scientific notation value for (2.35E6)(-3.7E-3)

Why didn't you just do it on your calculator? I just tried to do it on mine and I will admit I kept getting error messages.

(2.35E6)(-3.7E-3)
= -2.35*3.7 * 10 ^6-3
= -2.35*3.7 * 10 ^6-3
= -8.695 * 10 ³

heparin drip is to be started at 12units/kg./hr. Patient weighs 180 pounds. How many units will be infusing?

1kg = 2.20462 pounds

180 pounds = 180 / 2.20462 = 81.6467 Kg (4dp)

12units/kg * 81.6467 Kg = 979.67 units per hour

I have 1 angle and 2 lenghs what do i do? i need the other lengh
I am assuming that you are talking about a triangle.
If you have the included angle you use the cosine Rule
If you don't have the included angle then you need more informations.

4k+mn=n-3;n solve n 3ab-2bc=12;c solve c z=(x+y/3)w;y

I don't understand your notation.
Are these 3 separate questions?

Do you mean ?

a) 4k+mn=n-3 Make n the subject

b) 3ab-2bc=12 Make c the subject

c) z=(x+y/3)w Make y the subject

There is no answer because the square root of a negative number does not exist (not in the 'real' world anyway)

When you get this as an answer to a quadratic equation it means there is no solution.

Joan drive 333.5 miles before she has to buy gas. Her cargets 29miles per gallon. How many gallons of gas did the car star out with ?
Put the fractions upright and try and think about what I am saying
units in fractions can cancel out the same as numbers can

miles/1 * gallons/miles = gallons (because the miles cancel out)
and
29miles per gallon = 29miles/1gallon

If you can go 29 miles on 1 gallon of petrol then
1 gallon of petrol will take you 29miles

So if the rate is 29miles/1gallon it is equivalent to say that the rate is 1gallon/29miles

333.5miles * 1gallon/29miles = 333.5/29 gallons ( the miles cancel out)

I sure other forum users will look at this and say I made a huge deal out of a little problem.
This is true, but if you master this method of dealing with rates you can do all sorts of very difficult rate problems.

Hi, I'm in Calculus class and I wanted to know how to answer this question - The distance from one side of the stadium is 756.7 kilometers and 18518235.78 millimeters. 7m/34s is how fast Eric ran the race. What was his time?

18518235.78 millimeters = 18518.23578m = 18.51823578 km
756.7 kilometers This must be a stadium for volcanos to play on. A volcano is the only animated thing that seems big enough. lol
The numbers in your question simply don't make sense.

Q= 25(1/2)^t/1620
determine the initial quantity when t=0

Q= 25*(1/2)^t/1620
sub in 0 to t
Q= 25*(1/2)^0/1620
Anything to the power of 0 is 1
Q= 25*1/1620
Q= 25/1620

csc(tan^-1(10/9))

Draw a right angled trianle
mark one of the acute angles as theta
let
theta = inv tan (10/9)
that is
tan (theta) = 10/9
put 10 on the opposite side and 9 on the adjacent side
Use pythagoras theorem to find the hypotenuse
cosec=1/sin = hyp/opp
csc(tan^-1(10/9)) = sqr(181)/9

How do you write 1 over 10000 as a decimal?

1/10 is 0.1
1/100 is 0.01
1/1000 is 0.001
do you see where I am going with this?
