If a =5, 0, −1,find a vector b such that compab = 2.b = _______.

Answers

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]

Vector:

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]

Write 0.0000002711 in scientific notation. (Use 2 numbers after the decimal point.)

Answers

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 expanded form for 300684 can be written with only 4 add ends. Explain how this is possible for a number with 6 digits

Answers

Answer:

This can be because our number, 300,684, has only four digits different than zero.

Then we can write this number as:

300,684 = 300,000 + 600 + 80 + 4.

So we add only 4 terms.

So when we write a number in this form, we will have the same numbers of terms in the addition that the number of digits different than zero in our original number.

Josh has 212 marbles. Peck has 314 marbles. Round each number to the nearest hundred. Then, type how much marbles more does Peck have.

Answers

Round each number to the nearest hundred.

 212 = 200.

 314 = 300.

How much more marbles does Peck have?

 314 - 212 = 102.

That is your answer. Hope this helps!

Answer:

100 more marbles

Step-by-step explanation:

So first let's round the numbers to the nearest hundred. So 212 rounds to 200, and 314 rounds to 300. Then we do 300-200 and get 100. SO the answer is 100.

Problem 4: Give an example of a system of linear equations that has no solutions. Explain how can you decide the number of solutions without solving the system.

Answers

Answer:

x=2 and y=1

Step-by-step explanation:

2x+y=5

x-y=1

buy adding both equations we get

3x=6

x=2  ( divide 3 on both sides)

put x=2 in any equation  

2-y=1

y=2-1

y =1

p2

Problem#2

Let say two complementary angles are A & B

difference of two complementary angles is 30°

=> A - B = 30

Sum of  two complementary angles is 90°

=> A + B = 90

Hence A = 60° , B = 30°

Problem#3

Total bill  = 30

$ 10 Bills = A

$ 20 Bills  = B

10 * A  + 20* B = 460

A + B = 30

A = 14 , B = 16

Problem#4

4x+2=y

2y−8x=10

The first step is to simplify the second equation into

Now, the two equations are:

y=4x+2

Bepotastine besilate (BEPREVE) ophthalmic solution contains 1.5% w/v of the therapeutic agent. Express this concentration in mg/mL.

Answers

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

Answers

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]

Factor this trinomial 4x^2-6x-10 If you can please try to show me how to do it.

Answers

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!

find simple interest on #1200 for 3 years at 4.25% per anum​

Answers

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
