Starting with the sun,what energy transformations take place when cows graze in a meadow?

Heat and light energy gets transformed as energy for the plants to grow via the process of photosynthesis. The cows eat the grass, using the grass as an energy source to live and move around. Thus the grass, though indirectly, provides a means of kinetic energy that the cows use to move around and graze in the meadow.

Day and night kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Bark time hotel charges $30 per day plu

Sonbull [250]

The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total charges for for boarding a pet in x days.

Day and night kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Hence:

y = 20x + 15

Bark time hotel charges $30 per day plus a one-time food fee of $5. Hence:

y = 30x + 5

The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.

The vertices of square cdef are c(1, 1), d(3, 1), e(3,−1) and f(1,−1). Which of the following shows that its diagonals are congr

maks197457 [2]

The equation $-1 = -\frac {1}{1}$ shows that the diagonals are congruent perpendicular bisectors.

The vertices of the square are given as:

c = (1,1)
d = (3,1)
e =(3,-1)
f = (1,-1)

<h3>How to determine the congruent perpendicular bisectors.</h3>

Start by calculating the slope of diagonal ce using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{-1-1}{3 -1}$

$m = \frac{-2}{2}$

$m_1 = -1$

Next, calculate the slope of diagonal df using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{-1-1}{1-3}$

$m = \frac{-2}{-2}$

$m_2 = 1$

The slopes of both diagonals are:

$m_1 = -1$

$m_2 = 1$

By comparing both slopes, we have:

$m_1 = -\frac {1}{m_2}$

i.e.

$-1 = -\frac {1}{1}$

Hence, $-1 = -\frac {1}{1}$ shows that the diagonals are congruent perpendicular bisectors.
