Answer:
False
Step-by-step explanation:
Solving the equation
3x² - 5x - 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 2 = - 6 and sum = - 5
The factors are - 6 and + 1
Use these factors to split the x- term
3x² - 6x + x - 2 = 0 ( factor the first/second and third/fourth terms )
3x(x - 2) + 1(x - 2) = 0 ← factor out (x - 2) from each term
(x - 2)(3x + 1) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
3x + 1 = 0 ⇒ 3x = - 1 ⇒ x = -
Solutions are x = 2 and x = -

Answer:
always try to draw a diagram first
Step-by-step explanation:
Jana ran The first 3.5 miles in 1/3 of an hour. remember the problem tells us that we want our answer in miles per hour or mph. so we have to set up our problem so that our units match in the end. The diagram above shows 3.5 mi over 1/3 hour. so we must divide 3.5 miles by 1/3 hour

Answer:
Step-by-step explanation:
From the question we are told that
Arc of 30 cm
10% reduction after each swing
Generally sum of geometric sequence is given by the equation
Mathematically solving for total distance traveled we have
Therefore the total distance traveled by the pendulum after 5 swings
