Write an equation for the graph below which represents a logarithmic function f with base 2 or 3 translated and/or reflected. X=3 (7,1) (5,0) (4,-1)
Answers
Answer:
The answer is "[tex]\log(x-3)- \log(2)[/tex]"
Step-by-step explanation:
The asymptote is that when the group is 0 within. Let's all assume that log base 2 is: Log(ax-b); a position mostly online also they know. Let's use this (5,0) and log(5a-b)=0; they get out of it 5a-b=1; now that the results for a and b must be known. So we can say unless the asymptote is x=3, 3a-b=0; then we have the equations system, and with a and b we can solve
[tex]\to b=5a-1 \\\\ \therefore\\\\\to 3a-(5a-1)=0\\\\\to 3a-5a+1=0\\\\\to -2a+1=0\\\\\to -2a=-1\\\\\to a=\frac{1}{2} \ and\ b= \frac{3}{2}[/tex]
[tex]\to \log(\frac{x}{2}-\frac{3}{2})\\\\\to \log(\frac{(x-3)}{2})\\\\\to \log(x-3)- \log(2)[/tex]
The different kinds of beads that Casey is
using to make purses come in packages of
3 and 9. What is the least number of each
kind of bead that Casey can buy to have an
equal number of each of the different kinds
of beads?
Answers
Answer:
Casey can buy 3 packages with 3 beads and one package with 9 beads to have the same number of beads of each kind.
Step-by-step explanation:
Given that:
The beads come in packages of 3 and 9.
To calculate the least number of beads that Casey can have, we will find the least common multiple of both packages.
Package of three = 3, 6, 9, 12, 15
Package of nine = 9, 18, 27, 36
The least common multiple of 3 and 9 is 9.
Hence,
Casey can buy 3 packages with 3 beads and one package with 9 beads to have the same number of beads of each kind.

The distribution of random variable R has mean 10 and standard deviation 4. The distribution of random variable S

distribution of R-S?
Mean 3 and standard deviation 1
B
Mean 3 and standard deviation 5
Mean 3 and standard deviation 7
mong
D
Mean 17 and standard deviation 1
E
Mean 17 and standard deviation 5
Answers
Answer:
(B) Mean 3 and standard deviation 5
Step-by-step explanation:
Property of mean
The mean of the sum or difference of two random variable R and S is the sum of their means.
μ (R-S) = μ(R) - μ(S)
μ(R-S) = 10 - 7 = 3
Property of standard deviation
The variance of Independent variable R and S is is the sum of their variances. Even when we subtract two random variables, we still add their variances; subtracting two variables increases the overall variability in the outcomes.
σ^2(R-S) = σ^2 (R) + σ^2(S)
= 16 + 9 ( variance = (standard deviation)^2 )
= 25
σ(R-S) = 5
The mean of the distribution of R-S is 3 and the standard deviation of the distribution of R-S is 5 and this can be determined by using the given data.
Given :
The distribution of random variable R has a mean of 10 and a standard deviation of 4. The distribution of random variable S has mean 7 and standard deviation 3.The following steps can be used in order to determine the mean and standard deviation of the distribution of R-S:
Step 1 - The mean can be determined by using the below formula.
[tex]\rm \mu(R-S) = \mu(R)-\mu(S)[/tex]
Step 2 - Substitute the values of [tex]\rm \mu(R)[/tex] and [tex]\rm \mu(S)[/tex] in the above expression.
[tex]\rm \mu(R-S) = 10-7[/tex]
[tex]\rm \mu(R-S) = 3[/tex]
Step 3 - The standard deviation can be determined by using the below formula.
[tex]\rm \sigma^2(R-S) = \sigma^2(R)+\sigma^2(S)[/tex]
Step 4 - Substitute the values of [tex]\rm \sigma(R)[/tex] and [tex]\rm \sigma(S)[/tex] in the above expression.
[tex]\rm \sigma^2(R-S) = 16+9[/tex]
[tex]\rm \sigma(R-S) = 5[/tex]
Therefore, the correct option is B).

5. Rex deposited $900 into an

take for the value of the
account to reach $1,800?
Answers
Answer:
well, there is already $900 so 1800-900=900 now we need 4% of 900 which is $36 900 divided by 36 is 25
it will take 25 years
Step-by-step explanation:
plz mark brainliest i answered first
The number of years that will it take for the value of the account to reach $1,800 should be 25 years.
Calculation of the number of years:Since the deposited amount is $900
The rate of interest is 4%
The future value is $1,800
So here the balance amount should be
= $1,800 - $900
= $900
Now 4% of $900 = 36
So the number of year should be
= [tex]900\div 36[/tex]
= 25 years
hence, The number of years that will it take for the value of the account to reach $1,800 should be 25 years.

Combine your like terms

Like: r + 31 - 31 = 1 - 31
Cancel out: 31 - 31 because that gives you 0
Keep: 1 - 31 because that gives you the value of “r”
1 - 31 = -30
Therefore, your answer is: r = -30 ☑️

Answer:
y(0) = 3
Step-by-step explanation:
This is solved by plugging in each option one by one, and seeing which one results in a positive value for dy/dt.
dy/dt = (4 − 1) (1 − 2²) = -9
dy/dt = (7 − 1) (1 − 1²) = 0
dy/dt = (1 − 1) (1 − 2²) = 0
dy/dt = (-4 − 1) (1 − 0²) = -5
dy/dt = (3 − 1) (1 − 0²) = 2
Only the last option fits.

An urn contains 17 white balls and 18 red balls. A sample of four balls is selected at random from the urn. What is the probability that the sample contains two white balls and two red ones?
a. 0.0286
b. 0.2286
c. 0.3974
d. 0.0944
e. 0.0442
f. None of the above.
Answers
Answer:
c. 0.3974
Step-by-step explanation:
Given;
number of white balls, W = 17
number of red balls, R = 18
Total number of balls, T = 35
The number of ways the event will occur is given by
= P(2 whites) and P(2 reds)
= P(2whites) x P(2 reds)
= 17C2 x 18C2
= 136 x 153
= 20,808
The total number of possible outcome
= 35C4
= 52,360
The probability = 20,808 / 52,360
= 0.3974
The correct option is "C"
Probability that the sample contains two white balls and two red ones is equal to 0.3974.
So, option c. is correct.
Permutations and combinationsProbability is a discipline of mathematics concerned with numerical explanations of the likelihood of an event occurring or the truth of a claim.
Number of white balls [tex]=\boldsymbol{17}[/tex]
Number of red balls [tex]=\boldsymbol{18}[/tex]
Total number of balls [tex]=\boldsymbol{35}[/tex]
Probability that the sample contains two white balls and two red ones
