In any given week, salesman A earns $65 per sale, so his paycheck amounts to $p_A(s)=65s$ (where $0\le s\le20$ ).

Salesman B earns $40 per sale, with a weekly salary of $300, so in any given week this salesman earns $p_B(s)=45s+300$ .

Salesman C earns a flat rate of $900 per week regardless of the number of sales, so his weekly pay is $p_C(s)=900$ .

On the line you created from part A, mark a point D that is distinct from point C. Then, use the slope formula along with the co

ad-work [718]

The slope of AB and the slope of DC based on the information about the coordinate will be -2 and -2 respectively.

<h3>How to illustrate the information?</h3>

From the information given, we are told to use the slope formula along with the coordinates of points A, B, C, and D to find the slope.

The slope of AB based on the information will be:

= (-1 -3)/(-1 --3)

= -4/2

= 2

The slope of DC will be:

= 2-6/(1 --1)

= -4/2

= -2

Therefore, the slope of AB and the slope of DC based on the information about the coordinate will be -2 and -2 respectively.

Find the angle between the hands of a clock at 5:15 A 60 B 67.5 C 75

Viktor [21]

Answer:

Option B is correct.

67.5 degree

Step-by-step explanation:

To find the angle between the hands of a clock.

Given that:

Hands of a clock at 5 : 15.

We know that:

A clock is a circle and it always contains 360 degree.

Since, there are 60 minutes on a clock.

$\frac{360^{\circ}}{60 minutes} = 6^{\circ} per minutes$

so, each minute is 6 degree.

The minutes hand on the clock will point at 15 minute,

then, its position on the clock is:

$(15) \cdot 6^{\circ} = 90^{\circ}$

Also, there are 12 hours on the clock

⇒Each hour is 30 degree.

Now, can calculate where the hour hand at 5:00 clock.

⇒ $5 \cdot 30 =150^{\circ}$

Since, the hours hand is between 5 and 6 and we are looking for 5:15 then :

15 minutes is equal to $\frac{1}{4}$ of an hour

⇒ $150+\frac{1}{4}(30) = 150+7.5 = 157.5^{\circ}$

Then the angle between two hands of clock:

⇒ $\theta = 150.75 -90 = 67.5^{\circ}$

Therefore, the angle between the hands of a clock at 5: 15 is: 67.5 degree.

Please help me with this.

The speed intervals such that the mileage of the vehicle described is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h]

<h3>How to determine the range of speed associate to desired gas mileages</h3>

In this question we have a quadratic function of the gas mileage (g), in miles per gallon, in terms of the vehicle speed (v), in miles per hour. Based on the information given in the statement we must solve for v the following quadratic function:

g = 10 + 0.7 · v - 0.01 · v² (1)

An effective approach consists in using a graphing tool, in which a horizontal line (g = 20) is applied on the maximum desired mileage such that we can determine the speed intervals. The speed intervals such that the mileage of the vehicle is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h].
