Answer:
-4 1/4 When you subtract -3 3/8 from 7/8 you will get this answer.
Hope this helps
since the lengths of all those four sides are in a 3:2:6:7 ratio, and the whole perimeter is 126, what we do is, simply divide the whole by (3+2+6+7) and distribute accordingly.
Step-by-step explanation:
-10-2x = 3x+15
5x = -25
x= -5
Please use " ^ " to denote exponentiation:
<span>f(x) = –(x + 8)^2 – 1
Find the first derivative: f '(x) = -2(x+8)(1)
Set this = to 0: -2(x+8) = 0
solve for x: x = -8
Divide the number line into subintervals based upon x=-8:
(-inf, -8) and (-8, inf)
Choose a test value for x from each interval, e. g., -10 from the first interval and 20 from the second.
Subst. this test value into the derivative, shown above.
If the result is + the function is incr on that interval; if - the fn. is decr.

Answer:
39.13 units²
Step-by-step explanation:
Height of the triangle:
10cos(30) = 5sqrt(3)
Radius = ⅓(5sqrt(3)) = 5sqrt(3)/3
Triangle - circle
[½(10)(10)sin60] - [(3.14)(5sqrt(3)/3)²]
43.30127019 - 4.166667
39.13460352 unitsw
