Hey there!

You can find a number halfway between two numbers by simply adding them together and then dividing by two!

13/15+14/15=1 4/5

1 4/5÷2=9/10

Your number is 9/10.

I hope this helps!

Solve the quadratic equation 3x^2 +x-5=0 give your answers to two decimal places

Ipatiy [6.2K]

$x = \frac{(-1+\sqrt{61})}{6}$

$x = \frac{(-1-\sqrt{61})}{6}$

Explaination:

Quadratic Equation 3x²+x-5=0

The quadratic formula is the solution of the quadratic equation. There are various methods to solve the quadratic equation instead of using the quadratic formula, such as AC method (factoring), completing the square method, or graphing method.

Standard Quadratic equation is :

ax²+bx+c=0

The quadratic formula is :

x = $\frac{-b+-\sqrt{b^{2}-4ac} }{2a}$

now put the values of a, b, c in this formula

a = 3, b= 1, c=-5

x = $\frac{(-1+\sqrt{61})}{2*3}$

x = $\frac{(-1-\sqrt{61})}{2*3}$

So final answer,

$x=\frac{-1+\sqrt{61}}{6}$

$x=\frac{-1-\sqrt{61}}{6}$

Find the nth term of this number sequence 2, 4, 6, 8,

ELEN [110]

Answer:

$a_n = 2n$

Step-by-step explanation:

Given sequence is: 2, 4, 6, 8,.....

Here, a = 2, d = 4 - 2 = 2

To find: $a_n$

$a_n = a + (n - 1)d \\ \\ \therefore \: a_n = 2 + (n - 1)2\\ \\\therefore \: a_n = 2 + 2n -2\\ \\\therefore \: a_n = 2n \\ \\$
