Answer: ⇒V=π×32×53=45×π3≈47.124 cubic cm
Hope this helps!!
Answer:
Hello! Okay So I will help you with the ones I know. A rhombus has equal sides just like a square.
1. AB = CD = True
It is true because they are equal sides.
2. BC = AD = True
This is also true because the side are equal
I hope this helped a little!
The answer is 9
1 2/3 is 5/3. If you need to show your work of how to do it with fractions let me know but the easiest way is make it a decimal of 1.6666 and put it in a calculator and you get 9.
3:11 because 9 and 33 divided by 3 = to the answer
For f(x)=ax²+bx+c
if a is positive, then it is concave up and the verx is minimum
if a is ngative then it is concave down and vertex is maximum
hack: in form f(x)=ax²+bx+c, the x value of vertex is -b/2a
to find y value, just subsitutte that value for x in f(x)
so
y=-1x²+4x-4
negative, so vertx is max
x value of vertex is -4/(2*-1)=-4/-2=2
find f(2) or subsitute 2 for x
y=-1(2)²+4(2)-4
y=-1(4)+8-4
y=-4+4
y=0
maximum is 0
A is answer
