So this is what i did but im not sure if its 100% correct

585 / 9 to get the number of groups = 65

then you take 65 x 3 for number of students in each group and you get the final answer of 195 students

Answer:

195 students.

Step-by-step explanation:

Each group of three created (or used) 9 pictures.

So that means three pictures per student.

Dividing 585 students by 3 pictures per student means that there are

585/3 = 195 students.

Verify that the function satisfies the three hypotheses of Rolle's Theorem on the given interval. Then find all numbers c that s
valkas [14]
<h2>Answer with explanation:</h2>

Rolle's Theorem states that:

If f is a continuous function in [a,b] and is differentiable in (a,b)

such that f(a)=f(b)

Then there exist a constant c in between a and b i.e. c∈[a,b]

such that:  f'(c)=0

Here we have the function f(x) as:

f(x)=4x^2-8x+3 where x∈[-1,3]

  • Since the function f(x) is a polynomial function hence it is continuous as well as differentiable over the interval [-1,3].

Also,

f(-1)=15

(Since,

f(-1)=4\times (-1)^2-8\times (-1)+3\\\\f(-1)=4+8+3\\\\f(-1)=15   )

and f(3)=15

( Since,

f(3)=4\times 3^2-8\times 3+3\\\\f(3)=36-24+3\\\\i.e.\\\\f(3)=15 )

  • i.e. f(-1)=f(3)

Hence, there will exist a c∈[-1,3] such that f'(c)=0

f'(x)=8x-8\\\\i.e.\\\\f'(x)=0\\\\imply\\\\8x-8=0\\\\i.e.\\\\x-1=0\\\\i.e.\\\\x=1

Hence, the c that satisfy the conclusion is: c=1

How do you find slope?
Tresset [83]

Answer:

Step-by-step explanation:

If you try to find a line (linear) slope between two points (x,y) and (x',y')

the slope or ratio of change : m = difference of y / difference of x

or m= ( y - y') / (x - x')

In a linear equation like y = mx + b ... m is the slope
