You want to buy a trampoline. You found one online that has a circumference of 6.28 yards. What is the area?

gizmo_the_mogwai [7]

The area of the trampoline is mathematically given as

a = 3.14

Question Parameters:

You found one online that has a circumference of 6.28 yards

Generally, the equation for the Circumference is mathematically given as

C = 2*pi*r

Thererfore

6.28 = 2*3.14*r

r = (6.28)/(6.28)

r = 1

In conclusion, where radius is

$a= pi*r^2$

a = 3.14*1^2

a = 3.14

Find f if f′(x)=2x−3/x^4, x>0 and f(1)=2.

slavikrds [6]

$f'(x)=2x-\dfrac3{x^4}$
$\displaystyle\int f'(x)\,\mathrm dx=\int\left(2x-\frac3{x^4}\right)\,\mathrm dx$
$f(x)=x^2+\dfrac1{x^3}+C$

Given that $f(1)=2$ , we get

$2=1^2+\dfrac1{1^3}+C$
$2=2+C$
$\implies C=2$

so that

$f(x)=x^2+\dfrac1{x^3}$

Coefficient of x^2 in the expansion of (x-3)^3

Mila [183]

Answer:

$-9$

Step-by-step explanation:

$(x-3)(x-3)(x-3)$

$(x^2-6x+9)(x-3)$

$x^3-9x^2+27x-27$

Therefore, the coefficient of $x^2$ is $-9$ .
