I’ll assume the interest compounds annually (once a year).

Use A=P(1+r/n)^nt to solve!

A = Amount after time
P = Initial value
t = Time in years
r = Rate
n = Number of compounds(¿?)

A=200(1+0.08/1)^1x3

There is $251.94 in the account after three years!

Which equation represents the hyperbola in general form?

valina [46]

ANSWER

$9 {y}^{2} - 4 {x}^{2}- 36y + 16x - 16 = 0$

EXPLANATION

The standard equation of the hyperbola is

$\frac{ {(y - 2)}^{2} }{4} - \frac{ {(x - 2)}^{2} }{9} = 1$

We multiply through by 36 to obtain:

$9 {(y - 2)}^{2} - 4( {x - 2)}^{2} = 36$

We now expand to get,

$9( {y}^{2} - 4y + 4) - 4( {x}^{2} - 4x + 4) = 36$

Expand :

$9 {y}^{2} - 36y + 36 - 4 {x}^{2} + 16x - 16 = 36$

To get the general form, we equate everything to zero to get,

$9 {y}^{2} - 4 {x}^{2}- 36y + 16x - 16 = 0$

The correct choice is D.

A rectangular pyramid has a base area of 24in² and a volume of 48in³. What is the height of the pyramid?

alexgriva [62]

height of pyramid = 3*(V/A)

V=48in^3

A=24in^2

So 3*(48/24) = 3*2=6

Answer:

a. 14:45pm (It's really easy to convert to a 24-hour clock time, all you need to do is add 12 hours onto the hour. Eg. 2 + 12 = 14 so it will be 14:45.pm

b. The length of time between 11:45am and 2:45pm is 3 hours.

I don't know what c is sorry.

Hope that helps. x
