Find f(g(x)) f(x)=2x-5 , g(x)=4x+3

Mathematics
1 answer:
hichkok12 [17]2 years ago
4 0

Set the composite results function.

\boldsymbol{f(g(x)) }

Evaluate f(g(x)) by substituting the value of g into f.

\boldsymbol{2(4x+3)-5}

Simplify each term.

Apply the distributive property.

  • \boldsymbol{f(4x+3)=2(4x)+2\cdot3-5 }

Multiply 4 by 2.

  • \boldsymbol{f(4x+3)=8x+2\cdot3-5 }

Multiply 2 by 3.

  • \boldsymbol{f(4x+3)=8x+6-5 }

Subtract 5 from 6.

  • \boldsymbol{f(4x+3)=8x+1 }

\red{\boxed{\green{\boxed{\boldsymbol{\purple{Pisces04}}}}}}

Please please help!!!! According to the probability distribution below, what is the expected value of X? X 0 1 2 3 4 5 P(X) 0.3
Novay_Z [31]

Answer:

D.) The expected value is 1.78

Step-by-step explanation:

The expected value of a probability distribution is evaluated using the formula.

Expected Value, E(X)=\sum^{n}_{i=1}x_iP(x_i)

Therefore, from the given probability distribution, we have:

E(X)=(0*0.3)+(1*0.2)+(2*0.16)+(3*0.2)+(4*0.04)+(5*0.1)

E(X)=1.78

The Expected value of X is 1.78.

The correct option is D.

Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x) Dawn writes 800 pages in 80 da
lilavasa [31]
Given function f(x) which is described by "<span>Dawn writes 800 pages in 80 days".

From this function we can notice that Dawn writes 0 pages in 0 days, (i.e. the initial point of the function is point (0, 0).

Recall that the slope, m, of a line passing through points:
(x_1,y_1) and (x_2,y_2)
is given by
m= \frac{y_2-y_1}{x_2-x_1}

Function f(x) passes through points (0, 0) and (80, 800).

Thus the slope of function f(x) is given by
m= \frac{800-0}{80-0} = \frac{800}{80} =10


Give function g(x), passing through points (2, -6) and (4, 12), the slope is given by
m= \frac{12-(-6)}{4-2} = \frac{12+6}{2} = \frac{18}{2} =9

It can be seen that the slope of f(x) and the slope of g(x) are close.

PLEASE HELP! I do not understand as to what they are asking for me to do and how to do it.
Ymorist [56]

Answer:

<em>1 cm^2 : 9 m^2</em>

Step-by-step explanation:

The scale factor of an area is the square of the scale factor of a length.

The scale for lengths is 1 cm : 3 m.

You now square that scale to get the scale of the areas.

Scale of areas:

(1 cm)^2 : (3 m)^2

1 cm^2 : 9 m^2
