Thank you for positing your question here. Possible answer to the problem is that the10 ones is equal to 1 ten, the ungrouped number 4,000 + 900 + 10 which is total of 5,000. I hope my explanation helps.
17q you have to subtract to get the answer
Answer:

Step-by-step explanation:
step 1
<u>Find the volume of the tank</u>
we know that
The volume of a cylinder (water tank) is equal to

in this problem we have
-----> the radius is half the diameter
substitute

step 2
Find the cost

<h2>
Answer:</h2>
The quadratic function are:
option: A A) y(y + 4) - y = 6
Option: C C.) 4b(b) = 0
<h2>
Step-by-step explanation:</h2>
We know that the general equation of a quadratic equation in terms of a variable x is given by:

A)
y(y + 4) - y = 6
On simplifying the terms we have:

Hence, option: A is correct.
B)
(3x + 2) + (6x - 1) = 0

Hence, it is a linear equation.
Hence, option: B is incorrect.
C)
4b(b) = 0
it could also be written as:

Hence, it is a quadratic equation.
Hence, option: C is correct.
D)
3a - 7 = 2(7a - 3)

which is again a linear equation.
Hence, option: D is incorrect.
Step-by-step explanation:
f(x) = 3√x /4
x=0 => y = 0
x=1 => y = 0.75
x=4 => y = 1.5 ==> (4, 1.5)
x=16=>y= 3
the right answer is the second graph
