The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour. If
the depth after 6 hours of draining is 8 feet then write an equation for the water depth, d, as a function of the
amount of time it's been draining, t, in hours.

Answers

The linear function for the depth of water after t hours is given by:

[tex]d(t) = 17 - 1.5t[/tex]

The format of a linear function is given as follows:

[tex]d(t) = d(0) - at[/tex]

In which:

d(0) is the y-intercept, which is the initial value.a is the slope, which is the rate of change.

The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour, which means that [tex]a = -1.75[/tex], thus:

[tex]d(t) = d(0) - 1.5t[/tex]

The depth after 6 hours of draining is 8 feet, which means that when [tex]t = 6, d(t) = 8[/tex]. This is used to find d(0).

[tex]d(t) = d(0) - 1.5t[/tex]

[tex]8 = d(0) - 1.5(6)[/tex]

[tex]d(0) = 17[/tex]

Then

[tex]d(t) = 17 - 1.5t[/tex]

Graph by using the slope and the y intercept.

Answers

1. a) equation of the line :

[tex]y = \dfrac{2}{5}x - 7[/tex]

y - intercept = -7

so, it will pass through point (0, -7)

and if we plug the value of x as 5, we get

[tex]y = (\dfrac{2}{5} \times 5) - 7[/tex]

[tex]y = 2 - 7[/tex]

[tex] = - 5[/tex]

so, it will pass through point (5, -5) too

now, just plot the points (0 , -7) and (5 , -5) and join them.

2. b) equation of line is :

[tex]y = - 3x + 5[/tex]

here, y - intercept = 5

so the line passes through point (0 , 5)

now, Plugging the value of x = 1 we get :

[tex]y =( - 3 \times 1) + 5[/tex]

[tex]y = - 3 + 5[/tex]

[tex]y = 2[/tex]

so, the given line passes through point (1 , 2)

plotting the points, we can get our required line.

hope this answer helps you dear...

Hi !
A
19 + 7 / 2 - 5
According to PEMDAS, division comes first, so we start by diving 7 by 2, which equals 3.5.
19 + 3.5 - 5 = 17.5

B
19 + 7 / 2 - 5
In order for this to equal 8, the brackets will be placed like this: (19 + 7)/2 - 5
It gives (26)/2 - 5
Then we divide 26 by 2 (according to PEMDAS once again)
We get 13 - 5 = 8

C
19 + 7 / 2 x 6 + 1
In order to get 2 as an answer, we place the brackets this way:
(19 + 7)/(2 x 6 + 1)
(26)/(12 + 1)
26/13 = 2

The length of a rectangular sign is 5 times its width. If the sign’s perimeter is 24 inches, what is the sign’s area The sign's area is ___ square inches.

Answers

The sign's area is 80 square inches.

A rectangle is a quadrilateral. This means that a rectangle has four sides.

The area of a rectangle = length x width

Perimeter of a rectangle = 2 x ( length + width)

Let the width of the sign be represented with w

The length of the sign is 5x

Substitute these dimensions into the formula for the perimeter of a rectangle.

(x + 5x) = 24

6x = 24

x = 24/6

x = 4 inches

The length is 5 x 4 = 20 inches

Area of the sign = 20 x 4 = 80 inches²

temperature had dropped 14°C.

Answers

-24 Celsius that is the answer

Answer:

By sunset the temperature was -24

Step-by-step explanation:

The reason for this is you start off with -10, then the word dropping relates to subtraction, meaning that the equation is -10-14, and when you subtract a negative, you are actually adding to it, so you can drop the negative for now, and you have 10+14 which equals 24, then add the sign back in to get -24C.

Line L and m are prendicular with point of intersection P. Noah says that a 180 degree rotation with center p has the same effects on points in the plane as reflecting over line m. Do you agree with Noah? Explain your reasoning

Answers

The point of intersection is the point where two or more lines meet.

Noah's claim is incorrect

The given parameters are:

Line l, line m and point of intersection p

See attachment for illustration of the perpendicular lines l and m.

Figure 1 represents the original lineFigure 2 represents the line rotated 180 degreesFigure 3 represents the line reflected over line m

Using the attachment as a guide, we can see that both transformations do not have the same effect on the points on both lines.

This is so because, figures 2 and 3 can be transformed to one another by reflecting across line l.

Hence, Noah's claim is incorrect
