The height of the higher board above the water surface is 12 feet.

The distance from the high dive to the bottom of the deep end is 24 feet.

<h3>What does division mean?</h3>

Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.

<h3>What is the height of the higher board above the water surface?</h3>

In order to determine the height of the higher board, divide the height of the lower board by 25%.

Height of the higher board = 3 feet / 25%

3 / 0.25 = 12 feet

<h3>what is the distance from the high dive to the bottom of the deep end?</h3>

12 feet + 12 feet = 24  feet

The volume of a rectangular prism can be found by multiplying the base area, B, times the height. If the volume of the prism is
PSYCHO15rus [73]

Answer:

Base (B) = /frac{15x² + 1 + 2}{x}

Step-by-step Explanation:

==>Given:

Dimensions of a rectangular prism are expressed as follow:

Volume (V) = 15x² + x + 2

Height (h) = x²

==>Required:

Expression of the Base area (B)

==>Solution:

Volume (V) = Base (B) × Height (h)

15x² + x + 2 = B × x²

Divide both sides by x²

\frac{15x² + x + 2}{x²} = B[tex]Base (B) = /frac{15x² + 1 + 2}{x}

What error did zacharias make? the –5 should be 5. the 52 should be –52. the 2 in the numerator should be –2. the 2 in the denom
Contact [7]

The error made by zacharias in solving the quadratic equation 0 = -2x² + 5x - 3 using quadratic formula is; the 2 in the numerator should be –2.

<h3>Quadratic equation</h3>

There are four methods of solving quadratic equation. Namely;

  • Factorization method
  • Completing the square method
  • Graphical method
  • Formula method

0 = -2x² + 5x - 3

  • Using quadratic formula

x = -b ± √b² - 4ac / 2a

where,

  • a = -2
  • b = 5
  • c = -3

x = -b ± √b² - 4ac / 2a

x = -5 ± √5² - 4(-2)(-3) / 2(-2)

= -5 ± √25 - (24) / -2

= -5 ± √1 / -2

= -5/2 ± 1/2

= -5/2 - 1/2 or x = -5/2 + 1/2

= -5-1 / 2 or -5+1/ 2

x = -6/2 or -4/2

x = -3 or -2

Therefore, the solution to the quadratic equation is x = -3 or -2
