can I have detailed explanation please ​

If she paddles directly to Kono's then the minimum time for the lunch will be 3.9 hours.

It is the study of the motion of a body without considering mass. And the reason behind them is neglected.

Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak.

Hunger strikes and she wants to make it to Kono's for lunch; see picture.

Brooke can paddle at 7 mph and walk at 14 mph.

Distance from Brooke to shore will be

→ √(5² + x²)

Then the time will be

[tex]t_1 = \dfrac{\sqrt{5^2 + x^2}}{2}[/tex]

Then the distance from shore to Kono's will be

→ 6 - x

Then the time will be

t₂ = (6 - x) / 4

Then the total time will be

t  = t₁ + t₂

Then we have

[tex]t = \dfrac{\sqrt{5^2 +X^2}}{2} + \dfrac{6-x}{4}\\[/tex]

t = 1/4[2√(5² + x²) + 6 - x]

If she paddles directly to point A will be

t = 1/4[2√(5² + 0²) + 6 - 0]

t = 1/4 (10 + 6)

t = 16 /4

t = 4 hr

If she paddles directly to Kono's, then we have x = 6. Then the time will be

t = 1/4[2√(5² + 6²) + 6 - 6]

t = 1/4[2√61]

t = 3.9 hr

Answer:

5.236 units

Step-by-step explanation:

The relation between r, θ and arc length ( l ) is,

l = rθ

l = 1 * 5π / 3

( The value of π = 3.14 approximately )

5π = 5 x 3.14 = 15.7

l = 1 * 5π / 3

= 5π / 3

= 15.7/3

l = 5.236 units

Note : -

Arc length is denoted by " l ".

Answer:

x^2 + y^2 = 9

Step-by-step explanation:

The equation of a circle is (x^2) -a)^2 + (x^2) - b)^2 = r^2, where a and b are the center of the circle. Because the center of the circle is (0,0), it'll just be x^2+y^2 for one half of the equation. If the circle passes through (-3,0), that would mean the radius of the circle is 3. r^2 is 3^2, which is 9, so the equation of the circle is x^2 + y^2=9. Hope this helps!

The equation of the circle is x² + y² = 9

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the point be represented as A ( -3 , 0 )

Now , the center of the circle = O ( 0 , 0 )

And , standard form of a circle is

( x - h )² + ( y - k )² = r²

where In this case, we know that the circle passes through the point (-3, 0) and is centered at the origin (0, 0). Therefore, the radius of the circle is the distance from the origin to (-3, 0), which is:

r = √((-3 - 0)² + (0 - 0)²) = √(9)

r = 3 units

So the equation of the circle in standard form is:

(x - 0)² + (y - 0)² = 3²

On simplifying , we get

x² + y² = 9

Hence , the equation in standard form for the circle passing through (-3,0) centered at the origin is x² + y² = 9

Answer:

156.32 joules 

Step-by-step explanation:

In this case, we know the force of 64 N and the distance of 3 m. We also know that there is a 120°angle between the angle of the direction of applied force and the direction of motion. So plugging these values into our handy equation yields:

W = 64(3)cos(120)= 156.32 Joules

So the 64 N force at a 120° angle did 156.32 joules of work moving the book 3 meters.

Using proportions, it is found that the coordinates of point C are given as follows: C(-7, -2).

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Point C divides the line segment OP into the ratio 3:5, hence the following equation is used to relate the points:

[tex]C - O = \frac{3}{8}(P - O)[/tex]

Then, for the x-coordinate:

[tex]x + 10 = \frac{3}{8}(-2 + 10)[/tex]

x + 10 = 3

x = -7

For the y-coordinate:

[tex]y + 8 = \frac{3}{8}(8 + 8)[/tex]

y + 8 = 6

y = -2

The coordinates of point C are given as follows: C(-7, -2).

Answer:

128 cubes can fit in.

Step-by-step explanation:

We are given: Volume of rectangular prism = 2 units³ and Cube with edge = 1/4 unit

We must find: The number of cubes that can fill the prism

Firstly, find the volume of 1 cube:

Volume = 1/4 x 1/4 x 1/4

Volume = 1/64 units³

Next find the number of cubes that can go into the prism:

Number of cubes = 2 ÷ 1/64

Number of cubes = 128

Therefore 128 cubes can fit in.
