Answer:
1. Proved down
2. proved down
3. f(10) = -20 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5
Step-by-step explanation:
Let us explain how to solve the question
∵ f(0) = -20, f(n) = f(n - 1) - 5 for n > 1
→ That means we have an arithmetic sequence with constant
difference -5 and first term -20
1. → f(1) means we need to find the second term, which equal the
term - 5
∵ f(1) means n = 1
∴ f(1) = f(1 - 1) - 5
∴ f(1) = f(0) - 5
∵ f(0) = -20
∴ f(1) = -20 - 5 → Proved
2. → f(3) means we need to find the third term, which equal the
second term - 5
∵ f(3) means n = 3
∴ f(3) = f(3 - 1) - 5
∴ f(3) = f(2) - 5
→ f(2) = f(1) - 5
∵ f(1) = -20 - 5
∴ f(2) = [-20 - 5] - 5 = -20 - 5 - 5
∴ f(3) = [-20 - 5 - 5] - 5
∴ f(3) = -20 - 5 - 5 - 5 → Proved
3. → From 1 and 2 we notice that the number of -5 is equal to n,
at n = 1 there is one (-5), when n= 3 there are three (-5)
∵ n = 10
∴ There are ten (-5)
∴ f(10) = -20 - 5(10)
∴ f(10) = -20 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 - 5 → Proved
I don’t think there is anything wrong with the coming there is just a 50% chance that It would land on tails and there’s a 50% chance that it will land on heads ♀️☺️
Answer:
40 square feet
Step-by-step explanation:
The area of a parallelogram is given by the formula ...
A = bh . . . . . base b, height h
Your figure shows a base length of 10 feet and a height of 4 feet.
The area is ...
A = (10 ft)(4 ft) = 40 ft²
Answer:
Option B is correct
circumference of a circle is 785 m
Step-by-step explanation:
Circumference of the circle(C) is given by:
where
r is the radius of the circle
As per the statement:
radius of the circle is 125 m
then substitute in [1] we have
Simplify:
C = 785 m
Therefore, the circumference of a circle is 785 m
Since the 4 is underlined in 6.5<u>4</u> it means it is in the hundredths place so the value would be 0.04.
