Answer:
x is greater than or equal to four because it is a closed circle and shading to the right which is up
Step-by-step explanation:
Answer: 16/45 of the spool
Step-by-step explanation:
2/5 of 8/9
2/5 * 8/9 = 16/45 (multiply numerators, and multiply denominators)
Cannot be further simplified.
"A parabola is curved instead of linear, in your case it is probably just facing up or down so I won't get into square roots for now.So the quadratic equation that you probably have had to memorize (or will soon) is:
x=(-b[+or-]√(b²-4ac))/2a when you have an equation like ax²+bx+c=0Now where does the curve shape come from? You see that little pesky plus or minus in the equation? That's because there are always 2 values (inputs) that will generate the same output. Example:y=x²(2)²=4(-2)²=...4So if you were to follow this pattern, and plot the points on a graph, you would end up with a curve. You end up with a curve because the slope is constantly increasing.
And this is actually where you start the study of Calculus(!), which is all about measuring slopes (And a bunch of other stuff, but this is the easiest part to explain). Actually, in this case of y=x², the slope at any given point (funnily enough) is equal to 2 times your x-value.
The point is, your line is curved because unlike a linear equation, the slope is changing (at a constant rate)."
110x4= 2
70x6= 2
60x7= 1
Hope this helps.
23 ^ (-2) is equal to 1 / (23^2). 23 to the second power is equal to 529. Thus, the answer would be 1/529. None of the answers are correct. 8 squared is 64.
