What is 8.545 kilograms rounded to the nearest hundredth?

1 answer:

7 0

8.545 rounded to the nearest hundredth is 8.55. I think so because the number in the hundredth place is 4, the number on the right of it is 5. 5 is equal to 5 so the 4 turns into 5

Grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height. how high

bezimeni [28]

Given that grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height.

So if D is the diameter and h is the height of the conical pile then we can write:

D=3h

We know that diameter = 2r, where r is the radius

2r=3h

$r=\frac{3h}{2}$

Volume of conical pile is given by formula

$V=\frac{1}{3}\pi r^2h$

Given that volume is 1110 cubic feet.

Now plug the values of Volume and r into equation of volume

$1110=\frac{1}{3}\pi (\frac{3h}{2})^2h$

$1110=\frac{1}{3}\pi\cdot\frac{9h^2}{4}\cdot h$

$1110=\pi\cdot\frac{3h^3}{4}$

$1110\cdot\frac{4}{3\pi}=h^3$

$471.098631552=h^3$

take cube root of both sides

7.78103342467=h

Hence height is approx 7.78 feet.

If f(x) = x2, which of the following describes the graph of f(x - 1)? A. The graph of f(x - 1) is a horizontal shift of f(x) = x

pantera1 [17]

Answer:

Step-by-step explanation:

To understand this, we can look at the vertical & horizontal translations of a parabola of the form $f(x)=x^2$

A vertically translated parabola has the form $f(x)=x^2+k$ , where k is the vertical shift upward when k is positive and vertical shift downward when k is negative.
A horizontally translated parabola has the form $f(x)=(x-a)^2$ , where a is the horizontal shift rightward when a is positive and horizontal shift leftward when a is negative.

When we replace x of the original function with (x-1), we have $f(x)=(x-1)^2$ . According to the rules, this means that the original function is shifted 1 unit right (horizontal shift).

Correct answer is A.
