The polynomial-like expression is satisfied by the real value x = 1.
How to determine the real solution of a polynomial-like expression
In this question we must apply the concepts of logarithms and algebra properties to solve the entire expression. Initially, we expand the right part of the expression:
[tex](2^{x}-4)^{3}+(4^{x}-2)^{3} = (4^{x}+2^{x}-6)^{3}[/tex]
[tex](2^{x}-4)^{3} + (4^{x}-2)^{3} = [(2^{x}-4)+(4^{x}-2)]^{3}[/tex]
[tex](2^{x}-4)^{3}+(4^{x}-2)^{3} = (2^{x}-4)^{3}+3\cdot (2^{x}-4)^{2}\cdot (4^{x}-2)+3\cdot (2^{x}-4)\cdot (4^{x}-2)^{2}+(4^{x}-2)^{3}[/tex]
[tex]3\cdot (2^{x}-4)^{2}\cdot (4^{x}-2)+3\cdot (2^{x}-4)\cdot (4^{x}-2)^{2} = 0[/tex]
[tex]2^{x}-4 + 4^{x}-2 = 0[/tex]
[tex]2^{x}\cdot 2^{x} + 2^{x}-6 = 0[/tex]
[tex]u^{2}+u - 6 = 0[/tex]
[tex](u+3)\cdot (u-2) = 0[/tex]
Hence, the roots of the pseudopolynomial are [tex]u_{1} = -3[/tex] and [tex]u_{2} = 2[/tex]. Only the second one have a real value of x. Hence, we have the following solution:
[tex]2^{x} = 2[/tex]
[tex]x\cdot \log 2 = \log 2[/tex]
[tex]x = 1[/tex]

We would like to find the slope of the line of the given equation .
[tex]\longrightarrow y =\dfrac{3}{4}x -1 [/tex]
We know that slope intercept form of the line is given by ,
[tex]\longrightarrow y = mx + c [/tex]
where ,
m is the slope c is y interceptNow we can compare the given equation with the slope intercept form to find the slope . You will see that 3/4 is present at the place of m .Therefore ,

Hence option C is correct choice .
Answer:
C. 3/4 (third option).Step-by-step explanation:
Use the slope-intercept formula.
Slope-intercept formula:
→ y=mx+b
The m represents the slope.The b represents the y-intercept.So, the slope is 3/4 and y-intercept is -1.
Therefore, the correct answer is C. 3/4.I hope this helps! Let me know if you have any questions.

The surface area of a cuboid is the area of all the six faces of a cuboid. The Paint that is required to paint 3 boxes is 13 pints.
What is the surface area of a cuboid?The surface area of a cuboid is the area of all the six faces of a cuboid. It is given by the formula,
[tex]\rm \text{Surface area of the box}= 2[(Length \times width)+(Width \times Height)+(Length \times height)][/tex]
As it is given the dimensions of the storage box are a length of 8 feet, a width of 5 1/2 feet(5.5 feet), and a height of 4 1/2 feet(4.5 feet). Therefore, the surface area of the box can be written as,
[tex]\rm \text{Surface area of the box}= 2[(Length \times width)+(Width \times Height)+(Length \times height)][/tex]
[tex]\rm \text{Surface area of the box}= 2[(8\times 5.5)+(5.5\times 4.5)+(8 \times 4.5)] = 209.5\ ft^2[/tex]
As it is given that the surface area that can be covered with a pint of paint is 50 square feet, therefore, the paint that will be required to paint 209 square feet is,
[tex]\text{Paint Required} = \dfrac{\text{Total area that is needed to be paint}}{\text{Area covered in a pint of paint}}[/tex]
[tex]\rm \text{Paint Required} = \dfrac{209.5}{50} = 4.19\ pints[/tex]
Now, we know that the surface area of the box is 209 square feet, while the paint required to paint a complete box is 4.19, therefore, the paint that will be required to paint 3 boxes will be,
[tex]\text{Paint required to paint 3 boxes} = 3 \times 4.19 = 12.57 \approx 13[/tex]
Hence, the Paint that is required to paint 3 boxes is 13 pints.

Let x be a random variable with uniform distribution on (100,200). Find the probability that x assumes a value
Answers
The probability that x assumes a value less than three standard deviations from the mean is 1.
What is uniform distribution?The continuous uniform distribution, sometimes known as the rectangle distribution, is a family of symmetric probability distributions in probability theory and statistics.
We have:
x be a random variable with uniform distribution on (100,200).
It is required to find the probability that x assumes a value less than three standard deviations from the mean.
From the empirical rule, the data falls within three standard deviations of the mean in 99.7% of cases.
99.7% data from the (100, 200) is up to 199.7
Total number of favourable outcomes = 99.7
The probability that x assumes a value less than three standard deviations from the mean:
= 99.7/(200-100)
= 0.997 ≈ 1
Thus, the probability that x assumes a value less than three standard deviations from the mean is 1.

Nihkil surveyed 20 students at his middle school and 13 of them had at least one sibling. What percent of the students surveyed have at least one
sibling?
Answers
The students surveyed have at least one sibling are 65%.
What is percentage?The word "per centum," which means "by the hundred," was used to create the phrase "percentage." The denominator of a percentage is 100, which are fractions. To put it another way, it is the relationship between parts and the whole, where the whole always has a value of 100.
Rate is characterized as a given part or sum in each hundred. The denominator is 100, and the symbol "%" denotes that it is a fraction.
Given total student surveyed = 20
students had at least one sibling = 13
percent of the students surveyed have at least one sibling =
(students had at least one sibling)/(total student surveyed) x 100
percent of the students = 13/20 x 100
percent of the students = 65%
Hence 65% of students surveyed have at least one sibling.

Answer:
46°
Step-by-step explanation:
Since the side mn is tangent, the angle in M is a right angle. The sum of internal angles needs to add to 180°, so subtacting you're left with 46°
Hi there!
Since MN is tangent to Circle K, we know that MK and MN are PERPENDICULAR.
Therefore, m∠M = 90°.
Since we now know two angles in the right triangle, we can solve for m∠K knowing that angles in a triangle sum up to 180°.
180° = ∠M + ∠N + ∠K
180° = 90° + 44° + ∠K
Combine like terms:
180° = 134° + ∠K
Subtract:
180° - 134° = ∠K
∠K = 46°
