Answer:

The answer will be listed below.

Step-by-step explanation:

The scientific notation of 0.0094592 would be 9.4592x10^-3 power. The scientific notation of 0.94592 would be 9.4592x10^-1. To put a standard notation into scientific notation, simply move the decimal left to right until you have a number in the ones place that isn't zero.

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

y = 3x² + 1

Differentiate both sides with respect to t :

dy/dt = 6x dx/dt

We're given that dy/dt = +3 units/second, so when x = 2 we find

3 u/s = 6 • 2 dx/dt

dx/dt = 3/12 u/s = 1/4 u/s

which means x is increasing at a rate of 1/4 units per second.

Answer:

The value is  [tex]P( 1.39 < z < 1.53 ) = 0.0193[/tex]

Step-by-step explanation:

From the question we are told to obtain the area to the of the z-score 1.39 and to the left of the z-score 1.53, this is mathematically represented as

        [tex]P( 1.39 < z < 1.53 ) = P( z < 1.53 ) - P( z < 1.39 )[/tex]

From the z table on the question the area under the normal curve to the left corresponding to 1.53 and  1.39  is

       [tex]P( z < 1.53 ) = 0.9370[/tex]

and

      [tex]P( z < 1.39 ) = 0.9177[/tex]

So

     [tex]P( 1.39 < z < 1.53 ) = 0.9370 - 0.9177[/tex]

=>  [tex]P( 1.39 < z < 1.53 ) = 0.0193[/tex]

Step-by-step explanation:

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: $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]

Answer: You can have about 13 loafs of pumpkin bread.

Step-by-step explanation: 3/4 is the same as 0.75 so you will add 0.75 to 0.75 13 times

0.75+0.75+0.75+0.75+0.75+0.75+0.75+0.75+0.75+0.75+0.75+0.75+0.75=13.33.

13.3 is not a whole number so you will say 13.

Answer:

5304

Step-by-step explanation:

You can use the distributive property to solve for this

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Answer:

-3>-5

Step-by-step explanation:

Answer:

In the image, we can see that the arrows go from the negative pole to the positive pole.

This image then represents the flow of electrons in the situation (Remember that we define current as the flow of "holes", so current is usually defined in the opposite direction than the flow of electrons).

Second question:

In a current, the electrons usually do not move really fast (in average velocity).

Now, the current flowing in a given material will depend mostly on:

The area of the material (a cable with larger diameter can have a larger electricity than a thin cable) and the material itself (there are some materials that are really good conductors, and there are materials that are bad conductors)

Now, this concept of good/bad conductor can be thought as follows,

A bad conductor has a lot of particles (for example electrons in the inner energy levels) in the way of the flow of electrons, and when the electrons want to move, they may interact with those particles, and then the flow of electrons is diminished.

For a good conductor, those particles do not interact, and there are not a lot of these particles. (Also good conductors have more electrons in the valence level, so there are more electrons that can flow in the material).

Another important factor is the temperature of the material, we know that when we increase the temperature of a material, the particles of this material will have an increment in its kinetic energy, then those particles will be moving a lot, and there is a larger possibility that there will be an interaction with the flowing electrons.

In the case where the object is really cold, the kinetic energy of the particles will be small, and these will be more "ordered", which helps with the current flow.

Then we can conclude that the electricity does not really depend on the speed of the electron, it depends more of the material of the conductor and the cross-section area.

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

Answer

It will take him 450 minutes to read 90 pages.

Explanation

Luis can read 3 pages every 15 minutes.

You are trying to find how long it will take him to read 90 pages.

Set up this ratio.

[tex]\frac{15}{3} =\frac{x}{90}[/tex]

To get from 3 to 90, you multiply by 30. Do the same thing to 15.

15 times 30 is 450.
