The first five terns of the sequence are - 1,4,1,4,1

<h3>What is a sequence?</h3>

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. It has members, just like a set does. The length of the sequence is determined by the number of items.

an = 5 - a n-1

a1 = 1

a2 = 5 - (1) = 4

a3 = 5 - (4) = 1

a4 = 5 - (1) = 4

a5 = 5 - (4) = 1

The answer would be 3.

In order to find this you must place the values in where you see the letters. So start with the letters and plug in.

mx - y

Since m = 1, put that in.

(1)x - y

Since x = 5, put that in

(1)(5) - y

Since y = 2, put that in

(1)(5) - (2)

Now follow the order of operations and solve

(1)(5) - 2

5 - 2

12. Find the distance between points P(-1, 2) and Q(-3, 4).

marusya05 [52]

Answer:

D=2.82

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

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

Where

$(x_1,y_1) = (-1,2)$

$(x_2,y_2) = (-3,4)$

Replacing these values in the distance formula

$D =\sqrt{(-1-(-3))^2+(2-4)^2}$

$D =\sqrt{(-1+3)^2+(-2)^2}$

$D =\sqrt{(2)^2+4}$

$D =\sqrt{4+4}$

$D =\sqrt{8}$

$D= 2.8284$

Hence the Distance is 2.82 units

kupik [55]

Answer:

1,020 seconds

Step-by-step explanation:

-We first subtract the two times to get the time before dinner is ready(after arriving home):

$\bigtriangleup Time=Dinner \ Time-Arrival Time\\\\=5:51-5:34\\\\=(51-34)\ minutes\\\\=17\ minutes$

-Having calculated this time difference, we convert it into seconds using the ratio 1 minute =60 seconds:

$\bigtriangleup Time=17\ \times 60\ seconds\\\\=1020\ seconds$

Hence, her dinner is ready 1,020 seconds after arriving home.,

How do I solve this

igomit [66]

The area of a circle is pi*r^2=a since we know the diameter is 24 and radius is half the diameter the r=12 so the area of the half circle = 1/2*pi*12^2 and the area of the square is simply base*height = 24*24 then the area with the missing portion must be 24*24-1/2*pi*12^2 = 576-72pi= approximately 349.8cm

$65 times the percentage in its decimal form
$65• .18 = $11.7
This means less than 13
The other one with the skateboard is the same
$50 times the percentage in its decimal form
$50• .40 = $20
