A curve has equation y=x√x.find the equation of the tangent to the curve at the point(1, 5)
rewona [7]

Answer:

y - 5 = \frac{3}{2}(x - 1)

Step-by-step explanation:

Note that \frac{dy}{dx} = m_{tangent}

Differentiate using the power rule

\frac{d}{dx}(ax^{n}) = nax^{n-1}

Given

y = x\sqrt{x} = x. x^{\frac{1}{2} } = x^{\frac{3}{2} }, then

\frac{dy}{dx} = \frac{3}{2}x^{\frac{1}{2} }

When x = 1

\frac{dy}{dx} = \frac{3}{2} . 1 = \frac{3}{2}

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = \frac{3}{2} and (a, b) = (1, 5), thus

y - 5 = \frac{3}{2}(x - 1) ← equation of tangent

in Math class we are Learning about Pi which equals 3.14 how do you find the diameter and radius i dont understand it can you gu
kirill [66]
If you're finding diameter or radius based on circumference, use the formula C = πd. You would divide the circumference by pi to get the diameter, then divide the diameter by 2 to get the radius.

If you're finding diameter or radius based on area, use the formula A = πr^2. You would divide the area by pi, then find the square root of that value which is the radius. Just multiply the radius by 2 to find diameter.
