using a ruler and a pair of compass only construct triangle XYZ such that XY=9.5
<YXZ=60
Answer: 22.5
Explanation: from P the radii of length r are perpendicular to xz, xy, and yz and all the same.
if draw it with your compass your see a certain symmetry
call the tangent point on xz Q and the one on xy S
triangle XQP is congruent to XSP and is a right triangle
the two angles at x are 22.5 degrees
so PQ = PS = 4 tan 22.5

What is a Box Plot?A box plot shows the five-number summary of a data distribution which includes:
Minimum valueMaximum valueMedianUpper quartile (Q3)Lower quartile (Q1)To create a a box plot for the data, we need to state out each data point given in the dot plot, which are:
2.3, 2.4, 2.4, 2.5, 2.6, 2.6, 2.7, 2.7, 2.8, 2.8
The five-number summary of the data points stated above would be:
Minimum value - 2.3Maximum value - 2.8Median - 2.6Upper quartile (Q3) - 2.7Lower quartile (Q1) - 2.4Therefore, the box plot showing the five-number summary of the data in the dot plot is shown in the image attached below (see attachment).

Please help me! This is finding slope btw
Step-by-step explanation:
for number 8. The slope is -3 because the standard form equation is y=mx+c. And we know that m represents your slope.
Hence why it is -3.

Jimmy is having a birthday party at the zoo. The zoio has a fixed fee for birthday parties, plus a fee per person. Jimmy is told the total charge for ten people,including himself, would be 97. 50 and the total charge for 20 people, including himself would be $175. Determine the independent and dependent variable
Answer:
independent: number of personsdependent: chargesStep-by-step explanation:
The scenario describes charges as being dependent on the number of persons. That means the independent variable is the number of persons, and the dependent variable is the total charge.
(When we say "A depends on B", that automatically defines A as being the dependent variable, and B the independent variable.)
__
Additional comment
Perhaps you also want to know the relationship between the charges c and the number of persons p. That will be ...
c = 7.80p +19.00
You know the rate per person from the fact that adding 10 people to the party raises the cost by $78. Then the 10-person charge includes a fixed fee of $97 -78 = $19.
calculate the area of the figure below
Answer:
164 cm²
Step-by-step explanation:
Take the 2 shapes and find the areas
Triangle area = (bh)/2
13 × 8 × 0.5 = 52
Rectangle area = 16 × 7 = 112
Add up the areas
112 + 52 = 164
Answer:
136 cm²
Step-by-step explanation:
The composite figure is made up of a triangle and a rectangle.
Area of the triangle
[tex]\boxed{\begin{aligned}\textsf{Area of a triangle}&=\dfrac{1}{2} \times \sf base \times height\\\\ \implies \textsf{Area of $\triangle ABD$}&=\dfrac{1}{2} \times BD \times AB\\&=\dfrac{1}{2} \times (16-8) \times (13-7)\\&=\dfrac{1}{2} \times 8 \times 6\\&=4 \times 6\\&=24\; \sf cm^2\end{aligned}}[/tex]
Area of the rectangle
[tex]\boxed{\begin{aligned}\textsf{Area of a rectangle}&=\sf width \times length\\\\ \implies \textsf{Area of rectangle $BCFE$}&= EF \times CF\\&=7 \times 16\\&=112\; \sf cm^2\end{aligned}}[/tex]
Therefore, the area of the composite figure is:
[tex]\boxed{\begin{aligned}\textsf{Area of the composite figure}&=\sf Triangle + Rectangle\\ & = 24 + 112\\&=136\; \sf cm^2\end{aligned}}[/tex]

I=3,875.78
P=1,900
R=4% I.e 4/100 , 0.04
T=?
I=PRT

Need help I’m suck on this problem
this is a sketch of the curve with equation y=f(X). The curve has a minimum point at M(-1,-3).
The minimum point of the function y=f(x)+3 is at (-1 , 0 ) .
The biggest and lowest value of a function, either inside a specific range (the local or relative extrema) or on the entire domain, are generally referred to as extrema (plural of extremum) in mathematical analysis (the global or absolute extrema). One of the first mathematicians to suggest the general method of adequacy for determining the maxima and minima of functions was Pierre de Fermat.
The maximum and minimum of a set are the greatest and least items in the set, as described by set theory. There are no minimum or maximum values in unbounded infinite sets, such as the set of real numbers.
Say that (x,y) = where y = f(x) minimum occurs at (-1,-3). As a result, for all other x inside its domain of definition, y= f(x) >=-3
y = f(x) + 3 simply elevates the graph of y by 3 and increases the value of y for any x. Its minimum x-value remains at -1, and its value for y is f(3) + 3 = -3 + 3 = 0. as a result, new minimum =(-1 , 0 ) .

Solve this quickly please!!
Answer:
Step-by-step explanation: we will first work out a
so 23 is the hypotenuse
a is the opposite
so what we need to do is 46sin(23) and that will give you 17.97 cm
next we will work out b
b is the adjacent
23 is the hypotenuse
so in this case we must do 46cos(23) and that will give you 42.34
last, we will work out B
a is 17.97 cm and its the adjacent
23 is the hypotenuse
so we do sin-1(17.97/23)= 51.38
