The value of 6 = 3 × 2³ is 24 by using PEMDAS operations, the correct option is (d).
To understand why, we can simplify the equation using the order of operations, which is PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction). To evaluate the expression 3 x 2³, we first need to simplify the exponent, which means multiplying 2 by itself three times:
2³ = 2 x 2 x 2
2³ = 8
Now we can substitute the value of 2³ into the original expression:
3 x 2³ = 3 x 8
3 x 2³ = 24
However, the value of 6 = 3 x 2³, is equal to 24 the correct option is (d).

Find the number of permutations of the letters of the word MAKABAYAN?
Answer:
720
Step-by-step explanation:
The number of permutations of the letters of the word MAKABAYAN is 720. This is because the word MAKABAYAN has 9 letters, and the formula for calculating the number of permutations of a word with n letters is n! (n factorial). Therefore, 9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 720
A football player kicks a ball with an initial velocity of 47 feet per second. The initial height of the ball is 4feet
The ball traveled a horizontal distance of roughly 75.6*cos(theta) feet. Keep in mind that this is supposing a level, homogeneous surface and that the ball has no spin.
What is the equation?
In a math equation, two assertions are connected by the equals sign (=), which denotes equivalence. A mathematical assertion used in algebraic equations establishes the equivalence of two mathematical statements. For instance, in equation 3x + 5 = 14, the equal sign creates a space between the values 3x + 5 and 14.
To comprehend the relationship between the two sentences written on opposing sides of a letter, utilise a mathematical formula. The logo and the specific program typically correspond. An illustration would be 2x - 4 = 2.
75.6 feet are equal to ymax = 472/(2*32.2) + 4.
As the ball's motion is symmetrical, the time it takes to reach its highest point is equal to half the length of its flight. As a result, the total flight time is:
[tex]\frac{Sin(\theta)}{g} = 247;[/tex]
[tex]t_{total} = 2[/tex];
[tex]t_{max} = 247[/tex]
[tex]\frac{cos(\theta)*y_{max}}{vi^{2}},\\[/tex]
where t max is the time needed to reach the highest point. Again, we cannot precisely solve for theta, but we may leverage the knowledge that the ball's horizontal travels as follows:
[tex]Vi \ \times cos(\theta)\times t_{total} = x.[/tex]
Hence, by entering the data we are aware of, we can determine x:
x = 47cos(θ) (θ)
75.6/47 = [tex]\frac{2y_{max}}{vi}[/tex]
= 47cos(θ)75.6cos (θ).
Hence, the ball traveled a horizontal distance of roughly 75.6*cos(θ) feet. Keep in mind that this is supposing a level, homogeneous surface and that the ball has no spin.

A jar contains 0. 85 liter of strawberry juice and 0. 50 liter of mango juice. Celina poured 0. 15 liter of watermelon juice into the jar. She then drank 0. 30 liter of the mixture
An expression to represent the total amount of juice left in the jar is "Total amount of juice left in jar = Total amount of juice in jar before Celina drinks any - Amount of juice Celina drinks"
First, let's start by labeling the quantities of juice we have. We have 0.85 liters of strawberry juice, 0.50 liters of mango juice, and 0.15 liters of watermelon juice. When we combine these three quantities, we get the total amount of juice in the jar before Celina drinks any of it. We can express this as:
Total amount of juice in jar before Celina drinks any = 0.85 + 0.50 + 0.15
Simplifying this expression, we get:
Total amount of juice in jar before Celina drinks any = 1.50 liters
Now, we know that Celina drinks 0.30 liters of the mixture. So, the total amount of juice left in the jar after she drinks some can be expressed as:
Total amount of juice left in jar = Total amount of juice in jar before Celina drinks any - Amount of juice Celina drinks
Substituting in our values, we get:
Total amount of juice left in jar = 1.50 - 0.30
Simplifying this expression, we get:
Total amount of juice left in jar = 1.20 liters
Therefore, the expression that represents the total amount of juice left in the jar after Celina drinks 0.30 liters of the mixture is:
Total amount of juice left in jar = 1.50 - 0.30 = 1.20 liters

Line DE is tangent to circle A at point E. If line CD = 8cm and line DE = 12cm, what is the length of line BC. (You may assume A, B, C, and D are colinear)
Considering A, B, C, and D are colinear the length of line BC is 7cm.
In mathematics, a circle is a geometric shape that consists of all points that are the same distance from a fixed point called the center. This distance is called the radius of the circle. A circle is a two-dimensional object and is usually represented by a curved line, often drawn as a closed shape.
Since line DE is tangent to circle A at point E, we know that line AE is perpendicular to line DE. Therefore, we can use the Pythagorean theorem to find the length of AE:
AE² = AD²- DE²
Since A, B, C, and D are collinear, we can find AD by subtracting CD from BC:
AD = BC - CD
Substituting this into the equation above, we get:
AE² = (BC - CD)² - DE²
We are given that CD = 8cm and DE = 12cm, so we can substitute these values into the equation:
AE² = (BC - 8)² - 12²
We also know that AE = BE, since E is the point of tangency. Therefore, we can use the Pythagorean theorem again to find the length of BE:
BE² = AE² + AB²
Substituting AE^2 with the expression we found above, we get:
BE² = (BC - 8)² - 12² + AB²
Since A, B, C, and D are collinear, we know that AB + BC = CD = 8cm. Solving for AB, we get:
AB = 8 - B
Substituting this into the expression for BE², we get:
BE² = (BC - 8)² - 12² + (8 - BC)²
Simplifying this expression, we get:
BE^² = -16BC + 256
We want to find the value of BC, so we set BE equal to 12cm (since DE = 12cm):
12² = -16BC + 256
144 = -16BC + 256
-112 = -16BC
BC = 7 cm
Therefore,considering A, B, C, and D are colinear the length of line BC is 7cm.

A circle has centre at (0, 0) and passes through the point P(5, -12).
a) Determine the equation of the circle.
b) Determine the coordinates of the other endpoint of the diameter that passes through the point P.
a) The equation of the circle is x² + y² 169.
b) The coordinates of the other endpoint of the diameter are (-5, 12).
The equation of a circle is given by:
(x-a)² + (y-b)² = r²
Where (a, b) is the centre of the circle and r is the radius.
In this case, the centre of the circle is at (0, 0), so the equation of the circle simplifies to: x^2 + y^2 = r^2
To find the radius, we can use the distance formula between the centre and the point
P: r = √((5-0)^2 + (-12-0)²) = √(25 + 144) = √169 = 13
Therefore, the equation of the circle is: x² + y² = 13^2 or x² + y² = 169
To find the coordinates of the other endpoint of the diameter that passes through the point P, we can use the fact that the diameter is a straight line that passes through the centre of the circle. The slope of this line is: m = (-12-0)/(5-0) = -12/5
The equation of this line is: y = -12/5x
Since the other endpoint of the diameter also lies on the circle, we can substitute this equation into the equation of the circle: x² + (-12/5x)² = 169
Solving for x, we get: x = -5 or x = 5. Since the point P has an x-coordinate of 5, the other endpoint of the diameter must have an x-coordinate of -5.
Substituting this value of x back into the equation of the line, we get: y = -12/5(-5) = 12
Therefore, the coordinates of the other endpoint of the diameter are (-5, 12).
