How to solve the inequality

1 answer:

GaryK [48]3 years ago

4 0

The problem is not shown clearly therefore i am not sure if my answer will be correct, but, this inequality is already solved. all this means is that y is more than or equal to 4.5 (meaning that y can be 4.5, 5, 6, 7, 8 and so own but never a number less than 4.5), the "I I" only mean that y will never be a negative.

Answer:

$\frac{ \cos(80) }{ \sin(10) } + \frac{ \sin(20) }{ \cos(70) } = 2 \\ \frac{ \cos(90 - 10) }{ \sin(10) } + \frac{ \sin(20) }{ \cos(9 0 - 20) } = 2 \\ \frac{ \sin(10) }{ \sin(10) } + \frac{ \sin(20) }{ \sin(20) } = 2 \\ 1 + 1 = 2 \\ 2 = 2 \\ \\ \frac{ \cot(40) }{ \tan(50) } + \frac{ \cos(65) }{ \sin(115) } = 2 \\ \frac{ \cot(90 - 50) }{ \tan(50) } + \frac{ \cos(65) }{ \sin(90 + 65) } = 2 \\ \frac{ \tan(50) }{ \tan(50) } + \frac{ \cos(65) }{ \cos(65) } = 2 \\ 1 + 1 \\ = 2$

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the

worty [1.4K]

Answer:

The maximum height is 1087.06 ft.

Step-by-step explanation:

We need to take the derivative of the equation and set it to 0.

$y' = - 32x + 254 = 0\\32x = 254\\x = 7.9375$

We now can plug x = 7.9375 into the original equation.

$y=-16x^{2} +254x+79\\y=-16(7.9375)^{2}+254(7.9375)+79\\y=1087.06 ft$

Find the slope of a line parallel to y=(2/5)x + (4/5)

Tcecarenko [31]

Answer:

So if a line was parallel it would have same slope. You can search up what slope-intercept form means. But if you have an equation like this:

y = mx+b

The slope will be m. Your question is written in the form. 2/5 = m.

The slope is 2/5

The y-intercept is 4/5
