Explicación paso a paso:
El tiempo necesario para completar la trayectoria se conoce como tiempo de vuelo.
Tiempo de vuelo = dónde;
U es la velocidad inicial del cuerpo = 47,5 m / s
es el ángulo de lanzamiento = 39,4 °
g es la aceleración debida a la gravedad = 9,81 m / s²
Sustituyendo los parámetros dados en la fórmula anterior, tendremos;
[tex]T = \dfrac{2(47.5)sin39.4^0}{9.81} \\\\T = \dfrac{95sin39.4^0}{9.81} \\\\T = \dfrac{95*0.6347}{9.81} \\\\T = \dfrac{60.2994}{9.81} \\\\T =6.1467 secs[/tex]
El tiempo necesario para completar la trayectoria es de 6.1467 segundos.

|-2y+5|=2|4y-1|
I need help fast please, thanks
Answer:
|-2y+5|=2|4y-1|
-2y+5=8y-2
-2y-8y=-2-5
-10y=-7
y=7/10
Step-by-step explanation:
4x+12y+4z=-16 12x-12y+8z=8 4x+12y-4z=0
Which equation is in standard form?
A. -3(x + y) = 10
B. y = 4x + 2
C. 5x –y = 15
D. 0.5x + 6y = 1.9
Randy is four times as old as Kenneth and Randy is 36 years older than Kenneth
i) How old is Kenneth?
ii) How old is Randy?
Answer:
Kenneth: 12 years old
Randy: 48 years old
Step-by-step explanation:
For this problem, we can use system of equations to solve. Let's use r for Randy and k for Kenneth.
Equation 1
r=4k
This equation comes from the first part, where Randy is four times as old as Kenneth.
Equation 2
r=36+k
This equation comes from the second part, where Randy is 36 years older than Kenneth.
Since we have r=, we can use substitution method.
4k=36+k [subtract both sides by k]
3k=36 [divide both sides by 3]
k=12
Now that we have found k, we can plug that into any equation to find r.
r=4(12) [multiply]
r=48
Now, we know that Randy is 48 years old and Kenneth is 12 years old.

-one 90 degree angle
-the two angles that are not the right angle (90 degree angle) will always be acute angles
-the hypotenuse can easily be found by using the Pythagorean Theorem (a squared plus b squared equals c squared
-it has three sides
-it has three angles

Joes mother gave him 1/3 of the money in her purse. His father gave him 5.00. If they gave joe a total of 12.00, How much money did his mother have in her purse. Joes mother had $ money in her purse (Enter a number only and make sure to include the decimal and 2 numerical decimal places.)
Answer:
$21Step-by-step explanation:
let the money in her purse be $x
1/3 of the money is 1/3x
Since his father gave him $5 and the total amount became $12
the expression for the total amount would be
12= 1/3x+5
We can now solve for x
12-5= 1/3x
1/3x= 7
cross multiply we have
x= 7*3
x= $21
Therefore the money in joes mother's purse is $21

FIRST ONE TO ANSWER GETS BRAIN LISTED!
Answer:
8
Step-by-step explanation:
Do |7 - 9| first, and you get -2, however since it is absolute value, you use the positive version, making it two. Now you have 5|2|-2. Multiply 5*2=10. Then subtract 2.
Solve.
1) (-85) ÷ 20 =
2] 100 ÷ 60 =
[tex] - 85 \div 20 = - 4 \frac{1}{4} = - 4.25[/tex]
[tex]100 \div 60 = \frac{5}{3} = 1 \frac{2}{3} [/tex]

Write the equation g(x) of the transformation of the parent graph f(x) = |x| reflected over the x axis.
Answer:
g(x) = -|x|
Step-by-step explanation:
f(x) = |x|
y = −f(x) Reflects it about x-axis
g(x) = -|x|
We start off with: f(x) = |x|
Reflection across x-axis
y = -f(x)
After: g(x) = -|x|
Best of Luck!

-3xy = what when x=11 and y =-4?
Answer:
132
Step-by-step explanation:
-3xy
x=11 and y = -4
= -3 *11*-4
-33 * -4
132
If x = 11 and y = -4
-3xy = -3 × 11 × -4
= -3 × -44
= 132.... Hope this will help....

Solve 3x - x + 2 = 12.
O 1) – 5
O 2) 4
0 3 7
4) 5
Answer:
4) 5
Step-by-step explanation:
3x-x+2=12
First, you combine similar terms, so 3x-x which is 2x.
Second, you subtract 2 on both sides which is going to give you 2x=10.
Finally, you divide by 2 on both sides, so the final answer is going to be x=5.
