At a certain location, the number of hours of sunlight is modeled by y = 6.4 cosine (StartFraction pi Over 26 EndFraction x) + 12 where x represents the number of weeks after the summer solstice.
Based on the model, what is the minimum number of hours of sunlight at this location?

5.6
6.4
13.0
Answer:
5.6
Step-by-step explanation:
Edge 2020
A correct option is an option (b)
Given,
The function is [tex]y=6.4 cos(\frac{\pi x}{26})+12[/tex]
For minimum hours of sunlight, [tex]cos(\frac{\pi x}{26})[/tex] should have the lowest value, that is -1 for [tex]x=26[/tex] {because [tex]cos (\pi )=-1[/tex] is the lowest value of cosine function}
Thus.
[tex]y_{minimum} = -6.4 + 12 \\y_{minimum}= 5.6[/tex]
So, the option is an option (b)

» A race car game takes 6 points from a player each
time the player hits a cone. What integer represents
the change in total points if the player hits 10 cones?
Answer:
-60
It is -60 because if it takes away 6 points for each cone you hit and you hit 10, then it would be -60 times 10, which equals -60.

The y-intercept is the y-value for when the line intersects with the y-axis. Another way to put this is also the y-value when x=0. This is easy to find when you have a graph because you can simply look to see where on the graph the line intersects with the axis. If you don't have the graph then you can plug 0 in for x in the equation and solve.

The difference between the areas of the figures is less than 6.
Answer:
|24 - (2x - 6)| < 6
x > 12 or x < 18 (12 < x < 18)
Step-by-step explanation:
Area of the triangle = ½*base*height = ½*8*6 = 4*6 = 24 unit²
Area of rectangle = length * width = (x - 3) * 2 = (2x - 6) unit²
Difference in their areas is given as less than 6. This can be represented as an absolute value of inequality as shown below:
|24 - (2x - 6)| < 6
Solve to find the solution of the inequality by splitting into two as follows:
24 - (2x - 6) < 6 OR 24 - (2x - 6) > -6
Solve for each
24 - 2x + 6 < 6
30 - 2x < 6
Subtract 30 from both sides
-2x < 6 - 30
-2x < -24
Divide both sides by -2. < will change to >, since we are dividing by a negative number.
x > 12
Or
24 - (2x - 6) > -6
24 - 2x + 6 > -6
30 - 2x > -6
Subtract 30 from both sides
-2x > -6 - 30
-2x > -36
Divide both sides by -2
x < 18
The solution of the inequality is x > 12 or x < 18
Or can be written as: 12 < x < 18

For employees at a large company, the mean number of overtime hours worked each week is 9.2 hours with a population standard deviation of 1.6 hours. A random sample of 49 employees was taken and the probability that the mean number of overtime hours will be at least 9.3 hours was determined. Was the probability a Left-tail, Right -tail or Interval Probability? Use a calculator to find the probability that the mean overtime hours for the sample will be at least 9.3 hours. Select the two correct answers that apply below.
Complete Question
Answer:
The probability is Right- tailed
The mean overtime hours for the sample will be at least 9.3 hours is
[tex]P(X \ge 9.3 ) = 0.3333[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 9.2 \ hours[/tex]
The standard deviation is [tex]\sigma = 1.6 \ hours[/tex]
The sample size is n = 49
The sample mean is [tex]\= x = 9.3[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{\= x} = \frac{1.6 }{\sqrt{49} }[/tex]
=> [tex]\sigma_{\= x} = 0.22857[/tex]
This is a right -tailed probability because the sample mean is greater than the population mean
Generally the probability that the mean overtime hours for the sample will be at least 9.3 hours is mathematically represented as
[tex]P(X \ge 9.3 ) =1 - P(X < 9.3 )[/tex]
So
[tex]P(X < 9.3 ) = P( \frac{ X - \mu }{ \sigma_{\= x }} < \frac{ 9.3 - 9.2 }{ 0.22857} )[/tex]
Here [tex]\frac{X - \mu }{\sigma _{\= x}} = Z[/tex]
[tex]P(X < 9.3 ) = P( Z < 0.43750)[/tex]
From the z-table
[tex]P(X < 9.3 ) = P( Z < 0.43750) = 0.667[/tex]
So
[tex]P(X \ge 9.3 ) =1 - 0.667[/tex]
[tex]P(X \ge 9.3 ) = 0.3333[/tex]

Your grandmother gave you ₱1000 to start a college book fund. She also promised to add another ₱200 each month, if you add ₱50 monthly. Which rule generates a sequence of the monthly amounts in your college book fund? answer
Answer:
A= ₱1000 + t( ₱250) ------where t is the time in months
Step-by-step explanation:
The principal amount ,P, is given as : ₱1000----- P=₱1000 ------equation (i)
Additional amounts to be added by grandmother = ₱200 monthly
Amount expected to add monthly = ₱50
Additional amounts in total added monthly = ₱200 + ₱50=₱250
Monthly amounts ,A, in the fund after the first month, t =1 month will be:
A=P + ₱250= ₱1000 + 1( ₱250) ------where t= 1, amount at end of month 1
A=P +₱250= ₱1000 + 2( ₱250)--------where t=2, amount at end of month 2
A=P +₱250= ₱1000 + 3( ₱250)---------where t=3, amount at end of month 3
A=P +₱250= ₱1000 + 4( ₱250)--------where t=4, amount at end of month 4
From the breakdown above of 4 months, the general equation of monthly amounts will be;
A= ₱1000 + t( ₱250) ------where t is the time in months
A sequence of the monthly amounts in your college book fund is given by the equation (A = 1000 + 250t) and this can be determined by forming the linear equation with the help of the given data.
Given :
Your grandmother gave you ₱1000 to start a college book fund. She also promised to add another ₱200 each month, if you add ₱50 monthly.The following steps can be used to determine a sequence of the monthly amounts in your college book fund:
Step 1 - Given that the principal amount is ₱1000 which is given by the grandmother.
Step 2 - Additional amount is given by grandmother is ₱200 and each month ₱50 is added. So, the total additional amount each month is:
= 200 + 50
= ₱250
Step 3 - Let 't' be the number of months. So, the linear equation becomes:
A = 1000 + 250(t)
where A is the total amount and t is the time in months.
A sequence of the monthly amounts in your college book fund is given by the equation (A = 1000 + 250t)

The measure of angle 7 in the system created by two non-parallel lines is 108°.
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.
A line that is crossed by a non-parallel line produces four pairs of extra angles, according to geometry. If and only if two angles are close to one another and the sum of their measures is 180 degrees, then those angles are supplementary.
Then, m ∠ 6 + m ∠ 7 = 180° = 72° + m ∠ 7 = 180°.
So, m ∠ 7 = 108°.
Therefore, the measure of angle 7 in the system created by two non-parallel lines is 108°.
