Find the domain of fg

2 answers:

7 0

We have the following functions:
f (x) = x ^ 2 + 1
g (x) = 1 / x
Multiplying we have:
(f * g) (x) = (x ^ 2 + 1) * (1 / x)
Rewriting:
(f * g) (x) = ((x ^ 2 + 1) / x)
Therefore, the domain of the function is given by all the values of x that do not make zero the denominator.
We have then:
All reals except number 0
Answer:
b. all real numbers, except 0

Chandler is walking 1/16 km every 10 minutes. How many kilometers will he walk in 1 hour?!

SashulF [63]

Answer:

$\frac{3}{8} or\ 0.375\ km$

Step-by-step explanation:

Given: Chandler walk 1/16 km every 10 minutes.

First, lets find how many 10 minutes in one hours or convert minutes in hours.

∴ Time= $\frac{60}{10} \ h$

Now, finding kilometres travelled in 1 hour.

Distance travelled= $\frac{1}{16} \times \frac{60}{10} = \frac{1}{16} \times 6$

Distance travelled = $\frac{3}{8}$

Converting $\frac{3}{8} \ km$ into decimal will have 0.375 km.

∴ $\frac{3}{8} or\ 0.375\ km$ will chandler walk in 1 hour.

Answer:

8 < x < 16

Step-by-step explanation:

Consider an angle slightly less than 180 between the 4 and 12 ft sides. The measure between the 2 end points is slightly less than the total of the two sides. So the greatest length is 16.

Consider an angle slightly more than 0 between the 4 and 12 ft sides. The measure between the 2 end points is slightly more than the difference between the two sides. So the lowest length is 8.

Tanzania [10]

Answer:

Ans. you should deposit each month to end up with $38,000 the amount of $533.33 every month for 5 years at a APR of 6.5%

Step-by-step explanation:

Hi, first we have to convert all the data to monthly basis, that is, 5 years (5*12=60 months) and the rate of 6.5% APR offered by the bank (Monthly rate = 0.065/12=0,005666667 or 0.5667% monthly)

With that in mind, we need to solve for "A" the following equation.

$FV=\frac{A((1+r)^{n}-1) }{r}$
