3a. False
3b. False
3c. False
3d. True
4. C
Step-by-step explanation:
I think this is right but I'm not sure, this is some tough stuff.
Good luck!
Your Universe is D, set B ={swimmers}, set C = {weightlifters}.
First, you are looking for what is either swimmers or weightlifters and that is given by the union of sets B and C: B∪C
Then, you have to look for everything that is not swimmers or weightlifters, and that is the complement of the previous set: ¬(B∪C)
An other notation could be everything that is in the Universe which is not a swimmer or a weightlifter: D - (B∪C)
The area will be therefore the one outside the circles.
Answer:
23
Step-by-step explanation:
Use the hint to solve!
New equation would be 49 = 26 + h.
49 - 26 = 23.
Holly has 23 barrettes.
Answer:
The height is 20
The max profit is 1600
Step-by-step explanation:
P (h) = -4h^2 + 160h
The vertex is at
-b/2a = -160/2(-4) = 160/8 = 20
The height that will give the maximum profit is 20
We want to find the value at 20
P(40) =-4(20)^2 +160(20)
=-1600+3200
1600
5x+130=8x+151
subtract 5x from each side
5x-5x+130=8x-5x+151
130 = 3x+151
subtract 151 from each side
130-151 =3x
-21 = 3x
divide by 3
-21/3 = 3x/3
-7 =x
