Answer:
4 x 10^12
Step-by-step explanation:
4,000,000,000,000
We have 50:4000, then divide by 50 on both sides to get 1:80, which is B
The equation we're given looks like:
Substituting the information we're given, we have:
This is the same as:
which gives us an answer of $1392.70.
<h2>height = 8cm</h2><h2>_______________</h2>
<u>Step-by-step explanation:</u>
<h3>base = 4cm</h3><h3>area = 16cm²</h3>
height = ?
area = 1÷2 × base × height
16cm² = 1/2 × 4cm × height
height = (2 × 16)÷4
<h3>height = 8cm</h3><h2>_______________</h2><h2>FOLLOW ME</h2>
Given, y varies directly as the cube of x.
So, [tex] y=kx^3 [/tex]
By using the order pair (4, 16) we can get x=4 and y=16.
Now plug in these values in the above equation.
So, 16=k*4^3
16 = k *64
16/64 = k (By dividing each sides by 64).
So, k=1/4
So, the equation for this variation is y= 1/4*x^3
Now we need to find the value of y for x=2.
So, plug in x=2 in the above equation. Hence,
y=1/4* 2^3
=1/4*8
=8/4
=2
So, y=2
