Answer:

A. aₙ = (2/7)ⁿ⁻¹

Step-by-step explanation:

According to sequence we observe:

the first term is a₁ = 1
the common ratio is r = 2/7

Equation of nth term of GP:

aₙ = a₁r°⁻¹

Substitute to get:

aₙ = 1*(2/7)ⁿ⁻¹ = (2/7)ⁿ⁻¹

Correct choice is A

Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to point distance. the calculation is: d

Ronch [10]

we are given two points as

(1.0, 2.0) and (1.0, 5.0)

so,

(x1, y1)= (1.0 , 2.0)

(x2, y2)= (1.0 , 5.0)

x1=1 , y1=2

x2=1 , y2=5

now, we can use distance formula

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

now, we can plug values

and we get

$d=\sqrt{(1-1)^2+(5-2)^2}$

$d=\sqrt{(0)^2+(3)^2}$

$d=\sqrt{(3)^2}$

$d=3$

so, distance between points is 3...........Answer

A loaf of bread that is baked today costs $7. All of the bread baked yesterday is 40% off.

vovikov84 [41]

Answer:

The price of today's bread is $7.

40% of $7 is $2.80.

The price of yesterdays bread is $7-$2.80.

7-2.80=4.20

The price of yesterday's bread is $4.20

Tobin has enough money to purchase a loaf of yesterday's bread.

Hope this helps!
