Answer:
Step-by-step explanation:
Mr Samuel Planted 40 pepper plants in 2005.
Therefore:
f(0)=40
Each year the number of pepper plants doubled.
In 2006, f(1)=40*2
In 2007, f(2)=40*2*2
In 2008, f(3)=40*2*2*2
If we continue in like manner. The number of pepper plants after x years will be given by the exponential function:
where 40 is the initial number and 2 is the growth factor.
Answer:
(1-0.01p)/n
Step-by-step explanation:
Mathematically;
Percentage of student playing at least one sport = 100% - Percentage of students playing no sport
Mathematically, that would be;
Percentage playing no sport = 100% - p%
So, to find this in n 7th graders
we have;
(100-p)/100 * n
= 100-P/100n = 1/n - P/100n
= 1/n - 0.01p/n
= (1-0.01p)/n
Let's solve your equation step-by-step
6v^2+v=40
step 1: subtract 40 from both sides
6v^2+v-40=0
6v^2+v-40=0
Step 2: factor left side of equation
(3v+8)(2v-5)=0
step 3: set factors eqyal to 0
3v+8=0 or 2v-5=0
Answer is v= -8/3 or v= 5/2
The answer would be D on question 2.
