Answer:
-1
Step-by-step explanation:
A-(b+c)
Let a=2 b=-5 c=8
2 - (-5+8)
2 - (3)
2-3
-1
The work may be calcualted as the differential of potencial energy or as the product of the force x the distance. The result is the same.
T = weight x height
T = 290 pound * 28 feet = 8120 foot-pound
Answer:
115 cm^2
Step-by-step explanation:
Answer:
C) -5/12
Step-by-step explanation:
To find the slope of a line with given points, you divide the difference of y-coordinates by the difference of the x-coordinates of those same 2 points.
x's:-9-3=-12
y's:-1-(-6)=5
Then, you put the answer of the y's in the numerator, and x's in the denominator, giving you 5/-12, but you can't have a negative in the denominator, moving it up to become -5/12 as the slope.
Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
