What is the explicit formula for the sequence that is associated with the table?

Mathematics
1 answer:
ANEK [815]3 years ago
3 0

Answer:

see explanation

Step-by-step explanation:

Consider the values of y

\frac{2}{5}, 2, 10, 50

Consider the ratio between consecutive terms

2 ÷ \frac{2}{5} = 5

10 ÷ 2 = 5

50 ÷ 10 = 5

Since the ratio is common then the terms form a geometric sequence

The n th term of a geometric sequence is

a_{n} = a(r)^{n-1}

where a is the first term and r is the common ratio, hence

a_{n} = \frac{2}{5}(5)^{n-1} ← explicit formula

Find the equation of the straight line passing through the point (3, 3) which is perpendicular to the line y=-x-4​
Elena L [17]
Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x

The equation that shows the relationship between the variables are T = 0.112N, D = 54A and T = 62.5A

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let k represent the constant of proportionality

3) T = kN

28 = 250k

k = 0.112

i) T = 0.112N

ii) T = 0.112(300) = 33.6

iii) 98 = 0.0112N

N = 875

4) D = kA

270 = 5k

k = 54

i) D = 54A

ii) D = 54(4.5) = 243

iii) 324 = 54A

A = 6

5) T = kA

150 = 2.4k

k = 62.5

i) T = 62.5A

ii) T = 62.5(1.8) = 112.5

iii) 3(60) = 62.5A

A = 2.88

The equation that shows the relationship between the variables are T = 0.112N, D = 54A and T = 62.5A
