Answer:
300 + 700 = 1000 or One Thousand
Step-by-step explanation:
Lauren wants to buy 3 shirts at $15.00 each. At home, she calculates the total cost as $46.20, using the sales tax rate of 8%. At the store, the cashier tells Lauren the total cost is $48.60. Who is wrong and what mistake did he or she make?
help!! please give explanation

Answer:
Lauren is wrong. She calculated tax on one shirt only.
Step-by-step explanation:
The cashier correctly determined the amount due to be ...
(3 × $15.00) × 1.08 = $48.60
Lauren correctly determined that the tax on one shirt is $15.00 × 0.08 = $1.20, but seemingly failed to realize that the tax on 3 shirts would be 3 times that amount. Lauren made a mistake in computing the tax due.
If the composition of two functions is:
1/x−3
What would be the domain restriction? Describe how you found that answer.
9514 1404 393
Answer:
x ≠ 3
Step-by-step explanation:
In any case, the domain is restricted to values of the variable for which the function is defined. The value 1/0 is not defined, so the variable cannot allow the denominator to be zero. The denominator x-3 will be zero for x=3, so that value of the variable cannot be in the domain.
The domain is all real numbers except x=3.

Additional comments
It is useful to become familiar with the domains of different functions. As we saw above, the reciprocal of 0 is undefined. The square root of a negative number is undefined. The log of a non-positive number is undefined. Trig functions are defined everywhere, but their inverse functions are not. Polynomial functions are defined everywhere, but ratios of polynomials have the same restriction on denominators that we see above.

Find the y-intercept of the parabola y=x^2
Hello!
The y intercept of the parabola is when one of it's function's hits/intersects the y axis. The y intercept of the parabola y = x^2 is (0,0).
You may be wondering where is that, and why is it there. Y = x^2 is a parent function.
Check the image below for better explanation from me.
(0,0) = y - intercept

Is the quotient of square root of 10 and 5 a rational number? Explain.
Answer:
No, it is irrational.
Explanation-
The quotient of √10 and 5 is equal to which equals 0.6245553... The number goes on and on forever with no determinable pattern (i.e. the decimal 0.234234234... although the decimal goes on forever, the 234 repeats over and over) -hope this helped.
Answer:
No
Step-by-step explanation:
the square root of 10 is irrational so its irrational

Part C
In the same way that other functions can be combined, a series of transformations can be combined into a single function. For example,
this statement for the function S shows one way to represent the rotation of a point 270° counterclockwise about the origin followed by a
translation 3 units to the left and 1 unit up: S(270, 0)/<-3,1>(x, y) = (y - 3, -x + 1).
Write a function to represent each series of transformations:
• rotation of 90 degrees counterclockwise about the origin, point o, then a reflection across the x-axis
• reflection across the y-axis, then a translation a units to the right and b units up
• translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection
across the y-axis
In geometry, transformations are used to move points from one position to another. The functions to represent the transformations are as follows:
[tex]S(90,0)/R_x(x,y) = (-y,-x)[/tex] .[tex]R_y/<a,b>(x,y) = (-x-a,y+b)[/tex].[tex]<a,b>(x,y)/S(180,0)/R_y = (x+a,-y-a)[/tex](a) Rotation of 90 degrees counterclockwise about the origin, point o, then a reflection across the x-axis
When a point is rotated [tex]90^o[/tex] counterclockwise, the rule is:
[tex](x,y) \to (-y,x)[/tex]
The rule of reflection across the x-axis is:
[tex](x,y) \to (x,-y)[/tex]
So, the combined transformation is:
[tex](-y,x) \to (-y,-x)[/tex]
Hence, the function that represents the transformation is:
[tex]S(90,0)/R_x(x,y) = (-y,-x)[/tex]
(b) Reflection across the y-axis, then a translation a units to the right and b units up
The rule of reflection across the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
The rule of translation, a units right and b units up is:
[tex](x,y) \to (x + a,y+b)[/tex]
So, the combined transformation is:
[tex](-x,y) \to (-x - a,y+b)[/tex]
Hence, the function that represents the transformation is:
[tex]R_y/<a,b>(x,y) = (-x-a,y+b)[/tex]
(c) Translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis
The rule of translation, a units right and b units up is:
[tex](x,y) \to (x + a,y+b)[/tex]
When a point is rotated [tex]180^o[/tex] counterclockwise, the rule is:
[tex](x,y) \to (-x,-y)[/tex]
The combined transformation at this point is:
[tex](x + a, y + a) \to (-x-a,-y-a)[/tex]
The rule of reflection across the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
So, the overall transformation is:
[tex](-x-a,-y-a) \to (x+a,-y-a)[/tex]
Hence, the function that represents the transformation is:
[tex]<a,b>(x,y)/S(180,0)/R_y = (x+a,-y-a)[/tex]

Average rate of change please helpp
The average rate of change over the interval [-9, -3] is
[tex]\dfrac{f(-3) - f(-9)}{-3 - (-9)}[/tex]
That is, it's the ratio between the change in the function value over the length of the interval. Judging by the plot, we have f (-9) = 6 and f (-3) = -3. So the average rate of change is
[tex]\dfrac{f(-3) - f(-9)}{-3 - (-9)} = \dfrac{-3 - 6}{-3 + 9} = -\dfrac96 = \boxed{-\dfrac32}[/tex]
