2R = 1D

d=44

Answer is B.

d=44

Answer is B.

**Answer: The given statement is FALSE.**

**Step-by-step explanation: **We are given **to check whether he following statement is true or false :**

"The sine of an angle in a right triangle is equal to the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse. "

Let us consider the right-angled triangle ABC as shown in the attached figure below.

With respect to acute angle C, we can see that

**perpendicular, p = AB**

**base, b = BC **

**and**

**hypotenuse, h = AC.**

We know that

**sine of an angle in a right-angled triangle is equal to the ratio of the perpendicular to the base.**

**So, we must have**

**Since AB is the opposite side to angle C, not adjacent, therefore**

**sine of any angle in a right-angled triangle is the ratio of the length of the OPPOSITE SIDE to length of the hypotenuse.**

**Thus, the given statement is FALSE.**

A regular dodecagon is a polygon with 12 equal sides.

Length of each side = 108/12 = 9 cm.

Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm

Area of each triangle = 9/2(16.79) = 75.57 cm^2

Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2

Length of each side = 108/12 = 9 cm.

Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm

Area of each triangle = 9/2(16.79) = 75.57 cm^2

Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2

QUESTION POSTED AT 16/02/2020 - 04:10 PM

The equation of a circle with center (a, b) and radius = r is given by (x - a)^2 + (x - b)^2 = r^2

If center is (-11, 3) and radius is 9, then equation is

(x - (-11))^2 + (y - 3)^2 = 9^2

(x + 11)^2 + (y - 3)^2 = 81

If center is (-11, 3) and radius is 9, then equation is

(x - (-11))^2 + (y - 3)^2 = 9^2

(x + 11)^2 + (y - 3)^2 = 81

F(t) = -17.5sin((t/4)*pi) + 17.5

Because the ferris wheel is a circle you can use sine and cosine. As we are descending and in the middle of the descent the use of negative sine makes the most sense.

Period = 2pi.

Our period is 8 minutes.

8 minutes*w = 2pi

w = (t/4) * pi.

The 17.5 at the end is to take into account that we are 17.5 meteres up in the air at the start.

You can do what the directions say and enter the function into a calculator. if you're having trouble learning how to graph on a calculator, i would suggest looking up a tutorial with pictures or videos, since it would be really confusing to explain through text alone on this site.

however, you can solve it without use of a calculator; just plug in 1.5 inches for*d*.

h = 2(1.5) + 4.3

h = 7.3

the height is 7.3 when the diameter is 1.5

the way you should find this on a graph entered into a calculator would be by "tracing" the graph ("trace" should be a button on your calc). it prompts you to pick like a left/right bound, if i remember correctly, and it'll guess the point in the middle of them. if a graphing tutorial isn't helpful, you can always refer to the table function as well and change the settings so that it lets you enter your own x-values (yet another thing you can find how to do in the instruction booklet that came with your calc, or a visual tutorial). sorry i couldn't be more helpful in regards to the actual graphing! it's just a pretty confusing process to explain unless you can physically show the person with a calc of your own

**Answer:**

**The length of the shorter piece of the board is 7 ft.**

**Step-by-step explanation:**

Given,

The 25-foot board into 2 pieces.

Let x be the length of one piece,

So, the length of the other piece = ( 25 - x ) feet,

Now, according to the question,

25 - x = 2x + 4

-x - 2x = 4 - 25

-3x = - 21

x = 7

Hence, the length of two pieces are 7 feet and 18 feet,

In which **7 feet is the length of shorter piece.**
