A = first battery type
b = second battery type

a + b = 6.5 V
a = ( 6.5 V ) - b

b - a = 2.5 V

b - (6.5 - b) = 2.5
2b - 6.5 = 2.5
2b = 9.0
b = 4.5 V
a = 6.5 - 4.5
a = 2.0 V

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
frozen [14]

Note: Consider we need to find the vertices of the triangle A'B'C'

Given:

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.

Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).

To find:

The vertices of the triangle A'B'C'.

Solution:

If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then

(x,y)\to (y,-x)

Using this rule, we get

A(-3,6)\to A'(6,3)

B(2,9)\to B'(9,-2)

C(1,1)\to C'(1,-1)

Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).

Which equation represent the nth term of the arithmetic sequence?
ICE Princess25 [194]

Answer:

<h2>         D.   aₙ = 5n - 11</h2>

Step-by-step explanation:

The equation of the nth term of the arithmetic sequence is: a_n =a_1+d(n-1)

d = 9 - 4 = 5

a₁ = -6

Therefore:

               a_n =-6+5(n-1)\\\\a_n =-6+5n-5\\\\a_n =5n-11

Dale has a special deck of cards. Each card has a different rational number on it. The cards are 0.25,4/5,2/9,0.48, and 8/11. Ho
STALIN [3.7K]
<span>There are two cards which have a value greater than 1/2. In order to calculate this, you need to look at the numbers. 0.25 equals 1/4, which is not greater than a half. 2/9 would also not be greater than one half. 1/2 is .50, so .48 would also not be greater.</span>

Paige borrows $4000 at the interest rate of 12% per year what is due at the end of 3 years
kherson [118]
12% of 4,000 = 480
4,000 * 3 = 12,000
480 * 3 = 1,440
12,000 + 1,440 = 13,440

So...at the end of 3 years, $13,400 is due.

Hope I helped! Please mark Brainliest if correct; I would greatly appreciate it. :)
