Answer:
J
Step-by-step explanation:
The y-intercept is 3, and the slope is -1/2
Answer:
4777.28 N
Step-by-step explanation:
The gravitational force down the slope is given by the formula;
(mass *g * sin θ )
where;
θ is the angle of inclination of the slope
g is the gravitational pull
We plug in the given values into the above expression;
(4,000 x 9.8 x sin 7) = 4777.28 N.
The frictional force must equal to 4777.28 N (pointing up the slope).
Answer:
-5n + 20
Step-by-step explanation:
n stands for the term number so if you want to find the 50th term all you have to do is substitute n with 50
first of all find the difference between each number in the sequence
the difference between 25 and 20 is -5
the difference between 20 and 15 is -5
the difference between 15 and 10 is -5
the difference between 10 and 5 is minis -5
because
25-5=20
20-5=15
15-5=10
10-5=5
now that you know the the difference you place the number in front of n like this
-5n
to find the rest all you need to do is use the difference between each number which is -5 and do it on the first number
so 25 - 5
this gives 20
so our nth term is -5n + 20
if you still don't get i can re-explain it to you
Step-by-step explanation:
Here :-
- Selling price of 10 mangoes is equal to the cost price of 12 mangoes
![\begin{gathered}\end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%5Cend%7Bgathered%7D)
Let the cost price of one mango be ₹1. So :-
- Cost Price of 10 mangoes = ₹10
- Selling Price of 10 mangoes = ₹12
↝ Here the selling price of 10 mangoes is equal to the cost price of 12 mangoes. It means selling price of 10 mangoes = cost price of 12 mangoes. So, the selling price of 12 mangoes is ₹12 and the cost price of 10 mangoes is ₹10.

<em>Fistly, finding the profit :-</em>

![{\dashrightarrow\sf{Profit = 12 - 10}}](https://tex.z-dn.net/?f=%7B%5Cdashrightarrow%5Csf%7BProfit%20%3D%2012%20-%2010%7D%7D)

∴ The profitis Rs.2.
