As Q is the midpoint of pr the value of qr will be 9 units

What is midpoint of line segment?

The midpoint divides the line segment into two equal parts.

Here in the question It is given that q is the midpoint of pr which implies  q will divide pq into two equal parts that is pq (x+8) equals qr (9x). now calculating x value first :

[tex]\begin{aligned}pq&=qr\\x+8&=9x\\8x&=8\\x&=1\end{aligned}[/tex]

Now, qr will be [tex]9x=9\cdot1=9[/tex]

Therefore, As Q is the midpoint of pr the value of qr will be 9 units

Answer:

1.26 feets

Step-by-step explanation:

Given the following :

Vertex (0, 0)

Focus of reflector = 6 feets

Extension = 5.5 feets

Equation to obtain conic section of a parabola:

(x - h)² = 4p(y - k)

Vertex (0, 0)

h =0 ; k = 0, p = 6, x = 5.5

(5.5 - 0)² = 4*6(y - 0)

30.25 - 0 = 24(y - 0)

30.25 = 24y

y = 30.25 / 24

y = 1.26

Hence, depth of reflector = 1.26 feets

The class expects to raise $122 from selling 110 cupcakes and 150 cookies at the given prices.

It seems like there is some incomplete or unclear information in your statement. However, I can provide you with some interpretation based on the information provided.

If the eighth graders sell cupcakes at $0.70 apiece and cookies at $0.30 apiece, the total amount of money raised can be represented by the expression 0.7p + 0.3k, where p represents the number of cupcakes sold and k represents the number of cookies sold.

The class expects to sell 110 cupcakes and 150 cookies. Plugging these values into the expression, we can calculate the total amount raised:

Total amount raised = (0.7 * 110) + (0.3 * 150)

= 77 + 45

= $122

Therefore, the class expects to raise $122 from selling 110 cupcakes and 150 cookies at the given prices.

Step by Step Explanation:

Its the right answer

The factor that could be part of the function so that f (x) decreases as x approaches infinity and as x approaches negative infinity is -(x + 4).

The function f(x) decreases as x approaches infinity and as x approaches negative infinity if and only if the degree of the polynomial in the denominator is greater than the degree of the polynomial in the numerator. This means that the factor that completes the function f(x) = (3x + 1)(2x - 5)(x + 9)

Let us analyze each of the factors:

(3x + 1) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(2x - 5) is also a linear factor that does not help in decreasing function as x approaches infinity and as x approaches negative infinity.

(x + 9) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(-4) is a constant term that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(-2/3x) is a linear factor that does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

5x² is a quadratic factor that is of degree 2 and thus does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

(3x-7) is also a quadratic factor that is of degree 2 and thus does not help in decreasing the function as x approaches infinity and as x approaches negative infinity.

-(x + 4) is a linear factor of degree 1 and it helps in decreasing the function as x approaches infinity and as x approaches negative infinity.

Answer:

Step-by-step explanation:

Given the differentials equation

dp/dt=kp(400-p)

dp/p(400-p) = kdt

Integrating both sides

1/200(lnp - ln(400-p)) = kt+C

(lnp - ln(400-p)) = 200kt+C

ln(p/400-p) = 200kt+C

p/400-p = Ce^200kt

At t = 0, P(t) = 100

On substituting

100/400-100 = Ce^200k(0)

100/300 = C

C = 1/3

Since the population is growing at 2 million per year, then at t = 1, p(t) = 102

1 = kp(400-p)

1 = k(102)(400-102)

1 = k(102)(298)

1 = 30396k

k = 1/30396

Next is to predict the population by 2010.

From 1960 to 2010, there are 50years

Using the expression

p/400-p = Ce^200kt.

p(50)/400-p(50) = 1/3e^200(50)/30396

p(50)/400-p(50) = 1/3e^10000/30396.

p(50)/400-p(50) = 1/3e^0.3289

p(50)/400-p(50) = 0.4631

P = (400-p)0.4631

p = 185.26-0.4631p

1.4631p = 185.26

p = 185.26/1.463

p = 126.63

Hence the country's population by 2010 is approximately 127million

Answer:

Step-by-step explanation:

For the given piecewise function,

Let the equation of the segment AB is,

y = ax + 7 where x < -2

Since a point (-2, 3) lies on the given line,

3 = a(-2) + 7

3 - 7 = -2a

a = 2

Therefore, f(x) = 2x + 7 when x < -2

For the segment BC,

f(x) = 3 where -2 ≤ x ≤ 2

For the segment CD,

f(x) = bx + 9

Since a point (2, 3) lies on this segment,

f(2) = 2b + 9 = 3

2b = 3 - 9

b = -3

Therefore, equation of segment CD will be,

f(x) = (-3)x + 9   where x > 2

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

m < PCA = m  < CAD ( alternate angles)

m < BAD = m <CAD ( given)

Also m < CAB = m < PCA + m < CPA  ( exterior angle of a triangle theorem).

Also m < CAB = m< CAD + m < BAD (given)

So  m < PCA + m < CPA =  m < CAD + m < BAD

But m < PCA = m  < CAD

so  m < CAD + m < CPA = m < CAD + m BAD

So m < CPA = m < BAD

But m < PCA = m < CAD = m BAD

therefore m < CPA = m < PCA

That makes triangle CAP isosceles

Therefore AP = AC.

Step-by-step explanation:

We have all the zeros of the polynomial. Therefore, there are no remaining zeros of f(x). The given polynomial f(x) is a degree 4 polynomial. The given zeros of f(x) are `3-5i`, `4i`, `3+5i` and `4-i`.

We have to find the remaining zeros of f.

The remaining zeros of f are the solutions of f(x) = 0 which are not given in the question. Degree of polynomial = 4

We are given all the four zeros of the given polynomial.

So, we can write the expression for f(x) by using all these zeros.

f(x) = a(x - 3 + 5i)(x - 3 - 5i)(x - 4i)(x - 4 + i) [Using the zero factor property]

Now, we have to find the remaining zeros.

Let's find it out :f(x) = a(x - 3 + 5i)(x - 3 - 5i)(x - 4i)(x - 4 + i)f(x)

= a[(x - 3)² - (5i)²][(x - 4)² - (i)²]

(Using a² - b² = (a + b)(a - b))f(x)

= a[(x - 3)² + 25][(x - 4)² + 1] (Since i² = -1)f(x)

= a(x² - 6x + 34)(x² - 8x + 17)f(x)

= a[x⁴ - 14x² + 33x + 612] (Expanding the above expression)

The polynomial f(x) is a degree 4 polynomial.

Hence, we have all the zeros of the polynomial. Therefore, there are no remaining zeros of f(x).

Answer:

s = 6 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the length of side )

Here A = 9[tex]\sqrt{3}[/tex] , thus

[tex]\frac{s^2\sqrt{3} }{4}[/tex] = 9[tex]\sqrt{3}[/tex] ( multiply both sides by 4 to clear the fraction )

s²[tex]\sqrt{3}[/tex] = 36[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

s² = 36 ( take the square root of both sides )

s = [tex]\sqrt{36}[/tex] = 6

The true statement is: "Octave is the name of a particular interval size."

In music theory, an octave refers to the interval between two pitches where the higher pitch has a frequency that is exactly twice that of the lower pitch. It represents a doubling or halving of the frequency. For example, if we start on the note A and move up to the next A, we have traversed an octave.

An interval, on the other hand, refers to the distance between two pitches. It is the numerical representation of the difference in pitch between two notes.

The statement mentioning "interval as the name of a particular octave size" is incorrect because the octave is a specific interval size, not the other way around.

The statement suggesting that "the fifth is a kind of octave" is also incorrect. The fifth is a specific interval that represents the distance of five diatonic scale steps between two pitches.

Lastly, the statement that "a synonym for distance is octave" is not true. While an octave represents a specific interval size, the term "distance" is a more general term that can refer to the measurement between any two pitches, regardless of the specific interval size.
