The population will reach 540 000 in 30.8 yr.
The formula for population growth is
<em>P</em>_<em>t</em> = <em>P</em>_0 × e^(<em>rt</em>)
540 000 = 270 000 × e^(0.0225t)
e^(0.0225t) = 2
0.0225t = ln2
t = (ln2)/0.0225 = 30.8
Use--> m=y2-y1/x2-x1
10. (0,-1), (2,3)
3--1=4/2-0=2
4/2=2
11. 7/10
12. -1/3
Answer:
It’s either A or B
Step-by-step explanation:
Pretty sure it’s A though
Base of pyramid, a = 756 ft
= 252 yards (1 ft = 0.333 yards)
Height of pyramid, h = 480 ft
= 160 yards
(a). For a square pyramid, we have:
Volume = 
= 
= 33,86,880 cubic yards
Hence, volume of the Great Pyramid = 33,86,880 cubic yards
(b). Volume of limestone block = 1.5 cubic yards
Number of limestone blocks needed to construct the Great Pyramid = Volume of pyramid / volume of limestone block
= 33,86,880 / 1.5
= 22,57,920 limestone blocks

y = 6x + -7 / y = -7 + 6x
Solving
y = -7 + 6x
Solving for variable 'y'.
Move terms containing y to the left, other terms to the right. y = -7 + 6x hope this helps </span>
