Elanso [62]
(0,346)(2,344.8)
slope = (344.8 - 346) / (2 - 0) = -1.2 / 2 = -0.6

y = mx + b
slope(m) = -0.6
(0,346)...x = 0 and y = 346
now we sub and find b, the y int
346 = -0.6(0) + b
346 = b
so ur equation is : y = -0.6x + 346....with x being the number of weeks

after 4 weeks...
y = -0.6(4) + 346
y = - 2.4 + 346
y = 343.6 <==== after 4 weeks

after 9 weeks..
y = -0.6(9) + 346
y = -5.4 + 346
y = 340.6 <=== after 9 weeks

Katarina [22]
Assuming that means 1.10^t:

0.10 is for years. To get months divide by 12.
0.10/12 = 0.0083333... 
And (1+0.083333...) = 1.0833333. (You will have to multiply t by 12 also to get it in terms of months)

3 feet of snow fell in 1 2/3 hours. What was that rate in inches per hours?
dalvyx [7]

Answer:

21 \frac{3}{5}in/hr

Step-by-step explanation:

Distance of snow fall  = 3ft

Time taken  = 1\frac{2}{3}hrs

Unknown:

Rate of snowfall = ?

Solution:

The rate of the snowfall is the same as the speed of the fall;

  Rate of snowfall  = \frac{distance of snowfall}{time}

Convert the ft to inches;

             1ft  = 12inches

             3ft  = 3 x 12  = 36inches

Input the parameters and solve;

           Rate of snowfall  = \frac{36}{\frac{5}{3} }   = 36 x \frac{3}{5} = 21 \frac{3}{5}in/hr
