An airplane lands on a runway with a velocity of 150 m/s. How far will it travel until it stops if its rate of
deceleration is constant -3m/s2?
Answer:
3750 m
Step-by-step explanation:
This question can be solved using law of equation of motion
[tex]v^2 = u^2 + 2as[/tex]
where v is the final velocity
u is the initial velocity
a is the acceleration
and
s is the distance travelled
________________________________
given
final velocity = v = 0 since it is given that plane stops
u = 150 m/s
a = -3m/s2
using the above values in the given equation
[tex]v^2 = u^2 + 2as\\0 = 150*2 + 2*-3s\\0 = 22500 - 6s\\=> 6s = 22500\\=> s = 22500/6 = 3750[/tex]
Thus, plane will travel 3750 m before it stops.
The demand equation for the Drake GPS Navigator is x + 4p − 848 = 0, where x is the quantity demanded per week and p is the wholesale unit price in dollars. The supply equation x − 20p + 1000 = 0, where x is the quantity the supplier will make available in the market each week when the wholesale price is p dollars each. Find the equilibrium quantity and the equilibrium price for the GPS Navigators.
Given:
Demand equation : [tex]x+4p-848=0[/tex].
Supply equation : [tex]x-20p+1000=0[/tex]
To find:
The equilibrium quantity and the equilibrium price for the GPS Navigators.
Solution:
Demand equation is
[tex]x+4p-848=0[/tex]
where x is the quantity demanded per week and p is the wholesale unit price in dollars.
Quantity demanded [tex]=x=848-4p[/tex] ...(i)
Supply equation is
[tex]x-20p+1000=0[/tex]
where x is the quantity the supplier will make available in the market each week when the wholesale price is p dollars each.
Quantity supplied [tex]=x=-1000+20p[/tex] ...(ii)
For equilibrium, Quantity demanded = Quantity supplied.
[tex]848-4p=-1000+20p[/tex]
[tex]848+1000=4p+20p[/tex]
[tex]1848=24p[/tex]
Divide both sides by p.
[tex]\dfrac{1848}{24}=p[/tex]
[tex]77=p[/tex]
Substitute p=77 in (i), to find the equilibrium quantity.
[tex]x=848-4(77)[/tex]
[tex]x=848-308[/tex]
[tex]x=540[/tex]
Therefore, the equilibrium quantity is 540 units per week and the equilibrium price is $77 for the GPS Navigators.

Use this method to estimate the students who attend your school (or a certain building on your campus) on a given morning. Count the number of students entering the building in 1 minute and multiply this number by the minutes it takes the entire group to enter.
Answer and explanation:
The data we get from counting how many people entering a building in one minute is the sample of the population size. We do this since it would be tedious or not feasible to stand and count one by one how many people enter the building and so we do a good estimate with our one minute sample
Let's assume in one minute, 15 people enter the building and it takes one hour for everyone to enter the building
Population size would be 15*60 minutes= 900 people
AA and BB are n×nn×n matrices. Check the true statements below: A. If two row interchanges are made in sucession, then the determinant of the new matrix is equal to the determinant of the original matrix. B. The determinant of AA is the product of the diagonal entries in AA. C. detAT=(−1)detAdetAT=(−1)detA. D. If detAdetA is zero, then two rows or two columns are the same, or a row or a column is zero.
Answer:
If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matrix. ( A )
Step-by-step explanation:
A and B been n*n matrices the true statement would be ; If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matrix.
Although other options can be true for some matrices but they are not always true for every kind matrices but option A is always true

Mike ran 1/2 of a mile in 10 minutes if he continues at this rate how far did Mike run in one hour
Answer:
3 miles
Step-by-step explanation:
bc he ran .5 a mile in 10 minutes. an hour is sixty minutes, so 10x six. then you do .5 x six to get 3.
If x = 4 and y = 7 , evaluate the following expression: 20 + 2 ( 3 y − 4 x )
If x = 4 and y = 7 of the following expression: 20 + 2 ( 3 y − 4 x ) then it will gives 30.
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple.
Given,
If x = 4 and y = 7 ,
the following expression: 20 + 2 ( 3 y − 4 x )
Substitue;
20 + 2 ( 3 y − 4 x )
20 + 2 ( 3(7) − 4 (4) )
20 + 2 (5)
20 + 10

Given m||n, find the value of x.
Answer:
X= 124
Step-by-step explanation:
Because these angles are alternate interior angles we know that X+56 will equal 180, so to solve:
180 - 56= 124
Answer:
124 degrees
Step-by-step explanation:
180 degrees is a straight line
the given angle is 56 degrees
so, all you do is subtract
180 - 56 = 124
to double check,
56 + 124 = 180

Mr. Jones bought a car for $64 000. The car depreciates by 20% in the first year and 10% in each of the following years. The value of the car at the end of the second year was *
Depreciation for 1st year = 20/100 × 64000 = $12800
End of 1st year = $64000 - $12800 = $51200
Depreciation for 2nd year = 10/100 × 51200 = $5120
End of 2nd year = $51200 - $5120 = $46080
Answer:
Value at the end of the 2nd year is $46,080
Answer:
Value at the end of the 2nd year is $46,080
Step-by-step explanation:
Depreciation for 1st year = 20/100 × 64000 = $12800
End of 1st year = $64000 - $12800 = $51200
Depreciation for 2nd year = 10/100 × 51200 = $5120
End of 2nd year = $51200 - $5120 = $46080

The total cost of the trip can be found by adding these components: Entrance fee per student: $5(29) Lunch costs: $4(29 + 6) Bus fees: $25 + 8($2 + $3) Total cost: 5(29) + 4(35) + 25 + 8(5) Which of these are equivalent expressions of the total cost that use the properties of operations to simplify the math? 5(15 + 14) + 4(31 + 4) + 25 + 40 5(20 + 9) + 4(30 +5) + 25 + 40 5(17 + 12) + 4(33 + 2) + 25 + 40 5(19 + 10) + 4(34 + 1) + 25 + 40
Given:
Entrance fee per student: $5(29)
Lunch costs: $4(29 + 6)
Bus fees: $25 + 8($2 + $3)
Total cost: 5(29) + 4(35) + 25 + 8(5)
To find:
The equivalent expressions of the total cost that use the properties of operations to simplify the math.
Solution:
We have,
Total cost = 5(29) + 4(35) + 25 + 8(5)
To simply this expression, we need to write 29 and 35 in the expand form or as the sum of their place values because it is easy to multiply a number with multiply of 10 and single digit.
Total cost = 5(20+9) + 4(30+5) + 25 + 40
Therefore, the correct option is B.

There are 6 triangles and 3 circles. What is the simplest ratio of circles to
triangles?
Answer:
1 : 2
Step-by-step explanation:
The original ratio would be 3 : 6, so now you need to simplify it.
To simplify ratios, you divide the number on each side by their greatest common factor. The GCF(greatest common factor) for 3 and 6 would be 3, so divide 3 by 3 =1 and divide 6 by 3 =2, so then your simplified ratio of circles to triangles would be 1 : 2
Hope this helps! :)
