Answer:
1/5 . 950
This is cause 20% =20/100 and when reduced it is 1/5
Tan(theta) = 5/4
sin(theta)/cos (theta)=5/4
cos(theta)=4sin(theta)/5
sin²(theta)+cos²(theta)=1
sin²(theta)+16sin²(iheta)/25=1 /*25
25 sin²(theta)+16 sin²(theta)=25
sin²(theta)=25/41 /√
sin(theta)=
cos(theta)=
cot(theta)=
csc(theta)=1/sin(theta)=
sec(theta)=1/cos(theta)=
Answer:
Part 1) The exponential function is 
Part 2) 
Step-by-step explanation:
Part 1) Write an exponential function
we know that
The exponential growth function is given by the formula

where
y is the population
x is the number of years
a is the initial population
r is the rate of change
we have

substitute


Part 2) How much will the population be after 16 years?
For x=16 years
substitute the value of x in the exponential function

Answer:
a=1/2
Step-by-step explanation:
From the question, the expression a(8x+7) is equivalent to 4x+3.5
Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5
So, we can write the following to find the value of a

we can write the following
8ax=4x

Hence the value of a is 1/2
