The value of x is 6 and the value of QR will be 8 units.

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

Given that the value of x and QR if Q is between P and R.

PQ=2x

QR=x + 2

PR= 5x -10

The value of x will be calculated as below:-

2x+x+2=5x-10

3x+2=5x-10

2=2x-10

12=2x

x = 12 / 2

x =6

The value of QR will be calculated as below:-

QR=x+2

6+2=8

Therefore, the value of x is 6 and the value of QR will be 8 units.

The Correct simplification is: (3².2x³y²)

Answer:

81x^6y^4

Step-by-step explanation:

Answer:

0.825

Step-by-step explanation:

In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5

33*2.5 = 66 + 16.5 = 82.5

33/40 = 82.5/100

Now we solve, 82.5/100 = 0.825

The pyrite cube is, well, a cube, so it has a side length s such that the area of its base is

s ² = 5.76 cm²

which means

s = √(5.76 cm²) = 2.4 cm

Then its volume is

s ³ = 13.824 cm³

Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of

(€785/cm³) × 13.824 cm³ = €10,851.80

Answer:

If I had guess, always equal since absolute numbers are always positive.

Answer:

I)

[tex]2a + 2b = -10\text{ or } 2a + 2b = 10[/tex]

II)

[tex]2a - 2b = -2 \text{ or } 2a-2b= 2[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaytstyle a^2 + b^2 = 13 \text{ and } ab= 6[/tex]

I)

Recall the perfect square trinomial pattern:

[tex]\displaystyle (a+b)^2 = a^2 + 2ab + b^2[/tex]

Rewrite:

[tex]\displaystyle (a+b)^2 = (a^2 + b^2) + (2ab)[/tex]

Substitute:

[tex]\displaystyle (a+b)^2 = (13) + (12)[/tex]

Evaluate:

[tex]\displaystyle (a + b)^2 = 25[/tex]

Take the square root of both sides:

[tex]\displaystyle a + b = \pm\sqrt{25} = \pm5[/tex]

Hence:

[tex]\displaystyle 2a + 2b = \pm 10[/tex]

Therefore:

[tex]\displaystyle 2a + 2b = -10 \text{ or } 2a + 2b = 10[/tex]

II)

Likewise:

[tex]\displaystyle (a-b)^2 = a^2 - 2ab + b^2[/tex]

Substitute:

[tex]\displaystyle (a-b)^2 = (13) -(12)[/tex]

Solve:

[tex]\displaystyle \begin{aligned} (a-b)^2 &= 1 \\ a-b &= \pm \sqrt{1} \\ a-b &= \pm 1\\ 2a - 2b &= \pm 2\end{aligned}[/tex]

In conclusion:

[tex]2a - 2b = -2 \text{ or } 2a-2b= 2[/tex]

Bot #11

Step-by-step explanation:

If you picked bot 12 in 5 second it produces 21 clicks which means if you add another 5 second it will be 10 second with 42 clicks. But, if you pick the bot with 17 clicks per 4 second, 8 seconds it will already be 34 clicks and 10 seconds half of 17 is  8/5 which in 10 seconds it produces 42.5 which shows the first bot produces more.

Answer:

  a) yes (a function)

  b) no (not a function)

Step-by-step explanation:

A functional relationship will have only one value of dependent variable for each value of independent variable. That is, the column on the left can only have one arrow tail per item.

__

a) is a function. Each independent variable maps to one dependent value

b) not a function. Independent variable values 7 and 30 map to two values each.

Answer:

area after 8 years is 2156km²

Step-by-step explanation:

Area of forest=4900 km²

decrease in area in 1 year=4900km² × 7%

decrease in area in 1 year= 343km²

decrease area in 8 years=343km² × 8

=2744km²

Remaining area= (4900-2744)km²

=2156km²

[tex]2^{-4 n}\times3^{-2 n} + 3^{-2 n}\times4^{-n}[/tex]

Step-by-step explanation:

Assuming you meant [tex]\frac{6^{2n}+1*9^n*4^{2n}}{18^n*2^n*12^{2n}}[/tex], the answer is [tex]2^{-4 n}\times3^{-2 n} + 3^{-2 n}\times4^{-n}[/tex].

Answer: Choice C.  p = 250(0.79)^t

Work Shown:

p = a*b^t

p = a*(1+r)^t

p = 250*(1+(-0.21))^t

p = 250(0.79)^t

Note that r = -0.21 is negative to indicate we have exponential decay.

Answer:

Yes.

Step-by-step explanation:

We want to determine if (x + 1) is a factor of the polynomial:

[tex]x^4 + 2x^3 + 2x^2 - 2x -3[/tex]

According to the Factor Theorem, if a binomial in the form (x - a) is a factor of a polynomial P(x), then P(a) must equal zero.

Our binomial factor is (x + 1) or (x - (-1)). Hence, a = -1.

Let our polynomial be P(x). Find P(-1):

[tex]\displaystyle\begin{aligned} P(-1) &= (-1)^4 + 2(-1)^3 +2(-1)^2 -2(-1) -3 \\&=0\end{aligned}[/tex]

Therefore, since the resulting value is indeed zero, (x + 1) is indeed a factor of the given polynomial.

In conclusion: yes.
