Answer:
170.3 miles per hour
Step-by-step explanation:
Javon won Indianapolis 500 race in 2011 with an average speed of 170.265 miles per hour. What was his average speed to the nearest tenth of a mile per hour?
From the above question, we are asked to approximate to the nearest tenth of a mile.
The number that falls under the tenth of a mile, is the number that is immediately after the decimal.
Hence, for:
170.265 miles per hour:
2 is the number in the tenth place, the number after 2 is 6, it is a number that is higher than 5. So we add 1 to 2
Therefore,
170.265 miles per hour to the nearest tenth of a mile = 170.3 miles per hour.

the correct answer is,
if you want me to solve without the parentheses then the answer would be,
Answer: 30 should be negative
Step-by-step explanation:
when having an equation like that, you must multiply -5 by 3, which equals to -15, then multiply-5 by 6 which then equals to -30. The correct equation should be -5(3+6)= -15+-30= -45
I think this should be correct, hope this helps!
Answer:
Step-by-step explanation:
2)
x^3 - 3x^2 -24x +7
Find the derivative of this: which is,
3x^2 - 6x -24
in order to find the minimum you must set it up equal to 0
0 = 3x^2 - 6x -24
0 = 3(x^2 -2x -8)
0 = (x-4)(x+2)
x= 4
x=-2
Ignore the negative 2 answer, because it is unrealistic!
Hence, velocity is: 4 cm/sec
3) and 8) aren't visible, hence, i can't answer them
9) a. (-1,1/2) is where the f is both decreasing and concave down as shown in the graph down below.
Hope this helps!
