Answer:
x = 5/4
Step-by-step explanation:
√2+√2+√2+√2 = 2^x
4√2 = 2^x
4√2 =
= ![2^{x}](https://tex.z-dn.net/?f=2%5E%7Bx%7D)
x = 5/2
Answer:
The square roots of 400 are 20 and -20.
Step-by-step explanation:
You can try the offered answers to see if they square to give 400:
(-40)² = 1600 . . . . -40 is not a square root of 400
(-20)² = 400 . . . . -20 is a square root of 400
20² = 400 . . . . . 20 is a square root of 400
40² = 1600 . . . . 40 is not a square root of 400
_____
The second degree equation ...
x² = 400
will have exactly two solutions, as required by the fundamental theorem of algebra. Those solutions are both given above. There are no other square roots of 400, real or complex.
A=1/2 * d1 * d2
a=1/2 * 2.7 * 3.2= 4.32mm
Answer:
A. The selection is a combination.
Step-by-step explanation:
A combination is a selection of all or part of a set of objects, without regard to the order in which they were selected.
Then, a permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement.
For example, the student scans the novels to be checked out in no particular order hence it is a combinations problem. Scanning novels with titles A, B, C, D and E in the order B, C, D, E and then A produces the same result. When it comes to library books, the order in which we scan the novels for check out is of no importance since in the end the same novels are carried out the door by the library patron.
Length = 50
Width = 3.2
Area= 160
Formula
A=w*l
A=3.2×50
=160
I believe hope I'm right
