I need help with an Algebra question. The question is in the picture. Thank you &lt;3
olchik [2.2K]
The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is 0 \le t \le 165

-------------------------------

The range is 0 \le H \le 40000 since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.

in the following ordinary annuity interest is compounded with each payment and the payment is made at the end of the compounding
stealth61 [152]

Answer: $59313.58

Step-by-step explanation:

We know that formula we use to find the accumulated amount of the annuity ( ordinary annuity interest is compounded ) is given by :-

FV=A(\frac{(1+\frac{r}{m})^{mt})-1}{\frac{r}{m}}), where A is the annuity payment deposit, r is annual interest rate , t is time in years and n is number of periods.

Given : Annuity payment deposit :A= $4500

rate of interest :r= 6%=0.06

No. of periods : m= 1   [∵ its annual]

Time : t= 10 years

Now we get,

FV=(4500)(\frac{(1+\frac{0.06}{1})^{1\times10})-1}{\frac{0.06}{1}})\\\\\Rightarrow\ FV=(4500)(\frac{(1.06)^{10})-1}{0.06})\\\\\Rightarrow\ FV=(4500)(\frac{0.79084769654}{0.06})\\\\\Rightarrow\ FV=(4500)(13.1807949423)\\\\\Rightarrow\ FV=59313.5772407\approx59313.58 \ \

∴ the accumulated amount of the annuity= $59313.58

What's the difference between two whole number 1/2 percent of 36 and 30% of 10<br>​
AlexFokin [52]

Here, we proceed step by step, to obtain our answer,

\frac{1}{2}  % of 36 can be written as ,

0.5 % of 36 , which means,

100 % refers to 36, then

0.5 % refers to what,  thus, by cross multiplication we get,

0.5 % of 36 =  \frac{0.5 X 36}{100} = 0.18 ___(1), which can be expressed in whole numbers as 0.

Now, 30 % of 10 means,

100 % refers to 10, then

30 % refers to what,  thus, by cross multiplication we get,

30 % of 10 = \frac{30 X 10}{100} = 3 __(2)

From equations (1)  and (2),

the whole numbers that we obtain are 0 and 3, respectively,

Thus the difference between these two whole numbers is,

= 3 - 0 = 3.
