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

It decreased by 25% every year.
if you multiply a number by a decimal you will get a smaller number than you originally had. for example, if you multiply 95 by .75 you will get 71.25 it is decreasing but only 25%
Answer:
293.776 yd
Step-by-step explanation:
3A=3L×w A=10×12.2=122
A=12.2×7.04=85.888
A=12.2×7.04=85.888
3A=122+85.888+85.888=293.776
From the diagram:
AB + BC = AC
we know that AC = 42, therefore:
AB + BC = 42 ..............> equation I
We know that the ratio AB:BC is 3:4. This means that:
AB/BC = 3/4
4AB = 3BC
AB = (3/4) BC ...............> equation II
Substitute by equation II in equation I to get BC as follows:
(3/4) BC + BC = 42
1.75 BC = 42
BC = 24Substitute with the value of BC in equation II to get AB as follows:
AB = (3/4) * 24 = 18
