A function in mathematics is a relation between two sets such that each element of the first set is matched to exactly one of the second set element

The correct option for the maximum velocity of the object is the option;

13 cm/s

The reason for the selection is as follows:

The known parameters of the motion of the vehicle are:

The type motion of the vehicle = Repetitive back and forth

The path of the motion of the object = Along a straight line

The function that gives the velocity in centimeters per second (cm/s) is given as follows;

[tex]v(t) = \mathbf{13 \cdot sin \left(\dfrac{\pi}{45} \cdot t \right)}[/tex]

Where;

t = The time in seconds (a set of the input variables of the function)

v(t) = The velocity of the object (the output variables of the function)

The velocity of the object, v(t), depends (is given by) on the time t, therefore;

The maximum velocity is given at a particular value of t, which together with [tex]\dfrac{\pi}{45}[/tex] is operated by the sine function

The maximum output value of the sine function = 1, therefore;

[tex]\mathbf{Maximum \ value \ of \ sin \left(\dfrac{\pi}{45} \cdot t \right)_{max}} = 1[/tex]

[tex]The \ maximum \ velocity \ v(t)_{max}} = 13 \times sin \left(\dfrac{\pi}{45} \cdot t \right)_{max} = 13 \times 1 = \mathbf{ 13}[/tex]

The units of the of the function is cm/s

Therefore, the maximum velocity of the object is 13 cm/s

Answer:

Step-by-step explanation:

There is a possible issue in your question...

As written it can be interpreted in two ways

like this #1 :

 [tex]5^{2x} = 3(2^x)[/tex]

or like this #2 :

  [tex]5^2x = 3(2^x)[/tex]

VERSION #1

divide by the 2^x

[tex]\frac{5^{2x} }{2^x} = 3[/tex]

to be able to get to the exponent you have to take "logs"

... look up the rules for logs ... log(ab) = log (a)+log(b) , log(a/b) = log(a)-log(b) etc.

if you take the logs of both sides the using the quotient rule and the exponent rule ....result the result is...

[tex]5^{2x}=3\left(2^x\right)\quad :\quad x=\frac{\ln \left(3\right)}{2\ln \left(5\right)-\ln \left(2\right)}\quad \left(\mathrm{Decimal}:\quad x=0.43496\dots \right)[/tex]

VERSION #2

[tex]5^2x\:=\:3\left(2^x\right)[/tex]

25 x = 3(2^x)

[tex]\frac{25}{3} = \frac{2^{x} }{x}[/tex]

This gets really nasty, and I assume that it is not the original problem..

[tex]x=-\frac{\text{W}_{-1}\left(-\frac{3\ln \left(2\right)}{25}\right)}{\ln \left(2\right)},\:x=-\frac{\text{W}_0\left(-\frac{3\ln \left(2\right)}{25}\right)}{\ln \left(2\right)}\quad \mathrm{ }:\quad x=5.52482 ,\:x=0.13144[/tex]

Answer:

Step-by-step explanation:

(2n³ - 3n⁴ + 7n) - (n³ - 8n⁴ - 7n) = 2n³ - 3n⁴ + 7n - n³ + 8n⁴ + 7n

  {Here -1 is distributed }

                                                  = 2n³ - n³ - 3n⁴ + 8n⁴ + 7n + 7n

                   {Combine like terms}

Answer:

4/5

Step-by-step explanation:

What a unique handwriting you have there. Anyways for this types of questions you just have to imagine a right-angled triangle and write down the values and an angle (2A).

First, to find height of the triangle, you can try using Pythagorean theorem, √(5²-3²) and you'll get the value 4.

Remember the formula,

sin a = opposite/hypothenuse.

Substitute the values in,

sin 2A = 4/5

Answer:

Option 3

Step-by-step explanation:

If he burned off 400 calories from 1500 consumed calories, he has 1100 consumed calories.  1900 - 1100 = 800 calories left to consume.

While option 2 also says no, it's not the right reason.  

The calories left to consume for the day is 800 calories.

No, 1,100 will cause him to exceed 1,900.

Given,

Jace has consumed 1,500 calories so far today.

He has also burned off 400 calories at the gym.

He would like to keep his daily calorie total to 1,900 calories per day.

We need to find how many calories he has left to consume for the day.

And see which option is the best choice.

We have,

Calories consumed in a day = 1500

Burned calories = 400

Calories to keep in a day = 1900

Find the Calories left

= 1500 - 400

= 1100

Find how many calories need to be consumed to keep 1900 calories.

= Calories needed to keep in a day - calories remaining after burned

= 1900 - 1100

= 800

We see that the calories left to consume is 800 calories.

So 1100 is not a viable solution. It will cause him to exceed 1,900.

Thus,

The calories left to consume for the day is 800 calories.

No, 1,100 will cause him to exceed 1,900.

#SPJ2

Answer:  72 degrees, if I read the question correctly.

Step-by-step explanation:  The sum of all the angles in a complete circle is 360 degrees.  Angles oppor=site each other are equal, so we have two angles of 95 degrees each, for a total of 190.  That leaves 170 for the other two angles, which are also equal,  So they must 85 each.  If I read the diagram correctly, it assigned this angle equal to d + 13,  I have no clue why, but if so:

 d + 13 = 85

 d = 72 degrees

Answer:

60π in²

Step-by-step explanation:

Inner Circle:

r = 2 in

Area of inner circle = πr²

        = π* 2 * 2

       = 4π   in²

Middle circle:

r = 6 + 2 = 8 in

Area of middle circle = π * 8 * 8

                                    = 64π in²

Area of shaded region =  area of middle circle -area of inner circle

                                       = 64π - 4π

                                       = 60π in²

Answer:

A = 60pi

Step-by-step explanation:

the radius of the smallest circle is 2 inches so that would give us an area of 4pi. the distance in the shaded part is 6 inches, since we're wanting to find the area of the shaded part, we'll add the radius of the smallest circle, 2 inches, and add it to the length of the shaded circle, 6 inches, to get a radius of 8 inches. plug 8 inches into the formula and youll get 64pi then subtract the 4pi from 64pi and youll get 60pi, which is the area of the shaded part of a circle.
