F = 1/2kp....multiply both sides by 2, eliminating the 1/2
2F = kp...now divide both sides by p
(2F/p) = k
You can use the method of pythagorean theorem.
a² + b² = c²
or in your case, 14² + 15² = x²
14² = 14 * 14 = 196
15² = 15 * 15 = 225
196 + 225 = 451
√451 = 21.237
or 21.23676058159
*I rounded to the nearest thousands place
Answer:
Step-by-step explanation:
Note that the distance from -5/7 to 6/7 is 6/7 - (-5/7) = 11/7.
So, if you take steps of 1/7 each, there are 10 steps between -5/7 = 11/7.
-4/7, -3/7, -2/7, ..., 5/7
Answer:
x=3 or x= 1/3
Step-by-step explanation:
Let the number = x
The reciprocal of the number = 1/x
According to the given statement:
x+1/x=10/3
x²+1/x=10/3
3(x²+1)=10x
3x²+3=10x
Move 10x to the L.H.S
3x²-10x+3=0
Break the middle term:
3x²-9x-x+3=0
3x(x-3)-1(x-3)=0
(x-3)(3x-1)=0
x-3=0 , 3x-1=0
x=0+3 , 3x=0+1
x=3 , 3x=1
x=3 ,x = 1/3
So x=3 or x= 1/3 ....
Answer:
Your answer is 539.93
Step-by-step explanation:
A = pi*r²
A = pi* 13²
A = pi*169
A = 539.93
