Answer:
Step-by-step explanation:
The asnwer is B
Answer:
C
Step-by-step explanation:
When we talk of rate of change, we talk of the slope of the line
If we had a line;
y = mx + b
m is the slope ( which is the rate of change)
To get the slope of the line, we select any two points on the line and apply the slope formula
m = y2-y1/x2-x1
let us take points (0,0) and (3,9)
m = 9-0/3-0 = 9/3 = 3
The slope here is 3
so from the option, we can see that the third option is the correct answer
Answer: You will have $24,551.84 when you turn 18.
Step-by-step explanation:
Formula for accumulated amount earned in t years:
, where P = principal value, r = rate of interest
Given: P= $10000, r = 5% t = 18 years.
Substitute all values in formula, we get
Hence, you will have $24,551.84 when you turn 18.
Answer:
The complex number is 0+i/3.
Step-by-step explanation:
Let the imaginary part be x.
The complex number will be a+xi
Given:
real part =a
(a+xi)*3=i...............(i)
To find:
imaginary part
Solution:
3a + 3xi=i.............(ii)
Comparing real and imaginary parts of eq(ii).
3a=0 and 3x=1
a=0
x=1/3.
Answer:
255.61 inch³
Step-by-step explanation:
Volume of sphere is given by
V = 
πr³
Given that the original sphere had a radius of 5 cm, and that this is enlarged by a scale factor of 2, the new radius is
r = 5 cm x 2 = 10 cm
since 1 cm = 0.3937 inches, (need to convert to inches)
10 cm = 3.937 inches
hence r = 3.937 inches
V = x π x 3.937³
= 255.61 inch³
