Suppose you buy a CD for $300 that earns 3% APR and is compounded quarterly. The CD matures in 3 years. How much will this CD be

andrew-mc [135]

Given: Principal Amount (P) = $300

The rate of interest (r) = (3/4) compounded quarterly.

No. quarters in 3 years (n) = 3×4 = 12

To find: The amount for the CD on maturity. Let it will be (A)

Formula: Compound Amount (A) = P [ 1 + (r ÷100)]ⁿ

Now, (A) = P [ 1 + (r ÷100)]ⁿ

or, = $300 [ 1 + (3 ÷400)]¹²

or, = $300 × [ 403 ÷ 400]¹²

or, = $300 × 1.0938069

or, = $ 328.14

Hence, the correct option will be C. $328.14

An object is 3.6 m from the pinhole. Its image is 4.2 cm from the opposite side of the pinhole. The height of the image is 0.8 c

madreJ [45]

Answer:

Height of the object is 68.6 cm.

Step-by-step explanation:

The height of the object can be determined by:

$\frac{object distance from pinhole}{image distance from pinhole}$ = $\frac{object height}{image height}$

From the given question;

object distance from pinhole = 3.6 m = 360 cm

image distance from pinhole = 4.2 cm

height of image = 0.8 cm

So that;

$\frac{360}{4.2}$ = $\frac{object height}{0.8}$

⇒ object height = $\frac{360*0.8}{4.2}$

= $\frac{288}{4.2}$

= 68.571

object height = 68.6 cm

Thus, the height of the object is 68.6 cm.
