Answer:
12 inches
Step-by-step explanation:
15 - 3 = 12
The board is 12 inches long.
_____
A measuring tape is like a number line. To find the distance between two numbers on the number line, you subtract the smaller one from the larger one. The tape measure works the same way. Subtract the number at one end of the board from the number at the other end of the board to find the length of the board.
If
represent a family of surfaces for different values of the constant
. The gradient of the function
defined as
is a vector normal to the surface
.
Given <span>the paraboloid
.
We can rewrite it as a scalar value function f as follows:
The normal to the </span><span>paraboloid at any point is given by:
Also, the normal to the given plane
is given by:
Equating the two normal vectors, we have:
</span>
Since, -1 = 2 is not possible, therefore
there exist no such point <span>
on the paraboloid such that the tangent plane is parallel to the plane 3x + 2y + 7z = 2</span>
.
Answer:
( 3 - 7i) • ( 2 - 5i) = ( - 29 - 29i)
Step-by-step explanation:
The formula is :
(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i
and since i^2 = -1 it can be written as :
ax - by + (ay + bx) i
( 3 - 7i) • ( 2 - 5i) =
( - 29 - 29i)
Answer:
At 75 MPH it would take 3 hours with no breaks. So go 3 hours and 30 minutes.
Step-by-step explanation:
225/75 = 3 Add break and traffic and go 3 1/2 hours.
Hi there! BF = 14
If AC = 19, the radius of circle C is 19.
In the picture we can see that AC = A F + CF.
Based on all the data we have we can fill in th: formula:
19 = A F + 12.
Subtract 12 from both sides.
7 = A F
A F = radius circle A = 7
BF, which is the diameter from circle A is two times the radius of the circle. Hence,
BF = 2 × A F = 2 × 7 = 14
~ Hope this helps you.
~ Note: there is a space between A F because the system doesn't accept is without a space (because of rude language).
