Answer:
The area of the regular octagon is
Step-by-step explanation:
we know that
The area of the regular polygon is equal to
where
P is the perimeter of the regular polygon
a is the apothem
<em>Find the perimeter P</em>
Find the area
Answer:
Step-by-step explanation:
Paraboloid z = 6 + 2x^2 + 2y^2 ----- ( 1 )
plane z = 12
equation 1 becomes
12 = 6 + 2( x^2 + y^2 )
hence : ( x^2 + y^2 ) = 3
This shows that the solid lies under the parabolic and above the disk 0 : x^2 + y^2 ≤ 3
attached below is the remaining part of the solution
The answer for this one is C
Answer:
$14.70
Step-by-step explanation:
If she get paid the time and a half you would first divide $9.80 by 2 which is $4.90. Now that you have the half price you add the original time to it. $9.80+$4.90= 14.70 so that’s the answer
Answer:
x^2+27x+180
Step-by-step explanation:
okay so -12 and 15 are the only solutions
work backward
add 12 and add 15 from x
(x+12)(x+15)
then solve this
x*x=x^2
x*+15=15x
12*x=12x
12*15=180
now put it all together
x^2+15x+12x+180
then simplify
x2+27x+180
(x+12)(x+15)
Then solve again to try it.
x+12=0
x+15=0
x=-12
x=-15
Hope this helps.
