What is Algebraic expression ?

An algebraic expressiοn is a statement in mathematics that can cοntain variables, integers, οperatοrs (including additiοn, subtractiοn, multiplicatiοn, and divisiοn), as well as grοuping symbοls like brackets.

The given expression is:

-24[tex]x^{5}[/tex] - 16[tex]x^{3}[/tex] = -8[tex]x^{3}[/tex] (? + 2)

To find the missing expression, we need to isolate the unknown factor, denoted by the question mark (?). We can begin by factoring out the common term of -8x³ from the left side of the equation:

-8[tex]x^{3}[/tex](3[tex]x^{2}[/tex] + 2) = -8[tex]x^{3}[/tex](? + 2)

Now, we can divide both sides by -8[tex]x^{3}[/tex], which gives:

3[tex]x^{2}[/tex] + 2 = ? + 2

Subtracting 2 from both sides yields:

3[tex]x^{2}[/tex] = ?

Therefore, the missing expression that was covered by the drop of ink is simply 3[tex]x^{2}[/tex].

Answer:

The expressions 10³÷10⁷, 10¹²/10¹⁶, and 10⁻²/10² are all equivalent to 10⁻⁴.

Step-by-step explanation:

When dividing exponents with the same base you subtract the exponents.

For visuals, in the equation 10³÷10⁷ it would be 10³⁻⁷ which would be 10⁻⁴ since 3 minus 7 is negative 4.

It is the same thing for 10¹²/10¹⁶, it would be 10¹²⁻¹⁶ which is equal to 10⁻⁴.

The same method can be used for 10⁻²/10² (10⁻²⁻²).

In response to the stated question, we may state that As a result, vector v has a magnitude of 6 and a direction of 160°.

A vector in mathematics is a mathematical object with both magnitude (or length) and direction. Vectors are frequently depicted as arrows, with the length of the arrow representing the magnitude and the direction of the arrow representing the vector's direction. A vector, for example, might represent an object's velocity, where the magnitude of the vector indicates the object's speed and the direction of the vector represents the direction of motion.  

Assuming that u has a magnitude of 3 and a direction of 160°.

Vector u can be represented by its components as follows:

3 cos(160°)i + 3 sin(160°)j = u

where I and j are unit vectors pointing in the x and y directions.

We now know that vector v = 2u, implying that the magnitude of vector v is:

|v| = |2u| = 2|u| = 2(3) = 6

As a result, the magnitude of vector v is 6.

We can use the fact that vector v is in the same direction as vector u but scaled by a factor of two to determine its direction. As a result, the vector v's direction is also 160°.

As a result, vector v has a magnitude of 6 and a direction of 160°.

C. The equation for transforming is g (x) = f (x) - 6.

What is transformation?

Shapes on a coordinate plane can be translated, rotated, and reflected using transformations. You can rotate, translate, or reflect any line, point, or vector.

A. The two types of transformations that can be used to transform f(x) to g(x) are translation and reflection.

Translation means shifting the graph left, right, up or down.

Reflection means creating a mirror image over x - axis or y - axis.

B. Both the transformations will have the same k value.

The graph g (x) is the translation of f (x) towards left with 6 units.

So, the value of k is -6.

Answer:

Step-by-step explanation:

Fractions represent a division problem where the numerator is divided by the denominator. For example, the fraction 3/4 represents the division of 3 by 4, which can be written as 3 ÷ 4. This is why it makes sense that fractions are about division.

Furthermore, fractions are used to represent parts of a whole or a group. When we divide a whole into equal parts, we are essentially dividing the whole into groups, with each group having the same size. For example, if we divide a pizza into 8 equal slices, each slice represents 1/8th of the pizza. We can also think of this as dividing the pizza into 8 equal groups, with each group having one slice.

Therefore, fractions are a natural way to represent division, as they allow us to express how many parts we have out of a whole or a group, and how big each part is relative to the whole or group.

To find the smallest total number of hot dogs that Yadira's mom can purchase, we need to find the least common multiple (LCM) of 12 and 9, since she wants the same number of hot dogs as hot dog buns.

The multiples of 12 are: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, ...

The multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...

The least common multiple of 12 and 9 is 36, since it is the smallest number that appears in both lists. Therefore, Yadira's mom should purchase 36 hot dogs (3 packs of 12) and 36 hot dog buns (4 packs of 9) for the family barbecue.

The percent increase in the annual student fees at the University of California between 2000 and 2014 is 125%.

What is percentage?

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

To find the percent increase, we need to calculate the difference between the two amounts and then divide that difference by the original amount, and finally multiply by 100 to express the result as a percentage.

The difference between the final amount ($9,000) and the initial amount ($4,000) is $5,000.

So the percent increase can be calculated as follows:

Percent increase = (difference / original amount) x 100%

= ($5,000 / $4,000) x 100%

= 125%

Therefore, the percent increase in the annual student fees at the University of California between 2000 and 2014 is 125%.

The total number of revolutions per minute tire makes when the car is traveling at a speed of 90 mi/hr and the tire has a diameter of 22 inches is equal to approximately 1375.09.

Diameter of a car tire = 22 inches

Speed of a car = 90mi/hr

Let us first convert the speed from miles per hour to inches per minute,

Since the diameter of the tire is given in inches.

90 mi/hr

= 90 × 5280 ft/hr

= 475200 ft/hr

= 475200 × 12 in/hr

= 5,702,400 in/hr

= 95,040 in/min

Number of revolutions the tire makes per minute,

Distance the tire travels in one revolution.

The circumference of a circle is given by,

C = πd

where C is the circumference and d is the diameter.

So the distance the tire travels in one revolution is,

d = π(22 in)

  = 69.115 in

Now, the number of revolutions per minute  is ,

=distance traveled per minute / distance traveled in one revolution

⇒ revolutions per minute = 95,040 in/min / 69.115 in/rev

⇒revolutions per minute ≈ 1375.09 rev/min

Therefore, the tire makes approximately 1375.09 revolutions per minute with tire of diameter of 22 inches.

An exponent of a fraction or rational number is said to have a rational exponent. With x as the base, p as the power, and q as the root 21, it may be represented as x(p/q). It can be transformed into the corresponding radical form,

for example, x(p/q) = (x(1/q))p = qxp 21. Similar rules apply to rational exponents and integer exponents 1.

With a rational exponent, the expression 3√24 can be expressed exponentially as follows:

The ramp will rise 11.6 inches from the ground at its highest end.

11.6 in.

Step-by-step explanation:

In this example we can use the sine function to determine how high the ramp will rise from the ground.

The definition of the sine function is

[tex]\sf \sin x= \dfrac{opposite}{hypotenuse}[/tex]

[tex]\sf \sin x= \dfrac{O}{H}[/tex]

In this case we are looking to evaluate the length of the opposite side.

We can rearrange the equation to isolate [tex]\sf O[/tex].

Multiply both sides of the equation by [tex]\sf H[/tex].

[tex]\sf H \cdot \sin x= \dfrac{O}{H} \cdot H[/tex]

Cancel the common factor of [tex]\sf H[/tex] on the right side leaves us with

Answer: 8.5 feet

Step-by-step explanation:

To determine how far Max traveled, we can use the Pythagorean theorem to find the distances between the points.

Max twirls to Lindsey's position:

Since Max is 2 feet behind Kenji and 4 feet left of Lindsey, Max and Lindsey form a right triangle with legs of 2 feet and 4 feet. Using the Pythagorean theorem:

a² + b² = c²

2² + 4² = c²

4 + 16 = c²

20 = c²

Taking the square root of both sides:

c = √20 ≈ 4.47 feet (rounded to the nearest tenth)

Max leaps to Kenji's position:

Since Max was initially 2 feet behind Kenji, the distance between Lindsey and Kenji is also 2 feet.

Max walks back to his original position:

The distance between Max's original position and Kenji's position is 2 feet.

Adding up the distances:

4.47 feet (Max to Lindsey) + 2 feet (Lindsey to Kenji) + 2 feet (Kenji to Max's original position) = 8.47 feet

So, Max traveled approximately 8.5 feet (rounded to the nearest tenth) during his movements.

The distance Max traveled can be found by calculating the distance of each movement he makes and adding them up. First, we need to use the Pythagorean theorem to calculate the distance between Lindsey and Max:

sqrt(4^2 + 2^2) = sqrt(16 + 4) = sqrt(20) = 2*sqrt(5)

So, Max travels 2*sqrt(5) feet to get to Lindsey's position. Next, he travels the distance between Kenji and Lindsey, which is 4 feet:

distance = 4

Finally, he travels in a straight line back to his original position, which is 2 feet straight behind Kenji:

distance = 2

Adding these distances together, we get:

2*sqrt(5) + 4 + 2 = 2*sqrt(5) + 6

Rounding to the nearest tenth gives us a final answer of approximately 8.5 feet.
