Answer:
we are looking for F
but in the question it stated that f(n) and at the end it also stated that f(1) so n=1
Step-by-step explanation:
we are using BODMAS
f(n-1)+1
f(1-1)+1=0+1
f=1
Answer:
Company B is the better deal. Diego will save $31.5.
Step-by-step explanation:
First, find the area of the rectangle: 45*30=1350 sq.ft.
Next, find out how much it will cost for Company A: $3.9 for 2 x 5 ft (10 sq.ft)
Divide 1350 by 10 to see how many of their sod rolls will fit into his yard=135.
Multiply $3.9 by 135=526.5$
Do the same with Company B: $150 for 450 sq.ft plus $45 delivery.
Dived 1350 by 450 to see how many rolls= 3
Multiply $150 by 3= $450, then add $45= $495
Subtract Company B's $495 from Company A's $526.5= $31.5 <-how much Diego saved.
Answer is 16 because 16/4 = 4 + -12 = -8
Answer:
Option 2
Step-by-step explanation:
In ΔABC,
AD is a median and point M is the point of concurrence of all medians.
Therefore, point M is a centroid of the triangle.
And M will divide line AD in the ratio of 1 : 2 (Ratio of AM : MD)
Since, length of MD = 2 cm
Therefore, length of AM = 4 cm
Total length of AD = AM + MD
= 2 + 4
= 6
Option 2 will be the answer.
