x = -5/6
Step-by-step explanation:
Since it is on the unit circle
x^2 + ( -sqrt(11)/6)^2 = 1 ^2 (pythagorean theorem)
x^2 = 1 - 11/36
x^2 = 25 /36
x = +-5/6 since x is in Q III it is the negative
Judging by appearance, is it reasonable to say that the figures below are similar? How do you know?
Answers
Answer:
C
Step-by-step explanation:
the proportions all seem to stay the same, so while the second figure is smaller, all parts of the figures seem to follow the same scaling factor.
there are 8 isoceles triangle "rays" emanating from a central circle in both figures. so, also the main characteristics are the same.
the smaller figure appears rotated compared to the other.
so, it was rotated and then dilated (or vice versa, as the sequence of these 2 operations is irrelevant).

Answers
Answer:
B
Step-by-step explanation:
One easy way to solve this (considering it's on paper) would be to just plot the points of each option (because a rectangle is a quadrilateral which is equiangular (right angles) and a parallelogram).
Another way to solve this is the fact that it's angles are right angles. This means that a point has to be on the line y=5 and another point has to be on the line y=1. This means that the y coordinates of the other two points has to be 5 or 1, making the only possible answer B.

Your friend asks you to help him study and will pay you 5 dimes the first time you help him. You agree to help if he multiplies your payment by 5 for each study session. After 2 study sessions, you will receive 25 dimes, and after 3 study sessions, you will receive 125 dimes.
Complete and solve the equation that finds the number of dimes he will pay you after the 7th study session.
Answers
Answer:
78125 dimesStep-by-step explanation:
The payment for sessions makes a series
5 dimes, 5*5 = 25 dimes, 25*5 = 125 dimes, ...This series is GP with the first term of 5 and common ratio of 5.
The nth term would be
[tex]t_n=5*5^{n-1}[/tex]Use the equation above and find the 7th term
[tex]t_7=5*5^6 = 5^7 = 78125[/tex]Answer:
[tex]a_7=5(5)^{6}[/tex]
78125 dimes
Step-by-step explanation:
The given scenario can be modeled as a geometric sequence.
A geometric sequence has a common ratio (multiplier) between each term, so each term is multiplied by the same number.
General form of a geometric sequence:
[tex]a_n=ar^{n-1}[/tex]
where:
n is the nth terma is the first termr is the common ratioGiven:
The friend will pays 5 dimes the first time you help him.Therefore, a = 5
Given:
The friend multiplies your payment by 5 for each study session.Therefore, r = 5
Substitute these values into the formula to create an equation for the nth term.
[tex]\implies a_n=5(5)^{n-1}[/tex]
To find the number of dimes he will pay after 7 sessions, simply substitute n = 7 into the found equation:
[tex]\implies a_7=5(5)^{7-1}[/tex]
[tex]\implies a_7=5(5)^{6}[/tex]
[tex]\implies a_7=5 \cdot 15625[/tex]
[tex]\implies a_7=78125[/tex]
Therefore, the friend will pay 78125 dimes after the 7th study session.

e.g. you have y = x^2 - 6x + 9, compare this to the general quadratic equation y=ax^2 + bx + c

For the graph to only touch x axis at one point discriminant must be equal to 0 so D is the answer as it is the only equations whose discriminant is equal to 0

The average monthly temperature in New Orleans, LA has a mean absolute deviation of 43.5*F what conclusion can you make about the average monthly temperatures in New Orleans, La.
Answers
The average monthly temperature in New Orleans, LA varies on average about 43.5°F from its monthly mean temperature.
How to find the mean absolute deviation of a discrete data?Suppose the data specified is of n sized as
[tex]x_1, x_2, \cdots , x_n[/tex]
Let this data's mean be [tex]\bar{x}[/tex]
Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.
It is calculated as:
[tex]M.A.D = \dfrac{\sum_{i=1}^n|x_i-\bar{x}|}{n}[/tex]
So, Mean Absolute deviation is the average of the deviation (not caring if its above or below the mean) of the data values.
Since it is given that:
Mean absolute deviation of the temperatures (monthly) in New Orleans = 43.5°F, therefore, it means, the temperature averagely varies 43.5°F from its monthly average value.
where mean shows the average monthly temperature in New Orleans, LA.
Thus, the average monthly temperature in New Orleans, LA varies on average about 43.5°F from its mean temperature.

Exactly how many radians are in
? In
Answers
Answer:
Step-by-step explanation:
They want you to see how radius is important. Just remember that one radian is one radius, that should help you see why radius is important.
They ask for the unit circle , that is a circle of one unit for the radius, which makes it super easy to calculate things for it, they ask what is the area, which is that famous formula, π[tex]r^{2}[/tex] , then they ask what's its circumference. which is that other famous formula 2πr
so to go all the way around a circle of one unit radius, it's 2π exactly or about 6.28..... units, call it meters, or feet or inches, it doesn't mater here.
the size of the circle doesn't matter here either, b/c we are using the radius , that relaationship doesn't change , all circles, what ever size , have this same relationship between the radius and radians. :P this is handy.
