Answer:

36 ft

Step-by-step explanation:

Let the length be l

Volume = Base Area × Height

1728 = 6 × l × 8

48l = 1728

l = 36 ft

Length is 36ft

A person invest $1800 in a account that earns 2.46% annual interest. Find when the value of the investment teachers $3500

GrogVix [38]

Answer:

28 years

Step-by-step explanation:

To find the number of years that the investment will reach $3500, we can use the formula of compound interest:

P = Po * (1+r)^t

where P is the final value, Po is the inicial value, r is the annual interest and t is the time in years.

In this question, P = 3500, Po = 1800 and r = 2.46% = 0.0246, so:

3500 = 1800 * (1+0.0246)^t

1.0246^t = 3500/1800

1.0246^t = 1.9444

Using logarithm in both sides:

log(1.0246^t) = log(1.9444)

t*log(1.0246) = 0.2888

t * 0.0106 = 0.2888

t = 0.2888 / 0.0106 = 27.2453 years

So the investment will reach $3500 after 28 years (rounding the result up, because after 27 years the investment will not reach $3500)

What is the most precise term for quadrilateral ABCD with vertices A(3,1) , B(4,5) , C(7,5) , D(7,2) answer choices; A. KITE B.

SOVA2 [1]

Answer:

Step-by-step explanation:

Given are the vertices of a quadrilateral.

WE have to find the name of the quadrilateral

WE have slope of AC = (5-1)/(7-3) = 1

and slope of BD = (2-5)/(7-4) = -1

Since m1m2 =-1 we get

the diagonals cut at right angles

This property is special property for square, rhombus and kite only.

Let us check if diagonals bisect each other

Mid point of AC = $(\frac{3+7}{2} ,\frac{1+5}{2} =(5,3)$

Mid point of BD = $(\frac{4+7}{2} ,\frac{2+5}{2} =\neq 5,3)$

Since diagonals do not bisect this is neither rhombus nor square.

Only possibility is kite
