Answer:

\frac{-2\pm\sqrt{70}}{6}}

Step-by-step explanation:

The quadratic formula is \frac{-b\pm\sqrt{b^2-4ac}}{2a}, where a, b, and c are values in the quadratic ax^2 + bx + c. Plug in the values to get \frac{-4\pm\sqrt{4^2-4(6)(-11)}}{2\cdot6} \implies \frac{-4\pm\sqrt{16+264}}{12} \implies \frac{-4\pm2\sqrt{70}}{12} = \boxed{\frac{-2\pm\sqrt{70}}{6}}

PLEASE GIVE AN EXPLANATION WITH YOUR ANSWER! The table below shows the change in the value of shares over the last three years.
gulaghasi [49]

First, lets convert them into multipliers:

The multiplier for a:

                             25% increase = 1.25

                             40% decrease = 0.6

                             40% increase  = 1.4

Now to work out the overall percentage change, we just times all of the multipliers together, and convert it back to a percentage:

1.25 x 0.6 x 1.4 = 1.05    

So the overall multiplier is 1.05

And a multiplier of 1.05 = a <u>5% increase</u>.

That means that the percentage change is + 5%

_________________________________________

Answer:

The percentage change in shares from the start of 2013 to the end of 2015 is:

+ 5%

Note: if you haven't been taught multipliers - then ask and I'll try my best to explain!

Rectangle GHIJ is dilated to be a smaller shape. What is the name of the image after the dilation?
prisoha [69]
To know whether the shape is the pre-image or the resulting shape, we need to look at its name.

In this instance, the name of the pre-image is GHIJ.

The resulting name of the shape would be G'H'I'J'.

An apostrophe is placed after every letter to signify that it is the resulting coordinate of the original.
