Answer:

The unit vector in component form is [tex]\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)[/tex] or [tex]\hat{u} = \frac{2}{\sqrt{13}}\,i-\frac{3}{13}\,j[/tex].

Step-by-step explanation:

Let be [tex]\vec u = (2,-3)[/tex], its unit vector is determined by following expression:

[tex]\hat {u} = \frac{\vec u}{\|\vec u \|}[/tex]

Where [tex]\|\vec u \|[/tex] is the norm of [tex]\vec u[/tex], which is found by Pythagorean Theorem:

[tex]\|\vec u\|=\sqrt{2^{2}+(-3)^{2}}[/tex]

[tex]\|\vec u\| = \sqrt{13}[/tex]

Then, the unit vector is:

[tex]\hat{u} = \frac{1}{\sqrt{13}} \cdot (2,-3)[/tex]

[tex]\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)[/tex]

The unit vector in component form is [tex]\hat{u} = \left(\frac{2}{\sqrt{13} },-\frac{3}{\sqrt{13}} \right)[/tex] or [tex]\hat{u} = \frac{2}{\sqrt{13}}\,i-\frac{3}{13}\,j[/tex].

Step-by-step explanation:

Hey, there!!

[tex] = \frac{43}{7} [/tex]

Divide 43 by 7.

you will get quotient as 6 and remainder is 1.

so,

The proper fraction is:

[tex] = 6 \frac{1}{7} [/tex]

Hope it helps...

First must do the division:

43 : 7 = 6 with 1 of rest

so 43 = 6 * 7 + 1

with the denominator:

[tex]\frac{43}{7} = \frac{6*7+1 }{7}[/tex]

[tex]\frac{43}{7} = \frac{6*7 }{7}+\frac{1}{7}[/tex]

semplify:

[tex]\frac{43}{7} = 6+\frac{1 }{7}[/tex]

Answer:

1st Slot: f(-3)

2nd Slot: -3

3rd Slot: is not

Step-by-step explanation:

Using the Remainder Theorem, we plug in the root of x + 3 (which is x = -3) and see the remainder.

If the remainder = 0, it is a factor

If the remainder ≠ 0, it is NOT a factor

f(-3) = -2(-3)⁴ - 8(-3)³ - 2(-3) - 63

f(-3) = -3

So, x + 3 is NOT a factor.

We then have our 3 answers.

Answer:

The width of the poster will be 17 inches

Step-by-step explanation:

The area = 204  square inches

Note:

- both length and width are whole numbers

- The width of the poster is greater than 11 inches

- The width is a prime

The prime numbers greater than 11 are

13, 17, 19, 23, 29, ...,

all these numbers divide 204 with a remainder except for 17

Therefore, the width will be 17 inches, and the length will be 12

since 17 divides 204 into 12 places

B. (3, -7)

When the equation is graphed, the vertex is at the point (3,-7). I hope this helps!!!

The vertex of the quadratic expression g(x) = 8x² - 48x + 65 is (3, -7).

Quadratic expressions are polynomial expressions of second degree.

The general form of a quadratic expression is ax² + b x + c.

The vertex of a quadratic function f(x) = ax² + b x + c is,

(-b/2a, f(-b/2a)).

Here the function is,

g(x) = 8x² - 48x + 65

b = -48 and a = 8.

Vertex = (-(-48) / 16, g(-(-48) / 16))

           = (3, g(3))

g(3) = 8(3)² - 48(3) + 65 = 0

g(3) = -7

Hence the correct option is B.

Option (B)

Step-by-step explanation:

Average waiting time in the month of October = 20 minutes

Average waiting time in the month of November = 30 minutes

Average waiting time in the month of December = 60 minutes

Average waiting time in the month of January = 40 minutes

Average waiting time in the month of February = 10 minutes

Average waiting time in the month of March = 10 minutes

Average waiting time in the month of April = 30 minutes

Average waiting time in the month of May = 40 minutes

Average waiting time in the month of June = 20 minutes

Total waiting period from October to June = 20 + 30 + 60 + 40 + 10 + 10 + 30 + 40 + 20 = 260

Average waiting period = [tex]\frac{260}{9}[/tex]

Answer:

[tex]q(x)=2x-5,x\neq-2[/tex]

Step-by-step explanation:

So we have:

[tex]a(x)=2x^2-x-10\\b(x)=x+2[/tex]

And we want to find the quotient q(x). Thus:

[tex]q(x)=\frac{a(x)}{b(x)}[/tex]

Substitute:

[tex]q(x)=\frac{2x^2-x-10}{x+2}[/tex]

Factor the numerator:

[tex]2x^2-x-10\\=2x^2+4x-5x-10\\=2x(x+2)-5(x+2)\\=(2x-5)(x+2)[/tex]

Substitute:

[tex]q(x)=\frac{(2x-5)(x+2)}{x+2}[/tex]

The (x+2)s cancel out. Therefore:

[tex]q(x)=2x-5[/tex]

However, we must restrict x such that it cannot equal -2.

In the original equation, if it did, our answer would be undefined. Thus, our final answer is:

[tex]q(x)=2x-5,x\neq-2[/tex]

And we are done :)

Answer:

45.0

Step-by-step explanation:

44.981 = 45.0 (to 3 s.f.)

*important point to note: the 0 must be included as the question asked for 3 significant figures. In this case, 0 is significant.

I hope this helps :)

Rounding 44.981 to three significant figures gives us 44.9.

To round the value 44.981 to three significant figures, we start counting from the leftmost non-zero digit.

The three significant figures in this case are "44.9".

The digit immediately after the third significant figure is 8.

Since 8 is greater than or equal to 5, we round up the last significant figure, which is 9.

Therefore, rounding 44.981 to three significant figures gives us 44.9.

Answer:

Since the height is twice the base, we can substitute the value [tex]2b[/tex] in as [tex]h[/tex] in the expression, making it [tex]\frac{b\cdot2b}{2}[/tex]. If the area is 16, we can make the equation

Answer:

[tex]f(x) = 1588.4x + 39000[/tex]

[tex]f(15) = 62826[/tex]

Step-by-step explanation:

Given

In 1990; Income= $39000

In 2010; Income= $70768

Solving (a): An equation in form of f(x) = ax + b

First, we need to determine the slope, a

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Taking y as income and x as year index.

When x = 0; y = 39000

When x = 20; y = 70768

Substitute these values in the above formula

[tex]a = \frac{70768 - 39000}{20 - 0}[/tex]

[tex]a = \frac{31768}{20}[/tex]

[tex]a = 1588.4[/tex]

Next, is to determine the formula using:

[tex]y - y_1 = a(x - x_1)[/tex]

Considering :When x = 0; y = 39000, we have

[tex]y - 39000 = 1588.4(x - 0)[/tex]

[tex]y - 39000 = 1588.4x[/tex]

Make y the subject of formula

[tex]y = 1588.4x + 39000[/tex]

Express y as a function of x

[tex]f(x) = 1588.4x + 39000[/tex]

Solving (b): Income in 2005

In 2005, x = 15

So:

[tex]f(x) = 1588.4x + 39000[/tex] becomes

[tex]f(15) = 1588.4 * 15 + 39000[/tex]

[tex]f(15) = 62826[/tex]

so the answer is 1 and 9

Step-by-step explanatio:

The values of x can be 1 or 9.

The correct option is (B) and (C).

A statement of equality between two expressions consisting of variables and/or numbers. In essence, equations are questions, and the development of a mathematics has been driven by attempts to find answers to those questions in a systematic way.

For example

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc.

Given:

x= 5 ± √16

Now, taking the root of 16 which is +4 and -4.

So, x= 5 ± 4

We have two values ,

x= 5+4 or x= 5-4

x=9 or 1

Hence, the solution to x= 5 ± √16 is B. 1 and C. 9.
