Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What multiplicative rate of change should Hal use in his function?

Answers

Answer
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98
                                                                                                                   =9.8×10⁻¹

Explanation
The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.
In this case the first term = 10000
The second term = 98% × 10000 = 9800.
The common ratio = 9800/10000=49/50
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.
The equation of the exponential rate would be;
10,000ₓ0.98ⁿ.
where n is the number years.

Answer: B

Step-by-step explanation:

0.98

Which of the following is the function representing the graph below? graph begins in the third quadrant near the line y equals negative 3 and increases slowly while crossing the ordered pair 0, negative 2. When the graph enters the first quadrant, it begins to increase quickly throughout the graph.f(x) = 4x
f(x) = 4x − 3
f(x) = 4x + 3
f(x) = 4(x + 3)

Answers

Answer:

  f(x) = 4^x -3

Step-by-step explanation:

All of the listed functions are linear functions with a constant slope of 4. None of them goes through the point (0, -2).

__

So, we assume that there is a missing exponentiation operator, and that these are supposed to be exponential functions. If the horizontal asymptote is -3, then there is only one answer choice that makes any sense:

  f(x) = 4^x -3

_____

The minimum value of 4^z for any z will be near zero. In order to make it be near -3, 3 must be subtracted from the exponential term.

A plane takes off at an angle of elevation of 15° and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?

Answers

The angle of elevation is 15 degrees. This angle is measured from the horizontal. This problem requires us to review our triangle relationships. This triangle is a right triangle. That means to answer this problem we have to noe the relationship sin(angle) = opposite/hypotenuse. The 3000 is the hypotenuse measurement and we are to find the opposite. 3000sin(15) = 776.45m.

Factorise x² + 4x + 3.I understand everything perfectly until I have to split the two sections, add up and pull out the common factors: x² + 3x: common factor is x 1x + 3: common factor is 1 From here I do not understand how you get to the answer which I do know is (x + 1) • (x + 3). None of the explanations out there give detail to this step. I don’t understand how adding those two groups up (while pulling out common factors) will give you (x + 1) • (x + 3)! I would hugely appreciate any help on this! Thank you :)
