Answer:

1. 4/5, 3/5, 4/3 || 2. x = 13.78

Step-by-step explanation:

1)

Sin = Opposite/Hypotenuse = 16/20 = 4/5

Cos = Adjacent/Hypotenuse = 12/20 = 3/5

Tan = Opposite/Adjacent = 16/12 = 4/3

So the answer is 4/5, 3/5, 4/3

2) The unknown side is the opposite, and 21 is the hypotenuse. Opposite/Hypotenuse is the sine function.

Sin(41) ≈ 0.656

0.656 = x/21

x = 13.776

Solution:

Part - A:

To factor a polynomial, take out the factors of each term outside of the brackets. The terms of this expression are divisible by x⁴ (GCF), which can factorize completely. This will subtract 4 from the exponents.

=> x⁵ - x³=> x⁴(x - 1)

Part - B:

To factor a polynomial, take out the factors of each term outside of the brackets. The terms of this expression are divisible by 3 (GCF), which can factorize completely. This will divide 3 from the terms.

3x² - 753(x² - 25)3(x + 5)(x - 5)

Part - C:

To factor a polynomial, take out the factors of each term outside of the brackets. The terms of this expression are divisible by x²y (GCF), which can factorize completely.

3x⁵y + 4x⁴y - 5x²y=> x²y(3x³ + 4x² - 5)

Part - D:

Unfortunately, this expression can't factor with rational numbers. The expression results in 81x³ - 125.

Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex](x-3)^2[/tex] is [tex]x^2 - 6x + 9[/tex]

What is distributive property of multiplication over addition?

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

For the given case, the product needed can be calculated as:

[tex](x-3)^2 = (x-3) \times(x-3) = x(x-3) - 3(x-3) = x^2 - 3x - 3x + 9\\\\(x-3)^2 = x^2 - (3+3)x + 9 = x^2 - 6x + 9[/tex]

Express $18\sqrt 8$ in the form $a\sqrt b$, where $a$ and $b$ are integers and $b$ is as small as possible.

Answers

By simplifying the given expression we will get that:

18*√8 = 36*√2

How to find an equivalent expression?

Here we start with:

18*√8

We can rewrite 18 as:

18 = √324

Replacing that in our expression we get:

√324*√8 = √(324*8) = √(2,592)

Now we need to rewrite 2,592 as the product of a square number and a non-square number (such that the non-square number is the smallest possible one).

If we divide 2,592 by 2, we get:

2592/2 = 1296

Then we can rewrite:

√2592 = √(2*1296) = √2*√1296 = √2*36

So this is the expression we wanted:

18*√8 = 36*√2

Micah jogs on a path at the park at 5 miles per hour. He has jogged 2 miles when Luke starts running on the same path at 5 miles per hour. If they maintain their pace, when will Luke catch up to Micah?

Answers

Answer:

no because micah started before and they are running at the same pace.

Step-by-step explanation:

If they maintain their pace, Luke will not catch up to Micah because the gap of the 2 miles will be maintained.

What is the application of subtraction?

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

It is given that Micah jogs at a 5 mph pace along a park trail. Luke begins running on the same path at a speed of five miles per hour after he has jogged two miles.

After 2 kilometers of jogging by Micah, Luke begins running along the same route. Luke moves at a 5 mph speed.

Because Micah and Luke move at the same speed. There will be a 2-mile separation between them. Luke will not catch up to Micah

Thus, if they maintain their pace, Luke will not catch up to Micah because the gap of the 2 miles will be maintained.

Decide whether the given ordered pair is a solution to the system of equations.

-5x+y=12
y=-x
(-2,2)

Answers

Answer:

no

Step-by-step explanation:

Doesn't add to 12

[tex] - 5x + y = 12[/tex]

Add both sides 5x

[tex] - 5x + 5x + y = 5x + 12[/tex]

[tex]y = 5x + 12[/tex]

&

[tex]y = - x[/tex]

Thus :

[tex] - x = 5x + 12[/tex]

Add both sides x

[tex] - x + x = 5x + x + 12[/tex]

[tex]0 = 6x + 12[/tex]

Subtract both sides 12

[tex]0 - 12 = 6x + 12 - 12[/tex]

[tex] - 12 = 6x[/tex]

Switch sides

[tex]6x = - 12[/tex]

Divide both sides by 6

[tex] \frac{6x}{6} = \frac{ - 12}{6} \\ [/tex]

[tex]x = - 2[/tex]

We found the x-coordinate of the solution point ; to find the y-coordinate we just need to put the value of x in one 0f the given equations :

Can someone help me

Answers

Step-by-step explanation:

I guess, the problem is to understand :

what means "average" ?

well, the average of a defined set of data points is the sum of the data divided by the number of data points (or samples).

that way you get a mean value for each time the system is "measured" (a data point is created).

each new measurement / data point changes the mean value (or average).

this is used all the time - in sports statistics (e.g. the average score of a team), in daily life (like the average height of a human being that defines sizes of clothes, beds, chairs, tables, even the typical height of ceilings and so on).

the average of these 8 data points is therefore :

(36+37+34+23+47+27+31+21)/8 = 256/8 = 32

so, if he wants to raise his average score to 35 with the results of the next 2 games, this has 2 things to be considered :

1. the number of days points will be then 8+2=10 (and not just 8).

2. we need to add 2 data points, so that the sum of all 10 data points divided by 10 is then 35.

(36+37+34+23+47+27+31+21+x+y)/10 = 35

(36+37+34+23+47+27+31+21+x+y) = 350

x + y = 350 - 256 = 94

that means, he has to score a total of 94 points in the next 2 games.

it does not matter, how many in any single game, as long as the sum of both games is 94.

since the question is phrased "how many in each of the next 2 games", we simply take the target average of these 2 games.

remember, sum/amount = 94/2 = 47.

so, he would have to score 47 points in each of the next 2 games to raise his general average score to 35.
