Answer:
RPM 1388.889
Horsepower 366.802
Step-by-step explanation:
We do not need to solve the equation for y = 0, which is nice. We can go directly to finding the maximum.
The maximum or minimum of ax^2+bx+c is always at x=-b/2a
with b = 25/45 and a = -1/5000 we get
x = -25/45 / (-2/5000) = 5/9 * 2500 = 12500/9 ≈ 1388.889
Now we only need to put that x into the equation (ideally in form of 12500/9 for accuracy) and we get the horsepower of ~366.802
Volume of the first dwarf planet (r₁ = 832 mi):
Volume of the second dwarf planet (r₂ = 829 mi):
So difference between the volumes is:
or if we want exact value (we use (a³-b³) = (a-b)(a²+ab+b²) ):
Answer:40
Step-by-step explanation:
Answer:
<em>B) Victor</em>
Step-by-step explanation:
<em>A positive value for r implies a positive linear correlation, while a negative value for r implies a negative linear correlation. The
</em>
<em>closer |r| is to 1, the stronger the correlation, and the stronger the correlation, the more reasonable the data model. Since |–0.91| =
</em>
<em>0.91, |0.73| = 0.73, |–0.44| = 0.44, and |0.88| = 0.88, the person with the most reasonable model for his or her data is</em><em> B) Victor!</em>
Hope this helps, have a good day. c;
