The table compares the initial amount of fuel Li Jing's car had, and the total distance she traveled using that amount, in several different occasions.
Can the total distance be represented as a function of fuel?
Fuel (liters) 1st # , Distance (kilometers) 2nd #
30 100
35 120
40 140
35 120
45 160
25 90
30 100
20 80
Yes or No and why?
Answer:
answer is yes
Step-by-step explanation:
Yes, the total distance can be represented as a function of fuel. The relationship between the two variables can be represented by a linear function. By calculating the slope and y-intercept of the line, we can determine the equation representing the total distance as a function of fuel. which is y = 4x - 20
Explanation:Yes, the total distance can be represented as a function of fuel. In this case, the fuel can be considered as the independent variable and the total distance as the dependent variable. By analyzing the table, we can observe that as the amount of fuel increases, the total distance also increases. This relationship can be represented using a linear function, since the data points seem to form a straight line.
A linear function can be written in the form y = mx + b, where y represents the total distance, x represents the amount of fuel, m represents the slope of the line (which indicates how the total distance changes with each unit of fuel), and b represents the y-intercept (which represents the initial distance when there is no fuel).
By calculating the slope of the line using two data points, we can determine the equation of the linear function. For example, using the first and second data points, we can calculate the slope as:
m = (120 - 100) / (35 - 30) = 20 / 5 = 4
With this information, we can write the function representing the total distance as a function of fuel:
y = 4x + b
To determine the value of b (the y-intercept), we can select any data point and substitute the values of x and y into the function. Let's use the first data point:
100 = 4(30) + b
Solving this equation, we find that b = -20.
Therefore, the equation representing the total distance as a function of fuel is:
y = 4x - 20

Evaluate the expression when y=-6.
y² + 7y - 5
When y is equal to -6, the evaluation of the formula [tex]y^2 + 7y - 5[/tex] is -11.
Explanation:In order to assess this mathematical statement when y=-6, we substitute -6 for y in the expression y² + 7y - 5.
In the expression, swap out y for -6. This gives us (-6)² + 7(-6) - 5.Total up each component. 36, 42, and 5 are the results. Addition and subtraction are to be done left to right. 36 - 42 therefore equals -6, and -6 - 5 equals -11.

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Old factory:
f(x) = 223 (1.09)^x
When x = 0,
f(0) = 223(1.09)^0 = 223(1) = 223
In zero weeks, the number of specialties produced is 223.
When x = 1,
f(1) = 223(1.09)^1 = 243.07 = 243
When x = 2,
f(2) = 223(1.09)^2 = 265.32 = 265
When x = 3,
f(3) = 223(1.09)^3 = 290.41 = 290
When x = 4:
f(4) = 223(1.09)^4 = 318.53 = 318
New factory:
(0, 190), (1, 220), (2, 252), (3, 290), (4, 337)
This means,
(0, 190)
In zero weeks, the number of specialties produced is 190.
Thus,
a)
During week 0, the number of specialty items produced at the old factory than at the new factory.
= 223 - 190
= 33
b)
The growth rates in the weekly number of specialty items produced at each factory.
Old factory:
The growth rate from week 0 to week 1 = (243 - 223)/(1 - 0) = 20/1 = 20
The growth rate from week 1 to week 2 = (265 - 243)/(2 - 1) = 22/1 = 22
New factory:
The growth rate from week 0 to week 1 = (220 - 190)/(1 - 0) = 30/1 = 30
The growth rate from week 1 to week 2 = (252 - 220)/(2 - 1) = 32/1 = 32
c)
The weekly number of specialty items produced at the new factory exceeds the weekly number of specialty items produced at the old factory
in week 4.
i.e
f(4) = 223(1.09)^4 = 318.53 = 318
(4, 337)
318 < 337

Answer: if your question is the same as mine, it should be correct!
Step-by-step explanation:
(a) 40 more specialty items, as 230 (initial value at the Old Factory) minus 190 is 40.
(b) y2 – y1/x2 – x1
252-220/2-1
32
(c) The new factory seems to have a faster production rate.
(d) Week 3 is the week when the production is faster at the New Factory.
p(w)=230(1.1)^w
p(w)=230(1.1)^3
p(w)=230(1.33100)
p(w)= 306.13
At week 3 for the Old Factory, it seems that there is less production happening than the 3rd week at the New Factory.

A bank offers a CD that pays a simple interest rate of 6%. How much must you put in this CD now in order to have $11 comma 700 to replace all the windows in your house in 5 years?
Answer:
You should invest US$ 9,000 in the CD to replace all the windows in your house.
Step-by-step explanation:
Let's recall that the simple interest formula is:
A = P * (1 + r * t), where,
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
Replacing with the real value, we have:
11,700 = P * (1 + 0.06 * 5)
11,700 = P * (1.3)
P = 11,700/1.3
P = 9,000
You should invest US$ 9,000 in the CD to replace all the windows in your house in 5 years.
To calculate the initial deposit for a CD with a 6% simple interest rate in order to have $11,700 in 5 years, you can use the simple interest formula. The formula is rearranged to solve for the initial deposit amount: P = I / RT, where 'P' is the initial deposit, 'I' is the desired amount, 'R' is the interest rate, 'T' is the CD term.
Explanation:The subject of the question is about how much initial deposit you must put into a CD with a simple interest rate of 6% in order to have $11,700 in 5 years. You can find this out by using the formula for simple interest, which is I = PRT. 'I' is the interest, 'P' is the principal amount (what you want to find out), 'R' is the rate of interest, and 'T' is the time in years.
Since you want to find out 'P' (the principal amount), you'd rearrange the formula to P = I / RT. Now you substitute 'I' with $11,700, 'R' with 0.06 (6% expressed as a decimal), and 'T' with 5 years. So, P = $11,700 / (0.06 * 5). From this calculation, you'll be able to determine how much money you need to deposit now into your CD to reach your goal.

We are given -12 = -2a +6
so to find the value of a,
move 6 from rhs to lhs by changing its sign
rhs = right hand side
lhs = left hand side
-12 - 6 = - 2a
-18 = -2a
dividing -18 by -2, we get a = 9

Step-by-step explanation:
All you have to do for this equation to put it into slope-intercept form is to minus 17x from both sides giving you 6y = -17x + 17 which is the correct form. Then you can simplify by dividing everything by 6 but I'll let you do that.
Each bag of candy the factory makes contains 120 pieces of chocolate candy. This week, the factory produced 1800 pieces. Solve the equation below for p to find the number of bags of candy the factory produced. 120p = 1800
Answer:
15 bags
Step-by-step explanation:
120p = 1800
p = 1800/120 =180/12 = 15
Final answer:
To find the number of bags of candy produced, divide 1800 by 120 to get p, which results in p = 15, indicating the factory made 15 bags of candy.
Explanation:
The student is asked to solve the equation 120p = 1800 for p to find out the number of bags of candy the factory produced. In order to find p, we need to perform algebraic operations to isolate the variable on one side of the equation. Here's the step-by-step solution:
Therefore, the factory produced 15 bags of candy.
