Find the difference between 7 1/2 and 2 3/4

Mathematics
1 answer:
NNADVOKAT [17]3 years ago
3 0

Answer:

4\frac{3}{4} or 4.75

Step-by-step explanation:

first we're going to convert the number into improper fractions.

7\frac{1}{2}= \frac{15}{2} and 2\frac{3}{4}= \frac{11}{4}

For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply \frac{15}{2}x2, it'll equal the same number.

So now we have \frac{30}{4}-\frac{11}{4}, 30-11= 19.

\frac{19}4} simplified is, 4\frac{3}{4}.

As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.

I hope this helps you!

Step-by-step explanation:

4-8= -4 (-2-6t) if t=-1 instead of t besides 6 put -1 multiplier it which it will become positive.

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the curves about the given
rewona [7]

Answer:

5.81

Step-by-step explanation:

The method of cylindrical shells uses this formula:

\int\limits^a_b {2 \pi * shellRadius * shellHeight} \, dx

It integrates the pieces of area in the region.

In this case:

2 \pi * \int\limits^2_0 {x * cos(\frac{\pi}{4} * x)} \, dx

Integrating by computer:

2*\pi*(\frac{4}{\pi^2}*(\pi*x*sin(\frac{\pi}{4}*x) + 4*cos(\frac{\pi}{4}*x)))

Evaluating between 0 and 2

2\pi * (\frac{4}{\pi^2}*(\pi*2*sin(\frac{\pi}{4}*2) + 4*cos(\frac{\pi}{4}*2)) - \frac{4}{\pi^2}*(\pi*0*sin(\frac{\pi}{4}*0) + 4*cos(\frac{\pi}{4}*0))) = 5.81
