3. A student measures the time it takes for a sheet of paper to fall to the ground from a marked height. The student then crumples the same piece of paper and drops the paper from the same. What variable did the student change? ​

Answer:

answer in explination

Step-by-step explanation:

A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.

I dont really know what the question is so i just put what "Value of the constant" is

Answer:

1.6

Step-by-step explanation:

Step one:

given data

x1=10

y1=16

x2=30

y2=48

Required

The slope of the given points

Step two:

The expression for the slope is

S= change in y/change in x

S= y2-y1/x2-x1

S= 48-16/30-10

S=32/20

S=1.6

Hence the slope is 1.6

Answer:

5.3

Step-by-step explanation:

It will take a time 0f 5.5 hours to pick 40 bushels of apple if they worked together.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

Given that,

Amount of bushels picked by Maria in 10 hours = 40

Amount of bushels picked by Maria in 1 hour = 40/10 = 4

Amount of bushels picked by Kayla in 12 hours = 40

Amount of bushels picked by Maria in 1 hour = 40/12 = 3.333

Amount of apple picked by both Maria and Kayla in 1 hour if they worked together = 4 + 3.333 = 7.333

Let x be the time taken to pick 40 bushels of apple by both.

Using proportional concept,

x / 40 = 1 / 7.333

x = 40 / 7.333

x = 5.4548 ≈ 5.5 hours

Time taken if they both worked together is 5.5 hours.

Answer:

y=-3x-5

Step-by-step explanation:

given equation:

3y=x-4

slope intercept form is y=mx+b

(m is the slope, b is the y intercept)

divide by 3

y=1/3x-4/3

perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.

so to find the slope of the perpendicular line, use this equation:

1/3m=-1

multiply by 3

m=-3

the slope of the new line is -3.

here is our equation so far:

y=-3x+b

now, we need to find b.

Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b

1=-3(-2)+b

multiply

1=6+b

subtract 6

-5=b

so the line is y=-3x-5

Hope this helps!

Answer:[tex]-\frac{189}{208}[/tex]

Step-by-step explanation:

Given

[tex]\sin x=\frac{8}{10}[/tex]

x lies in the second quadrant where sin and cosec is positive and rest trigonometric functions are negative

so, [tex]\cos x=-\sqrt{1-sin ^2 x}\\\cos x=-\sqrt{1-(\frac{8}{10})^2}=-\sqrt{\frac{36}{100}}\\\cos x=-\sqrt{\frac{6}{10}}[/tex]

[tex]\tan x=\frac{\sin x}{\cos x}=-\frac{4}{3}[/tex]

similarly, [tex]\tan y=-\frac{12}{5}[/tex]

Also, y lies in 4 th Quadrant where cos and sec is positive and rest trigonometric functions are negative

[tex]\sec y=\sqrt{1+\tan ^2y}=\sqrt{1+(-\frac{12}{5})^2}\\\sec y=\frac{13}{5}\\\cos y=\frac{5}{13}\\\sin y =\frac{\tan y}{\cos y}=-\frac{12}{13}[/tex]

Now putting the values

=[tex]\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{(\frac{-6}{10})(\frac{5}{13})+(\frac{8}{10})(\frac{-12}{13})}{(\frac{-8}{6})-(\frac{-12}{5})}\\\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{\frac{-126}{130}}{\frac{16}{15}}=-\frac{189}{208}[/tex]

Answer:

4/7

Step-by-step explanation:

The amount of cup of chocolate each person get is 4/7.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Number of person = 7

Number of cups of chocolate = 4

The equal amount of hot chocolate each person gets.

= 4/7

Thus,

4/7 cup of hot chocolate each person got.

Yes, the binomial is a factor of the polynomial function.

Step-by-step explanation:

Consider the given polynomial.

Factor out the common term [tex]x^2[/tex] from the first two terms and [tex]-25[/tex] from the last two terms.

[tex]x^3 + 3x^2 -25x-75=x^2(x+3)-25(x+3)[/tex]

Factor out the polynomial.

[tex]x^2(x+3)-25(x+3)=(x+3)(x^2-25)[/tex]

Further, simplify.

[tex](x+3)(x^2-25)=(x+3)(x+5)(x-5)[/tex]

Therefore, [tex]x^3 + 3x^2 -25x-75=(x+3)(x+5)(x-5)[/tex]

A binomial factor is simply a factor with two terms, like (x - a).

Hence, the given polynomial function is binomial as it contains the factor with two terms, like (x - a).
