What is the inverse function of f(x)=6x^3-3?

Answers

Answer 1

Answer: f(x)=6x^3-3

1. Replace f(x) with y: y = 6x^3 - 3
2. Interchange x and y: x = 6y^3 - 3 x+3 x+3
3. Solve this result for y: y^3 = --------- or y = cube root of -------
-1 6 6
4. Replace y with f (x)

O is the center of the circle. Assume that lines that appear to be tangent are tangent. What is the value of x?

Answers

Answer:

$\boxed{\boxed{x^(\circ)=78^(\circ)}}$

Step-by-step explanation:

Given that, O is the center of the circle and PQ is a tangent to the circle at point Q. OQ is a radius of the circle.

We know that, a tangent to a circle is a line which just touches the circle. And the angle between the tangent and radius is 90°.

Hence, ΔOQP is a right angle triangle. We know that the sum of the measurements of all the 3 angles of a triangle leads to 180°. So,

$\Rightarrow m\angle O+m\angle Q+m\angle P=180^(\circ)$

$\Rightarrow x^(\circ)+90^(\circ)+12^(\circ)=180^(\circ)$

$\Rightarrow x^(\circ)=180^(\circ)-90^(\circ)-12^(\circ)=78^(\circ)$

Angle q is right angle so you would first do 12+90=102 then you would do 180-102=78 so x=78

Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.

$\text{ tangent}^2=\text{whole secant}\cdot \text{exterior secant}$ .

The whole secant with exterior secant 5 in is 5+y in. Using this theorem you can state that

$9^2=(5+y)\cdot 5$ .

Solve this equation:

$81=25+5y,\n 5y=81-25,\n 5y=56,\n y=11.2$ in.

Answer: y=11.2 in.

Write an expression for the total cost, in pounds, of: X jumpers at £15 each and y shirts at £12 each

Answers

x jumpers at £15 each. Total = 15*x = £15x

y shirts at £12 each. Total = 12*y = £12y

Total cost = £15x + £12y

Total cost = £(15x + 12y)

Final answer:

The total cost, in pounds, for X jumpers at £15 each and Y shirts at £12 each can be written as the mathematical expression: 15X + 12Y, where X and Y are the quantities of jumpers and shirts respectively.

Explanation:

To write an expression for the total cost of X jumpers at £15 each and Y shirts at £12 each in pounds, you need to multiply the cost per item by the quantity of each items and then add these two products together.

So, the total cost can be given as:

15X + 12Y

where

X represents the number of jumpers
Y represents the number of shirts

In this expression, '15X' stands for the total cost of the jumpers and '12Y' stands for the total cost of the shirts.
