(x,y)

Quartile 1/original coordinates (x,y)
Quartile 2 (-x,y)
Quartile 3 (-x,-y)
Quartile 4 (x,-y)

use this to move a shape on the graph

the degree of rotation of a shape on a graph depends on where the shape starts and ends

A flight from houston to chicago is approximately 940 miles. A plane making this flight is traveling at an average rate of 485 m
fomenos

Answer:

D(t) = 485t + 940

Step-by-step explanation:

D(t) = ?

We are told that the flight itself is 940 miles. This is a constant value, it will not change.

D(t) = ? + 940

Following this, we are also told the plane travels at 485 miles per hour. MPH usually indicates multiplication. 485 miles <em>per</em> each of hour (time here is represented by the variable t). 485t

D(t) = 485t + 940

a garden pond is in the shape of a rectangle that measures 5 m by 3 m. a stone path is built all around the pond. this path is t
Inessa [10]

Answer:

<u>1.16 m (approximately)</u>

Step-by-step explanation:

Let x be the width of the path.

Total area  = (5+2x)(3+2x) = 39

Expand and simplify

4x²+ 16x+15-39 = 0

4x² + 16x - 24 = 0

Simplify

x² + 4x -6 = 0

Rational factoring does not work, so use quadratic formula

x = +/- sqrt(10) -2

= 1.16 or -5.16 (reject)

= <u>1.16 m (approximately)</u>

The mean of 100 observation is found to be 40. If at the time of compution two items were wrongly taken as 30 and 27 instead of
Colt1911 [192]

Answer:

40.18

Step-by-step explanation:

According to this question, the mean of 100 observation is found to be 40. This means that the number of values in the set of data is 100. However, at the time of computation two items were wrongly taken as 30 and 27 instead of 3 and 72.

The mean is derived by dividing the sum of values in the data (Σx) by the number of observations (n) i.e.

Mean = Σx/n

For the computation error:

Mean = 40

Let x represent the sun of other 98 values except 30 and 27

n = 100

40 = x + 30 + 27/100

40 = 57 + x/100

Cross multiply

4000 = 57 + x

x = 4000 - 57

x = 3943.

Sum of other 98 values = 3943.

Now, let's find the correct mean with correct values of 3 and 72;

Mean = Σx/n

Mean = 3943 + 3 + 72/100

Mean = 4018/100

Mean = 40.18

Which is bigger? 1.27 or 1 1/3?
uranmaximum [27]
11/3 is bigger 1.27 because when you do 11/3 you get 3.66666666666666666667 which is clearly bigger than 1.27 so like I said 11/3 is bigger than 1.27.
