Answer:

B. The set is linearly independent because at least one of the vectors is a multiple of another vector.

Step-by-step explanation:

A set of n vector of length n is linearly independent if the matrix with these vectors as column has none of zero determinant. The set of vectors is dependent if the determinant is zero. In the given question the vectors have no zero determinants therefore it is linearly independent.

You invest $1,300 in an account that has an annual interest rate of 5%, compounded annually. How much money will be in the accou

KIM [24]

Answer:

A=Pe^rt

P= princible (1300)

e= (2.71828)- function on a graphing calculator

r = interest rate (.05 or 5%)

t = time (10 years)

A = 1300e^.05(10)

A = 1300e^.5

A = 2143.337652

A = 2143

Answer:

Step-by-step explanation:

Just do the reverse of what they did and you will always make it back to where you started. It's like someone saying, "take 2 steps forward then turn around.." how do you get back? You turn back around and take 2 steps backward.

What is the solution to the equation = 25? x = 5 x = 10 x = 25 x = 125

Brilliant_brown [7]

Answer:

x=125

Step-by-step explanation:

To solve we must find a number that when divided by 5 equals 25.

To do this we can either...

Take each answer choice and plug in the value into the x spot and see if it works...

5/5=25 WRONG

10/5=25 WRONG

25/5=25 WRONG

125/5=25 CORRECT!

ORRR... we can set the equation so that the x is alone on one side.

To do this we can multiply both sides by 5

$\frac{x}{5}$ =25 ---> x=25×5

x=125

How much water is needed to completely fill a mini-aquarium measuring 20 cm x 35 cm x 50 cm?

labwork [276]

volume = l x w x h

volume = 20 x 35 x 50 = 35,000 cubic cm

1 cubic cm = 0.001 liter

35000 x 0.001 = 35 liters of water is needed
