Step-by-step explanation:

come on !

how do you create a line ?

you mark 2 points, take a ruler and draw a line through both points (and extend the line beyond the points as far as the chart goes).

how do you find points ?

you think about a nice value for x (really, any value on the x-axis of the chart is OK) and then calculate y.

you mark the point at this x, y coordinates.

you know, the x-axis is the horizontal coordinate line, and the y-axis is the vertical coordinate line.

so, I would pick x =0. that gives us y = 0 + 0.5 = 0.5.

and maybe x = 2. that gives us y = 2 + 0.5 = 2.5

so, you have (0, 0.5) and (2, 2.5) as points.

and then simply do as described above.

Answer:

Step-by-step explanation:

f(x) = x⁴ - 9x³ - 8x² - 9x - 2

f(-3) = (-3)⁴ -9*(-3)³ - 8*(-3)² - 9*(-3) - 2

       = 81 - 9*(-27) - 8*9  + 27 -2

       = 81 + 243 - 72 + 27 - 2

      = 277

Answer:

[tex]F(-3)=142[/tex]

Substitute x=-3 into

[tex]F(x)=x\times4-9x\times3-8x\times2-9x-2[/tex]

Substitute

[tex]F(-3)=-3\times4-9\times(-3)\times3-8\times(-3)\times2-9\times(-3)-2[/tex]

Determine the sign

[tex]F\left(-3\right)=-3\times4+9\times3\times3+8\times3\times2+9\times3-2[/tex]

Calculate the product or quotient

[tex]F(-3)=-12+9\times3\times3+8\times3\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+27\times3+8\times3\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+8\times3\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+24\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+48+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+48+27-2[/tex]

Calculate the sum or difference

[tex]F(-3)=69+48+27-2[/tex]

[tex]F(-3)=117+27-2\\F(-3)=144-2\\F(-3)=142[/tex]

We are given that the width of of a rectangular painting is 83 cm and it's area is 7719 cm² and we are asked to find it's length , as we know that the area of a rectangular shape is given by L×B. Where L is the length of the rectangular shape and B is the width/Breadth .Now , applying the same concept in our question we have ;

[tex]{:\implies \quad \sf L\times 83=7719}[/tex]

[tex]{:\implies \quad \sf L=\dfrac{7719}{83}}[/tex]

[tex]{:\implies \quad \sf L=93}[/tex]

Answer:

(-1.25,-0.25).

Step-by-step explanation:

The length of the rectangle is 2.5 units. To find the point that is 2.5 units from (1.25,1), count 2.5 units to the left of the point. The x-coordinate will change and the y-coordinate will remain the same. This point is (-1.25,1).

The width of the rectangle is 1.25 units. To find the point that is 1.25 units from (1.25,1), count 1.25 units down from the point. The y-coordinate will change and the x-coordinate will remain the same. This point is (1.25,-0.25).

For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.

In order to calculate the value of the P(z≤0.42), we need to check the value of 0.42 in the z-table, As the Z-table is already given and in the table, the value of z is 0.6628, therefore,

[tex]P(z\leq 0.42)\\\\=0.6628 \approx 66\\\\= 66\%[/tex]

Hence, For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.

Answer:

x^3 - 21x^2 + 144x - 324

Step-by-step explanation:

f(x) = x^2 - 15x + 54

g(x) = x - 6

To find f(x) x g(x), you just substitute the values of f(x) and multiply it with g(x).

(x^2-15x+54)(x-6) = x^3 - 15x^2 + 54x - 6x^2 + 90x - 324

                            = x^3 - 21x^2 + 144x - 324
