Learning Task 1 An old woman is overweight. Her doctor told her to decrease 35 kilos. If she loss 11 kilos in the 1st week, 9 ki

navik [9.2K]

An arithmetic progression is a number sequence arranged in order, and having a common difference between successive terms

The time it will take the woman to lose 35 kilos is 5 weeks

The reason the above value is correct is as follows:

The given parameters are;

Weight the woman told her doctor to decrease = 35 kilos

Weight loss in the 1st week = 11 kilos

Weight loss in the 2nd week = 9 kilos

Weight loss in the 3rd week = 7 kilos

Required:

The time it will take the woman to lose 35 kilos

Solution;

The table of values is presented as follows;

$\begin{array}{|cc|c|}\mathbf{Week}&&\mathbf{Weight\ \ loss }\\&&\\1&&11\\2&&9\\3&&7\\4&&5\\5 &&3\\&& \\ Total \ weight \ loss&&35\end{array}$

From the above table, the common difference, between each successive weight loss is 2 kilos, therefore, on the 5th week, the weight loss will be 3 kilos (arithmetic progression)

Therefore number of the the total weight loss after 5 weeks is

35 kilos, therefore, if she continues losing weight at the given rate it will take 5 weeks to lose 35 kilos

Find the largest number which divides 870 and 720 exactly

mote1985 [20]

$870=29\times5\times3\times2$
$720=5\times3^2\times2^4$

$\mathrm{gcd}(870,720)=2\times3\times5=30$

The area of a rectangular region can be expressed as x2 +5x - 84 square units. If the width is x+12, what Is the length ?

posledela

Okay so we're given:

Area = x^2 + 5x -84
width = x +12
We need to find length, so for now, let's say length = L

We know Area = Length x Width so filling what we have into this equation...

Area = Length*width

x^2 +5x -84 = L*(x+12)

Divide both sides by (x +12) and you get...

(x^2 +5x-84)/(x+12) = L

Do that division and you get

L = x-7

Let me know if you need help with the polynomial division, there are lots of good videos on it on youtube!

how much would $600 be worth after 10 years, if it were invested at 4% interest compound continuously?

hichkok12 [17]

Use the compound-cont formula A = Pe^(rt):

A = $600*e^(0.04*10) = $600*e^0.4 = $624.49 (ans)

Solve this system by substitution. Y=-8x-23 Y=-5x-14

matrenka [14]

$set\ them\ equal\ to\ each\ other \\ -8x-23=-5x-14 \\ -3x-23=-14 \\ -3x=9 \\ x= \frac{9}{-3} \\ x=-3 \\ \\ plug\ in\ OG\ equation \\ y=-8x-23 \\ y=-8(-3)-23 \\ y=24-23 \\ y=1 \\ \\ \boxed {(-3,1)}$
