Answer: The product is 5^-4 or 0.0016 (decimal)

Step-by-step explanation:

Hi, to solve this we have to apply the product rule, that says that if we multiply two powers that have the same base, the exponents can be added.

So, mathematically speaking:

(5^-1 )(5 ^-3) = 5 ^-4

Or, the decimal expression by solving:

5^-4= 0.0016

Javier used the equivalent ratios to find the number of millimeters in 8 inches. StartFraction 8 inches Over question mark milli

joja [24]

Answer:

203.20 millimeters

Step-by-step explanation:

StartFraction 8 inches Over question mark millimeters EndFraction = StartFraction 40 inches Over 1,016 millimeters

8 inches / ? Millimeters = 40 inches / 1,016 millimeters

8 × 1,016 = ? × 40

8,128 = 40?

Divide both sides by 40

? = 8,128 / 40

= 203.20

? = 203.20 millimeters

There are 203.20 millimeters in 8 inches

I am really confused about this question for math.. any help would be really appreciated:

Elina [12.6K]

$y= (\frac 1 4 )^x$

A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so

$y'= -y = - (\frac 1 4)^{x'}$

A dilation of 2 is the mapping (x'',y'')=(2x', 2y')

$x'=x''/2, y'=y''/2$

$y''/2= - (\frac 1 4)^{x''/2}$

$y'' = - 2((\frac 1 4)^{1/2})^{x''}$

$y''= - 2(\frac 1 2)^{x''}$

We can rewrite that without the primes and combine the powers of 2.

$y = - 2^{1-x}$

Let's graph these and see if we're close,

Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}
