Answer:
Answer is 88
Step-by-step explanation:
We have Given function
we have to find f'(x) at x=3 Where f'(x) shows derivative of the given function.
This means we need
f'(3)=?
So By definition of the Derivative that is
so this our definition of derivative of the function
Now We have to find out at x=3, So By putting x =3 in definition ,We get
f'(3)=lim(h---->0)(f(3+h)-f(3))/h
Here lim(h--->0) means limit h approaches to zero(right arrow 0limh→0)
=lim(h---->0)((88(3+h)-77))-(88(3)-77))/h
=lim(h---->0)((264+88h-77)-264+77)/h
=lim(h----->0)(264+88h-77-264+77)/h
now by performing simple arithematic we get result
f'(3) = lim(h---->0)(88h/h)
f('3) = lim(h---->0)(88)
here we use law of the limit we limit of the constant is that constant
lim(h----->0)c=c
so
f'(3)=88
So this our answer
A) Let C = Total cost
C = 1.085
b/c) - you need the price of the product you are buying
Answer:
24 chairs in each class needed
25 classrooms
700 chairs total
how many extra chairs
chairs will be c
t is total
t= 25×c
opposite of multiplication is division( 25 is multiplying by c) c needs to be alone
25 classrooms times chairs equal total chairs
t is 700
700=25×c
700/25=25/25c
700/25=C
c is 28
so 28 chairs for 25 classrooms
they need 24 chairs per class
so there are 4 extra chairs per class
4×25 is 100
**or just multiply 25 classes and 24 chairs
25 times 24 is 600
there are 700 chairs
100 left over
so 100 extra chairs
Answer:
14 miles per hour
Step-by-step explanation:
The average speed would be the total distance divided by the total time = 35 miles divided by 2.5 hours is 14 miles per hour
Answer:
12.50 ft per hour
Step-by-step explanation:
Given that:
Fish pond has a rectangular shape.
Length of fish pond = 60 feet
Width of fish pond = 40 feet
Total time to complete the fencing = 16 hours
To find:
Unit rate of putting the fencing around the fish pond.
Solution:
First of all, we need to find the total fencing to be put around the fish pond.
Total fencing is nothing but the perimeter of the fish pond which is of rectangular shape.
Formula for perimeter of rectangular shape is given as:
Unit rate is the perimeter divided by total time taken to put the fencing around.
Therefore,
Unit rate = 
feet per hour
So, the answer is <em>12.5 feet per hour</em>.
