Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 35x + 25
g(x) = 22x + 18
f(4) is <em>x</em> = 4 for function f(x)
g(10) is <em>x</em> = 10 for function g(x)
<u>Step 2: Find Function Values</u>
<em>f(4)</em>
- Substitute in <em>x</em> [Function f(x)]: f(4) = 35(4) + 25
- Multiply: f(4) = 140 + 25
- Add: 165
<em>g(10)</em>
- Substitute in <em>x</em> [Function g(x)]: g(10) = 22(10) + 18
- Multiply: g(10) = 220 + 18
- Add: g(10) = 238
<u>Step 3: Evaluate</u>
- Substitute in function values: 5(165) + 2(238)
- Multiply: 825 + 476
- Add: 1301

Answer: 50000
Step-by-step explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Rules for significant figures:
Digits from 1 to 9 are always significant and have infinite number of significant figures.
All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.
All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.
All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.
All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.
Thus 52961 when rounded off to one significant figure will be 50000.
