Answer:
20.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
9 pi = 2 * pi *r
Divide each side by 2pi
9pi / 2 pi = 2 pi r / 2 pi
4.5 = r
Now we can find area
A = pi r^2
= pi ( 4.5)^2
20.25 pi
-- Find any point where y=4
-- Find another point where y=4
-- With your ruler, draw a line between the two points.
You have a horizontal line, and every point on it has y=4 no matter what 'x' is.
The equation for every straight line is [ y = mx+b ].
This is the line where (m = 0) and (b = 4).
Answer: A. 5,000 meters
Step-by-step explanation:
Starting with the smallest unit which is option C. There are 10 millimeters in one centimetre. Option c in centimeters is:
= 30,000 / 10
= 3,000 meters.
Option c is smaller than B and so is incorrect.
A meter is 100 centimeters. Option b in meters is;
= 6,000 / 100
= 60 meters
This is less than option A so is incorrect.
A kilometer is 1,000 meters so option A in meters is:
= 5,000 / 1,000
= 5 kilometers
This is higher than option d so option A is correct.
Red blue and white sperm cell, 3 points
how many chromosomes would reside in its somatic cells?
A = $12105; P = $19400; t = 3 (yrs)
Then $12105 = $19400(1-r)^3, or
0.6240 = (1-r)^3
Take the cube root of both sides. Then 0.854 = 1 - r, or r = 1 - 0.854 = 0.145 (answer) 0.145 is a decimal fraction.
