area of shaded figure = l x w = 24 *18 = 432
area of white square = 12*12 = 144
area of shaded part = 432-144 = 288 m^2
Answer is A
I believe you meant f(x) = x^2 - 3x - 10.
f(b) - f(a)
The ave. r. of c. formula is a. r. c = -----------------
b -a
(6)^2 - 3(6) - 10 - [(4)^2 - 3(4) - 10]
Here, a. r. c. = ------------------------------------------------------
6-4
36 - 18 -10 - 16 + 12 + 10
... which comes out to ---------------------------------------
2
a. r. c. = 7 for x^2 - 3x - 10 on the interval [4,6]
We are given statements : Premise: If the sides of a triangle are all 4 cm, then the triangle is equilateral.
Premise: The triangle is equilateral.
According to law of Detachment : Statement 1: If q, then q.
and Statement 2: p
Conclusion: q.
According to given reasoning :
p : If the sides of a triangle are all 4 cm.
q : Then the triangle is equilateral.
Therefore, Statement 1 : If( the sides of a triangle are all 4 cm), then (the triangle is equilateral).
Statement 2: (the triangle is equilateral).
Conclusion : The sides of the triangle are 4 cm.
Therefore, option B is correct "Law of Detachment".
Max mows a yard in 45 minutes and Jan takes twice as long mowing the same yard. If Max and Jan both work together, it will take approximately 30 minutes to for them both to mow the yard.
It take Max 1 minute to mow 1/45 of the yard.
It takes Jan 1 minute to mow 1/90 of the yard.
1/45+1/90 =3/90 = 1/30 of the yard can be mowed by both in just one minute. This is how to get the answer, 30 minutes.
