(8z^8/4z^4)^-4 please help me to solve this

Anni [7]

8 / 4 = 2 ;
z^8 / z^4 = z^4 ;
then, 8z^4 / 4z^4 = 2z^4 ;
finally, ( 8z^4 / 4z^4 )^ -4 = ( 2z^4 )^ - 4 = 1 / ( 2z^4 )^4 = 1 / [ 2^4 * ( z^4 )^ 4 ] = 1 / ( 16 * z^16 )

A water wheel has a radius of 18 feet. the wheel is rotating at 5 revolutions per minute. find the linear speed, in feet per min

makkiz [27]

Answer:

The linear speed is

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

we have

substitute

step 2

Find the linear speed in feet per minute

we know that

The wheel is rotating at 10 revolutions per minute

Convert revolutions to feet

Remember that

One revolution is equal to the circumference of the circle

so

10 revolutions is equal to

therefore

The linear speed is

The recommended single dose for a particular drug is 100 mg. How many doses can be obtained from 20 grams of the drug?

Lisa [10]

Answer:

B. 200 doses

Step-by-step explanation:

Given,

1 dose is required for 100 mg,

Since, 1 mg = 0.001 g,

⇒ 100 mg = 0.1 g

⇒ 1 dost is required for 0.1 g,

Thus, the ratio of doses and quantity ( in gram ) is $\frac{1}{0.1}=10$

Let x be the doses required for 20 grams,

So, the ratio of doses and quantity is $\frac{x}{20}$

$\implies \frac{x}{20}=10$

$\implies x=200$

Hence, 200 doses can be obtained from 20 grams of the drug.

Option 'B' is correct.

What is the slope of a line perpendicular to the line whose equation is 6x+4y=-56

alex41 [277]

Answer:

First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.Step-by-step explanation:
