I forgot to label the triangle below! I just know that the cos A = 0.48. Based on this information, which angle should be marked
lianna [129]

Answer:

angle 1

Step-by-step explanation:

Using the trigonometric mnemonic SOH CAH TOA, we know that cos or cosine is the ratio between the adjacent side and hypotenuse side.

This means that if cos A = 0.48, A is the measure of the angle which it's relative adjacent side divided by the hypotenuse of the triangle will be around 0.48.

Let's try angle 2, cos (angle 2) = adjacent / hypotenuse = 7.8 / 8.9 = 0.876404494382 ≈ 0.87 ≠ 0.48. Since the proportions are not equal, this angle cannot be the one marked as A.

Since angle 3 is a right angle, the adjacent could be either side so it cannot be correct. Thus angle 1 is correct.

Steven's savings account switches from compounding interest annually to quarterly. His account earns 3% interest yearly. Steven
V125BC [204]

Answer:

$0.95 more.

Step-by-step explanation:

The principal of $500, when invested at APR of 3% for 5 years compounded annually will become

S_1 = 500(1 + \frac{3}{100})^{5} = 579.64 dollars.

Again, the principal of $500, when invested at APR of 3% for 5 years compounded quarterly will become

S_2 = 500(1 + \frac{3}{100 \times 4})^{5 \times 4} = 580.59 dollars.

Therefore, Steven will have $(580.59 - 579.64) = $0.95 more money in his account due to switching from annually to quarterly compounding. (Answer)
