Answer:

Disadvantages of mathematicsl models are given.

Step-by-step explanation:

Disadvances of mathematicsl models are the model is a limited or bounded cases which taken from huge number of situations by ignoring many unknown facts of the real problem and does not include all important parameters or trivial parameters for accuricy of the result of system dynamics which gives a better result of the problem. The model may also only work in certain major state variables and parameters which may effect largly on the whole system.

Write the quadratic equation in standard form:<br> 7x + 8 + 2x2<br> 2x + 1 + x2

JulsSmile [24]

Answer:

$3x^2 + 9x +9$

Step-by-step explanation:

Given

$(7x + 8 + 2x^2) + (2x + 1 + x^2)$

Required

The result in standard form

We have:

$(7x + 8 + 2x^2) + (2x + 1 + x^2)$

Remove brackets

$7x + 8 + 2x^2 + 2x + 1 + x^2$

Collect like terms

$7x+ 2x + 8 + 1 + 2x^2+ x^2$

$9x + 9+ 3x^2$

The standard form of a quadratic equation is:

$ax^2 + bx + c$

So, we have:

$9x + 9+ 3x^2$

$3x^2 + 9x +9$

WHO CAN solve it Please !

Mariulka [41]

Answer:

a) True

<em> </em> $\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0$ <em></em>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the definite integration</em>

<em> </em> $\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha$ <em></em>

<em>we know that the trigonometric formula</em>

<em> sin²∝+cos²∝ = 1</em>

<em> cos²∝ = 1-sin²∝</em>

<u><em>step(ii):-</em></u>

<em>Now the integration</em>

<em> </em> $\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha = \int\limits^\pi _0 {(\sqrt{cos^{2} \alpha } } \, )d\alpha$ <em></em>

<em> = </em> $\int\limits^\pi _0 {cos\alpha } \, dx$ <em></em>

<em>Now, Integrating </em>

<em> </em> $= ( sin\alpha )_{0} ^{\pi }$ <em></em>

<em> = sin π - sin 0</em>

<em> = 0-0</em>

<em> = 0</em>

<u><em>Final answer:-</em></u>

<em> </em> $\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0$ <em></em>

<em></em>

A survey of teens suggested that 33% can name at least one professional baseball player, and 90% of those teens can also name at

loris [4]

Answer:

$d.\ 0.33 + 0.64 – (0.90)(0.33) = 0.673$

Step-by-step explanation:

Given

$P(Baseball) = 33\%$

$P(Baseball\ n\ Football) = 90\%$

$P(Football) = 64\%$

Required

$P(Baseball\ or\ Football)$

This is calculated as:

$P(Baseball\ or\ Football) =P(Baseball) + P(Football) -P(Baseball\ n\ Football)$

$P(Baseball\ or\ Football) = 0.33 + 0.64 - (0.90)(0.33)$

$P(Baseball\ or\ Football) = 0.33 + 0.64 - 0.297$

$P(Baseball\ or\ Football) = 0.673$
