Sergeu [11.5K]
3 periods....20 minutes each.....3 * 20 = 60 total minutes playing time
colin plays 12 minutes each period...12 * 3 = 36 minutes 

Collins playing time to total playing time = 36/60 reduces to 9/15 or 9:15 or 9 to 15 <===

In which order should you look for assistance with college expenses?
lyudmila [28]
The correct answer should be Choice B. 

Scholarships and merit aid are the best way to earn money to go to college. They don't have to be paid back. When it comes to loans, you should select federal before non-governmental because the interest rates are usually lower on federal loans.

Write an exponential function in the form y=ab^x that goes through points (0, 18) and (2, 288)
Ede4ka [16]

y = abx

Point (1, 4): 4 = ab

Point (3, 16): 16 = ab^3

From 4=ab we have a = 4/b

Substitute into 2nd equation

16 = (4/b)b^3

16 = 4b^2

4 = b^2

2 = b

a = 4/b = 4/2 = 2

An exponential function that fits is: y = 2(2^x)

check: x=1; y = 2(21) = 4 ... point (1, 4)

x=3: y = 2(23) = 2(8) = 16 ... point (3, 16)

Given P space equals space P subscript 0 space plus space rho g h, your objective is to determine the uncertainty of P by measur
son4ous [18]

Answer:

the g's contributing term for the overall uncertainty of P is  dP_g =  [\frac{dg}{g}]

Step-by-step explanation:

From the question we are told that

   The pressure is   P  = P_o + \rho gh

The first step in determining the uncertainty of P in by obtaining the terms in the equation contributing to it uncertainty and to do that we take the Ln of both sides of the equation

    ln P  = lnP_o + ln(\rho gh )

=>   ln P  = lnP_o + ln \rho + ln g  + ln h

Then the next step is to differentiate both sides of the equation

    \frac{d(ln P)}{dP}  =  \frac{d(ln P_o)}{dP_o} + \frac{d(ln \rho)}{d\rho} +\frac{d(ln g)}{dg} + \frac{d(ln h)}{dh}

=>    \frac{dP}{P}  =  \frac{dP_o}{P_o} + \frac{d \rho}{\rho} +\frac{d g}{g} + \frac{d h}{h}

We asked to obtain the contribution of the term g to the uncertainty of P

This can deduced from the above equation as

     dP_g =  [\frac{dg}{g}] P
