Answer:
Step-by-step explanation:
a: A(4,-3) B(4,-1) C(1,-1) D(1,-3)
b: A(-4,3) B(-4,1) C(-1,1) D(-1, 3)
c:yes because you are just changing the direction not the shape or size
The numbers 1 to 72 add up to (1+72) x 72/2 = 73 x 36 = 2628
If we take away what Josh got we have 2628 - 2521 = 107
Pages in a book are odd on the first side and even on the second, so pages 11 and 12 are on the same sheet.
107 / 2 = 53.5 so the missing page had 53 on one side and 54 on the other side.
The remaining pages would have been numbered 1, 2, 3, ..., 51, 52, 55, 56, ... 71, 72
Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>It can be rewritten as:</u>
- v(d) = 2^d, where d- number of divisions
<u>If number of divisions is 8, then:</u>
- v(8) = 2^8 = 256 virus cells
Correct choice is B
Answer:
∠ DAB = 48°
Step-by-step explanation:
The sum of the 3 angles in Δ ACD = 180° , then
∠ CAD + 60° + 90° = 180° , that is
∠ CAD + 150° = 180° ( subtract 150° from both sides )
∠ CAD = 30°
Then
∠ DAB + ∠ CAD = ∠ CAB
∠ DAB + 30° = 78° ( subtract 30° from both sides )
∠ DAB = 48°
