6.47 x 10-15
3.36 * 10-29 ​

Answer: B.)      18x^2y^2 3squareroot 3xy^2

Step-by-step explanation:

Answer:

B. [tex]18x^{2} y^{2} \sqrt[3]{3xy^{2} }[/tex]

Step-by-step explanation:

To simplify this expression, use the fact that the root of a number (in this case is the cube root)  can be expressed like a fractional exponent (1/3). Using this, the expression changes to:

[tex]3x(648x^{4}y^{8})^{(1/3)}[/tex]

Next step is to put the exponent inside the parenthesis:

[tex]3x(648^{1/3}x^{4/3}y^{8/3})[/tex]

Find the prime factorization  of 648:

648 =3⋅3⋅3⋅3⋅2⋅2⋅2

648=3⁴∗2³

[tex]3x(3^{(4/3)}2^{(3/3)}x^{4/3}y^{8/3})[/tex]

Change all improper fractions in exponent to mixed fractions

[tex]3x(3^{1(1/3)}2^{1}x^{1(1/3)}y^{2(2/3)})[/tex]

Separate integers exponents from fractional:

[tex]3x(3\cdot3^{(1/3)}\cdot 2 \cdot x\cdot x^{1/3}\cdot y^{2}\cdot y^{2/3})[/tex]

Re-arrange (all numbers with fractional exponents must be together):

[tex]3x(3 \cdot 2\cdot x\cdot y^{2}\cdot 3^{(1/3)}x^{1/3}y^{2/3})[/tex]

Multiply the 3x with the numbers that have an integer exponent:

[tex]18x^{2}y^{2}(3^{(1/3)}x^{1/3}y^{2/3})[/tex]

Take out  the exponent 1/3 from the parenthesis:

[tex]18x^{2}y^{2}(3xy^{2})^{1/3}[/tex]

And change the representation of the root to use a radical symbol

[tex]18x^{2} y^{2} \sqrt[3]{3xy^{2} }[/tex]

Answer:

C. h(2) = 16

True statement

Step-by-step explanation:

The function has

Domain

-3 ≤ x ≤ 11

Range

1 ≤ h(x) ≤ 25

h(8) = 19

h(-2) = 2

Lets analyze each statement

A. h(13) = 18

False, x = 13 is not part of the domain

B. h(-3) = -1

False, -1 is not part of the range

C. h(2) = 16

True statement

D. h(8) = 21

False, the problem tells us that h(8) = 19

Answer:

x = 4

Step-by-step explanation:

Using the 90-60-30 theorem, the hypotenuse is equal to 2a, so a = 4 sqrt(2). The shortest leg is therefore 4 sqrt(2). Using this, to find x, plug it into the smaller triangle. The hypotenuse of the smaller triangle is therefore 4 sqrt(2). Using the 45-45-90 theorem, 4 sqrt(2) = x sqrt(2), so x = 4. This is because there are two sqrt(2)'s', so taking that out of the equation leaves x = 4.

Hope this helps!

Answer:

y=2/3x+3

Step-by-step explanation:

the slope is 2 over 3 because you ride 2 up and 3 to the right to get to the next dot and the y intercept is 3 because that's where the line intercepts the y axis.

Answer: Undefined

Step-by-step explanation: Since there is no change in x, and it is a horizontal line, that means that the denominator is zero. Dividing anything with the denominator being 0 will always be undefined (Not to be confused with the numerator, which is just dividing by 0, thus giving you 0.) That means that our answer will be undefined.

Answer:

Step-by-step explanation:

It's 32, just follow the row when g=13.

Answer: We want to know f( g (13) ), here g(13) is just a number, so you are evaluating f in a number, first we need to know the value of g(13). Looking in the diagram you can see that g(13) = 16.

So f(g(13)) = f(16)

Also, looking in the diagram you can see that f(16) = 32

So, f ( g (32) ) = 32

Last option: 63

Step-by-step explanation:

You need to observe and analize the triangle XWZ provided in the image attached.

You can observe that the lenght of the side XW of the triangle XWZ is congruent to the lenght of the side ZW. This means that the lenght of the side XW and the lenght of the side ZW are equal.

Therefore, if the measure of the angle ∠X is 63, then the measure of the angle ∠YZW is 63:

Answer:

12x

Step-by-step explanation:

We require the lowest common multiple of 4x, 3 and 2x

the lowest common multiple of 4, 3 and 2 is 12

the lowest common multiple of x and x is x

Combining the two gives lowest common multiple of 12x

Multiplying through by 12x gives

72x - 9 + 4x = 6 + 60x ← no fractions

ANSWER

C. (0,4)

EXPLANATION

The given graph has equation:

[tex]y = 4( {3}^{x} )[/tex]

The y-intercept is where the graph touches the y-axis.

At this point the value of x is zero.

We substitute x=0 into the equation to obtain:

[tex]y = 4( {3}^{0} )[/tex]

Recall that any non-zero number exponent zero is 1.

This implies that,

[tex]y = 4( 1 ) = 4[/tex]

Hence the y-intercept is (0,4)

The correct answer is C.

Step-by-step explanation:

The ratio is the same each time (2/3), so this can be modeled as a geometric sequence.

an = a₁ (r)^(n-1)

where an is the nth term, a₁ is the first term, and r is the common ratio.

On the first rebound, the ball rises to 2/3 × 2 = 4/3, so a₁ = 4/3.

an = 4/3 (2/3)^(n-1)

On the sixth rebound, the ball rises to:

a₆ = 4/3 (2/3)^(6-1)

a₆ = 4/3 (32/243)

a₆ = 128/729

a₆ ≈ 0.176

Answer:

10 seconds.

Step-by-step explanation:

The velocity at which they are approaching each other = 59 + 41 = 1000 km per second.

Velocity = distance  / time

So time =  distance / velocity

= 1000 / 100

= 10 seconds.

10 seconds long does it take for them to collide.

Velocity exists as the measurement of the amount of distance an object covers in a given amount of time. Here's a term equation that describes the connection between distance, velocity, and time: Velocity equals distance traveled divided by the time it brings to get there.

The velocity at which they exist approaching each other = 59 + 41

= 1000 km per second.

Velocity = distance / time

So, time = distance / velocity

= 1000 / 100

= 10 seconds.

Therefore, 10 seconds long does it take for them to collide.

Answer:

$324.19

Step-by-step explanation:

First, find the price when marked down. Multiply 475 with 0.35:

475 x 0.35 = 166.25

Subtract 166.25 from the total cost:

475 - 166.25 = 308.75

Now, solve for the tax. Tax is 5% (0.05). Multiply 0.05 with the new cost:

308.75 x 0.05 = ~$15.44

Add 15.44 to the sales price:

308.75 + 15.44 = $324.19

$324.19 is your answer.

Answer: The 9th term is 6561

Step-by-step explanation:

The geometric sequences have the following formula

[tex]a_n = a_1(r)^{n-1}[/tex]

Where [tex]a_1[/tex] is the first term of the sequence and r is the common ratio between the consecutive terms of the sequence

In this case the sequence is   1 -3 9 -27

So [tex]a_1 = 1[/tex]

Observe that the common ratio  r is:

[tex]r=\frac{-3}{1}=\frac{9}{3}=\frac{-27}{9}=-3[/tex]

So the formula is:

[tex]a_n = (-3)^{n-1}[/tex]

We want to find [tex]a_9[/tex]

[tex]a_9 = (-3)^{9-1}[/tex]

[tex]a_9 = (-3)^{8}=6561[/tex]

Answer:

The direction of 5c + 4d is approximately 19.0° clockwise with

the positive part of x-axis

Step-by-step explanation:

* Lets talk about the direction of a vector

- If the vector is (x , y), then  

# Its magnitude is √(x² + y²)

# Its direction is tan^-1 (y/x)

- The direction is the angle between the positive part of x-axis and  

  the vector

* Lets solve the problem

∵ c = (2.4 , 0.45) and d = (7 , -4)

- To find 5c + 4d , multiply the two coordinates of c by 5 and the two

  coordinates of d by 4

# Multiply c by 5

∴ 5c = [5(2.4) , 5(0.45)]

∴ 5c = (12 , 2.25)

# Multiply d by 4

∴ 4d = [4(7) , 4(-4)]

∴ 4d = (28 , -16)

- Lets add 5c and 4d

∴ 5c + 4d = (12 , 2.25) + (28 , -16)  

∴ 5c + 4d = [(12 + 28) , (2.25 + -16)]

∴ 5c + 4d = (40 , -13.75)

- The vector is in the 4th quadrant because the x-coordinate is

 positive and the y-coordinate is negative

* Find the direction of 5c + 4d

∵ The direction is tan^-1 (y/x)

∴ The direction is tan^-1 (-13.75/40) = -18.97°

* The direction of 5c + 4d is approximately 19.0° clockwise with

 the positive part of x-axis

Answer:

If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.

2.5=5k

k=2.5/5

k=5.

K =5 is substituted in x=ky to find y where x is 10.

x=5y

10=5y

y=10/2

y=2

Answer:  The required value of y is 20.

Step-by-step explanation:  Given that y is 5 when x is 2.5 and y varies directly with x.

We are to find the value of y when x is 10.

According to the given information, we can write

[tex]y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~[\textup{where k is the constant of proportionality}][/tex]

When y = 5 and x = 2.5, then we have

[tex]5=k\times2.5\\\\\Rightarrow k=\dfrac{5}{2.5}\\\\\Rightarrow k=2.[/tex]

So, we get

[tex]y=2x.[/tex]

Therefore, when x = 10, then the value of y is

[tex]y=2\times10=20.[/tex]

Thus, the required value of y is 20.

Answer:

see explanation

Step-by-step explanation:

Given

2x² + 9x + 10 = 0

To factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × 10 = 20 and sum = + 9

The factors are + 4 and + 5

Use these factors to split the x- term

2x² + 4x + 5x + 10 = 0 ( factor the first/second and third/fourth terms )

2x(x + 2) + 5(x + 2) = 0 ← factor out (x + 2) from each term

(x + 2)(2x + 5) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - [tex]\frac{5}{2}[/tex]

Answer:

1. x = 2

2. x = - 5/2

Step-by-step explanation:  First put parenthesis around the equation

( 2x^2 + 4x ) + ( 5x + 10) = 0

2x ( x+ 2) 5 (x + 2),

when you have the same answer inside the parenthesis you know your right.

2x + 5 = 0

x + 2 = 0

Answer:

D

Step-by-step explanation:

We need to understand the meaning of slope. The slope means the rate of change of y with every unit change of x.

In our case, it will be rate of change of sales increase (%) with respect to unit change of discount(%).

The formula for slope is the change in y divided by change in x.

From the 2 points given, we can say that slope is:

[tex]\frac{62-32}{20-10}=\frac{30}{10}=\frac{3}{1}[/tex]

Answer:

D

Step-by-step explanation:

By definition for a right triangle with sides a, b, c, where c is the hypotenuse,

the following must be true:

a² + b² = c²

By using this formula on all the choices, we find that only D satisfies this formula

i.e.

for

a = √35 --------> a² = 35

b = √14 --------->b² = 14

c = 7 ------> c² = 49

a² + b² = 35 + 14 = 49 which is equal to the value of c² above

The correct answer is √35 , √14 , 7

Pythagoras' theorem that the square of a right triangle's hypotenuse is equal to the sum of the squares of the other two sides.

p^2 + b^2 = h^2 ( In a right angled triangle)

p = perpendicular of the triangle

b = base of the triangle

h = hypotenuse of the triangle

According to the Pythagoras theorem:

p^2 + b^2 = h^2 (In a right angled triangle)

In Option D

(√35)^2 + (√14)^2 = 7^2

49 = 49

Pythagoras theorem is followed in this triangle, hence it is a right angled triangle.
