Yasmin's puppy, maggie, weighed 14 ounces at birth. she doubled her birth weight in 10 days. assuming her growth is constant, how much will she weigh at various times in the first year?

we are given growth rate is  constnat

so, equation wil be straight line

Yasmin's puppy, maggie, weighed 14 ounces at birth

Let's assume weight after t days as w

t is time in days

so, we get (0,14)

She doubled her birth weight in 10 days

so, we get (10, 28)

Firstly, we will find slope

(0,14)

x1=0, y1=14

(10, 28)

x2=10 , y2=28

we can use it and find m

now, we can use point slope form of line

we know that

1 year =365 days

so, we can plug t=365

so, weight after 1 year is 525 ounces.........Answer

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
