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:
Answer:
1). Option (A)
2). Option (A)
Step-by-step explanation:
1). A worker bee has the mass = 0.00011 kg
In scientific notation we can convert the mass of bee as,
0.00011 =
=
Since 1.1 ≈ 1,
Therefore, 1.1 × 10⁻⁴ ≈ 1 × 10⁻⁴ kg
Option (A) is the answer.
2). An African elephant has a mass = 8139 kg
In scientific notation,
8139 = 8.139 × 10³
Since, 8.139 ≈ 8
Therefore, 8139 kg = 8.139 × 10³ kg
Option (A) is the answer.

A rectangle measures 7.08 cm by 3.2 cm.
Work out the area of the rectangle.
Answer:
22.67 cm^2
Step-by-step explanation:
The computation of the area of the rectangle is shown below:
As we know that
Area of the rectangle = Length × breadth
Here we assume the length be 7.08 cm
Or breadth be 3.2 cm
Or if we assume them inverse like length be 7.08 cm and breadth be 3.2 cm
SO the area of the rectangle is
= 7.08 cm × 3.2 cm
= 22.67 cm^2
In the both cases the answer would be the same
[Calculus] analyze speed from position. Show steps, please!
Answer:
B
Step-by-step explanation:
We are given that the position of a particle is modeled by the function:
[tex]s(t)=2t^3-24t^2+90t+7[/tex]
And we want to find the times for which the speed of our particle is increasing.
In other words, we want to find the times for which our acceleration is positive (a(t)>0).
So first, we will find our acceleration function. We can differentiate twice.
By taking the derivative of both sides with respect to t, we acquire:
[tex]\displaystyle s^\prime(t)=v(t)=\frac{d}{dt}\big[2t^3-24t^2+90t+7\big][/tex]
Differentiate:
[tex]v(t)=6t^2-48t+90[/tex]
This is our velocity function. We can differentiate once more to acquire the acceleration function. Therefore:
[tex]\displaystyle v^\prime(t)=a(t)=\frac{d}{dt}\big[6t^2-48t+90\big][/tex]
Differentiate:
[tex]a(t)=12t-48[/tex]
If our speed is increasing, our acceleration must be positive. So:
[tex]a(t)>0[/tex]
By substitution:
[tex]12t-48>0[/tex]
Now, we can solve for t:
[tex]12t>48\Rightarrow t>4[/tex]
Therefore, the only interval for which the speed of the particle is increasing (i.e. the acceleration is positive) is for all times t>4.
So, our answer is B.

“Which of the following is most likely caused by chemical weathering” A.cirques carved out by a melting glacier
B. U-shaped valleys formed in a mountain region
C. Rocks and sediment transported and deposited
D.unrecognizable facial features on a marble statue
Answer:
D. Unrecognizable facial features on a marble statue
Step-by-step explanation:
The first 3 answer choices are all examples of physical weathering, not chemical weathering.
This is because the changes were caused by natural things such as flowing water and heating.
However, unrecognizable facial features on a marble statue would be caused by chemical weathering, where chemicals can erode marble and cause distortion in a statue.
So, D is the correct answer.

The response to a question has three alternatives: A, B, and C. A sample of 120 responses provides 60 A, 12 B, and 48 C. Show the frequency and relative frequency distributions.
Answer:
CLASS FREQUENCIES RELATIVE FREQUENCIES
A 60 0.5
B 12 0.1
C 48 0.4
TOTAL 120 1
Step-by-step explanation:
Given that;
the frequencies of there alternatives are;
Frequency A = 60
Frequency B = 12
Frequency C = 48
Total = 60 + 12 + 48 = 120
Now to determine our relative frequency, we divide each frequency by the total sum of the given frequencies;
Relative Frequency A = Frequency A / total = 60 / 120 = 0.5
Relative Frequency B = Frequency B / total = 12 / 120 = 0.1
Relative Frequency C = Frequency C / total = 48 / 120 = 0.4
therefore;
CLASS FREQUENCIES RELATIVE FREQUENCIES
A 60 0.5
B 12 0.1
C 48 0.4
TOTAL 120 1
How is the circumference of a circle related to its diameter
Given the diagram below, solve for the value of x.
==========================================================
Explanation:
Sides ED and FD are the same length due to the red tickmarks.
The angles opposite these side lengths, angle E and angle F, are congruent as well. So angle F is also x.
For any triangle, the three angles always add to 180
F+E+D = 180
x+x+74 = 180
2x+74 = 180
2x+74-74 = 180-74 .... subtract 74 from both sides
2x = 106
2x/2 = 106/2 ... divide both sides by 2
x = 53
As a check,
F+E+D = x+x+74 = 53+53+74 = 180
which verifies the answer.
A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per message received. Using s to represent the number of text messages sent in one month and r to represent the number of text messages received in one month, the following equation can be used to calculate the total monthly cost, c.
C=39.95+.15(s+r)
If it is known that the total monthly cost is $53.45 and 63 text messages were received, solve for s, the total number of text messages sent.
Answer:
The total number of text messages sent was 27.
Step-by-step explanation:
The monthly cost of the cell phone plan, in function of the number of text messages sent(s) and the number of messages received(r), is given by:
[tex]C = 39.95 + 0.15(s + r)[/tex]
In this question, we have that:
[tex]C = 53.45, r = 63[/tex]
We put this into the equation to find the value of s. So
[tex]C = 39.95 + 0.15(s + r)[/tex]
[tex]53.45 = 39.95 + 0.15(s + 63)[/tex]
[tex]0.15s + 9.45 = 13.50[/tex]
[tex]s = \frac{13.50 - 9.45}{0.15}[/tex]
[tex]s = 27[/tex]
The total number of text messages sent was 27.
