Answer:
a 2.68
b 2.01
Step-by-step explanation:
1.34/2 =( 0.67 (F) )
(F)*4 = A
(F)*3 = B
When you draw a horizontal line through the given solution point, you find it intersects the unit circle at 150°. Thus the appropriate choice for the remaining solutions will be
... 30° + n•360°, 150° + n•360°
Answer:
172 ft 2
Step-by-step explanation:
SA=2lw+2lh+2hw, for
A=2(lw + lh + hw)=2·(7 · 2+ 8 · 2 + 8 · 7)= 172 ft 2.
Hope this helps,
Best of Luck!
Answer:
Step-by-step explanation:
The formula for a geometric sequence is where is the th term of the sequence, is the first term, and is the common ratio.
Since each term is being multiplied by 3, this is our common ratio.
Therefore, our geometric sequence formula is
Use the Difference of Two Squares Formula,
If x² = 4x², then x = √4x², x = 2x
If y² = 49, then y = √49, y = 7
We know both x and y, straight to formula.
Therefore, the factored form of 4x²-49 is (2x+7)(2x-7)
