Bingel [31]3 years ago
5 0

Answer:

Step-by-step explanation:

a1=7

a2=13

c.d. d=13-7=6

an=a1+(n-1)d

an=7+(n-1)6=7+6n-6=6n-1

recursive formula

c.d .=an-a(n-1)

6=a_{n}-a_{n-1}

a_{n}=a_{n-1}+6

Step-by-step explanation:

remember that to get from positive to negative you have to go from positive to 0 then to negative .

however the easiest way of solving this is

If a is directly proportional to b/2 and a=1 when b=10, what is the value of a when b=35
iris [78.8K]
The value of a would be 3.5, as a=1 when b=10 means that a is worth 1/10 of b's value.

Ashley has 20 pieces of candy in a bag: 2 mint sticks, 4 jelly treats, and 14 fruit tart chews. If she eats one piece every 8 mi
AleksAgata [21]
The probability that her first treat is jelly is 4/20. Since she eats the candy and does not replace it, the probability the second treat is jelly would be 3/19 (1 less jelly and 1 less total candies). You would then multiply (4/20) by (3/19). That is your answer.

if a right triangle has one side measuring 3√2 and another side measuring 2√3, what is the length of the hypotenuse?
lina2011 [118]

Answer:

<h2>\sqrt{30}</h2>

Step-by-step explanation:

Given,

Perpendicular ( p ) = 3√2

Base ( b ) = 2√3

Hypotenuse ( h ) = ?

Now, let's find the length of the hypotenuse:

Using Pythagoras theorem:

{h}^{2}  =  {p}^{2}  +  {b}^{2}

plug the values

{h}^{2}  =  {(3 \sqrt{2} )}^{2}  +  {(2 \sqrt{3} )}^{2}

To raise a product to a power, raise each factor to that power

{h}^{2}  = 9 \times 2 + 4 \times 3

Multiply the numbers

{h}^{2}  = 18 + 12

Add the numbers

{h }^{2}  = 30

Take the square root of both sides of the equation

h =  \sqrt{30}

Hope this helps...

Best regards!!
