1 find the hcf of the number by means of prime number a 52 and 78 b95 and 120

am suppose to use a square root please help me answer

a. Get the prime factorizations of 52 and 78:

52 = 2² • 13

78 = 2 • 3 • 13

Then the HCF/GCD of 52 and 78 is 2 • 13 = 26, because both 2 and 13 are common divisors of 52 and 78.

b. Do the same thing for 95 and 120:

95 = 5 • 19

120 = 2³ • 3 • 5

Then the HCF is 5.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8
