Using first principal find the gradient of the curve whose equation is y=x^5. show working pleas

Keith_Richards [23]

Answer:

The gradient of $y = x^{5}$ is $\frac{dy}{dx} = 5\cdot x^{4}$ .

Step-by-step explanation:

Geometrically speaking, the gradient of a curve is the slope of the tangent line at a given point of the curve. From perspective of Differential Calculus, the gradient is the first derivative of the curve. Let $y = x^{5}$ , then the gradient of the curve is:

$\frac{dy}{dx} = 5\cdot x^{4}$ (1)

The gradient of $y = x^{5}$ is $\frac{dy}{dx} = 5\cdot x^{4}$ .

The side of a equilatoral triangle is 9.9 cm. find its perimetre

tia_tia [17]

The perimeter is the distance all the way around.

That's the sum of all the sides.

A triangle has 3 sides.

In an equilateral triangle, they're all the same length.

If one of them is 9.9 cm, then all of them add up to (3) · (9.9 cm) .
