Furkat [3]

Answer:

t = 5.25 seconds

Step-by-step explanation:

Given that,

A projectile with an initial velocity of 48 feet per second is launched from a building 190 feet tall. The path of the projectile is modeled using the equation:

h(t)=-16t^2+48t+190

It is assumed to find the time when the projectile will hit the ground. When the projectile hit the ground, its height is equal to 0 such that,

-16t^2+48t+190=0

It forms a quadratic equation such that,

t=\dfrac{-b+\sqrt{b^{2}-4ac } }{2a},\dfrac{-b-\sqrt{b^{2}-4ac } }{2a}\\\\t=\dfrac{-48+\sqrt{(48)^{2}-4\times (-16)(190) } }{2\times (-16)},\dfrac{-48-\sqrt{(48)^{2}-4\times (-16)(190) } }{2\times (-16)}\\\\t=-2.25, 5.25

So, the projectile will hit the ground at t = 5.25 seconds.

Find the length of x
zaharov [31]

Answer:

The answer is 2

Step-by-step explanation:

The hypotenuses of the triangles are different. One is 4 and the other is 5.

Lets use ratios to find the relationship of the hypotenuse and the base.

2.5:5

Turn this into a fraction

2.5/5

Now divide

2.5/5 = 0.5

The base of the triangle is half the length of the hypotenuse.

So 4 is x’s hypotenuse so:

4 x 0.5 = 2

X = 2
