Answer:
1.5
Step-by-step explanation:
the slope is regarded as :
=
this is also known as the <em>gradient </em>, meaning the differences of two y values divided by the differences of the two corresponding x values
take two values on the slope and put in the form ( x,y)
we shall use two points A and B
A = (80 , 100)
B = (20 , 10)
now use the formula:
=
=
also can be represented into an integer form
answer is <u>1.5</u>

Answer:
Step-by-step explanation:
This is a Combination (as in permutation vs combination) question the symbol (n r) refers to "n choose r". This is sometimes written as nCr
i.e the question is asking you to find how many combinations each will yield when you chose r items from n item without repetition and order does not matter.
I will only do the first question for you and you can just follow the same steps to solve the rest of the questions.
Recall that
Consider question a) we are given (5 1) or ₅C₁
we can see that n = 5 and r = 1
If we substitute this into the formula:
₅C₁ = (5!) / [ (1!)(5- 1)!]
= (5!) / [ (5- 1)!]
= (5!) / (4!)
= (5·4·3·2·1) / (4·3·2·1)
= 5
hence ₅C₁ = 5
The answer is C. 89 in^2
This is found by (1/2(
))+70
r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5
You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.
Hope this helps!
