Answer:
b. -36/77
Step-by-step explanation:
As 0 < x < 
/2 => tan x > 0
As 0< y < /2 => tan y > 0
We have the formula:
As tan x = 1/(cotx) => 
As tan x > 0 => tan x = 8/15
As tan y > 0 => tan y = 4/3
As tan (x-y)= 
Each angle is 90 degrees because 90 times 3 is 270.
Answer:
it should -1 because you have to evaluate the number
I suppose you thought the following:
A) f(x) = 100^(x-5) - 1
B) f(x) = 3^(x-4) - 2
C) f(x) = 7^(x-1) + 1
D) f(x) = 8^(x+1) - 3
In that case the correct answers are A), B) and D)
Good luck!!!
Answer:
d. 194481
Step-by-step explanation:
We solve this question using exponential growth rate formula
This is given as:
y = a(1 + r) ^t
Where y = Amount after time t
a = Initial amount = 160000
r = growth or increase rate = 5% = 0.05
t = time in years = 4
y = 160000(1 + 0.05)⁴
y = 160000(1.05)⁴
y = 194481
Therefore, the number of cows needed after 4 years to fulfill the requirement of the milk is 194481
