I dont know what to do for tis
kap26 [50]

Answer:

is this by any chance about simultaneous equations? If so,

Step-by-step explanation:

Step 1 is telling us to decide on whether x and y should be the unknown. For instance, you want x to be the unknown, so u solve for x.

Step 2 is telling us to write equations with x and y.

For example,

7x + 5y = 12

7x - 2y = 9

This may not be accurate but it is an equation.

Step 4 is telling us to check whether the solution is accurate or not. For instance, we say 7 is x. so we substitude 7 into the original equation to see whether the answer we found is correct.

For step 5, im not really sure.

hope this helps though???

A bank made a farmer loan of $1,000 at 14% for 3 years compounded annually. Find the future value and the compound interest paid
Anna11 [10]

Answer:

Principal =  $1,000

Rate of interest = 14% = 0.14

Time = 3 years

A= P(1+r)^t

A = Amount or future value

P = Principal

r = rate of interest in decimals

t = time

Substitute the values in the formula

A= 1000(1+0.14)^3

A=1481.544

Future Value is $1481.544

Compound interest = Amount - Principal = $1481.544- $1000 = $481.544

Formula of simple interest : SI =\frac{P \times R \times T}{100}

Substitute the values :

SI =\frac{1000 \times 14 \times 3}{100}

SI =420

So, Simple interest = $420

Compound interest - Simple interest

= $481.544- $420

= $61.544

So, Compound Interest is $61.544 more than simple interest.

The equation R=10a-20 represents the revenue R (in dollars) you make by spending A dollars on advertising. You revenue totaled $
timurjin [86]
R = 10a - 20
ur revenue totaled 110...so R = 110

110 = 10a - 20
110 + 20 = 10a
130 = 10a
130/10 = a
13 = a <== so u spent $13 on advertising

Consider the volume of the region shown below, which shows a right circular cone with top radius 3 cm and height 10 cm. We have
koban [17]
I have the same problem here with a slight change in the given values:

radius is 2 & height of 6 indicates the bounding line is y = 3 x---> x = y / 3.... 

<span>thus the [ π radius ² thickness ] yields π (y² / 9 ) <span>dy ,</span> y in [ 0 , 6 ] for the volume... </span>

a Riemann sum is then : y_i = 0 + i [ 6 / n ] = 6 i / n , i = 1,2,3...n and do a right side sum 

<span>π Σ { i = 1,2,3..n } [ 36 i² / 9 n² ] [ 6 / n ]
</span>
I hope my guide has come to your help. God bless and have a nice day ahead!
