Answer:

[tex]Number = 2.71 * 10^{-7}[/tex]

Step-by-step explanation:

Given

[tex]Number = 0.0000002711[/tex]

Required

Write, using scientific notation

The scientific notation is written in the form:

[tex]Form = a * 10^n[/tex]  Where n is an integer and [tex]1 \leq a \leq 10[/tex]

To start with; Represent the given number as fraction

[tex]Number = \frac{2711}{10000000000}[/tex]

Represent the denominator as an exponent

[tex]Number = \frac{2711}{10^{10}}[/tex]

This can be rewritten in form of:

[tex]Number = 2711 * 10^{-10}[/tex]

Remember that: [tex]Form = a * 10^n[/tex]  Where n is an integer and [tex]1 \leq a \leq 10[/tex]

This implies that; we need to adjust 2711 to a number between 1 and 10;

This gives:

[tex]Number = 2.711 * 1000 * 10^{-10}[/tex]

Write 1000 as an exponent

[tex]Number = 2.711 * 10^3 * 10^{-10}[/tex]

Apply law of indices

[tex]Number = 2.711 * 10^{3-10}[/tex]

[tex]Number = 2.711 * 10^{-7}[/tex]

The question requires 2 numbers after the decimal point;

So, 2.711 will be approximated to 2.71

[tex]Number = 2.71 * 10^{-7}[/tex]

Hence;

[tex]0.0000002711[/tex]  is equivalent to [tex]2.71 * 10^{-7}[/tex]

The slope is undefined.

The graph will be a vertical line.

Step-by-step explanation:

just did it

The graph will be a vertical line. Option C is correct.

Given that,
The slope of the line is zero we have to determine what are the conditions.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The slope of the line is zero,
m = 0
tanФ = 0
y / x = 0
for the above condition, Δy must be zero or Δx must be infinite and the line will be a verticle.

Thus, the graph will be a vertical line. Option C is correct.

Answer:

radius = 1.37 cm

height = 2.71 cm

Step-by-step explanation:

We are given volume = 16 m³.

Formula for volume of a cylinder is;

V = πr²h

Thus,

πr²h = 16

h = 16/πr²

Now formula for the surface area is;

S = 2πr² + 2πrh

Putting 16/πr² for h gives;

S = 2πr² + 2πr(16/πr²)

S = 2πr² + 2π(16/πr)

S = 2π(r² + 16/πr)

To minimize, we will find the derivative of S and equate to zero

S' = 2π(2r - 16/πr²) = 0

4πr - 32/r² = 0

4πr = 32/r²

r³ = 32/4π

r = ∛(32/4π)

r = 1.37 cm

From h = 16/πr²;

h = 16/(π × 1.37²)

h = 2.71 cm

Answer:

[tex]f(-1) = \frac{5}{2}[/tex]

[tex]f(0) = 5[/tex]

[tex]f(2) = 20[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 5(2^x)[/tex]

Required

Determine f(-1); f(0) and f(2)

Solving f(-1)

In this case, we simply take x as;

[tex]x = -1[/tex]

Substitute -1 for x in [tex]f(x) = 5(2^x)[/tex]

[tex]f(-1) = 5(2^{-1})[/tex]

Apply law of indices

[tex]f(-1) = 5 * \frac{1}{2}[/tex]

[tex]f(-1) = \frac{5}{2}[/tex]

Solving f(0)

In this case, we simply take x as;

[tex]x = 0[/tex]

Substitute 0 for x in [tex]f(x) = 5(2^x)[/tex]

[tex]f(0) = 5(2^0)[/tex]

[tex]f(0) = 5(1)[/tex]

[tex]f(0) = 5[/tex]

Solving f(2)

In this case, we simply take x as;

[tex]x = 2[/tex]

Substitute 2 for x in [tex]f(x) = 5(2^x)[/tex]

[tex]f(2) = 5(2^2)[/tex]

[tex]f(2) = 5(4)[/tex]

[tex]f(2) = 20[/tex]

Answer:

[tex]b  =  (q,r , 5q-2\sqrt{26} )[/tex]

Step-by-step explanation:

From the question we are told that

The vector given is  

               [tex]a = (5,0,-1)[/tex]

  Also  [tex]comp_a b =  2[/tex]

Generally

       [tex]comp_a b  =  \frac{a \cdot b}{|a|}[/tex]

Here  [tex]|a|[/tex] is the magnitude of  a which is mathematically represented as

      [tex]|a| =  \sqrt{5^2  + 0^2  +(-1)^2 }[/tex]

=>     [tex]|a| =  \sqrt{26}[/tex]

b is vector which we will assume to have the following parameters

     [tex]b  =  (q , r , x)[/tex]

So

        [tex]comp_a b =  \frac{(5,0,-1) \cdot (q,r,x)}{\sqrt{26} } =  2[/tex]

=>     [tex]\frac{5q + 0 -x}{\sqrt{26} } = 2[/tex]

=>     [tex]x =  5q-2\sqrt{26}[/tex]

Hence the vector be can be mathematically represented as

      [tex]b  =  (q,r , 5q-2\sqrt{26} )[/tex]

This means that the vector b is more than one value  since it is made up of variable

This means that if

   [tex]q = 1\\r=1\\x =1[/tex]

Then

    [tex]b  =  (1,1,5-2\sqrt{26} )[/tex]

A quantity has magnitude but not position, that's why in this the vector [tex]b =(0,0, -2\sqrt{26}).[/tex]

If[tex]a =(5,0,-1)[/tex] Our goal is to determine a vector b that will allow comp to work properly [tex]_{a}b = 2.[/tex]

Allow the vector to flow naturally  [tex]b =(x, y,z)[/tex]

Recalling

comp[tex]_{a}b =\frac{a.b}{|a|}[/tex]

Therefore,

comp [tex]_{a}b= 2 \\\\[/tex]

[tex]\to \frac{a.b}{|a|}= 2\\\\[/tex]

[tex]\to \frac{(5,0,-1)\cdot (x,y,z)}{ |(5,0,-1)|} =2\\\\\to \frac{5x+0-z}{5^2+0+(-1)^2}=2\\\\ \to \frac{5x-z}{\sqrt{26}}= 2 \\\\\to 5x-z = 2\sqrt{26}\\\\ \to z=5x-2\sqrt{26}\\\\[/tex]

As a result, the vector b can be expressed as,

[tex]\to b =(x,y,z) =(x, y, 5x-2\sqrt{26}) \\\\[/tex]

As a result, this aforementioned form can be found in an endless number of vectors.

One of them is [tex]b =(0,0, -2\sqrt{26}).[/tex]

Answer:

$153.00

Step-by-step explanation:

A = $1,353.00

(I = A - P = $153.00)

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year.

Solving our equation:

A = 1200(1 + (0.0425 × 3)) = 1353

A = $1,353.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,200.00 at a rate of 4.25% per year for 3 years is $1,353.00.

Answer:

$153

Step-by-step explanation:

Simple Intrest = P ( money invested ) * R ( percentage ) * T ( year )

I = P * R * T / 100

I = 1200 * 4.25 * 3 = 15300 / 100 = $153

Given that:

r = sin 2θ  , θ = ± π/4 , ± 3π/4

Recall that:

x = r cosθ

y = r sinθ

The  differential of y with respect to x

[tex]\dfrac{dy}{dx} = \dfrac{\dfrac{dy}{d \theta}}{\dfrac{dx}{d \theta}}[/tex]

[tex]\dfrac{dy}{dx} =\dfrac{\dfrac{dy}{d \theta}}{\dfrac{dx}{d \theta}} = \dfrac{ r cos \theta + sin \theta* \dfrac{dr}{d \theta} } {\dfrac{dr}{d \theta} *cos \theta- sin \theta \ r}[/tex]

at  θ = π/4  , r = sin π/2

r = 1

where;

θ = π/4

[tex]\dfrac{dy}{dx} = \dfrac{ 1 \times cos (\dfrac{\pi}{4}) + 2 cos (\dfrac{\pi}{2})*sin (\dfrac{\pi}{4}) } {2 \ cos (\dfrac{\pi}{2})*cos (\dfrac{\pi}{4})- sin (\dfrac{\pi}{2}) * sin (\dfrac{\pi}{4})}[/tex]

Answer:

15mg/ml

Step-by-step explanation:

Percent mass per volume ( % m/v) is unit expression that tells us how many grams of a solute that we can find 100 ml of a particular solution.

In the above question, we are asked to express 1.5%w/v Bepotastine besilate (BEPREVE) ophthalmic solution as mg/mL

Step 1

1.5% w/v = 1.5 g of Bepotastine besilate (BEPREVE) in 100ml ophthalmic solution

Hence, if

100ml = 1.5g

1 ml = y g

We Cross Multiply

100ml × yg = 1 ml × 1.5g

yg = 1 ml × 1.5g/100ml

= 0.015g

Therefore, in 1 ml we have 0.15 g.

Step 2

Since we are asked to express as mg/ml

We convert 0.015g to mg

1 gram = 1000 milligrams

0.015 grams =

Cross Multiply

0.015grams × 1000 milligrams/ 1 gram

= 15 mg

Therefore, the concentration in mg/ml of 15% m/v of Bepotastine besilate (BEPREVE) ophthalmic solution is 15mg/ml

Answer:

[tex]=2(2x-5)(x+1)[/tex]

Step-by-step explanation:

So we have the trinomial:

[tex]4x^2-6x-10[/tex]

First, factor out a 2:

[tex]=2(2x^2-3x-5)[/tex]

Now, factor within the parentheses.

To do so, we want to find two numbers. When multiplied, these two numbers must equal (a)(c) and when added, they must equal b

(a)(c) is 2(-5) or -10 and b is -3. So, we want two numbers that when multiplied together gives -10 and when added gives -3.

-5 and 2 works. Therefore:

[tex]=2(2x^2-3x-5)[/tex]

Replace -3x with 2x and -5x:

[tex]=2(2x^2+2x-5x-5)[/tex]

Factor out a 2x for the first two terms. And factor out a negative 5 for the remaining two:

[tex]=2(2x(x+1)-5(x+1))[/tex]

Grouping:

[tex]=2(2x-5)(x+1)[/tex]

And we're done!
