What is translation on a coordinate plane?Translation on the coordinate plane is sliding a point or figure in any direction without any changes in size or shape.
During translation, the coordinates of the vertices of a figure or point change, and they slide left or right, up, or down without changing size or shape.
Given the question above, we need to find the coordinates of the vertices for the image of the pre image that are translated 4 units right.
So,

Coliform bacteria are randomly distributed in a river at an average concentration of 1 per 20cc of water. What is the variance of the number of Coliform bacteria in a sample of 40cc of water
Answer:
\(Var = 1.9\)
Step-by-step explanation:
Given
\(p = \frac{1}{20}\) i.e. 1 per 20cc of water
\(n = 40\) -- sample size
Required
The variance
This is calculated using:
\(Var = np(1 - p)\)
So, we have:
\(Var = 40 * \frac{1}{20} * (1 - \frac{1}{20})\)
\(Var = 40 * \frac{1}{20} * \frac{19}{20}\)
\(Var = 2 * \frac{19}{20}\)
\(Var = \frac{38}{20}\)
\(Var = 1.9\)

Lacey inherited some money from her grandfather and put it in a bank account that earns 4%
interest compounded monthly. After 2 years, Lacey had $700.00 in the bank account. How
much interest did she earn?
Round your answer to the nearest cent.
The interest eared from the given amount, rate of interest and time period is $426.883.
Given that, amount = $700, rate of interest = 4% and time period = 2 years.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest is \(Amount=Principal(1+\frac{r}{100})^{nt}\)
Let the money deposited be x.
So, \(700=x(1+\frac{4}{100} )^{2\times12}\)
⇒ \(700=x(1+0.04)^{24}\)
⇒ \(700=x(1.04)^{24}\)
⇒ 700 = 2.563x
⇒ x=700/2.563
⇒ x=$273.117
So, interest = 700-273.117
= $426.883
Therefore, the interest eared from the given amount, rate of interest and time period is $426.883.

Its leading coefficient is positive:
The leading coefficient of a polynomial is the coefficient of the term with the highest degree.
From the graph, if the polynomial is going upwards on the right side, it indicates that the leading coefficient is positive.
It has an odd degree: The degree of a polynomial is the highest power of the variable in the polynomial expression.
If the graph has an odd number of "turns" or "bumps," it indicates that the polynomial has an odd degree.
None of the zeroes have even multiplicity:
The multiplicity of a zero refers to the number of times it appears as a factor in the polynomial.
In the given graph, if there are no repeated x-intercepts or no points where the graph touches and stays on the x-axis, it implies that none of the zeroes have even multiplicity.

How to solve an equation?An equation is an expression that can be used to show the relationship between two or more numbers and variables using mathematical operators.
The area of a figure is the amount of space it occupies in its two dimensional state.
The length of an arc with an angle of Ф is given by:
Length of arc = (Ф/360) * (π * diameter)
The diameter is 16 cm and intercepted arc length is 6 cm, hence:
Length of arc = (Ф/360) * (π * diameter)
6 = (Ф/360) * (π * 16)
Ф = 42.97°
Ф = 42.97° * π/180 = 0.75 radian

Given that line CD is a perpendicular bisector of triangle ABC, if side AB has a length of 6 and side AC has a length of 12 what is the length of side CD? Write your answer to the
nearest hundredth ie 179.50.
Using the Pythagorean Theorem, we can determine that the length of CD is 11.62, rounded to the closest hundredth.
How Should One Put the Pythagorean Theorem Into Practice?When the length of the longest side of a right triangle is squared, the result will be equal to the total of the squares of the lengths of the other two sides of the right triangle that are smaller.
Taking into account the following:
Side AB = 6
Side AC = 12
The perpendicular bisector theory states that AD equals half of AB, which equals half of (6), which equals three.
By using the Pythagorean theorem, we get the following:
The length of the CD is equal to (AC2 - AD2)
The length of the CD is equal to 122 minus 32.
The length of the CD equals (144 - 9)
11.62 is the length of the CD.
Consequently, by using the Pythagorean Theorem, we can determine that the length of the CD is 11.62, rounded to the closest hundredth.

A shipping box is 36 inches by 24 inches by 18 inches
how many cubic feet can it hold
Answer:
To find the volume of the shipping box in cubic feet, we need to convert the dimensions from inches to feet and then calculate the volume.
Given:
Length = 36 inches
Width = 24 inches
Height = 18 inches
Converting the dimensions to feet:
Length = 36 inches / 12 inches/foot = 3 feet
Width = 24 inches / 12 inches/foot = 2 feet
Height = 18 inches / 12 inches/foot = 1.5 feet
Now, we can calculate the volume of the box by multiplying the length, width, and height:
Volume = Length * Width * Height
Volume = 3 feet * 2 feet * 1.5 feet
Volume = 9 cubic feet
Therefore, the shipping box can hold 9 cubic feet.
Step-by-step explanation:
First convert the units because it's asking for the cubic feet but they give us the measurements in inches.
To convert inches to feet we divide the number by 12.
36 ÷ 12 = 3
24 ÷ 12 = 2
18 ÷ 12 = 1.5
Now to find the volume, we multiply it all together.
3 × 2 × 1.5 = 9
It can hold 9 cubic feet.

g'(x)=2ax
for inc interval g'(x) should be +ve
x<0 (i.e. x= -ve), then a must be -ve
for dec interval g'(x) should be +ve
x>0 (i.e. x= +ve), then a must be -ve

Bill weighs 120 pounds and is gaining 12 pounds each month. Phil weighs 200 pounds and is losing 4 pounds each month. How many months will it take for Bill to weigh the same as Phil?
Answer:
Step-by-step explanation:
B=120+12m and P=200-4m
120+12m=200-4m add 4m to each side
16m+120=200, subtract 120 from each side
16m=80, divide each side by 16
m=5
So in five months they will weigh the same.

A person invests 4000 dollars in a bank. The bank pays 5.75% interest compounded quarterly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 5900 dollars?
Answer:
t = 6.8 years
Step-by-step explanation:
The formula for compound interest is
\(A(t)=P(1+r/n)^n^t\), where P is the principal/amount invested, r is the interest rate, n is the number of compound periods per year (4 for quarterly), and t in the time in years.
We know that A = $5900, P = $4000, and r = 0.0575 (we must convert the percentage to a decimal). We must solve for t and round to the nearest tenth:
\(5900=4000(1+0.0575/4)^(^4^t^)\\\\59/40=(1623/1600)^4^t\\\\log(59/40)=log(1623/1600^4^t)\\\\log(59/40)=4t*log(1623/1600)\\\\log(59/40)/log(1623/1600)=4t\\\\1/4(log(59/40)/log(1623/1600))=t\\\\6.80773607=t\\\\6.8=t\)

Which of the following represents the LCM of 98 ab^ 3 and 231 a^ 3 ?
The Least Common Multiple (LCM) for 98 and 231, notation LCM (98, 231), is 3234.
Solution by using the division method:
This method consists of grouping by separating the numbers that will be decomposed on the right side by commas while on the left side we put the prime numbers that divide any of the numbers on the right side. We starting with the lowest prime numbers, divide all the row of numbers by a prime number that is evenly divisible into 'at least one' of the numbers. We stop when it is no longer possible to divide (the the last row of results is all 1's). See below how it works step-by-step.
2 | 98, 231
3 | 49, 231
7 | 49, 77
7 | 7, 11
11 | 1, 11
1 | 1, 1
The LCM is the product of the prime numbers in the first column, so:
LCM = 2 . 3 . 7 . 7 . 11 = 3234
Solution by listing multiples:
This method consists of listing the multiples of all the numbers that we want to find the LCM. Multiples of a number are calculated by multiplying that number by the natural numbers 2, 3, 4, ..., etc. See below:
* The multiples of 98 are 98, 196, 294, 392, 490, 588, ..., 3234
* The multiples of 231 are 231, 462, 693, 924, 1155, ..., 3234
Because 3234 is the first number to appear on both lists of multiples, 3234 is the LCM of 98 and 231.
Hence the answer is The Least Common Multiple (LCM) for 98 and 231, notation LCM (98, 231), is 3234.
