Write an equation of a line perpendicular to the line ax + by = c that passes through the point (-1,2).

baherus [9]

Answer:

Step-by-step explanation:

line perpendicular to ax+by=c is

bx-ay=k, where k is a constant.

if it passes through (-1,2) then

b(-1)-a(2)=k

or k=b-2a

so reqd. eq . is bx-ay=b-2a

If 90 is 60% of N, then what does N equal?

sertanlavr [38]

Answer:

150

Step-by-step explanation:

The 100% of a number is represented by N and 60% of N = 90

To find the whole we multiply 90 with 100 and divide that by 60

100*90/60 = 150

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

$dP_g = [\frac{dg}{g}] P$

Use the sample data and confidence level given below to complete parts (a) through (d).

Readme [11.4K]

Answer:

Step-by-step explanation:

yes because 3+2 +5 = 923x which is the inversde ratio of a triangle. This leads us to 1 half of 3.14, once we have 3.14, divide it by 70594. Now, you get 59.4.

Hope this helped!
