GREYUIT [131]2 years ago
8 0

Answer:

The points are (-1, 1), (2, 7), (1, -1), (3, 0)

Step-by-step explanation:

Let us solve the question

∵ f(x) = y

∴ The coordinates of the point are (x, y)

→ Let us use this fact to find the coordinates of each point

∵ f(-1) = 1

∴ x = -1 and y = 1

∴ The coordinates of the point are (-1, 1)

∵ f(2) = 7

∴ x = 2 and y = 7

∴ The coordinates of the point are (2, 7)

∵ f(1) = -1

∴ x = 1 and y = -1

∴ The coordinates of the point are (1, -1)

∵ f(3) = 0

∴ x = 3 and y = 0

∴ The coordinates of the point are (3, 0)

mina [271]

Step-by-step explanation:

there is no mathematical problem to solve.

just follow the instructions as given.

this is an exercise for you to get a feeling about what is what. it is imperative that you do it.

there is really nothing to solve.

remember, that a positive slope means the line goes up (from left to right), and a negative slope means the line goes down (again from left to right).

and I am sure you know what vertical and horizontal means.

In order to finish the order on time the factory was supposed to produce 70 items daily. After hiring three more people they wer
maria [59]

Answer:

  40 days

Step-by-step explanation:

Let x represent the original production time. Then 70x is the order quantity involved.

When the same order quantity is produced at a rate of 80 items per day for x-5 days, we have the equation ...

  70x = 80(x -5)

  70x = 80x -400

  0 = 10x -400 . . . . . subtract 70x

  0 = x -40 . . . . . . . . divide by 10

  40 = x . . . . . . . . . . add 40

The original schedule was for production to take 40 days.

Find the volume of the triangular prism in the picture shown. Round your answer to the
Olenka [21]

Given:

A figure of a triangular prism.

Height of triangular base = 9\dfrac{2}{3} yd

Base of triangular base = 4 yd

Height of prism = 4 yd.

To find:

The volume of the triangular prism.

Solution:

Volume of a triangular prism is:

V=Bh              ...(i)

Where, B is the area of triangular base and h is the height of the prism.

Area of triangular base is:

B=\dfrac{1}{2}\times base\times height

B=\dfrac{1}{2}\times 4\times 9\dfrac{2}{3}

B=2\times \dfrac{29}{3}

B=\dfrac{58}{3}

Putting B=\dfrac{58}{3} and h=4 in (i), we get

V=\dfrac{58}{3}\times 4

V=\dfrac{232}{3}

V=77.33...

V\approx 77.3

The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.
