Answer:
the exact form is
but the decimal form is 12.124 :)))
Step-by-step explanation:
Answer:
Original equation:
y = a sin(b(θ -c)) + d
a = vertical dilation (stretch) of the amplitude
b = horizontal compression (shrink) of the period
c = horizontal shift (left/right)
d = vertical shift (up/down)
Your function is:
y = 3 sin(3θ + π) - 2
First, put it into the general from by factoring out the three in the argument of the sine:
y = 3 sin(3(θ + π/3)) - 2
a = vertical (amplitude) dilation = 3
b = horizontal (period) compression = 2π/period = 3
c = horizontal shift = π/3 to the left
d = vertical shift = -2

Step-by-step explanation:
<u>FACTS TO KNOW BEFORE SOLVING :-</u>
<em>Quadratic Formula :-</em>
Lets say , there's an equation ax² + bx + c.

<u>SOLUTION :-</u>
According to the question ,
- a (Coefficient of x²) = 4
By using quadratic formula ,


are the factors of 4x² + x - 13.
The equation is y = 250(0.89)^x and the decay rate is 11%.
<h3>How to calculate the values?</h3>
The initial value will be:
= 250(0.89)^x
= 250(0.89^0)
= 250
The decay rate will be:
= 1 - 0.89
= 0.11
= 11%
In conclusion, the equation is y = 250(0.89)^x and the decay rate is 11%.
