Answer:

84 mm^2

Step-by-step explanation:

The area of a triangle is

A = 1/2 b *h

The base is 14 and the height is 12

A = 1/2 (14*12)

A = 84 mm ^2

Area of a triangle formula: A = 1/2bh

Solve using the values given in the picture.

A = 1/2(14)(12)

A = 1/2(168)

A = 84

Therefore, the volume of the triangle is 84mm²

Best of Luck!

One term of a geometric sequence is a4=135. The common ratio is r=3. Write an explicit rule for the nth term.
Anni [7]

Answer:

a_{n} = 5 * 3^{n-1}

Step-by-step explanation:

To find the nth term of a geometric sequence, you have the general formula:

a_{1} *r^{n-1}

where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):

135 = a_{1} * 3^{4 - 1}

135 = a_{1} * 3^3

135 = 27a_{1}

a_{1} = 5

Now, we can substitute the first term back in:

a_{n} = 5 * 3^{n-1}
