A person can rent any of the vehicles shown in the table for a minimum of two to three days before it becomes more expensive for a week.
Algebra state that it is the study of the laws and symbols of mathematics as well as the manipulation of these symbols.
The rent of the small car for a week is $250 and for a day is $100. Then,
The maximum number of days that a car could be rented is,
= 250÷100
= 2.5 days
≅ 3 days
Then, for the medium car is,
= 290÷110
= 2.7 days
≅ 3 days
For the luxury car is,
= 325÷120
= 2.7 days
≅ 3 days
For Small van is,
= 350÷150
= 2.3 days
≅ 2 days
For Large van is,
= 390÷170
= 2.2 days
≅ 2 days
We can conclude from the above calculations that a person can rent a car for 2-3 days before it becomes more expensive for a week.
The complete question is -
For any of the vehicles listed in the table, how many days can you rent the vehicle before it would be less expensive to rent for the week?

There are 7 1/2 pounds of potatoes. 1/6 of the potatoes are rotten. What is the weight of good potatoes. Fraction form
Answer:
6 1/4 pounds
Step-by-step explanation:
There are 7 1/2 pounds of potatoes, which is equivalent to 7 1/2 = 7.516=120
120 ounces of potatoes.
If 1/6 of the potatoes are rotten, then 1/6*120 = 20
20 ounces of potatoes are rotten.
Thus, the weight of the good potatoes is 120-20 = 100
100 ounces.
Converting this back to pounds, we get
100/16 = 6 1/4
6 1/4 pounds.
The force,
F
(Newtons), between two objects is inversely proportional to the square of the distance,

The force is 0.045 Newtons when the distance between the objects is 2.4 metres.
Work out
d
(rounded to 2 DP) when
F

Newtons.
The value of d when F = 0.7 Newton's by solving with inverse variation is 0.61 meters to 2 D.P
How to find inverse variation?Let
F = force in Newton'sd = distance in metersF = k/ d²
Where k = constant of proportionality
If F = 0.045 Newtons and d = 2.4 metres
F = k/ d²
0.045 = k / 2.4²
cross product
k = 0.045 × 2.4²
k = 0.2592
Find d when F = 0.7 Newton's
F = k/ d²
0.7 = 0.2592 / d²
cross product
0.7 × d² = 0.2592
0.7d² = 0.2592
divide both sides by 0.7
d² = 0.2592 / 0.7
d² = 0.370285714285714
find the square root of both sides
d = √0.370285714285714
d = 0.6085110634045
d = 0.61 to 2 decimal place.

Opposite numbers:-
Every number has an opposite. In fact, every number has two opposites: the additive inverse and the reciprocal—or multiplicative inverse. Don't be intimidated by these technical-sounding names, though. Finding a number's opposites is actually pretty straightforward.
If a number is added to its additive inverse, the sum of both the numbers becomes zero.
For any given number, the additive inverse is a number or a value which when added to the original number results in zero.
Mathematically: a + (-a) = 0
So here, 'a' and '-a' are the additive inverses of each other.
Therefore, for 4, the additive inverse is 4 = -4

Find the derivative of the function. y = arctan √[(1 − x) /(1 + x)]
y' = ?
The derivative of the function y = [tex]tan^{-1}[/tex] √[(1 - x)/(1 + x)] is given by
y' = -1/[(1 + x)²× √[(1 - x)/(1 + x)]].
To find the derivative, we use the chain rule. The derivative of the outermost function, arctan, is
1/[1 + (√[(1 - x)/(1 + x)])²], and the derivative of the innermost function, the square root, is
-1/2×(1 - x)/[[tex](1+x)^{3/2}[/tex])]. Multiplying these two derivatives together gives us the final result.
1/[1 + (√[(1 - x)/(1 + x)])²]×-1/2×(1 - x)/[[tex](1+x)^{3/2}[/tex])]
=-1/[(1 + x)²× √[(1 - x)/(1 + x)]].
When we take the derivative of a function, we are essentially finding the slope of the tangent line of a function at a given point. This derivative will tell us the rate at which y changes with respect to x. The derivative of the function y = [tex]tan^{-1}[/tex] √[(1 - x)/(1 + x)] is a negative value, which means that as x increases, y decreases. Therefore, this function has a negative slope.

Zachary is a waiter at a restaurant. Each day he works, Zachary will make a guaranteed wage of $40, however the additional amount that Zachary earns from tips depends on the number of tables he waits on that day. From past experience, Zachary noticed that he will get about $7 in tips for each table he waits on. How much would Zachary expect to earn in a day on which he waits on 11 tables? How much would Zachary expect to make in a day when waiting on tt tables?
Zachary expects to make $40 + $7 x tt (number of tables) in a day when waiting on tt tables
If Zachary waits on 11 tables, he can expect to make an additional $7 in tips for each table, for a total of 11 tables * $7/table = $77 in tips.
When added to his guaranteed wage, Zachary can expect to earn $40 (guaranteed wage) + $77 (tips) = $117 for that day.
To calculate how much Zachary would expect to make in a day when waiting on tt tables, we can use the equation:
Earnings = $40 (guaranteed wage) + $7 (tips/table) x tt (number of tables)
So if tt represents the number of tables Zachary waits on, then he can expect to earn:
Earnings = $40 + $7 x tt
For example, if Zachary waits on 15 tables, he can expect to earn $40 + $7 x 15 = $190.
Zachary can use this equation to calculate his expected earnings for any number of tables he waits on in a day.

To figure out the number of cookies they will need, they multiply the number of students by the number of cookies per student, which is 81 students * 2 cookies= 162 cookies.
Since each recipe makes 15 cookies, they need to make 162 cookies / 15 cookies/recipe = 10.8 recipes.

Parallel computing is a sort of computation in which several computations or processes are performed at the same time. Large issues are frequently broken into smaller ones, which may then be tackled concurrently.

Which of these is the absolute value parent function?
A. f(x) = x
OB. f(x) = 2ˣ
OC. f(x) = x²
OD. f(x) = Ixl
Option D) f(x) = |x|, is Correct.
What is parent function?
A parent function is a basic or fundamental function that serves as the starting point for a family or group of related functions. These functions can be obtained by applying a transformation to the parent function, such as shifting, stretching, or reflecting it.
The absolute value parent function is represented by the following function:
D. f(x) = |x|
The absolute value function is defined as |x| = x for x >= 0 and |x| = -x for x < 0. Graph of this function is a V-shape, and it's also known as "the absolute value of x" function. It is a reflection of the linear function f(x) = x across the x-axis and will always have a slope of 1 and a y-intercept of 0.
A. f(x) = x is a linear function, slope is 1 and y-intercept is 0, This is not absolute value function
B. f(x) = 2ˣ is the exponential function, and it is not an absolute value function
C. f(x) = x² is the quadratic function, it's a parabola opening upwards and not an absolute value function
D. f(x) = |x| is the absolute value function, V-shape and it's an example of the absolute value parent function.

The line has a slope 5 / 4 and passes through ( − 3, 4 ). What is the equation of the line ? Select one: a. 4x + 5y + 31 = 0 b. 5x − 4y + 31 = 0 c. 4x − 5y + 31 = 0 d. 5x − 4y − 31 = 0
Answer:
b: 5x-4y+31=0
Step-by-step explanation:
Let's look for an equation of the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
We are given the slope, m, as (5/4), so we can write: y = (5/4)x+b.
To find b, just enter the given point, (-3,4), into the above equation and solve for b:
y=(5/4)x + b
4=(5/4)(-3) + b for (-3,4)
4 = -(15/4)+b
4 + (15/4) = b
4 + (3 3/4) = b
b = 7 3/4
The equation becomes y = (5/4)x + 7 3/4
Also written as: y = (5/4)x + (31/4)
To match this with one of the options, let's multiply by 4 to remove the two fractions:
y = (5/4)x + (31/4)
4y = (5)x + (31)
Rearrange so that the expression is = 0:
4y-5x-31 = 0
Now multiply by -1: -4y+5x+31=0
Rearrange and this will match option b: 5x-4y+31=0
