Answer:
11
Step-by-step explanation:
Each number in the sequence decreases by 4, so the next reasonable number would be 11 (15-4=11)
Answer:
B is the correct answer
Step-by-step explanation:
becasue if you solve this you get (0,0) (1,20) and (2,40) so b is the correct answer
Answer:
x₁ = (1 + √43)/6
x₂ = (1 - √43)/6
Step-by-step explanation:
6x² - 2x = 7
6x² - 2x - 7 = 0
Formula
ax² + bx + c = 0
a = 6 ; b = - 2 ; c = - 7
x₁/₂ = [-b ± √(b²- 4ac)]/2a
x₁/₂ = (2 ± √4 + 4×6×-7)/12
x₁/₂ = (2 ± √172)/12
x₁/₂ = (2 ± 2√43)/12
x₁/₂ = 2(1 ± √43)/12
x₁/₂ = (1 ± √43)/6
x₁ = (1 + √43)/6
x₂ = (1 - √43)/6
Answer:
78
Step-by-step explanation:
You know that each minute represents 6 degrees of a difference because there are 360 degrees total and 60 minutes, so 360/60 = 6 degrees.
13 minutes passed, so 13 * 6 = 78 degrees
