Use proportional math. 12 is to $36 as 8 is to ___. Or 12/36 is to 8/X.
36 x 8 = 288 divided by 8 = 24

26.   2x^2 +4x -10 = 0       (-4 + - (root(4^2 - 4*2*-10)))/2*2   =  
(-4 + - (root(96)))/4
(-4 + (root(96)))/4  ≈  1.45
(-4 -  (root(96)))/4  ≈  -3.45

27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore   x -2 = 0    x +3 = 0    x -5 = 0   so   f(x) = 0 when x = 2, -3 or 5

The 9th and the 12th term of an arithmetic progression are 50 and 65 respectively. find the common difference
Rzqust [24]

The first term of the arithmetic progression exists at 10 and the common difference is 2.

<h3>How to estimate the common difference of an arithmetic progression?</h3>

let the nth term be named x, and the value of the term y, then there exists a function y = ax + b this formula exists also utilized for straight lines.

We just require a and b. we already got two data points. we can just plug the known x/y pairs into the formula

The 9th and the 12th term of an arithmetic progression exist at 50 and 65 respectively.

9th term = 50

a + 8d = 50 ...............(1)

12th term = 65

a + 11d = 65 ...............(2)

subtract them, (2) - (1), we get

3d = 15

d = 5

If a + 8d = 50 then substitute the value of d = 5, we get

a + 8 * 5 = 50

a + 40 = 50

a = 50 - 40

a = 10.

Therefore, the first term is 10 and the common difference is 2.

Can you divide 2 by 9? Explain your response.
Sergio039 [100]

Answer:

0.22222222222

Step-by-step explanation:

To divide two by nine, you need to use your long division skills. Unfortunately, this interface doesn't lend itself well to showing you the actual long division problem, so try to follow the steps with me.

draw a division symbol (should look like half a rectangle). Put the 9 in front of the rectangle and a 2 inside it. Make the top of the rectangle long.

Note that the result of the division 2÷9 is not an exact value and is equivalent to recurring decimal 0.22... (which has 2 as the period).
