Answer:

f^{-1} (x) = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }

Step-by-step explanation:

Let f(x) = y

Interchange x and y so

x = \frac{1}{\sqrt{y^{3} + 9 } }

x\sqrt{y^{3} + 9}  = 1

\sqrt{y^{3} + 9 }  = \frac{1}{x}

y^{3}  + 9 = \frac{1}{x^{2} }

y^{3}  =  \frac{1}{x^{2} }  - 9 = \frac{1 - 9x^{2} }{x^{2} }

y = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }

f^{-1} (x) = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }

The total amount spent on gas is $9.

<h3>How much is spent on gas?</h3>

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. Multiplication is the method that is used to add a number by itself a particular number of times. The sign used to denote multiplication is x. Other mathematical operations are subtraction, division and addition.

In order to determine the total amount spent on gas, multiply the cost of one gallon by the number of hours skied and the amount of galloons used per hour.

The total amount spent on gas = cost of one gallon of gas x number of hours skied x number of gallons used per hour

2 x 3 x $2.25 = $9

The square of a number plus three times the number is 70. find the numbers.
Harrizon [31]

Answer:

Step-by-step explanation:

The equation for that is

x^2+3x=70

If we subtract over the 70, we have a quadratic that we can factor to solve for the values of x that will make that equation true.

x^2+3x-70=0

Now we need the factors of 70 that will either add or subtract to give us the linear term of 3. The factors of 70 that will work are 10 and 7. 10 times 7 is 70, and 10 - 7 = 3:

x^2+10x-7x-70=0 and now we will factor by grouping:

(x^2+10x)-(7x-70)=0 and factor out what's common:

x(x+10)-7(x+10)=0

The factor (x + 10) is common, so we will now factor that out:

(x+10)(x-7)=0

By the Zero Product Property, either x + 10 = 0 or x - 7 = 0, so x = -10 or 7

Those are the 2 numbers that will work.

(-10)^2+3(-10)=70 simplifies to

100 - 30 which does in fact equal 70. OR

(7)^2+3(7)=70 which simplifies to

49 + 21 which also equals 70.

So you're done!

If the measure of ZB is 40°, what measures can ZA and
lubasha [3.4K]

Answer: 30° and 110°

55° and 85°

70° and 70°

The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:

= 180° - 40°

= 140°

Therefore,

30° + 110° = 140°

55° + 85° = 140°

70° + 70° = 140°
