Answer:
72 km/hour
Step-by-step explanation:
20 m/s × (1 km/(1000 m)) × (3600 s/h) = 72 km/h
The rate is 72 kilometers per hour.
Answer:
Option d is correct.
The number of students that chose Target as their favorite store over Ross = 4 students.
Step-by-step explanation:
The graph of the question is obtained from another brainly question on here. But uploading it will lead to deletion of this answer as it would be violating the community guidelines here.
So, I'm going to describe the graph.
The graph provided with the question is a pie chart, with each region clearly shown and the corresponding percentage for each of the students' favourite stores that come up in the survey given as
TJMax - 20%
Wal-Mart - 25%
Ross - 20%
Target - 25%
Others - 10%.
How many more students surveyed chose Target as their favorite store over Ross?
Total number of students sampled = 80
Number of students that picked Target
= 25% × 80 = 20 students
Number of students that picked Ross
= 20% × 80 = 16 students.
Number of students that chose Target as their favorite store over Ross = 20 - 16 = 4 students.
Hope this Helps!!!
Answer:
Horizontal shift of 4 units to the left.
Vertical translation of 8 units downward.
Step-by-step explanation:
Given the quadratic function, y = (x + 4)² - 8, which represents the horizontal and vertical translations of the parent graph, y = x²:
The vertex form of the quadratic function is y = a(x - h)² + k
Where:
The vertex is (h , k), which is either the <u>minimum</u> (upward facing graph) or <u>maximum</u> (downward-facing graph).
The axis of symmetry occurs at <em>x = h</em>.
<em>a</em> = determines whether the graph opens up or down, and makes the graph wider or narrower.
<em>h</em> = determines how far left or right the parent function is translated.
<em>k</em> = determines how far up or down the parent function is translated.
Going back to your quadratic function,
y = (x + 4)² - 8
- The vertex occrs at (-4, -8)
- a is assumed to have a value of 1.
- Given the value of <em>h</em> = -4, then it means that the graph shifted horizontally by <u>4 units to the left</u>.
- Since k = -8, then it implies that the graph translated vertically at <u>8 units downward</u>.

The domain and the range is [-6 to +inf)
Slope: (y2-y1)/(x2-x1)
(-3+5)/(-1-7) = 2/-8 = -1/4
The answer is d) -1/4
