Cartesian coordinates are- 4.2426

The horizontal component of the Cartesian coordinate system is denoted by the letter x, whereas the vertical component is denoted by the letter y. In this coordinate system, equations for lines will need to include both the x and y variables.

Given

(r,θ) = (6,π/4)

x= r cosθ =6 x cos(π/4)
= 6√2 = 3√2

≈ 4.2426

y= r sinθ = 6 x sin(π/4)

= 6√2 = 3√2

≈ 4.2426

Hence the answer is 4.2426

A car dealership pays you 4% commission on your first $8000 in car sales and 8% commission on sales over $8000. If you made $900

mart [117]

To do this you would first calculate the 4% commission:
0.04 *8000 = 320.

And then the 8% commission:
0.08 * (9000 - 8000) = 80.

Now you add the two values together to get the answer, 320 + 80 = 400.

Your commission would be $400.

Hope this helps.

Yes, the triangle is right angled.

Step-by-step explanation:

Given lengths are;

11 yards, 60 yards and 61 yards

From pythagoras theorem;

The sum of square of shorter lengths is equal to square of larger side.

Here;

a = 11 , b = 60 , c = 61

$a^2+b^2=c^2\\(11)^2+(60)^2=(61)^2\\121+3600=3721\\3721=3721$

As it satisfies the condition of Pythagoras theorem, the triangle is right angled.

Yes, the triangle is right angled.

Find the volume of the solid obtained by rotating the region bounded by the given curves about the speciﬁed axis. y = 64x−8x^2,

Mandarinka [93]

We need to get the limits first. When y = 0
0 = 64x - 8x^2
x = 0 and x = 8
The volume is
V = ∫ y dx from 0 to 8
V = ∫ (64x - 8x^2) dx from 0 to 8
V = 32x^2 - 8x^3/3 from 0 to 8
V = 682.67
