Answer:
The work done in stretching the spring is 8 lb.ft
Step-by-step explanation:
Given;
Applied force, F = 192 lb
extension of the spring, x = 3 ft
Determine the spring constant from the applied force and extension;
[tex]k = \frac{F}{x} \\\\k = \frac{192 \ lb}{3 \ ft} \\\\k = 64 \ lb/ft[/tex]
When the spring is stretched 6 inches beyond its natural length, the work done is calculated as follows;
x = 6 inches = 0.5 ft
[tex]W = \frac{1}{2} kx^2\\\\W = \frac{1}{2} (64 \ lb/ft)(0.5 \ ft)^2\\\\W = 8 \ lb.ft[/tex]
Therefore, the work done in stretching the spring is 8 lb.ft

I don't really understand exponents well I was wondering if I could get some help on this plz
Ok so do 9 times itself 5 times so basically its this:
9*9*9*9*9
Next do the same but 3 times:
9*9*9
Exponents are not this:
9*3
But this:
9*9*9
Your answer:
59049/729
Another way to say it:
59049 over 729
There is your answer hope this helps
Answer:
9^2 (9 to the power of 2)
Step-by-step explanation:
Ok, this is how you find exponents:
Well, exponents are really just abbreviated multiplication, so to find the numerical value of 9^5 and 9^3, you need to multiply 9 by itself 5 times and 3 times, then divide.
9*9*9*9*9= 59049
9*9*9= 729
Then you divide: 59049/729= 81.
But the question asks to rewrite the answer using a single positive exponent, so now we simplify 81 into an exponent.
The square root of 81= 9
9*9=81
81 as an exponent= 9^2 (or 9 multiplied 2 times)
Another simple trick for solving exponents is to subtract the exponents:
9^5-9^3= 9^2 (5-3=2)
I hope this answer was helpful!

Kelly sells 62 shares of stock she owns for a total of $433. If the stock was in two different companies, one selling at $6.50 a share and the other at $7.25 a share how many of each did she sell?
Answer:
Step-by-step explanation:
x^2+6x+9=16 solve by completing the square
First move the 9 to the right side by subtracting 9 from both sides.
So we have x² + 6x ___ = 7 ___.
Notice that I created a space on each side of the equation.
The space is what we need to complete the square.
The number that goes in the spaces comes from half the coefficient of the
middle term squared, which in this case is half of 6, or 3, squared, which is 9.
So we add 9 to both sides of the equation.
Once we have completed the square, out trinomial will always factor as a binomial squared, and the number that goes inside the binomial will always be half the coefficient of the middle term of the trinomial.
So we have (x + 3)² = 16.
Now square root both sides to get x + 3 = ± 4
So x + 3 = 4 or x + 3 = -4.
Solving each equation from here, we get x = 1 or x = -7.
So our solution set is {1, -7}.

Answer:
(b) 60°
Step-by-step explanation:
The sum of angles in a pentagon is 540°, so you have ...
90° +90° +150° +x +150° = 540°
x = 540° -480°
x = 60°

Solve for the value of W
Answer:
8°
Step-by-step explanation:
5w + 1° + 7w - 7° + 90° = 180° { being linear pair }
12w = 180° - 84°
12w = 96°
w = 96° / 12
w = 8°
Hope it helps :)
Answer:
5w+1+90+7w-7=180(linear pair)
12w=180-84
w=96/12=8
