Write the equation for a line that passes through (4,-1) and has a slope of 5
Answers
Answer:
y = 5x - 21
Step-by-step explanation:
Since we already know the slope, all we need to do is plug the values of x and y into the equation.
y = 5x + b
-1 = 5(4) + b
-1 = 20 + b
-21 = b
The equation is y = 5x - 21.
Se ha construido un cuadrado sobre cada lado del triángulo rectángulo, Pitágoras dice que el cuadrado de área 25 cm2, es igual a sumar las áreas de los otros dos cuadrados, es decir, 16 cm2 y 9 cm2. Escribir la expresión algebraica que mejor represente la relación entre las áreas en la figura.
Answers
Answer:
Tenemos la siguiente expresión algebraica:
[tex]c^{2} = a^{2}+b^{2}[/tex] (1)
Donde:
[tex]c[/tex] - Hipotenusa, en centímetros.
[tex]a, b[/tex] - Catetos, en centímetros.
Step-by-step explanation:
Este ejercicio ofrece un recurso mnemotécnico para la comprensión y aplicación del Teorema de Pitágoras, el cual establece que el cuadrado de la hipotenusa es igual a la suma de los catetos elevados al cuadrado, siendo cada componente equivalente al área de un cuadrado hipotético, entonces, la expresión algebraica que representa esa relación entre las áreas es:
[tex]25\,cm^{2} = 16\,cm^{2} + 9\,cm^{2}[/tex]
[tex](5\,cm)^{2} = (4\,cm)^{2}+(3\,cm)^{2}[/tex]
Por analogía, tenemos la siguiente expresión algebraica:
[tex]c^{2} = a^{2}+b^{2}[/tex] (1)
Donde:
[tex]c[/tex] - Hipotenusa, en centímetros.
[tex]a, b[/tex] - Catetos, en centímetros.

A soccer ball is kicked from the ground with an initial upward velocity of 90 feet per second. The equation h=-16t^2+90t gives the height h of the ball after t seconds.
a. Find the maximum height of the ball.
b. How many seconds will it take for the ball to reach the ground?
Answers
The ball reaches a height of 126.58 ft after 2.8125 seconds
Step-by-step explanation:
The maximum height of a parabola can always be found by looking for the vertex. You can find the x value (or in this case the t value) of a vertex by using -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(90)/2(-16)
-90/-32
2.8125 seconds
Now to find the height, we input that value in for t
h = -16t^2 + 90t
h = -16(2.8125)^2 + 90(2.8125)
126.58 feet

Find:
Value of 10z
Computation:
We know that in given equation 10z
10 is constant(fixed value) and z is variable(changeable value)
where value of variable z is given 0.8
So,
By putting value of variable z in given equation
⇒ 10z
⇒ 10(0.8)
by multiplying variable and constant
Value of 10z = 8

Answers
Answer:
f(0) = 0 and f(−2) = f(2)
Step-by-step explanation:
Given: the function f defined by f(x) = 3x²
f(0) = 3(0)²
f(0) = 0
f(-2) = 3(-2)²
f(-2) = 3(4)
f(-2) = 12
f(2) = 3(2)²
f(2) = 3(4)
f(2) = 12
Hence f(-2) = f(2)
Therefore the correct options are f(0) = 0 and f(−2) = f(2)

Answer:
12, 6, 4, 3, 12/7
Step-by-step explanation:
so for each column, you would substitute the number for a in the equation. for example, substituting 2 for a will make the equation 2/2 + b = 12. we now need to isolate b. 2/2(2/2 + b) = 12(2/2) makes the new equation b = 24/2, or b = 12.
Answer:
11,10,9,8,5
Step-by-step explanation:
look at the table.
they are giving you what a equals.
for example: in the table, it says a is 2. SO you put that into the equation you are given.
[tex]\frac{a}{2}[/tex] + b = 12 substitute "a" which we know is 2 into the equation
[tex]\frac{2}{2}[/tex] + b = 12 NOW you solve for b
first, divide 2 by 2 which equals 1
THEN subtract 1 by 12 giving you 11. The equation should look like this
b = 11
11 can then go under 2 on the table.
