Answer:
this is an arithmetic sequence. The formula to solve it is an = d (n - 1) + c
Step-by-step explanation:
you would plug in the first term in the sequence for d. then you would plug in the common difference for c. And then lastly you would plug in whatever nth term you are trying to get to for n. Then solve.
Answer:
1.)
y= (15 x 3) - 40
y= 45-40
y= 41
2.)
y= (2/3 x 21) +20
y= 14+20
y= 34
3.)
y= (3* -2)² +17
y= -6² +17
y= -36 +17
y= -19
SRY I DID NOT ANSWER BEFORE
The length of other leg is 60 units.
Step-by-step explanation:
Given,
Length of one leg = a = 45 units
Length of other leg = b
Length of hypotenuse = c = 75 units
Using pythagoras theorem

Taking square root on both sides

The length of other leg is 60 units.
