5. A ball is thrown straight up leaving the player's hands at at 7.5 m/s. If air resistance is ignored, how high can the ball tr
aleksley [76]

The maximum height reached is 2.87 meters

<h3>What is maximum height?</h3>

The maximum height of an object is the highest vertical position along the trajectory of the object.

The given parameters are:

  • u = 7.5ms^{-1} --- the initial velocity
  • v = 0ms^{-1} --- the final velocity
  • a =-g --- the acceleration

To calculate the height (s) of the ball, we make use of the following equation of motion:

v^2 = u^2 + 2as

Substitute known values

0^2 = 7.5^2 - 2gs

0 = 56.25 - 2gs

Collect like terms

2gs = 56.25

Substitute 9.8 for g

2 \times 9.8 s = 56.25

19.6 s = 56.25

Divide both sides by 19.6

s = 2.87

Hence, the maximum height reached is 2.87 meters

Need help with solving right triangles again, can you guys solve for x too​
Lisa [10]

Answer:

Step-by-step explanation:

sin\theta =\frac{5}{13}\\ \\ \theta =sin^{-1}\frac{5}{13}\\ \\ \theta =22.62^o\\ \\ \\ a=90-22.62\\ \\ a=67.38^o\\ \\ \\ 13^2=5^2+x^2\\ \\ x^2=169-25\\ \\ x^2=144\\ \\ x=\sqrt{144}\\ \\ x=12

Graph the line with slope -1 passing through the point (-1,-4)
Lyrx [107]

Answer: look at pic

Step-by-step explanation:

y=mx+b

m:slope

b:y-intercept

m=-1 (slope) given in the question

y=-1x+b

Plug in the given point (-1,-4) then solve for b

-4=-1(-1)+b

b=-5

y=-x-5

then using the x-intercept and y-intercept you could graph the line

y-intercept = b = -5 (0,-5)

x-intercept (plug in y=0)

0=-x-5

x=-5 (-5,0)

Usando proporciones, en conjunto con multiplicación cruzada, encontra-se que el valor de p es de 6.

<h3>¿Qué es una proporción?</h3>

Una proporción es una fracción de la cantidad total, e puede ser encontrada aplicando una regla de três.

En este problema, relación es dada por:

\frac{p}{p+2} = \frac{6}{8}

Aplicando multiplicación cruzada:

8p = 6(p + 2)

8p = 6p + 12

2p = 12

p = 12/2

p = 6.
