Answer:
give me a minute to find the answer
Step-by-step explanation:
To find the average change per hour, divide the total change by the total time:
-9.9 inches / 2.25 hours = -4.4 inches per hour.
The solutions to the given quadratic equation {49n² - 301n + 42 = 0 } are 1/7 and 6.
<h3>What are the solutions to the given quadratic equation?</h3>
Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is expressed as;
ax² + bx + c = 0
Where x is the unknown
To solve for x, we use the quadratic formula
x = (-b±√(b² - 4ac)) / (2a)
Given the equation in the question;
49n² - 301n + 42 = 0
Compared to the standard form of quadratic equation { ax² + bx + c = 0 }
We plug in these values into the quadratic formula.
x = (-b±√(b² - 4ac)) / (2a)
x = (-(-301) ±√((-301)² - 4 × 49 × 42 )) / (2 × 49)
x = ( 301 ±√( 90601 - 8232 )) / 98
x = ( 301 ±√( 82369 )) / 98
x = ( 301 ± 287) / 98
x = (301 - 287)/98, (301 + 287)/98
x = 14/98, 588/98
x = 1/7, 6
Therefore, the solutions to the given quadratic equation {49n² - 301n + 42 = 0 } are 1/7 and 6.

Hi there!
Use th' following formula
To find the distance between each pair of pts. :-
According to th' question :-
♦ (-2, -2) (-2, 10) :--
=
= 12
Therefore,
distance between the following pts. is 12 units.
♦ (-5.3, -2.2) (-5.3, -8.7) :--
=
= 6.5
Therefore,
distance between th' following pts. is 6.5 units.
