Which parabola will have one real solution with the line y=x-5?

His tuition was increased by 10.34%

A quantity or ratio stated as a fraction of 100 is known as a % in mathematics (from the Latin per centum, "by a hundred").

The Latin word per centum, which means "hundred" or "by the hundred," is the source of the word "percent." The Italian phrase per cento, which means "for a hundred," gradually shrank to become the symbol for "percent," which is now used globally. It finally vanished totally. The word "per" was frequently shortened to "p." Two circles and a horizontal line made up the "cento," which is how the contemporary "%" symbol is now represented.

Given, Larry's tuition for last semester was $5510

% increase= (6080-5510)/5510

=0.10344

=0.10344*100

=10.34%

The equation of line passing through points (4,−2) and (8, 3) is 4y - 5x + 28 = 0

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

Given pair of points are  (4,−2) and (8, 3).

The equation of line passing through two points (x₁, y₁) and (x₂, y₂) is given as,

y = ((x - x₁) / (x₁ - x₂)) (y₁ - y₂) + y₁

Substitute the respective values to get the equation of line as,

y = ((x - 4 ) / (4 - 8)) (-2 - 3) + (-2)

y = ((x - 4 ) / 4) × 5 - 2

4(y + 2) = 5(x - 4)

4y - 5x + 28 = 0

Hence, the equation of line for the given points is 4y - 5x + 28 = 0.

A)  the domain is:

D: [0, 6]

The range is:

B)  

"The slope is __1/2__ So, the water amount in the rain barrel changes at a rate of __1/2__ inch per day."

"The Y-intercept is __2__ So, the amount of water in the rain barrel before the rain began was __2__ inches."

And the graph can be seen at the end.

Here we have the linear equation:

d(t) = (1/2)*t + 2

This refers to the amount of water in a barrel for six rainy days, where t is the number of days.

So the domain goes between t = 0 and t = 6.

The range will go between:

d(0) = (1/2)*0 + 2 = 2

d(6) = (1/2)*6 + 2 = 3 + 2 = 5

So the domain is:

D: [0, 6]

The range is:

T: [2, 5]

b) The complete sentences are:

"The slope is __1/2__ So, the water amount in the rain barrel changes at a rate of __1/2__ inch per day."

"The Y-intercept is __2__ So, the amount of water in the rain barrel before the rain began was __2__ inches."

The number of cupcakes sold will be 4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that, in the first hour, Brady sold 1/3 cupcakes and Jaquan sold 3/8 cupcakes. During the second hour, they sold 2 cupcakes. During the third hour, they sold 75% of the remaining cupcakes. During the fourth hour, they sold the remaining 3 cupcakes.

The number of cupcakes sold will be,

N = (1/3) + (3/8) +[(2-1/3-3/8)]+3

N = (1/3)+(3/8) + (7/24)

N = 96 / 24

Answer: f (x)= -2x + 4

Answer:

12 ft, 13 ft , 17 ft

Step-by-step explanation:

let x be the length of the second side , then

one side is x + 1

third side is x + 5

the perimeter P is the sum of the 3 sides, then

P = x + x + 1 + x + 5 ← collect like terms

P = 3x + 6

given P = 42 , then equating gives

3x + 6 = 42 ( subtract 6 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

x + 1 = 12 + 1 = 13

x + 5 = 12 + 5 = 17

the 3 sides are 12 ft, 13 ft , 17 ft

By using the concept of growth, it can be calculated that

Value of coin in 8 years is $3.52

[tex]3(\frac{51}{50})^x[/tex] is the required exponential function

Domain of the function is all positive real number

Range is [tex](0, \infty)[/tex]

y- intercept is 3

This means initial value of the coin is $3

What is growth?

Growth is the exponential increase in the value of the product at a certain rate over a certain period of time

Here, concept of growth has been used

Present value of the coin = $3

Rate = 2%

Time = 8 years

Future value =

[tex]3(1 + \frac{2}{100})^8\\\\3(1 + \frac{1}{50})^8 \\\\3(\frac{51}{50})^8[/tex]

= $3.52

If the time is x years, the given exponential function is

y =

[tex]3(1 + \frac{1}{50})^x\\\\3(\frac{51}{50})^x[/tex]

This is the required exponential function.

Since x represents time here, then x has to be positive

Domain of the function is all positive real number

Now

As  [tex]x\rightarrow \infty[/tex], [tex]f(x) \rightarrow \infty[/tex]

As  [tex]x\rightarrow -\infty[/tex], [tex]f(x) \rightarrow 0[/tex]

Range is [tex](0, \infty)[/tex]

For y- intercept, x = 0

Putting x = 0, we get y = 3

y- intercept is 3

This means initial value of the coin is $3

A solution to this inequality |y + 4| < 1 in as an interval is: A. −5 < y < –3.

An inequality simply refers to a mathematical relation that can be used to compare two (2) or more numerical values, numbers, and variables in an algebraic equation, especially based on any of the following inequality symbols:

Adding -1 to both sides of the inequality, we have:

|y + 4| + (-1) < 1 + (-1)

|y + 4| - 1 < 0

Evaluating the absolute value function, we have the following:

y + 4 < ±1

For the positive interval, we have:

y < -4 + 1

y < -3

For the negative interval, we have:

y < -4 - 1

The calculation of the ending inventory and the cost of goods sold using FIFO and LIFO methods for ABC Inc. is as follows:

                                          FIFO          LIFO

Ending inventory          $10,250     $12,800

Cost of goods sold       $17,000     $14,450

FIFO, which means First-in, First-out, computes the cost of goods sold based on the assumption that the physical flow of goods sold depends on the earlier inventory in stock.

FIFO can be applied under both the perpetual and periodic inventory systems, unlike LIFO.

LIFO means Last-in, First-out, and as a cost flow assumption assigns the cost of goods sold based on the latest inventory purchases.

LIFO cannot be used under the perpetual inventory system.

Date        Activities                       Units     Unit Rate      Total Cost

April 1     Beginning inventory       220          $50             $11,000

April 5    Purchases                        100          $60                6,000

April 10   Purchases                         50          $45                2,250

April 16   Sales                              -300          $80

April 25  Sales                                -20          $95

Units sold                                      320

Ending inventory                         250

FIFO:

Ending Inventory = $10,250 (200 x $40 + 50 x $45)

Cost of goods sold = $17,000 ($27,250 - $10,250)

LIFO:

Ending Inventory = $12,800 (220 x $50 + 30 x $60)

Given,

Ellipse given,

x²+ xy + y ² = 7

Differentiating:

dy/dx

x²+ xy + y² = 7

d/dx(x² + xy + y²) = d/dx(7)

2x + 1y + x dy/dx + 2y dy/dx = 0

dy/dx = 2x + y/ x + 2y

dy/dx = 0

2x + y = 0

x + 2y = 0

Now, we have 2 equations,
