Answer:
The degree is 7 and the leading coefficient is -21.
Step-by-step explanation:
The degree of an equation is found using the highest exponent on the variable in the equation.
-12-8x^2+5x-21x^7 has the term x^7 so its degree is 7
The leading coefficient is the coefficient of the term with the highest degree. The coefficient of x^7 is -21.
Ken's distance is: d(t)=1.7t
Ken's shadow is:
(14-6)/d(t)=14/s
8/d(t)=14/s
s=14d(t)/8
s=1.75d(t) and using the value for d(t) we have:
s=1.75(1.7t)
s=2.975t and if you want it in terms of d, d=1.7t, t=d/1.7 so
s=2.975(d/1.7)
s=1.75d
Answer:
15.40/3.5=$4.40 dollars a pound
7.65/1.8=$4.25 dollars a pound
Step-by-step explanation:
divide to get the unit price
so 7.65/1.8=$4.25 dollars a pound is the cheaper unit as well.
