Answer:
1/2
Step-by-step explanation:
there are two results since there is heads and tails
Option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.
<h3>What is the slope?</h3>
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

We have a function:
v(t) = 352 − 48t
The above function represents the speed of a plane that is landing in the sky.
The function is a linear function.
On comparing with:
y = mx + c
v(t) = -48t + 352
m = -48
-48 is the slope and it representing velocity decreases at rate of 48 miles per hour as the time increases.
Thus, option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.

Answer:
The first three terms is 64, 32, 16
Step-by-step explanation:
Given
Number of participants = 64
Decrement = 1/2
Required
Find the first three terms
To calculate the first three terms, we make use of the following formula;
Current Term = Previous Term - 1/2 * Previous Term
The first term = Initial number of participants
First Term = 64
Second Term = First Term - 1/2 * First Term
Second Term = 64 - 1/2 * 64
Second Term = 64 - 32
Second Term = 32
Third Term = Second Term - 1/2 * Second Term
Third Term = 32 - 1/2 * 32
Third Term = 32 - 16
Third Term = 16
Hence, the first three terms is 64, 32, 16
