Answer:

The equation has three solutions:

x= [tex]\frac{1}{2} + \frac{1}{2} log_{2} (3)[/tex]

x=1    

x = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

||[tex]4^{x} - 3[/tex]|[tex]-2[/tex]| = 1

|[tex]4^{x} - 3[/tex]|[tex]-2[/tex] = 1                                                |[tex]4^{x} - 3[/tex]|[tex]-2[/tex] = - 1

|[tex]4^{x} - 3[/tex]| = 1+2                                                 |[tex]4^{x} - 3[/tex]| = -1+2

|[tex]4^{x} - 3[/tex]|=3                                                       |[tex]4^{x} - 3[/tex]| = 1

[tex]4^{x} - 3[/tex] =3                 [tex]4^{x} - 3[/tex] = - 3                     [tex]4^{x} - 3[/tex] = 1                 [tex]4^{x} - 3[/tex] = - 1

x= [tex]\frac{1}{2} + \frac{1}{2} log_{2} (3)[/tex]        x∉∅                                x=1                           [tex]x = \frac{1}{2}[/tex]

The union of these four solutions is: [tex]\frac{1}{2} , 1,[/tex] [tex]\frac{1}{2} + \frac{1}{2} log_{2} (3)[/tex]

I hope this is clearly and understandably written to you :)

Answer:

59.16  units

Step-by-step explanation:

Given that,

The length of rectangle, L = 13

The breadth of the rectangle, B = 6

The perimeter of the shaded region = perimeter of rectangle - 2(perimeter of semicircle)

[tex]P=13\times 6-[2\times \dfrac{2\pi r}{2}]\\\\=78-2\pi r\\\\=78-2\times 3.14\times 3\\\\=59.16[/tex]

So, the perimeter of the shaded region is 59.16  units.

Step-by-step explanation:

You need to add the values of x into the function

f(x)= 4(-1) + 3

f(x)= 4(0) + 3

f(x)= 4(1) + 3

f(x)= 4(2) + 3

Answer:

$108

Step-by-step explanation:

The selling price being marked down by 20% means that $585 was reduced by 20%

Selling price = $585 - ( 20% x $585)

$585 - (0.2 x $585) = $468

Markup from cost = selling price - cost price

$468 - $360 = $108

Answer:

-26

Step-by-step explanation:

-4(-2)^2 + 2(-2) - 6

-26

The value of equation [tex]-4x^{2}+2x-6[/tex] is -26 when x = -2

"An equation is a statement of equality between two expressions consisting of variables and/or numbers."

Substitute the value x = -2 in the given equation

[tex]=-4(-2)^{2}+2(-2)-6 \\=-4(4)-4-6\\=-16-4-6\\=-16-10\\=-26[/tex]

Hence, the value of the given equation is -26

Answer:

Irrational numbers is correct.

The required square root of 5 is an irrational number.

Given that,
The square root of 5, has a decimal expansion that does not end or repeat. To which set of numbers does it belong is to be determined.

In mathematics, a rational number is a number that can be described as the result of a fraction of value or does not have face value.

An irrational number is a type of real number which cannot be represented as a simple fraction or the values that have face value are irrational numbers. Example: √2, √3, and π are all irrational.

Here,
√5 = 2.2360679775..
Which is an irrational number.

Thus, the required square root of 5 is an irrational number.

The required triangle PQS and triangle QRS are similar triangles. Option D is correct.

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.

According to the diagram,
It can be inferred that triangle PQS and triangle QRS are similar to each other. The term "similar" implies that these two triangles have the same shape but can be different in size. Specifically, the corresponding angles of these triangles are equal, and the corresponding sides are in proportion.

Consider triangle, PQS, and triangle QRS

Angle S is the common angle in both the triangles
And angle Q is similar to angle R

So both the triangle are similar by AA similarity postulate

Therefore, option D is correct.

Answer:fraction of the quilt is white = 1/6

Step-by-step explanation:

Let the total quilt be  = 1 ( since we are dealing with fraction)

The portion of quilt that is green  2/6

The portion of quilt that is yellow  3/6

The portion that is white   = Total quilt  −( portion of quilt that is green and yellow)

=1−( 2/6 +  3/6 )

=1  −5/6

Answer: 4.4

Answer:

4.4

Step-by-step explanation:

Given:

Mary spent 30% of her budget in groceries.

She spent 42$ on groceries.

To find:

The total amount of her budget.

Solution:

Let x be the total amount of the budget.

Then, the amount spent on groceries is 30% of x.

[tex]\dfrac{30}{100}x=0.3x[/tex]

She spent 42$ on groceries.

[tex]0.3x=42[/tex]

Divide both sides by 0.3.

[tex]x=\dfrac{42}{0.3}[/tex]

[tex]x=140[/tex]

Therefore, the total amount of the budget is 140$.
