PLEASE HELP!!!<br> Please help me answer the questions that are circled, I really need help!

Answer:

Here:

Step-by-step explanation:

23. f(x) = \sqrt{x} and g(x) = x^2-5x

24. f(x) = x^2 and g(x) = x^3+1

28. f(x) = e^x and g(x) = sinx

29. f(x) = cosx and g(x) = \sqrt{x}

Basically, you try to find a function contained inside a function if that makes sense. For example in question 23, g(x) itself is a function =  x^2-5x. Same with f(x) = \sqrt{x} . In this case, when we try to fo f(g(x)), we are basically replacing x in the f(x) function by the equation in g(x). Hope this makes sense.

Answer:

Step-by-step explanation:

volume  of cylinder = πr²h = π(5²)(16) ≅ 1256 cm³

volume of cone = ⅓πr²h = ⅓π(3²)12 ≅ 113.04 cm³

volume of air space = 1256 - 113.04 = 1143.96 cm³

a_sh-v [17]

Answer:

(-3,-1.5)

Step-by-step explanation:

The two points are: (-2,1) & (-4,-4)

x =  \frac{ - 2 - 4}{2}  =  - 3 \\  \\ y =  \frac{1 - 4}{2 }  =  -  \frac{3}{2}  =  - 1.5

Answer:

Please find attached , the filled in boxes

The y-intercept is (0, 4)

Step-by-step explanation:

The given function is g(x) = 4 \times (0.6)^x

The values of x are given as -10, -1, 0, 1, 2, 8

The values of g(x) are

g(-10) = 4 × 0.6⁽⁻¹⁰⁾ = 4 × (3/5)⁽⁻¹⁰⁾ = 4 × (5/3)⁽¹⁰⁾ = 661.53

g(-1) = 4 × 0.6⁽⁻¹⁾ = 4 × (3/5)⁽⁻¹⁾ = 4 × (5/3)⁽⁽¹⁾ = 20/3 =

g(0) = 4 × 0.6⁽⁰⁾ = 4 × (3/5)⁽⁰⁾ = 4 × 1 = 4

g(1) = 4 × 0.6⁽¹⁾ = 4 × (3/5)⁽¹⁾ = 12/5 = 2.4

g(2) = 4 × 0.6⁽²⁾ = 4 × (3/5)⁽²⁾ = 36/25 = 1.44

g(8) = 4 × 0.6⁽⁸⁾ = 4 × (3/5)⁽⁸⁾ = 0.0672

The y intercept is given at the point x = 0 which is g(0) = 4

The y-intercept is g(0) = 4
