Answer:
6
Step-by-step explanation:
radius is half the diameter
Answer:
Step-by-step explanation:
It's an equation of a linear function in the slope-intercept form:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The domain of any linear function is the set of all real numbers.
The range of any linear function where m ≠ 0 is the set of all real number.
If m = 0, then the equation of a line is y = b. Then the range is {b}.
We have m = 1/4 ≠ 0. Therefore the range is the set of any real numbers.
Just so you know, it has to be written as a lowercase i to represent an imaginary number.
a) 2i
The square root of 4 is 2, the negative under the square root is what makes it imaginary
b) 2i times the square root of 3
c) 5 + (5i times the square root of 2)
d) 3 - (i times the square root of 2)
Answer:
<u>The series:</u>
This is an AP with the first term a₁ = 10 and common difference d = 6
a) <u>Recursive formula:</u>
b) <u>Explicit formula:</u>
- aₙ = a₁ + 6(n - 1) ⇒ aₙ = 10 + 6n - 6 ⇒ aₙ = 6n + 4
c) <u>n = 5 ⇒ a₅ = ?</u>
d) <u>S₁₇ = ?</u>
- Sₙ = n(a₁ + aₙ)/2 = n(2a₁ + (n - 1)d)/2
- S₁₇ = 17(2*10 + 16*6)/2 = 986
