The answer is D
This is because the -6 represents the y-intercept and D is the only one where it passes through -6
Answer to the slope and y-intercepts at the top:
#2: slope = -3 & y-intercept = (0,5)
#3: slope = 1 & y-intercept = (0, 4)
#4: slope = 5/6 & y-intercept = (0, -3)
#5: slope = -3 & y-intercept = (0, -7)
#6: slope = 1/5 & y-intercept = (0, 2)
Answers for the equations at bottom:
#5: y = 4/9x + 7
#6: y = -x - 6
#7: y = 2x + 5
#8: y = -4x + 7
Hope this helps! :)
Graph theory is the idea and study of graphs within the field of math.
Answer:
587.18 in²
Step-by-step explanation:
In the above question, we are given the following values
Diameter = 11 inches
Radius = Diameter/2 = 11 inches/2 = 5.5 inches
Slant height = 28.5 inches.
We were asked to find how many square inches of paper will she need to cover the ENTIRE cone.
To solve for this, we would use formula for Total Surface Area of a Cone
Total Surface Area of a Cone = πrl + πr²
= πr(r + l)
Using 3.14 for π
Total Surface Area of a Cone
= 3.14 × 5.5( 5.5 + 28.5)
= 3.14 × 5.5 × (34)
= 587.18 in²
Therefore, Anita will need 587.18 square inches of paper to cover the entire cone.
