I hope I read these correctly....not that easy...u got weird looking x's and ur 4's can almost pass for 6's
Answer:
1050
Step-by-step explanation:
We can use a ratio to solve
First find how many jam
210 - 189 =21
We want to find how many jam for 10500 printed
21 jam x jam
----------- = ----------------
210 printed 10500 printed
Using cross products
21 * 10500 = 210x
Divide each side by 210
21*10500/210 =x
1050=x
Here’s the answer and how i worked it out step by step. hope this helps :)
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
