The solutions are - 0.8 and 1

Step-by-step explanation:

In the quadratic equation ax² + bx + c = 0

Assume that the solutions of the equations are m and n

∵ 5x² - x - k = 0

- By comparing it by the form above

∴ a = 5, b = -1 , c = -k

- Use the rule of the sum of the two solutions above

∵ The sum of the two solutions = [tex]\frac{-b}{a}[/tex]

∴ The sum of the two solutions = [tex]\frac{-(-1)}{5}=0.2[/tex]

∵ The two solutions are m and n

∴ m + n = 0.2 ⇒ (1)

∵ The difference of the two solutions is 1.8

∴ m - n = 1.8 ⇒ (2)

Now we have a system of equations to solve

Add Equations (1) and (2) to eliminate n

∴ 2m = 2

- Divide both sides by 2

∴ m = 1

- Substitute the value of m in equation (1) to find n

∴ 1 + n = 0.2

- Subtract 1 from both sides

∴ n = -0.8

The solutions are - 0.8 and 1

If you want to find the value of k

∵ The product of the solutions is [tex]\frac{c}{a}[/tex]

∴ The product of the solutions = [tex]\frac{-k}{5}[/tex]

∵ m × n = 1 × (-0.8) = - 0.8

- Equate  [tex]\frac{-k}{5}[/tex]  by - 0.8

∴ [tex]\frac{-k}{5}=-0.8[/tex]

- Multiply both sides by -5

∴ k = 4

∴ The equation is 5x² - x - 4 = 0

Answer:

x = 1; x = -0.8

Step-by-step explanation:

Here is a simpler approach if needed for future students:

5x^2-x-k = 0,

System of Equations: x1 - x2 = 1.8 & x1 + x2 = 1/5 = 0.2 (if x1 and x2 are roots)

Now let's add the two:

x1 - x2 = 1.8

+ x1 + x2 = 0.2

----------------------

2x1 = 2,

x1 = 2/2 = 1

- x2 = 1.8 - 1 = 0.8 => x2 = -0.8

Answer:

Circumcenter O (0.5 , 5)

Step-by-step explanation:

Circumcenter O (x , y)

OA = OB = OC

OA² = (x + 4)² + (y - 3)²

OB² = (x - 5)² + (y - 7)²

OC² = ( x + 4)² + (y - 7)²

OA² = OC² : (x + 4)² + (y - 3)² = ( x + 4)² + (y - 7)²

(y - 3)² = (y - 7)²        y² - 6y + 9 = y² -14y + 49

8y = 40

y = 5

OB² = OC² : (x - 5)² + (y - 7)² = ( x + 4)² + (y - 7)²

x² - 10x + 25 = x² + 8x + 16

18x = 9

x = 0.5

The height of a randomly chosen basketball player is a continuous random variable since height is measured and can take on an infinite range of values.

The random variable described, the height of a randomly chosen basketball player, is a continuous random variable. This is because height can take an infinite number of possible values within a range and is measured rather than counted. Unlike discrete random variables, which have countable values such as the number of heads in a coin toss, continuous random variables like height are measured and can include values such as 6'1" or 6'1.5". The values are on a continuous scale, and therefore the probability distribution of a continuous random variable is concerned with the probability of the variable falling within a certain range, rather than taking specific countable values.

Answer: 72 ft

Step-by-step explanation:

We can solve this problem using geometry, if we draw two righ triangles (figure attached):

-One formed by you, assuming you are 6 ft tall, and the ground

-The other formed by the height  of the cliff, the bottom of the cliff and the ground.

Both triangles are congruent, having the mirror as a common vertex, hence we can use the following relation to find :

[tex]\frac{6 ft}{y}=\frac{5 ft}{60 ft}[/tex]

Isolating :

[tex]y=\frac{(60 ft)(6 ft)}{5 ft}=72 ft[/tex] This is the height of the cliff

The calculated height of the cliff is 72 feet.

To determine the height of the cliff, we use a mirror and the property of the reflection of light. Here are the steps to solve the problem:

height of cliff / 60 feet = 6 feet / 5 feet.

    5. Solve for the height of the cliff:

height of cliff = (6 feet / 5 feet) * 60 feet = 72 feet.

Thus, the height of the cliff is 72 feet.

Answer:

see the explanation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the time in seconds

y ---> the distance in meters

In this problem we have a proportional relationship between the variables x and y

Find the constant of proportionality k

[tex]k=\frac{y}{x}[/tex]

For x=2, y=25 ---> [tex]k=\frac{25}{2}=12.5[/tex]

For x=4, y=50 ---> [tex]k=\frac{50}{4}=12.5[/tex]

For x=6, y=75 ---> [tex]k=\frac{75}{6}=12.5[/tex]

For x=8, y=100 ---> [tex]k=\frac{100}{8}=12.5[/tex]

so

The value of k is [tex]12.5\ \frac{m}{sec}[/tex]

In this problem the value of k or slope represent the speed of the train

The linear equation is equal to

[tex]y=12.5x[/tex]

or

[tex]Distance=12.5Time[/tex]

The depth of sun after 5 minutes is 809.82 feet

Solution:

A submarine dives at an angle of 13 degrees to the surface of the water

The submarine travels at a speed of 720 feet per minute

The figure is attached below

ACB is a right angled triangle

AB is the distance between surafce of water and submarine

BC is the depth of submarine

Let "x" be the depth of sun after 5 minutes

Therefore, distance between submarine and surface of water is:

[tex]AB = 720 \frac{feet}{minute} \times 5 \text{minute} = 3600 feet[/tex]

Submarine dives at an angle of 13 degrees to the surface of the water

Therefore, angle A = 13 degrees

Now we have to find BC

By definition of sine,

[tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]

Here, opposite = BC = x

hypotenuse = AB = 3600 feet

Thus, we get,

[tex]sin \theta = \frac{BC}{AB}\\\\sin \theta = \frac{x}{3600}\\\\sin 13 = \frac{x}{3600}\\\\0.2249 = \frac{x}{3600}\\\\x = 3600 \times 0.2249\\\\x = 809.82[/tex]

Thus the depth of sun after 5 minutes is 809.82 feet

To calculate f(-5) for the function f(x)=-x+2, we substitute -5 in place of x, which gives us f(-5) = 7.

To find the value of f(-5) for the function f(x)=−x+2, we simply substitute x with -5:

f(-5) = −(-5) + 2

Now, we perform the operations:

f(-5) = 5 + 2

f(-5) = 7

Therefore, the answer is 7.

Answer:

Step-by-step explanation:

The store initially bought 82 half gallons of milk.

To solve the problem, we need to find out how many half gallons of milk the store initially bought. We can set up an equation to represent the situation where the cost of milk is subtracted from the sales to find the profit.

Let's assume the store bought x half gallons of milk. Then, the cost of the x half gallons is x multiplied by $2.70:

Cost = 2.70x dollars

The store ruined 12 half gallons, so they can only sell x - 12 half gallons. The revenue from selling each half gallon is $4.02, so the total revenue from selling x - 12 half gallons is:

Revenue = 4.02(x - 12) dollars

We are told the store made a profit of $60, so the revenue minus the cost equals the profit:

4.02(x - 12) - 2.70x = 60

Now we solve for x:

4.02x - 48.24 - 2.70x = 60

1.32x - 48.24 = 60

1.32x = 108.24

x = 82 half gallons

Therefore, the store initially bought 82 half gallons of milk.

To find the average number from a list of numbers, add up all the numbers and then divide the sum by the total number of numbers.

Explanation:

The question asks for the average number from a given list of numbers. To find the average, you add up all the numbers in the list and then divide the sum by the total number of numbers in the list.

In this case, the average of the numbers 1, 0, 1, 5, 6, 3, and 4 can be found by adding those numbers together (1 + 0 + 1 + 5 + 6 + 3 + 4) and then dividing the sum by 7 (the total number of numbers in the list). So, the average is 4.

The system of equation is:

x + y = 20

x - y = 4

She has 12 dimes and 8 nickels

Step-by-step explanation:

The given is:

We need to write a system of equations that represents the problem and how

many of each coin she has

Assume that she has now x dimes and y nickels

∵ She has x dimes and y nickels

∵ She has a total of 20 coins

- Add x and y, then equate the sum by 20

∴ x + y = 20 ⇒ (1)

∵ One dime = 10 cents

∵ One nickels = 5 cents

- Multiply x by 10 and y by 5 to find how many cents she has now

∵ She has now (10x + 5y) cents

∵ The dimes were nickels and the nickels were dimes

- Multiply x by 5 and y by 10 to find how many cents she has

   after the change

∴ She had after the change (5x + 10y) cents

∵ The value after the change is less than the value now by

   20 cents

- Subtract (5x + 10y) from (10x + 5y) and equate the difference

   by 20

∴ (10x + 5y) - (5x + 10y) = 20

- Add the like terms in the left hand side

∴ (10x - 5x) + (5y - 10y) = 20

∴ 5x - 5y = 20

- Divide both sides by 5

∴ x - y = 4 ⇒ (2)

The system of equation is:

x + y = 20

x - y = 4

Now we have a system of equations to solve it

Add equations (1) and (2) to eliminate y

∴ 2x = 24

- Divide both sides by 2

∴ x = 12

- Substitute the value of x in equation (1) to find y

∵ 12 + y = 20

- Subtract 12 from both sides

∴ y = 8

She has 12 dimes and 8 nickels
