Answer:
sqrt(144) = ±12
Step-by-step explanation:
sqrt(144)
What number, when multiplied by itself, gives 144
12*12 = 144
-12*-12 = 144
sqrt(144) = ±12
Answer:
61.8 and 118.2
Step-by-step explanation:
Let's call one angle A and the other B. Supplementary angles add to 180, so A+B=180. If B=A+56.4, then we can rewrite the equation in terms of A, or A+(A+56.4)=180 or 2A+56.4=180. To solve, first subtract 56.4 from each side and then divide by 2 to get A=61.8. Since the angle is supplementary, all we need to do to find B is subtract A (61.8) from 180 to get B=118.2.
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.
