Answer:
linear
Step-by-step explanation:
use Desmos can help A LOT
X-doubling periods
Y-height of bamboo
Y=ab^x
1) make a table of values
X Y
1 5
2 10
3 20
2) write equations and substitute
5=ab^1 —> a=5/b^1 —> a=5/b
10=ab^2
Substitute into second equation
10=(5/b)*b^2
10=5b^2/b
10=5b
b=2
Substitute back in
b=2
10=a*2^2
10=4a
a=5/2
End equation:
Y=5/2*2^x
Answer:
0.15kg
Step-by-step explanation:
Given data
We are told that
0.75 kg of cortos weights 5times the mas of the onion
We want to find the mass of 1 onion
Hence
0.75 kgcortos = 5 onions
x cortos = 1 onions
x= 0.75/5
x= 0.15kg
Hence 1 onion will weigh 0.15kg
They are all perfect squares
(9x+2)(9x+20
(9x+2)^2
Answer:
$ 157838.60 in 5 years
Step-by-step explanation:
r = 1.06
sum of geometric seq = a1 ( 1-r^n)/(1-r) n = 5
28000 ( 1 - 1.06^5) / ( 1-1.06) = 157838.60
