Answer:
1. you dont add before you multiply
2 they didnt do the parenthesis first...which was their mistake
Step-by-step explanation:
Use the shell method. The volume is
<em>V</em> = 2<em>π</em> ∫₅⁸ (<em>x</em> - 5) <em>x</em> ² d<em>x</em>
<em>V</em> = 2<em>π</em> ∫₅⁸ (<em>x</em> ³ - 5<em>x</em> ²) d<em>x</em>
<em>V</em> = 2<em>π</em> (1/4 <em>x</em> ⁴ - 5/3 <em>x</em> ³) |₅⁸
<em>V</em> = <em>π</em>/6 (3<em>x</em> ⁴ - 20<em>x</em> ³) |₅⁸
<em>V</em> = <em>π</em>/6 ((3 × 8⁴ - 20 × 8³) - (3 × 5⁴ - 20 × 5³))
<em>V</em> = 891<em>π</em>/2
1. 28/15 as a decimal is <span>1.86666666666667
2.
</span><span>the number is divisible by 3. </span>
<span>Additionally, we know 120,000 is divisible by 3, 18,000 is divisible by 3, 420 is divisible by 3, and 15 is divisible by 3.
I hope this helps! I didn't do the last one my friend did but he thinks it's right. Please correct me if wrong.</span>
Answer:
The slope is -1
Step-by-step explanation:
y = -x +8
This equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -1
