Answer:

-4

Step-by-step explanation:

Let's write the expression in math language and then we evaluate it if the number is -3.

For us, the "number" will be represented with an x. It says that the number is tripled, so we have 3*x.

But we need five more than that number tripled, so we have 3*x + 5.

Now we evaluate it if the number is -3. For that, we just replace the x with -3:

3*(-3) + 5 = -9 + 5 = -4

Evaluate the expression described below if the number is –3.
Five more than a number tripled. 

Solution: 

the number tripled is 3(-3) = -9 

Five more than the number tripled is: 5 - 9 = -4

After two consecutive years of 5% rates of return, what rate of return in the third year will produce a cumulative gain of 16%?

murzikaleks [220]

Using decimal multipliers, it is found that a rate of return of 5.2% in the third year will produce a cumulative gain of 16%.

The decimal multiplier for a increase of a% is given by:

$M = \frac{100 + a}{100}$

In this problem, two increases of 5%, thus:

$M = \frac{100 + 5}{100} = 1.05$

Another of x, that we want to find, and the result is a increase of 16%, thus:

$M = \frac{100 + 16}{100} = 1.16$

The three increases(5%, 5% and x%) result in a increase of 16%, thus:

$1.05(1.05)(x) = 1.16$

$x = \frac{1.16}{(1.05)^2}$

$x = 1.052$

1.052 - 1 = 0.052

A rate of return of 5.2% in the third year will produce a cumulative gain of 16%.

For what values of a and m does f(x) have a horizontal asymptote at y = 2 and a vertical asymptote at x = 1? f(x)=2x^m/x+a {a =

iVinArrow [24]

Answer:

See below

Step-by-step explanation:

$f(x)=\frac{2x^{m} }{x+a}$

$f(x)=\frac{2x^{1} }{x-1}$

If x=1, then 1-1=0, which implies a vertical asymptote at x=1 since dividing by 0 is undefined.
