Answer: Option D

Explanation:

x = input

y = f(x) = output

Table D shows the input x = 2 pair up with the output y = f(x) = 0. But this curve does not cross the x axis. So we can conclude that table D is an incorrect model to represent this curve.

In 2016, the population of the United States was approximately 3.24 x 10^8. It is expected that the population will be about 3.9

aleksandrvk [35]

Answer:

7.4 x 10^7

Step-by-step explanation:

3.98 x 10^8 - 3.24 x 10^8 = 0.74 x 10^8 (not scientific notation, because it isn't full number)

0.74 x 10^8 ---> 7.4 x 10^7

- got seven by counting the spaces it moved over (right decrease, while left increases)

Solve 7.8e^((x/3)ln(5))=14. What are the exact and approximate solutions?

Dimas [21]

$\bold{\text{Answer}:\quad x=3\bigg(\dfrac{ln\frac{14}{7.8}}{ln(5)}\bigg)=1.09}$

Step-by-step explanation:

$7.8e^{\frac{x}{3}\cdot ln(5)}=14\\\\\\e^{\frac{x}{3}\cdot ln(5)}=\dfrac{14}{7.8}\\\\\\ln\bigg(e^{\frac{x}{3}\cdot ln(5)}\bigg)=ln\bigg(\dfrac{14}{7.8}\bigg)\\\\\\\frac{x}{3}}\cdot ln(5)=ln\bigg(\dfrac{14}{7.8}\bigg)\\\\\\\large\boxed{x=3\bigg(\dfrac{ln\frac{14}{7.8}}{ln(5)}\bigg)}\\$

x ≈ 1.09

A. 34cm^3 b. 1560cm^3 c. 104cm^3 d 676cm^3

Vanyuwa [196]

Answer:

676 cubic cm choice d

Step-by-step explanation:

Base area times height gets volume

Base area = (1/2)*13 * 8 = 52 sq. cm (area of the right triangle)

height = 13 cm here

Volume = 13 cm * 52 sq. cm = 676 cubic cm
