Step-by-step explanation:
Hypotenuse of a right angle triangle from pythagoras theorem is given by
h²=b²+a²
Making h the subject
h=√(b²+a²)
Where h is hypotenuse, b is base and a is the other side of a triangle
10²+24²=676
√676=26 units
72²+21²=5625
√5625=75 units
12²+35²=1369
√1369=37 units
18²+80²=6724
√6724=82 units
105²+100²=21025
√21025=145 units
16²+30²=1156
√1156=34 units
Answer: 2
Step-by-step explanation:
So you distribute the -6 to the n and -1
Resulting info d(n)= 8-6n+6
Combine the 8 and 6. Getting 14
Add 6n in both sides getting
7n=14
Divide by 7
N=2
A. Expanding the given expression, you have
balance = 75r^2 +150r +75
B. For r=0.10, the balance after 2 years is 75*1.1^2 = 90.75
C. The difference between $120 and 90.75 is $29.25. You need $29.25 more to buy the bicycle.
