Answer:

4 right angles

Step-by-step explanation:

All rectangles have 4 right angles in common.

All the rectangles have all their right angles (there are four of them) in common. The bottom-left box correctly states the commanality.

A rectangle consists of 4 sides, connected end to end, such that all the adjacent sides are at right angles (90°) with each other.

Due to four corners in a rectangle, and all corners internally having right angles, so all the rectangles have 4 right angles in common.

It isn't necessary for all the four sides being equal (its for square though, a special case of rectangles). (we assume that the fourth box is stating that all 4 sides of all rectangles are same in length)

But all the rectangles have their oppositely faced side pairs having equal length within their pairs.

Also, even if all the rectangles have 4 sides, but one rectangle can have some other lengthed sides, and another rectangle can have its sides of other lengths.

Thus, all the rectangles have all their right angles (there are four of them) in common (well right angle is not the only thing they've got in common, like they've got exterior angles common, 4 vertices etc). The bottom-left box correctly states the commanality.

Answer:

  y = 20·2^x

Step-by-step explanation:

Use the given points to write two equations, then solve for 'a' and 'b'.

  20 = a·b^0 = a

  5120 = a·b^8 = 20·b^8   ⇒   256 = b^8

  b = 256^(1/8) = 2

Your function is ...

  y = 20·2^x

Answer:

Step-by-step explanation:

Complete the square:

y = x² + 12x + 27

  = x² + 2*6*x + 6² - 6² + 27

  = (x + 6)² - 36 + 27

  = (x + 6)² - 9

Answer:

Base - 7 yards

Height - 10 yards

Area - 35 square yards

Step-by-step explanation:

By definition, the base and height must be perpendicular. Technically, they are interchangeable, but base usually refers to the relative bottom of a figure.

The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is equal to [tex]A=\frac{1}{2}bh[/tex].

Therefore, we have:

[tex]A=\frac{1}{2}\cdot 7\cdot 10=\boxed{35\:\text{square yards}}[/tex]

Step-by-step explanation:

Side splitter theorem,

"If a line intersects two sides of a triangle and is parallel to the third side of the triangle, will divide the sides proportionally."

Therefore, ratio of the parts of two sides intersected will be proportional.

[tex]\frac{3}{15}= \frac{6}{x}[/tex]

[tex]x=\frac{6\times 15}{3}[/tex]

[tex]x=30[/tex]

Answer:

x=8

Step-by-step explanation:

9x - 8 = 64 (being vertically opposite angles)

9x = 64 + 8

x=72/9

x=8

9x -8

9*8 -8

72-8

64

The value of x will be equal to 8.

There are four angles created when two lines cross. There are two sets of non-adjacent angles among these angles. These are referred to as vertically opposite angles, opposite angles, or vertical angles. These angles are all of the same sizes.

The value of x will be calculated by equating the two opposite angles to each other.

9x - 8 = 64 (being vertically opposite angles)

9x = 64 + 8

x=72/9

Divide the number 72 by 9 to get the value of x.

x=8

Calculate the angle by putting the value of x.

Angle = 9x -8

Angle = 9x 8 -8

Angle = 72-8

Angle = 64

Therefore, the value of x will be equal to 8.

Answer:

Part 1)

The height of the diving board is 19 feet.

Part 2)

Five seconds.

Part 3)

44 feet.

Step-by-step explanation:

Joyce's dive is represented by the equation:

[tex]h=-t^2+10t+19[/tex]

Where h represents her height (in feet) after t seconds.

Part 1)

Joyce is on the diving board right before she jumps. Therefore, to find the height of the diving board, we can let t = 0, since this is before she had jumped. Hence:

[tex]h(0)=-(0)^2+10(0)+19=19\text{ feet}[/tex]

The height of the diving board is 19 feet.

Part 2)

Since this is a quadratic, the maximum height will occur at its vertex point.

So, we need to find the vertex. We can use the following formulas:

[tex]\displaystyle \text{Vertex}=\left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In this case, a = -1, b = 10, and c = 19.

So, the t-coordinate of the vertex is:

[tex]\displaystyle t=-\frac{(10)}{2(-1)}=5\text{ seconds}[/tex]

Joyce will reach her maximum height after five seconds.

Part 3)

To find the maximum height, simply substitute this value back into the equation. Hence:

[tex]h(5)=-(5)^2+10(5)+19=44\text{ feet}[/tex]

So, her maximum height is 44 feet in the air.
