Answer:

The derivative of function [tex]f(x)=5\sqrt{x}[/tex] is [tex]\frac{5}{2\sqrt{x} }[/tex]

Step-by-step explanation:

We need to find derivative of the given function [tex]f(x)=5\sqrt{x}[/tex]

Finding the derivative:

[tex]\frac{d}{dx}(5\sqrt{x} )[/tex]

Using the rule (a.f)' = a(f)', taking out constant value 5

[tex]=5\frac{d}{dx}(\sqrt{x} )[/tex]

We know [tex]\sqrt{x} =x^{\frac{1}{2}[/tex] Replacing [tex]\sqrt{x}[/tex]

[tex]=5\frac{d}{dx}(x^{\frac{1}{2}} )[/tex]

Applying derivative rule: [tex]\frac{d}{dx}(x^a)= a.x^{a-1}[/tex]

[tex]=5\times\frac{1}{2}(x^{\frac{1}{2}-1} )\\=\frac{5}{2}(x^{-\frac{1}{2}} )\\=\frac{5}{2x^{\frac{1}{2}}}\\=\frac{5}{2\sqrt{x} }[/tex]

So, the derivative of function [tex]f(x)=5\sqrt{x}[/tex] is [tex]\frac{5}{2\sqrt{x} }[/tex]

Answer:

90 mirrors

Step-by-step explanation:

If 5 mirrors=30 mins

then x=9 hrs

therefore 30÷60 to covert it to hours is equal to 0.5hr

5×9hrs÷0.5hr=90

therefore x=90

Can i have brainliest?

Answer:

6 times

Step-by-step explanation:

We will have to divide in order to solve this problem.

[tex]\frac{3}{4}[/tex]÷[tex]\frac{1}{8}[/tex]

We will have to find the reciprocal of 1/8, which is basically flipping it, so it is 8.

After, we will have to multiply 3/4x8. The product would come out as 24/4, and if you simplify it, the answer will be 6 times.

The correct option is b

Step-by-step explanation:

From the question we are told that

   The average monthly  rent for one-bedroom apartment in Chattanooga has been  

         [tex]\mu = \$ 1200[/tex]

This mean that the null hypothesis is  

        [tex]H_o : \mu = \$ 1200[/tex]

Generally given from the question that it is believed that there has been a decrease in the average rental , it then mean that the  alternative hypothesis is  

         [tex]H_a : \mu < \$ 1200[/tex]

Answer: $450

Step-by-step explanation:

Given that:

Amount borrowed = $450

Amount charged per lawn = $35

Operating cost per lawn = $8

Jimmy's cost (C(x)) :

Amount borrowed + operating cost

If x lawns are mowed :

$450 + $8 per lawn

$450 + $8x

C(x) = 450 + 8x

Intercept (value of y when x = 0

Value of C(x) ; when x = 0

C(x) = 450 + 8(0)

C(x) = 450 + 0

C(x) = 450

Answer:

[tex]\frac{18}{5}[/tex]

Step-by-step explanation:

Given coordinates;

                     (15,36) and (30,72)

Unknown:

Slope of the line  = ?

Solution:

     (15,36) and (30,72);

  Slope is the rise divided by the run. To find the slope, we use the expression below;

   Slope  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

y₁ = 36

y₂ = 72

x₁ = 15

x₂ = 30

  Insert the parameters and solve;

  Slope  = [tex]\frac{72 - 36 }{30 -15}[/tex]   = [tex]\frac{36 }{15}[/tex]

 Slope  = [tex]\frac{18}{5}[/tex]

Step-by-step explanation:

I divided 40 by 16, then multiplied that by 20, and there's the awnser!

If  Olivia has read 40 pages of a 70-page book. Then 57.196% of pages has Olivia read

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Olivia has read 40 pages of a 70-page book.

We need to find percent of pages has Olivia read

Let x be the percent of books olivia read.

This can be done by 70 x=40

Divide both sides by 70

x=40/70

x=0.5719

Now multiply this with 100

0.5719×100

57.196

Hence 57.196% percent of pages has Olivia read
