Suppose you measured the diameter of a tree trunk to be 5 cm. the actual diameter can vary by at most 0.4 cm, due to the error in measuring a non-flat surface. write an absolute value inequality for the range of acceptable diameters and solve the inequality.
a. |d − 5| ≤ 0.4; 4.6 ≤ d ≤ 5.4
b. |d + 5| ≤ 0.4; −5.4 ≤ d ≤ −4.6
c. |d + 0.4| ≤ 5; −5.4 ≤ d ≤ 4.6
d. |d − 0.4| ≤ 5; −4.6 ≤ d ≤ 5.4

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
