Answer:
1; -1
Step-by-step explanation:
As x approaches 0 from the left, the graph goes up to the point (0, 1), where the solid dot indicates that is the function definition for x=0.
As x approaches 0 from the right, the graph goes down toward the point (0, -1), to which it comes arbitrarily close. The limit from that direction is -1.
The two limits are +1 and -1.
Answer: 6*4=24 inches.
Step-by-step explanation:
The area of a rectangle can be found by multiplying the base times the height. If a rectangle has a base of length, 6 inches, and a height of 4 inches, its are is 6*4=24 square inches.

Answer:
m=28
Step-by-step explanation:
0.1(0.5m+6)=2
Distribute
.05m +.6 =2
Subtract .6 from each side
.05m +.6-.6 = 2-.6
.05m = 1.4
Divide each side by .05
.05m/.05 = 1.4/.05
m = 28
Answer:
See explanation below.
Step-by-step explanation:
The area of a plain domino equal the area of a 2-by-1 board, so it is easy to see that D4=4, D5=5, and so on.
Let's prove by induction than Dn=n for every natural number n.
1) Obviously, D1 is true.
2) Assume now that Dn is true for a given natural n, that is to say, a 2-by-n board can be covered with n dominoes.
<em>
we must prove that this implies D(n+1) is also true.
</em>
But the area of a 2-by-(n+1) board equals the area of a 2-by-n board plus the area of a 2-by-1 board.
By 2), we can cover the 2-by-n board with n dominoes and by 1) we can cover the 2-by-1 board with 1 domino, so we just need n+1 dominoes to cover the 2-by-(n+1) board, which is what we wanted to prove.
