Line segment AB was dilated to create line segment A'B' using the dilation rule DQ,0.15.
What is x, the distance between points A and A'?
2.4 units
4.8 units
13.6 units
14.4 units
Answers
Answer:
13.6
Step-by-step explanation:
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor as follows:
dilation factor = A'Q/AQ
AQ = A'Q/dilation factor
Replacing with data:
AQ = 2.4/0.15 = 16
Then, the distance between points A and A' is
x = 16 - 2.4 = 13.6
The distance between points A and A' is 13.6 units
Dilation of coordinatesDilation is a way of changing the position of an image on an xy-plane.
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor. Hence'
scale factor = A'Q'/AQ
Given the following
A'Q' = 2.4
Scale factor = 0.15
Substitute
AQ = 2.4/0.15
AQ = 16
x = 16 - 2.4
x = 13.6
Hence the distance between points A and A' is 13.6 units

Does every line have a slope and a y intercept?
Answers
Answer:
see below
Step-by-step explanation:
Not every line has a y intercept because vertical lines ( lines that go up and down) do not intersect the y axis
Does every line have slope? It depends on how you define slope
Vertical lines have a slope that is undefined. So they have a slope that is undefined. When you are asked what the slope of a vertical line is , you answer undefined
Answer:
no
Step-by-step explanation:
because the line can be 0

A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream
Answers
Answer:
t=4h
Steps below
Step-by-step explanation:
We know:
speed of boat with respect to earth: 13 km
speed of stream with respect to earth: 4 km
13 km/h + 4 km/h = 17 km/h The time to travel 68 km with this speed is thus t = 68 km 17 km h = 4 h

5x + 3 + Y = 180
5x + 3 + 52 = 180
5x + 55 = 180
5x = 180 - 55
5x = 125 °
x = 125 ÷ 5

If Candace made a scatter plot of the math scores of eighth-grade students (vertical scale) and their heights in inches (horizontal scale), what type of line of best fit should she expect the scatter plot show?
A. a line with positive slope
B. a line with negative slope
C. a horizontal line
D. There would be no line of best fit.
Answers
Answer:
The correct option is (D).
Step-by-step explanation:
A scatter plot is a mathematical graph used to display the linear relationship between two variables.
Points are plotted on the graph and a line of best is drawn to represent the linear relationship between the two variables.
If the line is upward moving this implies that there is positive relation between the variables.
If the line is downward moving this implies that there is negative relation between the variables.
If there is no line of best fit that can be formed using the data provided then this implies that there is no linear relationship between the variables.
The variables math-score and height of the students has no relation between them. This is because the height of a student does not factor the score he/she received in their math exam.
So, the scatter plot for this data will not have a line of best fit.
Thus, the correct option is (D).

Answers
Answer:
8/45
Step-by-step explanation:
1. Since the dice has six sides and only two numbers are less than three (2 and 1) that means there is a 4/6 (2/3) chance of them rolling any other number besides 2 and 1. Since in bag two it has the yellow dice.
2. In bag two there are a total of 15 beads (4 yellow and 11 blue) since we want to get the yellow bead that means there is a 4/15 chance of getting a yellow bead.
3. Finally to find the chance of rolling a number greater than 2 and picking a yellow bead you must multiply the numerators and denominators. 2(4) and 3(15) which in turn equals 8/45.

Step-by-step explanation:
To find the first 4 terms, substitute n = 1, 2, 3, 4 into the sequence rule.
For the 10 th term substitute n = 10 into the sequence rule
(a)
n = 1 → 1² + 3 = 1 + 3 = 4
n = 2 → 2² + 3 = 4 + 3 = 7
n = 3 → 3² + 3 = 9 + 3 = 12
n= 4 → 4² + 3 = 16 + 3 = 19
n = 10 → 10² + 3 = 100 + 3 = 103
Thus the first 4 terms are 4, 7, 12, 19 and term 10 is 103
------------------------------------------------
(b)
n = 1 → 2 × 1² = 2 × 1 = 2
n = 2 → 2 × 2² = 2 × 4 = 8
n = 3 → 2 × 3² = 2 × 9 = 18
n = 4 → 2 × 4² = 2 × 16 = 32
n = 10 → 2 × 10² = 2 × 100 = 200
Thus the first 4 terms are 2, 8, 18, 32 and term 10 is 200

In the NBA, any shot made from 22 feet or more from the basket is worth 3 points. How many yards from the basket is that?
Answers
Answer:
22/3 yards, roughly 7.33 yards.
Step-by-step explanation:
We know that there is 3 feet in 1 yard.
Given 22 feet, we divide by 3 to find the amount of yards, thus changing the unit.
The exact amount of yards is just 22/3, which you can estimate to 7.33 yds.
