It is 14 because if you have -1/2x + 1 = -x + 8 you would combine the multiplied terms into a single fraction then subtract the one from both sides simplify till you get -x/2 = -x + 7 then you will add like terms so the x’s then you multiply all terms by two like 2(-x/2)= 2•7 then you can get 14.

3 ft is less than 21 ft
(if you ment 21 inches 3ft=36 inches so if you ment that 3 ft would be larger in that case)
Answer:
-14°
Step-by-step explanation:
So we start at -34°. It rose 7°, so the temperature becomes -27°. It rose again by 17° so now it's -10°. It fell by 4° so by Tuesday night, the temperature is -14°
<u>Answer-</u>
<em>After 76 swings</em><em> the angle through which it swings less than 1°</em>
<u>Solution-</u>
From the question,
Angle of the first of swing = 30° and then each succeeding oscillation is through 95% of the angle of the one before it.
So the angle of the second swing = 
Then the angle of third swing = 
So, this follows a Geometric Progression.

a = The initial term = 30
r = Common ratio = 
As we have to find the number swings when the angle swept by the pendulum is less than 1°.
So we have the nth number is the series as 1, applying the formula

Putting the values,


Taking logarithm of both sides,







Therefore, after 76 swings the angle through which it swings less than 1°
