Answer:

"so i need to find e missing side of each right triangle, side c is the hypotenuse!! a = 8.8ft, b= 9ft i have to round the answers to the nearest tenth if necessary "

Step-by-step explanation:

Sure! So remember that the Pythagorean theorem is a squared plus b squared = c squared.

= 8.8 squared + 9 squared = c squared

= 77.44 + 81 = c squared

[tex]\sqrt{158.44}[/tex] = c squared

c squared = (rounded) 12.6 ft

–80, –110

Step-by-step explanation:

-80 and -110

It is an arithmetic sequence. The difference = -30. It is the difference between each number in the sequence: 10-40=-30

-50-30=-80

-80-30 =-110

-80

First Identify the sequence being made here.

10-40 = -30

-20-10 = -30

-50-(-20) = -30

Therefor this pattern is decreasing by a rate of 30 so to continue this, just subtract 30 from -50.

-50-30 = -80

The next term is -80.

Is it possible to have a line segment with: [tex]m = \infty[/tex]

To answer this question, we will interpret the steepness as slope.

So, we have:

[tex]m = \infty[/tex]

The interpretation of a line with: [tex]m = \infty[/tex] is:

It starts from (x,y_1) and ends at (x,y_2)

When the slope (m) is then calculated, we have:

[tex]m = \frac{y_2 - y_1}{x_1 - x_1}[/tex]

[tex]m = \frac{y_2 - y_1}{0}[/tex]

[tex]m = \infty[/tex]

What this means is that, the line has no end points.

A line segment as described here means a line that has endpoints (i.e. a finite starting point and a finite finish point)

So, we've established that: [tex]m = \infty[/tex] means no endpoints and a line segment has end points, then we can conclude that it is not possible to create a line segment with [tex]m = \infty[/tex]

Steepness of a  line is the rise or fall of it at a sharp angle.The Is it not possible to create a line segment with infinite steepness, as the slope of the such line will be infinite whether a line is plotted with finite points.

Steepness of a  line is the rise or fall of it at a sharp angle. The slope of the line describe the steepness of a line.

A infinite steepness refers to a vertical line on the graph. When the line with infinite steepness plotted on the graph it is only parallel to the y axis. The change on the x axis is zero and does not move in the x axis, when a line has infinite steepness.

To understand it better suppose a line is passed through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] points. For such line the slope of the line can be given as,

[tex]m=\dfrac{y_2-y_1}{x_2-x_1} [/tex]

The line with infinite steepness does not move in the x axis. The coordinate of the x axis same for the line. Thus,

[tex]x_2=x_1[/tex]

The slope for such line is,

[tex]m=\dfrac{y_2-y_1}{x_1-x_1} [/tex]

[tex]m=\dfrac{y_2-y_1}{0} [/tex]

[tex]m=\infty[/tex]

Thus the slope of the line is infinite. But the line With no finite point is not possible to plot.

Hence the Is it not possible to create a line segment with "infinite steepness, as the slope of the such line will be infinite whether a line is plotted with finite points.

Answer:

y = 1/4 (x-4)² - 7

Step-by-step explanation:

Point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

√(x-4)²+(y- -8)² = √(y- -6)²

(x-4)² + (y+8)² = (y+6)²

(y+8)² - (y+6)² = (x-4)²

(y²+16y+64) - (y²+12y+36) = (x-4)²

y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

4y = (x-4)² - 28

y = 1/4 (x-4)² - 7

standard formula of parabola: y = a(x-h)² + k      (h,k): vertex (4,-7)

The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.

Now,

Let a point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

Hence, We can formulate;

⇒ √(x-4)²+(y- (-8))² = √(y- (-6))²

⇒ (x-4)² + (y+8)² = (y+6)²

⇒ (y+8)² - (y+6)² = (x-4)²

⇒ (y²+16y+64) - (y²+12y+36) = (x-4)²

⇒ y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

⇒ 4y = (x-4)² - 28

⇒ y = 1/4 (x-4)² - 7

Thus, The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

Answer is A 520mm²

I hope you like it

Answer:

9. C, II and III.

10. The correct answer is 944 cubic mm, as far as I can tell. I double checked my formulas and calculations. You can copy the formulas/calculations below and email your teacher. I have tried to figure out how they got the numbers they have. The best guess I can come up with is that they used 6 as the diameter of the cylinder, using 3 for the radius. That gets us closer, at 749 cubic mm, but not quite there.

Step-by-step explanation:

9.  If the cylinder is standing upright, the horizontal cut would be a circle or oval, and the vertical cut could be a rectangle

10. First we'll get the volume of the base rectangle. Then we'll calculate the volume of a cylinder, then divide that part in half, because it's 1/2 a cylinder on top of a rectangular prism.

Volume of a rectangular prism:

V = (length)(width)(height)

= 11 x 9 x 6 = 594 cubic mm

Volume of a cylinder:

V = (pi)(radius)^2(height)

The radius = 1/2 the diameter of the circle...the diameter is 9, so the radius is 4.5

= (3.14)(4.5)(4.5)(11)

= 699.435

That would be for a full cylinder with radius 4.5 and height of 11. We have half of one, so 699.435/2 = 349.7175 cubic mm

Add the volume of the 1/2 cylinder to the volume of the rectangular prism:

349.7175 + 594 = 943.7175, rounded = 944...which is none of your answers :/

Sorry I couldn't give you an "A, B, C, D" answer, but I don't think any of those are correct.

Step-by-step explanation:

The dilation about the origin is straightforward, you just multiply the coordinates of each point by the scale factor.

so the dilated point for (-4,-4) is -4x3.5= -14 which is the same for the y coordinate.

so the dilated point for (-4,-4) is (-14, -14)
