Determine if (6, 2) is a solution to the system of equations.
2x + y = 10
3x + 2y = 10
Answer:
no
Step-by-step explanation:
plug 6 in for x and 2 in for y, as (x, y) = (6, 2)
first equation:
y = 1 * y
2(6) + 1(2) = 10
12 + 2 = 10
14 = 10
this is false
second equation:
3(6) + 2(2) = 10
18 + 4 = 10
22 = 10
this is false
for this to be a solution, it must fit into both equations. as this fits into neither, this is not a solution

The gravitational force ona abody falling towards the earthb is directly proportional to the mass of the body the gravitiaional force on the body js 2 kg is 19.6 newtons
A. Write a direct variation equation relating the mass x and the gravitational force y on the falling body
B. Using your equation from 4.a find the gravitaional force of an object with the mass of 5kg
Don't RIP OFF OR I WILL REPORT
Answer:
A. y = 9.8xB. 49 NewtonsStep-by-step explanation:
Direct proportional relationship formula
y = kx, where y- dependent variable, x- independent variable, k- coefficient of proportionalityGiven values
x = 2 kgy = 19.6 NFind the value of k using the formula
19.6 = 2kk = 19.6/2k = 9.8Part AThe equation for this case is
y = 9.8xPart BFind the value of y when x = 5
y = 9.8*5 = 49 NAnswer:
A. y = 9.8x
B. 49 newtons
Step-by-step explanation:
Part A
Definition of the given variables:
x = mass in kgy = gravitational force in newtonsIf the gravitational force is directly proportional to the mass, then:
[tex]y \propto x \implies y=kx \quad \textsf{(for some constant k)}[/tex]
Given:
x = 2 kgy = 19.6 newtonsSubstitute the given values into the equation and solve for k:

Therefore, the direct variation equation is: [tex]y=9.8x[/tex]
Part B
To find the gravitational force of an object with mass of 5 kg, substitute x = 5 into the found equation from part A and solve for y:

There is a “family” of Z distributions?
Reason:
There is only one Z distribution, which is also known as the standard normal distribution. This distribution has a mean of mu = 0 and a standard deviation of sigma = 1. So unless you consider a family to only have one member, then I'd consider the statement your teacher gave you to be false.
On the other hand, if we were talking about the student T distribution, then this is a family of function curves. The reason being is that the degrees of freedom (df) will change the shape of said curve. The value of df will depend on the sample size n. Recall that df = n-1. As n gets larger, then the T distribution curves will slowly start to look like the Z distribution. For n > 30, the difference is so very minor that it's easier to swap over to the Z distribution even if you don't know sigma.
In other words, there is a family of T distribution curves in which slowly approach to mimicking the Z distribution curve when n is large (usually n > 30).

Area = 11 x 11Area = 121 m²Given f (x)= x-4/x^2+13x+36, which of the following is true? f(x) is decreasing for all x > –9 f(x) is increasing for all x < –9 f(x) is increasing for all x > –4 f(x) is decreasing for all x > –4
The simplified expression of the function [tex]f (x)= \frac{x-4}{x^2+13x+36}[/tex] is
[tex]f (x)= \frac{x-4}{(x+9)(x+4)}[/tex]. f(x) is increasing for all x > –4
What is a function?A function is defined as a relation between the set of inputs having exactly one output each.
The function expression is given as:
[tex]f (x)= \frac{x-4}{x^2+13x+36}[/tex]
Expand the denominator
[tex]f (x)= \frac{x-4}{x^2+4x+9x+36}[/tex]
Factorize the denominator
[tex]f (x)= \frac{x-4}{x(x+4)+9(x+4)}[/tex]
Factor out x + 9
[tex]f (x)= \frac{x-4}{(x+9)(x+4)}[/tex]
Hence, the simplified expression of the function [tex]f (x)= \frac{x-4}{x^2+13x+36}[/tex] is
[tex]f (x)= \frac{x-4}{(x+9)(x+4)}[/tex]. f(x) is increasing for all x > –4

In a field of wildflowers, the number of flowers is decaying exponentially. One year there are 1,200 flowers, and the next year there are 900 flowers.
The percent of decrease is 33 25 30 20 and the decay factor is 0.75 1.25 0.67 0.70
Find the amount of decay:
1200 - 900 = 300
Divide amount of decay by original amount:
300/1200 = 0.25
The percent of decay is 25 %
The decay factor is 1.00 a 0.25 = 0.75

Which of the following statements about the expected value of a random experiment is true? A. The expected value is the value you will get after one trial. B. The expected value is the average of the values after 100 trials. C. As the number of trials gets larger, the average of the trials approaches the expected value. D. The expected value never actually equals the average of the trials. Please select the best answer from the choices provided A B C D
Answer: C. As the number of trials gets larger, the average of the trials approaches the expected value
Step-by-step explanation:
The expected value is the weighted average of the results of an experiment. As more trials go on, the actual average is more likely to get closer to the expected value. The expected value can be explained as the theoretical result after infinity trials, so as the number of trials approaches infinity, the result will approach the expected value.

A circle with a centre 0, has an equation x2 + y2 = 25
The coordinate A (4,3) is on the circumference of the circle.
Find the equation of the tangent at point A.
The linear equation of the tangent at point A is given by:
[tex]y = \frac{-4x + 25}{3}[/tex]
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, to find the slope, we need to find the derivative at (4,3), using implicit differentiation. Hence:
[tex]2x\frac{dx}{dx} + 2y\frac{dy}{dx} = 0[/tex]
[tex]\frac{dy}{dx} = -\frac{x}{y}[/tex]
[tex]\frac{dy}{dx} = -\frac{4}{3}[/tex]
Then:
[tex]y = -\frac{4}{3}x + b[/tex]
We use point (4,3) to find b, hence:
[tex]y = -\frac{4}{3}x + b[/tex]
[tex]3 = -\frac{16}{3} + b[/tex]
[tex]b = \frac{25}{3}[/tex]
Hence, the equation is:
[tex]y = \frac{-4x + 25}{3}[/tex]
