -2/3 x + 14
D) y = 2/3 x - 14
If we take a look at the data presented in the chart we can see the damage that the head gasket on truck suffers according to the ambient temperature. The correct answer is letter C) because there is a negative slope that is less than one and the y-intercept begins 14 units up the y-axis.
I hope this helps, Regards.
Answer:
C. I would recommend that he does not go as lower temperatures have a strong negative correlation, therefore the lower the temperature the more damage is caused
Step-by-step explanation:
The correct answer is I would recommend that he does not go as lower temperatures have a strong negative correlation, therefore the lower the temperature the more damage is caused. For temperatures below 19 degrees Celsius the scatterplot forms a negative correlation.
