Answer:

4 : 25pm

Step-by-step explanation:

If the movie ended at 7:05p.m, and the movie is as long as 2 hours 40 minutes, therefore the starting time is 2 hours 40 minutes earlier than the ending time

Therefore

7:05 - 2 hours and 40 minutes

= 4 : 25pm

Which statement correctly describes the end behavior of f(x)=ax+b, where a and b are positive numbers?

sergij07 [2.7K]

Answer:

The correct option is 2.

Step-by-step explanation:

The given function is

$f(x)=ax+b$

Where, a and b are positive numbers.

The given function is the slope intercept form of a linear function. Where a is the slope and b is y-intercept.

Since slope is positive therefore function approaches to infinity as x approaches to infinity and function approaches to negative infinity as x approaches to negative infinity.

It is also proved by using limits.

$lim_{x\rightarrow \infty}f(x)=lim_{x\rightarrow \infty}(ax+b)$

Apply limits.

$lim_{x\rightarrow \infty}f(x)=a(\infty)+b=\infty$

Similarly,

$lim_{x\rightarrow -\infty}f(x)=lim_{x\rightarrow -\infty}(ax+b)$

Apply limits.

$lim_{x\rightarrow -\infty}f(x)=a(-\infty)+b=-\infty$

Therefore option 2 is correct.

$f(x)\rightarrow \infty \text{ as }x\rightarrow \infty$

$f(x)\rightarrow -\infty \text{ as }x\rightarrow -\infty$

a circle is centered at (-4,9)and has a radius of 11. what is the equation of the circle. use x and y

Sholpan [36]

Answer:

(x + 4)^2 + (y-9)^2 = 121

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k) ^2 = r^2 where (h,k) is the center and r is the radius

(x - -4)^2 + (y-9)^2 = 11 ^2

(x + 4)^2 + (y-9)^2 = 11 ^2

(x + 4)^2 + (y-9)^2 = 121

What division statements have a quotient of 20

Jlenok [28]

Answer:

In the example, 20 is the dividend, five is the divisor, and four is the quotient. Unlike the other basic operations, when dividing natural numbers there is sometimes a remainder that will not go evenly into the dividend; for example, 10 ÷ 3 leaves a remainder of one, as 10 is not a multiple of three.
