Answer: f(n)=(n-7)(n+5)


Step-by-step explanation:

1. You can rewrite the quadratic equation as following:

f(n)=n^{2}-2n-35

2. To factor it, you must find two number that when you add them you obtain -2 and when you multiply them you obtain -35. These would be 5 and -7.

3. Therefore, you can write the function in the following intercept form:

f(n)=(n-7)(n+5)

Check the true statements below:
valentinak56 [21]

Answer:

a) False

b) False

c) True

d) False

e) False

Step-by-step explanation:

a. A single vector by itself is linearly dependent. False

If v = 0 then the only scalar c such that cv = 0 is c = 0. Hence, 1vl is linearly independent. A set consisting of a single vector v is linearly dependent if and only if v = 0. Therefore, only a single zero vector is linearly dependent, while any set consisting of a single nonzero vector is linearly independent.

b. If H= Span{b1,....bp}, then {b1,...bp} is a basis for H. False

A sets forms a basis for vector space, only if it is linearly independent and spans the space. The fact that it is a spanning set alone is not sufficient enough to form a basis.

c. The columns of an invertible n × n matrix form a basis for Rⁿ. True

If a matrix is invertible, then its columns are linearly independent and every row has a pivot element. The columns, can therefore, form a basis for Rⁿ.

d.  In some cases, the linear dependence relations among the columns of a matrix can be affected by certain elementary row operations on the matrix. False

Row operations can not affect linear dependence among the columns of a matrix.

e. A basis is a spanning set that is as large as possible. False

A basis is not a large spanning set. A basis is the smallest spanning set.

Answer: Experimental probability of landing on white = 177/1000.

Theoretical probability of landing on white = 1/5.

The larger the amount of spins, the greater the likelihood that the experimental probability will be close to the theoretical.

What is the answer 101/8+(35/8+27/8
suter [353]

Answer:

\frac{163}{8}

Step-by-step explanation:

The sum already has common denominators so there is no need to change the denominators. Just add the numerators.

\frac{35}{8} + \frac{27}{8} = \frac{62}{8}

\frac{101}{8} + \frac{62}{8} = \frac{163}{8}
