is this quadratic equation

This is solution for the third image

x^2 + 2x - 24

x^2 + 6x - 4x - 24

x (x + 6) - 4 (x + 6)

(x + 6) (x - 4)

x + 6 = 0    ,    x - 4 = 0

Therefore, x = - 6  ,  x = 4

This solution is for the first image

2x^2 + 14x + 24

2x^2 + 8x + 6x + 24

2x (x + 4) + 6 (x + 4)

(x + 4) (2x + 6)

x + 4 = 0    ,    2x + 6 = 0

Therefore, x = - 4   ,   2x = 6

                                   x = 6/2 = 3

Find the direction angle of 3i+1j.<br><br> Please help me. Thank you
Alekssandra [29.7K]

Answer:

Correct answer:  ∝ = 18.43°

Step-by-step explanation:

Given coordinates represent one vector in x-y plane, let be v.

v = 3i +1j = xi + yj => x = 3 and y = 1

The angle that this vector builds with the positive direction to the x axis will be found using the tangent.

∝ = tan⁻¹ y/x = tan⁻¹ 1/3 = tan⁻¹ 0.333 = 18.43°

∝ = 18.43°

A swimming pool has a length of 25 ft, a width of 15 fr, and a depth of 4 ft. What is the volume of the water in this pool when
timofeeve [1]

Answer:

1312.5 cubic feet

Step-by-step explanation:

Let the swimming pool be a rectangular prism

The volume of a rectangular prism is:

Volume = length * width * depth

Length = 25 (given)

Width = 15 (given)

The depth is 4ft, but they want the volume when water is 6 inches FROM THE TOP, that is, out of 4 feet, 6 inches (1/2 feet) IS NOT FILLED. So the depth of water is

4 - 1/2 = 3.5 feet

So, we can say

Depth = 3.5 (found)

Hence, the volume would be:

Volume = 25 * 15 * 3.5 = 1312.5 cubic feet
