From the given the function, <span>y(t)=−t²+14t−40; the graph will be as shown below:
From the graph, it is evident that between the intervals 6</span>≤t≤8<span>:
The value of our function decreases over the given interval. Hence the answer is:
</span><span>a. The value of y(t) increases over the interval 6≤t≤7
</span>
Notes before we start:
Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.
Explanation:
Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.
15 * 40 * 2 = $1,200
Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.
Answer:
Job B pays better.
Best of Luck!
Area=1/2*base*height
given that ABC is right angled triangle, the height will be given by:
tan theta=opposite/adjacent
tan 60=h/6
h=6tan60
=10.4
thus the area will be:
A=1/2x6x10.4
=31.2 cm^2
