Answer: "two "x" plus eight" Is how you write it in word form- I hope this helps!^^
Step-by-step explanation:
The equation models the height of the ball correctly will be h = -16t² + 40t.
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A soccer ball is kicked into the air from the ground.
g = 9.81m/s²
g = 9.81/0.3048
g =32.18.. ft/s² rounded to 32
h = -g/2t² + vt + h0
if t = 0,h = 0
h = -16t² + vt
50 ft in 2.5s
25 ft in 1.25s
25 = -16 x 1.25² + v x 1.25
v = 50/1.25
v =40
The equation models the height of the ball correctly will be h = -16t² + 40t.

D) translation
24 . The waiter places a bowl of soup in front of Abbey. In a counterclockwise direction, she passes the soup to Kai who then passes it to Haifa. Which two rotations about the center of the table describe passing the soup?
A) first 72° and then 108°
B ) first 40° and then 60°
C) first 80° and then 120°
D) first 60° and then 90°
25. The waiter places a bowl of soup in front of Lacy. In a counterclockwise direction, she passes the soup 90°. The person receiving the soup passes it 30°. After the two passes, the soup is in front of which person?
A) Garret
B) Darcy
C) Igor
D) Haifa
28. What are the coordinates of the vertices of the triangle under the translation (x, y) ---> (x - 1, y - 3)
A)(0, -8), (-1, -1), (-5, -4)
B) (-8, 0), (-1, -1), (-4, -5)
C) (5, -4), (0, 0), (5, 4)
D) (-4, 5), (0, 0), (4, 5)
29.What is the reflection image of P(0, 0) after two reflections, first across x = -3 and then across y = 4?
A) (-8, -6)
b) (4, -3)
C) (4, -6)
D) (-6, 8)
Answer:
22) (B)
24) (D)
25) (D)
28) (B)
29) (D)
Step-by-step explanation:
22) Firstly, the figure is reflected across line m and then the figure is reflected across line n.
The resultant figure is a rotated figure of original figure
(B) Rotation
24) Since there are 12 people sitting in a circle
Total circular angle = 360°
Angle between two people = 360/12 = 30°
Therefore, from Abbey to Kai there are 2 people between them. Hence, angle covered = 60°
From Kai to Haifa there are 3 people.
Angle covered = 90°
(D) is correct
25) Lacy passes the soup in 90° counterclockwise and then 30°.
Now soup is in front of Haifa.
(D) is correct
28)
Coordinates are ((0,2) -----> (x-1,y-3) = (-1,-1)
(-7,3) -------------> (x-1,y-3) = (-8,0)
(03,-2) --------> (-4,-5)
(B) is correct
Reflection of P(0,0) across x= -3, gives the point( -6,0)
And reflection across y=4, gives the point (0,8)
Together the reflected point is P(-6,8).
(D) is correct
Number of Books Read in a Year:
Number of Books Read in a Year:
Person Books
Lauren 40
40
40
Henry 70
70
70
Jamar 10
10
10
For every books Jamar read, Lauren read books.
Answer:
Step-by-step explanation:
To express the quantities given in ratio language, we need to determine the ratio between the number of books read by each person.
Lauren: For every 10 books Jamar read, Lauren read 40 books. This can be expressed as a ratio of 40:10, which simplifies to 4:1.
Henry: For every 10 books Jamar read, Henry read 70 books. This can be expressed as a ratio of 70:10, which simplifies to 7:1.
Jamar: Since Jamar is the reference point for the ratios, the ratio for Jamar will always be 1:1.
So, the ratios for the number of books read in a year are:
Lauren: 4:1
Henry: 7:1
Jamar: 1:1
These ratios represent the relative quantities of books read by each person in a year, simplifying the comparison between their reading habits.
