The amount of water added by the pool maintenance to make the pool 90% full is 178,200 gallons.
How much water, in gallons, did they add?The amount of water an Olympic-sized pool can hold is, 660,000 gallons.
The pool is 63% full at the moment
The of water in the pool now is:66% of 660,000 gallons
If the pool is 90% full then the amount of water in the pool is:
90% of 660,000 = 594,000 gallons
The amount of water added by the pool maintenance is:
Amount of water added = 90% of 660,000 - 63% of 660,000
594,000 - 415,800
= 178200
Thus, the amount of water added by the pool maintenance to make the pool 90% full is 178,200 gallons.

find the length of the arc of the curve from point p to point q. x2 = (y − 4)3, p(1, 5), q(8, 8)
The length of the arc of the curve from point p to point q of the equation x2 = (y − 4)3 as calculated is 8 units.
as to calculated the length of the arc we will differentiate the given equation x² = (y-4)³ with respect to y
=> 2x = 3( y - 4 )²
=> 2x = 3( y² -8y + 16)
=> 2x = 3 y² - 24y + 48
=> 3 y² - 24y + 48 - 2x = 0
now , x = 5 - 1 = 4
y = 8 - 1 =7
Therefore, length = 3 x 8² - 24 x 8 + 48 - 2x 4 = 0

h(t) = −5t² + 20t (Given)We need to find: height of the ball after 3 seconds.So, plug t = 3 in the above equation, we find:h(3) = −5(3)² + 20(3)->h(3) = −5(3)² + 20(3)->h(3) = −5(9) + 60->h(3) = −45 + 60->h(3) = 15 feetThe intersection of Beech Street and fourth Street is 150 yards east of the intersection of Fort Street and Clover Street how many yards south is it
The amount of yards south that the intersection of Fort Street and Clover Street is given as follows:
450 yards.
How to obtain the slope?The slope of an inclined object is obtained as the division of the vertical distance of the street by the horizontal distance of the object.
The distances are classified as follows:
Vertical: south is negative, north is positive.Horizontal: west is negative, east is positive.The slope of the street is given as follows:
-3.
The east distance is given as follows:
150 yards.
Thus the south distance can be identified applying the slope as follows:
-3 = S/150
S = -3 x 150
S = -450 yards.
The negative number represents that the direction is south, hence the distance is only of 450 yards.

What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
As per the given function,
g(x) = |x - 3|
Since it is a mode function thus the value of the function will always positive.
Thus, the range will be [0, ∞) or all positive real numbers.
In the function h(x) = x - 3 here we have negative real numbers as well as positive thus the range of it will be all real numbers.

How do you solve a system of three equations in two variables?
Pick any two pairs of equations from the system. Eliminate the same variable from each pair using the Addition/Subtraction method. Solve the system of the two new equations using the Addition/Subtraction method. Substitute the solution back into one of the original equations and solve for the third variable.
In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z) is called an ordered triple.
To find a solution, we can perform the following operations:
Interchange the order of any two equations.Multiply both sides of an equation by a nonzero constant.Add a nonzero multiple of one equation to another equation.Graphically, the ordered triple defines the point that is the intersection of three planes in space. You can visualize such an intersection by imagining any corner in a rectangular room. A corner is defined by three planes: two adjoining walls and the floor (or ceiling). Any point where two walls and the floor meet represents the intersection of three planes.

Vertex of a Parabola
The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x2 term is negative, the vertex will be the highest point on the graph, the point at the top of the “ U ”-shape.Given that:
f(x)= a(x-h)² + k

What is a parallelogram?A parallelogram is a straightforward (non-self-intersecting) quadrilateral in Euclidean geometry that has two sets of parallel sides. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size. The Euclidean parallel postulate, or one of its equivalent formulations, is a necessary precondition for both the congruence of opposite sides and opposite angles, and neither condition can be demonstrated without using it. In contrast, a quadrilateral with just one set of parallel sides is referred to as a trapezoid or trapezium in British or American English. A parallelepiped is the parallelogram's three-dimensional counterpart.

How do you find discontinuity?
There are a few ways to find discontinuities in a function. One way is to look for places where the function is not defined or where it produces an undefined result, such as division by zero. Another way is to look for places where the function exhibits a sudden change in behavior, such as a jump or a sharp turn.
To find discontinuities more formally, you can use mathematical techniques such as limits or derivatives. If you are familiar with these concepts, you can use them to identify discontinuities in a function.
For example, if you are trying to find the discontinuities of a function f(x), you can consider the limit of the function as x approaches a certain value, say x=c. If the limit of the function as x approaches c from both the left and the right is different, then there is a discontinuity at x=c. Similarly, if the derivative of the function is not defined at a certain value of x, then there is a discontinuity at that point.
