Answer:

f is continuous at a = -5.

Step-by-step explanation:

We have given a function.

f(x)  = 5x+5

We have to check continuity of function at a  = -5.

From definition of continuity,

If f is continuous at x = a

\lim_{x \to a} f(x)= f(a)

Putting x  = a = -5 in given function ,we have

f(-5) = 5(-5)+5 = -25+5

f(-5) = -20

\lim_{x\to-5} f(x) =5(-5)+5

\lim_{x \to-5}f(x) = -20

Hence, \lim_{x \to-5} f(x)= f(-5)

f is continuous at a = -5.

ANSWER

lim_{x \to  - 5}(f(x))  = f( - 5)

EXPLANATION

If f(x) is continuous at

x = a

Then,

lim_{x \to a}(f(x))  = f(a)

The given function is

f(x) = 5x + 5

f( - 5) =  5( - 5) + 5

f( - 5) =  - 25 + 5 =  - 20

lim_{x \to  - 5}(f(x))  = 5( - 5) + 5

lim_{x \to  - 5}(f(x))  =  - 20

Since,

lim_{x \to  - 5}(f(x))  = f( - 5)

The function is continuous at

x =  - 5

Answer:

<u>The correct answer is A.  A long-term investor, who wishes to hold onto the house for an extended period and rent it out in  the meantime.</u>

Step-by-step explanation:

This kind of investment is particularly attractive for long-term investors that are seeking for a predictable and steady return and that are not looking for a short-term big shot. As it is mentioned in the description, for taking full advantage the investor knows in advance that the property will also be rented while it increases its value.

The height of a rocket a given number of seconds after it is released is modeled by h (t) = negative 16 t squared 32 t 10. What
V125BC [204]

The variable t represents the number of seconds that have passed after the release of the rocket.

<h3>Function</h3>

The function can be defined as an expression that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The height of a rocket a given number of seconds after it is released is modeled by,

h(t) = 6t^2 + 32t + 10

As given in the above function, h (height) is the dependent variable which depends on the number of seconds t after the rocket is released (independent variable).

Hence we can conclude that the variable t represents the number of seconds after the rocket has been released.

To know more about the function, follow the link given below.

In a 30 degree, 60 degree, 90 degree triangle shortest side is 9. Find the lengths of the other sides
Inga [223]

Answer:

To find the second-shortest side we'll multiply 9 by √3 which is 9√3 and for the hypotenuse we'll do 9 * 2 = 18.
