So for this, we can simplify √63 as such:

$\sqrt{63}=\sqrt{7*9}=3\sqrt{7}$

Using the simplified version of √63, we can solve it:

$3\sqrt{7} -3\sqrt{7} =0$

Zero is your final answer.

Solve for x in this equation: 3/4+ |5-x| = 13/4

Rom4ik [11]

Answer:

x = 2.5 or 7.5

Step-by-step explanation:

Subtract 3/4.

|5 -x| = 10/4 = 2.5

This resolves to two equations:

5 -x = 2.5 ⇒ x = 5 -2.5 = 2.5
5 -x = -2.5 ⇒ x = 5 +2.5 = 7.5

The solutions are x = 2.5 or 7.5.

What is the formula for the nth term of the given sequence 100, 20, 4, …

Naily [24]

Answer:

$a_n=100 \left(\dfrac15\right)^{n-1}$

Step-by-step explanation:

General equation of geometric sequence: $a_n=ar^{n-1}$

Given:

a₁ = 100
a₂ = 20
a₃ = 4

$\implies a_1=a=100$

$\implies a_2=100 \cdot r=20$

$\implies a_3=100 \cdot r^2=4$

Common ratio:

$r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15$

Therefore:

$a_n=100 \left(\dfrac15\right)^{n-1}$
