Answer:
Step-by-step explanation:
You are going to integrate the following function:
(1)
furthermore, you know that:
lets call to this integral, the integral Io.
for a general form of I you have In:
furthermore you use the fact that:
by using this last expression in an iterative way you obtain the following:
(2)
with n=2s a even number
for s=1 you have n=2, that is, the function g(x). By using the equation (2) (with a = 1) you finally obtain:
Let's say that y is the unknown
180=2x+3+5x+1+y
180=7x+4+y
180-7x-4=y
176-7x=y=third angle
Answer: 150 students walk to school
Step-by-step explanation: 75%=0.75
200 multiplied by 0.75
200×0.75=150 students
Or
75%=3/4
3/4 of the children walk to school
3/4×200=3/4×200/1=150
I guess the error is in the calculus.
-1/4 divided by 3/2:
(-1/4)/(3/2): When dividing 2 fractions, its answer is equal to the first fraction multiplied by the inverse of the second.
(-1/4)/(3/2) = -1/4 * 2/3 = -2/12
So -1/4 divided by 3/2 is different from -4/1 multiplied by 3/2.
-1/4 divided by 3/2 = -1/4 multiplied by 2/3.
Hope this Helps! :)
