Answer:

$\sin(x _{1} ) = \frac{1}{2} \\ \sin(x _{1} ) = \sin(30 ) \\ x_{1} = 30 \\ \cos(x _{1}) = \cos(30 ) \\ \cos(x _{1}) = \frac{ \sqrt{3} }{2}$

HELP ASAP! PLEASE<br> Solve 1.1(3.4x-2.3)^2=15.5 and write it in ax^2+bx+c=0 form.

lyudmila [28]

Answer:

In the normal ax² + bx + c format, this equation is expressed as:

12.716x² - 17.204x + 9.81 = 0

If we solve for x, it is approximately equal to both 178 and -0.43

Step-by-step explanation:

Let's reformat to ax² + bx + c = 0:

$1.1(3.4x - 2.3)^2 = 15.5\\1.1(11.56x^2 - 15.64x + 5.29) = 15.5\\12.716x^2 - 17.204x + 5.819 = 15.5\\12.716x^2 - 17.204x + 9.81 = 0\\$

And now let's find the value of x

$1.1(3.4x - 2.3)^2 = 15.5\\(3.4x - 2.3)^2 = 15.5 / 1.1\\(3.4x - 2.3)^2 = 14.09\\3.4x - 2.3 = \sqrt{14.09}\\3.4x = 2.3 \pm \sqrt{14.09}\\x = \frac{2.3 \pm 3.75}{3.4}\\x = (1.78, -0.43)$

Antonio uses a function to determine the height of a football from the time is kicked to the time it lands on the ground. Is the

Temka [501]

Answer:

Non-linear

Step-by-step explanation:

Here, we want to determine the function type that would model the height of a football from the time it was kicked to the time it lands on the ground

The way to go about this is to notice the kind of shape or trajectory the kicked football will take.

The shape it will take is non-linear. The shape it will take would be a parabolic curve. These parabolic curve models a quadratic equation and not a linear function. Hence we can conclude that based on the kind of path in which the ball traces, we can conclude that the function that results from its trajectory would not be a linear kind of equation or representation.
