Nathan is trying out to be the kicker on his high school's football team. He notices that for every hour he practices he can kick the ball 2 yards further. On his first try he kicked the ball 42 feet, on the second try he kicked the ball 16 yards. What could be a possible distance for his third kick? A. 20 feet B. 60 feet C. 54 yards D. 24 yards

Answers

This is actually a very easy problem. The only hurdle we have here is the units that are used in this problem. We have to understand that each unit may mean the same length but the values are different. In this case, 1 yard is equal to 3 feet. Meaning 42 feet is equal to 16 yards. So that is 14, 16 and the answer is 18 yards. 18 yards is equal to 54 ft.

Rewrite x-2y=3 in slope intercept form

Answers

y = mx + b is the standard slope intercept form
so , x - 2y = 3
add -x on both sides
-2y = -x + 3
dividing -2 on both sides
y = -x/-2 + 3/-2
y = x - 3/2 Ans

The slope intercept form which is y = mx+ c, of the given line is,

y = (1/2)x - 3/2

The best approach to determine without using any geometrical tools if the lines are parallel, perpendicular, or at any angle is to measure the slope.

The slope-intercept form of a line is:

y = mx + c

Where,

m represents the slope of the line

c represents the y-intercept of the line

The given equation of a line is:

x-2y=3

Subtract x both sides,

-2y = -x + 3

Divide both sides of the equation by -2,

y = (1/2)x - 3/2

This is of the form y = mx + c

Slope: m = 1/2

Y-intercept: c = -3/2

Hence,

The slope intercept of the line is y = (1/2)x - 3/2.

Six more than fives times a number (x) is at least 21. I need an inequality.

Answers

5n + 6 ≥ 21 would be the way to write this in math language.

It says that 5n + 6 is 21 or is more than 21. The symbol ≥ says 21 or more in this case.

cornerstone baker sold 78 pies on monday 96 pies tuesday 104 pies wednesday 40 pies thursday 77 pies friday on average how many pies did they sell per day

Answers

To find the average per day use this equation;

total number of pies ÷ total number of days = average of pies per day

78 + 96 + 104 + 40 + 77 = 395

Monday + Tuesday + Wednesday + Thursday + Friday = 5 days...

395 ÷ 5 = 79

so the average of pies sold per day is : 79 pies per day.

. Let A = (−2, 4) and B = (7, 6). Find the point P on the line y = 2 that makes the total distance AP + BP as small as possible.

Answers

Answer:

P(1,2)

Step-by-step explanation:

There are 2 points.

A(-2,4) and B(7,6)

the point P on the y=2 can also represented as P(x,2)

We can use the distance formula to find the distances AP and BP

$\text{dist} = √((x_1 - x_2)^2 + (y_1 - y_2)^2)$

for AP: A(-2,4) and P(x,2)

$AP = √((-2 - x)^2 + (4 - 2)^2)$

$AP = √((-2 - x)^2 + 4)$

$AP = √((-1)^2(2 + x)^2 + 4)$

$AP = √((2 + x)^2 + 4)$

for BP: B(7,6) and P(x,2)

$BP = √((7 - x)^2 + (6 - 2)^2)$

$BP = √((7 - x)^2 + 16)$

the total distance AP + BP will be

$√((2 + x)^2 + 4)+√((7 - x)^2 + 16)$ (plot is given below)

Our task is to find the value of x such that the above expression is small as possible. (we can find this either through plotting or differentiating)

If you plot the above equation, the minimum point of the curve will be clearly visible, and it will be at x = 1. Hence, the point P(1,2) is such that the total distance AP + BP is as small as possible.

Final answer:

The point P that makes the total distance AP + BP smallest on the line y=2 is given by the x-coordinate of the midpoint of A and B because the shortest distance is in a straight line. Therefore, the point P is (2.5, 2).

Explanation:

To find the point P on the line y = 2 that makes the total distance AP + BP the smallest, you need to recall that the shortest distance between two points is a straight line. So, ideally, we want to find a point P (x,2) that is on the same vertical line (or x-coordinate) that intersects the line AB at the midpoint.

Step 1: Find the midpoint of A and B. The midpoint M is obtained by averaging the x and y coordinates of A and B: M = ((-2+7)/2 , (4+6)/2) = (2.5, 5).

Step 2: Since line y = 2 is horizontal, the x-coordinate of our point P will stay the same with the midpoint x-coordinate. Therefore, P has coordinates (2.5, 2).

So, the point on the line y = 2 that makes the total distance AP + BP as small as possible is P (2.5, 2).
