What is velocity?The change of displacement with respect to time is defined as Velocity. velocity is a vector quantity. It is a time-based component. Its standard unit is m/sec.
Given that the position of an object at time t is given by s(t) = 1 - 12t. Therefore, the velocity of the object can be written as,
V = ds/dt
= d(1 - 12t)/dt
= -12
s'(t) = -12
Now, the instantaneous velocity at t=2 is,
s'(2) = -12
Hence, the instantaneous velocity at t = 2 is -12.

Kathy Beckhardt weighs four of her sheep at the fair. She can weigh two of them at a time on the big scale. Sheep A and sheep B have an average weight of 150 pounds, sheep B and sheep C have an average weight of 127 pounds, and sheep C and sheep D have an average weight of 168 pounds. What is the average weight of sheep A and sheep D?
Using a system of equations, it is found that the average of sheep A and sheep D is of 191 pounds.
What is a system of equations?
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are the weights of the sheep, given by A, B, C and D.
Sheep A and sheep B have an average weight of 150 pounds, hence:
[tex]\frac{A + B}{2} = 150[/tex]
A + B = 300 -> B = 300 - A
Sheep B and sheep C have an average weight of 127 pounds, hence:
B + C = 254
300 - A + C = 254
C - A = -46.
A - C = 46.
C = A - 46.
Sheep C and sheep D have an average weight of 168 pounds, hence:
C + D = 336
A - 46 + D = 336.
A + D = 382.
The average weight of sheep A and sheep D in pounds is:
[tex]\frac{A + D}{2} = \frac{382}{2} = 191[/tex]

Using compound interest formula,
[tex]A = p(1 + \frac{r}{n} )^{nt}[/tex]
where
p = principalr = raten = number of timest = timeTherefore,
p = 30,000
r = 3.5% = 0.035

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for each burrito.
Money made from selling burritos is positive. The cost of making burritos is negative. Profit is the money left after paying the costs.
How much profit would the restaurant make by selling 100 burritos?
Answer these questions to find out.
1. How much money would the restaurant take in by selling 100 burritos
Answer:
1. How much profit would the restaurant make by selling 100 burritos?
Answer: The restaurant would make $550
2. How much money would the restaurant take in by selling 100 burritos
Answer: The restaurant would take in $800
Step-by-step explanation:
First we have to add all the negatives.
-1.50 + -1.00
= -2.50
Now that we have that, we just need to multiply both the 8 dollars and the -2.50 by 100.
8 * 100 = 800
-2.50 * 100 = -250
Now we have the answer for the second question.
The restaurant would take in $800 before the cost of the ingredients.
But now we need to find the profit. (Which is the amount of money they made minus the cost of the ingredients and meat)
800 - 250 = 550
So the restaurant will make $550 in profit.
Hope this helped! :D

City planners are planning to build a new community park. They agree that the park will be rectangular in shape, but the proposed
dimensions changed. At the most recent meeting, it was determined that the length would remain at 21.6 meters but that the width
would increase by 4.7 meters. So, the park would now cover an area of 714.96 square meters.
Which equation can be used to determine the original width of the park?
Answer:
(c) 714.96 = 21.6(w +4.7)
Step-by-step explanation:
The area of the rectangular park will be the product of its length and width. This relation is used to write an equation to find the original width of the park.
WidthLet w represent the original width of the park in meters. The new width is 4.7 meters more, so is represented by (w +4.7).
Other dimensionsThe length of the park is given as 21.6 meters. The area is given as 714.96 square meters.
Area formulaThe various dimensions of the park are related by the area formula:

If cos a = 0.871 and cos ß= 0.338 with both angles' terminal rays in Quadrant-I, find the values of
tan(a + 3) =
Your answers should be accurate to 4 decimal places.
Answer:
tan(α+β) ≈ -5.8688
Step-by-step explanation:
You can use the formula for the tangent of the sum of angles, or you can use a calculator to find the angles. The latter is much simpler.
Calculator solutiontan(α+β) = tan(arccos(0.871) +arccos(0.338))
tan(α+β) ≈ -5.8688
Note that the two angles total slightly more than 90°, so the tangent of their sum is a large negative number.
Trig identity solutionThe use of trig identities also requires a calculator, and many more steps.
The tangent of the angle can be found from the cosine using ...
tan(x) = √((1/cos(x))² -1)
tan(α) = √((1/0.871)² -1) ≈ √(1.1481056² -1) ≈ 0.56404479
tan(β) = √((1/0.338)² -1) = √(2.9585799² -1) ≈ 2.7844559
And the tangent of the sum of angles is ...
tan(α +β) = (tan(α) +tan(β))/(1 -tan(α)tan(β))
tan(α+β) = ((0.56404479 +2.7844559)/(1 -(0.56404479)(2.7844559))
tan(α+β) = 3.3485007/(1 -1.5705579)
tan(α+β) ≈ -5.8688

The approximate angles are ...
α ≈ 29.4249°
β ≈ 70.2448°
