Find the sum of the first 9 terms of the sequence. Show all work for full credit.
Kamila [148]
We can see the sequence goes by decreasing 9 on each number

so the numbers are

2, -7, -16, -25, -34, -43, -52, -61, -70

so adding all these numbers we get

2-7-16-25-34-43-52-61-70

= -306


hope this helped

Assume the 72-gon is a regular polygon. The measure of one interior angle is how many
Greeley [361]

9514 1404 393

Answer:

  • interior: 175°
  • exterior: 5°

Step-by-step explanation:

The sum of exterior angles is 360°, so the exterior angle can be easiest to find first.

  exterior angle = 360°/72 = 5°

The interior angle is the supplement of this.

  interior angle = 180° -5° = 175°

The measure of one interior angle is 175°; one exterior angle is 5°.

Using scalar multiplication, find 5u if u= &lt;2, 4&gt;.
kicyunya [14]

Using scalar multiplication, it is found that 5u = <10,20>.

<h3>What is scalar multiplication?</h3>
  • It is when a vector is multiplied by a constant, and it means that each term of the vector is multiplied by the constant.

In this problem, the vector is:

u = <2,4>

Since each term is multiplied by 5:

5u = <5 x 2, 5 x 4> = <10,20>.
