The horizontal distance to the control tower is approximately 18506.83m

Data;

distance from the ground = 3900m
angle of elevation = 11.4 degrees
horizontal distance = ?

<h3>Trigonometric Ratio</h3>

To solve this problem, we need to use trigonometric ratio SOHCAHTOA.

In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.

$tan\theta = \frac{opposite}{adjacent} \\tan11.4 = \frac{3900}{x}\\x = \frac{3900}{tan11.4}\\ x = 18506.83m$

The horizontal distance to the control tower is approximately 18506.83m

If you were given the choice of between more initial zombies, but a slower growth rate or fewer initial zombies, but a greater g

Digiron [165]

I would choose to have a higher initial rate of zombies with a slower growth rate because (although it would be difficult in the beginning) i would have more time to prepare for the zombies.

An arrow is shot vertically upward from a platform 16ft high at a rate of 190ft/sec. When will the arrow hit the ground?

natta225 [31]

Answer:

time required for arrow to reach ground is 10.8 sec

when t = 10.8 seconds to the nearest tenth

Step-by-step explanation:

Given values are

Velocity = 190 ft/sec height = 16 ft

Given formula is

h=−16t²+vt+h0

adding the values, we get

h(t)= -16t²+190t+16

so we have to find when the hit he ground, so at ground the height will be 0

0= -16t²+190t+16

-16t²² + 190t + 16= 0

using the quadratic formula

x = (-b +(b2 - 4ac)1/2)/2a

values

a = -16, b = 190, c = 16

x= -190 + ((-190)²- 4 (-16)(16) ½ / 2(-16)

x= -190 + ((-190) ²+1024) ½ / 2(-16)

x= -190+ (-190²+ 32²) ½ /-32

taking under root

x= -190 + ( -190+32)/ -32

x= 190 + (-158)/-32

we have 2 options,

x= 190 + (-158)/-32 x= 190 - (-158)/-32

x= 190 -158)/-32 x= 190 +158)/-32

x= -1 x= 10.875

or t = 10.875

so the negative root has no practical significance

and we have t = 10.8 seconds to the nearest tenth
