32/40 is the fraction to 32:40 and if u simplify it, it would be 4/5
General term of a geometric sequence is
a(n)=a(1)×r^(n-1)
a1=5
a2=5×6=30
a3=5×6²=180
a4=5×6³=1080
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
Step-by-step explanation:
the area of a parallelogram is
baseline × height
which is in our case
9 × 7 = 63 m²
Answer:
I am sure it's $8
Step by step explanation:
Total money spent= $82
Cost of dictionary= $26
Cost of 7 novels = $82 - $26
= $56
Cost of 1 novel = $56/7
= $8
Therefore, each novel bought by Esme cost $8
