Step-by-step explanation:
f(3)=?
f(x)=2x+5
put x=3,
f(3)=2(3)+5=6+5=11
------------
g(2)=?
g(x)=x^2-3
put x=2,
g(2)=2^2-3=4-3=1
-----------------
g(f(-1))=?
g(x)=x^2-3
and f(-1)=2(-1)+5= -2+5=3
so g(f(-1))=3^2-3=9-3=6
----------------
f(g(-1))=?
f(x)=2x+5
g(x)=g(-1)=(-1)^2-3=1-3= -2
f(g(-1))=2(-2)+5= -4+5=1
----------------
g(f(x))=?
g(x)= x^2-3
put x=f(x),
g(f(x))=f(x)^2-3=(2x+5)^2-3=4x+25+20x-3=24x+25
Let's make an equation.
19,000x=24,320
This equation shows the percentage increase, which is x. Once we have x, we need to subtract 1 from it since in the equation the 1 shows that it's increeasing. All we need to do is divide both sides by 19,000.
24,320÷19,000
1,28-1=0.28; we need to multiply by 100 to find the increase.
0.28×100=28
So, the percentage increase is 28%.
Exponent rule : a^-b = 1 / (a^b)
1/9 ^-3 =
1 / (1/9^3) =
1 / (1^3) /(9^3) =
1 / (1/729) =
1 * 729/1 =
729
ur answer is B
The digits after the decimal separator are, in order, tenths, hundreths and thousandths. So, your number is composed by:
- 1 unit
- 0 tenths
- 0 hundreths
- 2 thousandths
So, you would call this name "one and two thousandths"
What’s the question here ????
