solve for n 50 points
a=p(1+r/n)^rn
Answer:
[tex]n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }[/tex]
Step-by-step explanation:
[tex]a=p(1+\frac{r}{n} )^{nt}[/tex]
[tex]\frac{a}{p} =(1+\frac{r}{n} )^{nt}[/tex]
[tex]\sqrt[nt]{\frac{a}{p}} =(1+\frac{r}{n} )[/tex]
[tex]\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )[/tex]
[tex]n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }[/tex]

Solve the problem and explain the steps taken. There are four students working on a project in math class. Miguel has completed 1/8 of the project, Gina has completed 13% of the project, Jatziry has completed 0.10 of the project, and Kwa has completed 19 of the project. Makw a list of students in order from least to greatest by the amount of the project they have completed.
Answer:
10%
12.5%
13%
19%
Step-by-step explanation:
First write all of the amounts as a percent.
1/8 = 12.5%
13%
.10 = 10%
19%
Then you can order them from least to greatest.
10%, 12.5%, 13%, and then 19%

Like term's coefficient are added in addition of algebraic terms. The simplified form of the given expression is [tex]x^3 + 8x^2 + 13[/tex]
What are like terms?Those terms which have same variables raised with same power.
For example, [tex]5t^3[/tex] and [tex]6t^3[/tex] are like terms since variable is same, and it is raised to same power 3.
For example [tex]x^3[/tex] and [tex]3x^4[/tex] are not like terms as the variables are same but powers aren't same.
What are coefficients?Constants who are in multiplication with variables are called coefficients of those variables.
When can we add or subtract terms of polynomial by their coefficient's addition or subtraction?Suppose we have
[tex]5x^2 + 6y[/tex]
Since those terms are not like terms, their coefficient won't be add and the expression we've got right now, is its simplest form and cannot be reduced more.
If we have, suppose,
[tex]4x + 5x^2 + 2x[/tex]
then we see that [tex]4x[/tex] and [tex]2x[/tex] are like terms, their coefficient can be added and thus, the simplified form would be
[tex](4+2)x + 5x^2 = 6x + 5x^2[/tex]
For the given case, the considered expression is simplified as:
[tex]= > (6x^2 - 3 + 5x^3) - (4x^3 - 2x^2 - 16)\\= 6x^2 - 3 + 5x^3 -4x^3 + 2x^2 + 16\\ = 5x^3 - 4x^3 + 6x^2 + 2x^2 - 3 + 16\\= (5-4)x^3 + (6+2)x^2 + 13\\= 1.x^3 + 8x^2 + 13 \\= x^3 + 8x^2 + 13[/tex]
(variables with 1 as coefficient is not written explicitly as 1 is factor of all measurements).
Sign multiply by
[tex]-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve[/tex]
where -ve, +ve are sign of operands and result.
Thus, the simplified form of the given expression is [tex]x^3 + 8x^2 + 13[/tex]

What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
What is the closure property of multiplication?A set is closed under an operation when we do that operation on the member of the set and we always get a set member.

Answer:
2/3
Step-by-step explanation:
Probability of choosing an eclair = 1/15
This means that there is 1 eclair in every 15 sweets.
As there are 3 eclairs, there are 3 x 15 = 45 sweets in total.
Now we can write an expression for the total number of sweets and solve for x:
Total number of sweets = 3 + (2x + 6) + x = 45
⇒ 3x + 9 = 45
⇒ 3x = 45 - 9
⇒ 3x = 36
⇒ x = 36 ÷ 3
⇒ x = 12
Now we have found x, we can determine the number of humbugs in the jar by substituting x = 12 into 2x + 6:
(2 x 12) + 6 = 30
So the probability the sweet is a humbug is 30 / 45 = 2/3

Also given that,
x = -2
So, to solve the above expression, you have to replace x with ( - 2 )
Let us solve.

Find 25% of 116 I don't know the answer
Answer:
29
Step-by-step explanation:
Let's set up an equation...
25%*116=x
We can first convert 25% to a fraction. We can convert any percentage into a fraction by simply putting the number over 100...
[tex]\frac{25}{100}*116=x[/tex]
We can simplify 25/100 by dividing the fraction by 25/25. Note we can only do this because 25/25 is equivalent to 1, therefore meaning we are dividing the fraction by 1.
[tex]\frac{1}{4}*116=x\\\frac{116}{4}=x\\x=29[/tex]

f (x) = 3x - 5 g (x) =2^x Find f^-1 (x)
Answer:
f^-1(x) = (x +5)/3
also = 1/3 x + 5/3
Step-by-step explanation:
Just to be clear, the ^-1 has nothing to do with negative exponents. It just unfortunately looks the same as a negative exponent.
Anyway, there's three basic steps. First write y instead of f(x). Then switch the x and y. Then solve for y.
f(x) = 3x - 5
write y in place of f(x).
y = 3x - 5
SWITCH x and y.
x = 3y - 5
SOLVE for y.
-3y + x = -5
-3y = -x - 5
y = (-x - 5)/-3
y = (x + 5)/3
OR
y = (1/3)x + 5/3
f^-1(x) = 1/3 x + 5/3

Given f(x) = 2x2 – x+ k, and the remainder when f(x) is divided by x – 1 is 3,
then what is the value of k?
Given :-
f(x) = 2x² - x + k .When f(x) is divided by (x-1) , the remainder is 3 .To Find :-
The value of k .Solution :-
Here we are given that ,
→ f(x) = 2x² - x + k
By Remainder Theorem , if f(x) is divided by x-a , then the remainder is f(a) .Hence here is f(x) is divided by x-1 , then the remainder will be f(1) . On substituting x = 1 , we have ,→ f(x) = 2x² - x + k
→ f(1) = 2(1)² - 1 + k
f(1) = 3 ,→ 3 = 2*1 -1 + k
→ 2 -1 + k = 3
→ k +1 = 3
→ k = 3-1
→ k = 2
Hence the value of k is 2 .
