Answer:
2/3 or -5 is correct for all future users.
Step-by-step explanation:
The roots of the quadratic equations or the values of x are -5 and 2/3.
What is a quadratic equation?A quadratic equation is an algebraic equation of degree two. An algebraic equation of degree n has exactly n number of roots.
Given a quadratic equation 3x² + 13x = 10 which can be written as,
3x² + 13x - 10 = 0.
Now two numbers that add to 13 and multiplied to -30 are 15 and - 2.
3x² + 15x - 2x - 10 = 0.
3x(x + 5) - 2(x + 5) = 0.
(x+5)(3x-2) = 0.
x + 5 = 0 OR 3x -2 = 0.
x = -5 OR x = 2/3.

What is the average rate of change of the line whose equation is:
y−3=−12(x+4)?
PLEASE HELPPPP
Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12

Step-by-step explanation:
We know that to find the radius, we divide the diameter by 2, so the first one is correct.We know that the second one is incorrect because we just said that we would divide the diameter by 2 for the radius, so we would multiply the radius by 2 to find the diameter.The third statement is correct because the circumference is approximately 3 times bigger than the diameter.The fourth statement is correct because the circumference is equal to pi times 2 times the radius.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

El radio medio de la Luna es 1737 km, el de la Tierra es de 6,371 · 106 m, y el del Sol es de 6,96 · 105 km. a. ¿Cuántas veces es mayor el radio de la Tierra que el de la Luna? b. ¿Cuántas veces es mayor el diámetro del Sol que de la Tierra? c. ¿Cuántas veces es mayor el diámetro del Sol que el de la Luna?
Answer:
a) El radio de la Tierra es 3.668 veces mayor que el radio de la Luna.
b) El radio del Sol es 109.245 veces mayor que el radio de la Tierra.
c) El radio del Sol es 400.711 veces mayor que el radio de la Luna.
Step-by-step explanation:
a) ¿Cuántas veces es mayor el radio de la Tierra que el de la Luna?
En esta pregunta nos piden la razón del radio medio de la Tierra al radio medio de la Luna. Las unidades están en kilómetros:
[tex]r = \frac{6.371\times 10^{3}\,km}{1.737\times 10^{3}\,km}[/tex]
[tex]r = 3.668[/tex]
El radio de la Tierra es 3.668 veces mayor que el radio de la Luna.
b) ¿Cuántas veces es mayor el diámetro del Sol que de la Tierra?
El diámetro equivale a dos veces el radio, por tanto, se puede utilizar la relación de radios para determinar la razón, definida en este caso como la razón del radio medio del Sol al radio medio de la Tierra. Las unidades están dadas en kilómetros:
[tex]r= \frac{6.96\times 10^{5}\,km}{6.371\times 10^{3}\,km}[/tex]
[tex]r = 109.245[/tex]
El radio del Sol es 109.245 veces mayor que el radio de la Tierra.
c) ¿Cuántas veces es mayor el diámetro del Sol que el de la Luna?
El diámetro equivale a dos veces el radio, por tanto, se puede utilizar la relación de radios para determinar la razón. Una forma sintética de obtener la razón consiste en obtener el producto de las razones encontradas en a) y b). Es decir:
[tex]r = 3.668\times 109.245[/tex]
[tex]r = 400.711[/tex]
El radio del Sol es 400.711 veces mayor que el radio de la Luna.

On a plane, 2/5 of the passengers were British. 30% of the British passengers were men. There were 36 British men on the plane. Find the total number of passengers on the plane
Answer:
76 passengers
Step-by-step explanation:
100-36 is 64 and that makes 64 + 36 =100-30 is 70% and we have 36 + 40 =76
There were 300 passengers.
What is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
Given:
Fraction of British = 2/5
Percent of British men = 30%
Number of British men = 36
let the British passenger be x
30 /100 * x= 36
x=120
and let the total passenger by y
2/5 of y = 120
y= 120 * 5/2
x= 300
Hence, there were 300 passengers.

Complete question :
Simba Travel Agency arranges trips for climbing Mount Kilimanjaro. For each trip, they charge an initial fee of $100 dollars, in addition to a constant fee for each vertical meter climbed. For instance, the price for climbing to the Shira Volcanic Cone, which is 3000 meters above the base of the mountain, is $400 dollars. Let F(d) denote the fee of a trip F (measured in dollars) as a function of the vertical distance climbed d (measured in meters). Write the function's formula.
Answer:
F(d) = $100 + $0.1d
Step-by-step explanation:
Given the following :
Total Cost of mountain climbing :
Initial fee + constant fee per vertical meter climbed
Initial fee = $100
Total cost of climbing the Shira volcanic cone = $400
Height of Shira volcanic cone = 3000 m
The fee of a trip ; F(d) ; where d = distance
Let constant fee per vertical meter = p
F(d) = $100 + 3000 * p
$400 = $100 + 3000p
$400 - $100 = 3000p
$300 = 3000p
p = 300/3000
p = $0.10
Hence, the fee for a trip:
F(d) = $100 + $0.1d

y=100+0.1x
