Use Infinite differences to write the linear function that represents the given data set.
The linear equation on the table is the one in option D.
y = 25*x + 45
How to write the linear function?
A general linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know two points on the line, (x₁, y₁) and (x₂, y₂), the slope can be written as:
a = (y₂ - y₁)/(x₂ - x₁)
Using the first two points, (0, 45) and (1, 70) we can get the slope:
a = (70 - 45)/(1 - 0) = 25
And because of the point (0, 45) we know that the y-intercept is b = 45, then the linear equation is:
y = 25*x + 45
So the correct option is D.

Find the percent the first number is of the second.
(1.) 1.5 and 7.5,
(2.) 5ft 37.5ft
To find the percent that 1.5 is of 7.5, we need to divide 1.5 by 7.5 and multiply the result by 100% to convert it to a percentage:
1.5 / 7.5 = 0.2
0.2 * 100% = 20%
Therefore, 1.5 is 20% of 7.5.
To find the percent that 5ft is of 37.5ft, we need to divide 5 by 37.5 and multiply the result by 100% to convert it to a percentage:
5ft / 37.5ft = 0.1333
0.1333 * 100% = 13.33%
Therefore, 5ft is 13.33% of 37.5ft.

Firstly, the area of a shape is the surface or flat space that the shape covers whereas the perimeter of a shape represents the distance around its boundary. Secondly, the area is measured in square units, whereas the perimeter is measured in linear units.
given that the perimeter of a rectangle is 80 inch
we know that
perimeter = 2 ( L +B)
putting the values we get
80 = 2 ( 12 + B)
40= 12+B
B= 28

you are making a cake and have already put in all of the ingredients except the eggs. you go to the refrigerator and find that there are no eggs, which results in the condition known as
The condition known as "eggless baking" is a common problem when baking cakes and other desserts.
It can be caused by not having eggs in the refrigerator or by forgetting to add them to the recipe. Without eggs, the cake batter lacks structure and will not hold together when baked. Without the proteins from the eggs, the cake will be denser and less moist.
Additionally, the cake may not rise as much as desired and the texture may be crumbly or gummy. To solve this problem, you can try substituting other ingredients such as mashed bananas, applesauce, or yogurt. However, it is best to add eggs if possible to ensure the best results.

find the exact length of the curve. y = 3 + 4x3/2, 0 ≤ x ≤ 1
So the exact length of the curve is given by [tex]L=(1/36)*[\frac{37^{3/2}}{3/2} - 1][/tex]
Given the equation of curve:
[tex]y = 3+ 4x^\frac{3}{2}[/tex]
The length of the curve is given by [tex]L= \int\limits^a_b {\sqrt{1+(y^[/tex]
Where y^ is derivative of y with respect to x
So [tex]y= 4*(3/2) * \sqrt{x}= > 6 \sqrt{x}[/tex]
Given a=1 and b=0
So [tex]L= \int\limits^1_0 {\sqrt{1+(6\sqrt{x})^2 } } \, dx[/tex]
[tex]L= \int\limits^1_0 {\sqrt{1+36x } } \, dx[/tex]
let 1+36x be t
36dx = dt
As the value of x changes after the substitution of the value.
So now the L changes as:
[tex]L= 1/36 \int\limits{\sqrt{t } } \, dt[/tex]
[tex]L=1/36* \left \{ {{t=37} \atop {t=1}} \right. \frac{t^\frac{3}{2} }{\frac{3}{2} }[/tex]

A dance squad needs at least $800 to buy new dance outfits. They have saved $350
already. -They are selling tickets to a dance performance for $10 each. They need to sell
x tickets to have enough money to buy the new dance outfits. Which inequality
represents the situation?
Answer:
x>=45 is the req. inequality
The inequality equation for the number of tickets to be sold is x ≥ 45
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the number of tickets to be sold be x
Let the total amount of money to be saved be = $ 800
The amount of money already saved = $ 350
So , the remaining amount of money = $ 800 - $ 350 = $ 450
The cost of each ticket = $ 10
So , the cost of x tickets = 10x
Now , the number of tickets to be sold to raise $ 450 is given by
10x ≥ 450 be equation (1)
On simplifying the equation , we get
Divide by 10 on both sides of the equation , we get
x ≥ 45
Therefore , the number of tickets to be sold is 45
Hence , the inequality is x ≥ 45

The U.S. Weather Bureau has a station on Mauna Loa in Hawali that has measured carbon dioxide levels since 1959. At that time , there were 312 parts per million of carbon dioxide in the atmosphere. In 2005 , the figure was 389 parts per million. Find the increase in carbon dioxide levels and the percent of increase . Percent increase:96
a) By the subtraction operation, the increase in carbon dioxide levels between 1959 and 2005 is 77 parts.
b) The percentage increase in carbon dioxide levels between 1959 and 2005 is 24.7%.
What is the percentage increase?The percentage increase is found by determining the difference between the original and final values through subtraction operation.
The difference is then divided by the original value, multiplied by 100.
The carbon dioxide levels in 1959 = 312 parts per million
The carbon dioxide levels in 2005 = 389 parts per million
The increase in dioxide levels from 1959 to 2005 = 77 parts per million (389 - 312)

Using 1 balls and bins, n balls are thrown into m bins; m and n are positive numbers. the probability of any given bin containing one ball is n/m n * (1 - (1 - 1/m)^n) / m^2
Given that n is the number of balls and m is the number of bins, the probability of any given bin containing one ball is n/m. Therefore, the variance of x is equal to the variance of a binomial random variable with n trials and probability of success p = n/m.

number being 1, then the two digit number i
After solving the two digit number is 45.
In the given question,
The 2 digit number which become 5 by 6th of itself when it digit are revered.
The difference in the digit of the number being 1, then we have to find the two digit number.
Let the two digit number = 10y+x
When we reversed the number then the number is 10x+y
As given that;
10y+x = 5/6(10x+y)
Multiply by 6 on both side, we get
60y+6x = 50x+5y
Subtract 5y on both side, we get
55y+6x = 50x
Subtract 50x on both side, we get
55y-44x = 0
Divide by 11 on both side, we get
5y-4x = 0
4x-5y = 0......................(1)
It is given that the difference between the number is 1.
x-y = 1..................(2)
Multiply by 4 in equation 2
4x-4y = 4.........................(3)
Now subtract equation 3 and 1, we get
y = 4
Now putting the value of y in equation 2
x-4 = 1
Add 4 on both side, we get
x = 5
Since the number is 10y+x. So
10y+x = 10(4)+5
10y+x = 45

The amount of worth of machine Larry needs to sell to recieve 15,000 dollars is 125, 000 dollars.
How to find the worth of machine he can sell to earn a particular amount?Larry thinks the big money is in rowing machines. If Larry switches jobs,
he will earn a 12% commission on all the machines he sells. For Larry to
receive $15,000 in commissions, the worth of dollars of machines he must
sell can be computed as follows:
Therefore,
let
x = amount he will earn
Hence,
15, 000 = 12% of x
15,000 = 12 / 100 × x
15000 = 12x / 100
cross multiply
1500000 = 12x
divide both sides by 12
x = 1,500,000 / 12
