X^5(1-x)^6<br> How to find the critical points

Lana71 [14]

$y=x^5(1-x)^6\\
y'=5x^4(1-x)^6+x^5\cdot6(1-x)^5\cdot(-1)\\
y'=x^4(1-x)^5(5(1-x)-6x)\\
y'=x^4(1-x)^5(5-5x-6x)\\
y'=x^4(1-x)^5(5-11x)\\\\
x^4(1-x)^5(5-11x)=0\\
\boxed{x=0 \vee x=1 \vee x=\dfrac{5}{11}}$

Of the 60 students in a school, 24 are currently studying chemistry. Exactly 16 of the girls in the school are not currently stu

garri49 [273]

Answer:

7 boys.

Step-by-step explanation:

Given:

Total number of students in the school = 60

Total number of girls in the school = 33

Total number of students currently studying chemistry = 24

Total number of girls not currently studying chemistry = 16

<u>Question asked:</u>

How many boys are currently studying chemistry ?

Solution:

<u>Total number of girls in the school = 33</u>

Total number of girls not currently studying chemistry = 16

Total number of girls currently studying chemistry = Total number of girls in the school - Total number of girls not currently studying chemistry

Total number of girls currently studying chemistry = 33 - 16 = 17

Now:-

<u>Total number of boys and girls currently studying chemistry = 24</u>

Total number girls currently studying chemistry = 17

Total number of boys currently studying chemistry = Total number of boys and girls currently studying chemistry - Total number girls currently studying chemistry

Total number of boys currently studying chemistry = 24 - 17 = 7

Therefore, 7 boys are currently studying chemistry.

if a rectangle's length is 2 x − 1 and the width is 4 x − 2 , write an expression for the perimeter and an expression for the ar

miskamm [114]

Answer:

Step-by-step explanation:

2p/2 = 2x+7

1) 2x+7 -x - 5 =

width = x + 2

2) 2p/2 = 21 in

x + 5 + x + 2 = 21

2x = 14

x = 7

lenght = 7 + 5 = 12 in

width = 7 + 2 = 9 in

3 )

A = (x+5)(x+2)

4)

A = 12 x 9 = 108
