Step-by-step explanation:

if I understand your typing correctly, and there is nothing missing, we have

f(x) = 0.6x⁵ - 2x⁴ + 8x

the "end behavior" means the general tendency of the result values for very large or very low values of x (going to +infinity and -infinity).

the higher (or lower in the negative direction) x gets, the more the highest exponent will dominate the result values.

it does not matter, that it has a diminishing factor (or coefficient) like 0.6.

the much stronger progression of x⁵ vs. smaller exponents like x⁴ or x will easily compensate for that with sufficiently large x.

so, ultimately, the term with the highest exponent (in our case 0.6x⁵) defines the end behavior.

with x going to +infinity, so does the function result (+infinity).

with x going to -infinity, so does the function result (-infinity, because an odd exponent number like 5 will maintain the sign of the argument).

Answer:

Each gets 14 cards.

Step-by-step explanation:

7*8=56

56/4 equals 14

We divide 56 by 4 since 4 is the total number of friends.

The resulting equation after the first step in the solution is: 2v + 4 = 8.

In Mathematics, an equation is sometimes referred to as an expression and it can be defined as a mathematical expression which shows that two (2) or more thing are equal.

In this exercise, you're required to describe the steps that should be taken to find a solution to the given equation by solving for v. Therefore, the appropriate and required steps that should be used include the following:

Step 1: Rearrange the equation by collecting like terms.

(v + v) + 4 = 8

Step 2: Add the like terms together.

2v + 4 = 8

Step 3: Subtract 4 from both sides of the equation.

2v + 4 - 4 = 8 - 4

2v = 4

Step 4: Divide both sides of the equation by 2.

v = 4/2

Benchmark percentage of 1% = 9.6 & 10% = 24.

What is Free Throw Percentage?

Free throw percentage (FT%) puts a player’s successful free throws in perspective to their total attempts.

In basketball, a free throw (or foul shot) is awarded to a player who has been fouled by the other team. The number of free throws depends on where on the court the player was while being fouled.

To find 1% of a number, we can move the decimal point of the number two places to the left.

Therefore, 1% of 120 is 1.2

To find 10% of a number, we can move the decimal point of the number one place to the left.

Therefore, 10% of 120 is 12

Since 10% of 120 is 12 and

20% = 2 x 10%

then 20% of 120 = 2 x 10% of 120

= 2 x 12 = 24

Since 1% of 120 is 1.2 and

8% = 8 x 1%

then 8% of 120 = 8 x 1%  of 120

= 8 x 1.2 = 9.6

Hence the answer is, Benchmark percentage of 1% = 9.6 & 10% = 24.

The trigonometric measures for the given angle are as follows:

We are given the measure of the sine for the angle and we need to find the three measures, sine, cosine and tangent for half the angle.

These measures are dependent on the cosine of the function, hence we apply the definition of the tangent as follows:

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

Hence:

[tex]\sqrt{2} = \frac{\sin{x}}{\cos{x}}[/tex]

[tex]\sin{x} = \sqrt{2}\cos{x}[/tex]

The exact value of the cosine can be found applying the identity as follows:

sin²(x) + cos²(x) = 1.

Then, from the equation of the sine as a function of the cosine from the tangent relation, we have that:

[tex](\sqrt{2}\cos{x})^2 + \cos^2{x} = 1[/tex]

[tex]2^\cos^2{x} + \cos^2{x} = 1[/tex]

[tex]\cos^2{x} = \frac{1}{3}[/tex]

[tex]\cos{x} = \pm \sqrt{\frac{1}{3}}[/tex]

The angle is of the first quadrant, as 0° < x < 90°, hence the cosine is positive, thus:

[tex]\cos{x} = \frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{3}}{3}[/tex]

The identity that gives the sine for half the angle is:

[tex]\sin{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 - \cos{x}}{2}}[/tex]

Hence:

[tex]\sin{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 - \frac{\sqrt{3}}{3}}{2}}[/tex]

[tex]\sin{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 - \sqrt{3}}{6}}[/tex]

The identity for the cosine is almost the same, just there is a plus instead of a minus, hence:

[tex]\cos{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 + \cos{x}}{2}}[/tex]

[tex]\cos{\left(\frac{x}{2}\right)} = \sqrt{\frac{1 + \frac{\sqrt{3}}{3}}{2}}[/tex]

[tex]\cos{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 + \sqrt{3}}{6}}[/tex]

The tangent is the sine divided by the cosine, hence the inserting the entire division and the same square root and simplify the common denominator, thus:

[tex]\tan{\left(\frac{x}{2}\right)} = \sqrt{\frac{3 - \sqrt{3}}{3 + \sqrt{3}}}[/tex]

In this problem, we are given two points in the form [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex].

So, we can define the x's and y's as:

[tex]x_1 = 1[/tex], [tex]y_1 = 2[/tex], [tex]x_2 = 5[/tex], [tex]y_2 = 10[/tex].

Given:

A pole that is 2.5 m tall casts a shadow that is 1.65 m long. At the same time, a nearby building casts a shadow that is 50.25 m long.

Let x be the height of the building.

2.5/1.65 = x/50.25

2.5*50.25 = x * 1.65

25/10*5025/100 = x*165/100

25*5025/10 = 165x

25*5025 = 1650x

Given that two angles in triangle PQR are congruent, ∠P and ∠Q;

∠R measures 26.35°.

Let the measure of ∠P would be x

∠P = x = ∠Q

To find the equation for each situation in terms of t years.

also in how many years t' the number of students in both high schools would be same?

Given

The initial strength of school A = 900

the increasing rate of students = 30 students per year

i.e students in 1 year = 30

students in t years = 30t

Total students of school A after 't' years = 900+ 30t

⇒ A = 600+ 65t

The initial strength of school B = 750

increasing rate of students = 45 per year

i.e. student in 1 year = 45

⇒ student in 't' years = 45t

Total students of school B in 't' years = 950 + 30t

=> B=950+30t

Now to find no. of years 't' when students in both schools are the same i.e. A =B

Through reporting statistical results, we found that  [tex]r^{2}[/tex] is 0.22 and Cohen's [tex]d[/tex] is 0.52 when s = 8, and  [tex]r^{2}[/tex] is 0.04 and Cohen's [tex]d[/tex] is 0.21 when s = 20. It is also observed that when the variability of the scores in the sample, [tex]r^{2}[/tex] decreases, there is simultaneous decrease in the measures of effect size, Cohen's [tex]d[/tex] as well.

It is given to us that -

A random sample of n = 16 scores

Population with a mean of μ = 45

Sample mean is found to be M = 49.2

In Reporting Statistical results, there are two different effect sizes, namely eta-squared [tex]r^{2}[/tex] and Cohen's [tex]d[/tex].

Eta-square, [tex]r^{2} = \frac{t^{2} }{t^{2}+df }[/tex]

where, [tex]df = n-1[/tex]

[tex]SEM = \frac{s}{\sqrt{n} }[/tex]

and, [tex]t=\frac{x_{2} -x_{1} }{SEM}[/tex]

Cohen's [tex]d=\frac{x_{2} -x_{1} }{s}[/tex]

a) Given that the sample standard deviation is s=8

We have n = 16

So, [tex]df = n-1 = 16-1 = 15[/tex]

[tex]SEM = \frac{s}{\sqrt{n} } = \frac{8}{\sqrt{16} } = \frac{8}{4} = 2[/tex]

We also have μ = 45 and M = 49.2. This implies

[tex]t=\frac{x_{2} -x_{1} }{SEM} = \frac{49.2-45}{2} = \frac{4.2}{2} =2.1[/tex]

Now,

[tex]r^{2} = \frac{t^{2} }{t^{2}+df } = \frac{(2.1)^{2} }{(2.1)^{2}+ 15 }= \frac{4.41}{4.41+15} \\= \frac{4.41}{19.41} = 0.22[/tex]

Cohen's [tex]d=\frac{x_{2} -x_{1} }{s} = \frac{49.2-45}{8} = \frac{4.2}{8} = 0.52[/tex]

b) Given that the sample standard deviation is s=20

We have n = 16

So, [tex]df = n-1 = 16-1 = 15[/tex]

[tex]SEM = \frac{s}{\sqrt{n} } = \frac{20}{\sqrt{16} } = \frac{20}{4} = 5[/tex]

We also have μ = 45 and M = 49.2. This implies

[tex]t=\frac{x_{2} -x_{1} }{SEM} = \frac{49.2-45}{5} = \frac{4.2}{5} =0.84[/tex]

Now,

[tex]r^{2} = \frac{t^{2} }{t^{2}+df } = \frac{(0.84)^{2} }{(0.84)^{2}+ 15 }= \frac{0.706}{0.706+15} \\= \frac{0.706}{15.706} = 0.04[/tex]

Cohen's [tex]d=\frac{x_{2} -x_{1} }{s} = \frac{49.2-45}{20} = \frac{4.2}{20} = 0.21[/tex]

c) Comparing a and b, we see that the variability of the scores in the sample, [tex]r^{2}[/tex] is 0.22 when s = 8 and [tex]r^{2}[/tex] is 0.04 when s = 20. Similarly, Cohen's [tex]d[/tex] is 0.52 when s = 8 and [tex]d[/tex] is 0.21 when s = 20.

Thus, we can see that when the variability of the scores in the sample, [tex]r^{2}[/tex] decreases, there is simultaneous decrease in the measures of effect size, Cohen's [tex]d[/tex] as well.

Therefore, through reporting statistical results, we found that  [tex]r^{2}[/tex] is 0.22 and Cohen's [tex]d[/tex] is 0.52 when s = 8, and  [tex]r^{2}[/tex] is 0.04 and Cohen's [tex]d[/tex] is 0.21 when s = 20. It is also observed that when the variability of the scores in the sample, [tex]r^{2}[/tex] decreases, there is simultaneous decrease in the measures of effect size, Cohen's [tex]d[/tex] as well.

If the chef follows the recipe proportions, then the true statement is;

A: The chef uses 3/16 cup of flour for every cup of water because 1/8 ÷ 2/3 = 3/16

Fractions can be presented in the form of word problems just like algebraic word problems.

Now, we are told that the chef uses 2/3 cup of flour for every 1/8 cup of water in a dough recipe.

This means that;

2/3 cup of flour = 1/8 cup of water

Thus;

1 cup of flour = (1 * 1/8)/(2/3) = 3/16 cups of flour for every cup of water

Looking at the given options, we can conclude that the only correct one based on our answer is Option A.
