Answer:

D. $\frac{{7}^{11} }{ {4}^{11} }$

Step-by-step explanation:

$( \frac{7}{4}) {}^{11} = \frac{7 {}^{11} }{4 {}^{11} }$

Since we are multiplying an exponential number to a fraction the answer is going to be

$\frac{7 {}^{11} }{4 {}^{11} }$

Hope this helps ❤❤❤ ;)

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

Applying the Pythagorean Theorem

$AB^2=AC^2+BC^2$

substitute the given values

$17^2=8^2+BC^2$

solve for BC

$BC^2=17^2-8^2$

$BC^2=225$

$BC=15\ units$

Answer:

Step-by-step explanation:

The rule gives the sequence ...

75, 69, 63, 57, 51, 45, ...

The 5th number in the sequence is 51.

<em>Alternate solution</em>

The equation for the general term of an arithmetic sequence is ...

an = a1 +d(n -1) . . . . . for first term a1 and common difference d

Your sequence has first term 75 and common difference -6, so the equation is ...

an = 75 -6(n -1)

Then for n=5, the term is ...

a5 = 75 -6(5 -4) = 75 -24 = 51

The 5th term is 51.
