Answer:
Option D is correct
Step-by-step explanation:
Option D is correct
Being an arithmetic sequence there will be common difference between the consecutive terms
Option A is incorrect because it is not necessary that explicit formula is an arithmetic sequence we can create explicit formula for any sequence
Option B is incorrect because recursive formula can be created for any sequence for geometric series also.
Option C is incorrect because the sequence that has constant ratio is the geometric sequence not an arithmetic sequence.
Answer:
The slope of the line is zero and the y is 17.5
Step-by-step explanation:
2y=31+4
31+4= 35
2y=35
and then you divide and you get 17.5
The intercept is (0,) and/or (0,17.5)
Answer:
The values of x and y are x = -3 and y = -2
Step-by-step explanation:
In the complex numbers if a + bi = c + di, then the real parts are equal and the imaginary parts are equal
Let us use this rule to solve the question
∵ -21 + 5yi = 7x - 10i
∴ The real parts are -21 and 7x
∴ The imaginary parts are 5y and -10
∵ The real parts are equal
∴ 7x = -21
→ Divide both sides by 7
∴ =
∴ x = -3
∵ The imaginary parts are equal
∴ 5y = -10
→ Divide both sides by 5
∴ =
∴ y = -2
∴ The values of x and y are x = -3 and y = -2
64 km x 0.62137 = 39.76768 miles per hour
64.4 x 0.62137 = 40.016228 miles per hour
40.016228 - 39.76768 = 0.248548 miles per hour faster
1 mile =5280 feet
5280 * 0.248548 = 1312.33 feet per hour
3600 seconds per hour
1312.33 / 3600 = 0.37 feet per second faster
