Answer:
-510
Step-by-step explanation:
Below the sea level should be represented by negative sign.
So, -510
180-96= 84
That means 8x+12=84
84-12=72
That means 8x=72
72÷8=9
therefore X=9
Answer:
120 divided by (1 and 3/4) =
120 divided by 7/4 =
120/1 * 4/7 =
480 / 7 =
68 and 4/7 mph

The value of f(5) is 49.1
Step-by-step explanation:
To find f(x) from f'(x) use the integration
f(x) = ∫ f'(x)
1. Find The integration of f'(x) with the constant term
2. Substitute x by 1 and f(x) by π to find the constant term
3. Write the differential function f(x) and substitute x by 5 to find f(5)
∵ f'(x) =
+ 6
- Change the root to fraction power
∵
= 
∴ f'(x) =
+ 6
∴ f(x) = ∫
+ 6
- In integration add the power by 1 and divide the coefficient by the
new power and insert x with the constant term
∴ f(x) =
+ 6x + c
- c is the constant of integration
∵ 
∴ f(x) =
+ 6x + c
- To find c substitute x by 1 and f(x) by π
∴ π =
+ 6(1) + c
∴ π =
+ 6 + c
∴ π = 6.4 + c
- Subtract 6.4 from both sides
∴ c = - 3.2584
∴ f(x) =
+ 6x - 3.2584
To find f(5) Substitute x by 5
∵ x = 5
∴ f(5) =
+ 6(5) - 3.2584
∴ f(5) = 49.1
The value of f(5) is 49.1
