Answer: 1,384.74 units³

Step-by-step explanation: To find the volume of a cylinder, start with the formula for the volume of a cylinder.

Volume = πr²h

Notice that our cylinder has a radius of 7 units and a height of 9 units so plugging into the formula, we have (π)(7 units)²(9 units).

Start by simplifying the exponent. 7² is equal to 7 units × 7 units or 49 units² so we have (π)(49)(9). Now, 49 × 9 is 441π units³.

So the volume of the cylinder is 441π units³.

Now, remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the volume by plugging in 3.14 for π.

So we have (441)(3.14) which is equal to 1,384.74 units³.

So the value of the volume is approximately 1,384.74 units³.

volume of a cylinder: πr²h

volume = π(7²)(9) = 441π = 1385.44 un² approx.

answer: 1385.44 un² approx.

Tanzania [10]

Answer:

Negative association

Step-by-step explanation:

Positive association is when both variables increase. On a graph, the line would be going up from left to right.

No association is when the two variables don't make a line, and the data is scattered all over a graph.

There is enough information to determine this question.

That leaves B, negative association. Negative association is when one variable increases as the other decreases. On a graph, the line would be read as a line going down from left to right.

What is the coefficient of the x5y5-term in the binomial expansion of (2x – 3y)10? 10C5(2)5(3)5 10C5(2)5(–3)5 –10C5(2)5(–3)5 10C

butalik [34]

ANSWER

$10C_5(2)^{5}( - 3)^5$

EXPLANATION

The given binomial expansion is:

${(2x - 3y)}^{10}$

Compare this to

${(a + b)}^{n}$

we have a=2x , b=-3y and n=10

We want to find the coefficient of the term

${x}^{5} {y}^{5}$

This implies that, r=5.

The terms in the expansion can be obtained using

$T_{r+1}=nC_ra^{n-r}b^r$

We substitute the given values to obtain;

$T_{5+1}=10C_5(2x)^{10-5}( - 3y)^5$

$T_{6}=10C_5(2x)^{5}(3y)^5$

$T_{6}=10C_5(2)^{5}( - 3)^5 {x}^{5} {y}^{5}$

Hence the coefficient is;

$10C_5(2)^{5}( - 3)^5$
