Find the inverse of k(x)=x²-3. Define the restrictions to the domain.
Answer: The inverse of the function k(x)=x²-3 is k^(-1)(x)=±√(x+3). The domain restrictions for the inverse are x≥-3, since the square root is only defined for non-negative values.
The inverse of a function is the reflection of the original function over the line y=x. To find the inverse of k(x)=x²-3, we first swap the x and y variables: y=x²-3. Then, we solve for x: x=±√(y+3). This gives us the inverse function k^(-1)(x)=±√(x+3).
However, it is important to note that the square root function is only defined for non-negative values. Therefore, we must restrict the domain of the inverse function to x≥-3. This means that the inverse function can only be applied to input values that are greater than or equal to -3. For values less than -3, the inverse function is undefined.
Step-by-step explanation:
Answer:
Inverse function: [tex]\pm \sqrt{x + 3}[/tex]
Domain: [tex]x \ge -3[/tex]
Step-by-step explanation:
[tex]k(x) = x^2-3[/tex]
To find the inverse, set y = k(x)
==> y = x² - 3
Swap x and y
x = y² - 3
Add 3 to both sides
x + 3 = y²
y² = x + 3
[tex]y = \pm \sqrt{x + 3}[/tex]
or, in other words:
[tex]y = \sqrt{x +3} \:\;and\; y = -\sqrt{x + 3}[/tex] are the two solutions
Replace Swap x and y again to get the inverse as a function of x
[tex]k^{-1}(x) = \sqrt{x+3},\:-\sqrt{x+3}[/tex]
Since square roots of negative numbers are not defined, the term under the square root must be ≥ 0
x + 3 ≥ 0
==> x ≥ -3
There is no restriction on the upper bound it can go upto infinity

Line segment xy is dilated to create line segment x'y' using point t as the center of dilation. Point t is the center of dilation. Line segment x y is dilated to create shorter line segment x prime y prime. The length of t x prime is 6 and the length of t y prime is 9. The length of x x prime is 2. What is yt?.
Given that point T is the center of dilation, we know that the length of line segments TX' and TY' are proportional to the length of line segments TX and TY, respectively.
We can express this as:
TX' = k * TX
TY' = k * TY
where k is the scale factor.
We are given the lengths of TX' and TY':
TX' = 6
TY' = 9
So, we can solve for k:
9 / k = 6
k = 9 / 6 = 3 / 2
Now that we know the value of k, we can find TY:
TY = TY' / k = 9 / (3 / 2) = 6 * (3 / 2) = 9
Next, we are given the length of XX':
XX' = 2
And using the dilation formula, we can find XX:
XX = XX' / k = 2 / (3 / 2) = 2 * (2 / 3)
Finally, we can find TX by using the Pythagorean theorem:
TX^2 = TY^2 + XX^2
TX^2 = 9^2 + (2 * (2 / 3))^2
TX^2 = 81 + (4 / 3)^2
TX^2 = 81 + 16 / 9
TX^2 = 81 + 16 / 9
TX = √(81 + 16 / 9) = √(81 + 16 * 9 / 9) = √(81 + 16) = √97
So, TY = 9 and TX = √97. Therefore, YT = TY - TY' = 9 - 9 = 0.

88
Answer:
28
Step-by-step explanation:
The slope of a line represents the rate of change between two variables. In the case of Superior Segway Tours, the cost of the tour is changing as the number of hours for the tour changes. The rate of change can be calculated by dividing the change in the dependent variable (cost) by the change in the independent variable (hours). In this case, the slope is $28 per hour. This means that for every hour that is added to the tour, the cost will increase by $28.
The slope of this situation can be represented as the change in cost (y-axis) per unit change in time (x-axis). The slope in this case would be $28 per hour.
What is the area of triangle []
ABC
?
Triangle ABC. Angle A = 60 degrees. Angles B = 60 degrees. Angle D = 90 degrees. BC = 12.
Select the correct choice.
In a triangle ABC, angle B=90, angle C=60, angle A=30 and BC=12cm. The area of the triangle is 144 * (√3/2) sq cm
How did we get the value?In a right triangle with a 90 degree angle, the length of the side opposite the 90 degree angle is the height, and the length of the other two sides form the base. If angle C = 60 degrees, then angle A = 90 - 60 = 30 degrees.
If BC = 12 cm, then the height AC is equal to AB * sin(30) = 12 * (√3/2).
The area of the triangle is equal to (1/2) * base * height = (1/2) * 12 * (12 * (√3/2)) = (12 * 12 * (√3/2))/2 = 144 * (√3/2) sq cm

Assume you have a balance of $1200 on a credit card with an APR of 18%. You start
making monthly payments of $300 but at the same time charge an additional $75 a
month. Assuming that interest for a given month is based on the balance for the previous
month, how long does it take you to pay off the credit card debt?
Assuming that interest for a given month is based on the balance for the previous month, it will take 6 months to pay off the credit card debt of $1,200 when making a net payment of $225.
How is the period determined?An online finance calculator can determine the period for a compound interest system.
The length of payment uses the beginning credit card balance of $1,200 and the net payment of $225 (since a monthly payment of $300 is made when an additional charge of $75 is withdrawn from the card).
I/Y (Interest per year) = 18%
PV (Present Value) = $1,200
PMT (Periodic Payment) = $-225 ($300 - $75)
FV (Future Value) = $0
Results:
Period (N #) = 5.6
Sum of all periodic payments = $-1,260.08
Total Interest = $60.08
Thus, within six months you can pay off the credit card debt.

What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.
Given, You have an inheritance of $100,000 from your grandparents, you must invest the money in a mutual fund until you are 21 years old, which will pay an annual interest rate of r% compounded continuously.
From the general formula of compound interest:
A = Pe^rt,
where P is the principal balance,
r is the interest rate,
n is the number of times interest is compounded annually,
t is the number of years
In our case,
P = 100,000
t = 21 - 17 = 4
n = 12 for compounded continuously
thus,
A = 100,000(2.71828)^r4
For the value of r = 7
A = 100,000.00(2.71828)^(0.07)(4)
A = $132,312.98

These worksheets also come with self-explanatory answer-keys for instant doubt clarification and self-learning.
Using basic arithmetic operations, the missing terms are a) 7/5 and b) 19/14.
There are four basic arithmetic operations which are addition, subtraction, multiplication, and division. These operations can be applied to whole numbers and fractions.
a) 14/16 x 8/7= y x 5/7
In order to solve for y, the numerator and denominator on LHS are simplified and multiplied:
14/16 x 8/7= 7/8 x 8/7 = (7 x 8)/(8 x 7)
As there are same numbers in both numerator and denominator, they are cancelled:
(7 x 8)/(8 x 7)=1
Hence,
1= y x 5/7
Multiply both side by 7/5
7/5 x 1= y x 5/7 x 7/5
y= 7/5
b) 1/2+ 4/7= y -2/7
In order to solve for y, add the fraction on LHS:
1/2+ 4/7= ((7 x 1)+(4 x 2))/((2 x 7)) = (7+8)/14=15/14
Hence,
15/14= y -2/7
Add 2/7 to both sides:
15/14+ 2/7= y -2/7 + 2/7
y = (15+4)/14=19/14

The concepts of projecting a vector onto another and rejecting a vector from another can be applied to the concepts of projecting a vector onto a plane and rejecting a vector from a plane for a three-dimensional inner product space.
A vector's orthogonal projection on a plane is the vector's projection on that plane. A vector is rejected from a plane when it is projected in an orthogonal direction on a straight line. They're both vectors. The first is orthogonal to the plane, while the second is parallel.

Now , the value of f ( x ) is given as
f ( x ) = √x - 5 be equation (1)
On simplifying the equation , we get
y = √x - 5
To calculate the inverse of the function , solve for x , we get
Adding 5 on both sides of the equation , we get
√x = y + 5
Taking the square on both side of the equation , we get
x = ( y + 5 )²
Substitute the value of x = f⁻¹ ( x ) and y = x , we get
f⁻¹ ( x ) = ( x + 5 )²
And , the domain of the function is [ 0 , ∝ ]
Hence , the function is f⁻¹ ( x ) = ( x + 5 )²
