Answer:
Step-by-step explanation:
11. Write in point slope form first;
y+4 = (x+1)^2; Convert to standard form;
y=x^2+2x+1-4
y = x^2+2x-3; Final standard form
12. Convert the original point-slope form with the vertex given;
y-3 = a(x-4)^2; plug in the point (1,12) to solve for a;
12 -3 = a(1-4)^2
9 = 9a
a = 1
y-3 = (x-4)^2
y=(x-4)^2+3: Final vertex from
13. The vertex is at (-1,-4)
y +4= (x+1)^2; Factored form can mean many things;
this is the equation of the function; factor it how your teacher taught you.
Answer:
total population in the year 2000=4400
total population in the year 2010=5060
no of people increased=5060-4400
=660
increase percent=660/4400*100%
=3/20*100%
=15%
Step-by-step explanation:
15/100*5060
0.15*5060
759
in 2020 population will be
5060+759
5819
therefore the population will be 5819 in 2020
Answer:
20π or 62.8 roughly
Step-by-step explanation:
Hello!
<u>The formula for finding the circumference of a circle is 2rπ:</u>
In that case, all we have to do is substitute 10m for our r.
2 × 10 = 20.
So circumference will be 20π.
Using 3.14 for π:
We get that 62.8 is a rough estimate for the circumference.
Really, it's 62.831..... going on forever since π is irrational.
Thus, the answer exactly is 
.
Hope this helps!
Answer 56m/s
Step-by-step explanation:
7m x 1000
= 7000KM
7000KM : 125
= 56 m/s
