Df/dy=(1350-750)/(2010-2000)
df/dy=60
f(y)=750+60(y-2000) or neatened up a bit...
f(y)=60y-119250 (note: y is the actual year, ie 2005, not year like 2 years from start)
We know that
Law of sines established
a/sin A=b/sin B=c/sin C
then
a/sin A=c/sin C------------> a=c*sin A/sin C---------> a=6*sin 19/sin 102
a=1.91 units <span>≈2 units
A+B+C=180</span>°----------> B=180-(A+C)-----> B=1180-(19+102)
B=59°
a/sin A=b/sin B-----------> b=a*sin B/sin A----->2*sin 59/sin 19
b=5.27 units <span>≈5.3 units</span>
the answer is the option
B = 59°, a ≈ 2, b ≈ 5.3
Answer:
$122.89
Step-by-step explanation:
The two number you have in this equation are 108.75 and 13% (or .13)
first you want to multiply 108.75 to .13
108.75 * .13 = 14.1375
Now, you add 14.1375 to 180.75 and round to the nearest hundredth
180.75+ 14.1375=122.8875
$122.89
The positive trend among the homework scores and the test scores would reveal that if a student does well in homework, he is likely to do well in exams. This can be explained in the sense that the homework will serve as the practice for the student before finally taking the exam.
