You multiply by 1.12 to find your answer
Answer: 1.12
To get this answer, you would represent 12% as 0.12 (move the decimal point 2 spots to the left to go from 12.0% to 0.12) then you add on 1 to get 1+0.12 = 1.12
Another way to think about it is to have 100% + 12% = 112%, so the new price is 112% of the old price. For example, if the car was $100 and you increase the price by 12%, then it jumps to $112. Notice how 1.12*(old price) = 1.12*100 = 112 = new price

What is the antiderivative of e^x^2?
Answer: The antiderivative of [tex]e^{x^{2}}[/tex] is [tex]\sqrt{\pi} \sqrt{e^{x^2}-1} +C[/tex].
Explanation:
[tex]I=\int{e^{x^2}dx}\\I^2=\int{e^{x^2}dx}\int{e^{x^2}dx}[/tex]
Using dawson integral.
[tex]I^2=\int{e^{x^2}dx}\int{e^{y^2}dy}[/tex]
[tex]I^2=\int{\int{e^{x^2+y^2}dxdy}}[/tex]
Put [tex]x^2+y^2=r^2[/tex]
[tex]I^2=\int{\int{e^{r^2}rdrd\theta}}[/tex]
[tex]\int_{0}^{2\pi}{d\theta}\int_{0}^{x}{re^{r^2}dr}[/tex]
Use substitution method and sunbstitute [tex]r^2=t[/tex].
[tex]\int_{0}^{2\pi}{d\theta}\int_{0}^{x^2}{\frac{1}{2}e^tdt}[/tex]
[tex]I^2=\frac{1}{2}|\theta|_{0}^{2\pi}|e^t|_{0}^{x^2}\\I^2=\frac{1}{2}(2\pi)(e^{x^2}-1)\\I=\sqrt{\pi}\sqrt{e^{x^2}-1}[/tex].
Therefore, the antiderivative of [tex]e^{x^{2}}[/tex] is [tex]\sqrt{\pi} \sqrt{e^{x^2}-1} +C[/tex].

Audra was drawing a perpendicular bisector of segment ab with a compass . She started with a line segment AB . Then she placed her compass point on A and opened the compass more than halfway to B what’s her next step
To draw a perpendicular bisector, her next step should be to: draw two arcs to the left and right of A and B using the same width of the compass.
What is a Perpendicular Bisector of a Segment?A perpendicular bisector of a segment can be described as a line that divides a segment into two equal parts at right triangle.
Thus, based on the definition of a perpendicular bisector of a segment, for Audra to draw a perpendicular bisector of segment AB, her next step should be to: draw two arcs to the left and right of A and B using the same width of the compass.

7 plus the sum of a number x and 5 write this phrase as an expression
The equation is: 7 + (x + 5)
The expression for '7 plus the sum of a number x and 5' is written as '7 + (x + 5)'.
The phrase '7 plus the sum of a number x and 5' can be written as an algebraic expression. This involves taking the sum of the variable x and the number 5, and then adding 7 to this sum. In mathematical terms, this is expressed as 7 + (x + 5).
Let's break it down step by step:
First, identify the sum: x + 5.
Next, add 7 to the result of this sum.
So, if we were to evaluate this expression for x = 4, we would calculate it as follows:
7 + (4 + 5) = 7 + 9 = 16

Answer:
We have
k^2 - 25f^2 + 5kf - 25f^2 =
k^2 - (5f)^2 + 5f( k - 5f) =
( k - 5f )( k + 5f ) + 5f( k - 5f ) =
( k - 5f )( k + 5f + 5f ) =
( k - 5f )( k + 10f );
Step-by-step explanation:
Answer: The required factored form of the given expression is [tex](k-5f)(k+10f).[/tex]
Step-by-step explanation: We are given to factor the following quadratic expression :
[tex]E=k^2+5kf-50f^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To factor the given expression, we need two integers with sum 5 and product -50 and those two integers are 10 and -5.

graph a function that is undefined
A graph that is undefined has a slope of [tex]x=0[/tex]
Graph the function as usual, but skip the undefined point. You may want to graph the surroundings to see how the function behaves near the undefined point.
Just graph the function as usual, but skip the troublesome point. You may want to graph the surroundings of the said undefined point.
For example, when you're graphing y=1/x, we know that when x=0 the function is undefined, so just skip it. But, you can draw the surroundings of x=0, for example, when x=±1,±0.1,±0.01,±0.001,... and see what happens to the function as it approaches x=0.
This is an example of the plot. As you can see, you just skip over when x=0, but still plot the rest of the domain. You can see that the function behaves erratically near x=0.
Another example: try to plot f(x)=(x2−4)/(x−2). If you plotted it correctly, you should see a 'straight-line', except that it was punctured on the point (2,4), because f(x) wasn't defined for x=2. In this case, you just draw a hollow circle on that point (like: o ), to show that the function is not exactly continuous and there is a hole on point (2,4).

What substitution should be used to rewrite 4x^4-21x^2+20=0 as a quadratic equation
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
Answer:
4y^2 - 21y + 20 = 0
Step-by-step explanation:
As (4x^4 - 21x^2 + 20=0) being a biquadratic equation, meaning it is a 4-degree equation without the terms of degree 1 and 3.
To solve this particular case you only need to replace the variables of degree 4 and 2 for a new variable of degree 2 and 1 and solve it as regular quadratic equation and then undo the change.
* Using a new variable we can rewrite the equation:
Let y be the new variable;
y= x^2, then y^2= x^4
Then we have;
4y^2- 21y+20=0
Solve for y and then find X which will be the roots for the biquadratic equation.

What is y= -1/3x-9 written in standard form
Simplify 1/3x to x/3
y = -x/3 - 9
Add 9 to both sides
y + 9 = -x/3
Multiply both sides by 3
(y + 9) * = -x
Regroup terms
3(y + 9) = -x
Using the formula, rewrite in standard form
Answer: x + 3y = -27
To convert the equation y = -1/3x - 9 to standard form, you need to eliminate the fraction and rearrange the equation. Multiply both sides of the equation by 3 to get 3y = -x - 27. Rearrange the equation to get x + 3y = -27, which is the standard form.
Explanation:The equation y = -1/3x - 9 can be written in standard form as Ax + By = C, where A, B, and C are constants. To write the equation in standard form, we need to eliminate the fraction by multiplying both sides of the equation by 3. This gives us 3y = -x - 27. Rearranging the equation, we get x + 3y = -27, which is the standard form.
