To evaluate (rs)(4) and (r/s)(3) for the given functions, substitute the value of x into the functions and calculate the product and quotient, respectively.
Explanation:To find (rs)(4), we need to substitute the value of x into the functions r(x) and s(x) and then find their product. r(x) = 2√x, so r(4) = 2√4 = 2√2 = 2(2) = 4. s(x) = √x, so s(4) = √4 = 2. Therefore, (rs)(4) = 4(2) = 8.
To find (r/s)(3), we need to substitute the value of x into the functions r(x) and s(x) and then find their quotient. r(3) = 2√3 and s(3) = √3. Therefore, (r/s)(3) = (2√3) / √3 = 2.

i need to solve this equation: x= r-h/ y
for h and then for r
Answer:
[tex]h=r-xy[/tex]
[tex]r=xy+h[/tex]
Step-by-step explanation:
[tex]x=\frac{r-h}{y}[/tex]
Solve the equation for h
We need to get 'h' alone
[tex]x=\frac{r-h}{y}[/tex]
multiply y on both sides
[tex]xy=r-h[/tex]
Now add h on both sides
[tex]xy+h=r[/tex]
Subtract xy from both sides
[tex]h=r-xy[/tex]
Now solve the equation for 'r'
[tex]x=\frac{r-h}{y}[/tex]
multiply y on both sides
[tex]xy=r-h[/tex]
Now add h on both sides
[tex]xy+h=r[/tex]
[tex]r=xy+h[/tex]
What is the quadrant/axis for (7,-12
Answer:
[tex]\boxed{Quadrant4}[/tex]
The answer should be found in quadrant four it is.
Step-by-step explanation:
x-axis- is a horizontal axis.
y-axis- is a vertical axis.
x-coordinate- is a horizontal position.
y-coordinate- is a vertical position.
quadrant- is a quarter of the coordinate plane.
origin- is a point of intersection of the two axes.
First you had to find quadrant of (7,-12).
Go to the right at it said seven and then go down to the negative twelve and its should be found in quadrant four.
(7,-12) it should be found in quadrant four.
(-7,-12) it should be found in quadrant three.
(-7, 12) it should be found in quadrant two.
(7, 12) it should be found in quadrant one.
Hope this helps!

--- Strep throat is caused by Streptococcus bacteria. The amount of bacteria multiplies at a rate of 10^13 per 10^2 hrs. What is the average growth of bacteria per hour?
The average growth of the bacteria per hour is [tex]10^{11}[/tex].
To find the average growth of bacteria per hour, we need to determine the rate at which the bacteria multiply per hour.
Given:
The amount of bacteria multiplies at a rate of [tex]\(10^{13}\)[/tex] per [tex]\(10^2\)[/tex] hour.
We want to find the growth rate per hour.
First, let's find out how much the bacteria multiplies per hour:
If the bacteria multiply by [tex]\(10^{13}\)[/tex] in [tex]\(10^2\)[/tex] hours, then the average growth per hour can be found by dividing the total growth in [tex]10^{13[/tex] hours by [tex]10^2[/tex].
So, the growth per hour is:
Growth per hour} = [tex]\frac{10^{13}}{10^2}[/tex]
Growth per hour} = [tex]10^{13 - 2}[/tex]
Growth per hour} = [tex]10^{11}[/tex]
Therefore, the average growth of bacteria per hour is [tex]10^{11}[/tex].

A plumber charges $55 for a service call plus $35 per hour. If the plumber's bill was $160, how many hours was he there?
Answer:
Plumber worked for 3 hours.
Step-by-step explanation:
A plumber charges $55 for a service call plus $35 per hour.
Let he works for x hours.
Then for x hours of work charges = $35x
Since plumber charges $55 as a fixed charge so the total charges will be = 55 + 35x
This total amount charged by the plumber equals to $160
and the equation representing this situation will be
55 + 35x = 160
35x = 160 - 55
35x = 105
x = [tex]\frac{105}{35}[/tex]
x = 3 hours
Therefore, he worked for 3 hours.

the product of two consecutive even integers is 48 find the integers
The required integers are -8 and -6, or 6 and 8 whose the product of two consecutive even integers is 48
What are Integers?Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer.
Let the two consecutive even integers be 2n and 2(n+1), where n = any integer.
As per the given condition, The product of the two integers is 48
2n × 2(n+1) = 48
Multiply out, and subtract 48 from both sides
4n2+4n-48=0
Divide both sides by 4
n²+n-12=0
Factor the quadratic
(n+4)(n-3)=0
n= -4 and +3
For n= -4, 2n = -8 and 2(n+1) = -6. (-8)(-6) = 48
For n=3, 2n = 6 and 2(n+1) = 8. (8)(6) = 48
Thus, the required integers are -8 and -6, or 6 and 8.

Find the next three numbers in the pattern: 1, 4, 9, 16, 25, 36, ...
Answer: 49, 64, and 81
Step-by-step explanation: To find the next three terms in this pattern, begin by studying the pattern.
Notice that the difference between 1 and 4 is positive 3, the difference between 4 and 9 is positive 5, the difference between 9 and 16 is positive 7, the difference between 16 and 25 is positive 9, and the difference between 25 and 36 is positive 11.
Since the differences are increasing by 2 each time, we can find the next term in the pattern by adding 36 + 13 to get 49. Next, we will add 49 + 15 to get 64. Then, we will add 64 + 17 to get 81.
Thus, the next three terms in the pattern are 49, 64, and 81.
Deepak is a landscaper who charges $30 for each job he does plus an additional $15 for each hour he works. He only accepts jobs if he will earn at least $90 the job. He writes this inequality to determine x, the number of hours he must work during each job in order to accomplish this.
Answer:
A.) Deepak can only accept jobs that last 4 or more hours.
Step-by-step explanation:
Hope this helps :)
add a thanks...
Deepak must work 4 or fewer hours to earn at least $90 per job.
Explanation:The question is asking about the inequality that Deepak, a landscaper, writes to determine the number of hours he must work during each job in order to earn at least $90 the job. We can break down the equation as follows:
Let x be the number of hours Deepak works.
The equation can be written as: $30 + $15x ≤ $90.
To solve for x, we subtract $30 from both sides: $15x ≤ $60.
Then, we divide both sides by $15: x ≤ 4.
Therefore, Deepak must work 4 or fewer hours to earn at least $90 per job.

Miss Marcus Bulletin Board is 7 ft long and 4 feet High she has 26 ft of board to use Miss Marcus pool supplies 7 time 4 equals 28 to find the exact amount of the board she needs she concludes that she does not have enough border board for the bulletin board do you agree
Final answer:
Yes, I agree that Miss Marcus does have enough board for the bulletin board for the given information
Explanation:
The student is trying to determine if Miss Marcus has enough board to use for her bulletin board. The student calculates the area of the bulletin board as 7 ft x 4 ft = 28 ft². However, the student concludes that Miss Marcus does not have enough board because she only has 26 feet of board to use. This is incorrect, as 26 ft is greater than 28 ft². Therefore, Miss Marcus does have enough board for the bulletin board.

How many 2/3 -cup servings are in four cups of pistachios?
Answer:
4 Of them
Step-by-step explanation:
So an easy way to do this is by adding 2/3 for a while till we hit max. Like this:
2/3+2/3=1 1/3+2/3= 2+2/3=2 2/3+ 2/3= 3 1/3+2/3= 4. so 6 of them
Hope this helps!
Final answer:
To find out how many 2/3-cup servings are in four cups of pistachios, you divide 4 cups by 2/3 cup, which equals 6 servings.
Explanation:
To determine how many 2/3-cup servings are in four cups of pistachios, you would divide the total number of cups by the size of one serving:
Total servings = Total volume \/ Size of one serving = 4 cups / (2/3 cup)
To divide by a fraction, multiply by its reciprocal:
Total servings = 4 / (2/3) = 4 * (3/2) = 4 * 1.5 = 6
So, there are six 2/3-cup servings in four cups of pistachios.
