Sylvia puts in $121.

10% of (multiply) $210.
210= 100 each person plus an additional ten from Leroi
so .10*210 = $21. 
Add Sylvia's $100 plus $21 and viola, $121

Answer:

I think the way they are telling is that the triangle will move to the third quadrant,

If so, then the coordinates of P'Q'R' will just be the negative of PQR.

3.0450 x 10^4 as an ordinary number
kifflom [539]

Answer:

30450 is the answer.

Step-by-step explanation:

Given number is 3.0450 \times 10^4.

We need to write it as an ordinate number.

It is 3.0450 times 10 to the power 4.

It would mean that,

3.0450 \times 10^4=3.0450 \times 10000\\\\=\dfrac{3.0450 }{10000}\times 10000\\\\=30450

Hence, the required answer is 30450.

The exponential model A=429e 0.024t describes the​ population, A, of a country in​ millions, t years after 2003. Use the model t
d1i1m1o1n [39]

Answer:

Year 2,590

Step-by-step explanation:

In this question, we are asked to calculate the year at which the population of a country will be a certain amount given the exponential equation through which the equation proceeds.

Let’s rewrite the exponential function;

A = 429e^0.024t

Now here, our A is 559,000,000

t is unknown

Let’s substitute this value of A in the exponential equation;

559,000,000 = 429 * e^0.024t

559,000,000/429 = e^0.024t

1,303,030.303030303 = e^0.024t

Let’s take the logarithm of both sides to base e, we have;

ln(1,303,030.303030303) = ln(e^0.024t)

14.08 = 0.024t

t = 14.08/0.024

t = 587 years

Now, we add this to year 2003 and this gives year 2590
