Answer: y(k) = 75.32*k + 1986
Steps:
Orbital period of the Halley's comet is 75.32 years. Set up a function with variable k denoting the "k-th" time the comet is seen again since last sighting in 1986:
y(k) = 75.32*k + 1986
The function value is the year (including decimal fraction) when the comet will be seen for the k-the time since 1986.
The largest number of caps Laura can purchase is 162.
x(number of caps)6 + 25 = c (cost)
(162)6 + 25 = 997
972 + 25 = 997

Answer:
Yes
Step-by-step explanation:
The multiplicative rate of change of the function will be 0.5. Then the correct option is C.
<h3>What is an exponent?</h3>
Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as
y = a(b)ˣ
The missing table is attached below.
For x = 2, y will be 0.125
0.125 = ab² ...1
For x = 3, y will be 0.0625
0.0625 = ab³ ...2
Divide equation 2 by equation 1, we have
b = 0.0625 / 0.125
b = 0.5
Then the correct option is C.
