Kendra is working on her financial plan and lists all of her income and expenses in the spreadsheet below. What is Kendra’s net cash flow? a. $295 b. $285 c. $275 d. $255
The spreadsheet is missing, so i have attached it.
Answer:
Option A - $295
Step-by-step explanation:
From the spreadsheet, net pay = $2300 and interest earned on savings = $20
Therefore, her total income = $2300 + $20 = $2320
Now,from the spreadsheet, total expenses = 800 + 120 + 90 + 45 + 95 + 80 + 275 + 520 = $2025
Now, net cash flow = Total income - Total expenses
Net cash flow = $2320 - $2025
Net cash flow = $295
Answer:
a. 295

Determine if the following relations represent y as a function of x.
================================================
Explanation:
If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.
Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.
The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.
A function assigns the values. The only function that represents y as a function of x is D.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
For any relation to represent a function in terms of x that represents the value of y, the order of y in the function should be equal to 1, therefore, the power of y should be 1, also, the y variable should be alone(Isolated) on one side of the equal sign.
A.) x = y⁴
It represents x in terms of y, therefore, No.
B.) 6x² + y = 4
It represents constant in terms of x and y, therefore, No.
C.) 6x + y² = -1
It represents constant in terms of x and y, therefore, No.
D.) [tex]y = \sqrt{1-x^2}[/tex]
The given function represents y in terms of x, therefore, it is a function that represents y as a function of x.
E.) -2xy = 1
It represents constant in terms of x and y, therefore, No.
Hence, the only function that represents y as a function of x is D.\

Hopefully it helps!
Please mark brainliest :)
The mid - point between the numbers is 6.545.
We have two decimal numbers → 6.54 and 6.55
We have to determine their mid - point.
You have two numbers - 'x' and 'y'. Find the mid - point between these two numbers.The midpoint (n) between these two numbers will be -
[tex]$n=\frac{x+y}{2}[/tex]
According to the question, we have -
Number 1 → 6.54
Number 2 → 6.55
Assume the mid - point be n. Therefore -
n = [tex]\frac{6.54+6.55}{2}[/tex] = 6.545

How does the area of the scale drawing where 1 centimeter represents 10 miles compare to the area of a the drawing where 1 centimeter represents 30 miles? Area if 1 cm= 10 mi: square miles Area if 1 cm = 30 mi: square miles The area would be times as great.
Answer:
100 square miles900 square miles9 times as greatStep-by-step explanation:
It seems rather obvious that ...
(1 cm)^2 ⇒ (10 mi)^2 = 100 mi^2 . . . on the first drawing
(1 cm)^2 ⇒ (30 mi)^2 = 900 mi^2 . . . on the second drawing
The area on the second drawing is 900/100 = 9 times as great.
_____
These are the areas represented by 1 square cm on the scale drawing. If the drawing is larger, then the represented area is correspondingly larger. The ratio of represented areas is still 9 times for drawings of the same size.

The length of a rectangle is 6 meters more than three times the width. The perimeter of the rectangle is 44 meters. What are the dimensions of the rectangle?
Answer:
width=4
length=18
Step-by-step explanation:
length-6=3width
length=3width+6
also:
perimeter of the rectangle=2(length+width)
44/2=width+length
22=width+length
now put the length we found in the 1st equation, in 22=width+length
=>22=width+3width+6
22-6=4width
width=4
now do the exact same thing with one of these equations:
22=width+length
length=3width+6
I'd do it with the 1st one:
22=4+length
22-4= length
length=18

What is the runner’s average rate of change between the hours: 0.5 and 2? mph 1.5 and 2.5? mph Average Rate of Change
Answer:4mph
5mph
Slower
Step-by-step explanation:
The average rate of change for the runner is 0.667 miles per hour².
How to calculate the average rate of change?To calculate the average rate of change, we follow the following formula:
[tex]a = \frac{v_{2} - v_{1}}{t_{2} - t_{1}}[/tex],
where a is the average rate of change, v₂ is the final speed, v₁ is the initial speed, t₂ is the time for v₂, and t₁ is the time for v₁.
How to solve the given question?In the question, we are asked to find the runner's average rate of change between the hours 0.5 and 2 with speeds of 1.5 mph and 2.5 mph.
So we take, the initial speed v₁ = 1.5 mph, the final speed v₂ = 2.5 mph, the time for v₁, t₁ = 0.5 hours, and the time for v₂, t₂ = 2 hours.
Thus, we can calculate the average rate of change a, using the formula:
[tex]a = \frac{v_{2} - v_{1}}{t_{2} - t_{1}}[/tex],
or, a = (2.5 -1.5)/(2 - 0.5) = 1/1.5 = 0.667 miles per hour².
Therefore, the average rate of change for the runner is 0.667 miles per hour².

Find the slope, x and y intercepts and sketch the graph for the linear equation.
y = 2x + 1
Answer:
In bold below.
Step-by-step explanation:
The slope = coefficient of x = 2.
The y-intercept is when x = 0 and x-intercept is when y = 0.
y = 2(0) + 1 = 1 so the y -intercept is (0, 1).
2x + 1 = 0
x = -0.5 so the x-intercept is (-0.5, 0)

Answer:
Function: [tex]x+y=9[/tex]
Not Function: [tex]x^2+y^2=1[/tex] and [tex]x=y^2[/tex]
Step-by-step explanation:
Given
[tex]x+y=9[/tex]
[tex]x^2+y^2=1[/tex]
[tex]x=y^2[/tex]
Required
Determine if [tex]y[/tex] is a function of [tex]x[/tex]
Solving x+y=9
[tex]x+y=9[/tex]
Make y the subject of formula
[tex]y = 9 - x[/tex]
Hence; y is a function of x
Solving [tex]x^2+y^2=1[/tex]
[tex]x^2+y^2=1[/tex]
Subtract x² from both sides
[tex]y^2=1 - x^2[/tex]
Square root of both sides
[tex]y =\± \sqrt{1 - x^2}[/tex]
This implies that
[tex]y =\sqrt{1 - x^2}[/tex] or [tex]y =-\sqrt{1 - x^2}[/tex]
Because [tex]y[/tex] can be any of those two expressions, it is not a function.
Solving [tex]x=y^2[/tex]
[tex]x=y^2[/tex]
Reorder
[tex]y^2 = x[/tex]
Take square roots
[tex]y = \±\sqrt{x}[/tex]
This implies that
[tex]y = \sqrt{x}[/tex] or [tex]y = -\sqrt{x}[/tex]
Because [tex]y[/tex] can be any of those two expressions, it is not a function.

To shop a package, a company charges a one-time fee plus a fee based on the weight of the package. The table below shows the total shipping costs for four packages of different weights.
Answer:
C = $5 + $1.5(w)
Step-by-step explanation:
Given the following information :
Total shipping cost :
One time fee + fee based on package weight
Given the table :
Weight in pounds - - - - Total shipping cost($)
___4__________________11
___8__________________17
___12_________________23
___16_________________29
We can deduce from the table
For a package that weighs (w) 4 pounds
Total shipping cost = $11
Let one time fee = f
Fee based on weight = r
f + 4(r) = 11 - - - - - (1)
For a package that weighs (w) 8 pounds
Total shipping cost = $17
One time fee = f
Fee based on weight = r
f + 8r = 17 - - - - - (2)
From (1)
f = 11 - 4r - - - (3)
Substitute f = 11 - 4r in (2)
11 - 4r + 8r = 17
-4r + 8r = 17 - 11
4r = 6
r = 6/4
r = 1.5
Put r = 1.5 in (3)
f = 11 - 4(1.5)
f = 11 - 6
f = 5
Hence one time fee = $5
Charge based on weight = $1.5
Hence, Total shipping cost 'C' for a package weighing 'w' will be :
C = $5 + $1.5(w)
Dimensional analysis. How many years of your life will you be sleep if you live 3.95 x 10^7 minutes and average 8 hours sleep/night.
Answer:
The total years of sleep = 25.05 years
Step-by-step explanation:
Given total time in minutes = 3.95 x 10^7
Now convert the total time in hours = (3.95 x 10^7) / 60 = 658333.333 hours
Now covert the total hours into the day. Since a day has 24 hours so divide the total hours by 24 = 658333.333 / 24 = 27430.5555 days.
A person sleeps 8 hours a day, so total hours of sleep = 8 × a number of days.
A person sleeps 8 hours a day, so total hours of sleep = 8 × 27430.5555 days.
Thus, total sleeping hours = 219444.444
Now convert it into a number of years.
Convert total hours into the day and then years.
Number of days = 219444.444 / 24 = 9143.5185 days.
Now covert the total days in to years = 9143.5185 / 365 = 25.05 years
