If the point
is on the unit circle, what is x?

Answer:

1.Polygon

Step-by-step explanation:

Notice that

1. A triangle is a Polygon.

2. The triangle can be classified into Right, Obtuse, and Acute triangles.

3. An acute triangle is a triangle in which each angle is a acute angle. All acute triangle angles are less than 90 degrees. For example, an equilateral triangle is always acute, since all angles( which are 60) are all less than 90.

Taking into account the above, we have that the concept map can be filled.

Then, the unlock code is PTROAE

1/5

Step-by-step explanation:

There are 25 possible outcomes. (5 for each number.  For example, the 5 that start with 2 are 2-2, 2-3, 2-4, 2-5, and 2-6.)

The ones that equal 8 are:

6-2

2-6

3-5

5-3

4-4

5 out of 25 is 5/25, or 1/5

Answer:

it has no real roots.

and the 2nd answer is correct.

Step-by-step explanation:

Answer:

this quadratic equation has two roots:

x = (2+i√(2))/3 , (2-i√(2))/3

Steps:

3x²-4x+2​=0

x = (4±√((-4)²-4×3×2))/2×3

x = (4±√(16-24))/6

x = (4±√(-8))/6

x = (4±√(-2×4))/6

x = (4±√(-2)×√(4))/6

x = (4±i√(2)×2)/6

x = (2±i√(2))/3

x = (2+i√(2))/3 , (2-i√(2))/3

Answer:

C and A

Step-by-step explanation:

Part 1.

The area of a trapezoid is base 1 + base 2 divided by 2 times height.

Base 1 is 38, base 2 is 14, and the height is 16.

38 + 14 = 52, 52 / 2 = 26, and 26 x 16 = 416.

The answer is C, 416.

Part 2.

The area of a kite is diagonal 1 times diagonal 2 divided by 2. The length of diagonal 1 is 12 (on the left) + 12 (on the right) = 24. The length of diagonal 2 is 10 (on the top) + 18 (on the bottom) = 28.

28 x 24 / 2 = 336.

The answer is A, 336

Answer:

336

Step-by-step explanation:

In the figure, there are four triangles

Total Area = sum of four triangles areas

0.5(12*18)*2+0.5(12*10)*2=336

Answer:

125 cm^3

Step-by-step explanation:

The volume of a cube is given by length*width*height. In a cube, all sides are the same. Therefore, you can put in (5cm)*(5cm)*(5cm) and get 125 cm^3

Answer:

if the basketball player makes the shot, then the team will advance to the playoffs (option d)

Explanation:

statement a is incorrect because the reverse of a statement is not always true. for example, all girls are humans but not all humans are girls. as such, we do not know that if the basketball player does not make the shot, the team will not win the game.

statement b is also incorrect, and uses a similar line of reasoning as statement a.

statement c is incorrect as well, and also uses the same reasoning as statements a and b.

statement d is correct. the reasoning used here is that if [x], then [y]. if [y], then [z]. thus, if [x], then [z].

Answer:

  parallelogram

A shape with two pairs of parallel sides is a parallelogram. If an angle is something other than 90°, then the figure is not a rectangle.

Answer:

To round a number to the nearest hundred, you make it into the hundred that is closest. Take the number 246, for example, which is between 200 and 300. It is closer to 200. So 246 rounded to the nearest hundred is 200.

(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)

2x^2 + 3x + 4x - 9 = 2x^2 +7x -9

2x^2 + 7x - 9 - x^2 -7x = x^2 -9

The answer is : x^2 - 9

Answer:

7 minutes

Step-by-step explanation:

the trip takes 7 mins

Pilar puts the boat in a lake that travels 400 meters at a constant speed. The time. On the return, the speed was the same for 2 minutes and then increase by 10m/min. The time boat takes in return back = 8 minutes

The given information states that the away distance the boat traveled = 400 m

The time traveled at the same initial speed, v₁, by the boat on the way back = 2 minutes.

The increase in speed of the boat by Pilar =  10 m/min

The new speed, v₂ = v₁ + 10

The time for the return trip, t₂ = 60 seconds (1 minute) faster than the time for the trip, t₁

[tex]t_2 = t_i - 1[/tex]

Therefore we have;

[tex]v_i\times t_i = v_i \times 2 + v_2 \times (t_2-2) \\= 400\\v_i \times 2 + (v_i + 10) \times (t_2-2) = 400\\(v_i + 10) \times t_2 - 20 = 400\\[/tex]

but

[tex]v_i = \frac {400}{t} = \frac{400)}{t_2+ 1}[/tex]

Which gives;

[tex]\frac{(400) }{(t₂ + 1} + 10) \times t_2 - 20 = 400\\10\times ( t_2²+ 36·t_2-2)/(t_2+1) = 40010 \times t_2^²+ 10 \times t_2-420 = 0[/tex]

[tex]t_2^2+ t_2-42 = 0[/tex]

[tex](t_2 - 7)(t_2 + 6) = 0[/tex]

[tex]t_2 = 7[/tex] minutes or [tex]-6[/tex] minutes

Given that t₂ is a natural number, we have,

t₂ = 7 minutes

Whereby, [tex]t_2 = t_i - 1[/tex], we have;

[tex]7 = t_i - 1[/tex]

[tex]t_{i} = 1 + 7 = 8[/tex] Minutes

The trip normally takes 8 minutes

Answer:

The first term is -6 and common difference is 3

Step-by-step explanation:

The nth term of an arithmetic progression is expressed as;

Tn = a + (n-1)d

T3 = a+2d

T4 = a + 3d

If the third term of an arithmetic sequence less than the fourth term by three

T3 = T4 - 3

a+2d = a+3d - 3

2d - 3d = -3

-d  = -3

d = 3

Similarly;

T7 = a+6d

T5 = a+4d

If the seventh term  is two times the fifth term, the;

T7 = 2T5

a+6d = 2(a+4d)

a+6d = 2a+8d

Since d = 3

a + 6(3) = 2a + 8(3)

a+18 = 2a + 24

a-2a = 24 - 18

-a = 6

a = -6

Hence the first term is -6 and common difference is 3

Answer:

Step-by-step explanation:

Factoring is taking apart products. It helps immensely if you are familiar with how products are formed. That is, it helps to be familiar with your multiplication tables and the rules of divisibility. It also helps to have  thorough understanding of the distributive property and the forms produced by the multiplication of binomials.

The first step is to look for any factors that are common to all of the terms you are factoring. Next steps include ...

__

1.1.1 4x -x^2

There is only one constant, so no constant factors. The variable x appears in all terms, with a lowest power of 1, so x^1 = x is a factor.

  = x(4 -x) . . . . . . . cannot be factored further

__

1.1.2 x² -8y³ . . . . we assume this is the intended expression. (It helps to use appropriate (and consistent) exponent presentation: x^2 -8y^3, or x² -8y³.

There are no common numerical factors, no common variable factors, and the form is not the difference of squares or cubes. This expression cannot be factored.

__

1.1.3 x² +15x -54

This is a trinomial in a single variable (x), so may be factorable as the product of two binomials. The product of binomial factors will have the form ...

  (x -p)(x +q) = x² +(q-p)x -pq

This means we are looking for two factors of 54 that have a difference of 15. Here is where your familiarity with numerical factoring is helpful.

  54 = 54×1 = 27×2 = 18×3 = 9×6

Differences of the factors are 54-1=53, 25, 15, 3. The factor pair we're looking for is 18×3. Comparing that to the above form, we see that q=18 and p=3, so the factorization is ...

  = (x -3)(x +18)

__

1.1.4 6x²y -10xy +15x -25

There are no numerical or variable factors that are seen in all terms. However, we notice that pairs of terms have common factors. Factoring those out gives ...

  = (2xy)(3x -5) +5(3x -5)

At this point, we notice that (3x -5) is a factor of both of these terms, so we can factor it out. This gives the complete factorization ...

  = (2xy +5)(3x -5)

_____

Additional comment

Many methods are promoted for factoring trinomials. It is helpful to understand that the product of factors looks like ...

  (ax +b)(cx +d) = acx² +(ad+bc)x +bd

That is to say, the product of the x² coefficient and the constant term (ac·bd) will have factors (ad, bc) that have a sum equal to the linear term coefficient. Once you realize this, finding the factorization is not so difficult. You look at the factor pairs of abcd in the same way we looked at factor pairs of -54 in problem 1.1.3 above.
