Micah and Linda are 230 feet apart when they start walking toward one another. Linda walks twice as fast as Micah so whenever Mi

BigorU [14]

Answer:

D(x) = 3x

Step-by-step explanation:

Micah travels at a rate of 'x' feet over a specific period.

Linda travels at a rate of '2x' feet over that same period.

Since they are walking in opposite directions, the total distance they have walked towards one another (D) can be determined by adding both distances:

$D(x) = x+2x\\D(x) = 3x$

The expression that describes the number of feet they have walked toward one another is D(x) = 3x.

A pair of dice are rolled. What is the probability of rolling 4 or greater?

skelet666 [1.2K]

Answer: option D: 11/12

Explanation:

1) The sample space is formed by 36 pairs: 6×6 = 36.

2) Roolling 4 or more is the same that not rolling 3 or less

3) Rolling 3 or less are (1,1), (1,2), and (2,1). Those are 3 outcomes out of 36.

4) Therefore, not rolling 3 or less (the same that rolling 4 or more) has 36 - 3 = 33 outcomes out of 36.

5) The probability of 33 out of 36 is 33/36

6) Simplify the fraction 33/36 = 11/12

And that is the answer.

Part B: In complete sentences, explain how a circle can be used to find the circumcenter of the triangle graphed below.

Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

Part B:

The center of the circumscribed circle around a triangle is equidistant from vertices of that triangle. To find the circumcenter need to draw at least two perpendicular bisectors to the sides of the given triangle. Point of intersect of them is center of the circumscribed circle.

Part C:

Coordinates of the midpoint of line BC ( y = - 1 ) are

( $\frac{-6+2}{2}$ , $\frac{-1-1}{2}$ ) = ( - 2 , - 1 ) and the equation of the line ⊥ to BC is x = - 2

Because BC is ║ to x-axis and m∠A is 90° , the center of the circle is midpoint of BC and r = $\frac{BC}{2}$ = 4

PLEASE HEL MUST BE DONE URGENTLY

Y = x + 2 is closest to what I believe is the solution.

If the club begins with 2 members, then +2 MUST appear in the formula.

If the club adds 2 members every week, then the total number of members would be

f(x) = y = 2 + 2(x-1), where x is the number of weeks.

Test this: If x = 1, then y = 2+2(1-1) = 2 + 0 = 2. This is correct. The club began with 2 members in week 1
