Jenny borrowed $500 for five years at 4 percent interest, compounded annually. What is the total amount she will have paid when
Sladkaya [172]
The total amount due in the future (F) for the current loan (P) with compound interest (i) is calculated through the equation,
                                        F = P x (1 + i)^n
where n is the number of years. Substitute to the equation, the values given above,
                                        F = ($500) x (1 + 0.04)^5 = $608.326
Thus, Jenny would pay approximately $608.326.

Positive angles located in the fourth quadrant may be described as___.
gladu [14]

Answer:

Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360 .</u>

The option is

4. 270≤Ф≤360

Step-by-step explanation:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

For Example.

Quadrant I    - 0 to 90°

Quadrant II   - 90° to 180°

Quadrant III  - 180° to 270°

Quadrant IV - 270° to 360° ( 4. 270≤Ф≤360  )

Hence,Positive angles located in the fourth quadrant may be described as<u> 270≤Ф≤360 .</u>

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV  -          0° to -90°

Quadrant III   -      - 90° to -180°

Quadrant II    -      -180° to -270°

Quadrant I     -      -270° to -360°

Help please :) im not too good at math aha
DIA [1.3K]

Answer:

x = 3 and y = 2

Step-by-step explanation:

For the triangles to be congruent.

The hypotenuse and a leg of one triangle and the hypotenuse and a corresponding leg of the other triangle must be congruent, that is

x = y + 1 → (1) congruent legs

3y = x + 3 → (2) congruent hypotenuse

Substitute x = y + 1 into (2)

3y = y + 1 + 3, that is

3y = y + 4 ( subtract y from both sides )

2y = 4 ( divide both sides by 2 )

y = 2

Substitute y = 2 into (1)

x = 2 + 1 = 3
