F( x) = 3 x + 2 and g( x) = 2 x + 5. Find f ∘ g(5)<br><br> Please show your work
kolbaska11 [484]

Answer:

f ∘ g(5) = 47

Step-by-step explanation:

We are given the following functions:

f(x) = 3x + 2, g(x) = 2x + 5

Composite function:

The problem asks their composite function at x = 5. So

f \circ g = f(g(x)) = f(2x + 5) = 3(2x + 5) + 2 = 6x + 15 + 2 = 6x + 17

f(g(5)) = 6(5) + 17 = 30 + 17 = 47

We have that f ∘ g(5) = 47

Julian fully simplifies this polynomial and then writes it in standard form. 4x2y2 – 2y4 – 8xy3 + 9x3y + 6y4 – 2xy3 – 3x4 + x2y2
Rasek [7]

  <u>4x²y²</u> <em>- 2y⁴</em> - 8xy³ + 9x³y <em>+ 6y⁴ </em>- 2xy³ - 3x⁴ <u>+ x²y²</u>

= <u>5x²y²</u> <em>+4y⁴</em> - 10xy³ + 9x³y - 3x⁴      <em>combined like terms</em>

= -3x⁴ + 9x³y  + 5x²y²  - 10xy³ + 4y⁴     <em>descending exponent order based on "x"</em>

If Julian wrote his list in descending order based on "y", then the order would be reversed.

Answer:  4y⁴

Find the area of the polygon.
svetlana [45]
This is a trapezoid and the trapezoid formula is b1 plus b2/ 2 times height. 

17 plus 5 is 22. Divided by 2 is 11. 

Now, we have to multiply 11 by the height : 5. 

11 times 5 is 55 and that is your area. 55 units squared.
