Explain in writing how the graph of the function h(x) = -|x-1| +4 is related to the graph of oneof the six basic functions. Sketch a graph of h(x). (6 points
Notice that the expression for h(x) uses an absolute value. The absolute value is the basic function related to h(x).
Recall the following function transformations:
Horizontal shift by c units:
[tex]f(x)\rightarrow f(x-c)[/tex]Vertical shift by c units:
[tex]f(x)\rightarrow f(x)+c[/tex]Reflection across the X axis:
[tex]f(x)\rightarrow-f(x)[/tex]Starting with the absolute value function, notice that the function h can be obtained by applying a reflection across the X-axis, a horizontal shift by 1 unit and a vertical shift by 4 units:
[tex]undefined[/tex]I have no idea how to solve this problem, could someone help me?△ABC∼△XYZ. Find the values of x and b (side lengths).
The symbol ∼ denotes similarity, that is, the triangles ABC and XYZ are similar. When two triangles are similar, they have the same shape but not necessarily the same size and their corresponding angles are the same. In turn, the corresponding sides of two corresponding triangles are in the same ratio. Graphically,
[tex]\frac{a}{a^{\prime}}=\frac{b}{b^{\prime}}=\frac{c}{c^{\prime}}[/tex]So to find x in the small triangle, you have
[tex]\begin{gathered} \frac{15}{10}=\frac{9}{x} \\ \text{ Multiply by x on both sides of the equation} \\ \frac{15}{10}\cdot x=\frac{9}{x}\cdot x \\ \frac{15}{10}x=9 \\ \text{ Multiply by }\frac{10}{15}\text{ on both sides of the equation} \\ \frac{10}{15}\cdot\frac{15}{10}x=9\cdot\frac{10}{15} \\ x=6 \end{gathered}[/tex]Finally, to find b in the large triangle, you have
[tex]\begin{gathered} \frac{15}{10}=\frac{b}{8} \\ \text{ Multiply by 8 on both sides of the equation} \\ \frac{15}{10}\cdot8=\frac{b}{8}\cdot8 \\ 12=b \end{gathered}[/tex]Therefore, the lengths of the sides x and b are
[tex]\begin{gathered} x=6 \\ b=12 \end{gathered}[/tex]Find the area of the figure below
Answer:
Step-by-step explanation:
b/c we can fairly say, that the parallelgram is also a rectangle of size 24 x 11, we can just solve that area
24*11= 264
We can see, this is a parallelogram.
The formula to calculate the area of a parallelogram is b x h, where b is base and h is height.
Given that base = 24 in, height = 11 in, we can calculate the area as : 24 x 11 = 264 in2.
(2)/(3)x-1=9-(1)/(6)x
For the given equation the value of x is, x = 12.
What is solving an equation?
Finding an equation's solutions, which are values (numbers, functions, sets, etc.) that satisfy the equation's condition and often consist of two expressions connected by an equals sign, is known as solving an equation in mathematics. One or more variables are identified as unknowns when looking for a solution.
Consider, the given equation[tex]\frac{2}{3}x - 1=9-\frac{1}{6}x[/tex]
Add 1 on both sides,
[tex]\frac{2}{3}x -1+1 = 9-\frac{1}{6}x+1\\ \frac{2}{3}x=10-\frac{1}{6}x[/tex]
Add 1/6(x) to both sides,
[tex]\frac{2}{3}x + \frac{1}{6}x = 10 - \frac{1}{6}x+\frac{1}{6}x\\ \frac{5}{6}x = 10[/tex]
Multiply both sides by 6/5
[tex]\frac{5}{6}x (\frac{6}{5}) = 10(\frac{6}{5}) \\ x = 12[/tex]
Hence, the value of x is, x = 12.

Richard says that the rule (x,y)--> (0.2x,y) describes a horizontal stretch because only the x-coordinates are affected by the real. Is Richard correct? Why or why not?
Although it is true that only the x-axis is affected, that is, on the horizontal, when multiplying by a number less than 1, there would not be a stretch but a narrowing.
That is, the horizontal part would be smaller, which contradicts what Richard says.
Given the equations and the table below, what is the first x-value when the y-value of equation 2 is greater than the y-value of equation 1 after the functions first intersect?Equation 1: f(x)=5x^3Equation 2: f(x)=2x+3A: x=14B: x=7C: x=17D: x=12
From what I explained in the session before, the x value must be between 10 and 15, so only 2 options are viable, 14 and 12. Let's evaluate each of them
[tex]\begin{gathered} f(x)=5x^3 \\ f(12)=5(12)^3 \\ f(12)=5(1728) \\ f(12)=8640 \\ \\ f(x)=2^x+3 \\ f(12)=2^{(12)}+3 \\ f(12)=4096\text{ +3 = 4099} \end{gathered}[/tex]So, 12 is not the answer. Let's evaluate 14
[tex]\begin{gathered} f(x)=5x^3 \\ f(14)=5(14)^3 \\ f(14)=5(2744) \\ f(14)=13720 \\ \\ f(x)=2^x+3 \\ f(14)=2^{14}+3 \\ f(14)=16384+3 \\ f(14)=16387 \end{gathered}[/tex]So, x = 14 is the correct answer
A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.
Answer:
perimeter is 7.5 units
Step-by-step explanation:
the sides of the regular polygon are the same length , then
5x - 6 = 3)x - 1)
5x - 6 = 3x - 3 ( subtract 3x from both sides )
2x - 6 = - 3 ( add 6 to both sides )
2x = 3 ( divide both sides by 2 )
x = 3 ÷ 2 = 1.5
then length of one side is
5x - 6 = 5(1.5) - 6 = 7.5 - 6 = 1.5 units
then perimeter = 5 × 1.5 = 7.5 units

3. Make sure to include the measurement in your final answer.
Using the perimeter concept, the measures are given as follows:
a) Perimeter when the missing box is of -7: -6x² + 8x + 4.
b) Coefficient missing when the perimeter is of 5x² + 8x + 4: a = 4.
c) Perimeter from part B when x = 3: 73 inches.
How to obtain the perimeter of a figure?The perimeter of a figure is obtained by the sum of their outer side lengths.
For this shape, these lengths are given as follows:
3x.x² + 5.ax² + x.4x - 1.With a missing coefficient of a = -7, we have that:
ax² + x = -7x² + x.
Hence the perimeter is:
3x + x² + 5 - 7x² + x + 4x - 1 = -6x² + 8x + 4.
In symbolic terms, the perimeter is:
(1 + a)x² + 8x + 4.
When the perimeter is of 5x²+8x + 4, the coefficient is:
1 + a = 5
a = 5 - 1
a = 4.
When x = 3 and a = 4, the perimeter is given as follows:
P = 5(3)² + 8(3) + 4 = 73 inches.

You flip a coin and then spin this spinner. a) Determine whether these events are Independent or Dependent. Write I on D b) Find the probability that the coin lands tails-up and the spinner Yands on a I Write as a reduced fraction (numerator/denominator). 1
SOLUTION
Dependent events influence the probability of other events or their probability of occurring is affected by other events. Independent events do not affect one another and do not increase or decrease the probability of another event happening.
PART A
Since the flip of a coin would not affect the spin of the spinner, therefore these events are independent events.
The answer is 'I'
PART B
To find the probability that the coin lands tails-up and the spinner lands on 1, we would need to find the probability of getting a tail, then we find the probability of getting a 1
Therefore,
[tex]\text{Probaility}=\frac{no\text{ of favourable outcomes}}{\text{Total possible outcomes}}[/tex]When we flip a coin, the favourable outcome for a tail is 1 since a tail can only occur once in one flip. The total possible outcomes are 2, since we can have either a tail or head occurring in one flip.
Then,
[tex]Pr(\text{Tail)}=\frac{1}{2}[/tex]When we spin the spinner, the favourable outcome for one is 1, since we have only one slot for one on the spinner. The total possible outcome is 4 since we have 4 different number
slots on the spinner.
Then,
[tex]Pr(1)=\frac{1}{4}[/tex]To get the probability of getting a tail, then we find the probability of getting a 1 we multiply the probability of getting a one on the spinner and a tail on the flip.

Evaluate inverse functions The graph of y= h(x) is a line segment joining the points (-7,-5) and (-1,-2) Drag the endpoints of the segment below to graph y=h^-1(x)
When we have an inverse function, the domain and range are switched.
All x-coordinates become y-coordinates and vice-versa.
So, if the point (-7, -5) is a solution of h(x), the point (-5, -7) is a solution of h^-1(x)
If the point (-1, -2) is a solution of h(x), the point (-2, -1) is a solution of h^-1(x).

The rocket arrives at its most extreme level at 1.5 seconds after send-off will be 39 feet.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
A toy rocket is shot upward up high from a take-off platform 3 feet over the ground with an underlying speed of 48 feet each second. The level h, in feet, of the rocket over the ground at t seconds after send-off is given by the capability h(t) = - 16t² + 48t + 3.
Differentiate the function and put it equal to zero.
h'(t) = 0
-32t + 48 = 0
32t = 48
t = 1.5 seconds
Then the maximum height is given as,
h(1.5) = - 16(1.5)² + 48(1.5) + 3
h(1.5) = 39 feet
The rocket reaches its maximum height at 1.5 seconds after launch will be 39 feet.

Complete the two-way frequency table below, which shows the relationship between students who enroll in advanced algebra and physics in
particular high school. From a sample of 40 students, it is found that 29 are taking algebra, 14 are taking physics, and 5 are enrolled in both. How
many students are enrolled in either algebra physics?
By making use of Set Theory, we calculate that a total of 38 students are enrolled in either physics or algebra.
Number of students taking algebra n(A)= 29
Number of students taking physics n(B)= 14
Number of students taking both subjects n(A∩B)= 5
So, the number of students taking either physics or algebra will be the union of sets i.e. n(A∪B)
The union of two sets is a set containing all elements that are in A or in B (possibly both).
As we know,
n(A∪B) = n(A) + n(B) - n(A∩B)
n(A∪B) = 29 + 14 - 5
n(A∪B) = 38
Therefore, A total of 38 students are enrolled in either physics or algebra.
