Answers
Answer:
a) [tex]F=0.16Hz[/tex]
b) [tex]\omega=1rad/s[/tex]
c) [tex]L=9.54m[/tex]
d) [tex]g=9.46m/s^2[/tex]
Step-by-step explanation:
From the question we are told that:
Time [tex]T =6.2[/tex]
a)
Generally the equation for Frequency F is mathematically given by:
[tex]F=\frac{1}{T}[/tex]
[tex]F=\frac{1}{6.2}[/tex]
[tex]F=0.16Hz[/tex]
b)
Generally the equation for Frequency F is mathematically given by:
[tex]\omega=2\pi f[/tex]
[tex]\omega=2*314* 0.16[/tex]
[tex]\omega=1rad/s[/tex]
c)
Generally the equation for Length of Chandelier L is mathematically given by:
Since
[tex]T=2*3.142\sqrt{\frac{L}{g}}[/tex]
Therefore
[tex]L=\frac{gT^2}{4 \pi^2}[/tex]
[tex]L=\frac{9.8*(6.2)^2}{4 \pi^2}[/tex]
[tex]L=9.54m[/tex]
d)
Since
Michelson exhibit except this one swings back and forth 0.11 seconds slower
Therefore
[tex]T'=T+0.11[/tex]
[tex]T'=6.31[/tex]
Generally the equation for acceleration due to gravity g is mathematically given by:
[tex]g = \frac{4\pi ^2L}{( T')}^2[/tex]
[tex]g = \frac{4\pi ^2L\*9.54}{( 6.31 s )}^2[/tex]
[tex]g=9.46m/s^2[/tex]

Find the intercepts and use them to graph the equation. y=x-4
Answers
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]y = x -4[/tex]
The intercepts
For y intercept, we have: [tex]x =0[/tex]
[tex]y = x -4[/tex]
[tex]y = 0 - 4[/tex]
[tex]y = - 4[/tex]
For y intercept; we have: [tex]y = 0[/tex]
[tex]y = x -4[/tex]
[tex]0 = x - 4[/tex]
[tex]x = 4[/tex]
So, the intercepts are: (0,-4) and (4,0)

Which inequality shows all possible values for the measure of the third side, x, in inches?
Answers
Answer:
[tex]26 > c > 58[/tex]
Step-by-step explanation:
Given
[tex]a,b =42; 16[/tex] --- 2 sides
Required
The inequality for the third side
To do this, we make use of:
[tex]a + b < c[/tex]
[tex]a + c < b[/tex]
[tex]b + c < a[/tex]
So, we have:
[tex]42 + 16 < c[/tex]
[tex]16 + c < 42[/tex]
[tex]42 + c < 16[/tex]
This gives:
[tex]58 < c[/tex]
[tex]c < 26[/tex]
[tex]c<-26[/tex]
The usable inequalities are:
[tex]c < 26[/tex] and [tex]58 < c[/tex]
Rewrite:
[tex]c < 26[/tex] and [tex]c > 58[/tex]
So, the inequality is:
[tex]26 > c > 58[/tex]
Cook-Easy blender has a mean time before failure of 41 months with a standard deviation of 4 months, and the failure times are normally distributed. What should be the warranty period, in months, so that the manufacturer will not have more than 8% of the blenders returned
Answers
Answer:
The warranty period should be of 35 months.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Cook-Easy blender has a mean time before failure of 41 months with a standard deviation of 4 months
This means that [tex]\mu = 41, \sigma = 4[/tex]
What should be the warranty period, in months, so that the manufacturer will not have more than 8% of the blenders returned?
The warranty period should be the 8th percentile, which is X when Z has a p-value of 0.08, so X when Z = -1.405.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.405 = \frac{X - 41}{4}[/tex]
[tex]X - 41 = -1.405*4[/tex]
[tex]X = 35.4[/tex]
Rounding to the nearest integer, 35.
The warranty period should be of 35 months.

The value of cos 60 is 1/2 from the given triangle, Option E is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Let the given triangle is ABC.
AB=1, BC=√3 and AC = 2.
We have to find the value of cos 60 degrees.
We know that cos function is a ratio of adjacent side and hypotenuse.
cos 60 = Opposite side/ Hypotenuse
=AB/AC
Plug in the value of AB and AC.
cos 60 =1/2
Hence, the value of cos 60 is 1/2 from the given triangle, Option E is correct.

Terry Sheehan owns property assessed at $390,000 and pays a property tax rate of 1.69 per hundred dollars of assessed value. He charges $690 per month rent to cover his
property tax bill. How much more rent does he collect each year above the annual property tax bill?
$2,090
$1.769
$1,854
$1,689
None of these choices are correct.
Answers
Answer:
$1689
Step-by-step explanation:
Excess of rent amount over annual property tax bill = annual rent - annual property tax
annual property tax = [(assessed property value / 100) x 1.69]
( $390,000 / 100) x 1.69 = $6591
Annual rent = $690 x 12 = $8280
$8280 - $6591 = $1689

In another right angle triangle the hypotenuse is 53, and the one of the side lengths is 28. Please find the missing side length.
Answers
Answer:
Adjacent, b = 45 units
Step-by-step explanation:
Let the length of sides of the triangle be;
Opposite side = aAdjacent side = bHypotenuse side = cGiven the following data;
Hypotenuse, c = 53 units
Opposite, a = 28 units
To find the missing side (adjacent), we would have to apply Pythagorean' theorem.
From Pythagorean theorem;
c² = a² + b²
Substituting into the formula, we have;
53² = 28² + b²
2809 = 784 + b²
Rearranging the equation (collecting like terms), we have;
b² = 2809 - 784
b² = 2025
Taking the square root of both sides, we have;
b = √2025
Adjacent, b = 45 units

In other words, the point [tex]\left( \frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2} \right)[/tex] is on the unit circle for the angle pi/4 radians. This point is equivalent to [tex]\left( \frac{1}{\sqrt{2}}, \frac{1}{\sqrt{2}}\right)[/tex]
==============================================
Explanation:
The angle pi/4 radians is equivalent to 45 degrees. Draw out a 45-45-90 triangle with hypotenuse 1, and you'll find the congruent legs are each [tex]\frac{1}{\sqrt{2}}[/tex] units long (apply the pythagorean theorem). If you apply the sine and cosine ratios, you'll get the answer shown above.
