From Wikipedia: Blood pressure (BP) is the pressure exerted by circulating blood on the walls of blood vessels, and is one of the principal vital signs. During each heartbeat, BP varies between a maxi
y=x^2 and y=5x-6
:/-Its best to use substitution here. Both equations are equal to y so
x^2 = 5x - 6
Rearrange to 0
x^2 - 5x + 6 = 0
Solve by factorising
(x-3)(x-2) = 0
x = 3 or 2
When x=3, y=

suppose the fuel consumption cost is $25 per unit. Give a point estimate (single value) for the change in the average cost of fuel per mile for each additional rail car attached to a tr
Pretty much weve been given four equations.
1. y= 2x^2 -7x - 3
2. y= -3x^2+6x-1
3. y= x^2+x+4
4. y= 4x^2 -12x + 9
Weve also been given four graphs and told to match them. Looking at the equations
okay... ijust want to double check...
These are my choices:
1.25
0.065
25
... imultiplied 5 times 5... got 25.. then I multiplied by 0.5... and got 12.5...
is it the correct way of doing it??? ... a
(that is within the rigour of a first year linear algebra course)-Yeah, that sounds right. If I have my terms correct, linear dependency means theyre all in the same direction. So a formal proof would
The question is find the derivative of f(x)= (x-2)(x-3)^3
I used the product rule:
so f (x) = (x-2) d/dx(x-3)^2 + (x-3)^2 d/dx(x-2)= (x-2)(d/dx x^2 - 6x + 9) +(x-3)^2 (1)= (x-2)(2x -6) + x^2 - 6x +9=
the numbers 1 to 2011 are written side by side as follows 1234 ............... 20102011 . if the number is divided by 9, then what is the remainder?
A) 0
B) 1
C ) 2
D ) 3-There is a theorem that say
-y=2x and 3x+y=20-from
-y=2x
y=-2x
then youll substitute to this
3x+(-2x)=20
x=20
y=-2(20)
=-40
to check youll just substitute the answers you got to the original eq then if the result is eq then yo
A paper box has a capacity of 320cm^3 and the base of the box is a square. The height is 5 cm. What is the length of the box?
my answer is 8 is it correct
thanks-correct.-5x^2 = 320
x^2 = 64
x = 8 cm
I was struggling with this equation...
1/3n + 1/4n = 7/24
Ive now realised I had to add the first two terms to get 7/12n, but I was originally trying to multiply the entire equation by the LCM which
An employee makes up a compost by mixing 3 parts peat with 1 part sand.
He mixes 24 kilograms of this compost.
How much peat does he need?
For some reason I cant figure out how to do primary school m
I have the probability (p1) that the number of successes in a repeated experiment (binomial probability n- repetitions) is at least K.I also have the probability of success in a single experiment (p).
Let g(x)=x^6-8 ϵ Z[x]
i) Factor g(x) into irreducibles over R
ii) Factor g(x) into irreducible over Q
iii)Show that E= Q(sqrt(-3),sqrt(2)) is the splitting field of g(x) over Q.
iv) Identify up to is
