Heathers weekly pay is directly proportional to the number of hours she works at the record store her pay is 174 for 24 hours of

Karolina [17]

Answer:

Heather pay will be <u>290</u> for 40 hours of work.

Step-by-step explanation:

Given:

Amount he gets paid weekly =174

Number of hours of work =24

we need to find the amount of pay for 40 hours of work.

Also Given:

weekly pay is directly proportional to the number of hours.

Framing in equation form we get;

Amount Of Pay ∝ Number of hours of work

Hence Amount of Pay = k × Numbers of hours of work.

where k is constant.

Substituting the values we will find the value of k

$174 = k \times 24\\\\k = \frac{174}{24} = 7.25$

Now using this we will find the amount of pay when hours of work is 40.

Amount Of Pay = $7.25\times 40 = 290$

Hence Heather pay will be <u>290</u> for 40 hours of work.

Lesson: 1.08Given this function: f(x) = 4 cos(TTX) + 1Find the following and be sure to show work for period, maximum, and minim

Ber [7]

The given function is

$f(x)=4\cos \text{(}\pi x)+1$

The general form of the cosine function is

$y=a\cos (bx+c)+d$

a is the amplitude

2pi/b is the period

c is the phase shift

d is the vertical shift

By comparing the two functions

a = 4

b = pi

c = 0

d = 1

Then its period is

$\begin{gathered} \text{Period}=\frac{2\pi}{\pi} \\ \text{Period}=2 \end{gathered}$

The equation of the midline is

$y_{ml}=\frac{y_{\max }+y_{\min }}{2}$

Since the maximum is at the greatest value of cos, which is 1, then

$\begin{gathered} y_{\max }=4(1)+1 \\ y_{\max }=5 \end{gathered}$

Since the minimum is at the smallest value of cos, which is -1, then

$\begin{gathered} y_{\min }=4(-1)+1 \\ y_{\min }=-4+1 \\ y_{\min }=-3 \end{gathered}$

Then substitute them in the equation of the midline

$\begin{gathered} y_{ml}=\frac{5+(-3)}{2} \\ y_{ml}=\frac{2}{2} \\ y_{ml}=1 \end{gathered}$

The answers are:

Period = 2

Equation of the midline is y = 1

Maximum = 5

Minimum = -3

Alyssa started hiking at an elevation of 1500ft. After 2 hours, she was at 1200ft. Which integer desceibes her change in elevati

SpyIntel [72]

Answer:

-300.

Step-by-step explanation:

First, you'd have to subtract 1500 from 1200. This gives you 300, but since she is descending rather than ascending, the number is negative rather than positive.

Please help. Could you explan your answer also? thanks

Answer: Choice B) -4

The lower quartile, also known as Q1 or the first quartile, is the left edge of the box. In this case, that is at -4. We can drop a vertical line from the left edge of the box until we hit -4 on the number line.

Side Note: 25% of the data values are below Q1, while 75% of the data values are above Q1
