Answer:
A. right 2, up 3
Step-by-step explanation:
We are asked to find the transformation that occurs from the graph of [tex]f(x)=x^2[/tex] to [tex]f(x)=(x-2)^2+3[/tex].
Let us recall transformation rules:
[tex]f(x)\rightarrow f(x+a)=\text{Graph shifted to left by a units}[/tex]
[tex]f(x)\rightarrow f(x-a)=\text{Graph shifted to right by a units}[/tex]
[tex]f(x)\rightarrow f(x)-a=\text{Graph shifted downwards by a units}[/tex]
[tex]f(x)\rightarrow f(x)+a=\text{Graph shifted upwards by a units}[/tex]
Upon looking at our given functions, we can see that graph of [tex]f(x)=x^2[/tex] is shifted to right by 2 units as 2 is inside parenthesis. The graph is shifted upwards by 3 units as we have positive 3 outside parenthesis.
Therefore, option A is the correct choice.
If AB = 8, BC = 5, and CA = 7. list the angles of
AABC in order from smallest to largest measure.
Answer:
∠A, ∠B, ∠C
Step-by-step explanation:
In a triangle the smallest angle is opposite the shortest side, and the largest angle is opposite the longest side, therefore:
∠A < ∠B < ∠C
Answer:
a,b,c
Step-by-step explanation:
The angle opposite the longest side has the largest angle measure, the angle opposite the shortest side has the most small angle measure etc.
Since BC is the shortest line, the angle opposite will have the smallest measure, this is ∠a.
CA is in the middle with length this means that the angle opposite of it will have an angle measure in between that of the other angle measures. This is ∠b
AB has the longest length, therefore, the angle opposite it will have the largest measure, this is ∠c
A box can hold 24 crayons. How many boxes must be used to put all of Mr.Syed's 98 crayons into boxes?
Answer:
5 boxes
Step-by-step explanation:
Given:
Total crayons : 98
Capacity of each box : 24
Number of boxes of 24 crayons needed to hold 98 crayons,
= 98 ÷ 24
= 4.08 boxes.
However since we cannot have 0.08 of a box, we must round this up to the next larger whole number of boxes.
4.08 rounded up to next whole number = 5
Hence he will need 5 boxes to hold all 98 crayons

Final answer:
The rule 'y = X/4' describes division of X by 4 to find Y. The student completes the table by dividing each X value by 4 to find the corresponding Y values, providing an organized data set.
Explanation:
The student is asking about the operation indicated by the rule y = X/4, which involves division. The fraction bar signifies division. Given this rule, we can complete the table for y when x-values are provided.
For x = 4: y = 4/4 = 1
For x = 2: y = 2/4 = 0.5
For x = 9: y = 9/4 = 2.25
To organize the data in the table, you simply divide the x-value by 4 to find the corresponding y-value.
If f(x) = 5x, what is f^-1(x)?
o f^-1(x) = -5x
o f^-1(x)= -1/5x
o f^-1(x) = 1/5x
o f^-1(x) = 5x
Answer:
Third choice
Step-by-step explanation:
They are asking us to find the inverse of y=5x. To do this you just switch x and y and then remake y the subject of the equation (solve for y.)
y=5x
x=5y (I switch x and y)
x/5=y ( I divided both sides by 5)
Then you just replace y with the f^-1(x) thing
f^-1(x)=x/5
or
f^-1(x)=1/5x
If f(x) = 5x, then the inverse of the function, f⁻¹(x) is x/5.
Given that :
f(x) = 5x
Let y = f(x).
So, y = 5x
Now, interchange the values for x and y.
Then,
x = 5y
Now, solve for y.
Divide both sides of the equation by 5.
x/5 = y
So, the inverse of the function is x/5.
Hence f⁻¹(x) = x/5.

solve 2x^2 + 8 = 0 by graphing the related function
The solutions to the equation [tex]\( 2x^2 + 8 = 0 \)[/tex] are complex numbers [tex]\( x = 2i \) and \( x = -2i \), where \( i \)[/tex] is the imaginary unit.
The statement that the graph of [tex]\( 2x^2 + 8 = 0 \)[/tex] does not cross the x-axis is correct, as the graph of this equation represents a parabola that opens upwards and is centered above the x-axis, meaning it has no real roots.
To find the solutions for the equation [tex]\( 2x^2 + 8 = 0 \)[/tex], we can start by isolating [tex]\( x^2 \):[/tex]
[tex]\[ 2x^2 = -8 \][/tex]
Dividing both sides by 2:
[tex]\[ x^2 = -4 \][/tex]
Now, to solve for ( x ), we take the square root of both sides:
[tex]\[ x = \pm \sqrt{-4} \][/tex]
[tex]\[ x = \pm 2i \][/tex]
So, the solutions to the equation [tex]\( 2x^2 + 8 = 0 \)[/tex] are complex numbers [tex]\( x = 2i \) and \( x = -2i \), where \( i \)[/tex] is the imaginary unit.
These are the roots of the equation, even though they do not lie on the real number line.
Hence, while there are no real solutions, there are indeed complex solutions for the given function.

Which product is equivalent to 25x2 – 16?
Answer:
The correct answer would be 34
Step-by-step explanation:
When solving an expression, we would first solve the operator with the highest precedence. In mathematics, there are four basic operators. Addition, subtraction, multiplication and division. The precedence of Division and multiplication is higher than the precedence of Addition and subtraction. So by solving this with the precedence, we would first solve the multiplication operator which is 25 * 2, it will give 50, then we will subtract 16 from it like 50-16, which will give us 34.
Answer:
(5x+4)(5x-4)
Step-by-step explanation:
The product expression can be obtained by factorizing the expression 25x²-16 provided in the question.
The expression is a difference of two squares whose factors are generally
(a-b)(a+b)
√25x² is 5x
√16 is 4
Therefore the product required is (5x+4)(5x-4)
25x²-16 is equivalent to (5x+4)(5x-4)
What equation is the inverse of y=x^2+16
Answer:
[tex]y = \sqrt{x - 16} [/tex]
Step-by-step explanation:
[tex]y = {x}^{2} + 16[/tex]
[tex]x = {y}^{2} + 16[/tex]
[tex]x - 16 = {y}^{2} [/tex]
[tex] \sqrt{x - 16} = y[/tex]
Answer:
f^-1 (x) = ±sqrt(x-16)
Step-by-step explanation:
To find the inverse of a function, exchange x and y and solve for y
y=x^2+16
Exchange x and y
x = y^2 +16
Then solve for y
Subtract 16 from each side
x-16 = y^2 +16-16
x-16 = y^2
Take the square root of each side
±sqrt(x-16) = sqrt(y^2)
±sqrt(x-16) = y
The inverse
f^-1 (x) = ±sqrt(x-16)

What is the distance between the points (2, 8) and (-7, -4) in the coordinate plane?
The distance between the points (2, 8) and (-7, -4) is 15 units.
Using the distance formula derived from the Pythagorean theorem, the distance between the points (2, 8) and (-7, -4) is found to be 15 units.
The distance between two points in the coordinate plane can be found using the distance formula, which is derived from the Pythagorean theorem. For points (2, 8) and (-7, -4), the distance can be calculated as follows:
Subtract the x-coordinates: 2 - (-7) = 9.Subtract the y-coordinates: 8 - (-4) = 12.Square each result: 92 = 81 and 122 = 144.Add the squares together: 81 + 144 = 225.Take the square root of the sum: \\sqrt{225}\ = 15.Therefore, the distance between the points (2, 8) and (-7, -4) is 15 units.
Factor completely x3 + 4x2 + 8x + 32. (x + 4)(x2 + 8) (x − 4)(x2 − 8) (x − 4)(x2 + 8) (x + 4)(x2 − 8)
[tex]\tt x^3+4x^2+8x+32\\\\=x^2(x+4)+8(x+4)\\\\=\boxed{\tt(x+4)(x^2+8)}[/tex]
Answer:
(x+4)(x^2+8)
Step-by-step explanation:
x^3 + 4x^2 + 8x + 32
We will factor by grouping
Factor out an x^2 from the first two terms and an 8 from the last two terms
x^2 (x+4) + 8(x+4)
Now we can factor out an (x+4)
(x+4)(x^2+8)

Let is convert it into standard form of a parabola
[tex]y=x^2-6x+4[/tex]
adding and subtracting 9 in the right hand side of the =
[tex]y=x^2-6x+9-9+4[/tex]
