1, 4, 9, 16, 25, 36, and 49 because 1*1=1, 2*2=4, 3*3=9, 4*4=16, 5*5=25, 6*6=36, and 7*7=49
Answer:
Step-by-step explanation:
If you treat 90° as 1 unit on the graph, then
P(1,0) corresponds to (0,0) and (360,0) on the sin graph (say (0,0) though)
P(0,1) corresponds to (90,1) on the sin graph
P(-1,0) corresponds to (180,0) on the sin graph
P(0,-1) corresponds to (270,-1) on the sin graph
2b - 4 ≥ 2 ; [1,2,3,4]
Plug in each number for "b" in the inequality
2(1) - 4 ≥ 2
2 - 4 ≥ 2
-2 ≥ 2
1 is not a solution because -2 is not greater than or equal to 2.
2(2) - 4 ≥ 2
4 - 4 ≥ 2
0 ≥ 2
2 is not a solution because 0 is not greater than or equal to 2.
2(3) - 4 ≥ 2
6 - 4 ≥ 2
2 ≥ 2
3 is a solution because 2 is equal to 2.
2(4) - 4 ≥ 2
8 - 4 ≥ 2
4 ≥ 2
4 is a solution because 4 is greater than 2.
{3, 4} is your answer
Answer:
x=2.45
Step-by-step explanation:
9/(x-11)=3
x9 x9 ( multiply by 9 on each side)
x-11= 27
/11 /11 ( divide by 11 on each side)
x=2.45
Happy Holidays :)
