Surface Area using the net.
Hitman42 [59]

Step-by-step explanation:

step 1. very tough question! you need the slant height (h)

step 2. h = sqr(8^2 + 3^2) = sqr(73) sqr is the square root

step 3. SA = B + ph/2 where SA is the surface area, B is the base area, and p = the lateral perimeter

step 4. we will call the hypotenuse of the right triangle c

step 5. c = sqr(13^2 + 6^2) = sqr(205)

step 6. SA = (1/2)13(6) + (13 + 6 + sqr(205))sqr(73)/2

step 7. SA = 39+ (33.3178)(8.5440)/2 = 181.3336 cm^2.

You have a $9000 bond that earns 3% interest compounded quarterly. How much is the bond word at 6 years?
Vlad1618 [11]

Answer:

$10,667.66

Step-by-step explanation:

The formula for calculating the compound interest is expressed as:

A = P(1+r/n)^nt

P is the principal = $9000

r is the rate = 3%

time t = 6years

n = 1/4

Substitute

A = 9000(1+0.03/(1/4))^6/4

A = 9000(1+0.03(4))^1.5

A = 9000(1+0.12)^1.5

A = 9000(1.12)^1.5

A = 9000(1.1853)

A = 10,667.67

Hence the amount after 6 years is $10,667.66
