[tex]\dfrac{\mathrm dr}{\mathrm d\theta}=\dfrac{\mathrm d(\theta\sin\theta)}{\mathrm d\theta}+\dfrac{\mathrm d(\cos\theta)}{\mathrm d\theta}[/tex]

By the product rule,

[tex]\dfrac{\mathrm d(\theta\sin\theta)}{\mathrm d\theta}=\dfrac{\mathrm d(\theta)}{\mathrm d\theta}\sin\theta+\theta\dfrac{\mathrm d(\sin\theta)}{\mathrm d\theta}=\sin\theta+\theta\cos\theta[/tex]

Answer:

3/8

Step-by-step explanation:

We can write 75% as a fraction, 75/100 and simplifying the fraction gives 3/4.

Then you have to multiply 1/2 * 3/4 which gives the result of 3/8.

Answer: 3/8

Step-by-step explanation:

First, I'm going to be using the 1/2 as .5

.5 x .75 = .375

.375 in fraction form is 375/1000

Simplified is 3/8.

Answer:

Part A) The proportional equation is [tex]c=55h[/tex]

Part B) 8 hours of training

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

Let

c -----> the cost to hire a dog

h ----> the amount of time in hours

The linear equation is equal to

[tex]c=kh[/tex]

Sue spent $660 on 12 hours of obedience training for her dog Muffin

Find the value of k (constant of proportionality)

[tex]k=y/x[/tex]

substitute the values

[tex]k=660/12=55[/tex]

therefore

The linear equation is

[tex]c=55h[/tex]

For [tex]c=\$440[/tex]

Find the value of h

substitute in the equation and solve for h

[tex]440=55h[/tex]

[tex]h=440/55=8\ hours[/tex]

Answer:

[tex]x\le 400-23\\ \\x\le 377\ pounds[/tex]

Step-by-step explanation:

The winner of a weight-lifting competition bench-pressed weight 400 pounds.

All other competitors bench-pressed at least 23 pounds less. So, the maximum weight that all other competitors bench-pressed is

[tex]400-23=977\ pounds[/tex]

If x pounds is the weight that the other competitors bench-pressed, then

[tex]x\le 400-23\\ \\x\le 377\ pounds[/tex]

that sounds as the other competitors bench-pressed at most 377 pounds weight.

Answer:

It is undefined or not a real number.

Step-by-step explanation:

There is no negative square root.

square root is a number multiplied by itself twice.

If you multiply a positive number by itself twice, you will get a positive number.

If you multiply a negative number by itself twice, you will get a positive number.

Therefore this is undefined or not a real number.

Answer:

Step-by-step explanation:

Answer:

a) 18 rows of bricks are needed

b) 2.25 times b

0.375 times (b - 1)

46.875 inches

18 rows

Step-by-step explanation:

* Lets explain how to solve the problem

a)

- The height of each brick is the shortest edge

- The shortest age is 2 1/4 inch ⇒ (2.25 inches)

- If b is the number of the rows of bricks

∴ The height of the bricks = 2.35 × b

- The height of the mortar is 3/8 inches ⇒ (0.375 inch)

- All rows of bricks covered by mortar on top except the last row

- The height of mortar = 0.375 × (b - 1)

- The height of the wall is 1 1/8 (1.125) inches less than 4 feet

∵ 1 foot = 12 inches

∵ 4 feet = 12 × 4 = 48 inches

∴ The height of the wall = 48 - 1.125 = 46.875 inches

- The sum of the total height of bricks and the total height of mortar

 is equal to the height of the wall

∴ 2.25 b + 0.375(b - 1) = 46.875

- By simplify it

∴ 2.25 b + 0.375 b - 0.375 = 46.875

∴ 2.625 b - 0.375 = 46.875

- Add 0.375 for both sides

∴ 2.625 b = 47.25

- Divide both sides by 2.625

∴ b = 18

∴ 18 rows of bricks are needed

b)

* Lets complete the missing

- The total height of the bricks in inches is equal to 2.25 times b

- The total height of the mortar is equal to 0.375 times (b - 1)

-  Their sum is equal to the height of the wall or 46.875 inches

- If I write this as an equation and solve for​ b, then the result is

 18 rows of bricks

To find the number of rows of bricks needed for a wall, we can set up an equation to solve for that number. The equation will involve the heights of the bricks and mortar layers, as well as the height of the wall. Solving the equation will give us the number of rows of bricks needed.

To find the number of rows of bricks needed, we need to determine the total height of the bricks and the total height of the mortar. Let b be the number of rows of bricks. The total height of the bricks in inches is equal to the height of each brick multiplied by the number of rows (b). The total height of the mortar is equal to the height of the mortar layer multiplied by the number of rows minus 1 (b-1). The sum of the heights of the bricks and mortar is equal to the height of the wall, which is 4 feet minus 1/8 inches.

Writing this information as an equation, we have:

(height of the bricks x b) + (height of the mortar x (b-1)) = 4 feet - 1/8 inches

Solving this equation for b will give us the number of rows of bricks needed.

Hey!

-------------------------------------------------

Solution:

-5x + 15 = 35 - 10x

~Subtract 15 to both sides

-5x + 15 - 15 = 35 - 10x - 15

~Simplify

-5x = 20 - 10x

~Add 10x to both sides

-5x + 10x = 20 - 10x + 10x

~Simplify

5x = 20

~Divide 5 to both sides

5x/5 = 20/5

~Simplify

x = 4

Answer:24

Step-by-step explanation:

The ratio of 6 to 4 is the same as the ratio of 36 to 24. This is found by setting up the ratios as fractions, setting them equal to each other, and then solving for the unknown.

The question is asking for an equivalent ratio to that of 6 to 4, using 36 as the first term. To do this, you need to determine what number 36 is in the same ratio. A ratio is a relationship between two numbers indicating how many times the first number contains the second. In our case, 6 is to 4 as 36 is to what?

To find the answer, you can set up the ratios as fractions and solve for the unknown. For example, the ratio of 6 to 4 is expressed as 6/4. Because we want a ratio that's equivalent, we say 6/4 = 36/x, where x is the unknown number, we need to find.

Solving for x involves arranging the equation to isolate x and then performing the algebraic operation that gives the value of x. This would be: 6/4 = 36/x -> 6x = 36×4 -> 6x = 144 -> x = 144/6 -> x = 24.

Therefore, the ratio of 6 to 4 is equal to the ratio of 36 to 24 in math.

The functions f(x) = √16^x and g(x) = ∛64^x increase at the same rate as x increases.

The functions f(x) = √16ˣ and g(x) = ∛64ˣ are related in the way they grow or decrease as x increases. Let's analyze each function:

For the function f(x) = √16ˣ, as x increases, the value of f(x) also increases. This is because when x increases, 16^x becomes larger, and taking the square root of a larger number results in a larger value for f(x).

For the function g(x) = ∛64ˣ, the same logic applies. As x increases, the value of g(x) also increases. This is because when x increases, 64ˣ becomes larger, and taking the cube root of a larger number results in a larger value for g(x).

Therefore, both functions f(x) and g(x) increase at the same rate as x increases. None of the given options accurately describe the relationship between the graphs of f(x) and g(x).
