Answer:
There needs to be more information. We at least need to know what one of the side measurements for each triangle are. Only then can we give you the answer.
Step-by-step explanation:
Answer:
14.8 miles
Step-by-step explanation:
Ok, so we know from the question that she already lives at least 14 miles away because the bus ride is 14 miles long. So, if she has to walk an extra 0.8 miles, you add them together to get 14.8 :)
<span>dy/dx=xy/3, y > 0 can be rewritten in terms of only one variable (x or y) each:
3 dy
----- = x*dx (first term is all in y; second term all in x).
y
x^2
Integrating, 3 ln y = ------- + ln C, Then ln y^3 = (1/2)x^2 + ln C.
2
Combining the log terms:
ln y^3-ln C = (1/2)x^2.
Given: if x=0, y=4. Subst. these v alues into the equation in y given above:
4^3
ln 4^3 - ln C = (1/2)(0)^2 = 0. Then ln ------- = 0, which tells us that
C
4^3 = C. Thus, the solution is </span>ln y^3 = (1/2)x^2 + ln (4/3).
There are other ways in which you could write this same expression. You could, for example, solve for either y^3 or y alone.
Step-by-step explanation:
the value of x is 4.
The answer to the question is 1.125
