Answer:

  f^-1(x) = 4+∛((x-6)/5)

Step-by-step explanation:

To find the inverse function, solve ...

  x = f(y)

then write the answer in functional form.

  [tex]\displaystyle x=f(y)\\\\x=5(y-4)^3+6\\\\x-6=5(y-4)^3\\\\\frac{x-6}{5}=(y-4)^3\\\\\sqrt[3]{\frac{x-6}{5}}=y-4\\\\y=4+\sqrt[3]{\frac{x-6}{5}}\\\\\boxed{f^{-1}(x)=4+\sqrt[3]{\frac{x-6}{5}}}[/tex]

We know this because it says the chef uses 2 1/6 boxes on one day and 1 4/6 on the other.

2 + 1 = 3

1/6 + 4/6 = 5/6 (cannot be simplified)

Put them together = 3 and 5/6

4 2/3 + 3 4/5 = 8 7/15

change to a common denominator:

4 10/15 + 3 12/15 = 7 22/15

reduce:

7 22/15 = 8 7/15

When the given mixed fractions are solved and tired to prove that both the sides are equal, the result will show that the given equation is correct.

A proper fraction that is less than one whole must represent the fractional portion of the mixed number. When a fraction is written properly, the top number, or numerator, must be less than the bottom number, or denominator.

A mixed fraction is one that has both a whole number and a fractional component. Additionally known as "Mixed numerals"

4 ⅔  + 3 ⅘  = 8  ⁷/ ₁₅  

¹⁴/ ₃ + ¹⁹ / ₅ = ¹²⁷ / ₁₅

⁷⁰ / ₁₅ + ⁵⁷ / ₁₅ = ¹²⁷ / ₁₅

¹²⁷ / ₁₅ =  ¹²⁷ / ₁₅

The result will demonstrate that the above equation is accurate when the given mixed fractions are solved and used to demonstrate that both sides are equal.

Answer:

100 by 190 in.

Step-by-step explanation:

Ratios are only equal if both numbers are divided by the same number.

10 : 19 = (10 × 10) : (19 × 10)

10 : 19 = 100 : 190

You have not mentioned if there is more than one answer so lets check the rest:

10 : 19 = (10 × 10.7) : (19 × 10 and 3/19)

10 : 19 ≠ 107 : 193

10 : 19 = (10 × 10.7) : (19 × 10)

10 : 19 ≠ 107 : 190

10 : 19 = (10 × 10) : (19 × 10 and 3/19)

10 : 19 ≠ 100 : 193

Answer:

Answer: Sin0 = 8/8.5

Step-by-step explanation:

Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).

The Sine of the angle is calculated as

Sin0 = opposite/hypotenuse

We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.

To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,

X² = 3² + 8²

X² = 9 + 64

X² = 73

Adding the square root sign to both sides of the equation, we now have

X = √73

X = 8.5 (approximately)

Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as

Sin0 = opposite/hypotenuse

Sin0 = 8/8.5

Answer:

The answer is p = 2.

Step-by-step explanation:

1) Divide both sides by 9.

[tex]p - 4 = - \frac{18}{9} [/tex]

2) Simplify 18/9 to 2.

[tex]p - 4 = - 2[/tex]

3) Add 4 to both sides.

[tex]p = - 2 + 4[/tex]

4) Simplify -2 + 4 to 2.

[tex]p = 2[/tex]

Therefor, the answer is p = 2.

Answer:

p =2

Step-by-step explanation:

9(p-4) =-18

9p-36=-18

9p = -18 +36

9p = 18

divide both side by 9

p =2

Answer:

45.7

Step-by-step explanation:

Hello there!

We can calculate the missing angle using trigonometry

here are the trigonometric ratios

sin = opposite over hypotenuse

cos = adjacent over hypotenuse

tan = opposite over adjacent

We are given x's opposite side length (8) and x's adjacent side length (7.8)

we are given the information to use the trigonometric ratio tangent

so now we create an equation (remember tan - opposite over tangent)

[tex]tan(x)=\frac{8}{7.8}[/tex]

now we solve for x

[tex]\frac{8}{7} =1.025641026[/tex]

we're left with

[tex]tan(x) =1.025641026[/tex]

finally we want to get rid of the tan

To do so we take the inverse of tan (arctan^-1) and apply it to each side

[tex]arctan^-^1tan(x)=x\\arctan^-^1(1.025641026)=45.7252243[/tex]

so x = 45.7252243

finally we round to the nearest tenth and get that the answer is
