We know that
perimeter of the figure=perimeter of semi circle+perimeter of rectangle
so
perimeter of semicircle=2*pi*r/2----> pi*r
diameter=6 yd
radius r=6/2----> r=3 yd

convert to ft
1 yd ------> is equal to 3 ft
3 yd-----> x
x=3*3----> x=9 ft
so
diameter=18 ft
radius=9 ft
perimeter of semicircle=pi*9----> 28.26 ft

perimeter of rectangle=18+15+15----> 48 ft

perimeter of the figure=28.26 ft+48 ft-----> 76.26 ft

the answer is
<span>76.26 ft</span>

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

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

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

How to find the derivative of e^3㏑(x²)

vovikov84 [41]

$f(x)=e^{3\ln x^2}\\\\f'(x)=e^{3\ln x^2}\cdot\dfrac{3}{x^2}\cdot2x=e^{3\ln x^2}\cdot\dfrac{6}{x}=\dfrac{6e^{3\ln x^2}}{x}\\\\\\but\ e^{3\ln x^2}=e^{\ln (x^2)^3}=e^{\ln x^6}=x^6\ where\ x\neq0\\\\therefore\ f'(x)=6x^5$
