Answer:
Option 1: y = (x - 2)² + 2
Step-by-step explanation:
Given the vertex, (2, 2), of an upward-facing parabola, and using the y-intercept of the graph, (0, 6):
Definitions:The vertex form of the quadratic equations is:
y = a(x - h)² + k
where:
(h, k) is the vertex.
The value of h represents the horizontal translation of the graph. h > 0 represents the horizontal shift of the graph h units to the right. h < 0 shifts the graph |h | units to the left. The value of k represents the vertical translation of the graph. k > 0 shifts the graph k units upward. k < 0 shifts the graph |k | units down.The sign of a determines the direction of the graph's opening. The value of a also determines the vertical stretch or shrink of the graph.
If a is positive (or a > 1), then the graph opens upward. The value of a > 1 also represents the vertical stretch of the graph. If a is negative (or a < 0), then the graph opens down.The value of 0 < a < 1 represents the vertical shrink or compression of the graph. Solution:Substitute the values of the vertex (2, 2) and the y-intercept, (0, 6) into the vertex form to solve for the value of the coefficient, a:
y = a(x - h)² + k
6 = a(0 - 2)² + 2
6 = a(-2)² + 2
6 = 4a + 2
Subtract 2 from both sides
6 - 2 = 4a + 2 - 2
4 = 4a
Divide both sides by 4 to solve for a :
[tex]\displaytext\mathsf{\frac{4}{4} \:=\frac{4a}{4}}[/tex]
a = 1
Quadratic Equation in Vertex Form:Therefore, given the vertex, (2, 2) and a = 1, the quadratic equation in vertex form is: y = (x - 2)² + 2, thereby matching Option 1.

Question is below!!! 9 and 10!!!! Pls help
Answers
Answer:
9. 1.75 m/s²; 8 s
10. (12 6/7) °/s; (10 5/7) kt/s
Step-by-step explanation:
Acceleration is the change in velocity divided by the change in time.
__
9.(22 m/s -15 m/s)/(4 s) = 7/4 m/s² = 1.75 m/s²
The eagle's average acceleration is 1.75 m/s².
__
The relation can also be used to find the time for a given change:
a = Δv/Δt ⇒ Δt = Δv/a
Δt = (22 m/s -8 m/s)/(1.75 m/s²) = 8 s
It would take the eagle 8 seconds to go from 8 m/s to 22 m/s.
__
10.From north to south is a direction change of 180°. Then the rate of change is ...
a = 180°/(14 s) = 12 6/7 °/s
__
From 75 knots north to 75 knots south (-75 knots, using north as a reference) the magnitude of the average acceleration is ...
|-75 kt -75 kt|/(14 s) = 150/14 kt/s = 10 5/7 kt/s

The perimeter of an equilateral triangle is 24 cm. Find the length of each sides
Answers
Answer:
8cm
Step-by-step explanation:
An equilateral triangle means that all the sides are equal (the same length). A triangle has 3 sides so all we have to do is:
24/3 = 8
Each side is 8cm long
Answer:
Length of each sides = 8 cm
Step-by-step explanation:
Given the perimeter of an equilateral triangle, 24 cm:
Equilateral triangles have three congruent sides.
Hence, to find the length of an equilateral triangle, simply divide the perimeter by 3 (since an equilateral triangle has three equal sides).
Perimeter of an equilateral triangle = 24 cm
Side = 24 cm ÷ 3 = 8 cm
Therefore, the length of each side is 8 cm.

The time, t, it takes a runner to cover a specified distance is inversely proportional to the runner's speed. If Jann Avery runs at an average of 6 miles per hour, she
will finish a race in 2. 1 hours. How long will it take Jackie Donofrio, who runs at 4 miles per hour to finish the same race?
Answers
To solve this problem you will need this tool, it is the formula of speed :
speed = distance/time
(I suggest you to remember this one for life, it is a really useful one)
Let's check how long that Jackie nice dude will take to finish the race...
Jann avery runs at an average of 6 mph (miles per hour), so we already got the speed for our formula. And she will finish the race in 2.1 hours so we got the time. What do we miss ? The distance.
Let's write what we already know to solve this puzzle :
6 = d / 2.1
Where d is that unknown distance.. So we are in front of an equation here let's solve it :
d / 2.1 = 6
d = 6 * 2.1
d = 12.6 miles
Now that we know that distance, for the race, we can see if that poor Jackie Donofrio has all his chances to catch Jann Avery...
We already know his speed... and since we have the distance, we write :
4 = 12.6 / t
Where t is the unknown time, for Jackie, to finish the same race. Let's solve the equation :
4t = 12.6 (we multiplied t on each side of the equation)
t = 12.6 / 4
t = 3.15
Jackie Donofrio, who runs at 4 miles per hour, will finish the race in 3.15 hours
Good Luck

Answers
Answer:
5:20
Step-by-step explanation:
In order to tell the time on an analog clock, we start by looking at the hour (shorter) hand. On this clock, it is pointing between the 5 and the 6, so we know it's a little after 5 o'clock.
Next, we look at the minute hand. Each number on the clock represents five minutes past the hour and the minute hand is pointing at the 4, so we know it is 4 x 5 or 20 minutes past the hour.
Therefore, we know that the time is 20 minutes after 5, or 5:20.
The time shown on the clock, obtained by reading the clock is; 5 : 20
How does one read a clock?Reading an analog clock involves looking at the positions of the clock's hands to determine the time.
The long hand, which is the minute hand of the clock is pointing at the number 4, which indicates that the time is 20 minutes past the hour, because each number on the clock face represents 5 minutes; (4 × 5 = 20). The direction the short hand, which is the hour hand is past the number 5, it indicates that the time is past 5 o'clock.
The position of the hour hand between 5 and 6 indicates that the time shown on the clock is 20 minutes past 5; 5 : 20
