stephen invests £7500 in an account which pays 5.5% compound interest per annum. Stephen has to pay 20% tax on the interest each
garri49 [273]
Interest earned
7,500×0.055
=412.5
Deduct tax
412.5−412.5×0.2
=330
Add the remaining interest
330+7,500
=7,830
Calculate interest earned in the second year
7,830×0.055
=430.65
Deduct tax
430.65−430.65×0.2
=344.52
Add the remaining interest
344.52+7,830
=8,174.52. ...answer

Point I is on line segment HJ.Given IJ= 2 and HJ=12, whats HI
Zolol [24]

The value of HI for the given line segment will be 10 units.

<h3>What is a line segment?</h3>

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given the line segment HJ

IJ = 2 units

HJ = 12 units

Since,

HJ = HI + IJ

HI = HJ - IJ

HI = 12 - 2

HI = 10 units.

Hence "The value of HI for the given line segment will be 10 units".

The national catch of Atlantic Cod has been declining in the past few decades. We can model this decline with the equation y = −
suter [353]
Y = -.003x²<span> + .120x + 1.909
</span>Standard form of a parabola is y = ax² + bx + c. The x coordinate of the vertex can be found with -b/2a.
-.120/(2 × -.003) + 20
So the max is at 1950 + 20 because x is years after 1950. Which is 1970.
To find when y will be 0, use the quadratic equation x = [-b +/- √(a² - 4ac)]/2a. +/- means plus or minus because I can't type the actual symbol.
x = [-.120 +/- √(-.003² - 4(-.003)(1.909))]/2(-.003)  Plug in info
x = [-.120 +/- √(.000009 - 4(-.005727))]/-.006
x = [-.120 +/- √(.000009 + .022908)]/-.006
x = [-.120 +/- √(.022917)]/-.006
x=-.120/-.006 +/- √(.022917)/-.006
x = 20 +/- <span>.15138361866/-.006
x = 20 +/- -</span><span>25.2306031108
Because it is plus or minus you split it and do both.
x = 20 - </span>-25.2306031108     x = 20 + -25.2306031108<span>
x = </span>45.2306031108             x = -<span>5.23060311077
so y is 0 when x is 45.2306031108 because there is no such thing as negative time so it can't be the other one. So the answer is 1995 because you add 45 to 1950.
Since the max is at 1970, it is increasing from 1950 to 1975 and decreasing from 1975 to 1995.

Sorry I took so long, I had to look up how to do it because I couldn't remember.</span>
