Simple interest,
FV=P(1+ni)
FV=future value=2500
P=present value, invested amount
n=number of years, =3
i=annual interest rate, =0.095
2500=P(1+3(0.095))
Solve for P.

Use properties to find the sum or product.1. 6 X 892. 93 +(68 +7)3. 5 X 23 X 24. 8 X 51 5. 34 + 0 + 18+ 26 6. 6 X 107
Cloud [144]

3. We want to solve using properties;

\begin{gathered} 5\times23\times2 \\ =5\times2\times23 \\ =5\times2\times(20+3) \\ =10\times(20+3) \\ =(10\times20)+(10\times3) \\ =200+30 \\ =230 \end{gathered}

It simply involve trying to reduce numbers to their simpliest form to make multiplication and addition easy without using calculator.

like; 21=20+1, 39=40-1 etc.

4. Given;

\begin{gathered} 8\times51 \\ =8\times(50+1) \\ =8\times50+8\times1 \\ =400+8 \\ =408 \end{gathered}

(Newton's law of cooling/warming) Use 'separation of variables' to solve the IVP: 3+2-5 pts = k(90- T), k>0 with IC: T(0) 0.
IrinaVladis [17]

Step-by-step explanation:

The Newton's law differential equation is:

\frac{dT(t)}{dt} = k(90-T(t))

We solve by variable separation

\frac{dT(t)}{(90-T(t))} = kdt

integrating both sides between time 0 to time t, T(0) = 0 to T(t).

\int\limits^T_0 {\frac{dT}{90-T} } \ = \int\limits^t_0 {k} \, dt

-(ln(90-T)-ln(90-0)) = kt-k*0

applying logarithm properties

-ln(\frac{90-T}{90}) = kt (*)

applying exponential function to both sides

(\frac{90-T}{90}) = e^{-kt}

T= 90-90e^{-kt}

Now replacing the condition T(1) = 45 in (*)

-(ln(\frac{90-45}{90}) = k*1

k = 0.6931
