The center of a circle is A (-3,3), and B (1,6) is on the circle. Find the area of the circle in terms of pi.
On her first stroke, Maria hit a golf ball 140 yards, 2 feet, 9 inch. On her second she hit it 170 yards, 1 foot, 6 inches. How far did the ball go all together
2 feet 9 inches + 1 foot 6 inches = 3 feet 15 inches
15 inches = 1 foot 3 inches
3 feet + 1 foot = 4 feet
2 ft 9 inches + 1 ft 6 inches = 4 ft 3 inches
1 yard = 3 feet
4feet 3 inches = 1 yard, 1 foot 3 inches
140+170 = 310 yards
310 + 1 = 311
so it traveled 311 yards 1 foot and 3 inches
Answer:
311 yards and 1 feet and 3 inches

What do the vertical lines mean?
Final answer:
In art, vertical lines suggest stability and structure, contrasting with calming horizontal lines and dynamic diagonal lines. These lines help define shapes, indicate motion, and guide the viewer through the composition.
Explanation:
The term vertical lines in the context of art and design, refers to lines that run up and down the canvas or design space, perpendicular to the horizon. These lines can convey a variety of meanings and emotions in visual compositions. According to a description by Oliver Harrison, vertical lines are seen as visually stable and can be associated with structures like tree trunks or classical columns, suggesting strength and stability.

3/3 would be 1 hour
3/18 of the lawn would be done in 1 hour
18/3=6
6*1 = 6
it would take 6 hours to do the whole lawn
It will take 360 minutes to water the entire lawn
What is cross multiplication?Cross multiply can be defined as the process of multiplying the numerator of the first fraction on one side of the equals to symbol, with the denominator of the second fraction on the other side of the equals to symbol.

B is between a and c ac=15.8 and ab=9.9. find bc
Answer:
The value of bc is 5.9 units.
Step-by-step explanation:
Given information: b is between a and c, ac=15.8 and ab=9.9.
We need to find the measure of bc.
Since b is between a and c, therefore the segment ac is the sum of two segments ab and bc.
[tex]ac=ab+bc[/tex]
Substitute ac=15.8 and ab=9.9 in the above equation.
[tex]15.8=9.9+bc[/tex]
Subtract 9.9 from both sides.
[tex]15.8-9.9=9.9+bc-9.9[/tex]
[tex]5.9=bc[/tex]
Therefore the value of bc is 5.9 units.
If assumption of Collinearity is not for granted, then the length of Segment BC is defined by [tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex], for [tex]\beta \in [0^{\circ}, 180^{\circ}][/tex].
Reminder - Given that statement seems to be incomplete, we assume that we are talking about Line Segments and that Segments AC and BC may be Collinear.
By Geometry and, being more specific, by definition of Triangles, if we assume that all segment are not necessarily Collinear, then a Triangle may exist and can be modelled by the Law of Cosine:
[tex]BC = \sqrt{AC^{2}+AB^{2}-2\cdot AC\cdot AB\cdot \cos \beta}[/tex] (2)
Where [tex]\beta[/tex] is the angle at point B, in sexagesimal degrees and is between 0° and 180°.
If we know that [tex]AC = 15.8[/tex] and [tex]AB = 9.9[/tex], then the expression for the length of BC is:
[tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex]
If assumption of Collinearity is not for granted, then the length of Segment BC is defined by [tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex], for [tex]\beta \in [0^{\circ}, 180^{\circ}][/tex].

Sally found that a solution of x = 2 was extraneous for her function. What would be a possible denominator in Sally's function?
4x + 8
2x + 12
x^2 − 4
x^2 − 16
Answer:
[tex]x^2-4[/tex]
Step-by-step explanation:
Sally found that a solution of x = 2 was extraneous for her function.
Extraneous solution is a solution that makes the denominator 0
Possible denominator are given . LEts plug in 2 for x and check which option gives us 0
[tex]4x+8=4(2)+8= 16[/tex]
[tex]2x+12=2(2)+12=4+12= 16[/tex]
[tex]x^2-4= (2)^2-4= 4-4=0[/tex]
[tex]x^2-16= (2)^2-16= 4-16= 12[/tex]
[tex]x^2-4[/tex] gives us 0 when we plug in 2 for x.
So x=2 was extraneous solution for [tex]x^2-4[/tex]

Scientists studied two animal populations. Function f(x) = 830(0.8)^x models a bear population in a given region x years after the study began. The table models the cougar population in the same region.
Year after study began: 0, 1, 2, 6, 15
Cougar population: 790, 735, 683, 511, 266
In the year the study began, how many more bears than cougars were in the given region.
Answer:
There were 40 more bears than cougars when the study started.Step-by-step explanation:
Givens:
[tex]f(x)=830(0.8)^{x}[/tex]; where [tex]x[/tex] refers to years after the study began, about bear population.Table given is for cougar population.So, the problem is asking how many more bears than cougars were in the given region. From the table, we know that there where 790 cougar when the study started.
Now, we have to calculate the initial condition of the function, because it's modelling bear population. Initial condition means when the study started, which is when [tex]x=0[/tex].
So, we have:
[tex]f(0)=830(0.8)^{0}=830(1)=830[/tex]
So, there were 830 bears when the study started.
If we compare, we find that there were 40 more bears than cougars when the study started, because 830-790 = 40.

the quadratic equation whose roots are the am and hm between the roots of the equation 2x2 - 3x+5=0
The first thing to do is to find the roots.
The sum of the roots, x1 + x2 = -b / a
x1 + x2 = 3 / 2
The product of the roots, x1 * x2 = c / a
x1 * x2 = 5 / 2
The AM means arithmetic mean and is calculated using the formula:
AM = (x1 + x2) / 2
AM = (3 / 2) / 2
AM = 3 / 4 = y1
The HM means harmonic mean and is calculated using the formula:
2 / HM = 1 / x1 + 1 / x2
or
2 / HM = (x1 + x2) / x1 * x2
Rewriting in terms of HM alone on the left side:
HM = 2 x1*x2 / (x1 + x2)
HM = 2 (5 / 2) / (3 / 2)
HM = 10 / 3 = y2
Creating an equation from y1 and y2:
(y – ¾) (y – 10/3) = 0
y^2 – 10/3 y – ¾ y + 30/12 = 0
y^2 - 49/12 y + 30/12 = 0 (ANSWER)
or
y^2 – 4.083y + 2.5 = 0

Find the probability that 3 randomly selected people all have the same birthday. ignore leap years. round to eight decimal places.\
The probability that 3 randomly selected people all have the same birthday is 1 in 48,627,125.
Explanation:In order to find the probability that 3 randomly selected people all have the same birthday, we need to consider the total number of possible outcomes and the number of favorable outcomes. There are 365 days in a year (excluding leap years) and each person's birthday is independent of the others. Therefore, the probability of each person having the same birthday as the previous person is 1/365. To calculate the probability that all 3 people have the same birthday, we multiply the probabilities together:
P(3 people have the same birthday) = (1/365) * (1/365) * (1/365) = 1/48,627,125
Thus, the probability that 3 randomly selected people all have the same birthday is approximately 0.0000000206, rounded to eight decimal places.
