The value of x when y= 24 is -26

<h3>How to determine the value of x?</h3>

The given parameters are:

y varies directly with x, and y = 16 when x = -4.

This means that

y = kx

Where k is the constant of variation

So, we have:

16 = -4k

Divide by -4

k = -4

Substitute k = -4 in y = kx

y = -4x

When y = 24, we have:

24 = -4x

Divide by -4

x = -6

Hence, the value of x when y= 24 is -26

Answer:

<h2> Driver B has the fastest race time</h2>

Step-by-step explanation:

From the options presented, driver B has the fastest typical race time because he recorded the smallest time taken to complete an individual race.

Also from the standard deviation given (3.96) for driver B, it shows that the individual time spread from the standard deviation is minimal and that the driver maintained a fairly consistent time of race throughout the racing period.

A cell phone plan charges $15$15 per month for 300300 text messages. The plan charges $0.08$0.08 for each additional text messag

Reika [66]

The company charges 15 dollars per month for first 300 text messages and thereafter 0.08 dollars for any additional text message.

It says that we used additional 60 text messages (after fair usage of first 300 messages in the plan).

Our bill for this month would be sum of charges for 300 messages and charges for additional 60 messages.

Total bill = 15 dollars + 60x0.08 dollars = (15 + 4.80) dollars.

Total bill = 19.80 dollars.

Hence, our bill this month would be 19.80 dollars.

If sin theta = -1/2 and lies in the third quadrant, what is the cos?

never [62]

Sin angle that equals the 1/2 value is the 30 degree on the 1st Quadrant.

The angle of 30 degree on the 3rd Quadrant is equivalent to (formula and circle in the 1st photo) 180 + 30 = 210°.

So theta = 210° (3rd Quadrant) = 30° (1st Quadrant).

$cos \: 30\degree = \sqrt{3} \div 2$

Now just transfer the cos 30° to the 3rd Quadrant and the signal will be negative (as shown in the 2nd photo attached).

$cos \: 210 \degree = - \sqrt{3} \div 2$
