Step-by-step explanation:

principal = 18000

Time = 3 yrs

Rate. = 8%.

CI. = ?

Now

CI = p ( 1+ R÷ 100) ^T

CI = 18000( 1+ 8÷ 100 ) ^ 2

CI = 20995.2

Hope it's is Right :-)

Answer:

interest ( I ) , principal ( P ), Time ( T ) , Rate ( R )

P = I×T×R

100

P = 18,000×2×8

100

= 18,000×16

100

so two zero cancel other two zero living

= 180×16 = 180 × 16

= 180 × 16

P = 2880

What ere the coordinates of the point on the directed line segment from (-1,7) to (7,7) that partitions the segment into a ratio

djverab [1.8K]

Answer:

$(\frac{37}{11},\frac{77}{11} )$

Step-by-step explanation:

Given two points are (-1,7) and (7,7).

We are told to find a point which is in between them at a ratio of 6:5.

Formula for calculating a point at distance of ratio m:n is given by

$(\frac{mx2+nx1}{m+n} ,\frac{my2+ny1}{m+n} )$

where $(x1,y1),(x2,y2)$ are the inital and final points.

$(x1,y1)=(-1,7)\\\\(x2,y2)=(7,7)$

also m:n=6:5 ,

by substituting all the values we get,

$(\frac{6*7+5*-1}{11} ,\frac{6*7+5*7}{11} )$

$(\frac{37}{11},\frac{77}{11} )$

Suppose f '(x) = xe^−x^2

iogann1982 [59]

<h3>Answers:</h3>

(a) The function is increasing on the interval (0, infinity)
(b) The function is decreasing on the interval (-infinity, 0)

=======================================================

Explanation:

You should find that the derivative is entirely negative whenever x < 0. This suggests that the function f(x) is decreasing on this interval. So that takes care of part (b).

The interval x < 0 is the same as -infinity < x < 0 which then translates to the interval notation (-infinity, 0)

Similarly, you should find that the derivative is positive when x > 0. So the function is increasing on the interval (0, infinity)

At a sale this week, a desk is being sold for 128.80. This is a 72% discount from the original price. What is the original price

wel

Answer:

$460

Step-by-step explanation:

If the 128.80 is the price of the desk after a 72% discount, it means that 128.80 is 100-72=28% of the original price.

From here, we can divide 128.80 by 28 to find what 1% of the price is then multiply the value by 100 to find 100%, or the original price.

128.80/28 = 4.6

4.6 x 100 = 460

Original price = $460

Hope this helped!
