−100D, left parenthesis, x, right parenthesis, equals, start fraction, 1, divided by, 36, end fraction, left parenthesis, x, minus, 60, right parenthesis, squared, minus, 100
What is the lowest altitude Ying will reach?

Answers

Answer 1

Answer:

The lowest point is -100 meters, or 100 meters down

Step-by-step explanation:

D(x)=1/36(x-60)^2-100

This equation is in vertex form

y = a(x-h)^2 +k  where (h,k) is the vertex

Since a is positive, the parabola opens up

The vertex is the minimum, which means it will be the lowest point

The vertex is (60,-100)

The lowest point is -100 meters, or 100 meters down

Answer 2

Given expression

y=1/36(x-60)²-100

Compare to the vertex form

y=a(x-h)²+k

We get

.

a=1/36(h,k)=vertex=(60,-100)

As a is positive parabola is opening upwards and vertex is minimum

Lowest altitude is -100m

Eduardo has in his pocket $1 in pennies, $1 in nickels, and $1 in dimes. If he randomly pulls out just one coin, what is the probability that he will pull out a dime?

Answers

The probability of picking a dime from the coins in his pocket is 1/13

1 penny = 1 cent

Hence, 100 pennies = $1

1 nickel = 5 cent

20 nickels = $1

1 dime = 10 cent

10 dime = $1

This means that :

Eduardo has :

100 pennies 100 pennies 20 nickels 100 pennies 20 nickels 10 dimes

Total coins = (100 + 20 + 10) = 130 coins

Recall :

Probability = required outcome / Total possible outcomes

P(dime) = number of dimes / total coins

P(dime) = 10 / 130 = 1/13

Hence, the probability of picking a dime = 1/13

Answers

Answer:

A. (10, -8)

Step-by-step explanation:

Given function:

f(x) = (x - 10)² - 8

The vertex form of a quadratic function:

f(x) = (x - h)² + k, where (h, k) is the vertex

According to the above, the vertex of the given function is:

(10, -8)

Correct choice is A

Step-by-step explanation:

y=(x-10)²-8

General equation of parabola

vertex form is given by

y=a(x-h)²+k

On comparing we get

h=10k=-8

So vertex is at (10,-8)

Members of a lacrosse team raised $1814.75 to go to a tournament. They
rented a bus for $1168.50 and budgeted $58.75 per player for meals. Which
equation could be used to determine 2, the number of players the team can
bring to the tournament?

Answers

Answer: Choice B

x = (1814.75 - 1168.50)/(58.75)

==============================================

Explanation:

x = number of players

58.75x = cost of all the meals for those x players

58.75x + 1168.50 = adding on the cost of the bus

58.75x + 1168.50 = 1814.75

----------

Let's solve for x.

58.75x + 1168.50 = 1814.75

58.75x = 1814.75 - 1168.50

x = (1814.75 - 1168.50)/(58.75)

x = 11

This means 11 players can go on the trip.

1 player = $58.75 in meals

11 players = 11*58.75 = $646.25 total in meal costs

646.25 +  1168.50 = 1814.75

So this confirms the answer.

The correct equation to determine the number of players (x) the team can bring to the tournament is x = (1814.75 - 1168.5) / 58.75.So, the correct answer is B. x = (1814.75-1168.5)/58.75

The amount raised by the lacrosse team is $1814.75. They spent $1168.50 on the bus rental and budgeted $58.75 per player for meals. Let's break down the expenses:

Total expenses = Bus rental cost + (Number of players * Meal cost per player)

Total expenses = $1168.50 + (x * $58.75)

The equation that represents the total expenses in terms of the number of players (x) is: Total expenses = $1168.50 + $58.75x

Since the team raised $1814.75, we can set up the equation:

Total expenses = Amount raised

$1168.50 + $58.75x = $1814.75

Now, let's solve for x:

$58.75x = $1814.75 - $1168.50

$58.75x = $646.25

Dividing both sides by $58.75:

x = $646.25 / $58.75

x = 11

So, the correct equation to determine the number of players (x) the team can bring to the tournament is: B. x = (1814.75 - 1168.5) / 58.75

a) y = [tex]\frac{1}{2} x[/tex]

b) y = [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

I. If y = 9 and x = 18

  so x is double value of y or y * 2

  y will be half of x value

 that makes y = [tex]\frac{1}{2}[/tex] x

II. If x = 5, replace x with 5

    y = [tex]\frac{1}{2}[/tex] (5)

    y = [tex]\frac{5}{2}[/tex]

What is the sum of 5 numbers whose average is 5 more than 5?

Answers

Answer:

The sum of 5 numbers with an average of 5 more than 5 is 50

Step-by-step explanation:

Let the first five letters of the alphabet be equal to the 5 numbers being summed.

Let the average be represented by the following equation:

[tex]\frac{a + b + c + d + e}{5} = 10[/tex]

To find the sum, we should get rid of the denominator. To do that we multiply 5 on both sides

[tex]\frac{a + b + c + d + e}{5} (5) = 10(5)\\a + b + c + d + e = 50[/tex]

Therefore, we see to it that the sum of the 5 numbers is 50.
