The probability that Bridget makes all three free throws to win the game is; 42.2%
How to find the probability?
We are told that the probability of Bridget making her free throw correctly is 75%.
Now, if she has to get all three free throws correctly, then the probability for that is;
P(3 free throws correct) = 0.75 * 0.75 * 0.75
P(3 free throws correct) = 0.421875 ≈ 42.2%

Consider the circles A, B, C, and D.
Four circles A, B, C, and D are shown. Circle A has a diameter of 8 feet. Circle B has a diameter of 10 inches. Circle C has a diameter of 2 feet. Circle D has a radius of 50 inches.
a. Without calculating, circle
has the greatest circumference.
Question 2
Explain.
Answer:
Circle D
Step-by-step explanation:
The circumference of a circle can be calculated by multiplying the diameter by π. Therefore, the circle with the greatest circumference will be the circle with the greatest diameter.
The only circle for which we have been told the radius is Circle D. The diameter of a circle is twice the radius, therefore the diameter of Circle D is 50 in × 2 = 100 in
There are 12 inches in 1 ft.
Therefore, the circumferences of the circles in order from smallest to largest is: B < C < A < D

How to determine a family of cubic functions
Cubic functions are polynomials of grade 3. In this case, we have pairs of cubic functions of the following form:
y = (x - h)³ + k (1)
y = - (x - h)³ + k (2)
a) Where (h, k) are the coordinates of the vertex of each cubic function. There is a translation of (x, y) = (3, 1) between each two consecutive pairs of cubic functions. Hence, we have the following fourteen cubic functions:
y = (x + 9)³ - 3y = - (x + 9)³ - 3y = (x + 6)³ - 2y = - (x + 6)³ - 2y = (x + 3)³ - 1y = - (x + 3)³ - 1y = x³ y = - x³y = (x - 3)³ + 1y = - (x - 3)³ + 1y = (x - 6)³ + 2y = - (x - 6)³ + 2y = (x - 9)³ + 3y = - (x - 9)³ + 3b) Another family of functions with a similar pattern is shown below:
y = (x + 9)² - 3y = - (x + 9)² - 3y = (x + 6)² - 2y = - (x + 6)² - 2y = (x + 3)² - 1y = - (x + 3)² - 1y = x² y = - x²y = (x - 3)² + 1y = - (x - 3)² + 1y = (x - 6)² + 2y = - (x - 6)² + 2y = (x - 9)² + 3y = - (x - 9)² + 3To learn more on cubic functions: https://brainly.com/question/25732149

The sides of a square are equal.
Therefore,
let the side of the square = x
Hence,
length = x + 3
width = x + 1
area of rectangle = lw
where

Use vectors to find the interior angles of the triangle with the given vertices. (Enter your answers as a comma-separated list. Enter your answers in terms of degrees. Round your answers to two decimal places.) (−6,-9), (2,7),(7,2)
Answer:
23.20°, 71.57°, 85.24°
Step-by-step explanation:
The angle between two vectors can be found by making use of the definition of the dot product. The computed angle is the angle between the vectors when they are placed tail-to-tail.
__
setupvector definition
The second attachment shows the given points plotted as A, B, C in the order given. In the diagram, the vectors a, b, c are defined as BA, CB, AC, respectively. That is, the vector a is ...
a = A -B = (-6, -9) -(2, 7) = (-6-2, -9-7) = (-8, -16)
The vectors are defined in counterclockwise order around the triangle, though that makes no difference to the calculation.
dot product definition
The definition of the dot product of vectors A and B is ...
A·B = |A|×|B|×cos(θ) . . . . . where θ is the angle between the vectors
Solving for the angle, we find it to be ...
[tex]\theta=\arccos\left(\dfrac{\vec{A}\cdot\vec{B}}{|\vec{A}|\,|\vec{B}|}\right)[/tex]
__
computationBecause of the way the vectors in this solution are defined, the angle between any given pair of vectors will be an exterior angle of the triangle. In order to find the measure of the interior angle, we must reverse one of the vectors. That is, the dot product used in our computation will be the opposite of the dot product of the vectors we have found.
The spreadsheet shown in the first attachment does the necessary computations.
Each vector is the difference of successive points. (x1 -x2, y1 -y2)Each dot product shown is the opposite of the dot product of successive vectors. -(x1x2 +y1y2)The magnitude is computed in the usual way: the root of the sum of the squares of the components of the vector. √(x²+y²)The cosine is the dot product of successive vectors, divided by each of the vector magnitudes.The spreadsheet shows the angle in degrees, having converted it from the radian value produced by the ACOS function.As a check, the spreadsheet shows the sum of the angle values. (The rounded values add up to 180.01°.)
The interior angles of the triangle are 23.20°, 71.57°, 85.24°.

Additional comment
Another way to find the interior angles from coordinates is to consider the slope of each side of the triangle as being the tangent of the angle it makes with the x-axis. The difference of these angles can be used to find the interior angles of the triangle. Less work is involved because there is no dot-product or magnitude computation.

Answer:
y = - 5 or y = 9
Step-by-step explanation:
using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (4, 2 ) and (x₂, y₂ ) = (- 1, y )
d = [tex]\sqrt{(-1-4)^2+(y-2)^2}[/tex]
= [tex]\sqrt{(-5)^2+(y-2)^2}[/tex]
= [tex]\sqrt{25+(y-2)^2}[/tex]
equating to [tex]\sqrt{74}[/tex] , that is
[tex]\sqrt{25+(y-2)^2}[/tex] = [tex]\sqrt{74}[/tex] ( square both sides )
25 + (y - 2)² = 74 ( subtract 25 from both sides )
(y - 2)² = 49 ( take square root of both sides )
y - 2 = ± [tex]\sqrt{49}[/tex] = ± 7 ( add 2 to both sides )
y = 2 ± 7
Then
y = 2 + 7 = 9 or y = 2 - 7 = - 5
In a cave, a stalactite gets 44 millimeters longer each year. this year it is 72 centimeters long. how many years until it is 1 meter long?
Answer:
6.36 years (the .36 repeats), so rounded is 6.4.
Step-by-step explanation:
First, I'm going to convert all measurements to meters.
Since 1000 mm = 1 m, divide 44 by 1000.
44/1000 = 0.044 m
Since 100 cm = 1 m, divide 72 by 100.
72/100 = 0.72 m
Next, I'm going to setup an equation using y = mx + b.
b is the beginning amount which is 0.72.
m in the equation represents the rate which is 0.044.
y represents the total which is 1.
Plugin the numbers and solve for x.
1 = 0.044x + 0.72
1 - 0.72 = 0.044x + 0.72 - 0.72
0.28 = 0.044x
0.28/0.044 = 0.044x/0.044
6.36 = x
