The axis which the point is reflected is vertical because for two different x-values, there is one y-value. In this case, you can tell that the vertical axis is x=0, which is basically the y-axis itself. To find the reflection point, find the average between the two x values. (3+(-3))/2 0/2 0 This value 0 is the x-value of the vertical axis.

11. The exponential function given by ​H(t)=80,030.83​(1.0481​)t​, where t is the number of years after 2010​, can be used to pr
telo118 [61]

A function assigns the value of each element of one set to the other specific element of another set. The number of centenarians in the country in 2013 is 9.4175×10⁴⁵.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The exponential function that can be used to project the number of centenarians in a certain country is H(t) = 80,030.83(1.0481)^t.

Now, the number of centenarians in the country in 2013 is,

H(t) = 80,030.83(1.0481)^t\\\\H(2013) = 80,030.83(1.0481)^{2013}\\\\H(2013) = 9.4175 \times 10^{45}

Also, the number of centenarians in the country in 2038 is,

H(t) = 80,030.83(1.0481)^t\\\\H(2038) = 80,030.83(1.0481)^{2038}\\\\H(2038) = 3.048 \times 10^{46}

Hence, the number of centenarians in the country in 2013 is 9.4175×10⁴⁵.

B and C are absurd; if a series converges, it must have a sum, but if a series diverges, it cannot have a sum.

Now, notice that

\dfrac12+\dfrac29+\dfrac4{27}+\dfrac8{81}+\cdots=\dfrac12+\dfrac{2^{2-1}}{3^2}+\dfrac{2^{3-1}}{3^3}+\dfrac{2^{4-1}}{3^4}+\cdots

That is, we can write the sum more compactly as

\dfrac12+\dfrac12\displaystyle\sum_{n=1}^\infty\left(\frac23\right)^n

The series is geometric with common ratio \dfrac23, so the series converges (and thereby has a sum), so the answer is D.

Janelle subtracts -4 from a number the result is 2 what is the number​
Gre4nikov [31]

Answer:

6

Step-by-step explanation:

So,

x - 4 = 2 (add 4 to both sides)

x - 4 + 4 = 2 + 4

x = 6
