The path traveled by a bottlenose dolphin as it jumps out of water is modeled by the equation y = −0.4x2 + 3x, where y is the he

Tamiku [17]

Answer:

5 feet

Step-by-step explanation:

The path traveled by a bottlenose dolphin as it jumps out of water is modeled by the equation,

$y=-0.4x^2+3x$

where y is the height above water and x is the horizontal distance in feet.

If a beam of light is shone upward at an angle modeled by the equation

$x+y=10$

A beam of light hit the dolphin.

So, line must be intersect path of dolphin.

Using substation method,

Substitute y=10-x into dolphin equation.

$10-x=-0.4x^2+3x$

$-0.4x^2+4x-10=0$

$x=\dfrac{-4\pm\sqrt{4^2-4(-10)(-0.4)}}{2(-0.4)}$

$x=5\text{ feet }$

$y=5\text{ feet }$

Hence, The beam hit dolphin at 5 feet.

Choose the abbreviation of the postulate or theorem that supports the conclusion that WAS NOT. Given: WS = NT, AS = OT, S = T. S

julsineya [31]

Answer:

The abbreviation of the postulate which can be used to support the conclusion is SAS ( Side Angle Side )

Step-by-step explanation:

Given : WS = NT, AS = OT, S = T

Now, two sides are given to be equal and one angle

So, the similarity postulate which can be used to support the conclusion can be SAS ( Side Angle Side ). But for this postulate to be used, The angle must lie between the two equal sides.

So, the abbreviation of the postulate which can be used to support the conclusion is SAS ( Side Angle Side )
