Answer:the distance between the x coordinates of R and T is 3.
The distance between the y coordinates of R and T is 6
R’ is 1 unit left, 2 units up from T, so the coordinates of R’ are (2,0)

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The sequence of positive odd numbers is
1, 3, 5, 7, ......
This is an arithmetic sequence with common difference d
d = 3 - 1 = 5 - 3 = 7 - 5 = 2
The sum to n terms of an arithmetic sequence is
= [2a + (n - 1)d ]
where a is the first term
here a = 1, d = 2, n = 12, hence
= [1 + (11 × 2) ]
= 6 [ 2 + (11 × 2) ]
= 6 × 24 = 144 → A
Answer:
f(16) = 2
f'(16) = 4
Step-by-step explanation:
Given:
- The function f(x) is given as:
f(x) = y = 4t - 62
Find:
- what are f (16) and f ′(16)?
Solution:
- The value f(16) is given by plugging in x = 16 into the expression given as follows:
f(16) = 4*16 - 62
f(16) = 2
- The value of f'(16) is the gradient of the function @ x = 16.
The gradient is given by the derivative of the function:
df(x) / dx = 4
Hence, f'(x) is in-dependent of the value of x and gradient is 4 for all values of x.
