help ASAP show the work, no links pleaseee
Answer:
x = 28
Step-by-step explanation:
AB= AC
∠B = ∠C {Angles opposite to equal sides are equal}
∠A + ∠B + ∠C = 180 {angle sum property}
3x + x + 20 + x + 20 = 180 {Combine like terms}
3x +x +x + 20 + 20 = 180
5x + 40 = 180 {subtract 40 from both sides}
5x = 180 - 40
5x = 140 {divide both sides by 5}
x = 140/5
x = 28

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.
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.
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.
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]
Pls I need help someone pls help me
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
9514 1404 393
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.

Find the distance between the two points.
Answer:
[tex]\sqrt{61}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 2,- 4) and (x₂, y₂ ) = (4, 1)
d = [tex]\sqrt{(4-(-2))^2+(1-(-4))^2}[/tex]
= [tex]\sqrt{(4+2)^2+(1+4)^2}[/tex]
= [tex]\sqrt{6^2+5^2}[/tex]
= [tex]\sqrt{36+25}[/tex]
= [tex]\sqrt{61}[/tex]

If all three sides of a triangle have length x, what is the perimeter of the triangle?
A. x/3
B. x + x + x + x
C. 3x
D. 3 + x
Answer:
C) 3x
Step-by-step explanation:
Perimeter can be defined as side a + side b + side c,
since all sides are x we have
x + x + x = 3x

The difference between two whole numbers is 99. The ratio of the two numbers is 2:5. What are the numbers?
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
x=33
Therefore the two numbers are
5x=5*33=165
2x=2*33=66
Answer:
28:71
Step-by-step explanation:
99/7=14.14285714 (make sure to keep that in the calculator) that equals 1 part.
Therefore,
2×14.14...=28 (round up to nearest whole number)
5×14.14..=71 (round up to nearest whole number)

Step-by-step explanation:
Given
The expression is
[tex](\dfrac{4d}{5}-7e)^2[/tex]
Use identity [tex](a-b)^2=a^2+b^2-2ab[/tex]
Apply identity
[tex]\Rightarrow \left( \dfrac{4d}{5}-7e\right)^2=\left( \dfrac{4d}{5}\right)^2+(7e)^2-2\times \left( \dfrac{4d}{5}\right)(7e)\\\\\Rightarrow \left( \dfrac{4d}{5}-7e\right)^2=\dfrac{16d^2}{25}+49e^2-\dfrac{56de}{5}[/tex]
