Triangle ABC is taken to triangle A'B'C' by a dilation. Which of these scale factors for the dilation would result in an image that was larger than the original figure? Select all correct answers. A
Answers
Answer:B
Step-by-step explanation:
For [K] > 0, the dilated image will be larger than the original image.
What is triangle?
A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a triangle ABC which is taken to triangle A'B'C' by a dilation.
After dilation by scale factor [K], the length of the sides of triangles change by the following rule -
A'B' = K(AB)
B'C' = K(BC)
C'A' = K(CA)
If K < 0, the image will shrink. If K > 0, the image will enlarge
Therefore, for [K] > 0, the dilated image will be larger than the orginal image.

Which function is equivalent to q ( x ) = 9x 2 − 24x + 16?
Answers
q ( x ) = 9x 2 − 24x + 16 = (3x-4)^2
The closest answer to it would be

You feed your pet 1/4 cup of food each morning.
You do this for 5 days. How much total food have
you fed your pet after 5 days?
Answers
Answer:
1 1/4 cups
Step-by-step explanation:
you feed your dog 1/4 cups of food each day. You do this for five days. So we can set up an equation 5*1/4 = 1 1/4 cups.
.25*5= 1.25
1.25; 1 1/4
1 cup and 1/4ths of food
You and a few friends went to play golf and scored the following.
98, 96, 98, 134, 99
If two other friends join, and score 93 and 117, which part of the data will be effected?
Answers
Answer:
The range will change
Step-by-step explanation:
Here, we want to know the part of the data that will be affected
Firstly, we have to understand that the mean will be left unchanged
The mean is the sum of the numbers divided by the count of the numbers;
(98 + 96 + 98 + 134 + 99)/5 is same as (98 + 96 + 98 + 134 + 99 + 93 + 117) = 105
The median will be the same
before the addition of the two new numbers;
96,98,98,99, 134
The median is 98
adding the two;
93,96,98,98,99,117,134
The mode will still be the same as the highest in frequency will still be 98
however the range will change
This is the difference between the highest and the lowest numbers
Before the addition of the two numbers, the range is 134-96 = 38
adding the two numbers, the range will become;
134-93 = 41
8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answers
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13

The solution set of an inequality is shown below.

D. 6
Answers
The inequality shown in the option D, 6 < x + 3 < 9 has the given solution set.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
A number line is a straight line which is drawn horizontally where numbers are placed in an equal intervals.
Given a number line where the interval from 3 to the number 6 is marked.
But 3 and 6 is not included since it is an open circle there.
So the inequality represented in the number line is 3 < x < 6.
We have to find the inequality in the option which is equivalent to 3 < x < 6.
Consider 6 < x + 3 < 9
Subtracting throughout the inequality with 3, we get,
6 - 3 < x + 3 - 3 < 9 - 3
3 < x < 6.
Hence the inequality represented in option D has the solution represented in the number line.

oh god does anyone understand this? I need help it’s for a test and I wanna do good!!
Answers
Answer:
A
Step-by-step explanation:
Its a right angle, so you have to use trigonometry.
To find x , you use sin60° = opposite/hypotenuse
opposite = x and hypotenuse = 5 . So,
sin60°= x/ 5
5sin60° = x
put the value into your calculator you ' ll get:
[tex] x = \frac{5 \sqrt{3} }{2} [/tex]
To find y, cos60°= adjacent/hypotenuse
adjacent= y and hypotenuse = 5. So,
cos60°= y/5
5cos60°=y
[tex]y = \frac{5}{2} [/tex]
Hope I was able to help. Good luck!<3

Answer:
BC=53.68
Step-by-step explanation:
Use tangent since you are finding the opposite side and given the adjacent side.
tan(54)=BC/39
BC=53.68
Answer:
C
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan54° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{39}[/tex] ( multiply both sides by 39 )
39 × tan54° = BC, then
BC ≈ 53.68 ( to 2 dec. places ) → C
