Answer:
$13912.50
Step-by-step explanation:
First you find how much carpet you need by finding the area of the room.
18.75*28= 525ft^2
Then multiply the amount of carpet needed by 26.50 to find the total cost.
525*26.50= 13912.50

Answer:
Option (c) is correct.
The interest gained by Gini in 6 years is $ 866.34
Step-by-step explanation:
Given: Gina invests $1,677 in an account paying 8.61% simple interest annually for 6 years.
We have to calculate the interest gained by Gina in 6 years.
Using formula for simple interest

Where,
S.I = simple interest
P is principal
R is interest rate
T is time
Given : P = $ 1677
R = 8.61%
T = 6 years
Substitute, we get,

Simplify, we get,
S.I. = $ 866.3382
Rounding off to nearest hundred we get, Interest is $866.34
Thus, the interest gained by Gini in 6 years is $ 866.34
Answer with Step-by-step explanation:
We are given that the set of vectors
is lineraly dependent set .
We have to prove that the set
is linearly dependent .
Linearly dependent vectors : If the vectors 
are linearly dependent therefore the linear combination

Then ,there exit a scalar which is not equal to zero .
Let
then the vector
will be zero and remaining other vectors are not zero.
Proof:
When
are linearly dependent vectors therefore, linear combination of vectors of given set

By definition of linearly dependent vector
There exist a scalar which is not equal to zero.
Suppose
then 
The linear combination of the set 

When 
Therefore,the set
is linearly dependent because it contain a vector which is zero.
Hence, proved .
