Olegator [25]3 years ago

Answer:

r = 2.8 in ( to 1 dec. place )

Step-by-step explanation:

substitute the given values into the formula

25 = 3.14r² ( divide both sides by 3.14 )

r² = \frac{25}{3.14} ( take the square root of both sides )

r = \sqrt{\frac{25}{3.14} } ≈ 2.8 in

Select the two statements that are true about the equation y+6=−10(x−3).
qwelly [4]

I have taken that test (although I don't see you're statements)

I believe the statements to choose from are:

A.) The slope of the line is −10.

B.) The slope of the line is 3.

C.) One point on the line is (3, 6).

D.) One point on the line is (3,−6)

<u>The answers are:</u>

A.) The slope of the line is -10

D.) One point on the line is (3,-6)

<u>Explanation: </u>

The given equation of line is (1).  The point slope form of a line is  (2)  Where m is the slope of line and (x₁,y₁) are points.  On comparing (1) and (2) we get The slope of given line is -10 and the line passing through the points (3,-6).

At time t=3, there are 2.5 cubic feet of water in the tub. Write an equation for the locally linear approximation of W at t=3, a
velikii [3]

Answer:

W=0.8333*t

2.917 ft³

Step-by-step explanation:

At time t=3, there is 2.5 ft³ of water in the tub

Finding the relation will be;

3=2.5

1=?

Rate=0.8333 ft³/min

W=0.8333 ft³ / min

W=0.8333*t

At t=3.5 will be;

1 min = 0.8333

3.5 min =?

Apply cross-production

3.5*0.8333 =2.917 ft³

What is the median of the following data set -1000, -999, 1998, ..., -1, 0, 1, ..., 998, 999, 1000
qwelly [4]

<u>Answer:</u>

The correct answer option is C. 0.

<u>Step-by-step explanation:</u>

We are given the following data set and we are to find its median value:

- 1 0 0 0 , - 9 9 9 , 1 9 9 8 , ... , -1 , 0 , 1 , ... , 9 9 8 , 9 9 9 , 1 0 0 0

Median is the middle value of a data set which divides it into to halves.

The data set we have starts from -1000 and goes till 1000 which means there are total 2001 elements in it.

Therefore, 0 will the middle value which is the median for this data set.
