We have been given a graph of function g(x) which is a transformation of the function f(x)=3^x

Now we have to find the equation of g(x)

Usually transformation involves shifting or stretching so we can use the graph to identify the transformation.


First you should check the graph of f(x)=3^x

You will notice that it is always above x-axis (equation is x=0). Because x-axis acts as horizontal asymptote.

Now the given graph has asymptote at x=-2

which is just 2 unit down from the original asymptote x=0

so that means we need shift f(x), 2 unit down hence we get:

y=3^x


but that will disturb the y-intercept (0,1)

if we multiply 3^x by 3 again then the y-intercept will remain (0,1)

Hence final equation for g(x) will be:

g(x)=3(3^x)-2

Bottom Side Surface Area:

(24 inches + 24 inches + 24 inches) * (30 inches)

= 72 inches * 30 inches

= 2160 inches squared


--------

Top Side Surface Area:

24 inches * 30 inches

= 720 inches squared

--------

Length of the diagonal (D) which needs to be measured:

*Use Pythaogras's theorem...

24^2 + 10^2 = D^2

D=√(24^2+10^2)

D=26 inches

------------

Measure the surface area of the two ramps:

26 inches * 30 inches * 2

= 1560 inches squared

-----------

Total surface area:

2160 inches squared + 720 inches squared + 1560 inches squared

= 4440 inches squared

---------

Answer:

4440 square inches

Un rectangulo tiene area de 15/40 cm cuadrados y sabemos que uno de sus lados mide 5/8 cuanto medira el otro lado
GaryK [48]

Queremos encontrar la medida de un lado de un rectangulo, dado que conocemos la longitud del otro lado y el area del rectangulo.

Veremos que el otro lado del rectangulo mide 3/5 cm

Sabemos que para un rectangulo de largo L y ancho W, el area esta dada por:

A = L*W

En este caso sabemos que el area es igual a (15/40) cm^2.

Y sabemos que uno de sus lados (digamos que es el ancho) mide (5/8) cm.

Entonces podemos reemplazar eso en la ecuación del area:

(15/40) cm^2 = L*(5/8) cm.

Ahora podemos resolver esto para L.

L = (15/40 cm^2)/(5/8 cm) = (15/40 cm^2)*(8/5 cm^-1)

L = 3/5 cm

El otro lado del rectangulo mide 3/5 cm

8_murik_8 [283]

Answer:

read step by step

Step-by-step explanation:

6 is +4.

19, 23, 27, 31

7 is all perfect square numbers

25, 36, 49, 64

8 is x2.

32, 64, 128, 256

9 is each number multiplied by the next. ex: 1x2=2, 2x3+6, 3x4=12

so the next few would be 30, 42, 56, 72
