Let the width =x
length = 6x
p=14x
28=14x
x=2
Answer:
x=2±16i
Step-by-step explanation:
1.) Using the PEMDAS distribute the using the FOIL method
2.) Distribute the -16 to ()
3.) Add the -25 to the equation
=0
4.) Since this isn't factor-able, you must use the quadratic formula,
and distrubute the numbers
a=-16 b=64 and c=-89
5.) Simplify the radical by finding the factors of -18688 that has a perfect root as one of the factors (which is -256 and 73).
6.)Simplify the fraction
7.) Your two roots are:
{2}(+ or -)16i\sqrt{73}
Answer:
Step-by-step explanation:
3=7k
Meaning k = 3/7
7=m/2
Meaning m = 7*2 = 14
Therefore mk = 3/7*14 = 6
Answer:
Step-by-step explanation:
To find the equation of a sphere with center (2,-3,6) that touch
(a) the xy-plane,
The equation of xy plane is z=0
Hence the radius would be distance from z=0 perpendicular to xy plane = z coordinate =6
Equation is
(b) the yz-plane,
The equation of yz plane is x=0
Hence the radius would be distance from x=0 perpendicular to yz plane = x coordinate =2
Equation is
(c) the xz-plane.
The equation of zx plane is y=0
Hence the radius would be distance from y=0 perpendicular to zx plane = |y coordinate| =3
Equation is
