Answers

-4 is the y-intercept. The y-intercept can be found when the line passes the y-axis, in this case it is -4.
The y axis is the line going vertically so it would be -4.

Which graph represents a linear function? (4 points)

Answers

Answer:

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?

That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

Answer:

SA = 74.4 square yards

V = 32.7 cubic yards

Step-by-step explanation:

formula for SA for square pyramid: Area of Base + Area of 4 Triangles

SA = 3² + 4[(3 x 10.9) ÷ 2]

    = 9 + 4(16.35)

    = 9 + 65.4

formula for Volume for square pyramid: 1/3 · Area of Base · Height

V = 1/3 · 9 · 10.9

   = 3 × 10.9

In a village, there are houses, flats and bungalows in the ratio
14:8:5. There are 50 bungalows in the village.
How many places are there to live in the village?

Answers

Answer:

270

Step-by-step explanation:

Given that :

Ratio = 14:8:5

Houses : flats : bungalow

Number of bungalow = 50

Sum of ratio = (14 + 8 + 5) = 27

Let total number of households = x

Bungalow = 5/27 * x

5/27 * x = 50

5x / 27 = 50

5x = 50 * 27

5x = 1350

x = 1350 / 5

x = 270

Number of places to live = 270

Find all the zeros for the following function y=x2 - 6x +16x-96 The zeros are​

Answers

Answer:

The zeros for the function

[tex]x=6,\:x=4i,\:x=-4i[/tex]

Step-by-step explanation:

Given the expression

[tex]y=x^3-6x^2+16x-96[/tex]

Plug in y = 0 to determine all the zeros

[tex]x^3-6x^2+16x-96=0[/tex]

as

[tex]x^3-6x^2+16x-96=\left(x-6\right)\left(x^2+16\right)[/tex]

so the expression becomes

[tex]\left(x-6\right)\left(x^2+16\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]x-6=0\quad \mathrm{or}\quad \:x^2+16=0[/tex]

solving

[tex]x-6=0[/tex]

[tex]x = 6[/tex]

solving

[tex]x^2+16=0[/tex]

subtract 16 from both sides

[tex]x^2+16-16=0-16[/tex]

[tex]x^2=-16[/tex]

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

[tex]x=\sqrt{-16},\:x=-\sqrt{-16}[/tex]

as

[tex]x=\sqrt{-16}[/tex]

[tex]\sqrt{-16}=\sqrt{-1}\sqrt{16}[/tex]

as

[tex]\sqrt{-1}=i[/tex]

so

[tex]x=4i[/tex]

and

[tex]x=-\sqrt{-16}[/tex]

[tex]-\sqrt{-16}=-\sqrt{-1}\sqrt{16}[/tex]

as

[tex]\sqrt{-1}=i[/tex]

so

[tex]x=-4i[/tex]

Thus, the zeros for the function

[tex]x=6,\:x=4i,\:x=-4i[/tex]
