Answer:
Step-by-step explanation:
The radius, r of the expanding circle of oil is modeled by the function:
, where s is time in seconds.
When s=5
Radius 
Area of a circle 
Therefore, the area of the oil spill when s=5 seconds
The area of the spill when s=5 seconds is 45pi square inches.
Answer:
x = - 6, x = 6
Step-by-step explanation:
Given
x² + 7 = 43 ( subtract 7 from both sides )
x² = 36 ( take the square root of both sides )
x = ± 
= ± 6
Thus
x = - 6, x = 6
A regular polygon is drawn in a circle so that each vertex is on the circle
Each of the central angles has a measure of 40
360 / 40 = 9
so the polygon has 9 sides
Answer is the second option
9
Well, assuming that Liam, Raj, and Gemma all have squares identical to each other, then you would first add them all up. 14+12+15=41. Then, you would divide the total number of squares by the number of squares in a quilt. 41/10=4.1, or 4 1/10.
Hope this helps!
Answer:
Sides in descending order: YZ > ZX > XY
Step-by-step explanation:
Sum of all angles of triangle = 180
104 +52 + ∠Z = 180
156 + ∠Z = 180
∠Z = 180 - 156
Z = 24
The sides opposite to the biggest is the longest side.
Angles in descending order: ∠X > ∠Y > ∠Z
