Find the gradient, picture below

hoa [83]

Answer:

$\frac{dy}{dx} = \frac{13}{8}$

Step-by-step explanation:

$y = 2x + 6 {x}^{ - \frac{1}{2} } \\ \frac{dy}{dx} = 2 + 6( - \frac{1}{2}) {x}^{ - \frac{1}{2} - 1 } \\ \frac{dy}{dx} = 2 - 3 {x}^{ - \frac{3}{2} } \\ \frac{dy}{dx} = 2 - \frac{3}{ \sqrt{ {x}^{3} } }$

When x = 4,

$\frac{dy}{dx} = 2 - \frac{3}{ \sqrt{ {4}^{3} } } \\ = \frac{13}{8}$

Find the volume of the following

Nadusha1986 [10]

Given:

A prism with right triangular base.

Base of triangle = 6 ft

Height of triangle = 8 ft

Height of prism = 7

To find:

The volume of the given prism.

Solution:

The volume of prism is:

$V=Bh$ ...(i)

Where, B is the base area and h is the height of the prism.

In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:

$B=\dfrac{1}{2}\times base\times height$

$B=\dfrac{1}{2}\times 6\times 8$

$B=\dfrac{48}{2}$

$B=24$

Substituting $B=24,\ h=7$ in (i), we get

$V=24\times 7$

$V=168$

Therefore, the volume of the prism is 168 cubic ft.

What are the coordinates of the roots of the equation x^2+ 4x + 3 = 0 ?

bagirrra123 [75]

Answer:

Step-by-step explanation:

1) Factor out the x components of the equation

(x+3)(x+1)=0

2) Take each individual term and find the value for which the equation equals zero:

x+3=0 -> x=-3

x+1=0 -> x=-1

x = -3, -1
