(4,-2)
Step-by-step explanation:
The product of (2j + 7)(2j - 7) is .
Given
The product mentally;
<h3>What is multiplication?</h3>
Multiplication is the process of calculating the product of two or more numbers.
The multiplication of numbers say, ‘a’ and ‘b’, is stated as ‘a’ multiplied by ‘b’.
The product of (2j + 7)(2j - 7) is given by
Hence, the product of (2j + 7)(2j - 7) is .

From your earlier questions, we found
so the wave has amplitude √29. The weight's maximum negative position from equilibrium is then -√29, so you are solving for <em>t</em> in the given interval for which
Divide both sides by √29:
Take the inverse sine of both sides, noting that we get two possible solution sets because we have
and the sine wave has period 2π, so .
OR
where <em>n</em> is any integer.
Now solve for <em>t</em> :
OR
We get solutions between 0 and 0.5 when <em>n</em> = 0 of <em>t </em>≈ 0.196946 and <em>t</em> ≈ 0.363613.
180 ÷ 45 is 4
so
4 time 20 is 80
Answer: 80
