Una recta con pendiente -2 ´pasa por el punto P(5, -1). La abscisa del punto Q que está en esa recta es 1. Encuentre la ordenada de Q.
Answers
Answer:
La ordenada de Q es 7.
Step-by-step explanation:
La ecuación de una recta es:
y = a*x + b
donde a es la pendiente y b es la ordenada al origen.
Para este problema, sabemos que la pendiente es -2
Entonces:
a = -2
y = -2*x + b
También sabemos que esta recta pasa por el punto (5, -1)
Esto significa que cuando evaluamos la ecuación en x = 5, y toma el valor y = -1
Si reemplazamos esos valores en la ecuación, obtenemos:
-1 = -2*5 + b
-1 = -10 + b
-1 + 10 = b
9 = b
Entonces la ecuación de la recta es:
y = -2*x + 9
Sabemos que el punto Q está en la línea, y la abscisa de este punto es 1.
Entonces este punto es Q (1, k)
donde k es la ordenada de este punto.
Porque nuestra línea también pasa por este punto, podemos concluir que cuando x = 1, y = k
Reemplazando eso en la ecuación tenemos:
k = -2*1 + 9 = -2 + 9 = 7
k = 7
La ordenada de Q es 7.
Zeroes of a polynomial can be determined graphically. Number of zeroes of a polynomial is equal to number of points where the graph of polynomial.
2 points
a. intersects y-axis
b. intersects x-axis
c. intersects y-axis or intersects x-axis
d. none of these
Answers

Answer:
b. intersects x-axis
Step-by-step explanation:
A zero of the polynomial is where y = 0. The equation y = 0 is the equation of the x-axis, so intersections of the graph of the function with the x-axis are places where the function value is zero.
The number of (distinct real) zeros is equal to the number of points where the graph intersects the x-axis.
_____
Additional comment
When (x -p)^n is a factor of the polynomial, the graph will intersect the x-axis at x=p. The zero is said to have "multiplicity n". For odd values of n, the graph will cross the x-axis (change sign) at x=p. For even values of n, the graph will touch the axis at x=p, but will not cross there.
So, the number of intersections with the x-axis tells the number of distinct real zeros, but does not say anything about their multiplicity. Complex zeros will not cause the graph to touch the x-axis.
Round the greater number to the tens place. Then calculate the product.

Answers
The Answer Is Sin(B)=4/5
[tex] \sin( \beta ) = \frac{opposite}{hypotenuse} [/tex]
Meaning, sin(B)=4/5
Answer:
4/5
Step-by-step explanation:
The angle you want to look at is the one given to you with the beta symbol. The trigonometric funtion sin mean opposite/hypotenuse. The side that is opposite is stright across from ∠β which would be 4. The hypothenuse is the largest side of the triangle or the "slanted side of the triangle." With that explanation, the hypotenuse is 5.

The difference between two whole numbers is 99. The ratio of the two numbers is 2:5. What are the numbers?
Answers
Let the two whole numbers be 2x and 5x
The difference between 2x and 5x is 99. So,
5x-2x=99
3x=99
x=99/3

Therefore the two numbers are
5x=5*33=165
2x=2*33=66

A 16-inch diameter (8-inch radius) car tire is one of the most popular sizes for today's car Find the number of revolutions made by a tire with a radius of 8
inches that travels 5,280 feet (or 1 mile). Use 3.14 for Round your answer to the nearest tenth of a revolution.
Answers
Answer:
1261.1 revolutions
Step-by-step explanation:
Given
[tex]d = 16in[/tex] --- the diameter
[tex]Distance = 5280ft[/tex]
Required
The number of revolution completer
First, calculate the circumference (c) of the tire
[tex]c = \pi d[/tex]
[tex]c = 3.14 * 16[/tex]
[tex]c = 50.24[/tex]
Let the number of revolutions be n.
The product of n and the circumference equals to the total distance travelled.
So:
[tex]c * n = 5280 ft[/tex]
[tex]50.24in* n = 5280 ft[/tex]
Make n the subject
[tex]n = \frac{5280 ft}{50.24in}[/tex]
Convert feet to inch
[tex]n = \frac{5280 *12in}{50.24in}[/tex]
[tex]n = \frac{63360in}{50.24in}[/tex]
[tex]n = \frac{63360}{50.24}[/tex]
Solve for n
[tex]n = 1261.14649682[/tex]
Approximate
[tex]n = 1261.1[/tex]

us the f value and substitute for x.
1) f(1)= 1 - 5 = -4
2) f(-1) = -1 -5 = -6
3) f(2) = 2 - 5 = -3
4) f(0) = 0 - 5 = -5
