Answer:

length = 22, width = 9

step by step explanation :

perimeter = 62

length = 3×width -5

∴ 2 ( length + width ) = perimeter

2 ( 3w-5 + w ) = 62

3w -5 + w = 62/2 = 31

3w -5 + w = 31

4w = 31 + 5 = 36

4w = 36

w =36/4

w = 9

l= 3w-5 = (3×9)-5 = 27-5= 22

verifying -

2( l + b) = perimeter

2 ( 22 + 9 ) = 2 * 31 = 62

A polynomial P has non-negative integer coefficients. If P(1) = 8 and P(10) = 2312, what is P(2)?

Answer:

Step-by-step explanation:

If coefficients are positive integers, then the polynomial cannot be higher degree than 3. 10^4 = 10,000, so even a coefficient of 1 will give too large a value. P(1) = 8 tells us that the sum of coefficients must be 8, so we cannot have a degree lower than 3.

The sum of digits in 2312 is 8, so it works out that the polynomial is ...

P(x) = 2x^3 +3x^2 +x +2 . . . . matches P(1) = 8 and P(10) = 2312

Then P(2) is ...

P(2) = ((2·2 +3)2 +1)2 +2

P(2) = 32

Use the following cell phone airport data speeds (Mbps) from a particular network. Find the percentile corresponding to the dat

slavikrds [6]

Answer:

The data speed 1.4Mbps is in the 34th percentile.

Step-by-step explanation:

To find the percentile of a value X in a data set, we divide the number of values lesser than X in the data set by the total number of values in the data set, and then multiply by 100.

In this set

There are 17 values lesser than 1.4

There are 50 values in all.

$P = 100*\frac{17}{50} = 34$

The data speed 1.4Mbps is in the 34th percentile.

When you rotate 90 degrees clockwise, (x,y) becomes (y,-x).

Therefore:
G = (3,1)
H = (0, 4)
I = (-2, -3)
