Answer:
Absolute maximum is 2
Absolute minimum at -2
Step-by-step explanation:
The given parametric functions are:
By the chain rule:
At fixed points,
This gives on
This implies that the extreme points are and
By eliminating the parameter, we have
This is a circle with radius 2, centered at the origin.
Hence (0,2) is an absolute maximum ,at and (0,-2) is an absolute minimum at
So first one
'how many solutions does 2x-y=-5 and 2x+y=5 have?'
add and get
2x-y-5
plus
2x+y=5
equals
2x+2x+y-y=5-5
4x=0
x=0 always
solve for y
4(0)+y=5
y=5
the solution is (0,5)
only <u>ONE </u>solution
one way is to subsitute
just remember that it is in (x,y) form so
the pont (1,2) means that 1 solution is x=1 and y=2 so subsitute and find that
the first one is the answer you are correct
just look at the graph
the solution is the intersection
it seems to be at a point that is 3 units to the right and -6 units up (6 units down)
so the solution is (3,-6)
yo are corect
subsitution
y=y
therefor
the answe ris (-4,-14) if you did the math correctly
#8 is correct
# 9 is correct
# 10 the answe ris bananas=0.40 pears=0.60
the last one you got it wrong, remember to check your answer to the graph for commonsense
then answer is (-2,5) and (1,2)
If you multiply 8.5 by 50 cents your answer will be 4.25
Answer:
A. Yes, because each of the two outcomes are equally likely.
Step-by-step explanation:
A sales representative for a baby food company wants to survey 300 random couples who are new parents to find out if their newborn child is a boy or a girl.
The representative uses a 1 for a girl and a 2 for a boy when running a simulation.
Yes, the simulation will be a fair representation of possible survey results.
A. Yes, because each of the two outcomes are equally likely.
Answer:
The answer to your question is Volume = 32 u³
Step-by-step explanation:
Data
The volume of a rectangular prism = ?
Area of the base = 24
height = 4
Process
1.- Write the formula to calculate the volume of a pyramid
Volume = 1/3 Area of the base x height
2.- Substitution
Volume = 1/3 (24)(4)
3.- Simplification
Volume = 96/3
4.- Result
Volume = 32 u³
