An office building has 123 floors. The floors are 3.8m apart.
A lift goes from floor 32 to the top. How far does it travel?​

Answer:

Area = 88 units squared

Perimeter = 40 units

Step-by-step explanation:

The formula for the Area of the parallelogram is base (11) times height (8)

The perimeter is just adding all the outsides together (11 + 11 + 9 + 9)

Answer:

Nothing for can be done with it!

what is the coordinate of the vertex for the following parabola:

-8 ( x - 5 ) = ( y + 1 ) ² (5, -1)

what is the coordinate of the focus for the following parabola:

-8 ( x - 5 ) = ( y + 1 ) ² (3, -1)

The vertex of the equation of a parabola [tex]- 8 (x - 5) = (y + 1)^2[/tex] by compared with the standard form of the equation of a parabola [tex]x = a (y - k)^2 + h[/tex] is,

⇒ (h, k) = (5, - 1)

Where, [tex](h, k)[/tex] is the vertex of the parabola.

We have to give that,

The equation of a parabola is,

[tex]- 8 (x - 5) = (y + 1)^2[/tex]

The standard form of the equation of a parabola is,

[tex]x = a (y - k)^2 + h[/tex]

Where, [tex](h, k)[/tex] is the vertex of the parabola.

Here, The equation of a parabola is,

[tex]- 8 (x - 5) = (y + 1)^2[/tex]

It can be written as,

[tex](x - 5) = \frac{(y + 1)^2}{-8}[/tex]

Add 5 on both sides,

[tex]x = \frac{(y + 1)^2}{-8} + 5[/tex]

Now, compare with the standard form of the equation of a parabola,

h = 5

k = - 1

Therefore, the vertex of the parabola is, (5, - 1).

Step-by-step explanation:

Because learning about stingrays asking a question like that can tell you how many are left and how long you have to study them while they are here. and A because you wanna get to know their surroundings and what's better for them in an environment before you actually get to know about the stingrays, studying the environment can give you an idea of what to look for when you are diving in the ocean. Meaning you know exactly what to look for when diving so you can get as much information as you need.

Answer:

It's a rectangle, but not a rhombus (or square).

Step-by-step explanation:

Let's see the vectors of each next vertex:

[tex]Q - P = (4, 5) - (-5, 2) = (9, 3)\\R - Q = (6, -1) - (4, 5) = (2, -6)\\S - R = (-3, -4) - (6, -1) = (-9, -3)\\P - S = (-5, 2) - (-3, -4) = (-2, 6)\\[/tex]

Firstly, we can notice that it's a parallelogram - because the Q-P side is parallel to the S - R side (if the x:y ratios are the same, the sides are parallel).

A rhombus needs the sides to be of the same length. But the length of a (x, y) vector is [tex]\sqrt{x^2 + y^2}[/tex] and [tex]\sqrt{9^2 + 3^2} > \sqrt{2^2 + (-6)^2}[/tex], we don't even have to compute it exactly. If it's not a rhombus, it's also not a square (every square is a rhombus).

The last thing left is to know if it's a rectangle - for it to be a rectangle, we need to check if the vectors are perpendicular.

We can compute the dot product of the vectors - perpendicular vectors always have a dot product equal to zero. The dot product of two vectors [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is equal to [tex]x_1x_2 + y_1y_2[/tex].

[tex](9, 3) \cdot (2, -6) = 9\cdot 2 + 3\cdot(-6) = 18 - 18 = 0[/tex]

So the sides are perpendicular, and as such - the figure is a rectangle.

Answer:

Statement B and statement D are true

Step-by-step explanation:

A game has green and blue pieces. The ratio of

green game pieces to total pieces is 5:12.

Select all the statements that are correct about the game pieces.

A. The ratio of green pieces to blue pieces is 7:5.

B. The ratio of total pieces to blue pieces is 12:7,

C. There must be 7 more blue pieces than green pieces.

D. The ratio of total pieces to green pieces is 12:5.

Ratio of green pieces = 5

Ratio of total pieces = 12

Ratio of blue pieces = Ratio of total pieces - Ratio of green pieces

= 12 - 5

= 7

Ratio of blue pieces = 7

A. The ratio of green pieces to blue pieces is 7:5.

Green pieces : blue pieces = 5 : 7

A is not true

B. The ratio of total pieces to blue pieces is 12:7

Total pieces : blue pieces = 12 : 7

B is true

C. There must be 7 more blue pieces than green pieces.

Blue = 7

Green = 5

There are 2 more blue pieces than green pieces

C is not true

D. The ratio of total pieces to green pieces is 12:5

Total pieces : green pieces = 12 : 5

D is true

Option (3)

Step-by-step explanation:

By the theorem, angle between two tangents intersecting each other outside the circle is half of the difference between intercepted arcs.

From the figure attached,

Two tangents CD and DE are intersecting each other at point D outside the circle A.

Two intercepted arcs are minor arc CE and major arc CBE,

Measure of arc CE = 112°

Therefore, measure of major arc CBE = 360° - 112°

                                                               = 248°

m(∠CDE) = [tex]\frac{1}{2}(\text{arcCBE}-\text{arcCE})[/tex]

                 = [tex]\frac{1}{2}(248-112)[/tex]

                 = [tex]\frac{1}{2}\times 136[/tex]

                 = 68°

Option (3) will be the correct option.

The answer that is not true when x = -4 is B.

Step-by-step explanation:

Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.

A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.

Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.

Finally D. -4/4 divided equals -1, so that would make it -1 = -1.

B is the only one that doesn't make sense, therefore you have your answer.

5/6+1/15+1/12in on minute

Emma's best record is 59/60 kilometers per minute.

Given that, Emma personal record was 5/6 of a kilometer in one minute.

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.

Now, 5/6 + 1/15 + 1/12

LCM of denominators 6, 15 and 12 is 60.

50/60 + 4/60 + 5/60

= 59/60

Therefore, Emma's best record is 59/60 kilometers per minute.

The slope of the line as shown in the graph of the linear function in the image below is: negative.

The slope of a line of a linear function = change in y/change in x.

The value of the slope would be positive if the graph increases upwards from your left to your right.

The value of the slope would be negative if the graph decreases downwards from your left to your right.

Thus, the slope of horizontal lines are always zero while the slope of vertical lines are undefined.

Therefore, the slope of the line as shown in the graph of the linear function in the image below is: negative.
