x + y=-24
the proof was in the pudding
how do you derive 8 sin (5x-1)?
Hello! You know that the Area of a circle is r^2π, right? You only need to apply that formula to find it. You are given the diameter, which is also writeable as 2r. So you have that 2r=123.8 (cm, I presume?). You can therefore extract the radius as (123.8):2= 61.9 cm. You can now find the Area, which is 61.9*61.9*π=3831.61π cm
Hope that helped :)
Beauty of Mathematics.
Hey, put on a coat! It’s like 20 degrees outside!
aww, someone made snow angles
what acute picture
2. The length of a diagonal of a square is 24 sqrt 2 millimeters. Find the perimeter of the square. If the answer is not a whole number, please leave it in simplified radical form.
And if possible, explain procedure.
I can’t really see the image you posted, so, perhaps, if you want, try submitting it again :)
For the second problem: we have to apply Pythagoras Theorem. I know. I know.
So, we can set like a generic value “k” for the side of the square. We can then say that the perimeter will be 4k, right?
Now we are applying Pythagoras, so we have that a^2+b^2=c^2.
But we also know that the figure we are considering is a square, therefore, a=b=k, and c=length of the diagonal, therefore 24√2
so we have 2(k^2)=(24√2)^2
which leads us to 2(k^2)=1152
so k= √576= 24
yes, it does!
Basically log3(-5) is saying, what number will equal -5 when it is set as the power of three. As you are then doing 3 to the power of this number it will simply equal -5.
I hope this made sense?
Let us consider the graph
for every odd value of x we will have y=-1 and for every even x we will get y=1 such that the graph will literally be the same two points again and again as x increases! As one is a minus number and the other positive it will intercept the x axis everytime x increases by 1! As x will go on to infinity(also it will go to negative infinity at the other side) there will be an infinite amount of x-intercepts (: Hope this helped!
here’s the graph if you’re interested > http://www.wolframalpha.com/input/?i=y%3D%28-1%29%5Ex
