Speed is the ratio of distance and time
The elapsed time is 3 secondsThe average speed is 1.33 meters per secondHow to calculate the elapsed timeThe elapsed time is the difference between the final time and the initial time.
So, we have:
Time elapsed = 4.5 seconds - 1.5 seconds
Evaluate the difference
Time elapsed = 3 seconds
Hence, the elapsed time is 3 s
How to calculate the average speedThe average speed is the quotient of the distance and the elapsed time.
So, we have:
Average speed = 4 meters/ 3 seconds
Evaluate the quotient
Average speed = 1.33 meters per second
Hence, the average speed is 1.33 m/s

Measuring by using Trigonometry
Answer:
x approximately = 11.971, y approximately = 0.837
Step-by-step explanation:
the 12 ft is the hypotenuse of the right angle triangle formed
Cos (theta) = adjacent/hypotenuse
so Cos(4) = x/12, solving for x = 11.971
Sin(theta) = opposite/hypotenuse
so Sin(4) = y/12, solving for y = 0.837
The seller wants to take $185,000 on the sale of his house after paying the commission of 6%. How much must the selling price be?
Answer:
196808.5106
Step-by-step explanation:
the seller will take 94% from the selling price and pay 6% to the commission, and he wants to take 185000 dollars
let the price = x
then x * 94% = 185000
Solving for x you get the answer
Write 3-5 sentences about why you should receive brainliest. Best answer gets brainliest. ::)
Answer:
First off, I LOVE helping people even if I'm not a professor teacher, or tutor. However, I always do my best to answer the questions as close to perfection as possible even if it can take an hour. I want people to easier to understand and leaner better when I gave an answer to their question, by doing that, I felt very proud of myself and felt like I accomplished a goal. I'm still very young and just started using Brainly, so I don't really know what a brainlist is (DON'T LAUGH). Even so, if you don't think that I deserve the brainlist, it's fine because once I'm older and have more experience, I could help more and more people with their questions or problems. If you actually gave me a brainlist, I'll be really grateful and I might give you a brainlist if you answered my questions. Anyway, when I received a brainnlist, the first thing that came up in my mind is that my answers are actually useful for once. P.s. if you give a brainlist, Thank u

What is the factored form of the polynomial? x2 − 15x 36 (x − 4)(x − 9) (x − 3)(x − 12) (x 4)(x 9) (x 3)(x 12).
Polynomials consist of both indeterminates and coefficients. The factors of the polynomial x² - 15x + 36 is (x-3)(x-12).
What are polynomials?A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.
Given to us
x² - 15x + 36
To find the factors of the polynomial,
[tex]x^2 - 15x + 36 \\\\[/tex]
We will replace -15 with two numbers such that their sum is -15 while, their product must be 36.
[tex]x^2 - 15x + 36 \\\\ = x^2 -12x-3x +36\\\\[/tex]
now, we will take x as the common term from the first two-term, while 3 as the common term from the next two terms.
[tex]= x^2 -12x-3x +36\\\\= x(x-12) - 3 (x - 12)\\\\= (x-3)(x-12)[/tex]
Hence, the factors of the polynomial x² - 15x + 36 is (x-3)(x-12).

Need answer fast please. Which line is perpendicular to y = x + 2 and passes through (4,-1)?
y = -x+1
y = -x + 3
y = -x + 2
y = -x +4
Answer:
C. y = -x + 3
Step-by-step explanation:
y = x + 2
Find perpendicular slope (opposite reciprocal):
x/1 --> -1/x or -x
Convert to point-slope form:
y - (-1) = -1 (x - 4)
y + 1 = -1x + 4
y = -x + 3
you install 618 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 152 feet. What is the length of the yard?
Answer:
The length of the yard is 157 feet
Step-by-step explanation:
P= L+L+W+W or 2L+2W. (P is perimeter, L is length, and W is width.)
Substitute in known values for the variables.
618=2L+2(152)
Multiply.
618=2L+304
Now solve for L by doing inverse operations (subtract).
314=2L
Divide.
L=157
So the yard is 157 feet long.

ERROR ANALYSIS Describe and correct the error in
graphing and comparing
y= x^2and y = 0.5x^2.
Answer:
The graph should be stretched rather than become narrower.
Step-by-step explanation:
To figure this out, just create some example points.
At x = 0, your y-value will always be 0. But if you were to plug in the value 1, you would get a y-value of 1 in y=x^2, but a value of 0.5 in y=0.5x^2. If you were to plug in a value of 2, you would get a value of 4 in y=x^2, but a value of 2 in y=0.5x^2.
If you continue this pattern for a few more points, then plot them, you will see that adding a coefficient of 0.5 simply stretches the graph
