Answer:

A. 8 cm sq

Step-by-step explanation:

Find the scale factor

new width/original width

8/1.6=5

calculate length of original rectangle

new length/scale factor

25/5=5cm

Find area of original rectangle

A=l×w

A=1.6×5=8cm²

A is the answer

You find the scale factor by doing 8÷1.6 which = 5

Then you do 25÷5=5

And then times 5 and 1.6 together to get 8cm sq

Answer:

¹²/₇

Step-by-step explanation:

Model ⁴/₇ × 3

Assume that you have three pies, each dived into seven slices.

There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate

The picture represents ⁴/₇ × 3.  

Model the product

Now, transfer slices to get as many filled pie plates as possible.

Count the total slices.

You have 12 slices, and each slice represents ⅐ of a pie.

You have ¹²/₇  pie.

∴ ⁴/₇ × 3 = ¹²/₇

Answer:

Step-by-step explanation:

[tex]g(x) =\frac{1}{2} f(x+3)+\frac{1}{2}[/tex]

Following changes are made in f(x) i.e. Line m to get g(x) i.e. the Line m'

1) Multiplication of f(x) by 1/2

Multiplying the function by a number indicates dilation. So this means Line m is dilated by a factor of 2. The dilation in this case is compression. So the function is being compressed by a factor of 2.

2) Addition of 3 to x

Addition of a value directly to x shifts it horizontally towards left. So Line m is shifted 3 units to left.

3) Addition of 1/2 to function value

Addition of a number to function value indicates vertical upward shift. So the Line m is shifted up by 1/2 units

Step-by-step explanation:

A rational number is a number that can be expressed as a fraction of two whole numbers, like 3/1 (3), 8/10 (0.8), or even something crazy like 23784/924433 (0.0257...). ... For example, pi and the square root of two cannot be expressed as a fraction of two whole numbers, so they are both irrational.

No 23/3 is a rational number.

Irrational numbers are real numbers that cannot be represented as simple fractions. An irrational number cannot be expressed as a ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.

Given here the number N=23/3 which is of the form p/q where p,q are integers, thus N is a rational number.

Hence, N is not a irrational number.

Answer:

see explanation

Step-by-step explanation:

given

[tex]\frac{x8x^2-8}{4x+4}[/tex] , x ≠ - 1

The x ≠ - 1 means that x cannot take the value of - 1 as this would make the denominator equal to zero which would make the fraction undefined.

Factor the numerator/ denominator

8x² - 8 = 8(x² - 1) ← factor out 8 from both terms

x² - 1 ← is a difference of squares, hence

8x² - 8 = 8(x - 1)(x + 1)

4x + 4 = 4(x + 1) ← factor out 4 from both terms

Thus the fraction now simplifies to

[tex]\frac{8(x-1)(x+1)}{4(x+1)}[/tex]

Cancel the 8 and 4 by 4 and cancel the factor (x + 1), leaving

=  2(x - 1) = 2x - 2 ← in the form ax + b

Answer:

The solutions are (-2 , 0) and (1 , 3)

Step-by-step explanation:

∵ -x² + 4 = x + 2

* y = -x² + 4 ⇒ is quadratic represented by parabola

 The parabola open downward because coefficient of x² is negative

 The x-coordinate of its vertex = -b/2a, where b is the

  coefficient of x and a is the coefficient of x²

∴ x = 0/2(-1) = 0

∴ The y-coordinate of the vertex = (0)² + 4 = 4

∴ The maximum point of the parabola is (0 , 4)

∵ -x² + 4 intersects x-axis at y = 0

∴ -x² + 4 = 0 ⇒ -x² = -4 ⇒ x² = 4

∵ x² = 4

∴ x = ±√4 = ± 2

∴ the parabola intersects x-axis at -2 , 2

∵ y = x + 2 represented by a line its slope = 1

  It intersects y-axis at 2

∵ x + 2 intersects x-axis at y = 0

∴ x + 2 = 0

∴ x = -2

∴ The parabola and the line intersect each other at

  x = -2 and y = 0

To find all the point of intersection between the 2 equations we will solve them as a system of equations

∵ y= -x² + 4  and y = x + 2

∴ -x² + 4 = x + 2

∴ -x² + 4 - x - 2 = 0

∴ -x² - x + 2 = 0 ⇒ × -1

∴ x² + x - 2 = 0 ⇒ factorize

∴ (x + 2)(x - 1) = 0

∴ x + 2 = 0 ⇒ x = -2

∴ x - 1 = 0 ⇒ x = 1

* when x = -2 ⇒ y = -2 + 2 = 0 ⇒ (-2 , 0)

* when x = 1 ⇒ y = 1 + 2 = 3 ⇒ (1 , 3)

Answer:

x > 80,000

Step-by-step explanation:

3600+1.02x<2000+1.04x

The first thing we need to do is to isolate the x's and get all of them on one side, let's start off by subtracting 2,000 from both sides of the equation.

1,600+1.02x<1.04x

Now, subtract 1.02x from both sides to get both the x's on one side.

1600<0.02x

Divide by 0.02 to solve for x.

80,000<x

We can flip the sign and swap the places of the number and variable so that x is on the left side.

x > 80,000

To solve the inequality 3600+1.02x<2000+1.04x algebraically, follow the steps: Move terms, combine like terms, simplify, and isolate x.

To solve the inequality 3600+1.02x<2000+1.04x algebraically, we can follow these steps:

I can give you an answer, but I don't know how you would find it on your own. The smallest number I found was 301

You can see that 2 and 5 do leave a remainder of 1.

You can also see the 301 / 3 leaves a remainder of 1

What about 4? 301 / 4 = 75 with a remainder of 1.

301 / 6 = 50 with a remainder of 1.

301/7 = 43 with no remainder.

What a strange question.

All of these from 2 to 6 divide into 300 evenly. 301 gives a remainder of 1.

But 301 = 7 * 43

Nine

Let the smaller to the 2 angles = x

Therefore the larger one is 3x + 2

The third angle = 90 degrees.

3x + 2 + x + 90 = 180                    Combine like terms on the left.

4x + 92 = 180                                Subtract 92 from both sides.

4x = 180 - 92

4x = 88                                          Divide by 4

x = 88/4

x = 22

So the three angles are

66 + 2 = 68

Consider the least common multiple of 6 and 8

The multiples of 6 are : 6, 12, 18, 24, 30, 36, ......

The multiples of 8 are : 8, 16, 24, 32, 40, ......

The common multiple is 24 or 48 or 72

The multiples of 18 are : 18, 36, 54, 72, 90, ....

Since 72 is a common multiple of 8 and 6 and also a multiple of 72

Then the least common multiple of 6, 18 and 8 is 72

the solid is made up of 2 regular octagons, 8 sides, joined up by 8 rectangles, one on each side towards the other octagonal face.

from the figure, we can see that the apothem is 5 for the octagons, and since each side is 3 cm long, the perimeter of one octagon is 3*8 = 24.

Answer:

B

Step-by-step explanation:

(f - g)(x) = f(x) - g(x) and

f(x) - g(x) = 4x² + 1 - (x² - 5) = 4x² + 1 - x² + 5 = 3x² + 6 → B

To find (f-g)(x), we simply subtract g(x) from f(x) and combine like terms. The resulting function is (f-g)(x) = 3x^2 + 6, therefore the correct answer is B. 3x^2 + 6.

To find (f-g)(x), we subtract the function g(x) from f(x). Given f(x) = 4x^2 + 1 and g(x) = x^2 - 5, we perform the subtraction:

f(x) - g(x) = (4x^2 + 1) - (x^2 - 5)

First, distribute the negative sign through the g(x) function:

f(x) - g(x) = 4x^2 + 1 - x^2 + 5

Now, combine like terms:

f(x) - g(x) = 4x^2 - x^2 + 1 + 5

f(x) - g(x) = 3x^2 + 6

So the correct answer is B. 3x^2 + 6.
