Given:
19, 180, 181
To be able to determine if the given lengths form a right triangle, the following condition must be met:
Let's check.
a.) At a = 19, b = 180, c = 181
Therefore, the given lengths could form a right triangle at a = 19, b = 180 and c = 181.
The answer is yes.
It just happened to be that we got the right answer on the first try, you must also examine at a = 180, b = 181, c = 19 and a = 181, b = 19, c = 180 if the first try didn't meet the right condition.
If you failed to get, then the given lengths could not form a right triangle. The answer would be no.
A) 26 + 18 = D
Where D = Dad's age.
B) No it isn't. You solve the above equation and it equals 44.
C) The first age comparison is 26 years apart, both going up by 8 each time, so by adding 8 to 36, it equals 44, which isn't 42.
Answer: The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.
Step-by-step explanation:
x is the price of the battery
x + 1.50 is the price of the torch
x + (x + 1.50) is 2.50
x + (x + 1.50) = 2.50
2x = 2.50 - 1.50
2x = 1
x = 1/2
x = 0.50
The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.
Answer:
the matrix described in the question is a linearly independent matrix, and linearly dependent matrix has a unique solution. <em>see further explanation below</em>
Step-by-step explanation:
For any matrix to have a pivot column in all its column, it means that the matrix must be linearly dependent
Thus, as the columns are linearly independent , the system of equation have a unique solutions
.
