- b. Yolanda played a new number game with Xavier. She used this equation to generate her response to each number Xavier said: y

= x - 2 Describe with words the rule Yolanda uses. Then make a function table a that shows the numbers Yolanda says for four numbers Xavier might say. Use 0 for one of Xavier's numbers and three more numbers of your choosing. Is the function linear? Is it proportional?​

Answer:

Table is below in explantation

Not proportional

yes, linear

Step-by-step explanation:

We substitute and solve:

TABLE:

X --> Y

0 --> -2 (0-2 = -2)

1 --> -1

2 --> 0

Yes, it is linear, the slope is 1 and is written in slope - intercept form

No, not proportional, the y - intercept is (0, -2) not (0,0)

(a) One possibility is 8.45

Rounded to the nearest integer = 8

Rounded to the nearest tenth = 8.5

And rounding this to the nearest integer = 9

 

(b) The possible numbers are 8.45 to 8.49, inclusively

RS = \sqrt{(b-0)^{2}+(c-a)^{2}} and RS is simplified to RS = \sqrt{a^{2}+b^{2}+c^{2}-2ac}

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

We know that , Distance between any two points (x_1 , y_1) and (x_2, y_2) is given by formula :

Distance = \sqrt{(x_1-x_2)^{2}+(y_1-y_2)^{2}}

In this question , we have R(0,a) and S(b,c) .

We need to simplify RS which is given by:

Distance = \sqrt{(x_1-x_2)^{2}+(y_1-y_2)^{2}}

⇒ Distance = \sqrt{(x_1-x_2)^{2}+(y_1-y_2)^{2}}

⇒ RS = \sqrt{(x_1-x_2)^{2}+(y_1-y_2)^{2}}

⇒ RS = \sqrt{(0-b)^{2}+(a-c)^{2}}

⇒ RS = \sqrt{(b-0)^{2}+(c-a)^{2}}

We know that , (a-b)^{2} = a^{2}+b^{2}-2ab

⇒ RS = \sqrt{b^{2}+c^{2}+a^{2}-2ac}

⇒ RS = \sqrt{a^{2}+b^{2}+c^{2}-2ac}

∴ RS = \sqrt{(b-0)^{2}+(c-a)^{2}} and RS is simplified to RS = \sqrt{a^{2}+b^{2}+c^{2}-2ac}.

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 3427 feet and Plane B is at an altitude
jeyben [28]
3427 + 65.75s = 5000 + 35.5s
65.75s - 35.5s = 5000 - 3427
30.25s = 1573
s = 1573 / 30.25
s = 52 seconds <== they are the same at 52 seconds

3427 + 65.75(52) = 6846
5000 + 35.5(52) = 6846

and their altitude is 6846 <===
