Answer:

C. $\huge\frac{1}{3x {y}^{2} {z}^{4}}$

Step-by-step explanation:

$(9 {x}^{2} {y}^{4} {z}^{8} )^{ - \frac{1}{2} } \\ \\ = ( {3}^{2} {x}^{2} {y}^{4} {z}^{8} )^{ - \frac{1}{2} } \\ \\ = \frac{1}{( {3}^{2} {x}^{2} {y}^{4} {z}^{8} )^{ \frac{1}{2} }} \\ \\ = \frac{1}{(3x {y}^{2} {z}^{4})^{2 \times \frac{1}{2} } } \\ \\ = \frac{1}{3x {y}^{2} {z}^{4}} \\ \\ \red{ \bold{ \therefore \: (9 {x}^{2} {y}^{4} {z}^{8} )^{ - \frac{1}{2} } = \frac{1}{3x {y}^{2} {z}^{4}} }}\\$

If f(x) = -5, then f(-3)=

vitfil [10]

Answer:

f(-3)= -5

g(4)= 7

Step-by-step explanation:

here f(x)= -5, clearly it's not depending on 'x' ,so it will have same value,for all x

i.e, f(-3) is also -5

and, g(x)=2x-1

to get g(4) put x=4 in 2x-1

i.e, (2×4)-1 =7

An article costing Gh37000 was sold for Gh31450. What is the loss percent

Gennadij [26K]

Answer:

15%

Step-by-step explanation:

The first step is to find the loss

Cost price -selling price

37000-31450

= 5,550

The loss percent can be calculated as follows

= loss/cost price × 100

= 5550/37000 × 100

= 0.15×100

= 15%

Hence the loss percent is 15%
