A point at (15, 42) is reflected over the x-axis. What are the coordinates of the reflected point? Enter your answer by filling in the boxes. ( , )
Answer:
(15, -42)
Step-by-step explanation:
Reflect Over X-Axis Formula
The following formula is used to reflect a coordinate point about the x-axis.
(X2,Y2) = (X1,Y1) * (1,-1)
Where X2 and Y2 are the new reflected coordinates
X1 and Y1 are the original coordinate points
Reflect Over X-Axis Definition
Reflection over the x-axis is the process of producing a coordinate point that is mirrored across the x-axis of the coordinate plane. That is it has the same X coordinate and opposite y4 coordinate.
Reflect over X-Axis Example
How to reflect over the x-axis?
First, determine the original coordinate points.
For this example, we will say the coordinate points are (4,5).
Next, calculate the new coordinate points.
Using the formula above we calculate the new reflected points as (4,5)*(1,-1) = (4,-5).

Find the least common multiple of 20 and 25.
Answer:
The least common multiple of 20 and 25 is 100.
Answer:
100
Step-by-step explanation:
In order to find the least common multiple of 20 and 25, first find the prime factors of 20 and 25.
20 = 2*2*5
25 = 5*5
Here,
Common factor = 5
Uncommon factors = 2, 2, 5
Least common multiple of 20 and 25 = Common factors* Uncommon factors
= 5*(2*2*5)
= 5*20
= 100

Nairobi and Zanzibar are two cities in Africa. Zanzibar’s population is 1.5 million. If the population of Nairobi is 16% greater than Zanzibar’s, what is its population? Write your answer as an integer.
Answer:
1.74 million (1,740,000)
Step-by-step explanation:
First we have to find 16% of 1.5 million
0.16 x 1,500,000 = 240,000
Now we add this to the original 1.5m
1,500,000 + 240,000 = 1,740,000
There is roughly 1.74 million in the population of Nairobi

The one possible solution is Justin has 8 nickels and 16 dimes.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, Justin has x nickels and y dimes, having a maximum of 28 coins worth a minimum of $2 combined.
0.05x + 0.1y ≤ 2.
x ≤ 8 and y ≤ 22.
The possible solution of these systems of inequalities is (8, 16).

If you where to drop a ball it would fall towards the ground, no go up and Graph A represents this properly.
Answer:
The answer is neither C.
Step-by-step explanation:
The answer is C because as an object goes down/falls, The potential energy decreases. This is the same if an object is going up. This means that neither of the graphs are correct. Both graphs show that the object is moving which means it is using energy.

The regions bounded by the graphs of y=4x and y=x−x2+x3 are shaded in the figure above. What is the sum of the areas of the shaded regions?
Find where the two curves intersect:
[tex]4x = x - x^2 + x^3[/tex]
[tex]\implies x^3 - x^2 - 3x = 0[/tex]
[tex]\implies x (x^2 - x - 3) = 0[/tex]
[tex]\implies x = 0 \text{ or } x^2 - x - 3 = 0[/tex]
Completing the square gives
[tex]x^2 - x - 3 = \left(x - \dfrac12\right)^2 - \dfrac{13}4 = 0[/tex]
and solving for x,
[tex]\implies x = \dfrac12 \pm \sqrt{\dfrac{13}4} = \dfrac{1 \pm \sqrt{13}}2[/tex]
The total unsigned area between the two curves is then
[tex]\displaystyle \int_{(1-\sqrt{13})/2}^{(1+\sqrt{13})/2} \left|4x - \left(x - x^2 + x^3\right)\right| \, dx[/tex]
[tex]= \displaystyle -\int_{(1-\sqrt{13})/2}^0 \left(4x - \left(x - x^2 + x^3\right)\right) \, dx + \int_0^{(1+\sqrt{13})/2} \left(4x - \left(x - x^2 + x^3\right)\right) \, dx[/tex]
[tex]= \displaystyle -\int_{(1-\sqrt{13})/2}^0 \left(3x + x^2 - x^3\right) \, dx + \int_0^{(1+\sqrt{13})/2} \left(3x + x^2 - x^3\right) \, dx[/tex]
where we use the definition of the absolute value function to split up the integral at the point where one curve "overtakes" the other - in other words, y = 4x lies above the curve y = x - x² + x³ when x > 0, and vice versa otherwise.
We have the antiderivative
[tex]\displaystyle \int (3x + x^2 - x^3) \, dx = \dfrac{3x^2}2 - \dfrac{x^3}x - \dfrac{x^4}4 + C[/tex]
so that by the fundamental theorem of calculus, the area we want is
[tex]\displaystyle \int_{(1-\sqrt{13})/2}^{(1+\sqrt{13})/2} \left|4x - \left(x - x^2 + x^3\right)\right| \, dx = \boxed{\dfrac{73}{12}}[/tex]

The regions bounded by the graphs y₁ = 4x and y₂ = x − x² + x³ are shaded in the figure above.

4x = x − x² + x³
x³ − x² − 3x = 0
x = −1.303, 0, 2.303

[tex]\rm Area = \int _{-1.303}^{2.303} ( y_1 - y_2 ) dx\\\\\\Area = \int _{-1.303}^{2.303} 4x - (x-x^2+x^3) dx\\\\\\Area = \int _{-1.303}^{2.303} 4x - x+x^2-x^3) dx\\\\\\Area = \int _{-1.303}^{2.303} (3x + x^2-x^3) dx\\\\\\Area = \begin{bmatrix} \dfrac{3}{2}x^2 + \dfrac{1}{3}x^3 - \dfrac{1}{4} x^4 \end{bmatrix} _{-1.303}^{2.303}\\\\\\Area = \dfrac{73}{12}\\\\\\Area = 6.0833[/tex]
