At first let us draw a sketch to show the position of the given angle
Find the area of a square tile which has a width of 3x - 5
Answer:
[tex]9x^2 - 30x + 25[/tex]
Step-by-step explanation:
To solve for area, multiply the width times the height. In this case, since the shape is a square, the width is the same as the height. So, multiplying 3x - 5 times 3x - 5 should give us the area.
[tex](3x-5)(3x-5)\\(3x)(3x) + (3x)(-5) + (-5)(3x) + (-5)(-5)\\9x^2 - 15x - 15x + 25\\9x^2 - 30x + 25[/tex]

10. Higher Order Thinking Winston compares the heights of two plants
to see which plant grows more per day. The table shows the height
of Plant 1, in centimeters, over 5 days. The graph shows the height
of Plant 2, in centimeters, over 10 days. Winston says that since
Plant 1 grows 6 cm per day and Plant 2 grows 4 cm per day,
Plant 1 grows more per day.
Plant 1
Days

Height (cm) 6
a. Do you agree with Winston? Explain your response.

b. What error might Winston have made?
Answers to both subparts are shown:
Although Plant 2 clearly grew 2 cm per day as per the graph, Plant 1 still outgrew Plant 2 by 4 cm.Winston's claim that Plant 2 grows 4 cm per day is false, as shown by the graph, which contradicts Winston's claim, and Plant 2 actually grows 2 cm per day.What is a graph?The relationship between lines and points is described by a graph, which is a mathematical representation of a network. A graph is made up of some points and connecting lines. It doesn't matter how long the lines are or where the points are located. A node is a name for each element in a graph.So, (A) The given statement of Winston is partially correct.
In the graph, we can clearly see that Plant 2 grew 2 cm per day, but still, Plant 1 grows more than plant 2 by 4 cm.(B) Error in Winston's statement:
From the above part, we know that the error is Winston's statement that Plant 2 grows 2 cm per day, but according to the graph Plant, 2 grows by 2 cm per day.Therefore, answers to both subparts are shown:
Although Plant 2 clearly grew 2 cm per day as per the graph, Plant 1 still outgrew Plant 2 by 4 cm.Winston's claim that Plant 2 grows 4 cm per day is false, as shown by the graph, which contradicts Winston's claim, and Plant 2 actually grows 2 cm per day.Know more about graphs here:

Answer
The cost of 1 and (1/4) pounds of raspberries is $10.
Explanation
Anyeny bought (3/4) pounds of raspberries for $6.
What is the cost of 1 and (1/4) pounds of raspberries.
[tex]1\frac{1}{4}=\text{ }\frac{5}{4}[/tex]
(3/4) pounds = $6
(5/4) pounds = x dollars
Creatin a mathematical relation by cross multiplying
(3/4) × x = (5/4) × 6
[tex]\begin{gathered} \frac{3}{4}\times x=\frac{5}{4}\times6 \\ \frac{3x}{4}=\text{ }\frac{30}{4} \\ \text{Cross multiply} \\ 3x\times4=30\times4 \\ 12x=\text{ 120} \\ \text{Divide both sides by 12} \\ \frac{12x}{12}=\frac{120}{12} \\ x=10 \end{gathered}[/tex]Hence, the cost of 1 and (1/4) pounds of raspberries is $10.

The perimeter of the figure below is 60.7 ft. Find the length of the missing side. 7.2 ft 4.1 ft 4.1 ft 4.1 ft 4.1 ft 12.8 ft ? 1.9 ft 1.9 ft 7.2 ft (Note: diagram is NOT to scale)
we know that
The perimeter of the figure is equal to the sum of its length sides
so
P=7.2(2)+4.1(2)+4.1(2)+12.8+1.9(2)+x
Combine like terms
P=47.4+x
Remember that
P=60.7 ft
substitute
60.7=47.4+x
x=60.7-47.4
x=13.3 ft
therefore
the answer is
13.3 ft2) The graph represents the cost of a medical treatment, in dollars, as a function of time, d, in decades since 1978.
It is said that the expression 150(1.8225) ଷrepresents the cost of medical treatment sometime after
1978.
a) Which year does it represent?
b) What would be the medical cost in 1998?
c) If this trend continues, what are the medical costs in 2022?
Since 1978, the graph shows the dollar cost of a medical procedure as a function of time, d. In 1993 year does it represent.
The cost of treatment when d = 1 is $273
Given that,
Since 1978, the graph shows the dollar cost of a medical procedure as a function of time, d.
We have to find in which year does it represent.
Let the equation be
y=150×[tex]e^{at}[/tex]
Where t is the time for year
According to the figure,
y pass (0.5,202.50)
We get,
202.5=150×[tex]e^{0.5a}[/tex]
[tex]e^{0.5a}[/tex]=1.35
Now,
150×(1.35)³=150×[tex](e^{0.5a})^{3}[/tex]
150×(1.35)³=150×[tex]e^{1.5a}[/tex]
1.5 is for 15 years.
1978+15=1993.
Therefore, in 1993 year does it represent.
The graph represents an exponential function:
[tex]$$y=a b^x$$[/tex]
When (x, y)=(0,150), the equation becomes
[tex]$$\begin{aligned}&150=a b^0 \\&a=150\end{aligned}$$[/tex]
When (x, y)=(0.5,202.5), the equation becomes [tex]$202.5=a b^{0.5}$[/tex]
Substitute 150 for a
[tex]$$202.5=150 b^{0.5}$$[/tex]
Divide both sides by 150
[tex]$$1.35=b^{0.5}$$[/tex]
Square both sides
b=1.82
So, the equation of the graph is:
y=150 * 1.82^x
When x=1, we have:
[tex]$$\begin{aligned}&y=150 * 1.82^1 \\&y=273\end{aligned}$$[/tex]
Hence, the cost of treatment when d=1 is [tex]$\$ 273$[/tex].

what is the slope.example answer:m=1
The slope of the given line 2 / 3
What is a slope ?Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).
The given graph indicates that the two points are :
A( 3 , 0 ) and B (0 , -2 )
Thus the slope can be given by the formula mentioned below :
[tex]\frac{y_{2}- y_{1} }{x_{2}- x_{1} }[/tex]
this means - 2 - 0/ 0 - 3
= - 2/ -3

The area of the triangle below is 60 in2. What is the perimeter?
Answer:
P = 63 inches
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
here b = 2x - 6 , h = 4 and A = 60 , then
[tex]\frac{1}{2}[/tex] × 4 ×(2x - 6) = 60
2(2x - 6) = 60 ( divide both sides by 2 )
2x - 6 = 30 ( add 6 to both sides )
2x = 36 ( divide both sides by 2 )
x = 18
2x - 6 = 2(18) - 6 = 36 - 6 = 30
perimeter (P) is the sum of the 3 sides , so
P = 18 + 30 + 15 = 63 inches

The symbols '>' and '<' have an open dot when displayed on the number line.
Why do the prescribed symbols have an open dot and not a closed dot?
The '>' and '<' symbols have an open dot on the number line because the number that succeeds the symbol is not considered while plotting the range of values that would satisfy any given equation.
Moreover, if a closed dot is put in there, the whole solution becomes incorrect as an unwanted value gets included in the range of values of the domain of the given function.
