Answer:

A trapezoid has no axes of reflectional symmetry. A trapezoid has no rotational symmetry (Order 1). Note: Having no rotational symmetry means that the figure must be rotated a full 360º to again appear in it original position.

Firdavs [7]

Answer:

5 35/72 kilometers

Step-by-step explanation:

The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode

This is calculated as:

Total distance = 6 7/12 km

Evan rode = 5/6 of the distance

Hence:

The distance Evans rode is

5/6 of 6 7/12

= 5/6 × 79/12

= 395/72

= 5 35/72 km(kilometers)

The graph of f(x)=sin(x) is transformed to a new function, g(x) , by stretching it vertically by a factor of 2 and shifting it 3

Leona [35]

Answer:

$g(x)=2sinx+3$

Step-by-step explanation:

The sine function has the general equation

$y=A *sin(kx+b)+h$ where

A is the amplitude or vertical stretch
k is the period factor
b is the horizontal shift
h is the vertical stretch

We start with $f(x)=sinx$ were A=1 and h=0. We transform the function by multiplying A by 2 for a vertical stretch. A=1(2)=2. A is now 2.

We finish transforming the function by shifting it up 3 units. This means h=0 becomes 0+3=3. H is now 3.

Our new function is $g(x)=2sinx+3$ .

Answer is h= 38.4

Height is approximately equals to 38

Step-by-step explanation:

$Given \: volume \: of \: cone \: = 19808.22528 \: cubic \: feet \\ and \: given \: radius \: is \: 22.2 \: ft \\ to \: find \ \: : h = ? \\ volume \: of \: cone \: = \frac{1}{3} \pi \: {r}^{2} h \\ on \: substituting \: the \: values \: in \: formula \: we \: get \\ 19808 .22528 = \frac{1}{3} \times 3.14 \times {22.2}^{2} \times h \\ on \: solving \: the \: above \: mentioned \: equation \: we \: get \: h = 38.4$
