What is the value of 6 in 4.769
2 answers:
Answer: 6 hundredths.
Step-by-step explanation:
The given number is :
When we look at the given number from the left, we find that :
The place value of 4 = 4 ones [right most digit before decimal]
The place value of 7 is 7 tenths [left most digit after decimal]
The place value of 6 is 6 hundreds [rightmost to the tenth place]
The place value of 9 is 9 thousandths [rightmost to the hundredth place]
Hence, the place value of 6 in the given number is 6 hundredths.

Answer:
centre = (- 1, - 3 ) , radius = 6
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² + 2x + 6y = 26 ( collect x and y terms )
x² + 2x + y² + 6y = 26
using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(1)x + 1 + y² + 2(3)y + 9 = 26 + 1 + 9
(x + 1)² + (y + 3)² = 36 ← in standard form
with centre = (- 1, - 3 ) and r = = 6
For this case we have the following equation exponentially:
Where,
- <em>A: initial population </em>
- <em>b: growth rate </em>
- <em>t: time in years</em>
Then, replacing values for 32 years we have:
Answer:
the approximate population in 32 years is:
