A figure is shown, where triangle ABC is similar to triangle ADE. The location of point A is (1.2,2.1). The line connections points A,B, and D passes through the origin. What is a possible order pair for point D
Answers
Answer:
8 and 14 im 100% sure its 8 and 14
Step-by-step explanation:
The possible order pair for the point D is (0, 0.72)
What is the similarity of triangles?Triangles with the same shape but different sizes are said to be similar triangles. Triangle resemblance is shown here by the symbol "≈"
Since triangle ABC is similar to triangle ADE, the corresponding sides of these triangles are proportional.
Let's denote the length of AB as x and the length of AD as y. Then, we can write:
AB/AD = BC/DE
Substituting the values from the figure, we get:
x/y = 5/3
Multiplying both sides by y, we get:
x = (5/3)
x = (5/3)y
Substituting x = 1.2 (the x-coordinate of point A) and solving for y, we get:
1.2 = (5/3)y
y = (3/5)(1.2)
y = 0.72
Therefore, a possible order pair for point D is (0, 0.72).

The function is discontinuous at x =

To create the extended function, add f(x)=
.
Answers
Answer:
0 & -16,x=0
Step-by-step explanation:
The function is discontinuous at x = 0, x = 1/4 and x = -1/4.
To create the extended function, add f(x) = 0.
What does it mean when a function is discontinuous?A function is discontinuous when the f(x) cannot be defined.
What is an extended function?An extended function aims to make the function continuous at some values of the variable.
It is given that:
[tex]f(x)=\frac{2x^{2}+16x}{16x^{3}-x}[/tex]
StepsStep 1 of 2:The function becomes discontinuous when the denominator becomes zero.
∴ 16x³ - x = 0
⇒ x(16x² - 1) = 0
⇒ x = 0 and 16x² -1 = 0
This is further simplified:
16x² -1 = 0
x² = 1/16
x = ±1/4
This means that the function is discontinuous at x = 0, x = 1/4 and x = -1/4.
Step 2 of 2:The function can be extended as follows:
[tex]f(x)=\frac{2x^{2}+16x}{16x^{3}-x}\\f(x)= \lim_{x \to 0} \frac{2x^{2}+16x}{16x^{3}-x}\\= \lim_{x \to 0} \frac{x(2x+16)}{x(16x^{2}-1)}\\= \lim_{x \to 0} \frac{2x+16}{16x^{2}-1}\\[/tex]
We do not have to add anything to f(x) to extend it. Hence zero can be added to it.
Therefore, we have found that the function is discontinuous at x = 0, x = 1/4 and x = -1/4, and that we can create the extended function by adding 0.

The time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H, applied to the pot. When H = 8, T = 120. Work out T when H = 10
Answers
Answer:
T = 96
Step-by-step explanation:
From the question given above, we were told that the time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H. This can be written as:
T ∝ 1/H
T = K/H
Cross multiply
K = TH
Next, we shall determine the value of K. This can be obtained as follow:
H = 8
T = 120
K =?
K = TH
K = 120 × 8
K = 960
Finally, we shall determine the value of T when H = 10. This can be obtained as illustrated below:
H = 10
K = 960
T =.?
T = K/H
T = 960/10
T = 96

The population of rabbits on an island is growing exponentially. In the year 1992, the population of rabbits was 8300, and by 2000 the population had grown to 21500. Predict the population of rabbits in the year 2009, to the nearest whole number.
Answers
Answer:
36350
Step-by-step explanation:
1992 : 8300
2000 : 21500
1992/2000 = 8300/21500
Each year, population grow around 1650 rabbits
In 2009: 21500+(1650*9) = 36350
find x and y in
(i) 23x- 29y= 98 and 29x -23y =110
(ii) 99x +101y =499 and 101x +99y =501
Answers
Answer:
23 x-29y=98.......(1)
29 x-23y=110.......(2)
adding (1) and (2)we get
52 x-52y=208
52(x+y)=208
x-y=4...(3)[we get four by dividing 208 with 52]
subtract (2) from (1) we get
-6 x-6y=-12
x-y=2.....(4)
adding (3) and (4) we get
2x=6
therefore x=3
now from (4) we get
x-y=2 [we substitute xfor 3]
3-y=2
y=2-3
y=-1( that is the answer for your first question)
Step-by-step explanation:
99x+101y=499.....(1)
101x+99y=501.....(2)
add (1) and (2)
(99+101)x+(101+99)=(499+501)
200x+200y=1000
200(x+ y)=1000
x+y=5.....(3)
subtract (2)from(1) we get
2x-2y=2
2(x-y)=2
x+y=1.......(4)
x+y=5
x-y=1(add them together)
2x=6
x=3
substitute x equal to 3 in equation (3)
x+y=5
3+y=5
y=2
y equal to 2 and x equal to 3
hope is not too lateHelp........Betty wants to bake the perfect cookie. She wants to determine the ideal temperature at which to bake the cookies. She has enough batter to make 60 cookies. She decides to randomly assign 15 cookies to be baked at 300°, 15 at 325°, 15 at 350°, and 15 at 375°. The baking time for each batch is 12 minutes. Which statement about the randomization for the completely randomized design is correct? Betty should place the first 15 balls of cookie dough that she scoops from the batter on a tray, and those will be baked at 300°. The next 15 will be placed onto a second tray to be baked at 325°. She should continue in this manner until all 60 cookies have been placed on trays. Betty should scoop a ball of cookie dough from the batter, and then roll a die. Numbers 1–4 would indicate at which temperature the cookies will be baked, and 5–6 would indicate that she should roll again. She should repeat this process until all 60 cookies have been allocated. Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated. Betty should place the first cookie on a tray to be baked at 300°. The second cookie will go on a tray to be baked at 325°, the third will go on a tray to be baked at 350°, and the fourth will go on a tray to be baked at 375°. She will continue placing the cookies in this pattern until all 60 cookies are on trays to be baked.

Answer: Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.
Step-by-step explanation: I just got it correct on Edge :)
The true option about the randomized design is (c) Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.
The given parameters are:
[tex]\mathbf{n = 60}[/tex]
[tex]\mathbf{Batches = 4}[/tex]
[tex]\mathbf{Cookies= 15}[/tex] ---- the number of cookies in each batch
[tex]\mathbf{Temperature= 300,325,350,375}[/tex]
To randomly assign the cookies to the given temperatures, all cookies have to be subjected to the same conditions (except the difference in the temperature).
This means that, she can bake all the cookies at once at different temperatures, while noting down the cookies with a given number.
Hence, the true option is (c)
