Answer:

x = 3

Step-by-step explanation:

This is a vertical line parallel to the y- axis with general equation

x = c

c is a constant and is the value of the x- coordinates the line passes through.

In this case the line passes through all point with an x- coordinate of 3

Hence equation is x = 3

Answer:

x = 3

Step-by-step explanation:

Things to note:

The line is going up and down
The line is intersecting with the x axis and 3

Therefore, we can conclude the equation of the line is x = 3

Answer:

I think it is 40% (Not sure)

Step-by-step explanation:

First, you want to find out how much percent is in one square. To find that out you divide 5 by 100 because 100 is basically 1 in this situation. 100/5 is equal to 20% so that means any one part (Shaded or not) is 20%. Then add the shaded squared up and you get 40%.

2. Carissa also has a sink that is shaped like a half-sphere. The sink has a volume of 3617 in? One day, her

Juliette [100K]

Answer:

863 cups

Step-by-step explanation:

step 1

Find the volume of the conical cup

The volume of the cone (cup) is equal to

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=2/2=1\ in$ ----> the radius is half the diameter

$h=4\ in$

assume

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(1^{2})4=4.19\ in^3$

step 2

Find out how many cups of water must Carissa scoop out of the sink

Divide the volume of the sink by the volume of the cup

so

$\frac{3,617}{4.19}= 863\ cups$

Find the tangent plane to the given surface of f(x,y)=6- 6/5 x-y at the point (5, -1, 1). Make sure tat your final answer for th

HACTEHA [7]

Answer:

Required equation of tangent plane is $z=\frac{6}{5}(x-5y-11)$ .

Step-by-step explanation:

Given surface function is,

$f(x,y)=6-\frac{6}{5}(x-y)$

To find tangent plane at the point (5,-1,1).

We know equation of tangent plane at the point $(x_0,y_0,z_0)[/tex] is,

$z=f(x_0,y_0)+f_x(x_0,y_0)(x-x_0)+f_y(x_0,y_0)(y-y_0)\hfill (1)$

So that,

$f(x_0,y_0)=6-\frac{6}{5}(5+1)=-\frac{6}{5}$

$f_x=-\frac{6}{5}y\implies f_x(5,-1,1)=\frac{6}{5}$

$f_y=-\frac{6}{5}x\implies f_y(5,-1,1)=-6$

Substitute all these values in (1) we get,

$z=\frac{6}{5}(x-5)-6(y+1)-\frac{6}{5}$

$\therefore z=\frac{6}{5}(x-5y-11)$

Which is the required euation of tangent plane.
