Which statements verify that the solution set to |x + 3| < 5 is –8 < x < 2? Check all that apply. Substituting a value

into the inequality from the solution set, such as –2, will create a true statement. Substituting a value into the inequality from the solution set, such as 1, will create a false statement. Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. Substituting any value into the inequality will create a true statement.

Find the missing side round to the nearest tenth can someone please help me this is my last question
jeka57 [31]

The question is related to trigonometric ratio rule .

In the given diagram, there is a right angle triangle, with adjacent =57, and the unknown side is y. Given angle measurement is 39 .

To find the measurement of y, we will use tan rule which is

tan \Theta = \frac{opposite}{adjacent}

tan 39=\frac{y}{57}

y = 57 tan 39 = 46.2

Camila is putting together gift bags for nurses at a local clinic. Each of the 5 gift bags contains 'x' cookies. Camila adds 3 m
Vladimir [108]

Answer:

A- X= 20÷5-3

B- 20÷5=4; 4-3=1

C- X=1

Step-by-step explanation:

Okay, well we have to work backwards. 20 cookies, and she makes 5 bags. We need to find out what 'x' means. To do that, we take 20 cookies and divide it by 5. 4 cookies. Then we want to take 3 cookies out of each bag to find out how many cookies she first put in. 1 cookie.

Let's check:

bag 1:

o (one cookie)

bag 2:

o (one cookie)

bag 3:

o (one cookie)

bag 4:

o (one cookie)

bag 5:

o (one cookie)

Now we have 15 cookies left. Now let's put 3 in each:

bag 1:

o (one cookie)

v v v ( three cookies)

bag 2:

o (one cookie)

v v v ( three cookies)

bag 3:

o (one cookie)

v v v ( three cookies)

bag 4:

o (one cookie)

v v v ( three cookies)

bag 5:

o (one cookie)

v v v ( three cookies)

Now we have no cookies left, and we put 4 cookies in each. (o representing the first cookie, v representing the next three cookies)

1) State the amplitude, period, phase shift, vertical shift and graph
bogdanovich [222]

Answer:

See answers and explanations below (along with a visual graph)

Step-by-step explanation:

For the function y=acos(b(x+c))+d:

Amplitude: |a|

Period: \frac{2\pi}{|b|}

Phase shift: \frac{-c}{b}

Vertical shift: d

Therefore, for y=2cos(\frac{2}{3}(\theta+\pi))-1:

Amplitude: |a|=|2|=2, which is 2 units above and below the midline (see d)

Period: \frac{2\pi}{|b|}=\frac{2\pi}{|\frac{2}{3}|}=\frac{2\pi}{\frac{2}{3}}=3\pi, so the cycle will repeat every 3π units

Phase shift: \frac{-c}{b}=\frac{-\frac{2\pi}{3} }{\frac{2}{3} }=-\pi, or π units to the left

Vertical shift: d=-1, or 1 unit down
