Answer: I think it would be 3.5
Step by Step Explanation: BRAINLIEST?!?
I believe the answer is A! I hope that's correct! :)
Solution
Step 1
Write an expression for the area of sector
Where
θ = 52°
π = 3.14
r = 8cm
Step 2
Find the area of the sector after substitution of values into the formula above.
To the nearest tenth the area of the shaded sector of circle C = 29.0cm²
Answer:
<h3>
33°</h3>
Step-by-step explanation:
Sum of measures of angles in any triangle is 180°
The maesure of right angle is 90°
So: m∠EFD = 180° - 90° - 57° = 33°
Hello :
y = 3x²+9x
= 3(x² + 3x )
= 3 ( x² +2(3/2)x +(3/2)²) -(3/2)²)
= 3((x+3/2)² -9/4)
y = 3 (x+3/2)² -27/4
<span>the x-coordinate of the vertex is : - 3/2</span>
