If you get $2,000 for graduation gifts and invest it in an account that earns 1.5% interest
Eduardwww [97]

Answer:

It is VERY important to use the attached formula.

Years = ln (Total / Principal) / rate

Years = ln (6,000 / 2,000) / rate

Years = ln (3) / rate

Years = 1.0986122887 / .015

Years = 73.24 years

This takes a LONG time because the interest rate is extremely low.

if trapezoid ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A’lie
maria [59]

Answer:

<em>Answer: (second option) (-4,1)</em>

Step-by-step explanation:

<u>Transformations of Points and Shapes</u>

The image shows a trapezoid ABCD where point A has coordinates (-4,1).

The following transformations are performed:

Reflection over the y-axis: If a point (x,y) is reflected over the y-axis, it becomes (-x,y). Thus point A becomes A'=(4,1)

Reflection over the x-axis: If a point (x,y) is reflected over the x-axis, it becomes (x,-y). Thus point A' becomes A''=(4,-1)

Rotation 180°: If a point (x,y) is rotated 180°, it becomes (-x,-y). Thus point A'' becomes A'''=(-4,1)

Answer: (second option) (-4,1)
