1012El cateto más corto de un triangulo rectángulo es 9m más corto que la hipotenusa y 7m más corto que el cateto adyacente. Calcula el área de dicho triangulo, ayuda plis. Jijijiji
Resolviendo una ecuación cuadratica encontraremos los catetos del triangulo, y con eso veremos que el area es:
A = 60.92m²
¿Como encontrar el area del triangulo?
Para un triangulo rectangulo podemos definir:
x = cateto corto.y = cateto largoh = hipotenusa.Por el teorema de Pitagoras sabemos que:
x² + y² = h²
Y el area se escribe como:
A = x*y/2
Sabemos que:
x = h - 9m
x = y - 7m
Entonces:
h = x + 9m
y = x + 7m
Reemplazando eso en la ecuacion de Pitagoras:
x² + y² = h²
x² + (x + 7m)² = (x + 9m)²
x² + x² + 14m*x + 48m² = x² + 18m*x + 81m²
x² + x² - x² + 14m*x - 18m*x + 48m² - 81m² = 0
x² - 4m*x - 33m² = 0
las soluciones de la ecuación cuadratica son:
x = (4m ± √( (4m)² - 4*1*(-33m²))/(2)
x = (4m ± 12.16m)/2
Solo nos importa la solución positiva:
x = (4m + 12.16m)/2 = 8.08m
Entonces el otro cateto mide:
y = 8.08m + 7m = 15.08m
Y el area del triangulo será:
A = (8.08m)*(15.08m)/2 = 60.92m²

A rectangular box which i open at the top can be made from an 12-by-30-inch piece of metal by cutting a quare from each corner and bending up the ide. Find the dimenion of the box with greatet volume, where h = height, l = length, and w = width. (Note: let the width be determined by the 12-inch ide and the length by the 30-inch ide. )
The dimension of the box with greatest volume is h = 2.64 in, l = 24.72 in, and w = 6.72 in.
If squares of equal sizes are to be cut out from the four corners so the four sides can be bent upwards, then the length of these squares will be the height of the box. Also twice of this length subtracted from the initial length and width of the material will be the new length and width of the box, respectively.
let x = length of square to be cut = height of the box
length of the box = 30 - 2x
width of the box = 12 - 2x
The volume of the box, which is a rectangular prism, is the product of the length, height and width.
V = l x w x h
V = (30 - 2x)(12 - 2x)(x)
V = 360x - 84x² + 4x³
To obtain the largest volume possible, the first derivative of the volume should be equal to zero.
V'(x) = 0
V = 360x - 84x² + 4x³
360 - 168x + 12x² = 0
Simplify and solve for the value of x.
360 - 168x + 12x² = 0
x² - 14x + 30 = 0
x = 7 ± √19
x₁ = 11.35
x₂ = 2.64
Check each value.
When x = 11.35 = h
l = 30 - 2x = 7.3
w = 12 - 2x = -10.7 (dimension should be positive)
When x = 2.64 = h
l = 30 - 2x = 24.72
w = 14 - 2x = 6.72
Hence, the length of square to be cut is 2.64 in.

Make your angle measures correct to the nearest degree and side measures to 1 decimal place
The measure of angle Z is 34°, side length of YZ is 34.1, and the side length of XZ is 41.1. The correct option is the third option ∠Z = 34°, YZ = 34.1, XZ = 41.1
Calculating measures of angles and side measures of a triangleFrom the question, we are to determine the angles measures of and the side measures of the given triangle XYZ
From the given information,
∠Y = 90°
XY = 23
∠X = 56°
First, we will determine the measure of angle Z
m ∠X + m ∠Y + m ∠Z = 180° (Sum of angles in triangle)
56° + 90° + m ∠Z = 180°
m ∠Z = 180° - 56° - 90°
m ∠Z = 34°
Now, since the measure of one of the angles is 90°, ΔXYZ is a right triangle.
Thus,
From SOH CAH TOA, we can write that
tan X = |YZ| / |XY|
∴ tan 56° = |YZ| / 23
|YZ| = 23 × tan 56°
|YZ| = 34.0989
|YZ| ≈ 34.1
Also,
cos X = |XY| / |XZ|
cos 56° = 23 / |XZ|
|XZ| = 23 ÷ cos 56°
|XZ| = 41.1307
|XZ| ≈ 41.1
Hence, ∠Z = 34°, |YZ| = 34.1, and |XZ| = 41.1

How much do you share on social media? Do you have accounts linked to your computer, phone, and tablet? The average teen spends around five hours per day online, and checks his or her social media account about 10 times each day.
When an image or post is shared publicly, some students are surprised at how quickly their information travels across the internet. The scary part is that nothing online is really private. All it takes is one friend sharing your photo or updates with the public to create a very public viral trend.
For this project, you will use what you have learned about exponential functions to study what happens if a social media post is shared publicly.
Social Sharing
Three Algebra 1 students are comparing how fast their social media posts have spread. Their results are shown in the following table:
Student Amber Ben Carter
Description Amber shared her photo with 3 people. They continued to share it, so the number of shares increases every day, as shown by the function. Ben shared his post with 2 friends. Each of those friends shares with 3 more every day, so the number of shares triples every day. Carter shared his post with 10 friends, who each share with only 2 people each day.
Social Media Post Shares f(x) = 3(4)x
Day Number of Shares
0 2
1 6
2 18 Carter shared his post with 10 friends, who each share with only 2 people each day.
Write an exponential function to represent the spread of Ben's social media post.
Write an exponential function to represent the spread of Carter's social media post.
Graph each function using at least three points for each curve. All graphs should be placed together on the same coordinate plane, so be sure to label each curve. You may graph your equation by hand on a piece of paper and scan your work, or you may use graphing technology.
Using the functions for each student, predict how many shares each student's post will be received on Day 3 and then on Day 10. Justify your answers.
If Amber decides to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, the new function representing her photo shares is f(x) = 3(4)x + 45. How does this graph compare with the original graph of Amber's photo share?
Based on your results, which student's post travels the fastest? How is this shown in the equation form of the functions?
If you had to choose, would you prefer a post with fewer friends initially but more shares, like Amber, or more friends initially but fewer shares? Justify your answer with your calculations from previous questions.
1) Exponential function to show the spread of Ben' s social media post is
y = 2(3)ˣ.
2) Exponential function to represent the spread of Carter's social media post is y = 10(2)ˣ.
Define exponential function.The mathematical expression f(x)=exp or ex denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras. When b > 0 and b 1, an exponential function has the form f(x) = bˣ. The base is b, and the exponent is x, just like in any exponential expression. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.
Given,
1) Exponential function to show the spread of Ben' s social media post:
y = 2(3)ˣ
2) Exponential function to represent the spread of Carter's social media post:

Scatterplot D; r = 0.86
How to interpret the correlation coefficient?The correlation coefficient is defined as a statistical measure of the strength of a linear relationship that exists between two variables. Its' values can range from -1 to 1.
Now, a correlation is considered to be a positive correlation when both variables increases or decreases in tandem which is the same direction. Meanwhile, a negative correlation is defined as on whereby one variable increases as the other decreases.
Now, the farther away the data points are from each other the greater the value of the correlation coefficient and vice versa.
The scatterplot A is a negative correlation because the output increases as the input decreases and vice versa. This is more scattered than the other negative correlation; r = -0.42
The scatterplot B also has a stronger negative correlation than scatter plot A since r = -0.85
The scatterplot C has a positive correlation, but not so strong as seen by the spacing of the scatter dot points. Thus, the scatterplot C has a correlation coefficient of r = 0.64
The scatterplot D has a stronger positive correlation coefficient than C as seen in the dot scatter points and as such its' correlation coefficient is 0.86

We have to explain how a number line can be used to compare two negative integers.
Integers are whole numbers they can be negative whole numbers or positive whole numbers for example 2, 4, 1, -8, 0, etc.
Plot the negative integers on a number line. It will be smaller than the other number if it is further to the left.
The numbers always go up (become "more positive") to the right and down (become "more negative") to the left on a number line. Numbers to the right are bigger than numbers to the left, and the opposite is true the other way around.
Thus, on a number line, plot the negative integers. The number that is further to the left will be less than the other.

Excel's binom.dist function can be used to compute both binomial probabilities and cumulative binomial probabilities
The Excel BINOM.DIST function returns the individual term binomial distribution probability. You can use BINOM.DIST to calculate probabilities that an event will occur a certain number of times in a given number of trials. BINOM.DIST returns probability as a decimal number between 0 and 1.
We use BINOM.DIST in problems with a fixed number of tests or trials, when the outcomes of any trial are only success or failure, when trials are independent, and when the probability of success is constant throughout the experiment.
For example, BINOM.DIST can calculate the probability that two of the next three babies born are male.

Find the value of r so the line that passes through the pair of points has the given slope.
(12, 10), (−2, r), m=−4
Based on the concept of the slope intercept form, the value of r is 66.
Slope intercept form:
The general formula to calculate the slope intercept form equation is written as,
y = mx + c
where
(x, y) represents the point
m represents the slope
c represents the y-intercept.
Given,
Here we know the pair of points (12, 10), (−2, r) and the value of slope which is m = -4.
And we need to find the value of r.
We know that the formula for of the slope intercept form is
y = mx + c
So, we have to use the slope and the point (12, 10), to find the intercept of the line,
When we apply the value on the formula, then we get,
=> 10 = -4(12) + c
=> 10 = -48 + c
=> c = 58
Therefore, the slope intercept form equation is written as
=> y = -4x + 58
Now, we have to find the value of r, by apply the point (-2,r) on the equation, then we get,
=> r = -4(-2) + 58
=> r = 8 + 58
=>r = 66
Therefore, the value of r for the given pair of points is 66.

Line g pae through point (9, 9) and (1, 4). Line h i parallel to line g. What i the lope of line h?
Line g pae through point (9, 9) and (1, 4) and the slope of line h is 0.68.
The coordinates of line g are (9,9) and (1,4).
Substitute the values in the slope formula with (x1, y1) = (9,9) and (x2, y2) = (1, 4).
m = (y2-y1)/(x2-x1)
m = (4-9)/ (1-9)
m = (-5)/ (-8)
m = 0.68
the slope of the line g is 0.68
line h is parallel to line g so parallel lines have the same slope
slope of line h is 0.68

A bag contains 5 red marbles, 7 blue marbles and 2 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 1000th, that both
marbles drawn will be blue?
The probability that both marbles drawn will be blue is 0.218.
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.
Since there are 7 blue marbles in the bag.
The first blue marble drawing likelihood is 7/15.
The second blue stone has a 7/15 chance of being drawn.
The likelihood that both marbles are chosen will be blue is equal to 7/15*7/15,
= 49/225,
=0.218
Hence the probability of that both marbles drawn will be blue is =0.218
