Expand each logarithm.
log a²
If the expression is log a², then the expansion of this expression looks like 2 log a.
Given that the expression is log a².
We are required to find the expansion of the expression.
The change of base formula gives the way to re-write a logarithm operation as a fraction of logarithms with a new base.
We know that log [tex]a^{b}[/tex]=b log a.
The expression is log a². So,
log a²=2 log a (Power of a will come in front of log)
Hence if the expression is log a², then the expansion of this expression looks like 2 log a.

What single decimal multiplier would you
use to increase by 9% followed by a 6%
decrease?
There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.
What is a multiplier?Simply said, a multiplier is a factor that increases the basic value of another object. For example, a 2x multiplier would double the initial value. On the other hand, a multiplier of 0.5x would actually cut the basic amount in half. In finance and economics, multipliers come in a wide variety.
Say that Number is 100N.
growth of 6%
= (6/100)100N
= 6N
Number following reduction: 100N + 6N = 106N
9% lessening
= (9/100)106N
=954N/100
= 9.54N
Final result after reduction = 106N - 9.54N
=96.46N
=9646N/100
= 9646 * 100N/100 * 100
= 9646 * 100N/10000
= 0.9646 * 100N
There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.

Simplify each number. 1000⁴/₃ / 100³/₂
The result of simplifying each number 1000⁴/₃ / 100³/₂ using the exponent rules is: 10
To solve this exercise we have to resolve algebraic operations following the exponent rules.
(1000⁴/₃) / (100³/₂)
Base: 1000 = 10³
Base: 100 = 10²
As 1000 is the same as 10³ and 100 is the same as 10², we get:
(10³)⁴/₃ / (10²)³/₂
Using the power of a power rule that indicates that: the exponent result will be the multiplication of these exponents, we have:
10³*⁴/₃ / 10²*³/₂
10¹²/₃ / 10⁶/₂
10⁴ / 10³
Using the quotient rule that indicates that: the exponent result will be the subtraction of these exponents, we have:
10⁽⁴⁻³⁾

V = pie r squared h solve for h
The isolated value of h is found to be V/πr²
The three-dimensional solid shape of a cylinder is made up of two parallel bases connected by a curved surface. These bases have the shape of a spherical disc. The axis of the cylinder is a line drawn through the centre or connecting the centres of two circular bases. The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the component.
According to given formulae:
V=πr²h
On dividing both side with πr² we get
⇒V/πr²=πr²h/πr²
(Solving R.H.S)
⇒h=V/πr²

When 4 nightstands are sold the profit is $1800 since the number of nightstands sold is directly proportional to the profit.
The profit is defined as difference between the cost price and sell price for a product.
A directly proportional relationship means that if two variables x and y are proportional to one another then there exist a constant k such that x = y × k .
The graph of a directly proportional equations is a straight line passing through the origin.
Given that the profit is $900 for 2 sold nightstands, $3600 for 8 night stands and $4500 for 10 sold nightstands.
Now this relationship is directly proportional.
So the constant is given by k=900/2=4500/10=3600/8=450
Hence the profit for selling 4 night stands is 450 × 4 =$1800

A solution consisting of 70 mg of dopamine in 70 mL of solution is administered at a rate of 15 mL/hr. Complete parts (a) and (b)
below.
Answer:
The flow rate of dopamine per hour is 15 mg and the duration is 9.3 hours.
Step-by-step explanation:
It is given that A solution consisting of 70 mg of dopamine in 70 mL of solution is administered at a rate of 15 mL/hr.
A solution consisting of 182 mg of dopamine in 26 mL of solution is administered at a rate of 10 mL/hr.
Now, Let's calculate the flow rate of dopamine per hour;
=> Flow rate of dopamine per hour = (70 × 15)/70
=> Flow rate of dopamine per hour = 1050/70
=> Flow rate of dopamine per hour = 15 mg
Further, let's calculate how much the solution should last for a patient that is prescribed to receive 140 mg of dopamine;
=> Prescription = 140 mg
=> Flow rate of dopamine per hour = 15 mg
=> Duration = Prescription/Flow rate of dopamine per hour
=> Duration = 140/15
=> Duration = 9.3 hours
Therefore, the flow rate of dopamine per hour is 15 mg and the duration is 9.3 hours.

Segment ol is a median to the segment cd. cl is =3x-6. ld is =7x-22. find the length of segment cd hi
Length of segment 'cd' = 12 units
Given:-
'ol' is the mid-point of line segment 'cd'
'cl' = 13x + 8
'ld' = 23x - 4
We have to find the length of segment 'cd'.
Since the point 'ol' is the median to the segment cd then two expressions given 'cl' and 'ld' must add up to 'cd'.
'cd' = 'cl' + 'ld'
'cd' = (3x - 6) + (7x - 22)
'cd' = 10x - 28
- To determine the value of x we can also say that 'cl' and 'ld' must be equal because 'ol' is the common mid-point on the line segment 'cd'. So we can write:
'cl' = 'ld'
3x - 6 = 7x - 22
22 - 6 = 7x - 3x
16 = 4x
x = 4 units
- Now substitute the value of x in the expression developed for 'cd' as follows:
'cd' = 10x - 28
'cd' = 10 × 4 - 28
cd = 40 -28
'cd' = 12 units.
Therefore, the length of segment 'cd' is 12 units.

A garden is in the shape of a square with a perimeter of 60 feet. The garden is surrounded by two fences. One fence is around the perimeter of the garden, whereas the second fence is
2 feet from the first fence on the outside. If the material used to build the two fences is $1.21 per foot, what was the total cost of the fences?
The total length between the two fences is 136 ft, and the total cost is 164.56 dollars.
What was the total cost of the fences?We have a square garden with a perimeter of 60ft. Then if the sidelength of the square is S, we have that:
60ft = 4*S
S = 60ft/4 = 15ft
We know that the first fence is around the perimeter of the garden, so the length of the first fence is exactly 60ft.
Now, the other fence is 2ft away from the first fence, so it forms a square of sidelength of:
15ft + 2*2ft = 19ft
Then the perimeter of this square is:
P = 4*19ft = 76ft
This means that the length of the second fence is 76 ft.
So the total length of fence is 76ft + 60ft = 136ft
And the cost is $1.21 per ft, then the total cost for the fence is:
C = 136*$1.21 = $164.56
