Demarco has a piece of fabric 6yd long. He uses a piece 3yd long. He cuts the rest into strips that are each 3\4 yd long. How ma

Kobotan [32]

Answer: 4

Step-by-step explanation:

Hi, to answer this question, first, we have to subtract the amount of fabric used (3yd) to the total fabric that Demarco has (6yd)

6 -3 =3yd

Finally, we have to divide the result by the length of each strip piece (3/4yd)

3÷ 3/4= 4 pieces

There are 4 3/4 yd long strips.

Identify the slope AND y-intercept of the equation below. y=4x−7

saw5 [17]

Answer:

slope = 4/=7

y int = -7

Step-by-step explanation:

slope = rise/run

slope = 4/-7

y int:

y = 4(0)-7

y= 0-7

y int = -7

Write a function of the geometric sequence with a starting term of 8 and a common ratio of 2. Find the fourth term.

Andreas93 [3]

The expression that represents well the geometric sequence is $f(n) = 8 \cdot 2^{n-1}$ and the value of the fourth term is 64. (Correct choice: B)

<h3>How to analyze geometric sequences</h3>

Geometric sequences are exponential expressions with discrete domain, whose form is presented and explained below:

$f(n) = a \cdot r^{n-1}$ , where a, r are real numbers and n is a natural number. (1)

Where:

Value of the starting term.
Common ratio of the series.

According to the statement, we know that the first term of the geometric sequence is 8 and between any two consecutive terms there is a common ratio of 2. If we know that a = 8, r = 2 and n = 4, then the fourth term of the series by means of (1) is:

$f(4) = 8 \cdot 2^{4-1}$

f(4) = 8 · 8

f(4) = 64

The expression that represents the geometric sequence is $f(n) = 8 \cdot 2^{n-1}$ and the value of the fourth term is 64.
