Answer:
I think the answer is 9 3/4, 9.5, 9 3/8, 9.125
Sydney's age is 27 years of age. A way to do this is by subtracting 9 from 45 to get 36 and dividing it by 2 which gets you 18 and then adding 9 to that number since 18 is how old Devaughn is
Answer:
- 2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.
Step-by-step explanation:
- <em>Easy way to take one of the vertices and apply the transformations</em>
1. Rotate the triangle 90º counterclockwise about the origin and then translate it 10 units left and 9 units down.
2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.
- True
- (-3, 3) → (3, 3) → (3 - 10, 3 - 9) = (-7, -6)
3. Rotate the triangle 90º counterclockwise about the origin then translate it 1 unit up.
4. Rotate the triangle 90º clockwise about the origin then translate it 1 unit up.
Answer:
[2.1, 3]
Step-by-step explanation:
Given the height of the ball modelled by the equation;
h(t) =-4.9t^2+25t+6
Required
Domain for 36.9m
To get that we are to find the value of the input variable which is the time t when h(t) = 36.9
Substitute
36.9 = -4.9t^2+25t+6
multiply through by -10
-369 = 49t²-250t-60
49t²-250t-60 + 369 = 0
49t²-250t+309 = 0
Find the domain of t
49t²-147t-103t+309 = 0
49t(t-3)-103(t-3) = 0
(49t-103)(t-3) = 0
49t - 103 = 0 and t-3 = 0
49t = 103 and t = 3
t = 103/49 and t = 3
t = 2.1 and t = 3
Hence the reasonable domain for 36.9m is [2.1, 3]
