The answer to your question is distance = 3500000 km

Step-by-step explanation:

Data

Scale 1 : 500000

7 cm

Process

1.- To solve this problem use direct proportions or rule of three.

1 : 500 000 :: 7 : x

2.- Multiply the middle numbers and the result divide it by the edge.

x = (7 x 500000) / 1

Simplification

x = 3500000 km

Please help to solve this.<br> Find sin5x,if sinx+cosx=1,4

MrMuchimi

Answer:

Hello,

Step-by-step explanation:

we must first remember that:

$\boxed{sin(5x)=5sin(x)-20*sin^3(x)+16*sin^5(x)}\\\\$

Let say t=sin(x)

$sin(x)+cos(x)=1.4\\\\t+\sqrt{1-t^2}=1.4\\\sqrt{1-t^2}=1.4-t\ we\ square\\1-t^2=1.4^2+t^2-2.8*t\\2t^2-2.8*t+0.96=0\\\Delta=2.8^2-4*2*0.96=0.16=0.4^2\\\\t=\dfrac{2.8-0.4}{4} =0.6\ or\ t=\dfrac{2.8+0.4}{4}=0.8\\\\t^3=0,216\ or\ t^3=0,512\\\\t^5=0,07776\ or\ t^5=0,32768\\\\\boxed{sin(5x)=5*0.6-20*0.216+16*0.07776=-0,07584}\\\\or\\\\\boxed{sin(5x)=5*0.8-20*0.512+16*0.32768=-0,99712}$

an investment is expected to pay 5 per year compounded continuously. If you want the value of the investment to be $700,000 afte

andre [41]

The multiplier for continuous compounding is e^(rt). You want
700,000 = P·e^(0.05·25) ≈ 3.490343P
Then
700,000/3.490343 = P

You should invest $200,553 initially.
