The circle graph below shows the percentages of water which are used for various
activities in the United States. Which statement about the use of water in the
United States is false?
Use of Water
in the United States
Public
10%
Industry
1190
Power Plant
Industrial use of water is greater than the amount used to cool power plants.
Cooling power plants and agricultural use accounts for more than 75% of water use.
More water is used for agricultural purposes than for any other reason
Water use by the public and industry combined does not surpass that used in agriculture,

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
