Answer:
I believe it is $65
Step-by-step explanation:
$55/5.5
Divide the $55 by 5.5 and you get $10, then add it to your original $55, that makes $65, right?
.67*8.7= 5.829
Estimated is about 5.8 or 6
Answer:
Step-by-step explanation:
-20=2(n-3)
-20=2*n-2*3
-20=2n-6
-20+6-2n
-14/2=n
-7=n
Radius, r = 3
The equation of a sphere entered at the origin in cartesian coordinates is
x^2 + y^2 + z^2 = r^2
That in spherical coordinates is:
x = rcos(theta)*sin(phi)
y= r sin(theta)*sin(phi)
z = rcos(phi)
where you can make u = r cos(phi) to obtain the parametrical equations
x = √[r^2 - u^2] cos(theta)
y = √[r^2 - u^2] sin (theta)
z = u
where theta goes from 0 to 2π and u goes from -r to r.
In our case r = 3, so the parametrical equations are:
Answer:
x = √[9 - u^2] cos(theta)
y = √[9 - u^2] sin (theta)
z = u
Answer: 1308m
Step-by-step explanation:
Top and Bottom: 19 x 16 x 2 = 608
Sides: 16 x 10 x 2 = 320
Front and Back: 19 x 10 x 2 = 380
608 + 320 + 380 = 1308
