Answer:

4.9 units

Step-by-step explanation:

We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.

a being 4, and b being 3.

We need to use the Pythagorean Theorem to solve this.

$a^2 + b^2 = c^2$

we can rewrite this as;

$4^2 + 3^2 = c^2\\$

Calculation time

15 + 9 = c

c = 24

Now we find the square root of each equation to determine what $c^2$ is.

$\sqrt{15}+\sqrt{9}=\sqrt{24}$

4 + 3 = 4.89897948557

Let's round that to the nearest tenth.

4.9 units

Hope this helped :)

Find the 5th term of the expansion of ( 6x + 6y)^11

Elodia [21]

The 5 th term of the given expression is 330 $(6x)^{7}( 6y)^{4}$ .

Step-by-step explanation:

Given,

$(6x+6y)^{11}$

To find the 5th term of the given expression.

Formula

In a binomial series $(a+b)^{n}$ , the r th term is = nC(r-1) $a^{n-r-1} b^{r-1}$ , where,

nC(r-1) = $\frac{n!}{(r-1)!(n-r+1)!}$

Now,

Putting, n=11, r = r, a=6x and b=6y we get,

5 th term = 11C4 $(6x)^{7}( 6y)^{4}$

= $\frac{11!}{4!7!}$ $(6x)^{7}( 6y)^{4}$

= $\frac{11X10X9X8X7!}{7!X4X3X2X1}$ $(6x)^{7}( 6y)^{4}$

= 330 $(6x)^{7}( 6y)^{4}$

Here is the answer.
