Answer:
y = 320,000(2.1)^t
Step-by-step explanation:
uhm, im not very good at explaining, but everytime the year increases, the population will exponentially increase, that's why 't' is an exponent
To increase something by x% mulitply it by (1+x)
in other words, to increase sometihng by 2.1% mulitply it by
(1+.021) or 1.021
because we are mulitplying 320000 by 1.021 each year we can write the equation as
y=320000(1.021)^t
1. 24
2. B
1. 7^2+x^2=25^2
49+x^2=625
x^2=576
x=24
2. 15^2+36^2=39^2
225 + 1296 = 1521
24^2 + 7^2 = 576 + 49 = 625
one side of a kite = √625 = 25
7^2 + 4^2 = 49 + 16 = 65
other side = √65 = 8.06
The perimeter of the kite = 2(25) + 2(8.06)
= 50 + 16.12
= 66.12
Answer
P = 66.12 cm
