Their slopes would be the same but their positions or points ( if the lines were on a graph) would be different.

Option D:

$\frac{25 a^{9} b^{10} }{6 }$ is equivalent to the given expression.

Solution:

Given expression:

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}$

To find which expression is equivalent to the given expression.

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}$

Using exponent rule: $(ab)^m=a^mb^m$

$$=\frac{5^3 a^3 b^{3}}{30 a^{-6} b^{-7}}$

Using exponent rule: $\frac{1}{a^{m}}=a^{-m}, \quad \frac{1}{a^{-m}}=a^{m}$

$$=\frac{125 a^3 b^{3}a^{6} b^{7}}{30 }$

$$=\frac{125 a^3 a^{6} b^{3} b^{7}}{30 }$

Using exponent rule: $a^{m} \cdot a^{n}=a^{m+n}$

$$=\frac{125 a^{3+6} b^{3+7} }{30 }$

$$=\frac{125 a^{9} b^{10} }{30 }$

Divide both numerator and denominator by the common factor 5.

$$=\frac{25 a^{9} b^{10} }{6 }$

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}=\frac{25 a^{9} b^{10} }{6 }$

Therefore, $\frac{25 a^{9} b^{10} }{6 }$ is equivalent to the given expression.

Hence Option D is the correct answer.

Riley needs 32 pirates for every 2 pirate ships he manages.

aleksandrvk [35]

#1 = 96

#2 = 162

There is 16 pirates per ship since there is 32 pirates in 2 ships. This means that you can multiply 16 by 6 and 16 by 12 to get your answers

Find measure of angle b

bogdanovich [222]

Answer:

22°

Step-by-step explanation:

cos B = (c2 + a2 − b2)/2ca

cos B = ( $10^{2}$ + $6^{2}$ - $5^{2}$ )/ 2(10)(6)

cos B = .925

$cos^{-1}$ B = 22.33
