If the diagonal of a square is 11.3 what is the perimeter

Mathematics

zimovet [89]3 years ago

Answer:

Step-by-step explanation:

if the diagonal of a square is 11.3 what is the perimeter

from the diagonal we find the area, which can also be found by multiplying diagonal by diagonal divided by two, then we make the square root of the area and find the side, we multiply by four and we have the perimeter

(11.3 * 11.3) : 2 = 63.8 u² (Area)

√63.8 = 7.9 (side)

7.9 * 4 = 31.6u (perimeter)

7. Use the discriminant to determine how many real number solutions exist for the quadratic equation –4j2 + 3j – 28 = 0.
GrogVix [38]
\bf \begin{array}{llccll}&#10;y=&{{ -4}}j^2&{{ +3}}j&{{ -28}}\\&#10;&~\uparrow &\uparrow &\uparrow \\&#10;&~a&b&c&#10;\end{array}&#10;\\\\\\&#10;discriminant\implies b^2-4ac=&#10;\begin{cases}&#10;0&\textit{one solution}\\&#10;positive&\textit{two solutions}\\&#10;negative&\textit{no solution}&#10;\end{cases}

so.. check what value the discriminant is then.

dusya [7]

Answer:

1. 2 / 5 - Fractional form, 0.4 - Decimal Form

2. 5 / 8 - Fractional form, 0.625 - Decimal Form

3. 6 / 7 - Fractional form, 0.8571 - Decimal Form

4. \sqrt{a / b}

5. \sqrt{a * b}

Step-by-step explanation:

1. \sqrt{4 / 25}

Steps:

1. Divide  - 4 / 25

2. Then take the square root of what you got - \sqrt{0.16} = 0.4

2. \sqrt{25 / 64}

Steps:

1. Divide - 25 / 64

2. Then take the square root of what you got - 5 / 8

3. \sqrt{36 / 49}

Steps:

1. Take the square root of the top number - 6

2. Tage the square root of the bottom number - 7

3. Answer is 6/7.

4. \sqrt{a} / \sqrt{b} = \sqrt{a / b}

5. \sqrt{a}  * \sqrt{b} = \sqrt{a * b}

<em><u>Formula:</u></em>

\sqrt{a} / \sqrt{b} = \sqrt{a / b}

\sqrt{a} * \sqrt{b} = \sqrt{a * b}
