NO!
Prove by contradiction. First, define the the following terms:
odd function: f(-x) = -f(x)] and domain: all values of x
Proof: Suppose there f(-x) = -f(x) such that x is a negative integer, then f(-x) is a positive number <em>(-(-x) = +x)</em> and -f(x) is a negative number <em>(negative of a positive number is a negative number). </em>Since a positive number cannot equal a negative number, then this is not possible.
Answer: No
Answer:
B) 25% of her students are in chemistry.
Step-by-step explanation:
There were 0.1, or 10%, of freshmen in chemistry. There were 0.25, or 25%, of sophomores in chemistry. This is a total of 0.1+0.25 = 0.35, or 35%.
This is not 25%.
Complete question :
Each state imposes its own excise tax on gasoline. Suppose, for example, that the state of Massachusetts imposes a state gasoline tax of $0.26 per gallon. Suppose further that an average of 1,022,000 gallons of gasoline per day were sold in Massachusetts in 2010. The average revenue from gasoline tax in 2010 is approximately?
Answer:
$265,720
Step-by-step explanation:
Given that:
State gasoline tax = $0.26 per gallon
Average number of gasoline sold per day = 1,022,000 gallons
. From the availabke information given :
Revenue generated = gasoline tax per gallon multiplied by the average number of gallons sold
= $0.26 * 1,022,000
= $265,720
Answer
<span>A. Rectangle
</span><span>D. Parallelogram
Explanation
The four choices are all quadrilaterals with with at least a pair of parallel sides.
A rectangle, a square, and a rhombus have opposite sides been parallel.
For a square and a rhombus, the diagonals are perpendicular.
The diagonals of a rectangle and a parallelograms are not perpendicular.
