The figure is mad up of two shapes? A semicircle and a rectangle

musickatia [10]

Answer:

Your answer choice is correct.

Step-by-step explanation:

The length of the semicircle is ...

s = π·r = π(4 in)

The three sides of the rectangular section total ...

9 in + 8 in + 9 in = 26 in

The sum of these lengths make up the perimeter of the figure:

P = 4π in + 26 in

P = (4π +26) in

Simplify (2z^5)(12z^3)/4z^4

Sphinxa [80]

Answer:

$6z^{4}$

Step-by-step explanation:

Given in the question an expression,

$\frac{ (2z^5)(12z^3)}{4z^4}$

Step 1

Apply exponential "product rule"

$x^{m}x^{n}=x^{m+n}$

$\frac{ 12(2)z^5)(z^3)}{4z^4}$

$\frac{ (24)z^5)(z^3)}{4z^4}$

$\frac{ 24(z^{(5+3)})}{4z^4}$

$\frac{ 24(z^{8})}{4z^4}$

Step 2

Apply exponential " divide rule"

$\frac{x^{m}}{x^{n}}=x^{m-n}$

$\frac{24/4(z^{8})}{z^4}$

$\frac{6(z^{8})}{z^4}$

$\frac{6(z^{8-4})}{1}$

$6z^{4}$
