We can say that the 8 foot base is the adjacent side.
We can say that the 5 foot altitude is the opposite side.
the tangent of the base angle = 5/8 = .625
Therefore the angle equals
arc tangent (.625) = 32.005 degrees

Factor completely 2x5 + 10x4 − 22x3.
Luba_88 [7]

Given equation is :

2x^{5}+10x^{4}-22x^{3}=0

Taking out 2x^{3} common we get,

x^{2}+5x-11=0

Now solving this we get,

As 11 is not factor-able, we will solve it using the formula,

x=\frac{-b+\sqrt{b^{2}-4ac}}{2a}

a=1 b=5 and c=-11

we get,

x=\frac{-5+\sqrt{69} }{2} and x=\frac{-5-\sqrt{69} }{2}

An arrow is shot vertically upward at a rate of 240 feet per second from ground level. Use the projectile formula to determine w
Juli2301 [7.4K]

Answer:

After 14.92 seconds, the arrow hits the ground.

Step-by-step explanation:

Given:

Initial velocity of the arrow is, u=240\ ft/s or 73.152\ m/s

The arrow goes up and come back to the same starting position. So, initial position is same as that of final position.

Therefore, displacement of the arrow is 0 m.

The displacement of the arrow is given as:

s=ut-\frac{1}{2}gt^{2}   (equation 1)

Plug all value in equation 1 and solve for t

0=73.152\timests t-\frac{1}{2} \times9.8 \times t^{2}

0=73.152\timests t-4.9 \times t^{2}

0=t(73.152-4.9 \times t)

73.152-4.9\times t=0     where t\neq 0

4.9\times t=73.152

t=\frac{73.152}{4.9}= 14.92\ s

∴ After 14.92 seconds, the arrow hits the ground.
