It would be: 8+5 - 6 = 13-6 = 7

So, Final Answer is 7

Hope this helps!

First you add 8+5 because there the sum and subtract 6 13-6=7

So it's 7

Find the midpoint of the line segment joining the points P1 and P2.

Karolina [17]

Answer:

M= (1, 7/2)

Step-by-step explanation:

M = midpoint

M= ((x1+x2)/2) , ((y1+y2)/2)

we have:

P1 = (4,2)

P2 = (-2,5)

x1= 4 y1= 2

x2= -2 y2= 5

we have:

M= ((4-2)/2) , ((2+5)/2)

M= (2/2 , 7/2)

M= (1, 7/2)

murzikaleks [220]

Answer:

$x-4y+4=0$

$f(x)=\sqrt x$ and x=4

Step-by-step explanation:

We are given that a curve

$y=\sqrt x$

We have to find the equation of tangent at point (4,2) on the given curve.

Let y=f(x)

Differentiate w.r.t x

$f'(x)=\frac{dy}{dx}=\frac{1}{2\sqrt x}$

By using the formula $\frac{d(\sqrt x)}{dx}=\frac{1}{2\sqrt x}$

Substitute x=4

Slope of tangent

$m=f'(x)=\frac{1}{2\sqrt 4}=\frac{1}{2\times 2}=\frac{1}{4}$

In given question

$m=\lim_{x\rightarrow a}\frac{f(x)-f(a)}{x-a}$

$\frac{1}{4}=\lim_{x\rightarrow 4}\frac{f(x)-f(4)}{x-4}$

By comparing we get a=4

Point-slope form

$y-y_1=m(x-x_1)$

Using the formula

The equation of tangent at point (4,2)

$y-2=\frac{1}{4}(x-4)$

$4y-8=x-4$

$x-4y-4+8=0$

$x-4y+4=0$
