To determine when the coin will be worth $150, you can substitute 150 for y and solve for t. What value do you get for t when you do that?
Answer:
5.23 years, the time at which the coin has increased in value to $150.
Step-by-step explanation:
Use the exponential function f(t) = 4*2^t.
Substitute $150 for f(t): $150 = 4*2^t.
Simplify this by dividing both sides by 4: $150/4 = 2^t, or $37.50 = 2^t.
Next, solve for the value of t. To do this, take the common log of both sides, obtaining:
log 37.50 = t*log 2. Thus, t = [log 37.50] / [log 2]. Evaluate this using a calculator:
t = 1.57403 / 0.30103 = 5.23 time units. For example, this could be 5.23 years.
Answer:
It will take about 17.7 years, or almost 18 years, for the coin to be worth $150.
Because the initial year was 2016, the coin is predicted to be worth $150 in 2034.

Dr. Jimenez found that after applying an antibiotic to bacteria, he observed only 90% of the bacteria left in the culture dish each hour. If the initial bacteria count was 100, what was the bacteria count after 5 hours? Round to the nearest whole number.
There were ___ bacteria after 5 hours.
The complete statement is:
There were 59 bacteria after 5 hours
The initial population of the bacteria is given as:
[tex]a =100[/tex]
The proportion left after each hour is given as:
[tex]b = 90\%[/tex]
An exponential function is represented as:
[tex]f(x) = ab^x[/tex]
Substitute values for (a) and (b)
[tex]f(x) = 100 \times (90\%)^x[/tex]
Express percentage as decimal
[tex]f(x) = 100 \times (0.9)^x[/tex]
After 5 hours, the value of x is 5
i.e. x = 5
So, we have:
[tex]f(x) = 100 \times (0.9)^5[/tex]
Evaluate the exponent
[tex]f(x) = 100 \times 0.59049[/tex]
Multiply
[tex]f(x) = 59.049[/tex]
Approximate
[tex]f(x) = 59[/tex]
Hence, there were 59 bacteria after 5 hours

Paulo took out a $900 loan using an 12% simple interest rate for a period of 9 months. What the effective annual interest rate for the loan? Give your answer as a percentage to the nearest tenth of a percent.
Answer:
12.68%
Step-by-step explanation:
To calculate effective annual interest rate we need to use the following formula:
[tex]i=(1+\frac{r}{m})^m-1[/tex]
Where, 'i' is the effective annual interest rate
'r' is the annual rate of interest
'm' is the frequency of compounding.
When there is continuous compounding the effective annual rate uses the following formula:
[tex]i=e^r-1[/tex]
In our case we would are assume that there is continuous compounding since no information regarding the frequency of compounding is given:
Plugging r=12%=0.12, we get:
[tex]i=e^{0.12}-1[/tex]
[tex]i=1.1274-1=0.1274[/tex]
[tex]i=0.1274[/tex]
[tex]i=12.74\%[/tex]
Therefore, the effective annual interest rate is 12.74%.

The graph represents a person’s heart rate in beats per minute during 30 minutes of exercise. Which statement best describes the relationship between heart rate and time during exercise? The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually increases for 5 minutes. The heart rate decreases for 6 minutes, remains constant for 19 minutes, and then gradually increases for 5 minutes. The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually decreases for 5 minutes. The heart rate remains constant for 6 minutes, increases for 19 minutes, and then gradually decreases for 5 minutes.
We know that
when we start exercise our hear beats starts increasing gradually
because blood flowing rate becomes higher
and it keeps increasing upto a certain limit
because for normal human beings maximum heart rate is 135 beats per minute
and it remains constant there for few minutes
and as we slow down slowly
It will start decreasing gradually and then becomes normal
we can see the graph
so,
The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually decreases for 5 minutes..........Answer
Answer:The heart rate increases for 6 minutes, remains constant for 19 minutes, and then gradually decreases for 5 minutes. Positive
Step-by-step explanation:
A mouse scurries across your kitchen floor at 2.0 feet per second. How many miles can the mouse travel in 1.5 hours (rounded to the nearest tenth)?
Answer: The mouse can travel 2.045 miles .
Step-by-step explanation:
Speed of mouse = 2.0 feet per second.
Time traveled by mouse = 1.5 hours = 1.5 × 3600 seconds [ as 1 hour = 3600 seconds]
Distance traveled by mouse in 1.5 hours = speed × time
= 2.0 × 1.5 × 3600 = 10800 feet.
We know that
1 mile = 5280 feet
then 1 foot = 1/5280 miles
Distance in miles = [tex]10800\times \frac{1}{5280} miles=2.045miles[/tex]
Given
A mouse scurries across your kitchen floor at 2.0 feet per second.
Find out the mouse travel in 1.5 hours.
To proof
FORMULA
Distance = speed × time
[tex]1foot = \frac{1}{5280} miles[/tex]
Convert feet per second into miles per second
[tex]= \frac{2.0}{5280}[/tex]
As given in the question
Time = 1.5 hours
1 hours = 3600 second
Time convert in the second
Time = 1.5 × 3600 second
= 5400 second
put all these value in the above formula
we get
[tex]Distance= \frac{2.0\times 1.5 \times 3600}{5280}[/tex]
[tex]Distance= \frac{10800}{5280}[/tex]
= 2.04 (approx) miles
= 2.0 miles
Hence proved

How do you work this problem? 5 - 2x = 0
Answer:
x = 5/2

Isolate x by adding 2x to both sides, obtaining: 5 - 2x + 2x = 2x. Then 5 = 2x, and dividing both sides by 2 results in x = 5/2.
What is the next term in the pattern shown below? 4.5, 9, 13.5, 18
22.5
note that the difference (d ) between each term is
d = 9 - 4.5 = 13.5 - 9 = 18 - 13.5 = 4.5
to obtain the next term add 4.5
next term = 18 + 4.5 = 22.5
The next term in the pattern is 22.5.
To find the next term in the pattern, it's essential to identify the underlying rule or mathematical operation that governs the progression of the given numbers.
In this case, we can observe that the sequence is increasing by a consistent difference of 4.5 between each consecutive term.
Starting from 4.5 and adding 4.5 successively, we get:
4.5 + 4.5 = 9
9 + 4.5 = 13.5
13.5 + 4.5 = 18
The next term would be:
18 + 4.5 = 22.5
So, the next term in the pattern is 22.5.
In this sequence, each term is obtained by adding 4.5 to the previous term, resulting in an arithmetic progression.
If you continue this pattern, you will keep adding 4.5 to each subsequent term to find the following numbers in the sequence.

Four times a number increased by six is the same as seven times the number.
Call that number x.
Then rewrite as equation:
4x+6=7x
solve for x
6=3x
2=x
So the number is 2.
Check that 2 is the number by following the original wording, mentally.
Hey there!!
Let's take the number as 'x'
4 times the number is 4x
This is increased by 6
We will have to add 6.
... 4x + 6
7 times a number is 7x
... 7x
Both these values are equal.
Hence,
... 4x + 6 = 7x
... 6 = 3x
... x = 2
Hence, the number is 2.

Which graph represents the function?
Answer: Upper right corner
=========================================================
How I got that answer:
The line y = x goes through (0,0) and (1,1). You would normally extend this line out as far as you can in both directions. However, the inequality x < -1 says you can only graph this if x is less than -1. We will not graph any part of the graph that is beyond x = -1 to the right. So we only have a small piece of it. The left piece of y = x. There is an open hole at the endpoint.
Similarly, y = -x is only graphed if x >= -1. We have a closed endpoint here. This graph goes through (0,0) and (1,-1). We erase the portion that is to the left of x = -1.
Doing all this leads to the upper right corner choice as our answer. The bottom right corner is close to the answer, but the open and closed endpoints are in the wrong spots.

A group of hikers walks 2 miles east and then 1 mile north. After taking a break, they then hike 4 miles east to their final destination. What vector describes their hike from their starting position to their final destination? Let 1 unit represent 1 mile.
Answer:
Intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction
Step-by-step explanation:
Required vector is consists of the two components
vx= 2+4=6 units and vy= 1 unit and vx ⊥ vy
We will use Pythagorian theorem to find intensity of the vector v
v∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 units
The angle ∡α between vector and east direction we wil find with tanα
tanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
Good luck!!!
Answer:
The vector that describes their hike from their starting position to their final destination is < 6, 1 >
