The gallon of water required by Dakota to fill the pool will be given as:-
V(x) = 2x⁶ + 10x⁴.
What is a function?A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
Given that:-
Dakota drained his 2,268 ft³ pool to clean it. The pool is a rectangle with an area that can be expressed as 2x⁴ + 10x² The depth that can be expressed as x² if a gallon of water has a volume of 1/60 x²The function which will represent the gallons of water will be:-
As it is given in the question the pool is of a rectangular shape so the volume of the pool will be calculated as:-
V = Area of the rectangular part x depth
V = ( 2x⁴ + 10x ²) ( x² )
V = 2x⁶ + 10x⁴.
Since the amount of the water will be equal to the volume of the pool so the function for the gallons will be given as;-
V (x) = 2x⁶ + 10x⁴.
Therefore gallon of water required by Dakota to fill the pool will be given as:-V(x) = 2x⁶ + 10x⁴.

Which function represents g(x), a reflection of f(x) = 4
across the x-axis?
O g(x) = -4(2)*
g(x) = 4(2)-*
g(x) = -4
g(x) = 4*
Using translation concepts, the function that represents g(x) is given by:
[tex]g(x) = -4\left(\frac{1}{2}\right)^x[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Function f(x) is given by:
[tex]f(x) = 4\left(\frac{1}{2}\right)^x[/tex]
Function g(x) is a reflection of g(x) over the x-axis, that is, is is multiplied by -1, hence:
[tex]g(x) = -f(x) = -4\left(\frac{1}{2}\right)^x[/tex]

What is the area of triangle ABC?
A(2,1) B(4,7) C(6,3)
Answer: 10
Step-by-step explanation:
It appears that [tex]\overline{AC} \perp \overline{BC}[/tex], so to check if this is the case, we can use the slope formula.
[tex]m_{\overline{AC}}=\frac{3-1}{6-2}=\frac{1}{2}\\m_{\overline{BC}}=\frac{3-7}{6-4}=-2[/tex]
Since these slopes are negative reciprocals, we can see that this is the case. So, we can take [tex]\overline{AC}[/tex] as the base of the triangle and [tex]\overline{BC}[/tex] as the height of the triangle, and then use the formula [tex]A=\frac{1}{2}bh[/tex].
Using the distance formula,
[tex]AC=\sqrt{(6-2)^{2}+(3-1)^{2}}=\sqrt{16+4}=2\sqrt{5}\\BC=\sqrt{(4-6)^{2}+(7-3)^{2}}=\sqrt{4+16}=2\sqrt{5}[/tex]
So, the area is [tex]\frac{1}{2}(2\sqrt{5})(2\sqrt{5})=\boxed{10}[/tex]

hope this helps :)
The value of x is x = 10
To solve a first degree equation, first: we add or subtract like terms. Finally, we split the terms of both equalities.
- In this equation, we're going to subtract the like terms -- and on the other side of the equation, we're going to also subtract the real terms.
Resolution15 + 2x = 5 + 3x
2x - 3x = 5 - 10
-1x = -10
x = 10
So, the correct value is x = 10
Carol has some dimes and quarters. If she has 19 coins worth a total of $3.10, how many of each type of coin does she have?
Answer:
Step-by-step explanation:
Equations
Let the dimes be x
Let the quarters be y
x + y = 19 (1) Multiply this equation by 0.1
0.1x + 0.25y = 3.10 (2)
0.1x + 0.1 y = 1.90 (3) Subtract 3 from 2
0.15y = 1.20 Divide by 0.15
0.15y/0.15 = 1.20/0.15
y = 8
x + y = 19
x + 8 = 19 Subtract 8 from both sides
x+8-8 = 19-8 Combine
x = 11
Answer
Carol has 8 quarters
She has 11 dimes

If 3x−4y=2 is a true equation, what would be the value of -4(3x-4y)
Answer:
-8
Step-by-step explanation:
If 3x-4y=2, then for any number a we also have a(3x-4y)=a(2) by multiplication property of equality.
Therefore, for a=-4 we have -4(3x-4y)=-4(2) which means the value of -4(3x-4y) is -8.
The value of equation - 4 (3x - 4y) will be;
⇒ - 4 (3x - 4y) = - 8
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The true equation is,
⇒ 3x - 4y = 2
Now,
Since, The true equation is,
⇒ 3x - 4y = 2 .. (i)
Hence, The value of equation - 4 (3x - 4y) is,
⇒ - 4 (3x - 4y)
Substitute from (i), we get;
⇒ - 4 (3x - 4y) = - 4 × 2
= - 8
Thus, The value of equation - 4 (3x - 4y) = - 8
