Distance between each pair of points is: 5.83
The distance formula, derived from the Pythagorean theorem, is used to find the distance between two points. You subtract and square the x-coordinates, do the same with the y-coordinates, sum those results, and take the square root of the sum to get the distance.
Explanation:The distance formula in mathematics is used to determine the distance between two points in a coordinate plane. The formula is derived from the Pythagorean theorem and is represented as D = √[(x2-x1)² + (y2-y1)²]. Let's say we have two points A1(x1, y1) and A2(x2, y2).
Firstly, subtract the x-coordinates (x2 and x1) and then square the result. Secondly, subtract the y-coordinates (y2 and y1) and then square the result. Finally, add the values obtained in the first and second steps to get the square of the distance. To find the actual distance, take the square root of this sum.The final result gives you the distance between the two points in the cartesian plane.

A box contains 3 plain pencils and 7 pens. A second box contains 4 color pencils and 4 crayons. One item from each box is chosen at random. What is the probability that a pen from the first box and a crayon from the second box are selected?
Answers
The first box has a total of 10 items ( 3 pencils + 7 pens = 10)
The probability of picking a pen would be 7/10
The second box has a total of 8 items ( 4 pencils + 4 crayons = 8)
The probability of picking a crayon would be 4/18, which reduces to 1/2
To find the probability of doing both, multiply each probability together:
7/10 x 1/2 = 7/20
The probability is 7/20
A birthday gift is wrapped in a cardboard box. The box measures 12 inches on each side. How many cubic inches will the box hold?
Answers
Answer:
1728 in³
Step-by-step explanation:
A 12-inch cube has a volume of (12 in)³ = 12³ in³ = 1728 in³.
The box will hold 1728 cubic inches.
To determine the volume of the box, which is the amount of space it can hold, one must calculate the product of its length, width, and height. Since the box measures 12 inches on each side, it is a cube. The volume ( V ) of a cube is given by the formula:
[tex]\[ V = a^3 \][/tex]
where a is the length of one side of the cube. In this case, a = 12 inches. Plugging this value into the formula, we get:
[tex]\[ V = 12^3 \] \[ V = 12 \times 12 \times 12 \] \[ V = 144 \times 12 \] \[ V = 1728 \][/tex]
Therefore, the volume of the box, or the number of cubic inches it will hold, is 1728 cubic inches.

Are independent events the same as mutually exclusive events? define your answer
Answers
Answer:
Two events are mutually exclusive if they can't both happen. Independent events are events where knowledge of the probability of one doesn't change the probability of the other. Two events are mutually exclusive when they cannot occur at the same time. For example, if we flip a coin it can only show a head OR a tail, not both. Independent event: The occurrence of one event does not affect the occurrence of the others.
Independent events do not affect each other's occurrence, while mutually exclusive events cannot occur at the same time. The concepts are distinct and significant in probability theory.
Independent vs Mutually Exclusive Events
Independent events and mutually exclusive events are not the same in probability theory. Two events are independent if the occurrence of one event does not affect the probability of the other event occurring. The mathematical representation of this is P(A AND B) = P(A)P(B). On the other hand, two events are mutually exclusive if they cannot occur at the same time, meaning the events do not share any outcomes and the probability of both events occurring together, P(A AND B), is zero.
An example of independent events might be rolling a dice and flipping a coin. Whether the dice shows a six does not affect whether the coin shows heads. An example of mutually exclusive events would be drawing a heart or a club from a deck of cards as a single card cannot be both a heart and a club.

Situation:
An archaelogist in Turkey discovers a

original amount of C-14.
N = Noekt
No = inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k = 0.0001
t = time, in years
FIND THE AGE OF THE SPEAR HEAD TO THE NEAREST YEAR
Answers
Answer:
t = 6162 years
Step-by-step explanation:
This equation takes the form of
[tex]N=N_{0}e^{kt}[/tex]
We are given everything but the amount of C-14 at time t = 0. But we can figure it out from the info we ARE given. We are told that when the spear head is found it contains 54% of its original amount of C-14. Notice we are dealing in percents. If 54% remains when it is found, it started out with 100% of its amount. That's our N value. Filling in:
[tex]100=54e^{.0001t}[/tex]
Our goal is to get that t down from the exponential position that it is currently in. To do that we will need to eventually take the natural log of both sides, because ln's and e's "undo" each other, much like squaring "undoes" a square, or dividing "undoes" multiplication. So we take the natural log of both sides. On the right side, notice that when we take the natural log, the e disappears; it's "undone", gone. Before that, though, we will simplify by dividing both sides by 54. 100/54 = 1.851851852. So, altogether...
[tex]ln(1.851851852)=.0001t[/tex]
Simplifying by plugging the log of that number into our calculator, we get
.6161861395 = .0001t and
t = 6161.8613

If = 3.52895, then the time is about 3 years and how many days?
Answers
Answer:
193
Step-by-step explanation:
We need to convert the decimal part of that number from years to days. Do that like this:
.52895 × [tex]\frac{365days}{1year}[/tex].
The year label cancels and we are left to multiply .52895 by 365 to get 193.06675 days.
Final answer:
3.52895 years is approximately 3 years and 193 days when converted, using the average number of days in a year (365.2422) to calculate the days from the fractional part of the year.
Explanation:
To calculate the time in years and days when given a decimal of years, one must convert the fractional part of the year into days. Assuming that the initial figure 'If = 3.52895' represents 3.52895 years, we would have 3 complete years and a fraction of a year (0.52895). To find the number of days in this fractional year, we need to multiply it by the average number of days in a year. The average year contains 365.2422 days, accounting for the additional leap year day every four years.
To convert the 0.52895 of a year to days, the calculation would be:
0.52895 × 365.2422 = 193.215 (approximately).
Therefore, 3.52895 years is roughly 3 years and 193 days.

The isosceles triangle has a perimeter of 7.5m. Which equation can be used to find the value of X if the shortest side,y, measures 2.1m? A. 2x-2.1=7.5 B. 4.2+y=7.5 C. y-4.2=7.5 D. 2.1+2x=7.5
Answers
Answer:
The equation can be used to find the value of x is 2.1 + 2x = 7.5 ⇒ D
Step-by-step explanation:
* Lets talk about the isosceles triangle
- The isosceles triangle has two equal sides
- The angle between the two equal sides is called the vertex angle
- The side opposite to the vertex angle is called the base of the triangle
- The end vertices of the base are called the base angles
- The two base angles are equal in measure
- The perimeter of any triangle is the sum of the length of its
three sides
* Lets solve the problem
∵ The triangle is isosceles triangle
- The shortest side is opposite to the shortest angle
∵ The two base angles are equal in measure
∴ The shortest angle is the vertex angle which opposite to the
base of the triangle
∴ The shortest side is the base of the triangle
∵ The length of the shortest side is y
∴ The length of the equal sides is x
∴ The lengths of the sides of the triangles are x , x , y
- The perimeter of the triangle is the sum of the length of its
three sides
∴ The perimeter of the triangle = x + x + y
∵ The perimeter of the triangle is 7.5 m
∴ x + x + y = 7.5 ⇒ add the like terms
∴ 2x + y = 7.5
∵ y = 2.1 ⇒ given
∴ 2x + 2.1 = 7.5
∴ 2.1 + 2x = 7.5
* The equation can be used to find the value of x is 2.1 + 2x = 7.5

Step-by-step explanation:
The 3 angles on the right form a straight angle, thus they sum to 180°
Subtract the 2 given angles from 180 to find measure of third angle ( which is the angle inside the triangle )
third angle = 180° - (70 + 60)° = 180° - 130° = 50°
The sum of the 3 angles in a triangle = 180°
Subtract the 2 known angles from 180 for measure of x

Answer:
The surface area of the composite figure = 1172.08 inches²
Step-by-step explanation:
* Lets explain the figure
- There is a cylinder with diameter 8 inches and height 9 inches
- Rectangular prism with dimensions 16 , 11 , 11 inches
- The surface area of the cylinder will be the curved area and the
top base
- The surface area of the prism will be the surface area of one base ,
four side faces and top face which is the remaining from the subtraction
of the rectangular base and the circular base
* Lets solve the problem
# The surface area of the cylinder
∵ The diameter of the base of the cylinder is 8 inches
∵ The diameter = twice the radius
∴ 8 = 2r ⇒ divide both sides by 2
∴ r = 4 inches
∵ The area of the circle = πr²
∴ The area of the base = π(4)² = 16π inches²
∵ π = 3.14
∴ The area of the base = 16(3.14) = 50.24 inches²
∵ The area of the curved surface = 2πrh
∵ r = 4 inches and h = 9 inches
∴ The area of the curved surface = 2(3.14)(4)(9) = 226.08 inches²
∴ The surface area of the cylinder = 226.08 + 50.24 = 276.32 inches²
# The surface area of the rectangular prism
∵ The dimensions of its base are 16 and 11 inches
∵ The area of the rectangle = length × width
∴ The area of the lower base = 16 × 11 = 176 inches²
∵ The area of the top face = area of the rectangle - area of the circle
∵ The area of the rectangle = 176 inches²
∵ The area of the circle = 50.24
∴ The area of the top face = 176 - 50.24 = 125.76 inches²
- There are two side faces with dimensions 16 and 11 inches
∴ The area of the two faces = 2 × 16 × 11 = 352 inches²
- There are two faces with dimensions 11 and 11 inches
∴ The area of the two faces = 2 × 11 × 11 = 242 inches²
∵ The surface area of the rectangular prism is the sum of the 6 faces
∴ The surface area of the prism = 176 + 125.76 + 352 + 242
∴ The surface area of the prism = 895.76 inches²
- The surface area of the composite figure is the sum of the surface
area of the cylinder and the surface area of the prism
∵ The surface area of the cylinder = 276.32 inches²
∵ The surface area of the prism = 895.76 inches²
∴ The surface area of the composite figure = 276.32 + 895.76
∴ The surface area of the composite figure = 1172.08 inches²

Answer:
Doug's garden: 87 lbsKelsey's garden: 15 lbsStep-by-step explanation:
Let k represent the pounds of produce coming from Kelsey's garden. Then Doug's garden produces 5.8k pounds of produce, and the total weight of it is ...
k + 5.8k = 102
6.8k = 102 . . . . . . . . . . . simplify
k = 102/6.8 = 15 . . . . . . pounds of produce from Kelsey's garden
5.8k = 5.8·15 = 87 . . . . pounds of produce from Doug's garden
D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. What is m∠DEF? A. 30° B. 45° C. 60° D. 90°
Answers
Answer:
Option D. 90°
Step-by-step explanation:
we have
[tex]D(5, 7),E(4, 3),F(8, 2)[/tex]
Plot the vertices
see the attached figure
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
step 1
Find the distance DE
[tex]D(5, 7),E(4, 3)[/tex]
substitute
[tex]d=\sqrt{(3-7)^{2}+(4-5)^{2}}[/tex]
[tex]d=\sqrt{(-4)^{2}+(-1)^{2}}[/tex]
[tex]DE=\sqrt{17}\ units[/tex]
step 2
Find the distance EF
[tex]E(4, 3),F(8, 2)[/tex]
substitute
[tex]d=\sqrt{(2-3)^{2}+(8-4)^{2}}[/tex]
[tex]d=\sqrt{(-1)^{2}+(4)^{2}}[/tex]
[tex]EF=\sqrt{17}\ units[/tex]
step 3
Find the distance DF
[tex]D(5, 7),F(8, 2)[/tex]
substitute
[tex]d=\sqrt{(2-7)^{2}+(8-5)^{2}}[/tex]
[tex]d=\sqrt{(-5)^{2}+(3)^{2}}[/tex]
[tex]DF=\sqrt{34}\ units[/tex]
step 4
The triangle DEF is a right triangle because satisfy the Pythagoras theorem
so
[tex](\sqrt{34})^{2}=(\sqrt{17})^{2}+(\sqrt{17})^{2}[/tex]
[tex]34=34[/tex] -----> is true
therefore
The measure of angle DEF is a right angle
Can you use the Distributive Property to write the formula P = ( 2 x l ) + ( 2 x w ) another way? Explain.
Answers
Answer:
Step-by-step explanation:
Please avoid use of " x " to indicate multiplication; instead, use " * " or " · "
P = ( 2 x l ) + ( 2 x w ) comes out as P = ( 2 * l ) + ( 2 * w ).
This could be written in several different ways, e. g.,
P = ( 2 * l ) + ( 2 * w ),
P = ( 2 * w ) + ( 2 * l ),
P = ( l * 2 ) + ( w * 2), and so on.
The Distributive Property permits us to rewrite the formula P = (2 x l) + (2 x w) as P = 2(l + w). This factorization is an alternative mathematical representation of the same calculation.
Explanation:Yes, you can utilize the Distributive Property to rewrite the formula P = (2 x l) + (2 x w) in a different way. The Distributive Property in mathematics is a fundamental property that states a(b + c) = ab + ac, which means you can distribute multiplication over addition. Applying this property to the formula P = 2l + 2w, we can factor out a common factor of 2 from both terms. So the formula can be written equivalently as P = 2(l + w).
