Answer:
1) a) yes
b) no
c) a² - 39
(a)² - (sqrt(39))²
(a - sqrt(39))(a + sqrt(39))
This quadratic can be split into real factors, but not rational
sqrt(39) is a real number, but not rational
Answer:
The cost of insurance change 29,6% between 2015 and 2018.
Step-by-step explanation:
We can start by defining C as the cost of insurance in 2015.
Then, we know it rose 13% between 2015 and 2016:
It then dropped by 2% between 2016 and 2017:
And then it increases by 17% between 2017 and 2018:
We can conclude the cost of insurance change 29,6% between 2015 and 2018.
Answer:
---- critical point
local minima
Step-by-step explanation:
Given
Required
Determine the critical point
Differentiate w.r.t x
Differentiate w.r.t y
Equate both to 0
Divide by 2
----- in both equations
Hence:
The critical point is:
Solving (b):
We have:
This is represented as:
Calculate the determinant
The critical point is at local minima
700/10=70
140/70=2
A heart beats 70 beats a minute
It takes 2 min to beat 140 times
I’m pretty sure it’s 11 cause u divide 374 by 34 to get 11 which to get area u of length times width which is 11
