Answer:

[tex]\huge \boxed{\mathrm{D. \ 22}}[/tex]

Step-by-step explanation:

[tex]\mathrm{log_4 (x)=12}[/tex]

Make the base 4 from both sides.

[tex]\mathrm{4^{log_4 (x)}=4^{12}}[/tex]

Simplify the equation.

[tex]\mathrm{x=16777216}[/tex]

[tex]\mathrm{log_2 (\frac{x}{4} )}[/tex]

Let x = 16777216

[tex]\mathrm{log_2 (\frac{16777216}{4} )}[/tex]

[tex]\mathrm{log_2 (4194304)}[/tex]

Evaluate.

[tex]22[/tex]

Answer:

[tex]log_2(\frac{x}{4} )=22[/tex]

which is your answer "D"

Step-by-step explanation:

If    [tex]log_4(x)=12[/tex]  this means that : [tex]x=4^{12}[/tex] based in the definition of logarithm.

And this exponential expression can also be written using that [tex]4=2^2[/tex]:

[tex]x=4^{12}=(2^2)^{12}=2^{24}[/tex]

so now we know what x is with base 2 (which is needed for the second expression:

[tex]log_2(\frac{x}{4} )=?[/tex]

And this also can be written in exponent form (using the unknown "?" we need to find) as:

[tex]2^?=\frac{x}{4} \\x=4\,*\,2^?\\x=2^2\,*\,2^?\\x=2^{2+?}[/tex]

Since we know the value of x in base 2 (from our first analysis), then:

[tex]x=2^{2+?}=2^{24}\\then\\2+?=24\\?=22[/tex]

Therefore,

[tex]log_2(\frac{x}{4} )=22[/tex]

Answer: (0,4)

Step-by-step explanation:

Given: During one move in the game, a marker at a point (a,b) is first moved to the point (b,a) .                                                                     (i)

And then moved 3 units to the left.                                   (ii)

Translation rule to move a point (x,y) c units left : (x,y)→(x-c,y)

Now, (4,3)  first will become (3,4)  [using (i)]

Then, (3,4)→(3-3,4)=(0,4)   [using (ii) and translation rule]

Hence, During such a move, a marker that is at (4,3) will be moved to (0,4).

Complete Question:

In a jar there are 19 red jelly beans and 10 green jelly beans. In how many ways can you pick 4 red jelly beans and the same number of green jelly​ beans?

Answer:

[tex]Both = 813960[/tex]

Step-by-step explanation:

Given

Red Jelly Beans = 19

Green = 10

Required

Select 4 out of 19 red jelly beans and 4 out of 10 green jelly beans

The keyword in the question is pick and this implies combination;

4 from 19 red jelly beans is calculated as follows

[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]

Where n = 19 and r = 4

[tex]^{19}C_4 = \frac{19!}{(19-4)!4!}[/tex]

[tex]^{19}C_4 = \frac{19!}{15!4!}[/tex]

[tex]^{19}C_4 = \frac{19 * 18 * 17 * 16 * 15!}{15! * 4 * 3 * 2 * 1}[/tex]

[tex]^{19}C_4 = \frac{19 * 18 * 17 * 16}{4 * 3 * 2 * 1}[/tex]

[tex]^{19}C_4 = \frac{93024}{24}[/tex]

[tex]^{19}C_4 = 3876[/tex]

Similarly;

4 from 10 green jelly beans is calculated as follows

[tex]^{10}C_4 = \frac{10!}{(10-4)!4!}[/tex]

[tex]^{10}C_4 = \frac{10!}{6!4!}[/tex]

[tex]^{10}C_4 = \frac{10 * 9 * 8 * 7 * 6!}{6! * 4 * 3 * 2 * 1}[/tex]

[tex]^{10}C_4 = \frac{10 * 9 * 8 * 7 }{4 * 3 * 2 * 1}[/tex]

[tex]^{10}C_4 = \frac{5040}{24}[/tex]

[tex]^{10}C_4 = 210[/tex]

Ways of selecting both is calculated as follows

[tex]Both = 3876 * 210[/tex]

[tex]Both = 813960[/tex]

Answer:

Sampling Error

Step-by-step explanation:

We are told that the phenomenon is the naturally occurring difference between a sample statistic and the corresponding population parameter.

Now, it's sampling error because sampling error is simply defined as a deviation or difference in a sampled value as against the true population value due to the fact the sample is not a true representative of the population.

This is also similar to the definition given in the question.

Thus, it's sampling error!

Answer: It's not a rhombus

It would be a rhombus if all four sides were the same length, but we don't have that. Side DE is longer than EF, because the opposite angles are larger. We have 75 > 72, so that's why DE > EF.

Replace x with 3. Then simplify

f(x) = 4x+1

f(3) = 4(3)+1

f(3) = 12+1

Answer:

-4

Step-by-step explanation:

firt you add a minus one on both sides:

7n + 8 + 1 + (- 1) = -19 + (- 1) => 7n + 8 = -20

then add a minus eight on both sides:

7n + 8 + (- 8) = -20 + (- 8) => 7n = -28

finally in order to find (n) , devide both sides by seven:

7n ÷ 7 = (- 28) ÷ 7 => [ n = -4 ]

Answer:

D) 0 = 2(x + 5)(x + 3)

Step-by-step explanation:

Which of the following quadratic equations has no solution?

We have to solve the Quadratic equation for all the options in other to get a positive value as a solution for x.

A) 0 = −2(x − 5)2 + 3

0 = -2(x - 5) × 5

0 = (-2x + 10) × 5

0 = -10x + 50

10x = 50

x = 50/10

x = 5

Option A has a solution of 5

B) 0 = −2(x − 5)(x + 3)

Take each of the factors and equate them to zero

-2 = 0

= 0

x - 5 = 0

x = 5

x + 3 = 0

x = -3

Option B has a solution by one of its factors as a positive value of 5

C) 0 = 2(x − 5)2 + 3

0 = 2(x - 5) × 5

0 = (2x -10) × 5

0 = 10x -50

-10x = -50

x = -50/-10

x = 5

Option C has a solution of 5

D) 0 = 2(x + 5)(x + 3)

Take each of the factors and equate to zero

0 = 2

= 0

x + 5 = 0

x = -5

x + 3 = 0

x = -3

For option D, all the values of x are 0, or negative values of -5 and -3.

Therefore the Quadratic Equation for option D has no solution.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Calla lilies cost you $2.40.

roses cost $1.90.

If we need 65 lilies then it will cost

=64 * 2.40

= $153.60

and, If we need 65 roses then it will cost

Answer: g(x) = (x - 8)

Step-by-step explanation:

We start with the equation:

x^2 + y^2 - 16*x + 6*y + 73 = 100.

And we want to write this as:

g(x)^2 + (y + 3)^2 = 100.

So both equations are equal, then we can write this as:

x^2 + y^2 - 16*x + 6*y + 73 = g(x)^2 + (y + 3)^2

First we can expand the right side:

g(x)^2 + (y + 3)^2 = g(x)^2 + y^2 + 2*3*y + 9

Then we have:

x^2 + y^2 - 16*x + 6*y + 73 = g(x)^2 + y^2 + 6*y + 9

Now we can cancel the equal terms in each side, like y^2 and 6*y

x^2 - 16*x + 73 = g(x)^2 + 9

Now let's subtract 9 in each side:

x^2 - 16*x + 73 - 9 = g(x)^2

x^2 - 16*x + 64 = g(x)^2

Then we can assume that g(x) = (x - a)

then:

x^2 - 16*x + 64 = (x - a)^2 = x^2 - 2*a*x + a^2

-16*x + 64 = -2*a*x + a^2

now we must find the value of a, we have two equations:

-2*a = -16

a^2 = 64

and each equation yields to:

a = -16/-12 = 8.

a = √64 = 8

Then we have: g(x) = (x - 8)

Completing the squares, it is found that: [tex]g(x) = x - 8[/tex]

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

The expression given is:

[tex]x^2 + y^2 - 16x + 6y + 73 = 100[/tex]

To complete the squares:

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

Doing these steps:

[tex](x - 8)^2 + (y + 3)^2 = 100 - 73 + 8^2 + 3^2[/tex]

[tex](x - 8)^2 + (y + 3)^2 = 100 - 73 + 64 + 9[/tex]

[tex](x - 8)^2 + (y + 3)^2 = 100[/tex]

Which means that:

[tex]g(x) = x - 8[/tex]

The length of the straight line → BD is 74.22 mm.

A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.

Given is a line BD such that point C lies on BD. Also, BC = 52.39 mm and

CD = 21.83 mm.

We can say that for a straight line -

BD = BC + CD

The given measurements are -

BC = 52.39 mm

CD = 21.83 mm

Substituting the values, we get -

BD = 52.39 + 21.83

BD = 74.22 mm

Therefore, the length of the straight line → BD is 74.22 mm.

Answer:

b =0

Step-by-step explanation:

The only value where  |b| = -b  is when b=0

|0| = -0

0 = 0

Absolute value means non- negative

non-negative = negative

This is only true when we equal zero

Answer: b = 0 or anything negative (like b = -2)

So any value of b such that [tex]b \le 0[/tex]

==================================================

Explanation:

|b| is the distance from b on the number line to 0

The distance is never negative as negative distance does not make sense.

If b was some positive number, then |b| = b. For instance, |7| = 7. This shows 7 is seven units away from 0 on the number line.

----------

If b is negative or zero, then |b| = -b. Why? Because the result of |b| is the opposite of whatever negative b value you put in. For example, b = -2 leads to

|b| = |-2| = 2

while

-b = -(b) = -(-2) = 2

The two negatives cancel each other out to get a positive result.

This shows, |-2| = -(-2) = 2

Meaning that the location -2 is two units away from 0 on the number line.

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

4(x−7)=2(x+3)

Simplify both sides of the equation.

4(x−7)=2(x+3)

4x−28=2x+6

Subtract 2x from both sides.

4x−28−2x=2x+6−2x

x−28=6

Add 28 to both sides.

2x−28+28=6+28

2x=34

Divide both sides by 2.
