Positive integers greater than -6 but less than +21

Nina [5.8K]

Step-by-step explanation:

Inequality to describe problem:

$- 6 < x < 21$

x represents the unknown integer(s).

Integers are positive or negative numbers that don't have a fraction, or a decimal.

Positive integers that work in the inequality:

$- 6 < 1< 21$

$- 6 < 2 < 21$

$- 6 < 3 < 21$

$- 6 < 4 < 21$

$- 6 < 5 < 21$

$- 6 < 6 < 21$

$- 6 < 7 < 21$

$- 6 < 8 < 21$

$- 6 < 9 < 21$

$- 6 < 10< 21$

$- 6 < 11 < 21$

$- 6 < 12 < 21$

$- 6 < 13 < 21$

$- 6 < 14 < 21$

$- 6 < 15 < 21$

$- 6 < 16 < 21$

$- 6 < 17 < 21$

$- 6 < 18 < 21$

$- 6 < 19 < 21$

$- 6 < 20 < 21$

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 work out as positive integers.

Please help!! In radians, what is the period of the function y = .5cos5x

Levart [38]

Answer:

(2pi)/5

Step-by-step explanation:

The cosine function cos(x) has a period of 2*pi.

If we change the argument of the cosine, the new argument will have a period of 2*pi. If the new argument is 5x, we have that the period will be:

5x = 2*pi

x = 2*pi/5

The period of this function will be (2pi)/5, because for every (2pi)/5 change in the value of x, the function will have the same value. The value of 5 multiplying the cosine does not interfere in the period.

Jaden is flying a kite and let’s off 275 feet of string. If the kite is 150 feet above ground and assuming the string is straigh

vivado [14]

Answer:

≈ 33°

Step-by-step explanation:

So, first, you can draw a visual. Refer to the image attached below:

Using this info, you can use trigonometric ratios. Recall that:

tangent = opposite side/adjacent side

sine = opposite side/ hypotenuse

cosine = adjacent side/hypotenuse

You can clearly see that you have an opposite side and a given hypotenuse. This means we'll be using sine.

So:

$sinX = \frac{150}{275}$

However, we're not trying to find sinX, we're trying to find X.

So we would have to use inverse sine, which would then be:

$X = sin-1 (\frac{150}{275} )$

Put this into your calculator, and:

X ≈ 33.05573115...

What is the value of x will make the inequality true. 5x - 10 < 75?

Ipatiy [6.2K]

Answer:

x=16 or any value less than 16.

Step-by-step explanation:

16x5=80 and subtract 10 you get 70. X has to equal a value that makes the whole left side of the equation "smaller" than the irght side, and 16 or any value less than that would accomplsish this.
