Which of the following best describes the relationship between ABCD EFGH?

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

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:

[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:

The opposite of the number 1/4 is equal to -1/4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the number is 1/4 and the opposite of the number will be calculated as,

The opposite will be the negative value of 1/4.

Positive value = 1/4

Negative value = -1/4

Therefore, the opposite of the number 1/4 is equal to -1/4.

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].

Answer:

7.5%

Step-by-step explanation:

Approximate distance = 180 miles

Actual distance = 167.5 miles

Percent error = { (approximate value - actual value) / actual value } × 100

= { (180 - 167.5) / 167.5 } × 100

= (12.5 / 167.5) × 100

= 0.075 × 100

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]

Answer:

x = 5 +/- 4 ([tex]\sqrt{16}[/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.

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.

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.
