Answers
Answer:
see below
Step-by-step explanation:
We have two points, so we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -6- -6)/( 6-3)
= ( -6+6)/( 6-3)
= 0/3
= 0
The slope is zero
This means that it is a horizontal line ( the y value does not change)
Answer:
slope is 0, line is horizontal
Step-by-step explanation:
First we will have to find the slope
Slope is equal to: y2-y1/x2-x1 (rise/run)
So let's label the points
(3,-6), (6, -6)
x1=3
y1=-6
x2=6
y=-6
now plug those into the equation
-6-(-6)/6-3= 0/3=0
since the slope is equal to 0, that means the line is horizontal

2x² + 10 factorización
Answers
Answer:
2(x² + 5)
Step-by-step explanation:
To factor 2x² + 10, we can first factor out the greatest common factor of the terms, which is 2:
2x² + 10 = 2(x² + 5)
We can't factor anymore, so the answer is:
2(x² + 5)
Answer:
2(x² + 5)
Step-by-step explanation:
To factorise this, do the distributive property backwards. In other words:
2x² + 10
2x² ÷ 2 + 10 ÷ 2
x² + 5
2(x² + 5)
∴ 2(x² + 5) is the answer

Step-by-step explanation:
The square of the distance from a point on the ellipse to the point (1, 0) is ...
d^2 = (x -1)^2 +y^2
Using the equation of the ellipse to write an expression for y^2, we have ...
d^2 = (x -1)^2 +5 -5x^2

The mean distance of the earth from the sun (let's call it d) is 93 million miles. The distance varies as much as 1.6 million miles. Write the equation that describes the possible distances of the earth from the sun, using as distance unit millions of miles.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Mean distance of earth from the sun = 93 million miles
Let mean distance of earth from the sun = d
The variation on the distance is as much as 1. 6 million miles
Possible distances of the earth from the sun can be modeled using :
|d - 93| = ± 1.6
Where d = distance from earth to the sun
d = - 1.6 million + 93 million
d = 91.4 million
d = 1.6 million + 93 million
d = 94.6 million
Hence, possible distance from earth to the sun :
91.4 < d < 94.6

2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 2 as the denominator :

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Here's how:
-9•(h-16)
————————— • 2 = 0 • 2

Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-9 • (h-16) = 0
Equations which are never true:
4.2 Solve : -9 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.3 Solve : h-16 = 0
Add 16 to both sides of the equation :

A and B will take the same 10-question examination. Each question will be answered correctly by A with probability .7, independently of her results on other questions. Each question will be answered correctly by B with probability .4, independently both of her results on the other questions and on the performance of A. (a) Find the expected number of questions that are answered correctly by both A and B. (b) Find the variance of the number of questions that are answered correctly by either A or B.
Answers
(a) The expected number of questions answered correctly by both A and B is 28.
(b) The variance of the number of questions answered correctly by either A or B is 4.5.
Let's define the following variables:
X = Number of questions answered correctly by A
Y = Number of questions answered correctly by B
(a) Expected number of questions answered correctly by both A and B:
We can use the formula for the expected value of the product of two independent random variables:
E(X × Y) = E(X) × E(Y)
The probability of A answering a question correctly is 0.7, and the probability of B answering a question correctly is 0.4.
Since the questions are independent, we can calculate the expected values for X and Y:
E(X) = 10 (number of questions) × 0.7 (probability of A answering correctly) = 7
E(Y) = 10 (number of questions) × 0.4 (probability of B answering correctly) = 4
Now, the expected number of questions answered correctly by both A and B is:
E(X× Y) = E(X) × E(Y)
= 7×4
= 28
(b) Variance of the number of questions answered correctly by either A or B:
Variance is calculated differently for independent events. Since A and B's performances are independent, we can use the following formula:
Var(X + Y) = Var(X) + Var(Y)
The variance of a binomial distribution with n trials and probability p of success is given by np(1-p).
For A and B:
Var(X) = 10× 0.7 × (1 - 0.7)
= 2.1
Var(Y) = 10 × 0.4× (1 - 0.4)
= 2.4
Now, the variance of the number of questions answered correctly by either A or B is:
Var(X + Y) = Var(X) + Var(Y)
= 2.1 + 2.4
= 4.5

Geometric definition of circle: a circle is the set of all points (x,y) in a plane (________) that are equidistant (_________) from a fixed point called the focus which also is the center of the circle
Answers
A circle is defined geometrically as the set of all points (x, y) in a two-dimensional plane that are equidistant from a fixed point called the center of the circle.
In other words, for any point (x, y) on the circle, the distance between that point and the center is constant.
To elaborate, let's consider a circle with center (h, k) and radius r. Any point (x, y) lying on the circle satisfies the equation of distance as follows:
√((x - h)² + (y - k)²) = r
This equation represents the Pythagorean theorem applied to the right triangle formed by the distance between the point (x, y) and the center (h, k), with the hypotenuse being the radius r. Since all points on the circle have the same distance from the center, this equation holds true for any point on the circle.
The constant distance, or radius, is the key characteristic of a circle. It determines the size of the circle and is defined as the distance from the center to any point on the circumference. The radius is typically denoted by the lowercase letter "r" and can be used to calculate various properties of the circle, such as its area and circumference.
In summary, a circle is the set of all points in a plane that are equidistant from a fixed point called the center. The distance between any point on the circle and the center is constant, and this distance is defined as the radius of the circle. The geometric definition provides a clear understanding of the fundamental properties and characteristics of a circle.
