Which situation could this graph represent?
A Running up a hill, then walking up the hill
B Driving a car at the same constant speed.
C Walking down a hill, then running down the hill.
D Driving a car at a fast constant speed, then driving at a slower constant speed.
Answer:
Walking down a hill, then running down the hill.
Step-by-step explanation:
i did it on ttm
The situation the graph represents is walking down a hill, then running down the hill.
Option C is the correct answer.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
The graph represents the speed.
The x-axis is time.
The y-axis is distance.
Now,
The first part of the line indicates a constant speed.
The second part of the line indicates an increase in speed.
Now,
Walking down a hill is a constant speed.
Running down the hill is an increase in speed.
Thus,
Walking down a hill, then running down the hill is represented by the graph.

Hi! I need help with my hw! Repost since people could not see it.
As you can see from the rate of change, 1=16 and 0=0. You can tell by subtracting 48-32 and that'll give you the rate of change which is equivalent go 16. After 6 days, you'll get 96 dollars. I figured that out by adding the rate of change to 80 and that gave me the answer of 96.
how do you graph y= 3x-2
Answer:
Plug in x values into the equation. Start by making a table with x on one side and y on the other. Then, plug in an x value into the equation. We'll start by plugging in 0. This would give us y=3(0)-2, which simplifies to y=-2. Now we know that when x=0, y=-2, so write these two values in your table. Next, we can do this with more points. Let's plug in 1 for x. This gives us y=3(1)-2, which simplifies to y=1 when x=1. Again, we'll write this in our table. After we have a few pairs of x and y values, then we'll draw these points on the graph.
Step-by-step explanation:
The graph of the given linear equation, y = 3x - 2, can be drawn as shown in the coordinate plane attached below.
How to Graph a Linear Equation?To graph y = 3x - 2, choose x-values, calculate the corresponding y-values by substituting them into the equation, plot the points on a coordinate plane, and draw a straight line.
The slope (3) and y-intercept (-2) can be identified from the equation in slope-intercept form (y = mx + b).
Thus, the graph of the linear equation, y = 3x - 2, is shown below.

Complete question :
A chemist is raising the temperature of a liquid. The temperature is now --8.4 degrees Celsius and is increasing by 1.6 degrees Celsius per minute. How many minutes will it take it for it to take to get to 0 degrees Celsius
Answer:
5.25 minutes
Step-by-step explanation:
Given that :
Current temperature = - 8.4°C
Rate of change = 1.6°C per minute
For the temperature to be 0°C ; it will take
(Final temperature - current temperature) rate of change
(0°C - (-8.4°C)) / 1.6°C
(0°C + 8.4°C) / 1.6°C
8.4°C / 1.6°C
= 5.25 minutes

What is the Value of X?
(3x+1) ^1/3=4. Pls show me the steps to do it.
Answer:
x = 21
Step-by-step explanation:
(3x+1) ^1/3=4 means that the 1/3 is an exponent that can be rewritten as a cube root.
You can bring the cube root to the other side of the equation.
1. I chose to bring it to the other side of the equation, making it a cube.
(3x+1) ^1/3 = 4
(3x+1) = 4^3
(3x+1) = 4 * 4 * 4
(3x+1) - 1 = 64 - 1
3x/3 = 63/3

f f(x) = 10-2x and g(x) = 6x - 5, then (f+g) (x) = ?
Answer:
(f+g)(x)=4x+5
Step-by-step explanation:
Just add the two functions together:
(f+g)(x)=f(x)+g(x)=(10-2x)+(6x-5)=-2x+6x+10-5=4x+5
So (f+g)(x)=4x+5

Denise is conducting a physics experiment to measure the acceleration of a falling object when it slows down and comes to a stop. She drops a wooden block with a mass of 0.5 kilograms on a sensor on the floor. The sensor measures the force of the impact as 4.9 newtons. What’s the acceleration of the wooden block when it hits the sensor? Use F = ma.
Answer:
9.8m/s2
Step-by-step explanation:
the mass is 0.5kg
the force is 4.9N
you need to find the acceleration
To find the acceleration, divide the force and mass
4.9N/0.5Kg
the answer is 9.8m/s2
To check, multiply the acceleration to the mass
9.8m/s2*0.5Kg=4.9N
Are the triangles congruent? If so, which of the 5 ways to prove triangles congruent could you use?
We can prove that these triangles are congruent by using SAS congruency rule.
SAS which means Side Angle Side.
In these triangles, we see that two sides are equal in length and one angle is equal.
So, SAS congruency rule is the answer.
Evan and Carter are making chocolate milk which mixes milk with chocolate syrup. Evan's recipe calls for 5 cups of milk for every 4 teaspoons of chocolate syrup. Carter's recipe needs 3 cups of milk for every 2 teaspoons of chocolate syrup. Whose recipe has the stronger tasting chocolate milk?
Answer:
Evan's recipe
Step-by-step explanation:
Given that:
Evan's recipe :
5 cups of milk for every 4 teaspoons of chocolate syrup
Carter's recipe:
3 cups of milk for every 2 teaspoons of chocolate syrup.
Recipe with the stronger tasting chocolate milk:
Take the ratio of cups of milk to teaspoons of chocolate syrup:
Evan's :
5 / 4 = 1.25
Carter's :
3 /2 = 1.5
Evan's recipe has the stronger tasting chocolate milk recipe :
5 milk cup = 4 chocolate spoons
Number of chocolate milks for 3 milk cups = x in Evan's recipe
5 = 4
3 = x
5x = 12
x = 12/5
x = 2.4 teaspoons
This is 2.4 spoons compared Carter's recipe which uses 2 spoons for every 3 milk cups

The distance of the car from the stop sign, d , in feet, at time t , in seconds, can be found using the equation
The average rate of change of a function f(x) on [a,b] is
We need to find the average speed of the car, in feet per second, between t=2 and t=5.
At t=2,
At t=5,
The average speed of the car, in feet per second, between t=2 and t=5 is
The average speed of the car, in feet per second, between t=2 and t=5 is 7.7 feet per second.
Scarlett stopped at a campground along the Appalachian trail. The campground had a 1 2 acre area for tents, which was divided into 6 equal campsites. Scarlett picked one of the sections to pitch her tent. What is the size of Scarlett's campsite?
Answer:
1/12 acres
Step-by-step explanation:
Total area of the campground = 1/2 acres
which was divided into 6 equal campsites
Campsites = 6
Scarlett picked one of the sections to pitch her tent. What is the size of Scarlett's campsite?
Since, the the campground is divided into 6 Equal campsites,
Size of Scarlett's campsite = Total area of the campground / number of campsites
= 1/2 ÷ 6
= 1/2 × 1/6
= 1/12
Size of Scarlett's campsite = 1/12 acres
Each of the 6 campsites = 1/12 acres
Answer:
1/2 divided by 6
6/12 divided by 6

The cafeteria at Local Middle School offers a choice of either a sandwich or soup every Thursday. Of all students who purchased lunch this Thursday, 30 chose a sandwich. If the ratio of students who chose a sandwich to all of those who chose soup was 6:5, how many of the students had soup for lunch?
Answer:
25 students had soup for lunch
Step-by-step explanation:
Sandwich : soup
Of all students who purchased lunch this Thursday, 30 chose a sandwich
Let x = number of students who choose soup
Sandwich : soup = 30 : x
If the ratio of students who chose a sandwich to all of those who chose soup was 6:5
Sandwich : soup = 6 : 5
how many of the students had soup for lunch?
Equate both ratios
Sandwich : soup
30 : x = 6 : 5
30 / x = 6 / 5
Cross product
30 * 5 = x * 6
150 = 6x
Divide both sides by 6
x = 150 / 6
= 25
x = number of students who choose soup = 25 students
Answer:
25
