Apply Quoteint of Powers. Divide the intergers. serpately.

Note that Quotient of Powers is

[tex] \frac{a {}^{x} }{a {}^{y} } = a {}^{x - y} [/tex]

So the answer is

[tex]3 \times 10 {}^{ - 8 + 12} = 3 \times 10 {}^{4} [/tex]

The answer is

[tex]3 \times 10 {}^{4} [/tex]

Answer:

30000(thirty thousand) times larger

Step-by-step explanation:

9×10⁸ is the same as 900000000

3×10-¹² is the same as 0.000000000003

(9×10⁸)÷(3×10-¹²)

9÷3=3

10⁸÷10-¹²=10⁴

3×10⁴ which is 30000

Answer:

13

Step-by-step explanation:

Since the angles form 180 degrees, it will be what the equation is equal to.

Make the equation:

8r + 5 + 5r + 6 = 180

Combine like terms:

8r + 5 + 5r + 6 = 180

13r + 5 + 6 = 180

13r + 11 = 180

Solve:

13r + 11 = 180

       -11     -11

---------------------

     13r = 169

    ------   ------

      13      13

        r = 13

Given the function,

[tex]t(v) = \sqrt{ {v}^{2} + 2v - 8 } [/tex]

We are aware that square root function is defined for only non negative values.

So,

[tex]\to {v}^{2} + 2v - 8 \geqslant 0[/tex]

[tex] \to{v}^{2} + 4v - 2v- 8 \geqslant 0[/tex]

[tex]\to {v}(v + 4) - 2(v + 4) \geqslant 0[/tex]

[tex]\to(v + 4)(v - 2) \geqslant 0[/tex]

Therefore,

[tex]\boxed{\red{v\in (-\infty, -4] \cup [2,\infty})} [/tex]

Since this is the possible input values of v for which the given function is defined, it is the domain of the function.

  C)  x = 1/2 cm

Step-by-step explanation:

Apparently, we're to assume the units of x are centimeters. The volume of the cube is the product of its dimensions:

  V = x³ = 1/8

Then the value of x is ...

  x = ∛(1/8) = 1/∛8

  x = 1/2

12x – 4

Step-by-step explanation:

The sum of 5 times a number and - 4, added to 7 times the number =

(5x + -4) + 7x →

(5x + -4 + 7x) →

(5x + 7x + -4) →

(5x + 7x) + -4 →

12x + -4 →

12x – 4

Step-by-step explanation:

a refuse regular function tries to calculate a y value for a given x (input) value.

the inverse function turns this around and tries to calculate the x (input) value for a given y functional value.

e.g. when we know f(x) = 8, then what was the x value leading to this 8 fungible value ?

in order to turn this around, we solve the same functional equation for x instead of for y.

in our example here

f(x) = y = 3x -6

y + 6 = 3x

x = y/3 + 2

and now, to write the inverse function as normal function, we simply exchange the x and y names :

y = x/3 + 2

Answer:

d=150

Step-by-step explanation:

d=mass/volume

d= 300/2

d=150

mass(m)=300kg

volume(v)=2m^2

now,

d=m÷v

d=300÷2

d=150kg/m^3

The slope is -2. In context to this problem, the candle will burn away 2cm of its length every hour.

The slope of the equation, -2, means that the height of the candle reduces at a rate of 2 cm per hour.

Given the linear equation of the height of a candle that has been burning as: [tex]h = 28 - 2t[/tex].

This implies that:

28 in the equation represents the initial height of the candle = 28 cm.

-2 in the equation is slope, which is the rate of change at which the candle burns, meaning the height of the candle reduces by 2 cm every hour.

Therefore, the slope of the equation can be interpreted in the context of the problem as:

for every hour that passes, the height of the candle reduces by 2 cm.

The correct magnitude of the vector times the appropriate unit vector of given vectors are given as follows:

a. <0.708, 0, -0.708> [tex]*4.66*10^{-3}[/tex]

b. <0, -1, 0>*676

c. [tex]\overrightarrow{C} = <0.707, 0, -0.707>*4.47*10^2[/tex]

The general vector can be represented as:

[tex]\underset{A}{\rightarrow}[/tex] = (a, b, c) ......1

the magnitude [tex]| \right\underset{A}{\rightarrow} |[/tex] can be obtained as :

[tex]| \right\underset{A}{\rightarrow} | = \sqrt{a^{2}+ b^{2} +c^{2} }[/tex] .....2

and unit vector would be:

[tex]\hat{u}_A=\dfrac{\overrightarrow{A}}{|\overrightarrow{A}|}[/tex].......3

Solution:

a) ( 0.00330, 0, -0.00330)

here,

[tex]\underset{A}{\rightarrow} = ( 0.00330, 0, -0.00330)[/tex]

applying this magnitude to equation two:

[tex]| \right\underset{A}{\rightarrow} | = \sqrt{0.00330^{2}+ 0^{2} +(-0.00330)^{2} }[/tex] = [tex]4.66*10^{-3}[/tex]

the unit vector would be:

[tex]\hat{u}_A=\dfrac{\overrightarrow{A}}{|\overrightarrow{A}|}[/tex]

[tex]\hat{u}_A= < \frac{0.00330}{4.66*10^{-3}}, \frac{0}{4.66*10^{-3}}, \frac{-0.00330}{4.66*10^{-3}}>[/tex]

[tex]\hat{u}_A= <708, 0, -708>[/tex]

Thus, the vector [tex]{\overrightarrow{A}[/tex] would be - <0.708, 0, -0.708> [tex]*4.66*10^{-3}[/tex]

B) (0, -676, 0)

Solving simailarly like A),

Vector [tex]| \right\underset{B}{\rightarrow} | = \sqrt{0^{2}+ -676^{2} +0^{2} }[/tex] = 676

the unit vector would be:

[tex]\hat{u}_B=\dfrac{\overrightarrow{B}}{|\overrightarrow{B}|}\\\hat{u}_B= < \frac{0}{676}, \frac{-676}{676}, \frac{0}{676}>[/tex]

Thus,  the vector [tex]\overrightarrow{B}[/tex] = <0, -1, 0>*676

C) (0.00316, 0, -0.00316)

Attempting the third vector similarly we will get magnitude:

[tex]| \right\underset{C}{\rightarrow} | = \sqrt{0.00316^{2}+ 0^{2} +(-0.00316)^{2} }[/tex] = [tex]*4.47*10^{-3}[/tex]

Then,

[tex]\hat{u}_C=\dfrac{\overrightarrow{C}}{|\overrightarrow{C}|}\\\hat{u}_C= < \frac{0.00316}{4.47*10^2}, \frac{0}{4.47*10^2}, \frac{0.00316}{4.47*10^2}>[/tex]

The vector [tex]\overrightarrow{C} = <0.707, 0, -0.707>*4.47*10^2[/tex]

Answer:

  A

Step-by-step explanation:

It is generally useful to look at the answer choices. Here, we observe that all of them have y with a positive coefficient on the left side of the inequality. This makes it relatively easy to choose the set of inequalities that matches the graph.

The shading is below the solid line and above the two dashed lines. This means we are looking for a set of inequalities that looks like ...

  ay + ( ) ≤ ( ) . . . . . shading below a solid line

  y + ( ) > ( ) . . . . . . shading above a dashed line

  y + ( ) > ( )

The only set of inequalities with these relationships is choice A.

The equivalent value of the complex number 5i² will be -5.

The number can be written in the form of a+bi and is called a complex number. The complex number consists of two parts first is the real part and the second is the imaginary part.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

Given complex number is 5i². The equivalent expression can be written as:-

E = 5i²

E = 5 x ( -1 )²

E = 5 x -1

E = -5

Therefore, the complex number 5i² has an equivalent value of -5.
