Answer:
-3.786 × 10^7
Step-by-step explanation:
Put an decimal behind a number 1-10
but keep the negative sign
so you should get
-3.7860000
Then you count how many numbers are to the right of the decimal which is 7.
That number will become the exponent and then you take away the zeros
You should then have
-3.786 × 10^7 as your answer.
Easily you can try each formula with x=-2
because we know f(-2)=-1
So ,in this way D is correct Only!!
I got 5x^2 - 30x................
The median of the data below is 1
Let's make the first even integer m and the second even integer n. The square of the first, decreased by the second is 130 is:
-n=130 ---> Add n to each side
=130+n ---> Take the square root of each side
m=±
Let's look at the first square number above 130, which is
. <em>m</em> is 12, therefore the next consecutive even integer is 14.
=144
144-14=130
The two consecutive integers are 12 and 14
