Answer:

aₙ = 0.2(-0.3)⁽ⁿ⁻¹⁾

Step-by-step explanation:

The geometric sequence with the first term a, a common ratio r has the nth term given as

Tₙ = arⁿ⁻¹

where Tₙ is the nth term

From the given sequence

a = 0.2

r = -0.06/0.2

= -0.3

Hence the nth term

= 0.2 * -0.3ⁿ⁻¹

The right option is E

The area of a triangle is 30 square centimeters and its base is 10 cm. What is the height in cm of the triangle
Vesnalui [34]

Answer:

The height of the triangle is 6 cm.

Step-by-step explanation:

----------------------------------------

The formula for solving the area of a triangle is  A=\frac{1}{2}bh where b stands for base and h stands for height.

Let's substitute 30 cm^2 for the area and 10 for the base.

30=\frac{1}{2} (10)h

-------------------->>>>

Now, let's solve to find the height.

30=\frac{1}{2}(10)h

Multiply \frac{1}{2} times 10

30=5h

Divide both sides by 5.

6=h

-----------------------------------------

Hope this is helpful.

Find the determinant of the following matrix. [1 -2] [3 4]​
Andrew [12]

Answer:

10

Step-by-step explanation:

[1 -2]

[3 4]

We can obtain the determinant of the above matrix by doing the following:

Determinant =(1 × 4) – (3 × –2)

Determinant = 4 – – 6

Determinant = 4 + 6

Determinant = 10

Thus, the determinant of the above matrix is 10
