What are the initial and final potition respectively
The initial position is the starting point, and the final position is the endpoint.
We proceed to explain the initial and final position:
The initial position is the starting point or location of an object before any movement or displacement occurs. It is often denoted as x0 or xi. The final position is the ending point or location of an object after it has undergone movement or displacement. It is often denoted as xf.For example, if an object starts at the 2 meter mark (initial position) and moves 3 meters to the right, its final position would be at the 5 meter mark.

Logan owns a trucking company. For every truck that goes out, Logan must pay the
driver $16 per hour of driving and also has an expense of $1.25 per mile driven for
gas and maintenance. On one particular day, the driver drove an average of 20 miles
per hour and Logan's total expenses for the driver, gas and truck maintenance were
$205. Write a system of equations that could be used to determine the number of
hours the driver worked and the number of miles the truck drove. Define the
variables that you use to write the system.
Answer:
Let's define the variables:
h: the number of hours the driver worked.
d: the number of miles the truck drove.
We know that the driver is paid $16 per hour, so the cost of the driver's labor is:
16h
We also know that the truck incurs an expense of $1.25 per mile driven, so the cost of gas and maintenance is:
1.25d
The total expenses for the driver, gas, and maintenance were $205, so we can set up the following equation:
16h + 1.25d = 205
We also know that the average speed of the truck was 20 miles per hour, so we can set up the following equation:
d = 20h
So the system of equations that could be used to determine the number of hours the driver worked and the number of miles the truck drove is:
16h + 1.25d = 205
d = 20h
These two equations can be solved simultaneously to find the values of h and d that satisfy both equations.
A town is designing a rectangular park that will be 600 feet by 1000 feet. A rectangular area of the park for swing sets will be 25 feet by 100 feet. On a scale drawing of the park the swing set area is 0. 5 inch by 2 inches. What is the dimensions of the park on the scale drawing?
The dimensions of the park on the scale drawing are 2 inches by 0.5 inches
The dimensions of the park on the scale drawing can be determined by using the scale factor between the actual dimensions and the scale drawing dimensions. The scale factor can be found by dividing the actual dimensions by the scale drawing dimensions.
Scale factor for length = Actual length / Scale drawing length = 1000 feet / 2 inches = 500 feet per inch
Scale factor for width = Actual width / Scale drawing width = 600 feet / 0.5 inches = 1200 feet per inch
Now, we can use the scale factor to determine the dimensions of the park on the scale drawing.
Length of park on scale drawing = Actual length / Scale factor for length = 1000 feet / 500 feet per inch = 2 inches
Width of park on scale drawing = Actual width / Scale factor for width = 600 feet / 1200 feet per inch = 0.5 inches
Therefore, on the scale drawing, the park measures 2 inches by 0.5 inches.

Group of answer choices

The number outcomes in the sample space is option (3) 64
In mathematics, combination is a way of selecting a group of objects from a larger set, where the order in which the objects are selected does not matter.
The number of outcomes in the sample space can be calculated by finding the total number of possible combinations of genders for the six children.
For each child, there are two possible genders: male or female. Therefore, the number of possible outcomes for one child is 2.
To find the total number of outcomes for six children, we need to multiply the number of possible outcomes for each child together:
2 × 2 × 2 × 2 × 2 × 2 = 64

An algebra over a field F is a vector space over F equipped with a bilinear operation called multiplication.
Let F be a field and let A be a vector space over F. An algebra over F is a triple (A, ×, 1) where × is a bilinear operation A x A -> A, and 1 is an element of A such that:
a × (b × c) = (a × b) × c for all a,b,c in A (associativity)
There exists an element 1 in A such that a × 1 = a = 1 × a for all a in A (existence of identity)
a × (b + c) = (a × b) + (a × c) and (a + b) × c = (a × c) + (b × c) for all a,b,c in A (distributivity)

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 4 to 2. If he wants to use a total of 102 cans, how many cans of green beans should he use?
Using the ratios we know that out of 102 cans, 34 cans will be of green beans that John will use.
What is the ratio?In mathematics, a ratio shows how frequently one number appears in another.
For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.
Oranges make up 8:14 of the total fruit, whereas lemons make up 6:8 of the total fruit.
If you enter this into a calculator, the result will come out as 0.6 decimal.
In other words, 3/5 is equal to any two numbers that divide to provide the same result.
So, the total cans that John wants to use:
102
Then, the ratio of pumpkin to green beans:
4:2
Sum: 4+2 = 6
Then, out of 102 cans, the cans of green beans would be:
= 102 * 2/6
= 102 * 1/3
= 34
Therefore, using the ratios we know that out of 102 cans, 34 cans will be of green beans that John will use.

The surface area of the cylinder is approximately 951.44 square inches, rounded to the nearest hundredth.
What is the surface area of the cylinder?
To find the surface area of a cylinder, we need to find the sum of the areas of its curved surface (lateral area) and its two circular bases.
The formula for the lateral area of a cylinder is L = 2πrh, where r is the radius and h is the height. The formula for the area of each circular base is B = πr^2.
We are given that the height of the cylinder is 11 inches and the radius is 8 inches. Therefore, we can calculate:
L = 2πrh = 2 × 3.14 × 8 × 11 = 549.52 in²
B = πr^2 = 3.14 × 8^2 = 200.96 in²
The total surface area is the sum of the lateral area and the two base areas:
Surface area = L + 2B = 549.52 + 2(200.96) = 951.44 in²
Hence, the surface area of the cylinder is approximately 951.44 square inches, rounded to the nearest hundredth.

a mug slides across a horizontal counter with initial speed v. it slides off the 0.86 m high counter and lands 1 m from the base. what was its initial speed?
slides off the 0.86 m high counter and lands 1 m from the base. what was its initial speed ⇒ Ø = 56.87˚ beneath the horizontal
A. Suppose the horizontal component of the velocity is vx and the vertical is vy.
At first at t=0 (as the mug leaves the counter) the components are v0x and v0y.
v0y = 0 since the customer slides it horizontally so applied force is in the x component as it were.
The equations for horizontal and vertical shot movement are:
x = x0 + v0x t
y = y0 + v0y t - 1/2 g t^2 = y0 - 1/2 g t^2
Setting the beginning to be the end corner of the counter so that x0=0 and y0=0, thus:
x = v0x t
y = - 1/2 g t^2
Given esteem are: x=1.50m and y=-1.15m (y is negative since mug is going down)
1.50m = v0x t - - - - > v0x= 1.50/t
-1.15m = - (1/2) (9.81) t^2 - - - - - > t =0.4842 s
Working out for v0x:
v0x = 3.10 m/s
B. v0x is constant since there could be no other horizontal forces so, v0x=vx=3.10m/s
vy can be calculated from the recipe:
vy = v0y + at where a=-g (negative since going down)
vy = - gt = - 9.81 (0.4842)
vy = - 4.75 m/s
Presently to get the point beneath the horizontal, tan(90-Ø) = - vx/vy
