The answer is c b and should be d
Its faster in adding isn't always right when you are multiplying numbers
To model this situation, we are going to use the exponential function:
where
is the initial number of cars
is the growing rate in decimal form
is number of tames the growing rate is increasing per year
is the time in years
To convert the growing rate to decimal form, we are going to divide the rate by 100%
Since the growing rate is increasing quarterly,
. We also know that the initial number of cars is 920, so
. Lets replace all those values in our function:
We can conclude that:
Rate ---------> The quarterly rate of growth is 0.03 or 3%
Exponent --------> The compound periods multiplied by the number of years is 4t
Coefficient--------> The initial number of cars serviced is 920
Base------> The growth factor is represented by 1.03
Answer: 7
Step-by-step explanation:
First set up your equation 40+21x=187
Subtract 40 from each side 187-40=147 40-40=0 Bring down your 21x than divide 147 by 21. 147÷21=7
Answer:
C^2=A^2+B^2
=11.87^2+18^2
= 140.90+324
= 464.9
C= square root of 464.9
= 21.56, the hypotenuse
Siny= 18/21.56
= 0.835
y =Sin^-1(0.835)
=56.62
Sinx= 11.87/21.56
=0.551
x =Sin^-1(0.551)
= 33.44
thats one way, i chose a longer way cuz i think its better to go through the steps
Step-by-step explanation:
Sin=opp/hyp
Cos=adj/hyp
Tan=opp/adj
you can use these to solve it other ways
