Applying the expression for speed, we found that the time taken for the bucket to hit the bottom of the well is 15 seconds

Given Data

Speed = 2 meters per second

Distance = 30 meters

Time = ??

We know that the expression for the relationship between speed, distance and time is given as

Speed = Distance/Time

substituting we have

2 = 30/t

cross  multiplying

2t = 30

divide both sides by 2

t = 30/2

t = 15 seconds

Answer 15 seconds

Answer:

Ratio of circumferences: [tex]\displaystyle\frac{1}{4}[/tex]

Ratio of radii: [tex]\displaystyle\frac{1}{4}[/tex]

Ratio of areas: [tex]\displaystyle\frac{1}{16}[/tex]

Step-by-step explanation:

Hi there!

We are given:

- The circumference of Circle K is [tex]\pi[/tex]

- The circumference of Circle L is [tex]4\pi[/tex]

Therefore, the ratio of their circumferences would be:

[tex]\displaystyle\frac{\pi}{4\pi}[/tex] ⇒ [tex]\displaystyle\frac{1}{4}[/tex] when simplified

The formula for circumference is [tex]C=2\pi r[/tex], where r is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.

If the circumference of Circle K is [tex]\pi[/tex], or [tex]1\pi[/tex], then its radius is [tex]\displaystyle\frac{1}{2}[/tex].

If the circumference of Circle L is [tex]4\pi[/tex], then its radius is [tex]\displaystyle\frac{4}{2}[/tex], which is 2.

Therefore the ratio their radii would be:

[tex]\displaystyle\frac{\frac{1}{2}}{{2}}[/tex] ⇒ [tex]\displaystyle\frac{1}{2}*\frac{1}{2}[/tex] ⇒ [tex]\displaystyle\frac{1}{4}[/tex] when simplified

The formula for area is:

[tex]A=\pi r^2[/tex]

First, let's find the area of Circle K:

[tex]A=\pi (\displaystyle\frac{1}{2})^2\\\\A=\displaystyle\frac{1}{4}\pi[/tex]

Now, let's find the area of Circle L:

[tex]A=\pi (2)^2\\A = 4\pi[/tex]

Therefore, the ratio of their areas would be:

[tex]\displaystyle\frac{\frac{1}{4}\pi}{4\pi}[/tex] ⇒ [tex]\displaystyle\frac{\frac{1}{4}}{4}[/tex] ⇒ [tex]\displaystyle\frac{1}{4} * \frac{1}{4}[/tex] ⇒ [tex]\displaystyle\frac{1}{16}[/tex] when simplified

Using linear functions, it is found that:

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

Paisley is 315 miles away from the stadium, and driving at a speed of 42 miles per hour, hence for the linear equation for his distance after t hours, we have that:

m = -42, b = 315, then:
P(t) = 315 - 42t.

Damian is 383 miles away from the stadium, and driving at a speed of 59 miles per hour, hence for the linear equation for his distance after t hours, we have that:

m = -59, b = 383, then:

D(t) = 383 - 59t.

After 5 hours, their distances are:

P(5) = 315 - 42(5) = 105

D(5) = 383 - 59(5) = 88

D(5) < P(G), hence Damian is closer to the stadium 5 hours after noon.

Answer:

The circle has an area of about 1385 square mm.

Step-by-step explanation:

Let's recall that circles have an area that can be found with the following formula:

[tex]A=\pi r^{2}[/tex]

where r is the radius of the circle.

Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.

[tex]A=\pi (21)^2\\A=441\pi \\A=1385.44236...[/tex]

So, to the nearest whole number, the area of the circle is 1385 square mm.

Answer:

b: 3/10 + 4/10 = 7/10

c:

Answer:

y = 2x

the formula for linear equations are y = mx+c,

where m is the gradient,

and c is the y-intercept

to find m (the gradient):

1. pick to points on the graph (eg. -2,-4 and 2,4)

2 substitute the values into the formula for gradient y2-y1/x2-x1.

m = y2-y1/x1-x2

= -4 -4/-2-2

= -8/-4

= 2

to find c (y-intercept):

- the y-intercept is where the graph cuts the y axis

- in this graph, the y-intercept is 0

hence,

c = 0

substitute m = 2 and c = 0 to y = mx+c,

y = 2x + 0

y = 2x

hence, the equation that best represents the relationship shown in the graph is y = 2x.
