The first term of an arithmetic sequence is 5, and the tenth term is 13. Find the common difference
RideAnS [48]

Common difference d when The first term of an arithmetic sequence is 5, and the tenth term is 13 is d=\frac{8}{9}

Step-by-step explanation:

The first term a₁ = 5

The tenth term a₁₀ = 13

Find Common difference d=?

The formula used for arithmetic sequence is:

a_{n}=a_{1}+(n-1)d

where aₙ = nth term

a₁= 1st term

d= common difference

Finding d:

a_{10}=a_{1}+(n-1)d\\Putting\,\,values\,\,a_{10}=13, a_{1}=5 and n=10\\13=5+(10-1)d\\13-5=9d\\8=9d\\d=\frac{8}{9}

So, Common difference d when The first term of an arithmetic sequence is 5, and the tenth term is 13 is d=\frac{8}{9}

What is the missing constant term in the perfect square that starts with X^2 - 8x
xenn [34]

Answer:

16

Step-by-step explanation:

Perfect square in the quadratic from ax² + bx + c

You know an equation is perfect when:

2√(ax²)√(c) = bx

Substitute x² for ax² and 8x for bx. Then isolate c by doing the reverse operations.

2√(ax²)√(c) = bx

2√(x²)√(c) = 8x

2x√c = 8x   Divide both sides by 2x

√c = 4    Square both sides to isolate c.

c = 16

The missing constant term is 16.

Check answer:

x² - 8x + 16

(x - 4)²

= (x - 4)(x - 4)

= x² - 4x - 4x + 16

= x² - 8x + 16
