Choose the equation that represents an exponential function that passes through the point (2, 36).A. f(x) = 4(3)x
B. f(x) = 4(x)3
C. f(x) = 6(3)x
D. f(x) = 6(x)3

Answers

Answer 1
Answer: Since we were given only one point, we have to test each exponential function for the point (2,36).

Since exponential functions are of the form y=n(a)^(kx), The correct option is between option A and option C.

For option A,

f(x)=4(3)^(x)

On substitution, we have;

36=4(3)^(2)

\Rightarrow 36=4* 9

\Rightarrow 36=36.

Since the point satisfied the exponential function f(x)=4(3)^(x), the exponential function goes through it.

Hence the correct answer is option A.

No need to test for option C again.

 Which of the following best describes deflation as it relates to Earth science? A. Beach erosion caused by high tides
B. An avalanche caused by skiers
C. High tides caused by full moons
D. The lowering of land surface caused by wind

Answers

The lowering of land surface caused by wind best describes deflation as it relates to earth science. So for the given question, the right option will be option ā€œDā€. The word deflation can be used in a variety of ways. In case of finances, this is a commonly used term and is the opposite of inflation. In case using this word in relation to earth, it can be used to describe the erosion of loose materials by the force of wind from dry and flat areas like the deserts.



the answer is D.The lowering of land surface caused by wind
Deflation is wind activity which also causes rock erosion or transports sand and dirt.

Which of the following must unicellular organisms do to maintain homeostasis? A. Specialize cells to perform specific functions
B. Organize cells into tissues
C. Use chemical signals to communicate between its cells
D. Change food or sunlight into useful energy

Answers

The answer is C. Homeostasis is the process within a cell which aims at maintaining equilibrium within the cell. All living cells exhibit this process. Homeostasis happens by detecting and responding to slight changes in the normal processes inside the cell. Homeostasis occurs by regulating the movement of substances in and out of the cell to maintain a stable concentration inside the cell. It uses chemical signals to communicate between its cells.
