1/2 mile / 1/5 hour = x miles/ 1 hour
using cross products
1/2 * 1 = x * 1/5
multiply by 5 on each side
1/2*5 = x
x = 5/2 miles
x = 2 1/2 miles
Because these triangles are congruent, then angle a is the same degree measure as angle x; angle b is the same as y; and angle c is the same as z. We also know that, because of the Triangle Angle-sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. So for us that means that a+b+c(which is also z) = 180. 50 + 2x + 40 + 4x + 8 = 180. Combining like terms we have 6x + 98 = 180. Subbtracting 98 from both sides gives us 6x = 82 and x = 13 2/3
Answer:
y''=-1.26
Step-by-step explanation:
We are given that 
We have evaluate the second order derivative of y w.r.t. x when x=2 and y=3.
Differentiate w.r.t x
Then , we get




Again differentiate w.r.t.x
Then , we get


Using value of y'


Substitute x=2 and y=3
Then, we get 

Hence,y''=-1.26
