Answer:
349
Step-by-step explanation:
We know that a₁ (the first term) is 6 and d (the common difference) is 13 - 6 = 7.
Explicit formula: aₙ = a₁ + (n - 1)d = 13 + (n - 1) * 7 = 7n - 1
Therefore, a₅₀ = 7(50) - 1 = 349
The y-intercept in this scenario is y= 5x+2
The shaded region is above the line so it would be y> so then the equation is y=4x+2 since the graph has a y intercept of 2 and a slope of four
tl;dr the answer is B
area = pi times radius squared
area = pi times 5 squared
area = pi times 25
area = 78.54
answer : 78.54 square feet
A place I go to graph is go to desmos. It works well for this. All you have to do is snip the picture of your graph
