While on a road trip, Steve drove 300 miles in 5 hours. After stopping for gas, he drove an additional 120 miles in 2 hours. Doe
s this situation represent a direct variation? If so, what are the independent and dependent variables? A.
Yes, this is direct variation. Miles driven is the independent variable, and time is the dependent variable.
B.
Yes, this is direct variation. Time is the independent variable, and miles driven is the dependent variable.
C.
Yes, this is direct variation. However, because Steve stopped, the variables cannot be determined.
D.
This is not a direct variation because the data would not go through the origin.
B. Yes, this is direct variation. Time is the independent variable, and miles driven is the dependent variable.
Step-by-step explanation:
In a direct variation, when the independent variable increase the dependent variable also increases. In this case, the independent variable is the time (time is always independent) and the miles driven by Steve is the dependent variable. This means, the miles driven increase as time pass.
<span> A. x²+2 - a polynomial B.(x⁸-2)/(x⁻²+3) rational function C. 7x⁷-2x⁻⁴+3 (It has negative value of exponent, so it cannot be a polynomial.) D.x^x-1 (x is an exponent it cannot be a polynomial)</span>
<span>We know that
there is no universal acceptance meaning of a percentile. When someone told you
that you are in the 80th percentile, the meaning of that is you
have achieved the lowest score that is greater than 80 percent of the score. It is calculated by using the formula <span>R = P/100 x (N + 1)</span></span>
