0.3 less than 15 or 0.3 more than 15 would be the acceptable range of values.
Consequently, based on the provided data, the permitted value range is
between 14.7 and 15.3
How to calculate the range between the given no.s ?The difference between the lowest and highest values in a list or set is known as the range. Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest. The range of the list is provided in the response.
so we know:
To find the range of values that can are permitted to vary by 2% of 15, first,
find the value of 2% of 15:
2/100*15=30/100=0.3
The permitted range of values would be 0.3 less than 15 or 0.3 greater than 15.
hence the values will be:
15+0.3 or 15-0.3
range=14.7 to 15.3
Therefore the range of the allowable values according to the given data is

What is the sequence of transformations that maps ABC to A’B’C’
Step 1:
A. Reflect across the line Y=X
B. Reflect across the x-axis
C. Rotate 90° clockwise about the origin.
D. Rotate 180° about the origin
Step 2:
A. Translate 6 units up
B. Translate 5 units up
C. Reflect across the line y=x
D. Reflect across the x-axis
The sequence of transformations that maps ∆ABC to ∆A′B′C′ is a reflection across the line y = x followed by a translation 10 units right and 4 units up.
What is meant by the sequence of transformations?A certain order of transformational occurrences is referred to as a transformational sequence. This indicates that more than one transformation is handled by a series of transformations, and the order in which they happen is important.
We are given that ΔA'B'C' exists formed after a sequence of transformations applied to ΔABC.
The first exists a reflection across a line and the second exists a translation.
The coordinates of point C exist (-4, -2). After reflection from the line y = x, the coordinates become (2, -4).
Also, the coordinates of point C' are (12, 0).
So, to get point C' from point C, we should add 10 units to the x-coordinate and 4 units to the y-coordinate.
The translation of 10 units right and 4 units up.
Therefore, the complete transformation is
The sequence of transformations that maps ∆ABC to ∆A′B′C′ is a reflection across the line y = x followed by a translation 10 units right and 4 units up.

What is the solution to the linear-quadratic system of equations.
The solution to the linear-quadratic system of equations are: [tex]\begin{pmatrix}x=1,\:&y=3\\ x=-5,\:&y=-3\end{pmatrix}[/tex].
Quadratic Function
The Standard form for a quadratic equation is ax²+ bx + c=0, where: a, b and c are your respective coefficients. In the quadratic function, the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.
To solve a quadratic function, you should find the discriminant: D=b²-4ac and then use this variable in the formula: [tex]x=\frac{-b\±\sqrt{\Delta} }{2a}[/tex].
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=4x+3. Where:
m= the slope. It can be calculated for Δy/Δx .
b= the constant term that represents the y-intercept.
The question asks the solution of the system the following equations
y=x²+5x-3 (1)
y=2+x (2)
Firstly, you should subtract equation 1 and 2, as result, you have
y-y= x²+5x-3 -(2+x)
y-y= x²+5x-3 -2 -x
0= x² +4x -5
After that for finding x, you should solve the equation x² +4x -5=0. Then,
D=b²-4ac
D= 4²-4*1*(-5)
D=16+20
d=36
Thus,
[tex]x=\frac{-b\±\sqrt{\Delta} }{2a}= \frac{-4\±\sqrt{36} }{2*1}= \frac{-4\±\ 6 }{2}[/tex]. Therefore
x1=(-4-6)/2= -10/2=-5

Given ^PRS = ^CFH, find the values of x, y, and z.
Answer:
x = 23, y = 7, z = 11
Step-by-step explanation:
Since triangle PRS is congruent to triangle CFH,
PS = CH = 39
2x - 7 = 39
2x = 46
x = 23
Angle PRS = Angle CFH = 90°
13y - 1 = 90
13y = 91
y = 7
Sum of angles in a triangle add up to 180°.
Angle CHF = 180 - 90 - 28 = 62°
6z - 4 = 62
6z = 66
z = 11
For the function y = x² - 8x + 16, work out the coordinates of the y-
intercept.
What’s the value of x
Using the rules of complementary angles we calculate that the value of x is 12° .
Pairs of complementary angles have measures which are one right angle.
The non-shared sides of two adjacent complementary angles form a right angle. Given that the sum of a triangle's internal angles is 180 degrees and the right angle alone accounts for 90 degrees, the two sharp angles of a right triangle are complimentary in Euclidean geometry.The Latin word complementum, from which the English word complement is derived, is related to the verb complere, which means "to full up." A right angle is created when an acute angle is "filled up" by its opposite.The complement of the angle describes the distinction between an angle and a straight angle.The two given angles are 29° and ( 5x + 1 )°.
There are a pair of complementary angles.
Therefore 29° + ( 5x + 1 )° = 90 °
or, 5x + 30° = 90 °
or, 5x = 60
or, x = 12°
Therefore using the rules of complementary angles we calculate the value of x is 12°.

For the given quadratic function, we have that:
The x-intercepts are x = 0 and x = -2.The y-intercept is of y = 0.The zeros are x = 0 and x = -2.f(-4) = -16.f(x) = 2 when x = -1.What are the intercepts of the function?The x-intercepts of the function are the same as the zeros, that is, the values of x for which f(x) = 0.
For this problem, the function is defined as follows:
f(x) = -2x² - 4x.
Hence the x-intercepts are given as follows:
-2x² - 4x = 0
2x² + 4x = 0
2x(x + 2) = 0.
Hence:
2x = 0 -> x = 0.x + 2 = 0 -> x = -2.What is f(-4)?The numeric value at x = -4 is calculated replacing each instance of x by -4, hence:
f(-4) = -2(-4)² - 4(-4) = -16.
When is f(x) = 2?We have to solve for x as follows:
-2x² - 4x = 2
2x² + 4x + 2 = 0
x² + 2x + 1 = 0
(x + 1)² = 0.

After making the swim team, Farrah purchased a swimsuit, a swim cap, and a pair of goggles. The swimsuit was twice as much as the goggles, and the swim cap was half the price of the goggles. If the total cost of the items was $59.50, what was the price of the swimsuit?
By using linear equation, When the swimsuit was twice as much as the goggles and the swim cap was half the price of the goggles. If the total cost of the items was $59.50, then the price of the swimsuit is $34
The total cost of the items = $59.50
Consider the cost of goggles = 2x
The swimsuit was twice as much as the goggles
The cost of the swimsuit = 4x
Swim cap was half the price of the goggles
The cost of the swim cap = x
Then the price of the items = The cost of goggles + The cost of the swimsuit + The cost of the swim cap
Substitute the values in the equation
2x + 4x + x = 59.50
7x = 59.50
x = $8.5
The cost of the swimsuit = 4x
= 4×8.5
= $34

in the theory of learning, the rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized. assume that the rate at which material is forgotten is proportional to the amount memorized. suppose m denotes the total amount of a subject to be memorized and a(t) is the amount memorized in time t > 0. determine a differential equation for the amount a(t) when forgetfulness is take
The differential equation of the amount of a subject memorized in time t > 0 is k. a(t) + da(t)/dt = km, where k is a constant representing the rate at which a subject is memorized.
Translate the given word problem into an algebraic expression.
Let m be the total amount of a subject to be memorized.
Let a(t) be the amount memorized in time t > 0.
Let c(t) be the amount that is left to be memorized in time t > 0.
Then,
c(t) = m - a(t)
From the problem, the rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized. It means:
da(t)/dt = k. c(t), where k is a constant
da(t)/dt = k. (m - a(t))
k. a(t) + da(t)/dt = km
