Find the rectangular coordinates of the point with the polar coordinates (8, 3 divided by 2 pi ). (1 point) (0, -8) (0, 8) (8, 0) (-8, 0)
Answer:
(x,y) = (0,-8)
Step-by-step explanation:
We know that a point in polar coordinates is represented by
(r, θ)
Where r is the distance from the origin and θ is the angle.
Rectangular coordinates can be found by
x = r*cos(θ)
y = r*sin (θ)
x = r*cos(θ) = 8* cos (3π/2)
y = r*sin (θ) = 8 sin(3π/2)
x = 8* cos (3π/2) = 8*0 = 0
y = 8* sin (3π/2) = 8*(-1) = -8
(x,y) = (0,-8)
Correct option is (A) (0,-8)
Now any point in polar coordinates is represented by
(r, θ)
where 'r' is the distance from the origin
and 'α' is the angle.
Rectangular coordinates can be found by using the formula:
[tex]x=r*cos(\alpha )\\y=r*sin(\alpha )[/tex]
Thus the x coordinate would be given as :
[tex]x=r*cos(\alpha )\\x=8*cos(\frac{3\pi }{2} )\\x=8*0\\x=0\\[/tex]
Similarly the y coordinate would be given as :
[tex]y=r*sin(\alpha )\\y=8*sin(\frac{3\pi }{2} )\\y=8*(-1)\\y=-8\\[/tex]
Thus (x, y) = (0,-8) is the required coordinates

A fair coin is tossed three times in succession. Find the probability if getting exactly one tail
Answer:
If a fair coin is tossed three times, sample = 2^3 = 8 (hhh, hht, hth, thh, htt, tht, tth, ttt) where h=head and t=tail.
Probability of getting one:
Outcomes with one head (h) = 3
P(1 h) = 3/8 = 0.375
The probability of getting exactly one tail when a fair coin is tossed three times in succession is 37.5%.
Explanation:The probability of getting exactly one tail when a fair coin is tossed three times in succession can be found using the binomial probability formula.
Let's denote success as getting a tail and failure as getting ahead. The probability of success, denoted as p, is 0.5 since the coin is fair and has an equal chance of landing on heads or tails. The probability of failure, denoted as q, is also 0.5.
Using the binomial probability formula: P(X = k) = [tex]C(n, k) * p^k * q^(n-k)[/tex], we can calculate the probability as follows:
n = 3 (number of trials) k = 1 (number of tails desired) C(n, k) = C(3, 1) = 3 (number of ways to choose 1 tail from 3 trials)[tex]p^k = 0.5^1[/tex] = 0.5 (probability of getting 1 tail)[tex]q^(n-k) = 0.5^(3-1)[/tex] = 0.25 (probability of getting 2 heads)Plug these values into the formula: P(X = 1) = 3 * 0.5 * 0.25 = 0.375 (or 37.5%)Therefore, the probability of getting exactly one tail when a fair coin is tossed three times in succession is 0.375 or 37.5%.

Use factoring and the zero-product property to solve the following problems.
Answer:
see explanation
Step-by-step explanation:
Divide through by 2
2a² - 5a + 3 = 0
To factor the quadratic
Consider the factors of the product of the coefficient of the a² term and the constant term which sum to give the coefficient of the x- term
product = 2 × 3 = 6 and sum = - 5
The factors are - 2 and - 3
Use the factors to split the a- term
2a² - 2a - 3a + 3 = 0 ( factor the first/second and third/fourth terms )
2a(a - 1) - 3(a - 1) = 0 ← factor out (a - 1)
(a - 1)(2a - 3) = 0
Equate each factor to zero and solve for a
a - 1 = 0 ⇒ a = 1
2a - 3 = 0 ⇒ 2a = 3 ⇒ a = [tex]\frac{3}{2}[/tex]

A 65 inch wide screen television actually describes the length of the diagonal of a rectangular television with a length of 63 inches. What is the width of the television?
For this question we need to use the Pythagorean Theorem (a2+b2=c2) since the rectangle is being divided into two triangles.
we know the length of the triangle (63) and we know the hypotenuse (65) but not the width. To find the width, we can plug the values we know into our formula.
(63) squared + b squared = (65) squared
solve.
3969 + b squared = 4225
subtract 3969 from both sides.
b squared = 256
√b² = √256
b=16
Caleb's puppy weighs 2,250 grams. If the puppy weighed 600 grams at his last visit to the veterinarian's office, what is the percent increase in the puppy's weight rounded to the nearest whole number?

The perimeter of a playing field for a certain sport is 320 ft. The field is a? rectangle, and the length is 48 ft longer than the width. Find the dimensions.
Answer:
length: 104 ftwidth: 56 ftStep-by-step explanation:
Let L and W represent the length and width of the field. Then the perimeter is given by ...
P = 2(L +W)
Filling in the given information, we have ...
320 = 2(L +W)
L = W +48 . . . . . . the length is 48 ft longer than the width
Using the second equation in the first, we get
320 = 2((W +48) +W)
320 = 4W +96 . . . . . . simplify
224 = 4W . . . . . . . . . . subtract 96
56 = W . . . . . . . . . . . . .divide by 4
L = 56 +48 = 104 . . . . find L using the above relation
The width of the field is 56 ft; the length is 104 ft.
The width of the playing field is 56 ft and the length is 104 ft.
Explanation:To solve this problem, let's set up an equation using the information given. Let's say the width of the field is x ft. Since the length is 48 ft longer than the width, the length can be represented as x + 48 ft. The formula for the perimeter of a rectangle is P = 2(l + w), so we can set up the equation: 320 = 2(x + 48 + x). Now, we can solve for x by simplifying and solving the equation.
320 = 2(2x + 48)
320 = 4x + 96
4x = 320 - 96
4x = 224
x = 224/4
x = 56
So, the width of the field is 56 ft and the length is 56 + 48 = 104 ft.
To solve this problem, we must use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.
According to the question, the length is 48 ft longer than the width, therefore we could express the length as L = W + 48. The perimeter provided is 320 ft. Now we can plug these values into the perimeter formula.
320 = 2(W + 48) + 2W
After simplification, this formula becomes 320 = 4W + 96.
To isolate W, you subtract 96 from both sides to get: 320 - 96 = 4W + 96 - 96, which simplifies to 224 = 4W. Dividing both sides by 4 gives W = 56 ft. This is the width of the field. The length, then, is 56 ft + 48 ft = 104 ft (since the length is 48 ft longer than the width).
So, the dimensions of the field are 104 feet by 56 feet

Describe how to translate the graph of g(x) = ln x into the graph of f(x)= ln (-5)+5
Answer:
B
Step-by-step explanation:
We know:
1. Replacing -x into x of an equations reflects the graph on the y-axis
2. If f(x) is a function, then f(x)+a is a vertically translated graph of the original graph, a units up
Looking at the original function of ln x and the transformed graph of ln(-x) +5, we see that we have replaced x with -x, which means it is a reflection across the y-axis.
Also, we have added a five after the function, so that means it is a vertical translation of 5 units up.
Looking at the answer choices, we see that B is the correct answer.

Ice cream in the shape of a sphere sits atop a cone as shown in the diagram below. Assume there is no ice cream inside the cone until after the ice cream melts. The diameter of the sphere and the diameter of the cone are both 4cm, and the height of the cone is 7.5 cm.
Part A: Determine whether the cone could contain all of the ice cream if it melted.
Part B: What would be the smallest cone in height in whole centimeters that would allow the cone to contain all of the melted ice cream if the diameter of the cone remains unchanged.
Part C: If the container of the ice cream changed to a cylinder as shown in the diagram below, what would be the smallest height of the cylinder needed to the nearest whole centimeter to contain the melted ice cream. Assume there is no ice cream n the cylinder before the ice cream melts. Please provide explanations so i can see where i messed up?
Answer:
Part A) The cone couldn't contain all the ice cream if it melted.
Part B) The height of the cone would be [tex]8\ cm[/tex]
Part C) The height of the cylinder would be [tex]3\ cm[/tex]
Step-by-step explanation:
Part A) Determine whether the cone could contain all of the ice cream if it melted
step 1
Find the volume of the ice cream (sphere)
The volume is equal to
[tex]V=\frac{4}{3}\pi r^{3}[/tex]
we have
[tex]r=4/2=2\ cm[/tex] -----> the radius is half the diameter
substitute
[tex]V=\frac{4}{3}\pi (2)^{3}=\frac{32}{3}\pi\ cm^{3}[/tex]
step 2
Find the volume of the cone
The volume is equal to
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
we have
[tex]r=4/2=2\ cm[/tex] -----> the radius is half the diameter
[tex]h=7.5\ cm[/tex]
substitute
[tex]V=\frac{1}{3}\pi (2)^{2}(7.5)=\frac{30}{3}\pi\ cm^{3}[/tex]
step 3
Compare the volume of the sphere and the volume of the cone
[tex]\frac{30}{3}\pi\ cm^{3} < \frac{32}{3}\pi\ cm^{3}[/tex]
The volume of the cone is less than the volume of the sphere
therefore
The cone couldn't contain all the ice cream if it melted.
Part B) What would be the smallest cone in height in whole centimeters that would allow the cone to contain all of the melted ice cream if the diameter of the cone remains unchanged
The volume of the cone is equal to
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
we have
[tex]V=\frac{32}{3}\pi\ cm^{3}[/tex]
[tex]r=2\ cm[/tex]
substitute in the formula and solve for h
[tex]\frac{32}{3}\pi=\frac{1}{3}\pi (2)^{2}h[/tex]
simplify

Part C) If the container of the ice cream changed to a cylinder as shown in the diagram below, what would be the smallest height of the cylinder needed to the nearest whole centimeter to contain the melted ice cream
The volume of the cylinder is equal to
[tex]V=\pi r^{2}h[/tex]
we have
[tex]V=\frac{32}{3}\pi\ cm^{3}[/tex]
[tex]r=2\ cm[/tex]
substitute in the formula and solve for h
[tex]\frac{32}{3}\pi=\pi (2)^{2}h[/tex]
simplify
[tex]\frac{32}{3}=(2)^{2}h[/tex]
[tex]\frac{32}{3}=4h[/tex]
[tex]h=\frac{32}{12}=2.67\ cm[/tex]
Round to the nearest whole centimeter
[tex]2.67=3\ cm[/tex]
Do you think this graph looks more like a quadratic or exponential function? Why do you think so?
Answer:
Exponential Function
Step-by-step explanation:
The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.
This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:
[tex]f(x)=f(0)(2)^{x}[/tex]
Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.

Step-by-step explanation:
Slaura walks 3/5 mile to school each day. Isaiah walk to school is 3 times as long as Slaura's. How far does Isaiah walk to school each day.
Answer:
1.8 miles
Step-by-step explanation:
3/5 * 3 for the extra mile that he walks
Answer:
1 4/5 miles to school. 3 3/5 miles if you wanted to know to school AND back.
Step-by-step explanation: You would take the 3/5 of a mile that Slaura walks every day and multiply it by 3. Your equation would be 3/5 x 3/1. Your answer for how many miles Isaiah walk to school everyday is 9/5 or 1 4/5 miles. If you wanted to know how many miles Isaiah walked to school AND back, then you would double 1 4/5 miles.
If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function". C = {(9, 1) (8, -3) (7, 5) (-5, 3)} Domain: {9, 8, 7, -5} Range: {1, -3, 5, 3} Domain: {1, -3, 5, 3} Range: {9, 8, 7, -5} not a function
Answer:
Domain: {9, 8, 7, -5}Range: {1, -3, 5, 3}Step-by-step explanation:
The function is a special relationship where each input has a single output.
We have C = {(9, 1); (8, -3); (7, 5); (-5, 3)}.
It's a function:
each values of x: 9, 8, 7, -5 has one value of y: 1, -3, 5, 3.
The doimain is set os x: {9, 8, 7, -5}.
The range is set of y: { 1, -3, 5, 3}.
F = {(x, y ) | x + y = 10}.
Domain: {10} Range: {10}
Emma is building a wall around her burning it has taken 45 minutes and she is 75% done what is the time it will take to finish building her wall
➷ 45 minutes is 3/4 of the total time
A simple way to do this is to find 1/4 of the time
To do this, divide by 3:
45/3 = 15
15 minutes is 1/4 of the time
To find the whole time, multiply this value by 4:
15 x 4 = 60
Subtract the time already passed from this:
60 - 45 = 15
It will take her 15 more minutes to finish building her wall.
