Answer:

2) y = 0.95x + 4

3) slope: height increases by 0.95 units as x increases by 1 unit

intercept: initial height

Step-by-step explanation:

Using (20,23) and (40,42)

Slope: (42 - 23)/(40 - 20)

0.95

y = 0.95x+ c

23 = 0.95(20) + c

c = 4

y = 0.95x + 4

Suppose that five ones and four zeros are arranged around a circle. Between any two equal bits you insert a 0 and between any tw

PolarNik [594]

Answer:

Using backward reasoning we want to show that "We can never get nine 0's".

Step-by-step explanation:

Basically in order to create nine 0's, the previous step had to have all 0's or all 1's. There is no other way possible, because between any two equal bits you insert a 0.

If we consider two cases for the second-to-last step:

There were 9 0's:

We obtain nine 0's if all bits in the previous step were the same, thus all bit were 0's or all bits were 1's. If the previous step contained all 0's, then we have the same case as the current iteration step. Since initially the circle did not contain only 0's, the circle had to contain something else than only 0's at some point and thus there exists a point where the circle contained only 1's.

There were 9 1's:

A circle contains only 1's, if every pair of the consecutive nine digits is different. However this is impossible, because there are five 1's and four 0's (we have an odd number of bits!), thus if the 1's and 0's alternate, then we obtain that 1's that will be next to each other (which would result in a 1 in the next step). Thus, we obtained a contradiction and thus assumption that the circle contains nine 0's after iteratins the procedure is false. This then means that you can never get nine 0's.

To summarize, in order to create nine 0's, the previous step had to have all 0's or al 1's. As we didn't start the arrange with all 0's, the only way is having all 1's, but having all 1's will not be possible in our case since we have an odd number of bits.

What is the constant of proportionality in the graph below? (answer must be simplified fraction) PLEASE HELP I WILL MAKE U BRAIN

Pepsi [2]

Answer:

The constant of proportionality is $\frac{9}{2}$

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities

If x and y are in directly proportion, then $\frac{y}{x}=k$ , where k is the constant of proportionality.

The direct proportion can be represented by a line whose equation is y = kx, where k is the slope of the line.

To find the constant of proportionality from the given graph choose a point on the line and substitute x and y in the equation of the proportionality by the coordinates of the point.

∵ Point (4, 18) lies on the line

∴ x = 4, y = 18

∵ The equation is y = kx

→ Substitute x by 4 and y by 18

∴ 18 = k(4)

∴ 18 = 4k

→ Divide both sides by 4 to find k

∴ $\frac{18}{4}=\frac{4k}{4}$

∴ $\frac{18}{4}=k$

→ Simplify the fraction by dividing up and down by 2

∴ $\frac{9}{2}=k$

∴ The constant of proportionality is $\frac{9}{2}$

Answer: height is 7 inches

Step-by-step explanation:

height=2 ×Area/Base

= 2 (150.5/43)

=2 (3.5)

h = 7
