Answer: $11.60
Step-by-step explanation:
To find the temperature after 5 minutes you will find the rate of change that occurred in the first minute and apply that to the next 5 minutes.
The temp drops 13 degrees (20-7) after 1 minute, so it will drop 13 more minutes the next minute (7-13= -6 degrees)
Another 13 the next minute (-6-13=-19), BUT it will not drop below the actual air temp.
The thermometer should be at -15 degrees after 5 minutes.
Answer:
19.2
Step-by-step explanation:
(cos^-1)(17/18)
From the equations given above, you can graph them by the slope and the y-intercept. I will be solving this by substitution method. It will be giving the same values as with graphing. We do as follows:
-2x + 30 <span>= -x + 21
-x = -9
x = 9
y = -9+21 = 12
Hope this helps. Have a nice day.

Answer:
sin²Ф
Step-by-step explanation:
I doubt that you actually meant "cos 0" ... that has a value of 1.
If you meant (1-cos Ф)(1+cos Ф), then this product is 1 - cos²Ф.
That, in turn, is equal to sin²Ф
