The distance traveled by car in 8 seconds is 96 meters if the distance-time relationship is 12s+3s²
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
A car can travel a distance of (12s+3s²) meters over some number of seconds s.
The above expression is representing an equation for the distance at the given time or seconds s.
Let's suppose:
f(s) = (12s+3s²)
Let's assume the total distance traveled by car in 8 seconds is x meters.
Then at s = 8 seconds f(8) = x put these values in the above function, we get:
f(8) = 12×8 - 3×8²
x = 96 - 192
x = -96
The distance cannot be a negative quantity, so taking the absolute value of x
|x| = 96 meters
Thus, the distance traveled by car in 8 seconds is 96 meters if the distance-time relationship is 12s+3s²

-4(2+8)=(-4xN)= Show your answers
Answer:
n=10
Step-by-step explanation:
[tex] - 4(2 + 8) = ( - 4 \times n) \\ \frac{ - 4(10)}{ - 4} = \frac{ - 4n}{ - 4} \\ 10 = n[/tex]
Answer:
−4(2+8)=−4n
Step 1: Simplify both sides of the equation.
−40=−4n
Step 2: Flip the equation.
−4n=−40
Step 3: Divide both sides by -4.
[tex]\frac{-4n}{4} = \frac{-40}{-4}[/tex]

Solve the system of equations below by elimination. Write your answer as an ordered pair. e.g. (2,3)
Answer:
(45,35)
Step-by-step explanation:
1 - Stack the equations on top of each other
3x - 4y = -5
4x + 4y = 40
2 - We can eliminate by subtracting the bottom equation from the top equation
3x - 4y = -5
- 4x - 4y = 40
3 - The y's cancel out, leaving us with...
3x = -5
- 4x = 40
4 - Continue simplifying
-1x = -45
5 - We can switch the -1x with -x to make things simple
-x = -45
6 - Positize (make it positive) the statement
x = 45
7 - Halfway there! Substitute the x value into one of the equations
(3 * 45) - 4y = -5
8 - Solve
135 - 4y = -5
Minus 135 on both sides
-4y = -140
Divide by -4 on both sides
y = 35
9 - Here is your answer!!
x = 45
y = 35
(45,35)

Step-by-step explanation:
a)
48 = d + 23
48 - 23 = d + 23 - 23
25 = d + 0
25 = d
b)
W - 13 = 28
W - 13 + 13 = 28 + 13
W + 0 = 41
W = 41
c)
[tex]9x = 72\\\\\frac{9x}{9} = \frac{72}{9}\\\\x = 8[/tex]
d)

Answer: a) Surface Area : 488 [tex]cm^{2}[/tex]
Volume : 672 [tex]cm^{3}[/tex]
b) Surface Area
c) Volume
Step-by-step explanation:
The object given is a cuboid. A cuboid has 6 sides.
To calculate the surface area and volume, we need the dimensions of the cuboid which are the length(l), breadth(b), and height(h).
According to the image given, l = 14 cm, b = 8 cm, and h = 6 cm.
a) Surface Area:
The formula for the surface area of a cuboid is = 2*((l*b)+(l*h)+(b*h))
Therefore, the surface area = 2*((14*8)+(14*6)+(8*6)) = 488 [tex]cm^{2}[/tex]
The area is always denoted as [tex]cm^{2}[/tex]
Volume:
The formula for volume of a cuboid is = l*b*h
Therefore, the volume = 14*8*6 = 672 [tex]cm^{3}[/tex]
The area is always denoted as [tex]cm^{3}[/tex]
b) Plating is done to usually protect the surface area of an Object. Therefore the answer is Surface Area.
c) If the brick is made of concrete, it means that the whole space occupied by the brick consists of concrete. Therefore volume is the right option.

Jezebel took a train to visit her uncle. The train traveled at a constant speed of 40 miles per hour. Complete the table. Then, write an equation to find the total distance d traveled after t hours.
Answer:
[see below]
Step-by-step explanation:
We can tell that for every hour passed the distance traveled by the train would increase by 40 miles.
We can use the equation d = 40t to determine the values of the table. The 'd' is total distance and 't' is the number of given hours.
Two hours:
d = 40(2)
d = 80
Three Hours:
d = 40(3)
d = 120
Four Hours:
d = 40(4)
d = 160

At the Manchester Ice Cream Parlor, one group of friends ordered 1 small serving of ice cream and 1 large serving of ice cream for $5. Another group of friends ordered 4 small servings of ice cream and 5 large servings of ice cream for $24. How much does the ice cream cost?
The ice cream costs $__ for a small serving and $__ for a large serving.`
Answer:
$24
Step-by-step explanation:
5 large servings = 4 + 4 + 4 + 4 + 4 = $20
4 small servings = 1 + 1 + 1 + 1 = $4
20 + 4 = $24
The ice cream costs $1 for a small serving and $4 for a large serving.
