(A) (x+4)(x²-4 x+4) (B) (x+4)(x²+4x+4) (C) (x+4)(x²-4 x+16) (D) (x+4)(x²+4 x+16)
The solution of factorization of x ³ + 64 is ( x + 4 )( x ² - 4 x + 16 ) [ Option C ].
The question asks to factorize the given polynomial, that is, x ³ + 64.
The question clearly states that we need to use the sum of cubes formula to factor the given polynomial x ³ + 64.
Sum of cube formula is given as
a ³ + b ³ = ( a + b ) ( a ² - a b + b ² ).
Substitute the values of variable a and b from the given polynomial x ³ + 64
x³ + 64 can be written as x ³ + 4 ³
=> a = x and b = 4
=> x ³ + 4 ³ = ( x + 4 ) ( x ² - 4 x + 4 ² )
=> x ³ + 4 ³ = ( x + 4 ) ( x ² - 4 x + 16 )
This matches with the option c among the multiple choices for this question.
Therefore, we get the solution of factorization of x ³ + 64 as ( x + 4 )( x ² - 4 x + 16 ).

The probability that 3 randomly selected points from A, B, C, and D are collinear is
(Type an integer or a simplified fraction.)
The probability that 3 randomly selected points from A, B, C, and D are collinear is; 3/4
How to Identify Collinear Points?
Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear.
Now, from the given image, there are 4 points but only three of them namely A, B and C are collinear. Thus, the 4 possible points picked could be; ABC, ABD, ACD, BCD
Thus, there are only three that can be collinear and so the probability is; 3/4

a. Before a basketball game, a referee noticed that the ball seemed under-inflated. She dropped it from 6 feet and measured the first bounce, as 36 inches and the second bounce as 18 inches. Write an exponential function to model the height of the ball.
The exponential function to model the height of the ball is
h = 72*[tex](1/2)^{n}[/tex]
According to the question we have been given that
at first bounce the height of the ball is = 36 inches
and at the second bounce the ball is at the height = 18 inches
The exponential model is given as
h = a.[tex]b^{n}[/tex] (1)
where h = height of the ball
n = number of bounces
Putting the different values of h and n in equation (1) and getting the value of a and b, we get
when h = 36 and n=1
36 = a.[tex]b^{1}[/tex]
36 = a.b (2)
when h = 18 and n =2
18 = a.[tex]b^{2}[/tex]
18 = a.b.b
18 = 36.b
b = 1/2
substituting the value of b in equation (2) we get
a = 72
Hence putting the value of a and b in equation (1), the exponential function to model the height of the ball is
h = 72*[tex](1/2)^{n}[/tex]

Which distribution is positively skewed? O A B. О с. D. HTT 6 10 02 4 6 8 10 12 14 16 18 20 22 24 26 28 30
So, this distribution is positively skewed.
What is positively skewed distribution?A positively skewed distribution, also known as a right-skewed distribution, is a type of distribution in statistics in which most values are centered around the left tail and the right tail is longer. The direction of outliers is revealed by skewness. A distribution curve's tail is longer on the right side when there is a positive skew. As a result, the distribution curve's outliers are more extreme to the right and closer to the mean to the left.
Given Data

Mean = 15.05
The distribution is said to be negatively skewed if the mean is lower than the mode. Positive skewness occurs when the mean exceeds the median in the distribution. The distribution is said to be negatively skewed if the mean is lower than the median.

Applying proportions, the decimal value is given by:
B. 32.064.
Santo got the wrong answer because he counted 6 and 4 as the tenths and hundredths digits, instead of hundredths and thousandths.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for digit values in a number.
For this problem, we just have to apply the digit values of the number to find the decimal value, adding the factors, hence:
3 x 10 = 30. (3 tens)2 x 1 = 2 (2 ones).6 x 1/100 = 0.06 (6 hundredths).4 x 1/1000 = 0.004 (4 thousandths).Hence:
30 + 2 + 0.06 + 0.004 = 32.064.

What statement is true about the sum of two rational numbers
Answer: The sum is always a rational number.
Step-by-step explanation:
Step-by-step explanation:
Given, sum of two rational numbers is always a rational number
We have to determine if the given statement is true or false
Consider two rational numbers 2/3 and 4/5
Sum of two numbers = 2/3 + 4/5
= [2(5) + 4(3)]/3(5)
= (10 + 12)/15
= 22/15
22/15 is a rational number.
Consider two rational numbers 2/3 and 1/3
Here, the denominators are same
Sum of two numbers = 2/3 + 1/3
= (2 + 1)/3
= 3/3
= 1/1
1/1 is also a rational number
Therefore, the given statement is true.

Using the change of base formula the evaluated value of [tex]log_{3} 33[/tex] is 3.184
Change of base formula is used to change the base of logarithm. It is used to write a logarithm of a number with a given base as the ratio of two logarithms each with the same base that is different from the base of the original logarithm.
According to the change of base formula :
[tex]log_{a} b = \frac{log_{x} b}{log_{x} a}[/tex]
where base x is base 10
According to the question, we have to find the value of [tex]log_{3} 33[/tex]
Thus applying change of base formula we get
[tex]log_{3} 33 = \frac{log_{10} 33}{log_{10} 3}[/tex]
calculating the value of log from the calculator we get,

Determine whether each logarithm is a common logarithm.
b. (log 64)
The logarithm function ( log 64 ) is not a common logarithm function as it does not have a base 10 but ahs a base e.
In mathematics, the common logarithm is the logarithm with base 10.
It is also known as the decadic logarithm and as the decimal logarithm function.
Here, we have the logarithm function as:
( log 64 )
Now, we can see that:
It does not have a base.
So, we will take the base as e.
So, it will not be a common logarithm function as having base 10 is an important characteristic of a common logarithm function.
Therefore, we get that, the logarithm function ( log 64 ) is not a common logarithm function as it does not have a base 10.

According to the statement
We have to find that the slope intercept equation.
So, For this purpose, we know that the
Slope-intercept form is the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
From the given information:
y - 3x = 8
y = 3x + 8
Slope = 3
And
Perpendicular lines have slopes that are negative reciprocals of each other. So, the new line will have a slope of = -1/3.
P(-4,1)
y - 1 = (-1/3)(x +4)
y - 1 = (-1/3)x - 4/3
y = (-1/3)x - 1/3.

b. Name an angle supplementary to RPS
c. Name a pair of complementary angles.
d. Name an angle adjacent to TPU.
1) The vertical angle will be
∠RPQ= ∠TPU
Vertical angles are angles opposite each other where two lines cross.
Vertical angles are pair angles formed when two lines intersect. Vertical angles are sometimes referred to as vertically opposite angles because the angles are opposite to each other. Real-life settings where vertical angles are used include; railroad crossing sign, letter “X'', open scissors pliers etc.
2) angle ∠QPR and angle ∠TPS are supplementary to ∠RPS
Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair
Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°. Similarly,
3) complementary angle will be
∠QPR and ∠RPS
When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
4) The adjacent angle will be ∠TPS
The two angles are said to be adjacent angles when they share the common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. Adjacent angles can be a complementary angle or supplementary angle when they share the common vertex and side.
