Answer:

f(x)=1.5cos(16πx)+1.5

(Question on a Quiz was correct)

The trigonometric equation is f ( x ) = 1.5cos ( 16πx ) + 1.5 , when x = 3 feet , the height of the nail from the ground is 3 feet

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the trigonometric equation be represented as A

Now , the value of A is

f ( x ) = 1.5cos ( 16πx ) + 1.5

Let the diameter of the tire be x

Let the height of the nail from ground be f ( x )

On simplifying , we get

when x = 3 feet

f ( 3 ) = 1.5 cos ( 16π ( 3 ) ) + 1.5

f ( 3 ) = 1.5 cos ( 48π ) + 1.5

From the trigonometric relation cos ( nπ ) = 1

f ( 3 ) = 1.5 + 1.5 = 3 feet

Hence , the height of the nail from the ground is given by the equation with f ( x ) = 1.5cos ( 16πx ) + 1.5

Answer: -30

Step-by-step explanation:

My answer is correct because, All you have to do is subtract all the numbers by 11 and the one that has the sum -19 is the correct choice. In this case -30 does and we can make sure were orrect by subtracting 11 by -19 and that equals -30.

Answer:

Step-by-step explanation:

Here we want the side length of x, which is adjacent to the angle 31 degrees. Cosine is the ratio we want because it is adj/hypotenuse.

Here's our basic equation:

cos31=x/17

or

17 * cos31=x

Put this into the calculator and you get around 15.6

Answer:

280 square units

Step-by-step explanation:

Area of the rectangle:

  A = b* h = 16 * 15 = 240

Area of the triangle:

   A = bh/2 = (16*5)/2 = 40

Total area = area of triangle + area of rectangle = 240 + 40 = 280 square untis.

Answer:

0.0824 (may be incorrect)

In triangle ABC angle c = 180-78-40 = 62 degrees

For the triangles to be congruent angle z must equal angle C

Solve for x:

2x + 8 = 62

Subtract 8 from both sides:

2x = 54

Divide both sides by 2:

X = 27

Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.

A. False

B. True

C. True

Answer:

25/8

Step-by-step explanation:

The question can be interpreted as

Y= k/x^2.......eqn(1)

Where k= constant if proportionality

y = 1/8 when x = 1,

Substitute, we have

1/8= k/(1)^2

1/8= 1/k

Cross multiply

K= 1/8

find y when x = 5

From eqn(1)

Y= k/x^2

Y= (1/8)/(5)^2

Y=1/8 ×25

Y= 25/8

the circumference is the total distance round a circle but the are is a measure of a space or region inside the circle but circumference is around it

Answer:

C

Step-by-step explanation:

The average rate of change on an interval is simply the slope between the endpoints.

We want to find the average rate of change of function y from x= 3 to x = 5.

Find the endpoints. From the table, we know that the endpoints are (3, 27) and (5, 125).

The slope between them is:

[tex]\displaystyle m=\frac{125-27}{5-3}=49[/tex]

So, the average rate of change of function y from x = 3 to x = 5 is 49.

Our answer is C.

C. 49

Area brother ate = 1/6 x area of pizza

a pizza is the shape of a circle. the area of a pizza is equal to the area of a circle

Area of a circle = πr²

r = 12/2 = 6

he diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x 6^2 = 113.04

1/6 x 113.04 = 18.84
