Write explicit equation for the sequence

Ray Of Light [21]

Step-by-step explanation:

r=14/7=28/14=56/28=2

So it is geometric

By using this equation:

a(n)=a1*(r)^(n-1)

and we have a(1)=7 , r=2

explicit equation : a(n)=7*(2)^(n-1)

School taxes for a local district are 2.5% of a household's income. The Smith household earns $80,000 per year. How much do the

Alex

Since 2.5% as a decimal is .025, the equation to get this is:

(.025)(80000)

Once multiplied, these equal 2,000. Or in other words, the Smiths pay $2,000 in school taxes per year.

The side lengths of a triangle are given by the expressions 5x + 3, 5x – 5, and 3x – 2. Write and simplify a linear

rewona [7]

Answer:

The perimeter is $P=13x-4$

Step-by-step explanation:

The perimeter of a triangle is the distance around its edges.

The given triangle has side lengths 5x + 3, 5x – 5, and 3x – 2.

The perimeter is : $P=(5x+3)+(5x-5)+(3x-2)$

Group similar terms to get:

$P=5x+5x+3x+3-5-2$

Combine the similar terms to get: $P=13x-4$

Hence the perimeter in terms of x is $P=13x-4$

Find the distance between the points (7, – 9) and ( – 2, – 4).

Masja [62]

Answer:

7.07106781187

Step-by-step explanation:

Let us use the distance formula:

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}$

x2=2

x1=7

y2=4

y1=9

$d = \sqrt{(2 - 7)^{2} + (4-9)^2}$

$d = \sqrt{(-5)^2 + (-5)^2}$

$d = \sqrt{25 + 25}$

$d = \sqrt{50}$

d=7.07106781187 (round to whatever digit neccesary)

Hope this helps!!
