Answer:

5b(2 - 5b²)

Step-by-step explanation:

Simply take out GCFs to factor out the expression:

Step 1: Factor out GCF of 5

5(2b - 5b³)

Step 2: Factor out GCF of <em>b</em>

5b(2 - 5b²)

We can't factor the quadratic any further so that is our final answer.

Find the oth term of the geometric sequence 7, 14, 28, ...
yaroslaw [1]

Answer:

The nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}

Step-by-step explanation:

Given the geometric sequence

7, 14, 28, ...

We know that a geometric sequence has a constant ratio 'r' and is defined by

a_n=a_1\cdot r^{n-1}

where a₁ is the first term and r is the common ratio

Computing the ratios of all the adjacent terms

\frac{14}{7}=2,\:\quad \frac{28}{14}=2

The ratio of all the adjacent terms is the same and equal to

r=2

now substituting r = 2 and a₁ = 7 in the nth term

a_n=a_1\cdot r^{n-1}

a_n=7\cdot \:2^{n-1}

Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}

The Library is 1.75 miles directly north of the school the park is 0.6 miles directly south of the school.How far is the library
statuscvo [17]

Answer: 2.35 miles

Check out the attached image below. A drawing often helps visualize the problem. In this case, all three locations are along the same vertical line. The distances 1.75 and 0.6 can be added up as those smaller segments form the entire distance we want (from park to library). So that's how I got 1.75+0.6 = 2.35
