find the component equation of the plane which is normal to the vector -2i+5j+k and which contains the point (-10;7;5).

maksim [4K]

Given:

A plane is normal to the vector = -2i+5j+k

It contains the point (-10,7,5).

To find:

The component equation of the plane.

Solution:

The equation of plane is

$a(x-x_0)+b(y-y_0)+c(z-z_0)=0$

Where, $(x_0,y_0,z_0)$ is the point on the plane and $\left< a,b,c\right>$ is normal vector.

Normal vector is -2i+5j+k and plane passes through (-10,7,5). So, the equation of the plane is

$-2(x-(-10))+5(y-7)+1(z-5)=0$

$-2(x+10)+5y-35+z-5=0$

$-2x-20+5y-35+z-5=0$

$-2x+5y+z-60=0$

$-2x+5y+z=60$

Therefore, the equation of the plane is $-2x+5y+z=60$ .

What is the height of a triangle that has an area of 60 yards^2 and a base of a length of 12 yards?

zmey [24]

For a triangle:
$A=\frac{b \times h}{2}$
$60=\frac{12\times h}{2}$
$120=12h$
$h=\frac{120}{12}$
$h=10yrd$

HELP‼️<br> if ABC=DEF and GHI=JKL, is ABC=JKL? why or why not?

DENIUS [597]

Step-by-step explanation:

no, we have no way to prove that they are equal. is DEF equaled JKL then ABC would be equal to it, but it's not
