The human eye blinks about [tex]\( 6.25 \times 10^6 \)[/tex] times each year, and a seal blinks about [tex]\( 1.01 \times 10^3 \)[/tex] times per year.
To find out how many times a human and a seal blink in one year, we simply take the given values for each. The question provides us with the number of times a human eye blinks in one year as [tex]\( 6.25 \times 10^6 \)[/tex]times. Similarly, it gives us the number of times a seal blinks in one year as [tex]\( 1.01 \times 10^3 \)[/tex] times.
Therefore, without the need for any additional calculations, we can state that in one year:
- A human blinks [tex]\( 6.25 \times 10^6 \)[/tex] times.
- A seal blinks [tex]\( 1.01 \times 10^3 \)[/tex] times.
These values are already given in the question and represent the total number of blinks for each species in a year. No further calculations are required to answer the question as it is asking for the number of blinks in one year, which is directly provided.
A ball is thrown from an initial height of 1 meter with an initial upward velocity of 13 m/s. The ball's height h (in meters) after t seconds is given by the following.
h=1+13t-5t^2
Find all values of t for which the ball's height is 8 meters.
Round your answer(s) to the nearest hundredth.
(If there is more than one answer, use the "or" button.)
For t=1.84 and t=0.76 the ball's height is 8 meters in equation h=1+13t-[tex]5t^{2}[/tex].
What is equation?An equation is a relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+ by=c. It is solved in order to find the values of variables.
How to solve equation?We have been given an equation h=1+13t-[tex]5t^{2}[/tex] and we have to find the values of t for which h=8.
So,
1+13t-[tex]5t^{2}[/tex]=8
[tex]-5t^{2}[/tex]+13t+1-8=0
[tex]-5t^{2}[/tex]+13t-7=0
Removing negative signs.
[tex]5t^{2}[/tex]-13t+7=0
We cannot solve through factorization so e use the following formula:
x=-b+-[tex]\sqrt{b^{2} -4ac}/2a[/tex]
t=(13+-[tex]\sqrt{-13^{2} -4*5*7}[/tex])/2*5
t=(13+-[tex]\sqrt{169-140}[/tex])/10
t=(13+5.38)/10, (13-5.38)/10
t=1.838, 0.762
By rounding off to nearest hundred t=1.84, 0.76.
Hence value of t for which h=8 meters are 1.84 and 0.76.

The population of a species of rabbit triples every year. This can be modeled by f(x) = 4(3)x and f(5) = 972. What does the 4 represent? (1 point) The starting population of the rabbits The population of the rabbits after five years The rate the population increases The number of years that have passed
Answer: The starting population of the rabbits
Step-by-step explanation:
Given: The population of a species of rabbit triples every year. This can be modeled by f(x) = 4(3)x and f(5) = 972.
We know that the exponential growth function is given by :-
[tex]f(x)=Ab^x[/tex], where A is the initial amount and b is the multiplicative rate of change in time x.
As compared to the given exponential function, we have
A=4
Therefore, 4 represents the starting population of the rabbits

A computer simulation tossed a 10-faced die 5 times. How many possible outcomes exist? 9,765,625 100,000 252 100
Answer:
Possible outcomes in tossing a 10-faced die 5 times is:
100,000
Step-by-step explanation:
A computer simulation tossed a 10-faced die 5 times.
Number of outcomes in each throw=10
Number of outcomes in 2 throws
=Number of outcomes in first throw×number of outcomes in second throw
=10×10
= 100
Hence, Number of outcomes in 5 throws
=10×10×10×10×10
=100,000
Possible outcomes in tossing a 10-faced die 5 times is:
100,000

Part A: Amir rented a scooter at $43 for 3 hours. If he rents the same scooter for 8 hours, he has to pay a total rent of $113.
Write an equation in the standard form to represent the total rent (y) that Amir has to pay for renting the scooter for x hours.
Part B: Write the equation obtained in Part A using function notation.
Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.
Answer:
Step-by-step explanation:
Part A: The two points that represent this situation are (3,43) and (8,113). To put this in standard form, I will first find the slope-intercept form. I did this in the image below.
Now, to find the standard form I will rearrange, 14x -y +1 = 0.
Part B: To put this in function notation I simply take my slope-intercept equation of y=14x+1, and replace y with f(x) so, f(x)=14x+1
Part C: To graph this, put the y, intercept at 1, and give the line a slope of 14/1. Label the x-axis with hours, from 0 - 8, and the y-axis with dollars, from 0-150.
P(A)=25,P(B|A)=920,P(A∩B)=?
We use the product rule in probability to find P(A∩B) = P(B|A) * P(A). Substituting given values, P(A∩B) = (9/20) * 25, which equals 11.25.
Explanation:The subject area of this question is probability, a topic within mathematics. Here, we are asked to find the intersection of Events A and B given the probabilities of A and the conditional probability of B given A. The rule of product in probability states that P(A∩B) = P(B|A) * P(A).
Let's calculate: P(B|A) is given as 9/20 while P(A) is 25. Thus,
P(A∩B) = P(B|A) * P(A) = (9/20) * 25 = 11.25

If a line contains the point (0, -1) and has a slope of 2, then which of the following points also lies on the line?
A. (2, 1)
B. (1, 1)
C. (0, 1)
The point that lie on the line is:
B. (1,1)
Step-by-step explanation:We are given that a line passes through the point (0,-1) and has a slope of 2.
We know that the equation of a line passing through (a,b) and having slope m is given by:
[tex]y-b=m(x-a)[/tex]
Here we have: (a,b)=(0,-1) and m=2
This means that the equation of line is:
[tex]y-(-1)=2(x-0)\\\\y+1=2x\\\\y=2x-1[/tex]
Now we will check which option is true.
A)
(2,1)
when x=2
we have:
[tex]y=2\times 2-1\\\\\\y=4-1\\\\\\y=3\neq 1[/tex]
Hence, option: A is incorrect.
B)
(1,1)
when x=1
we have:
[tex]y=2\times 1-1\\\\\\y=2-1\\\\\\y=1[/tex]
Hence, option: B is correct.
C)
(0,1)
when x=0
we have:
[tex]y=2\times 0-1\\\\\\y=0-1\\\\\\y=-1\neq 1[/tex]
Hence, option: C is incorrect.
