Which graph represents the reflection in the x-axis of the curve y = cos x
Ber [7]

Answer:

The curve represented by Green color Dotted Lines in the attached figure represents the Reflection in x-axis of the curve y = cos x.

Step-by-step explanation:

As we know, the value of cosx lies between (-1,1) and its graph is a curve. Its value keeps on varying between -1 and 1 only depending on the value of x.

The value of y is \text{0} at x = \frac{\pi}{2}. Few values are labeled in the figure attached in the answer. The value y is 1 at x = 0.

The curve shown in blue color solid line represents the curve of y = cos x.

And the curve shown in the dotted green color in the attached figure represents the reflection in the x-axis.

Ankit deposits $800 in an account that earns 6% yearly interest compounded monthly. How much will the account be worth
Aleks [24]

Answer:

the compounded monthly formula is

total = principal * ( 1 + (rate / 12)) ^ 12*2 years

total = $800.00 * (1  + .06 / 12) ^ 24

total = $800.00 * (1.005) ^ 24

total = $800.00 * 1.1271597762

total = $901.7278209643

total = 901.73 (rounded)
