Answer:
Charles is incorrect
Step-by-step explanation:
Lupe bought 8 pounds of pretzels for $18, meaning that she bought them at a unit rate of $2.25 per pound. Charles bough 6 pounds of pretzels for $15, meaning he bought them at a unit rate of $2.50 per pound. Even though Charles paid less, he didn't get the better deal because he paid more per pound than Lupe did.
The correct answer is D. P 720:)
Answer:
<h2>11</h2>
Step-by-step explanation:
Given h(t) = t²+t+ 12 and k(t) = √t-1, we are to find k(k.h)(10)
k{h(t)} = k{ t²+t+ 12}
Since k(t)= √t-1, we will replace the variable t in the function with t²+t+ 12
k(h(t)) = √{(t²+t+ 12)-1}
k(h(t)) = √t²+t+12-1
k(h(t)) = √t²+t+11
Substituting t = 10 into the resulting function;
k(h(10)) = √(10)²+(10)+11
k(h(10)) = √100+10+11
k(h(10)) = √121
<em>k(h(10))= 11</em>
<em></em>
<em>hence the value of (k compose h) (10) is 11</em>
