It would be B. "Regular" factoring without the quadratic formula can't be done. Completing the square will work easily since the coefficient on the squared term is a 1. I personally wouldn't graph this to find the solutions, although you could with and x/y chart to give you enough coordinates to plot the graph correctly.
Answer:
942.5 in²
Step-by-step explanation:
The formula for the area (A) of a sector of a circle is
A = ½r²θ
where θ is the angle in radians.
1. Convert the angle to radians
θ = 125°
2. Area swept out by wiper arm
A = ½r²θ = ½ × (30 in)² × θ = ½ × 900 in²× θ = 450 θ in²
3. Area missed by wiper
A = ½r²θ = ½ × (6 in)² × θ = ½ × 36 in²× θ = 18 θ in ²
4. Area covered by wiper
A = 450 θ in² - 18 θ in² = 432 θ in²
5. Insert the value of θ
A = 432 × 25/36 π in² = 300π in² ≈ 942.5 in²
The area swept out by the wiper blade is 942.5 in².
The answer is C
c+5/9 (f-32)
f=40
c+5/9(40-32)
c+40/9
=4 4/9
Answer:
<em><u>Only 4 different 3 topping pizzas are possible.</u></em>
Step-by-step explanation:
<em><u>H</u></em><em><u>o</u></em><em><u>p</u></em><em><u>e</u></em><em><u> </u></em><em><u>i</u></em><em><u>t</u></em><em><u> </u></em><em><u>w</u></em><em><u>o</u></em><em><u>r</u></em><em><u>k</u></em><em><u>s</u></em><em><u> </u></em><em><u>o</u></em><em><u>u</u></em><em><u>t</u></em><em><u> </u></em><em><u>:</u></em><em><u>)</u></em><em><u>)</u></em>
the answer is 130 degrees, the 2 interior bottom angles are = to one another so 65 and 65, adding them up makes it 130, then 180 - 130 = 50, meaning the top interior angle is 50 degrees, then 180 - 50 is 130.
