Answer:

[tex]f^{-1}(x) = log_2(x-6)[/tex]

Step-by-step explanation:

To find the inverse [tex]f^{-1}(x)[/tex] of a function follow the following steps.

1) Do y = f (x)

[tex]f(x) =y= 2 ^ x + 6[/tex]

[tex]y= 2 ^ x + 6[/tex]

2) Solve the equation for the variable x.

[tex]y= 2 ^ x + 6\\\\y-6 = 2^x\\\\log_2(y-6) = x\\\\x=log_2(y-6)[/tex]

3) exchange the variable y with the variable x

[tex]x=log_2(y-6)\\\\y=log_2(x-6)[/tex]

Finally the inverse is:

[tex]f^{-1}(x) = log_2(x-6)[/tex]

Answer:

AB=14 cm

Step-by-step explanation:

step 1

Find the measure of major arc AC

we know that

The inscribed angle is half that of the arc it comprises.

so

m∠B=(1/2)[major arc AC]

we have

m∠B=120°

substitute

120°=(1/2)[major arc AC]

240°=major arc AC

so

major arc AC=240°

step 2

Find the measure of arc ABC

we know that

arc AC+arc ABC=360°

substitute

240°+arc ABC=360°

arc ABC=120°

step 3

Find the measure of angle AOC  

m∠AOC=arc ABC=120° ------> by central angle

so

The triangle AOC is an isosceles triangle

OA=OC=14 cm ------> is the radius

The internal angles of triangle AOC are

m∠CAO=m∠OCA=30°

The triangle ABC is an isosceles triangle

AB=BC

The internal angles of triangle ABC are

m∠BAC=m∠ACB=30°

so

Triangles AOC and ABC are congruent by ASA similarity postulate ( two angles and included side)

therefore

AO=AB=14 cm

Answer:

6(N + 12) = 40

Step-by-step explanation:

Number = N

Sum of a number and twelve:

N + 12

Six times the sum of a number and twelve:

6(N + 12)

Six times the sum of a number and twelve is forty:

6(N + 12) = 40

Answer:

6(N+12) = 40

Step-by-step explanation:

The statement says six times the sum . . .

From this we can tell that the answer will be 6 times two numbers added together. Those two numbers are "a number" (some variable) and 12.

We can tell that the variable is N, so it answer must be 6(N + 12) = 40

Answer:

smallest value of x = -1

Largest value of x = 7

Step-by-step explanation:

[tex]x^2-6x=7[/tex]

coefficient of x = -6

Half of the coefficient of x = -6/2 = -3

Square of the half value [tex]=(-3)^2=9[/tex]

Add the square value on both sides of equation

[tex]x^2-6x+9=7+9[/tex]

[tex](x-3)^2=16[/tex]

Take square root

[tex]x-3= \pm \sqrt{16}[/tex]

[tex]x-3= \pm 4[/tex]

[tex]x-3=+4[/tex] or [tex]x-3=-4[/tex]

[tex]x=+4+3[/tex] or [tex]x=-4+3[/tex]

[tex]x=7[/tex] or [tex]x=-1[/tex]

Hence smallest value of x = -1

Largest value of x = 7

Answer:

y=2x

Step-by-step explanation:

If the line is parallel to 4x-2y=6, it means that it has the same slope. So let's first find the slope.

Rearranging, we get

-2y=-4x+6

2y=4x-6

y=2x-3.

So, the slope is 2.

Next, we can use the point slope formula

y-y_1=m(x-x_1)

Substituting, we get

y-2=2(x-1)

y-2=2x-2

y=2x

Answer:

the answer is C: 1932 sq. cm

Step-by-step explanation:

You want to break down the sections (which is double for each)

there are 6 rectangles but you will only need to calculate for 3

1st rectangle

a = (25) (12)

a = 300 sq. cm

**then multiply by 2 = 600 sq. cm**

2nd rectangle

a = (12) (18)

a = 216 sq. cm

then 216 * 2 = 432 sq. cm

3rd rectangle

a = (25) (18)

a = 450 sq. cm

then 450 * 2 = 900 sq. cm

Total Surface Area

SA = 600 sq. cm + 432 sq. cm + 900 sq. cm

SA = 1932 sq. cm

Answer:

XY = 74

Step-by-step explanation:

Using the information given, plug it into the perimeter formula [P=2(l)+2(w)]

90 = 2 (5y - 1) + 2 (4y + 1)

Distribute

90 = 10y - 2 + 8y + 2

Combine like-terms

90 = 18y

Isolate the variable

y = 15

Then, plug it into XY

5 (15) - 1

Multiply

75 - 1

Combine

74

Answer:

XY = 24

Step-by-step explanation:

The perimeter of the rectangle is

2(5y - 1) + 2(4y + 1) = 90 ← distribute parenthesis on left side

10y - 2 + 8y + 2 = 90

18y = 90 ( divide both sides by 18 )

y = 5

XY = 5y - 1 = (5 × 5) - 1 = 25 - 1 = 24

Hi there,

9. Which of the following is the value of x in the solution to the

system of equations given below?

8 + 2x = 5y  (1)

4x - y = 2  (2)

▪ (1)

y = ( 8 + 2x ) ÷ 5

▪ (2)

4x - [( 8 + 2x ) ÷ 5] = 2

( 20x - 8 - 2x ) ÷ 5 = 2

20x - 8 - 2x = 2 × 5

20x - 2x = ( 2 × 5 ) + 8

18x = 10 + 8

18x = 18

x = 18 ÷ 18

x = 1

The answer is : A. 1

•It was nice to help you, SkullNoggin!

Answer:

The graph of function f of x equals log base 3 of x.

Step-by-step explanation:

We have the following equation:

3^y = 8

Taking logarithm(Logarithm with base equal 3) in both sides, we have:

lg_3 (3^y) = lg_3 (8)

ylg_3 (3) = lg_3 (8)

y = lg_3 (8)

So, you can approximate the value of y using the function f(x) = base 3 log (x). Just look for the value of that function for x = 8.

Simplify 1/4c to c/4

c/4 + 2/3 = 1/3

Subtract 2/3 from both sides

c/4 = 1/3 - 2/3

Simplify 1/3 - 2/3 to -1/3

c/4 = -1/3

Multiply both sides by 4

c = -1/3 × 4

Simplify 1/3 × 4 to 4/3

c = -4/3

Final answer:

The angle between the longest side and the diagonal of a 577mm by 1000mm rectangle can be found by first calculating the diagonal using the Pythagorean theorem and then using the arccosine function to find the angle with the longest side.

Explanation:

To calculate the angle between the longest side of a 577mm by 1000mm rectangle and the diagonal, we first need to determine the length of the diagonal using the Pythagorean theorem. The diagonal (d) can be found using the formula d = [tex]\sqrt{(width^2 + height^2)}[/tex]. After calculating the diagonal, we can find the angle using trigonometric ratios, specifically the arccosine function or cos-1.

Step 1: Calculate the diagonal
d = [tex]\sqrt{(577mm^2 + 1000mm^2) }[/tex]=  [tex]\sqrt{(333929 + 1000000) }[/tex] = [tex]\sqrt{1333929}[/tex] ≈ 1155mm

Step 2: Calculate the angle
The angle (θ) between the longest side (adjacent side) and the diagonal (hypotenuse) is given by:
θ = cos-1(adjacent side / hypotenuse) = cos-1(1000mm / 1155mm)

To find the angle, use a calculator to compute the arccosine of 1000/1155.

Answer:

3x(x^2-4x+9)

Step-by-step explanation:

The polynomial 3x^3 - 12x^2 + 27x is factored by first taking out the greatest common factor of 3x, resulting in the final form of 3x(x^2 - 4x + 9), which cannot be factored further over the real numbers due to a negative discriminant.

To factor the polynomial 3x^3 - 12x^2 + 27x, we look for common factors in each term.

We can see that each term of the polynomial has a factor of 3x. So, we factor out 3x from the polynomial:

3x(x^2 - 4x + 9)

Now, we try to factor the quadratic expression x^2 - 4x + 9. However, this quadratic does not have real roots since the discriminant (b^2 - 4ac) is negative (-4^2 - 4 ×1 ×9 = -20). Therefore, it cannot be factored over the real numbers. Our final factored form of the polynomial is 3x(x^2 - 4x + 9), as we factored out the greatest common factor (GCF).

2/n=2/3 ok to start you cross multiply so you would end up with 2*3=2n then you simplify and you get 6=2n now you divide both sides by 2 and end up with 3 so you answer is C. n=3

Answer:

The correct answer option is C. n = 3.

Step-by-step explanation:

We are given the following expression and we are to solve for [tex] n [/tex]:

[tex] \frac { 2 } { n } = \frac { 2 } { 3 } [/tex]

To solve this, we will use the method called cross multiplication where the numerator of left side is multiplied with the denominator of right side and vice versa.

[tex]3 \times 2 = 2 \times n[/tex]

[tex]2n = 6[/tex]

[tex]n=\frac{6}{2}[/tex]

[tex]n=3[/tex]

Therefore, the correct answer option is C. n = 3.
