The derivative of tanx in calculus is sec^2x, which represents the slope of the curve at any point x for the function tanx.

The derivative of a function measures how the function changes as its input changes. In calculus, the derivative is a concept that describes the rate at which a quantity changes.

In the context of your question, the derivative of tanx or tangent x is sec^2x or secant squared x. This is a standard result that is usually memorized in calculus courses and can be derived using the limit definition of the derivative and trigonometric identities.

To put it in simpler terms, if tanx were the equation of a curve, the derivative (sec^2x) would represent the slope of that curve at any point x. This is key to understanding how the function behaves at different points and predicting its future behavior.

Answer:

Infinitely many

Step-by-step explanation:

The height of a parallelogram can be found by solving the equation 'Area = base × height' given the area is 175 square centimeters and the height is 18 centimeters less than the base. The base 'b' and the height 'b - 18' form a quadratic equation that can be solved to find 'b', after which subtracting 18 will give the height.

The question is asking to find the height of a parallelogram given its area and a relationship between the base and the height. The area of a parallelogram is found using the formula Area = base × height. According to the given information, we know that the area is 175 square centimeters. The relationship between the base and the height of the parallelogram is such that the height is 18 centimeters less than the base. Therefore, we can denote the base as 'b' and the height as 'b - 18'. Plugging these into the formula for the area we get 175 = b × (b - 18).

To solve for 'b', we can set up and solve a quadratic equation. After finding the value of 'b', we can calculate the height by subtracting 18 centimeters from our value for 'b'. Let's go through the steps:

After solving the quadratic equation, we would get the value of 'b' and accordingly the value of 'b - 18' which is the height of the parallelogram in centimeters.

Yolanda's was 25 years old when they were married.

Step-by-step explanation:

Let,

Age of Xavier = x

Age of Yolanda = x + 4

Combined age = 126

According to given statement;

Xavier's age + Yolanda's age = 126

[tex]x+(x+4)=126\\x+x+4=126\\2x=126-4\\2x=122\\[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{122}{2}\\x=61[/tex]

Yolanda's age = x+4 = 61+4 = 65

Age when married = 65 - 40 = 25

Yolanda's was 25 years old when they were married.

Step-by-step explanation:

16/4=4 (to brother) 16-4=12 (whats remaining) 12/2=6 (to sister)

Ruby gives her sister 6 animals.

To find out how many animals Ruby gives her sister, we need to follow the instructions step by step. Ruby starts with 16 stuffed animals. She gives 1/4 of her collection to her brother, which is equal to 16 * 1/4 = 4. Now Ruby has 16 - 4 = 12 stuffed animals left. Then she gives half of the remaining animals to her sister, which is equal to 12 * 1/2 = 6. So Ruby gives her sister 6 animals.

If each grid square represents one block, then the number of box he walked will be 30 blocks.

Step-by-step explanation:

Tommy walks from his home to the mall and then walks to a movie theater.

His home is at (0,0), the mall is at (0,8) and the movie theater is at (7,8).

Now, distance from (0,0) to (0,8) is 8 units and the distance from (0,8) to (7,8) is 7 units.

So, total distance covered is (8 + 7) = 15 units.

After leaving the theater Tommy walks to the store before returning home.

The store is at (7,0).

Now, the distance from (7,8) to (7,0) is 8 units and the distance from (7,0) to (0,0) is 7 units.

So, total distance covered is (8 + 7) = 15 units.

If each grid square represents one block, then the number of the box he walked will be (15 + 15) = 30 blocks. (Answer)

Answer:

Darius needs [tex]26\frac{2}{3}[/tex] cups of bread cubes to make four batches of stuffing for a family reunion.

Step-by-step explanation:

Given:

bread cubes to make a batch of stuffing  =   6 2/3 cup

To Find:

Number of cups of bread cubes needed to make four batches of stuffing for a family reunion = ?

Solution:

According to the question, to make one batch of stuffing Darius needs [tex]6\frac{2}{3}[/tex] cups of bread cubes

So if he wants to make four batched, then the number of cups of bread cubes  will be four times  as needed for making one batch

Then

Number of cups of bread cubes needed to make four batches = 4 x  bread cubes needed to make a batch of stuffing

Number of cups of bread cubes needed to make four batches

=  [tex]4 \times 6\frac{2}{3}[/tex]

=>[tex]4 \times \frac{18+2}{3}[/tex]

=> [tex]4 \times \frac{20}{3}[/tex]

=>[tex]\frac{80}{3}[/tex]

=>[tex]26\frac{2}{3}[/tex]

Darius will need 80/3 cups of bread cubes to make four batches of stuffing for a family reunion.

To find out how many cups of bread cubes Darius will need to make four batches of stuffing for a family reunion, we need to multiply the amount of bread cubes used in one batch by the number of batches he wants to make. Darius uses 6 2/3 cups of bread cubes in one batch. So, to find the total amount of bread cubes needed for four batches, we can multiply 6 2/3 cups by 4.

First, we convert the mixed number into an improper fraction: 6 2/3 = (6 * 3 + 2)/3 = 20/3.

Next, multiply the improper fraction by 4: (20/3) * 4 = 80/3 cups.

Therefore, Darius will need 80/3 cups of bread cubes to make four batches of stuffing for a family reunion.

The student's algebra problem is solved by gathering like terms, simplifying the equation, and then isolating 'w'. The solution to the equation is 'w = 9'.

The subject of this question is mathematics, specifically, the topic is algebra. The equation given is -4+w+17-2/3w=16. We need to solve this equation for 'w'.

To start, we should gather like terms. Therefore, -4 + 17 becomes 13, making our equation 13 + w - 2/3w = 16. We can also rearrange this to w - 2/3w instead, which results in 1/3w = 16 - 13, therefore, 1/3w = 3. To solve for w, we can multiply the both sides of the equation by 3, which leads to w = 3 * 3 or w = 9.

Answer: [tex]x=-25[/tex]

Step-by-step explanation:

For this exercise it is necessary to remember the multiplication of signs:

[tex](+)(+)+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]

Then, having the following equation provided in the exercise:

[tex]4 + \frac{1}{5}x = -1[/tex]

You need to solve for the variable "x" in order to find its value.

To solve the equation, you can follow the steps shown below:

Step 1: You need to subtract 4 from both sides of the equation. Then:

[tex]4 + \frac{1}{5}x-(4) = -1-(4)\\\\ \frac{1}{5}x=-1-4\\\\ \frac{1}{5}x=-5[/tex]

Step 2: This is the final step. You must multiply both sides of the equation by 5 in order to find the value of the variable "x".

Then, you get the following result:

There are 162 base ball cards

Solution:

Let "a" be the number of baseball training cards

Let "b" be the number of basket ball training cards

Trent has a collection of 198 baseball and basketball training cards

Therefore,

a + b = 198 -------- eqn 1

He has 4.5 times as many baseball cards as basketball cards

Number of baseball cards = 4.5(number of basketball cards)

a = 4.5b --------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 2 in eqn 1

4.5b + b = 198

5.5b = 198

b = 36

Substitute b = 36 in eqn 2

a = 4.5(36)

a = 162

Thus there are 162 base ball cards

Trent have 162 baseball cards in his collection.

Trent has a collection of 198 baseball and basketball training cards, with baseball cards being 4.5 times as many as basketball cards. To find out how many baseball cards Trent has, we can set up a system of equations.

Let x be the number of basketball cards.

Since the number of baseball cards is 4.5 times the number of basketball cards, the number of baseball cards is 4.5x.

The total number of cards is 198, so x + 4.5x = 198.

Solving this equation, we find x = 36. Therefore, the number of baseball cards Trent has is 4.5*36 = 162 baseball cards.

The complete set of ordered pairs for the relation y = 2(x + 11), where x belongs to the set (-2, -1, 0, 1, 2), is {(-2, 18), (-1, 20), (0, 22), (1, 24), (2, 26)}.

The given equation is y = 2(x + 11), where x takes values from the set (-2, -1, 0, 1, 2). To find the corresponding y-values for each x-value, we substitute the given x-values into the equation and calculate the y-values.

For x = -2:

y = 2(-2 + 11) = 2 * 9 = 18

So, the ordered pair is (-2, 18).

For x = -1:

y = 2(-1 + 11) = 2 * 10 = 20

Ordered pair: (-1, 20).

For x = 0:

y = 2(0 + 11) = 2 * 11 = 22

Ordered pair: (0, 22).

For x = 1:

y = 2(1 + 11) = 2 * 12 = 24

Ordered pair: (1, 24).

For x = 2:

y = 2(2 + 11) = 2 * 13 = 26

Ordered pair: (2, 26).

Combining all these ordered pairs, we have the complete set of ordered pairs for the given relation:

{(-2, 18), (-1, 20), (0, 22), (1, 24), (2, 26)}.

Answer:3√(p/q)3

Step-by-step explanation: Find the cube root .

The law used to simplify the expression [tex]( (p/q)^3 \)[/tex] is the "Power of a Quotient" rule.

The correct option is (b).

The "Power of a Quotient" rule states that when a fraction is raised to a power, we can raise both the numerator and denominator to that power individually. Mathematically, it is represented as:

[tex]\[ \left(\frac{a}{b}\right)^n = \frac{a^n}{b^n} \][/tex]

Applied to the expression [tex]\( (p/q)^3 \)[/tex], we raise both[tex]\( p \) and \( q \)[/tex] to the power of 3:

[tex]\[ \left(\frac{p}{q}\right)^3 = \frac{p^3}{q^3} \][/tex]

This simplification allows us to express the original expression in terms of powers of the numerator and denominator separately. In other words, the exponent 3 is distributed to both [tex]\( p \) and \( q \), resulting in \( p^3 \)[/tex]in the numerator and [tex]\( q^3 \)[/tex] in the denominator.

Using this rule, we can handle expressions involving powers of fractions efficiently, breaking them down into simpler terms that are easier to work with or evaluate. It's particularly useful when dealing with algebraic expressions or equations where fractions with powers are involved, providing a systematic approach to simplification.

Answer:

The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.

Step-by-step explanation:

Let's find out the pattern Zack is using to water his garden, this way:

First week =  1 3/8  gallons of water

Second week = 1 3/4 gallons of water = 1 3/8 + 3/8 = 1 6/8 = 1 3/4

Third week = 2 1/8 gallons of water = 1 3/4 + 3/8 = 1 6/8 + 3/8 = 2 1/8

The constant of adding every week is 3/8 gallons, therefore,

Fourth week = 2 1/8 + 3/8 = 2 4/8 = 2 1/2 gallons of water

Fifth week = 2 1/2 + 3/8 = 2 4/8 + 3/8 = 2 7/8 gallons of water

The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.

Following the pattern of increasing water usage by 3/8 gallons each week, Zack will use 2 7/8 gallons of water in the fifth week.

Zack watered his garden with increasing amounts of water over the first three weeks. Since there is a pattern, we can deduce the amount of water he will use in the fifth week by identifying the pattern and then continuing it.

Observing the pattern, we see that Zack is increasing the amount of water by 3/8 gallons each week. The progression in gallons is:

Continuing this pattern:

Therefore, Zack will use 2 7/8 gallons of water on the fifth week.
