Carlos has a nail in his car tire. The tire is not flat, but he's on his way to get it fixed. He's driving at a constant speed, and the diameter of the tire is 3 feet.
Which rule could model the height of the nail from the ground?
a) f(x)=1.5cos(16πx)+1.5
b) f(x)=1.5cos(16πx)−1.5
c) f(x)=3cos(16πx)+3
d) f(x)=16πcos(1.5x)+3
Answers
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
What are trigonometric relations?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

Help me please use number 0 -9
Answers
Answer:
8÷4+7-3 =6
8÷4+2-1 =3
6÷2+5-1 = 7
5÷1+6-2= 9
0÷5+4+3= 1
(1) The missing numbers are 2 and 5
(2) The missing numbers are 4 and 0
(3) The missing numbers are 6 and 8
(4) The missing numbers are 1 and 9
(5) The missing numbers are 7 and 3
The solution to the given problem is as follows;
In order of mathematical operation, we resolve division first before addition and finally subtraction.
In this problem we are to choose numbers from 0 to 9 and assume that no number will be repeated.
(1) (8 ÷ 2) + (5 - 3) = 6
⇒ 4 + 2 = 6
so the missing numbers are 2 and 5
(2) (4 ÷ 4) + (2 - 0)= 3
⇒ 1 + 2 = 3
so the missing numbers are 4 and 0
(3) (6 ÷ 2) + (6 - 1) = 8
⇒ 3 + 5 = 8
so the missing numbers are 6 and 8
(4) (5 ÷ 1) + (6 - 1) = 9
so the missing numbers are 1 and 9
(5) (0 ÷ 7) + (4 - 3) = 1
so the missing numbers are 7 and 3
Thus, all the numbers from 0 to 9 have been used and non was repeated.

This table shows a value that represents an exponential function what is the average rate of change for this function for the interval from x=3 to x=5?
Answers
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.

If y varies inversely as the square ofx, and y = 1/8 when x = 1, find y when x = 5
Answers
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

2x = 54
Divide both sides by 2:
X = 27
