Answer:

12 minutes

Step-by-step explanation:

The radius is half the diameter, so 18*2 = 36 inches

The diameter is 36 inches.

Divide the diameter by the rate, 36/3 = 12 minutes

Your answer is 12 minutes

The equation of a line is 4x−3y=−244x−3y=−24. What is the x-intercept of the line? Enter your answer below.

GREYUIT [131]

The x-intercept is the point where the line intersects the x-axis which means that it is the value of x when y in the equation is set to be equal to zero. In the equation of the line given, setting the y value to zero will result to an x value of -1/2. Therefore, the x-intercept would be -1/2.

Identify the sequence as arithmetic, geometric, both, or neither. 50, –50, 50, –50, . . . both arithmetic geometric neither desc

stellarik [79]

Answer:

<em>The sequence is geometric.</em>

Step-by-step explanation:

In Arithmetic sequence, there is a common difference between any two consecutive terms but in Geometric sequence, there is a common ratio between any two consecutive terms.

Given sequence is: 50, -50, 50, -50,.................

Lets assume, the terms as $a_{1}, a_{2}, a_{3}, a_{4},...........$

<em><u>Checking for common difference:</u></em>

$a_{2}-a_{1}= (-50)-(50)= -100\\ \\ a_{3}-a_{2}=(50)-(-50)=100\\ \\ a_{4}-a_{3}=(-50)-(50)=-100$

As there is no common difference, so it's not an arithmetic sequence.

<u><em>Checking for common ratio</em></u>

$\frac{a_{2}}{a_{1}}=\frac{-50}{50}=-1\\ \\ \frac{a_{3}}{a_{2}}=\frac{50}{-50}=-1\\ \\ \frac{a_{4}}{a_{3}}=\frac{-50}{50}=-1$

As there is a common ratio, so it's a geometric sequence.

Please help ASAP!!!!! will mark you brainliest thank you!

Answer:

Step-by-step explanation:

1. The coefficient of 2 $x^{2}$ is 2. Therefore, the answer is 2 for a. 1 is the coefficient of -x after we add it to the left side. Therefore, b is 1. C is 5, as it is the only whole number.

This means that the answer is a = 2, b =1, c =5.

2. You can simply cancel out both 3s by dividing, which leaves us with 1±9 $\sqrt{5}$ .

3. The answer is c. Unfortunately, I can't explain that, it's just a well known formula.

I hope this helped!
