Answer:
730
Step-by-step explanation:
A(X)= 2πRH+2πR^2
A(X)=2π(7.5)(8)+2π(7.5)^2=730.42 = 730
Rewrite = so is on the left side.
You reverse what you did, so first you go 5 units down which makes the coordinates (9,1) then you move 3 units left which then is (6,1). Then you go 4 units up which lets you end out at (6,5).
Answer:
12/13
Step-by-step explanation:
By definition, for a right triangle with an internal angle X
sin X = length of opposite side / length of hypotenuse
in this case,
for angle F, the opposite side = GH and the hypotenuse is HF
hence
sin F = GH / HF = 12/13
Log (7/4) is equivalent to log (7.7/4.4), therefore it's log(7.7) - log(4.4), or...
2.0142 - 1.4816 = 0.5326
