Answer:
x = -7.25
Step-by-step explanation:
multiply -4 by 2x + 5 = -8x - 20
-8x -20 -3 = 35
-8x - 23 = 35
-8x = 35 + 23
-8x = 58
x = 58 / -8
x = -7.25
48+(6 + 2)
You first add the numbers in the parentheses so 6+2 =8
That leaves 48+8
The final answer would be 56
Hope this helped :)
So,
The diameter is 8.6ft. We need to convert to radius.
2 radius = 1 diameter
8.6/2 = 4.3 ft.
3.14(18.49)
58.0586ft.²
Divide by 2 (semi-circle)
29.0293ft.²
Differentiate both sides with respect to
:
When
, you have
For part (b), we now assume that
and
are functions of an independent variable, which we'll call
(for time). Now differentiating both sides with respect to
, we have
where the chain rule is used on the right side. We're told that
is decreasing at a constant rate of 0.1 units/second, which translates to
. So when
, you have
where the unit is again units/second.
Answer:
You would get $40.52 back.
Step-by-step explanation:
1.50+1.99+5.99
$9.48
50-9.48=40.52
You would get $40.52 back.
