Answer:

l( longer side ) = 12cm

S (shorter side) =9cm

D's( distance between the shorter side). ( It is also the height. I hope you got the clue…)

Anyway,

Area=9X8=72cm^2

Distance of the longer sides is

Area/the length of the longer side

72/12=6cm…

Distance between the longer sides is 6cm

Hope this helps…

How long it will take 2000$ to double if it is invested at 6% interest compounded semi annually

emmainna [20.7K]

Answer:

Number of year = 11.725 year (Approx.)

Step-by-step explanation:

Given:

Amount invested = $200

Interest rate = 6% (compounded semi annually)

Future value = 2 x Amount invested

Find:

Number of year

Commutation:

Future value = 2 x Amount invested

Future value = 2 x 200

Future value = $400

Number of year (Semi-annual) = 2n

Interest rate (Semi-annual) = 6% / 2 = 3%

So.

A = P[1+r]ⁿ

400 = 200[1+3%]²ⁿ

2 = [1.03]²ⁿ

n = 11.725 year

Number of year = 11.725 year (Approx.)

Only answer if your 100% sure<br><br><br> What equation is shown by the graph

devlian [24]

Hello!

The equation for a line is y = mx + b

m is the slope
b is the y-intercept

The y-intercept is -3

y = mx - 3

To find the slope you count how many times up and over it goes from point to point

It goes up one over one

$y = \frac{1}{1} x - 3$

Simplify

The answer is y = x - 3

Hope this helps!

Sum of two numbers is -17. Their difference is 41. Find the numbers

wel

Answer:

$Suppose~the~two~numbers~are~x~and~y.\\From~the~first~condition,\\x+y=-17...........(1)\\From~the~second~condition,\\x-y=41.............(2)\\Adding~eq^n(1)~and~eq^n(2),~we~get,\\x+y+x-y=-17+41\\or, 2x = 24\\or, x=12\\Substituting~x=12~in~eq^n(2),\\y = -17-x = -17-12 = -29$
