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

Find the measure of x. (to the nearest tenth)

Trig ratios = sOH, cAH, tOA
In the figure we are finding the opposite and we have the adjacent, therefore we are gonna use the ratio tOA.
tOA states tangent theta (angle) is equal to opposite over adjacent or Tan theta =opp/adj where opp = x and adj = 19
Therefore;
Tan 41 = x/19
Solve for x
x = 19 tan 41
= 16.5

(b) Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.
Answers
Answer:
√18 = 3√2
Step-by-step explanation:
the square root of 18 = √18
18;
1 × 18 = 18
2 × 9 = 18
3 × 6 = 18
6 × 3 = 18
9 × 2 = 18
18 × 1 = 18
9 has a perfect square
So,
√18 = √(2*9)
= √2 * √9
= 3√2
√18 = 3√2
Perfect square
1 × 1 = 1
2 × 2 = 4
3 × 3 = 9
4 × 4 = 16
5 × 5 = 25
Therefore,
√18 is between 4 and 5
A jar contains 15 quarters, 9 dimes, 10 nickels and 6 pennies. A coin is selected at random, not replaced, then another coin is selected. Find the probability of the event. P(quarter, then penny)
Answers
Answer: 0.058
Step-by-step explanation:
Number of quarters = 15
Number of dimes = 9
Number of nickels = 10
Number of pennies = 6
Total number of coins = 40
The probability of selecting a quarter first will be 15/40 = 3/8
Since it's not replaced, there'll be 39 coins left and the probability of choosing a penny is 6/39 = 2/13
Therefore, P(quarter, then penny) will be:
= 3/8 × 2/13
= 6/104
= 0.058

Insert two rational numbers between-1/3 and 2/3. with explanation with whole process
Answers
Answer:
Two rational numbers between -1/3 and 2/3 are:
0 and 1/3
Step-by-step explanation:
A rational number is a number that can be written as the quotient of two integer numbers.
Here, we want to find two rational numbers that are between:
-1/3 and 2/3
So, our numbers need to be larger than -1/3 and smaller than 2/3
This is ratter simple, let's start with the lower limit (-1/3) let's add a rational number to it.
Then check, the new number meets the conditions? if not, then we try adding a smaller rational number and so on.
Just because in both cases we have a denominator 3, i will add numbers that also have a denominator of 3.
First try:
Let's try adding 1/3
-1/3 + 1/3 = 0
the number 0 is a rational number: 0 = 0/1
and is true that:
-1/3 < 0 < 2/3
So we already found one of the rational numbers.
Now let's try again, let's add 5/3 this time
-1/3 + 5/3 = (-1 + 5)/3 = 4/3
This is larger than 2/3, so this is not in the desired range.
Let's try again, this time adding 2/3
-1/3 + 2/3 = (-1 + 2)/3 = 1/3
is true that:
-1/3 < 1/3 < 2/3
So the number 1/3 is in the desired range, so we found the second rational number.
You can see that this is kinda a trial and error way to solve these problems, this is the "easier" way to start, as you work with this, eventually you will practice enough and will be easy to find numbers between given ranges.
In triangle $DEF,$ $\angle D = 30^\circ,$ $\angle F = 60^\circ,$ and $EF = 6.$ Find $DE + DF.$
Answers
Answer:
22.39
Step-by-step explanation:
angle D + angle F + angle E = 180 (angle of triangle)
30 +60 + E = 180
E = 180 - 90
E = 90
so triangle DEF is right angled triangle
we know that,
sin 30 = EF /DF
OR, 1/2 = 6/ DF
OR, DF= 12
again,
cos 30 = De/DF
root3 /2 = DE /12
DE= 10.39
hence DF +DE
= 12 + 10.39
= 22. 39
x+4/9=3/4 what is x?
Answers
Answer:
11/36
Step-by-step explanation:
To answer this, you must first convert your fractions to have the same denominators (so you can add and subtract them). I switched it to 36ths. So, the equation would be x+16/36=27/36. When you subtract 16/36 from 27/36 you get 11/36. This cannot be simplified, so 11/36 is the answer. I hope it helps.

Answer:
47 -6√10
Step-by-step explanation:
As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.
(a -b)² = a² - 2ab + b²
(√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²
= 2 - 6√10 + 3²(5)
= 47 -6√10
__
Check
√2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals
(√2-3√5)² ≈ 28.02633
47 -6√10 ≈ 28.02633

The hour hand of a clock moves clockwise from 3 to 5. What is the measure of the angle that the hour hand cuts
Answers
Answer:
Angle covered by the hour hand = 60°
Step-by-step explanation:
Numbers mentioned on an analogue clock = 12
Number of sectors between two numbers = 1
Angle between two numbers or 1 sector = [tex]\frac{360^0}{\text{Total numbers on the clock}}[/tex]
= [tex]\frac{360^0}{12}[/tex]
= [tex]30^0[/tex]
If the hour hand moves clockwise from 3 to 5, sectors covered = 2
Therefore, angle between two sectors = 2 × 30°
= 60°
Angle covered by the hour hand = 60°

y-intercept (0, -6)
x-intercept (-8, 0)
Step-by-step explanation:
You're writing the coordinates of the points where the line crosses the axes.
The y-intercept is where the line crosses the y-axis. The y-coordinate there is -6. Because it is the y-axis, the x-coordinate is 0. Written as an ordered pair, the y-intercept is (0, -6).
The x-intercept is where the line crosses the x-axis. The x-coordinate there is -8. Because it is the x-axis, the y-coordinate is 0. Written as an ordered pair, the x-intercept is (-8, 0).
