What is the distance between (-2 1/2,-3) and (1,-3
satela [25.4K]

Answer:

3\frac{1}{2}\ units

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

(-2\frac{1}{2},-3)\ and\ (1,-3)

Convert mixed number to an improper fraction

2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}

so

we have

(-\frac{5}{2},-3)\ and\ (1,-3)

substitute the values in the formula

d=\sqrt{(-3+3)^{2}+(1+\frac{5}{2})^{2}}

d=\sqrt{(0)^{2}+(\frac{7}{2})^{2}}

d=\frac{7}{2}\ units

Convert to mixed number

\frac{7}{2}\ units=\frac{6}{2}+\frac{1}{2}=3\frac{1}{2}\ units

Determine the nth term rule and find the 45th term for the arithmetic sequence with a10=1 and d-6
kari74 [83]

Answer: -209

Step-by-step explanation:

Formula for arithmetic progression

= a + (n - 1)d

Since a10 = 1 and d = -6

a10 = a + 9d

a + 9(-6) = 1

a - 54 = 1

a = 1 + 54

a = 55

Therefore, 45th term = a + (n - 1)d

= a + (45 - 1)d

= a + 44d

= 55 + 44(-6)

= 55 - 264

= -209
