Select the common ratio and the 4th term of the geometric series: 9, -6,4...

Blababa [14]

The given geometric sequence has the common ratio, r = -2/3, and the value of the 4th term, a₄ = -8/3.

A geometric sequence is a special series where every term is the product of the previous term and a common ratio.

The first term of a geometric sequence is represented as a, the common ratio as r, and the n-th term as aₙ, which is calculated as, aₙ = a.rⁿ⁻¹.

In the question, we are asked to find the common ratio and the 4th term of the geometric sequence, 9, -6, 4, ........

The first term of the sequence, a = 9.

The second term of the sequence, a₂ = -6.

By the formula of the n-th term, aₙ = a.rⁿ⁻¹, we can show that:

a₂ = a.r²⁻¹.

Substituting the values, we get:

-6 = 9(r²⁻¹),

or, r²⁻¹ = -6/9,

or, r = -2/3.

Thus, the common ratio of the given geometric sequence is -2/3.

The 4th term can be calculated using the formula of the n-th term, aₙ = a.rⁿ⁻¹ as:

a₄ = a.r⁴⁻¹ = a.r³.

Substituting the values, we get:

a₄ = 9(-2/3)³,

or, a₄ = 9.(-8/27),

or, a₄ = -8/3.

Thus, the 4th term of the given geometric sequence is -8/3.

If the legs of a right triangle are 6 cm and 5 cm find the area of the triangle

Ilia_Sergeevich [38]

Answer: 15 cm²

Step-by-step explanation: To find the area of a triangle, start with the formula for the area of a triangle which is shown below.

$Area = \frac{1}{2}bh$

In this triangle, the base is 6 centimeters and the height is 5 centimeters. Now, plugging into the formula, we have $(\frac{1}{2})(6 cm)(5 cm)$ .

Now, it doesn't matter which order we multiply.

So we can begin by multiplying 1/2 times 6 cm and notice that the 2 in 1/2 and the 6 cross cancel to 1 and 3. So we're left with 3 cm.

Now, (3 cm)(5cm) is 15 cm².

So the area of the triangle is 15 cm².
