ngles, which statement about x is true? A) x = 160, because 180 − (130 + 30) = 20 and 180 − 20 = 160 B) x = 20, because 130 + 30 = 160 and 180 − 160 = 20 C) x = 80, because 180 − 130 = 50 and 50 + 30 = 80 D) x = 340, because 130 + 30 = 160 and 160 + 180 = 340

If h(x)=(fog)(x) and h(x) = sqrt x+5, find g(x) if f(x) = sqrtx+2
Katen [24]

Answer: The value of g(x) is x+3.

Step-by-step explanation:

Since we have given that

h(x)=f\circ g(x)

Here,

h(x)=\sqrt{x+5}\\\\and\\\\f(x)=\sqrt{x+2}

We need to find the value of g(x):

f(x)=\sqrt{x+2}\\\\f(g(x))=\sqrt{g(x)+2}\\\\h(x)=\sqrt{g(x)+2}\\\\\sqrt{x+5}=\sqrt{g(x)+2}\\\\x+5=g(x)+2\\\\g(x)=x+5-2=x+3

Hence, the value of g(x) is x+3.

givi [52]

Answer:

  • 1) 4812 students
  • 2) 763 pounds
  • 3) $30906.76

Step-by-step explanation:

1)

  • Initial number = 2988
  • Rate of increase = 10%

<u>Number of students after 6 years:</u>

  • a_6 = 2988(1+0.1)^{6-1} = 4812

2)

  • Initial number = 1200
  • Rate of decrease = 14%

<u>Amount of gold after 4 years:</u>

  • a_4=1200(1-0.14)^3 = 763

3)

  • Initial number = 28000
  • Rate of increase = 2.5%

a)

<u>Salary after n years:</u>

  • a_n=28000(1+0.025)^{n-1} = 28000*1.025^{n-1}

b)

<u>Salary in the 5th year:</u>

  • a_5=28000*1.025^4 = 30906.76
