Answer:

8,250,000,000.

Step-by-step explanation:

10 % is equivalent to 0.10.

That is 7,500,000,000 + 0.10 * 7,500,000,000

= 7,500,000,000 + 750,000,000

= 8,250,000,000.

Answer:

8,250,000,000

Step-by-step explanation:

The current population is 7500 000 000

then, let's get 10% 0f 7500 000 000

which is 10/100×7500000000

0.1×7500000000= 750,000,000

therefore, in the next 10years the population will be

750,000,000+7500,000,000

in 2028 the population will be 8,250,000,000

$\bf |x^2+3x-1|\ \textless \ 3\implies 
\begin{cases}

-(x^2+3x-1)\ \textless \ 3
\end{cases}\\\\

x^2+3x-1\ \textless \ 3\implies x^2+3x-4\ \textless \ 0\implies (x+4)(x-1)\ \textless \ 0

Find the first term of the following geometric sequence ----,42,126,378,1,134

sergey [27]

Since it is a geometric sequence each term will be a specific multiple of the term preceding it, called the common ratio...

126/42=378/126=1134/378=3

The sequence is a(n)=a(3)^(n-1) and we know the second term is 42 so:

42=a(3)^(2-1)

42=3a

a=14

So the first term is 14.
