Answer:

[tex]\displaystyle \frac{dx}{d\theta}=5\text{ ft/rad}[/tex]

Step-by-step explanation:

Please refer to the diagram below.

We can use the sine function. Recall that the sine function is the ratio between the opposite side and the hypotenuse. Hence:

[tex]\displaystyle \sin(\theta)=\frac{x}{10}[/tex]

We want to find how fast x changes with respect to θ. So, we want to find dx/dθ. Therefore, let's take the derivative of both sides with respect to θ:

[tex]\displaystyle \frac{d}{d\theta}[\sin(\theta)]=\frac{d}{d\theta}\left[\frac{1}{10}x\right][/tex]

Differentiate. Since it's with respect to θ, we can differentiate the left-hand side like normal. On the right, we will implicitly differentiate. This yields:

[tex]\displaystyle \cos(\theta)=\frac{1}{10}\frac{dx}{d\theta}[/tex]

Multiply both sides by 10. So, dx/dθ is:

[tex]\displaystyle \frac{dx}{d\theta}=10\cos(\theta)[/tex]

We want to find dx/dθ when θ is π/3. Thus, substitute π/3 for θ:

[tex]\displaystyle \frac{dx}{d\theta}=10\cos\left(\frac{\pi}{3}\right)[/tex]

Evaluate:

[tex]\displaystyle \frac{dx}{d\theta}=10\left(\frac{1}{2}\right)=5\text{ ft/rad}[/tex]

So, x is changing with respect to θ at a rate of 5 feet per radian.

Answer:

Larger number = 11

Smaller number = 6

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

x - y = 5

3y + 4 = 2x       Subtract 2x

-2x + 3y + 4 = 0

===========

Multiply  the first equation by 2. Write the second equation underneath

2x - 2y = 10

-2x + 3y + 4 = 0

add

y + 4 = 10  

Subtract from both sides

y = 10 - 4

y = 6

==========

x - y = 5

x - 6 = 5                Add 6 to both sides

x = 5 + 6

x = 11

Answer:

Step-by-step explanation:

x       ← the smaller number

x+5    ←  five more than the smaller number - the larger number

3x    ← three times the  smaller number

3x+4   ← four more than three times the  smaller number

2(x+5)   ← twice the larger number

3x + 4 = 2(x + 5)

3x + 4 = 2x + 10

   -4         -4

     3x = 2x + 6

  -2x       -2x

      x  =  6

x+5 = 6 + 5 = 11

Check:   3•6 + 4 = 22;  22:2 = 11

Can you specifiy?

Step-by-step explanation:

The average speed exceeding the speed limit is mathematically given as

6.91 kilometers per hour

This is further explained below.

Let's assume that Erik maintains a steady pace during the whole trip.

Therefore, the following equation of motion may be used to compute the speed, which is expressed in terms of miles per hour:

Where: miles is the unit of measurement for distance.

t stands for time, which is measured in hours.

Kindly take into account that one hour is comprised of sixty minutes. If we assume so, then we can calculate Erik's speed as follows:

[tex]\begin{aligned}&v=\frac{19.2 m i}{0.267 h} \\\\&v=71.910 \frac{m i}{h}\end{aligned}[/tex]

In conclusion, That is 6.91 kilometers per hour faster than the allowed speed limit.

Answer:

-4 =x

Step-by-step explanation:

2x - 5= 5x + 7

Subtract 2x from each side

2x-2x - 5= 5x-2x + 7

-5 = 3x+7

Subtract 7 from each side

-5-7 = 3x+7-7

-12 = 3x

Divide by 3

-12/3 = 3x/3

-4 =x

Answer:8 Dollars

Step-by-step explanation: The whole is 100 so you add 50 and 10 together which is the lunch and candy which equals 60 then you subtract the whole number 100 by 60 giving you 40 which is the percentage of 20 that was spent on the spirit shirt.And the way I do it is 10 percent of 20 is 2 so times 2 by 4 which gives you 8 dollars.

Answer:

16 songs.

Step-by-step explanation:

If Aaliyah has 50 songs, but her phone can only hold a third of those songs, to solve this problem, we will have to find a third of 50.

Divide 50 into 3:

[tex]50[/tex] ÷ [tex]3[/tex]

[tex]=16.6666...[/tex]

As this decimal does not terminate, we'll have to round down to [tex]16[/tex] since we cannot have a portion of the song downloaded.

Therefore, Aaliyah can download 16 songs on her phone.

264.6

Step-by-step explanation:

ok first of all if you are subtracting a negative the it becomes a positive

136 - (-128.6)

136 + 128.6

this is what goes on in my head you don't have to do it this way but i do

100 + 100 = 200

30 + 20 = 50

6 + 8.6 = 14.6

200 + 50 + 14.6 = 264.6

Answer:

The correct option is;

y = arcsinx and y = arctanx

Step-by-step explanation:

The given options are;

1) y = arcsinx and y = arccosx

Here, we have at the origin, where x = 0,  arccosx ≈ 1.57 while arcsinx = 0

Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin

2)  y = arccosxy and y = arctanx

Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical

3) y = arctanx and y = arccotx

Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical

4) y = arcsinx and y = arctanx

Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.

The function are symmetric with respect to the origin is y = arcsinx and y = arctanx and this can be determined by using the trigonometric property.

The following steps can be used in order to determine which functions are symmetric with respect to the origin:

Step 1 - Check all the options given in order to determine which functions are symmetric with respect to the origin.

Step 2 - Substitute (x = 0) in option a), that is:

[tex]\rm y = sin^{-1}(0)=0[/tex]

[tex]\rm y = cos^{-1}(0)=1.57[/tex]

Step 3 - Substitute (x = 0) in option b), that is:

[tex]\rm y = cos^{-1}(0)=1.57[/tex]

[tex]\rm y = tan^{-1}(0)=0[/tex]

Step 4 - Substitute (x = 0) in option c), that is:

[tex]\rm y = tan^{-1}(0)=0[/tex]

[tex]\rm y = cot^{-1}(0)=1.57[/tex]

Step 5 - Substitute (x = 0) in option d), that is:

[tex]\rm y = tan^{-1}(0)=0[/tex]

[tex]\rm y = sin^{-1}(0)=0[/tex]

A = 2044 sqcm; P = 221 cm (PLEASE DOUBLE CHECK CALCULATIONS!!)

Step-by-step explanation:

the area of a triangle is half of its base times height.

the base and the height must be perpendicular to each other; so they would be 56 and 73.

56(73)/2=2044

the perimeter is the sum of all the sides

73+56+92=221

The area of the right-angled triangle is 2044 cm² and the perimeter of the right-angled triangle is 221 cm.

To find the area and perimeter of a right-angled triangle with dimensions 73 cm, 92 cm, and 56 cm.

Area of a right-angled triangle:

The area of a triangle can be found using the formula:

A = (1/2) x base x height

Plugging these values into the formula, we get:

A = (1/2) x 73 cm x 56 cm

A = 2044 cm²

Therefore, the area of the right-angled triangle is 2044 cm².

Perimeter of a right-angled triangle:

The perimeter of a triangle is the sum of all its sides.

In this case, the sides of the triangle are 73 cm, 92 cm, and 56 cm.

Perimeter = 73 cm + 92 cm + 56 cm

Perimeter = 221 cm

Therefore, the perimeter of the right-angled triangle is 221 cm.
