Find the output for each input of y = 2x – 1.

1 answer:

5 0

1) False. You'd substitute -1 in for x, not y.
2) The scale factor is 1ft=14ft so true.
3) The first is a direct variation since y=6x is true.
4)The airplane would be 132ft in real life.
5) None of the functions made sense with the graph. I didnt really know what "thing" you were talking about on that one.

the graph of y=e^tanx-2 crosses the x axis at one point in the interval [0,1]. What is the slope of the graph at this point? I g

Y = e^tanx - 2

To find at which point it crosses x axis we state that y= 0

e^tanx - 2 = 0
e^tanx = 2
tanx = ln 2
tanx = 0.69314
x = 0.6061

to find slope at that point first we need to find first derivative of funtion y.

y' = (e^tanx)*1/cos^2(x)

now we express x = 0.6061 in y' and we get:
y' = k = 2,9599

If 2L of solution needs to be administered through an IV over 24hours, then how many mililitres of solution needs to be provided

kow [346]

Answer:

83.33 milliliters

Step by step explanation:

2L = 2000 ml Change the liters to milliliters first

2000 ml : 24 hours

x ml : 1 hour

Next you cross multiply : 2000 × 1 hour = 2000 and 24 × x = 24x

Then you divide:

$\frac{24x}{24} : \frac{2000}{24}$

x : 83.3333333...

When this is rounded off it is equal to 83.33
