115 times 0.8 because he already spent 0.2. 115 x 0.8 = 92
So $92 left to spend
Hope this helped
Answer:
Step-by-step explanation:
1, Find (g-f)(x)
we know (g-f)(x) = g(x) - f(x) = ( 5x -2) -( 2x^2 +3x +6)
= 5x -2 - 2x^2 - 3x - 6
= -2x^2 + 2x -8
So the function (g-f)(x) = - 2x^2 + 2x - 8
2, Find (fg)(x)
we know that (fg)(x) = f(x) * g(x)
= (2x^2 +3x +6 ) *( 5x -2)
= 5x* (2x^2 +3x +6 ) - 2*(2x^2 +3x +6 )
= 10x^3 + 15x^2 +30x -4x^2 -6x - 12
= 10x^3 + 11x^2 + 24x - 12
The answer is (fg)(x)= = 10x^3 + 11x^2 + 24x - 12
Different parallelograms require different ways of solving so theorems tell you how each parallelogram can be solved
The value of the real life expression is, simple interest = $12.5
<h3>How to simplify this real life expression and show unit analysis?</h3>
The real life expression is given as:
simple interest = ($100) (0.05/year) (2.5 years
Divide 1 year by 1 year
simple interest = ($100) (0.05) (2.5)
Rewrite the equation as a product of factors
simple interest = ($100) * (0.05)* (2.5)
Evaluate the product of 0.05 and 2.5
simple interest = ($100) * 0.125
Evaluate the product of $100 and 0.125
simple interest = $12.5
Hence, the value of the real life expression is, simple interest = $12.5
