$f (x)=(x-1)^3 \\ y =(x-1)^3 \\\\\sf Replace~ x ~with~ y ~and~ vice~ versa \\ x = (y-1)^3 \\ \sqrt[3]{x} =y-1 \\ \\ Solve~for~y\\\\ \boxed {y= \sqrt[3]{x} +1}$

Given the side lengths, determine whether the triangle is acute, right, obtuse, or not a triangle.

mina [271]

It’s obtuse

Explanation:
Assign the sides by length with c being longest
If (a^2)+(b^2)>(c^2) it’s acute

If (a^2)+(b^2)=(c^2) it’s right

And if (a^2)+(b^2)<(c^2) it’s obtuse

Since (3^2)+(9^2)=9+81=90
And 10^2=100 we know that (a^2)+(b^2)<(c^2) so it’s obtuse

Apen cost 20php each, if you buy more than 10pens you will be given 50percent discount on the next pens you're about to buy. mak

vredina [299]

Cost of pen = 20x when x< 10

and

=10x when x>10

Let the number of pens bought be x.

So the total pen cost is 20x when the number of the pen is less than 10.

Now let's take that the number of pens bought is more than 10

So the pen will cost a 50% discount

50% of 20x

= 20/100 × 20x

= 10x

So the cost of the pen will be 10x when the number of the pen is greater than 10.

From this, we get to know that

Cost of pen = 20x when x<10

and

= 10x when x>10

Find the area of the regular polygon.

Charra [1.4K]

Answer:

98 yd²

Step-by-step explanation:

From the diagram attached, The polygon is a square with the distance from the edge of the square to the center of the square = 7 yd.

The distance from the edge of the square to the center of the square is half of the diagonal. Therefore length of the diagonal = (7 yd * 2) = 14 yd

The diagonal and two sides of the triangle form a right angle triangle. Let the side of the triangle be a. Therefore the hypotenuse is the diagonal, using Pythagoras theorem:

a² + a² = 14²

2a² = 196

a² = 98

a = √98 = 7√2

The length of the side of the triangle = a = 7√2 yd

The area of the rectangle = length × length = 7√2 × 7√2 = 98 yd²
