Step-by-step explanation:

An easy-ish way to graph something in slope-intercept form is to use the y-intercept and the slope because that info is given.

the y -int is when x = 0 and then y would equal -1/2. (0,-1/2)

then the slope is 3/4 which is rise over run so go three up (rise) and 4 across (run). make sure that your line has a positive slope ( / ) because the slope is positive in the equation, not negative ( \ )

You now have 2 points. Draw a line connecting the two points.

Use the site called Desmos, it's a graphing calculator and should help you in all the ways you need. It isn't complex. Just put that equation in a box and it graphs it for you.

where p0 is the atmospheric pressure at sea level and k is a constant. If the atmospheric pressure is 14.7 lb/in.2 at sea level

balu736 [363]

Answer:

The value of pressure at an altitude of 10000 ft = 10 $\frac{lb}{in^{2} }$

Step-by-step explanation:

Given data

Atmospheric pressure $P_{0}$ = 14.7 $\frac{lb}{in^{2} }$

Pressure at 4000 ft = 12.6 $\frac{lb}{in^{2} }$

If temperature is constant then the atmospheric pressure is varies with the altitude according to law

P (h) = $P_{0}$ $e^{- kh}$ ------ (1)

where k= constant & h = height

12.6 = 14.7 $e^{- 4000k}$

0.857 = $e^{- 4000k}$

㏑ 0.857 = - 4000 k

-0.154 = - 4000 k

k = 3.85 × $10^{-5}$

Thus the atmospheric pressure at an altitude of 10,000 ft is

$P_{10000} =$ 14.7 × $e^{- kh}$ ----- (2)

Product of k & h is

k h = 3.85 × $10^{-5}$ × 10000

k h = 0.385

Put his value of k h = 0.385 in equation (2) we get

$P_{10000} =$ 14.7 × $e^{-0.385 }$

$P_{10000} =$ 10 $\frac{lb}{in^{2} }$

This is the value of pressure at an altitude of 10000 ft.

Adding unlike fractions<br><br> 1/15+38/100

Daniel [21]

Answer:

134/300 or 67/150

Step-by-step explanation:

the LCM of 15 and 100 is 300. 15 *20 is 300 so we multiply both the numerator and denominator of 1/15 by 20 to get 20/300, with 38/100 we multiply by 3 to get 114/300. Now we add 20/300 and 114/300 to get 134/300 which has a common factor of 2 so we can simply it to 67/150
