No. the answer is 2^7(because there are seven hours) which equals 128

Math- Differentiation . Could you help me to solve this question?

Arlecino [84]

Answer:

Step-by-step explanation:

Hello, first of all we can find a value for f(1)

$xf(x)+f(x^2)=2 \\\\\text{So for x = 1, it gives}\\\\f(1)+f(1^2)=f(1)+f(1)=2f(1)=2\\\\ f(1) =1$

And we can get the derivative of the equation so.

$(uv)'=u'v+uv' \text{ and } \dfrac{df(x^2)}{dx}=2xf'(x^2) \text{ so we can write}\\\\f(x)+xf'(x)+2xf'(x^2)=0\\\\\text{And then, for x = 1}\\\\f(1)+f'(1)+2f'(1)=0\\\\ f(1)+3f'(1)=0\\\\ 3f'(1)=-f(1)=-1\\\\\large \boxed{ f'(1)=-\dfrac{1}{3} }$

Thank you

Solve for x. 4x + 5 = 20<br> a X = 5/4<br> b X = 15/4<br> c X = 3.5<br> d X = 15/3

Nonamiya [84]

Step-by-step explanation:

4x+5= 20
4x=20-5
4x= 15
x= 15/4

Need help ASAP thank you

Answer:

x = 14

Step-by-step explanation:

First put it into slope intercept form

20 = 2x - 8

Move the variable to the left hand side and change its symbol

-2x + 20 = -8

Move the constant to the right hand side and change its symbol

-2x = -8 - 20

Calculate the difference

-2x = -28

Divide both sides of the equation by -2

x = 14

Solution

X = 14

So i have a pic i need 1a plz i am giving a bunch of my points plz give it real asap

Answer:

3x - (15 x 3) = 90

3x - 45 = 90

Explanation:

there are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45

Therefore the first part is 3x - 45

We also know that in the end we have 90 left.

So our final equation is:

3x - 45 = 90
