Expand each logarithm.
log₅ 25/x
If the expression is log₅ 25/x. then the expansion of this looks like
(log 25-log x)/ log 5.
Given that the expression is log₅ 25/x.
We are told to find the expanded value of the expression.
The change of base formula is used in writing a logarithm operation as a fraction of logarithms with a new base.
The expression is log₅ 25/x.
log₅ 25/x=log (25/x)/log 5
(We know that [tex]log_{a} b[/tex]=log b/ log a)
=(log 25-log x)/ log 5 (We know that log (u/v)=log u-log v)
Hence if the expression is log₅ 25/x. then the expansion of this looks like (log 25-log x)/ log 5.

If the learning curve rate is 85%, how long will it take the painter to paint all 20 rooms in stately wayne manor?.
It will take the painter more than 40 hours to paint all 20 rooms in stately wayne manor .
Time taken for the first 3 rooms =9hrs
Learning curve rate = 85%
Time taken for the next 20 rooms =?
Time taken for 1 room = 9hrs / 3 rooms = 3 hrs
If it takes 3 hrs to paint 1 room
Therefore, it will take x hrs to paint 20 rooms would take;
Hence, 20 rooms multiplied 3 hrs = 60 hours
It may take 60 hours to complete painting the 20 rooms.
At a learning curve rate of 85%, 15% will be the progress rate
Therefore, it will take additional 15% of 60 hours to paint the 20 room.

Assume you have applied for two jobs a and b. The probability that you get an offer for job a is 0. 25. The probability of being offered job b is 0. 20. The probability of getting at least one of the jobs is 0. 40. What is the probability that you will be offered both jobs? enter your answer as a decimal rounded to two places.
If you have applied for two jobs a and b and the probability that you get an offer for the job a is 0.25 and the probability of being offered job b is 0.20, then the probability that you will be offered both jobs is 0.05.
Probability is that branch of mathematics that deals with the numerical description of the possibility of an event to occur. The probability of any event is a number between 0 and 1 where 0 represents the impossibility of the event to occur while 1 represents certainty of that event to occur.
As the probability of the job a and job b are independent of each other, the probability that both jobs will be offered can be determined by using the formula;
P(A∩B) = P(A) × P(B)
Here, P(A∩B) represents the probability of both the events happening together
As P(A) = 0.25
P(B) = 0.20
P(A∩B) = 0.25 × 0.20
P(A∩B) = 0.05
Hence, the probability that both jobs will be offered is calculated to be 0.05.

Make n the subject of this formula:
W= an + Z
Answer:
n = (W - Z)/a
Step-by-step explanation:
W = an + Z
Rearrange the equation so that the subject is alone, in the format Ax = B
W = an + Z
W - Z = an + Z - Z
W - Z = an
Isolate the subject by dividing or multiple so that the equation is in the format x = C
W - Z = an
(W - Z)/a = an/a
(W - Z)/a = n

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,

1. To evaluate f(-2)
We have f(x) = x³ - 2x
Substitute -2 for x
==> (-2)³ - (2 x-2)
-2³ = -8
2 x -2 = -4
==> f(-2) = -8 - (-4)
==> f(-2) = -8 + 4 (two negatives make a positive
==> f(-2) = -4 Letter C
2. Evaluate g(-10)
[tex]g(x) = \dfrac{3x}{2}[/tex]

b. The slope of median of triangle passing through point R is 1/4.
c. The slope of the altitude of the triangle that passes through point R doesn't exists.
What is slope of a line segment ?
Slope is the ratio of the difference in y-coordinates over the equivalent x-coordinates between two different locations on a line.
It is given that the vertices of a triangle are P(-6,1), Q(-2,-5) and R(8,1).
a.
The midpoint (M) of QR will be equal to
( [tex]\frac{-2 + 8}{2} , \frac{-5 + 1}{2}[/tex] )
or
M = (-3 , 2)
Now , slope of line QR will be ;
[tex]m_{QR}[/tex] = [tex]\frac{1+5}{8+2}[/tex]
[tex]m_{QR}[/tex] = 6 / 10
We know that :
m × [tex]m_{QR}[/tex] = -1
m = -10 / 6
or
m = -5 / 3
Equation of line will be given as :
y + 2 = [tex]\frac{-5}{3}[/tex] ( x - 3 )
y = [tex]\frac{-5}{3}[/tex] x + 3
b.
The midpoint of PQ will be :
= ([tex]\frac{-6 - 2}{2} , \frac{1 - 5}{2}[/tex])
= ( -4 , -2)
The slope of median of triangle that passes through point R will be ;
m = [tex]\frac{-2 - 1}{-4-8}[/tex]
m = -3 / -12
m = 1/4
or
m = 0.25
c.
Slope of altitude of triangle that passes through point Q will be :
m = [tex]\frac{1 - 1}{-6-8}[/tex]
m = 0 / -14
m = 0
The slope in this case doesn't exist.
Therefore the answers will be :
a. The equation of perpendicular bisector of QR is y = [tex]\frac{-5}{3}[/tex] x + 3.
b. The slope of median of triangle passing through point R is 1/4.
c. The slope of the altitude of the triangle that passes through point R doesn't exists.

The commutative property for addition just means the sum is the same no matter what order you add the terms. This property is also true for multiplication of real numbers.
If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics. Numerous binary operations depend on it as a fundamental property, and numerous mathematical arguments.
A commutative property in mathematics states that if integer positions are switched around or combined while performing addition or multiplication operations, the result will remain the same.
According to the commutative property, the numbers we use can be moved around or swapped around without changing the solution. For addition and multiplication, the property is true, but not for division or subtraction.
