Rectangle ABCD has vertices A(-4,2), B(-4,1), C(-1,1) and D(-1,2).
1. Apply the reflection over the x-axis that has a rule
(x,y)→(x,-y).
Then
A(-4,2)→A''(-4,-2);B(-4,1)→B''(-4,-1);C(-1,1)→C''(-1,-1);D(-1,2)→D''(-1,-2).2. The second transformation is rotation by 90° counterclockwise about the origin. This transformation has a rule
(x,y)→(-y,x).
Then
A''(-4,-2)→A'(2,-4);B''(-4,-1)→B'(1,-4);C''(-1,-1)→C'(1,-1);D''(-1,-2)→D'(2,-1).As you can see these points are exactly those frome the diagram.

Answers
Answer:
Domain and Range of f(x) is all real numbers i.e [tex](-\infty, \infty)[/tex]
Option 4 is correct.
Step-by-step explanation:
Given the function
[tex]f(x)=\frac{1}{4}(x^3+6x^2+5x-4) [/tex]
we have to find domain and range of the above function.
The domain of a function is the complete set of possible values of the independent variable i.e of x. The denominator function can't be equals to 0 when taking the values of x.
[tex]f(x)=\frac{1}{4}(x^3+6x^2+5x-4) [/tex]
Here the function defines at each and every value of x therefore
Domain of f(x) is all real numbers i.e [tex](-\infty, \infty)[/tex]
The range of a function is the complete set of all resulting values of the dependent variable i.e of y, after substituting the values of the domain.

Solve y=x^2 + 7 for x
Answers
y = x^2 + 7
y - 7 = x^2
sqrt(y - 7) = x
Answer:
x = sqrt(y - 7)
Hope this helps!
Final Answer:
The solutions to the equation [tex]\( y = x^2 + 7 \)[/tex] for x are: [tex]\[ x = +\sqrt{y - 7} \quad \text{and} \quad x = -\sqrt{y - 7} \][/tex]
Explanation:
To solve the equation [tex]\( y = x^2 + 7 \)[/tex] for x, you want to isolate x on one side of the equation. Here are the steps to do so:
1. **Subtract 7 from both sides**:
To isolate the [tex]\( x^2 \)[/tex] term, we first remove the constant term on the right side by subtracting 7 from both sides of the equation.
[tex]\( y - 7 = x^2 + 7 - 7 \)[/tex]
This simplifies to:
[tex]\( y - 7 = x^2 \)[/tex]
2. **Take the square root of both sides**:
To solve for x, you need to get rid of the square on the x term. This is done by taking the square root of both sides. Remember that when you take the square root of both sides of an equation, you must consider both the positive and negative square roots.
[tex]\( \sqrt{y - 7} = \pm\sqrt{x^2} \)[/tex]
Simplifying the right side (since the square root and square operations are inverses of each other), we get:
[tex]\( \sqrt{y - 7} = \pm x \)[/tex]
3. **Solve for x**:
We now have two solutions for x, a positive and a negative one, because squaring a positive or a negative number both give a positive result. Therefore, we write:
[tex]\( x_1 = +\sqrt{y - 7} \\\\ \( x_2 = -\sqrt{y - 7} \)[/tex]
So, the solutions to the equation [tex]\( y = x^2 + 7 \)[/tex] for x are:
[tex]\[ x = +\sqrt{y - 7} \quad \text{and} \quad x = -\sqrt{y - 7} \][/tex]
Remember that you can only take the square root of a non-negative number in real numbers. So if y - 7 is negative, the solutions for x would be complex numbers.
The radius of a cylinder is increased by a factor of 5. The height is not changed.
What is the effect of the increase on the volume of the cylinder?
A) The volume of the cylinder increases by a factor of 5.
B) The volume of the cylinder increases by a factor of 25.
C) The volume of the cylinder increases by a factor of 15.
D) The volume of the cylinder increases by a factor of 10.
Answers
When the radius of a cylinder is increased by a factor of 5, the volume of the cylinder increases by a factor of 25.
Explanation:The volume of a cylinder can be calculated using the formula V = πr2h, where V is the volume, r is the radius, and h is the height. In this case, the radius of the cylinder is increased by a factor of 5, but the height remains the same. Let's consider the original radius as r and the increased radius as 5r. The volume of the original cylinder is πr2h, and the volume of the new cylinder is π(5r)2h.
Simplifying the expression for the volume of the new cylinder, we get V' = 25πr2h. Comparing the volume of the new cylinder to the volume of the original cylinder, we can see that the volume has increased by a factor of 25. Therefore, statement B is correct: The volume of the cylinder increases by a factor of 25.

The correct answer is B) The volume of the cylinder increases by a factor of [tex]25.[/tex]
Let's analyze the relationship between the volume of a cylinder and its dimensions.
The volume [tex]\( V \)[/tex] of a cylinder is given by the formula:
[tex]\[ V = \pi r^2 h \][/tex]
where:
[tex]\( r \)[/tex] is the radius of the cylinder,
[tex]\( h \)[/tex] is the height of the cylinder.
Given that the height [tex]\( h \)[/tex] remains unchanged, if the radius [tex]\( r \)[/tex] is increased by a factor of [tex]5[/tex], the new radius [tex]\( r' \)[/tex] becomes[tex]\( 5r \).[/tex]
Now, let's compare the volumes before and after the increase in radius:
1. Original Volume [tex](\( V_{\text{original}} \))[/tex]
[tex]\[ V_{\text{original}} = \pi r^2 h \][/tex]
2. New Volume [tex](\( V_{\text{new}} \))[/tex]
After increasing the radius by a factor of [tex]5[/tex], the new radius [tex]\( r' = 5r \)[/tex].
[tex]\[ V_{\text{new}} = \pi (5r)^2 h = \pi (25r^2) h \][/tex]
Now, compare [tex]\( V_{\text{new}} \)[/tex] with [tex]\( V_{\text{original}} \)[/tex]
[tex]\[ \frac{V_{\text{new}}}{V_{\text{original}}} = \frac{\pi (25r^2) h}{\pi r^2 h} = \frac{25r^2 h}{r^2 h} = 25 \][/tex]

Answers
[tex]\frac{378}{486}=\frac{63}{x}[/tex]. This comes because we compare corresponding sides of the similar triangles. 378 corresponds with 486, since they are the horizontal lengths of the shadows. 63 corresponds to x, since they are the heights of Sammy and the sign. Solving this by cross multiplication:
[tex]378*x=63*486 \\378x=30618[/tex]
Divide both sides by 378:
[tex]\frac{378x}{378}=\frac{30618}{378} \\x=81[/tex]
The sign is 81 inches tall. Converting this to feet and inches, divide by 12; this gives us 6.75. We have 6 feet and 0.75 feet. 0.75 feet * 12 inches per foot = 9 inches. The sign is 6 feet 9 inches tall.

Answers
Answer:
Option c. Population: 10 shipments of 1000 cartons of eggs
sample: every 50th carton in each shipment.
Step-by-step explanation:
First we find out population :
For ten shipments of 1000 cartons of eggs. In other words in each 10 shipments there are 1000 cartons of eggs.
Therefore, 1000 × 10 = 10,000 cartons of eggs.
Population : 10,000 cartons of eggs
Now it is given that she examines every 50th carton to see how many cartons contain cracked eggs.
Hence, Sample would be every 50th carton in each shipment.
In option a and b given cartons of eggs are 1,000,000, so they would be eliminated and in option d it is given that sample is only 50th carton of eggs
Therefore, option c would be correct.

y = –x – 2
2x + 5y = −10
2x − 5y = −10
y + 4 = –(x – 5)
y – 4 = (x + 5)
Answers
Writing [tex]5x-2y=-6[/tex] in slope-intercept form:
[tex]5x-2y=-6\\5x+6=2y\\\frac{5x+6}{2}=y\\y=\frac{5}{2}x +3[/tex]
The slope of the line is the number before "x", which is [tex]\frac{5}{2}[/tex].
The slope of the perpendicular to this line is the negative reciprocal of this.
So the slope of perpendicular is [tex]-\frac{2}{5}[/tex].
To find the equation of the perpendicular line, we need a point. It is given as [tex](5,-4)[/tex] where [tex]x_{1}=5[/tex] and [tex]y_{1}=-4[/tex].
Now we use the point-slope form of a line to figure out the equation:
[tex]y-y_{1}=m(x-x_{1})[/tex]
Plugging in the values of [tex]x_{1}[/tex] and [tex]y_{1}[/tex] and [tex]m=-\frac{2}{5}[/tex], gives us:
[tex]y-(-4)=-\frac{2}{5}(x-5)\\y+4=-\frac{2}{5}x+2\\y+\frac{2}{5}x=2-4\\y+\frac{2}{5}x=-2[/tex]
Multiplying everything by 5 [to get rid of the denominator] and re-arranging gives us:
