Answer:
5 < x < 21
Step-by-step explanation:
The shortest would be if the 8 leg folded back on the 13 leg
13 - 8 > 5
The logest would be if the 8 leg extended the 13 leg
13 + 8 < 21
Therefor
5 < x < 21

Solve algebraicallu for the solutions of equations below.
Step-by-step explanation:
Okay, the first step is to rewrite this equation in "vertex form." You can search that up but it's basically just (h/k).
y = ( x − 1) 2 + 3
Now, we are going to use the vertex form, "y = a (x - h)2 + k, to get the values of a, h, and k.
By using the form we get 1 for the value a, 1 for the value h, and 3 for the value k.
1 = a
1 = h
3 = k
Becuse the value of a is positive, the parabola opens up! (A parabola is the U shaped line in a graph, so that opens up.)
Now, we find the vertex (h,k)
which is (1,3)
Now we find the p from the vertex to the focus. (vertext the top, focus one of the points.)
Follow this formula to find the distance from the vertex to a focus by using this formula
1/4a.
Now we just gonna substitue 1 for a, since we know that 1 equals a above ^
1/4 * 1
Solving that, we got a nice little 1/4.
Next we find the focus
"Find the focus.
The focus of a parabola can be found by adding p to the y-coordinate k if the parabola opens up or down.
(h,k+p)
Substitute the known values of h, p, and k into the formula and simplify.
(1,134)
Find the axis of symmetry by finding the line that passes through the vertex and the focus.
x=1
Find the directrix.
y=114
Use the properties of the parabola to analyze and graph the parabola.
Direction: Opens Up
Vertex: (1,3)
Focus: (1,134)
Axis of Symmetry: x=1
Directrix: y=114
Select a few x values, and plug them into the equation to find the corresponding y values. The x values should be selected around the vertex.
xy−1704132437
Graph the parabola using its properties and the selected points.
Direction: Opens Up
Vertex: (1,3)
Focus: (1,134)
Axis of Symmetry: x=1
Directrix: y=114

Answer:
Measure of segment JL is 20 cm.
Step-by-step explanation:
By applying geometric mean theorem in the given right triangle,
[tex]\frac{JM}{KM}=\frac{KM}{ML}[/tex]
[tex](KM)^2=(LM)(ML)[/tex]
[tex]8^2=(JM)(4)[/tex]
[tex]JM=\frac{64}{4}[/tex]
[tex]JM=16[/tex]
Since, [tex]JL=JM+ML[/tex] [By segment addition postulate]
[tex]JL=16+4[/tex]
[tex]JL=20[/tex] cm
Therefore, measure of segment JL is 20 cm.

Which is the factored form of x(w – 1) + (W – 1)?
22 pts
Answer:
Solution given:
x(w – 1) + (W – 1)
distribute it:
xw-x+w-1
xw+w-x-1
take common from each term
w(x+1)-1(x+1)
take common again
(x+1)(w-1)
the factored form of x(w – 1) + (W – 1) is (x+1)(w-1).

Joanne puts 40 bacteria in a petri dish. The population of bacteria is doubling every hour. Which function best represents the situation?
please help ill give brainliest answer!
Answer:
OC=48
RK=100
Step-by-step explanation:
We can use proportions to find both OC and RK.
[tex]\frac{OK}{KY} =\frac{OC}{RY}[/tex]
[tex]\frac{12}{24} =\frac{OC}{96}[/tex]
[tex]24OC=1152[/tex]
[tex]OC=48[/tex]
[tex]\frac{KC}{RK} =\frac{OK}{KY}[/tex]
[tex]\frac{50}{RK} =\frac{12}{24}[/tex]
[tex]12RK=1200[/tex]
[tex]RK=100[/tex]
Answer:
RK = 100
OC = 48
Step-by-step explanation:
Scale factor = 12/24 = 1/2
1/2 RK = 50
RK = 2* 50
RK = 100
1/2 RY = OC
1/2 * 96 = OC
48 = OC
OC = 48

Margaret works at a clothing store. Today she has sold only shirt and pants.The ratio of the number of shirts sold to the number of the items sold to 2/5. Which model shows this to ratio
Answer:
Shirt : Pant = 2 : 3 , & Pant : Shirt = 3 : 2 , Linear model can be used.
Step-by-step explanation:
Ratio of ' Number of shirts sold : Number of items sold' = 2 : 5
Let the common ratio be = x
Then, number of shirts sold = 2x. And, number of total items sold = 5x.
So, number of pants sold = Number of items sold - number of shirts sold = 5x - 2x = 3x
So, shirt to pant ratio = 2x / 3x = 2 : 3 .And, pant to shirt ratio = 3 : 2
This model can be shown in linear equation, as all are linear powered.

Answer:
468 in ^2; a
Step-by-step explanation:
Add each side of the prism;
Base: 15*10 = 150
Rectangular sides: 10*12+9*10 = 210
Triangular sides (x2): ((9*12)/2)*2 = 108
108+210+150 = 468 in ^2

A kite is flying on a string that is 73 feet long. The angle
the kite makes with the ground is 51 degrees. How high
is the kite flying?
Answer:
56.73 ft
Step-by-step explanation:
Given:
51° (angle)
73ft (hypotenuse)
With the given information use sin to determine the height of the kite.
sin51° = x/73
solve for x (height)
x= 73*sin51°
x= 56.73ft
