Apparently, you're supposed to recognize that the formula tells you the value of cos(x/2).

Answer:

Option D (As the x-values go to negative infinity, the function's values go to positive infinity).

Step-by-step explanation:

The graphed function shows a curve which has two turning points and three x-intercepts, which means it is a cubic polynomial. To check which statement is true, we will check all the statements one by one.

Option A) The graph shows that after the second turning point, the function starts to increase. Which means that as x-values increase, the function values will approach positive infinity. Therefore, option A is incorrect.

Option B) This option is incorrect because the graph explicitly shows that f(0) = 0, which means that when x = 0, the function value is also 0.

Option C) This option is incorrect because the function value is 0 at the x-value = 0, as shown in the graph. It can be also seen that As the x-values go to negative infinity, the function's values go to positive infinity since the value of the function decreases as the value of x decreases. Hence Option D is the correct answer!!!

Answer:

The correct option is D.

Step-by-step explanation:

Consider the provided graph of the function.

As the x values go to positive infinity or negative infinity the function value increase or goes to positive infinity.

The end behavior of the function is,

[tex]f(x)\rightarrow +\infty, as x\rightarrow -\infty[/tex]

[tex]f(x)\rightarrow +\infty, as x\rightarrow +\infty[/tex]

Now consider the provided options.

Option A is incorrect because As the x-values go to positive infinity, the function's values go to positive infinity.

Option B is incorrect because As the x-values go to zero, the function's values doesn't go to positive infinity.

Option C is incorrect because As the x-values go to negative infinity, the function's values are not equal to zero.

Option D is the correct option because As the x-values go to negative infinity, the function's values go to positive infinity.

Therefore, the correct option is D.

The correct option is C. Never The product of (a - b)(a - b) is always equal to a² - 2ab + b².

The product of (a - b)(a - b) can be expanded using the distributive property:

(a - b)(a - b) = a(a) - a(b) - b(a) + b(b)

Simplify by multiplying the terms:

= a² - ab - ab + b²

Combine like terms:

= a² - 2ab + b²

As you can see, the product of (a - b)(a - b) is a² - 2ab + b², not a² - b².

However, there is a well-known algebraic identity called the difference of squares, which states that a² - b² can be factored as (a + b)(a - b). So, the correct statement is:

(a - b)(a - b) is equivalent to a² - 2ab + b², not a² - b².

Therefore, the answer is C. Never the product of (a - b)(a - b) is always equal to a² - 2ab + b².

Answer:

2

Step-by-step explanation:

The degree of the vertex B is 2 because from vertex B there are 2 line segments coming out of it.

Another example, C has degree 4 because from it there are 4 line segments coming from it.

the first one

the degree of the polynomial in the numerator is 2.

the degree of the polynomial in the denominator is 2.

when the top and bottom have the same degree, like in this case, the horizontal asymptotes that that can afford us is simply the value of their coefficients.

[tex]\bf \cfrac{x^2-16}{x^2+2x+1}\implies \cfrac{1x^2-16}{1x^2+2x+1}\implies \stackrel{\textit{horizontal asymptote}}{y=\cfrac{1}{1}\implies y=1}[/tex]

for the second one

well, the degree of the numerator is 3.

the degree of the denominator is 2.

when the numerator has a higher degree than the denominator, there are no horizontal asymptotes, however, when the degree of the numerator is exactly 1 degree higher than that of the denominator, the rational has an oblique or slant asymptote, and its equation comes from the quotient of the whole expression, check the picture below, the top part.

for the third one

this one is about the same as the one before it, the numerator has exactly one degree higher than the denominator, so we're looking at an oblique asymptote, check the picture below, the bottom part.

Answer:

Base of the original triangle is 12 cm.

Step-by-step explanation:

Let base of triangle be x  

two equal legs  of triangles by y

therefore perimeter of triangle

                       x+y+y = 50 or x+2y =50

according to the question

 if base is x+3 and leg is y-4

then both are equal

   that is x+3 = y-4

            y-x = 7 or y =x+7

   x+2y =50

   x+2(x+7) = 50

    x+2x +14 =50

     3x +14 =50

     3x = 50 -14

      3x = 36

      x = 12

therefore base of the original  triangle is 12 cm                    

2222 = 2220 + 2 = 555 * 4 + 2

2333 = 2332 + 1 = 583 * 4 + 1

Then

2222 + 2333 = (555 + 583) * 4 + 3

leaving a remainder of 3.

2222 = 2220 + 2 = 370 * 6 + 2

2333 = 2328 + 5 = 388 * 6 + 5

Then

2222 + 2333 = (370 + 388) * 6 + 7 = (370 + 388 + 1) * 6 + 1

leaving a remainder of 1.

2222 = 2223 - 1 = 741 * 3 - 1

2333 = 388 * 6 + 5 = (388 * 2) * 3 + 5 = (388 * 2 + 1) * 3 + 2

Then

2222 + 2333 = (741 + 388 * 2 + 1) * 3 + 1

leaving a remainder of 1.

2222 = 555 * 4 + 2 = 185 * 3 * 4 + 2 = 185 * 12 + 2

2333 = 2400 - 67 = 2400 - 60 - 7 = (200 - 5) * 12 - 7

Then

Answer:

  y = (7/4)(x -4) +12

Step-by-step explanation:

The rate of growth is ...

  (19 in -12 in)/(8 wk -4 wk) = 7/4 in/wk

Using this slope in a point-slope form of the equation for a line, we get ...

  y = m(x -h) +k . . . . . line with slope m through point (h, k)

Answer:

  x = 5

Step-by-step explanation:

Ordinarily, one would not need the distributive property to solve this equation. It is quickly and easily solved by making use of the multiplication property of equality: multiply both sides of the equation by 1/3.

  3x(1/3) = 15(1/3)

  x = 5

___

To use the distributive property, we need the sum of two terms that have a common factor. We can get that form by subtracting 15 from both sides of the equation (subtraction property of equality):

  3x - 15 = 15 - 15 . . . . subtract 15

  3x -15 = 0 . . . . . . . . .simplify

Now, we can apply the distributive property to remove a factor of 3:

  3(x -5) = 0

And we can use the multiplication property of equality to multiply by 1/3:

  3(1/3)(x -5) = 0(1/3)

  x -5 = 0 . . . . . . . . . . simplify

Finally, we can add 5 to both sides of the equation (addition property of equality):

  x -5 +5 = 0 +5

  x + 0 = 5 . . . . . . simplify

  x = 5 . . . . . . . . . .simplify more

Answer: binomial probability

Step-by-step explanation:

A binomial probability indicates to the probability of having exactly x successes on n repeated trials in an particular binomial experiment which has only two possible outcomes.

If the probability of success on an single trial is b (which does not change) , then , the probability of failure will be (1-b)  .

The binomial probability for success in x trials out of n trials is given by :-

[tex]^nC_x\ b\ (1-b)^{n-x}[/tex]

Final answer:

The distribution called for a fixed number of independent trials with a constant success probability is the binomial probability distribution, defined by the equation P(X = x).

Explanation:

The probability distribution that shows the probability of x successes in n trials, where the probability of success does not change from trial to trial, is termed a binomial probability distribution. The key characteristics of a binomial distribution include a fixed number of independent trials with two possible outcomes (success or failure) and a constant probability of success in each trial.

Mathematically, the binomial distribution is defined using the equation P(X = x) = (n choose x) * px * qn-x, where p is the probability of success, q = 1 - p is the probability of failure, and (n choose x) is the combination of n taken x at a time.

The system of equations provided consists of a circle and a line:

1. [tex]\( x^2 + y^2 = 49 \)[/tex] (This represents a circle with a radius of 7, centered at the origin.)

2. [tex]\( y = -x - 7 \)[/tex] (This is a linear equation.)

The first equation has already been graphed, showing a circle with a radius of 7. To find the intersection points of the circle and the line, which are the solutions of the system, we can substitute the expression for y from the second equation into the first one:

[tex]\[ x^2 + (-x - 7)^2 = 49 \][/tex]

[tex]\[ x^2 + x^2 + 14x + 49 = 49 \][/tex]

[tex]\[ 2x^2 + 14x + 49 - 49 = 0 \][/tex]

[tex]\[ 2x^2 + 14x = 0 \][/tex]

[tex]\[ x(2x + 14) = 0 \][/tex]

This gives us two solutions for x:

[tex]\[ x = 0 \quad \text{or} \quad 2x + 14 = 0 \][/tex]

[tex]\[ x = 0 \quad \text{or} \quad x = -7 \][/tex]

Now we can substitute these x-values into the second equation to find the corresponding y-values:

For [tex]\( x = 0 \)[/tex]:

[tex]\[ y = -0 - 7 \][/tex]

[tex]\[ y = -7 \][/tex]

For [tex]\( x = -7 \)[/tex]:

[tex]\[ y = -(-7) - 7 \][/tex]

[tex]\[ y = 7 - 7 \][/tex]

[tex]\[ y = 0 \][/tex]

Therefore, the system of equations has two solutions where the line intersects the circle:

[tex]\[ (0, -7) \quad \text{and} \quad (-7, 0) \][/tex]

These calculations provide us with the step-by-step solution to the system of equations. The graphical solution would show the line [tex]\( y = -x - 7 \)[/tex] intersecting the circle [tex]\( x^2 + y^2 = 49 \)[/tex] at these two points.

Here is the graph showing the system of equations:

- The circle represented by [tex]\( x^2 + y^2 = 49 \)[/tex].

- The line represented by [tex]\( y = -x - 7 \).[/tex]

The red points indicate where the line intersects the circle, which are the solutions to the system of equations. These points are at (0, -7) and (-7, 0).

16= 8x^2

16/8 = x^2

x^2 = 2

x = sqrt(2)

The lengths of the sides

x = sqrt(2)      

other side =4

hypotenuse = 3*sqrt(2)

x = 1.4

other side= 4

hypotenuse = 3*1.4142

hypotenuse = 4.2

Answer:

4 feet, 1.4 feet, 4.2 feet

Step-by-step explanation:

We are looking for the lengths of the three sides of a right triangle. We are given that one leg has length 4ft. Let x be the length of the other leg. Since the hypotenuse of the right triangle is three times the length of this leg, we can represent the hypotenuse as 3x. This is a right triangle, so we can use the Pythagorean Theorem to find x.

42+x216+x2=(3x)2=9x2

Subtracting x2 from both sides, then dividing by 8 to isolate the x, we have

8x2x2x=16=2=±2–√

Considering only the positive value for x, the lengths of the three sides of the triangle are approximately 4 feet, 2–√≈1.4 feet, and 32–√≈4.2 feet.

Answer:

  573.6 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship of right triangle sides and angles:

  Tan = Opposite/Adjacent

This tells us ...

  tan(61°) = (height)/(distance to first point)

or

  distance to first point = height/tan(61°)

Likewise, ...

  distance to second point = height/tan(32°)

Then the difference of the distances is ...

  distance to second point - distance to first point

     = height/tan(32°) -height/tan(61°)

  600 ft = height × (1/tan(32°) -1/tan(61°))

Dividing by the coefficient of height, we have ...

  height = (600 ft)/(1/tan(32°) -1/tan(61°)) ≈ (600 ft)/(1.04603) ≈ 573.6 ft

Fill in the given values and solve.

  150.7968 hm = 2×3.1416×r

  (150.7968 hm)/6.2832 = r = 24 hm . . . . . divide by 2π

The radius of the circle is 24 hm.

Answer:

Step-by-step explanation:

For the equation ...

  y = a(x -h)² +k

you can find the x-intercepts by setting y=0 and solving for x.

  0 = a(x -h)² +k

  -k = a(x -h)² . . . . . . subtract k

  -k/a = (x -h)² . . . . . divide by a

  ±√(-k/a) = x -h . . . . take the square root

  h ± √(-k/a) = x . . . . add h . . . . this is the general solution

__

So, for each of your problems, fill in the corresponding numbers and do the arithmetic. If (-k/a) is a negative number, the square root gives imaginary values, so there is "no solution".

1.  x = 5 ± √9 = {5 -3, 5 +3} = {2, 8} . . . . the x-intercepts are 2 and 8

2.  x = -3 ± √(-2) . . . . . . no solution; the roots are complex

3.  x = 5 ± √(-8/4) . . . . . no solution; the roots are complex

Answer:

Step-by-step explanation:

These are all done the exact same way.  I'll do the first one in its entirety, and you can do the rest, following my example.

Finding x-intercepts means that you find the places in the polynomial where the graph of the function goes through the x-axis.  Here, the y-coordinates will be 0.  To find these x-intercepts, you have to set y equal to 0 and then factor.  First, though, we need to know exactly what the polynomial looks like in standard form.  The ones you have are all in vertex form.  We find the standard form by first expanding the binomial, like this:

[tex]0=(x-5)(x-5)-9[/tex]

FOIL those out to get

[tex]x^2-10x+25-9=0[/tex]

Combine like terms to get

[tex]0=x^2-10x+16[/tex]

Now we have to factor that.  I'll use regular old factoring, although the quadratic formula will work also.

In our quadratic, a = 1, b = -10 and c = 16

The product of a * c = 16.  The factors of 16 are:

1, 16

2, 8

4, 4

Some combination of those factors will give us a -10, the b term.  2 and 8 will work, as long as they are both negative.  -2 + -8 = -10.  Fit them into the polynomial with the absolute value of the largest number named first:

[tex]x^2-8x-2x+16=0[/tex]

Now we group them by 2's without ever changing their order:

[tex](x^2-8)-(2x+16)=0[/tex]

and then factor out the common thing in each set of parenthesis.  The common thing in the first set of parenthesis is an x; the common thing in the second set is a 2:

[tex]x(x-8)-2(x-8)=0[/tex]

Now the common thing is (x - 8), so we factor that out and group together in a separate set of parenthesis what's left over:

[tex](x-8)(x-2)=0[/tex]

By the Zero Product Property, either x - 8 = 0 or x - 2 = 0.  Solving the first one for x:

x - 8 = 0 so x = 8

Solving the second one for x:

x - 2 = 0 so x = 2

The 2 solutions are x = 2 and x = 8, choices a and d.

Answer:

20

4x will be 80

5x will be 100

Step-by-step explanation:

So those two how pink arrows means those opposite sides are parallel.

The side at the bottom is acting as a transversal through the parallel lines.

The angle that has measurement 5x and the one that has 4x are actually same-side interior angles; some people like to call it consecutive angles.

These angles add up to be 180 degrees when dealing with parallel lines.

So we have 5x+4x=180

which means 9x=180

Divide both sides by 9 giving us x=180/9

x=180/9=20.

The angle labeled 4x will then be 4(20) which is 80.

The angle labeled 5x will then by 5(20) which is 100.

To solve for x in vector problems, identify the axes, decompose each vector into its components using trigonometric functions, combine the components to find the resultant vector, and ensure that the solution is reasonable. Be sure to use radians for angles in calculations.

To find the value of x, we need to follow specific steps when dealing with vectors and their components. The given information suggests we have vectors A and B with specific magnitudes and angles relative to the x-axis. Here's how to proceed:

For example, given A = 53.0 m, θA = 20.0°, B = 34.0 m, and θB = 63.0°, we can find the x-components as Ax = A cos θA. It is important to use radians when calculations involve angles.

The law of cosines relates the three sides of a triangle with the cosine of the angle opposite one of them. It is useful for finding an angle of the triangle when only the side lengths are given, as here.

Answer:

The triangles are similar

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

step 1

In the right triangle FED

Find the length of side FD

Applying the Pythagoras Theorem

[tex]FD^{2}=FE^{2}+DE^{2}[/tex]

substitute the given values

[tex]FD^{2}=3^{2}+4^{2}[/tex]

[tex]FD^{2}=25[/tex]

[tex]FD^{2}=5\ units[/tex]

step 2

In the right triangle BUG

Find the length of side GU

Applying the Pythagoras Theorem

[tex]BG^{2}=BU^{2}+GU^{2}[/tex]

substitute the given values

[tex]10^{2}=6^{2}+GU^{2}[/tex]

[tex]GU^{2}=100-36[/tex]

[tex]GU^{2}=8\ units[/tex]

step 3

Find the ratio of its corresponding sides

If the triangles are similar

[tex]\frac{FD}{BG}=\frac{FE}{BU}=\frac{DE}{GU}[/tex]

substitute the given values

[tex]\frac{5}{10}=\frac{3}{6}=\frac{4}{8}[/tex]

[tex0.5=0.5=0.5[/tex] -----> is true

therefore

The triangles are similar

Answer:

the expected value is if your sum is odd because half of the values you could roll are odd witch means you have 50% chance to get odd

because their are not high odds of getting something good

Answer:

  -4432.5 m

Step-by-step explanation:

Displacement is measured in meters, so will be the product of velocity in m/s and time in s.

  (-98.5 m/s)×(45.0 s) = -4432.5 m

___

If you're concerned with significant figures, you can round this to -4430 m, which has the required 3 significant figures.

Answer:

-4432.5 m

Step-by-step explanation:

distance (or displacement) = rate times time.

Here, the displacement is

                                             (-98.5 m/s)(45.0 s) = -4432.5 m
