<span>D. The number will be less than 1 because when adding the exponents, 
11 + (-14) = 3, and a number in scientific notation with a negative exponent is less than 1.

</span>(4.296 * 10^{11}) * (1.8614 * 10^{-14})= \\ \\ 4.296*1.8614*10^{11+(-14)}=\\\\7.99657*10^{-3}= \\  \\  \cfrac{7.99657}{1000}=\\\\0.00799657<span>

Write a function in terms of t that represents the situation.
yuradex [85]

Given that opulation of 100,000 decreases by 2% each year.

Now question says to write a function in terms of t that represents the situation.

Question is talking about population decrease so we can apply decay formula. which is given by:

P(t)=P_0(1-r)^t

Where A is the population at any time t.

P_0 is the initial population so P_0=100000

r is the rate of decrease so r=2%=0.02

t is the number of years

Now plug those values, we get:

P(t)=100000(1-0.02)^t

P(t)=100000(0.98)^t

Hence required function is P(t)=100000(0.98)^t.

Principal=₹42800

Rate of interest=5% but 2 years so multiply by 2 =5×2=10%

Time=2 years

Simple interest=42800×10×2/100= ₹8560

Amount=42800+8560=Rs51360

The answer is ₹ 51360

Find the next two numbers in the pattern.
RSB [31]
Let u_n be the n' th term of the sequence.


u_1=7\\\\u_2=-28=-7\cdot4\\\\u_3=112=7 \cdot4^2\\\\u_4=-448=-7\cdot 64=-7\cdot 4^3\\\\u_5=1792=7 \cdot 4^4

thus it is clear that:

u_6=-7 \cdot 4^5=7168\\\\u_7=7\cdot 4^6=28,672
