2700=2300(1+r)^5 solve for r Please show all work

Answers

Answer 1

Answer: $2700=2300(1+r)^5\ /:2300\n\n(1+r)^5= (27)/(23) \ \ \ \Rightarrow\ \ \ 1+r= \sqrt[5]{ (27)/(23)} \ \ \ \Rightarrow\ \ \ r= \sqrt[5]{ (27)/(23)} -1\n\n r= \sqrt[5]{ (27\cdot23^4)/(23^5)}-1= \frac{ \sqrt[5]{ 27\cdot23^4} }{23} -1= \frac{ \sqrt[5]{7555707} }{23} -1$

Answer 2

Answer: $2700=2300(1+r)^5\n \n (1+r)^5=(2700)/(2300)\n \n (1+r)^5=(27)/(23)\n \n \sqrt[5]{(1+r)^5}= \sqrt[5]{(27)/(23)}\n \n 1+r= 1.032\n \n r=1.032-1\n \n \boxed{r=0.032}$

Answers

Answer:

w = 24

Step-by-step explanation:

$(5w)/(8)$ = 15

Multiply both sides by 8.

5w = 15 × 8

= 120

Find w.

w = 120 ÷ 5

w = 24

Answer:

Step-by-step explanation:

Given : $(18x^3+12x^2-3x)/(6x^2)$

To Find: What is the coefficient of x in the division

Solution:

$(18x^3+12x^2-3x)/(6x^2)$

On Dividing we

Quotient = 3x+2

Remainder = -3x

So, coefficient of x in quotient = 3

Thus the coefficient of x in the division $(18x^3+12x^2-3x)/(6x^2)$ is 3

Hence Option A is correct

That would be A.... when you divide the trinomial in bracket by the $6x^(2)$ you will realize that the coefficient of the x is 3. If you want me to send a picture of the division please indicate.

Write a linear function with the values f(6)=8 and f(9)=3
*PLEASE HELP IM SO LOST*

Answers

Answer:

y = -5x/3 + 18

Step-by-step explanation:

The points can be written as;

(x,f(x))

where f(x) is same as y

So the points we have are;

(6,8) and (9,3)

We start by finding the slope or the line connecting the points

m = y2-y1/x2-x1 = (3-8)/(9-6) = -5/3

So now we have the general form of a linear equation as

y = mx + b

where m is slope and b is y intercept

We already have slope and we want to calculate y-intercept

Simply substitute one of the points

(9,3) in this case

9 for x and 3 for y

we have ;

y = -5x/3 + c

3 = -15 + c

c = 18

So the line equation is;

y = -5x/3 + 18
