answer:
6 more hundreds
step-by-step explanation:
- six hundreds mean 600
- 600 + 400 would be 1000
- therefore, we would need 6 more hundreds
7.2352297363 rounded to the nearest millionth would be 7.235230 and all I did to get the answer was count from left to right and keep the first six numbers, and round 229 up one spot and make it 230, to get the answer.
f(x)= x^2 -6x +21
0 =x^2-6x+21
subtract 21 from each side to prepare for completing the square
-21 = x^2 -6x
completing the square (b/2)^2
(-6/2) ^ =3^2 = 9
add 9 to each side
-21 +9 = x^2 - 6x + 9
-21 +9 =(x-3) ^2
-12 = (x-3)^2
take the square root of each side
+- sqrt(-12) = x-3
add 3 to each side, take out the negative inside the square root
3 +- i sqrt(12)=x
simplify the square root sqrt(12)= sqrt(4)sqrt(3) =2sqrt(3)
3 +- i 2sqrt (3) = x
Answer: 3+2isqrt(3)
3-2isqrt(3)
Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- percent
- percentage words problem
- PEMDAS
<h3>given:</h3>
- population:2500
- decreasing rate:3%
<h3>to find:</h3>
- the population after 11 years
<h3>let's solve:</h3>
according to the question
population decreases in 1 year
population will decrease in 11 years
so the population of the town after 11 years will be
2500-825
<h2>1675</h2>
