Step-by-step explanation:
From the table we can make comparison between the distance travelled and the time taken. It can be seen that the time increases as the distance decrease.
If the car travels 700 miles in 0.5seconds and 600miles in 1.5secs, we can calculate the speed of the car using the formula;
v = change in distance/change in time
v = ΔS/Δt
v = 700-600/0.5-1.5
v = 100/-1
v = -100mi/hr
Since Speed = Distance/Time
-100 = 480/Time
Time = 480/-100
Time = -4.8s
Hence it will take the car 4.8seconds to travel 480miles.

what are the intersections between the lines y=x squared and 6x + 3y= 24?
Answer:
The intersection points between the functions are (-4,16) and (2,4)
Step-by-step explanation:
Intersection Between Functions
We are given the functions:
[tex]y=x^2[/tex]
[tex]6x+3y=24[/tex]
To find the intersections between them, we have to solve the system of equations. Let's start by simplifying the second equation by 3:
[tex]2x+y=8[/tex]
Now we substitute [tex]y=x^2[/tex] into this equation:
[tex]2x+x^2=8[/tex]
Solve the quadratic equation by any of the available methods.
Subtract 8:
[tex]2x+x^2-8=0[/tex]
Sort the polynomial:
[tex]x^2+2x-8=0[/tex]
Factor:
[tex](x+4)(x-2)=0[/tex]
Solve:
[tex]x=-4, x=2[/tex]
Now find the y-coordinate of each solution:
[tex]y=x^2=(-4)^2=16[/tex]
The point is (-4,16)
For x=2:
[tex]y=x^2=2^2=4[/tex]
The point is (2,4)
The intersection points between the functions are (-4,16) and (2,4)
0 is a COMPOSITE number.

How do I write this equation? Pls help ASP
This is a question about angles and equations! Let's see how to solve this.
The angle [tex]\angle PQR[/tex] is the sum of the angles [tex]\angle MQR[/tex] and [tex]\angle PQM[/tex]. So, we can do a equation with this information and solve it:
[tex]\angle PQR = \angle MQR + \angle PQM\\\\138x -1 = 115 + 23x -1\\138x - 23x = 115 + 1 - 1\\115x = 115\\x=\frac{115}{115} \\x= 1[/tex]
Therefore, the value of x is 1.
The function f has the property that as x gets closer and closer to 4, the values of f(x) get closer and closer to 7. Which of the following statements must be true?
Answer:
C
Step-by-step explanation:
x going to 4 is given by limx->4 and closer to 7 is given by =7
The correct statement is [tex]\lim_{x \to 4} f(x)[/tex] = 7.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given statement:
x gets closer and closer to 4, the values of f(x) get closer and closer to 7.
So, x gets closer and closer to 4 shows
x-> 4
and, f(x) get closer and closer to 7 shows
f(x)=7
Combining both we can write using the limit function x gets closer and closer to 4 require limit
[tex]\lim_{x \to 4} f(x)[/tex] = 7.

A family is planning a camping trip at a state park. The state park has 9 campgrounds, each with 6 campsites. The family wants to go on a hike, and the park has 4 hiking trails. The children also want to go for a swim at one of the 4 beaches. How many different ways can the family plan a camping trip?
Answer:
62
Step-by-step explanation:
Camping trip different ways = No of campgrounds x campsites each campground
9 x 6 = 54
Hiking trip different ways = 4 (hiking trails)
Swimming different options = 4 (beaches)
Total ways of planning trip = 54 + 4 + 4 = 62
