The function represents exponential growth with the initial value equal to 1, the decay factor equal to 0.3, and the rate equal to 0.7.
<h3>Population Growth Equation</h3>
The formula for the Population Growth Equation is:
Pf= future population
Po=initial population
r=growth rate
t= time (years)
growth or decay factor = (1 ±r)
When 1+R > 1, the equation represents growth, while 1+R < 1 the equation represents decay.
The question gives:
, then
Pf=y
Po= 1
, thus
r= -70%= -0.7
decay factor= (1-0.7)=0.3
Therefore,
1+R will be = 1+(-0.7)=1 - 0.7 =0.3
When 1+R >1, the function represents exponential growth.

Step-by-step explanation:
use bidmas (brackets,indices, division,multiplication,addition,substraction)
Answer:
y = 1/3x + 10/3
Step-by-step explanation:
→ Write gradient into format
y = 1/3x + c
→ Substitute in (5,5)
5 = 5/3 + c
→ Find c
c = 5 - 5/3 = 10/3
→ Finish off
y = 1/3x + 10/3
I'm not sure if you need the answer or just the steps to start, so I will just give u the steps. First, just take a step back and take it one step at a time. Once you have an idea of how the two triangles are congruent, make 2 columns, one with statements and one with reasons. On the statements side, put given information and what you learn along the way, like if it is given x=y, and y=z, then what you can put down after that is x=z. On the reasons side, put the properties or formulas you used to reach your solution. For instance, if x=y and y=z, x=z by the Transitive property of equality. Proofs are time consuming, tedious and utterly frustrating. Just take it slowly and you will be fine.
Yes they will be equal at some point. Although Marc has more miles on his car at the current moment, Elena is adding miles at a higher rate.
Elena's car: 7000 + 21000t
Marc's car: 20000 + 11000t
To find at what time t they are equal, set these two expressions equal to each other and solve for t.
7000 + 21000t = 20000 + 11000t
13000 = 10000t
t = 1.3 years from now
