Answer:
s = 4·3^t
Step-by-step explanation:
After the first term, each term in the sequence is 3 times the previous one. This is a description of a geometric sequence. Here, the first term is 4, so the general term is ...
an = 4·3^n . . . . for n counting from 0
We can name the function "s" for "speed" and use "t" for the time in seconds. Then the equation is ...
s = 4·3^t
Answer:
The solution of y² - 1 = 15 is +4 and -4
Step-by-step explanation:
Given
y² - 1 = 15
Our solution goes thus;
Make y² the subject of formula
y² = 15 + 1
Add 15 to 1
y² = 16
Take square roots of both sides
√y² = √16
y = √16
Note that the square root of 16 is either +4 or -4 because +4 * +4 = 16 and -4 * -4 = 16; So, we replace √16 with ±4 which means + or -4
y = ±4
y = +4 and -4
Hence, the solution of y² - 1 = 15 is +4 and -4
