Answer:

Domain: (-∞, 1]

Range: (-∞, 3]

Step-by-step explanation:

The function starts at point (1, 3) and goes to the left and down forever.

Answer:

Domain: $(-\infty, 1]$

Range: $(-\infty, 3]$

Step-by-step explanation:

The domain of a function represents the range of x-values that are part of the function, read left to right. We can see that the function goes forever to the left and stops at $x=1$ when we read left to right. Therefore, the domain of this function is $\boxed{(-\infty, 1]}$ .

The point at $x=1$ is a filled-in solid dot so it is included as part of the function. Use square brackets to denote inclusive.

The range of a function represents all y-values that are part of the function, read bottom to top. The function continues down forever and stops at $y=3$ when read bottom to top. Therefore, the range of this function is $\boxed{(-\infty, 3]}$ . Similar to the domain, we use a square bracket on the right to indicate that $y=3$ is included in the function. If the dot was not filled-in, then we would use a parenthesis to indicate that $y=3$ would not be part of the function.

Need help please its my last question

Nesterboy [21]

Given:

Radius of circle = 12 units

Area of sector = 24π sq. units.

Central angle = x

To find:

The value of x.

Solution:

We have,

$r=12$

$A=24\pi$

$\theta = x$

We know that, area of a sector is

$A=\dfrac{\theta }{360^\circ}\pi r^2$

Where, $\theta$ is central angle, r is radius.

$24\pi=\dfrac{x}{360^\circ}\pi (12)^2$

$24\pi=\dfrac{x}{360^\circ}\pi (144)$

$\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}$

$\dfrac{1}{6}=\dfrac{x}{360^\circ}$

Multiply both sides by 360 degrees.

$\dfrac{1}{6}\times 360^\circ=x$

$60^\circ=x$

The value of x is 60 degrees.

Therefore, the correct option is A.

Given: f(n) = 3n-5 and g(n) = 2n-1<br>Find: (fog)(5

laiz [17]

Answer:

Step-by-step explanation:

So we have the two functions:

$f(n)=3n-5\text{ and } g(n)=2n-1$

And we want to find (fog)(5). This is the same as:

$(f\circ g)(5)=f(g(5))$

So, find g(5) first:

$g(5)=2(5)-1\\$

Multiply and subtract:

$g(5)=10-1=9$

So, we can substitute:

$f(g(5))=f(9)$

Find the value:

$f(9)=3(9)-5$

Multiply and subtract:

$f(9)=27-5=22$

So:

$(f\circ g)(5)=22$

And we're done!

En una ciudad se registró una temperatura de 12°c bajo cero a las 3:00 am si a las 7:00am del mismo dia la temperatura era tres

hjlf

Answer:

24°c

Step-by-step explanation:

Cuando se dice que la temperatura esta "mayor" significaria que esta aumentando y entorno subiendo a ser mas caliente. Siendo este el caso, si la temperatura a las 3:00 estaba a 12c bajo cero entonces a las 7:00 estaria a 24c. Esto es por que un aumento de tres vecesseria un aumento de 36 grados (12*3). 12c grados bajo cero seria un numero negativo y si sumamos estos numeros nos daria 24c grados.

-12 + 36 = 24

Malik grills a steak 45 minutes longer than he grills a serving of fish. The fish takes twice as long as the asparagus to grill.

stellarik [79]

Vasellasar26,

Penso che tu parli italiano, quindi ecco la risposta alla domanda in italiano. Malik griglia una bistecca 45 minuti in più rispetto a u.na porzione di pesce. Il pesce impiega il doppio del tempo per grigliare gli asparagi. Malik griglia i pomodori tagliati a metà per 3 minuti, che è 3 minuti in più rispetto a quando griglia gli asparagi. 3 33 Questa domanda è composta da 3 parti. Assicurati di completare tutte le parti. A Indicazioni: digita la tua risposta nella casella. Scrivi un'espressione che rappresenti il tempo durante il quale Malik griglia la bistecca se gli asparagi grigliano x minuti.
