40(2.25)ˣ function equation is represented by the graph transformation.

What do graph transformations mean?

Changes to the graph of a parent function are referred to as transformations. Transformations may be divided into three categories: translations, reflections, and dilations. There are two types of transformations that may be done to a function: vertical (which affects the y-values) and horizontal.

                               (affects the x-values). The following guidelines apply to the function translation and transformation: The function is moved up b units by f (x) + b. The function is moved downward by the notation f (x) b. The function is moved left by the value of f (x + b).

Let the function be of the form

  f(X ) = a(b)ˣ

Then the point (0,40) lies on the graph of this function. This point must satisfy the equation of the function.

We substitute the point to get,

  40 = a(b)⁰

This implies that,

   40 = a(1)

    40 = a

We substitute a=40 into the function equation to get,

         f(x) = 40(b)ˣ

The point (1,90) also lies on the graph of the function. This gives us,

       90 = 40(b)¹

       90 = 40b

      b = 90/40

       b = 2.25

We substitute the value of b also into function to get,

    f(X) = 40(2.25)ˣ

46. There are 9 complete doses available from the bottle. 47. There are 8 full doses available in the 120 mL bottle.

Although weight and mass are frequently used interchangeably, they have distinct meanings in the study of physics. Weight is a measurement of the force of gravity acting on an item, whereas mass is a measure of the amount of matter that makes up an object. Weight is typically expressed in newtons (N) or pounds, while mass is typically expressed in kilogrammes (kg) (lb). While an object's mass remains constant, its weight can change depending on how strongly gravity is pulling on it.

46. We know that,

1 fluid ounce = 29.5735 mL

4 fluid ounces = 4 x 29.5735 = 118.294 mL

Each dose is 12.5 mL:

118.294 / 12.5 = 9.46

So there are 9 complete doses available from the bottle.

47. Given, 1 tablespoon is equal to 15 mL.

Thus, doses of 15 mL are in a 120 mL bottle:

120 / 15 = 8

So there are 8 full doses available in the 120 mL bottle.

The probability of choosing a ball numbered 29 is among the 28 balls numbered 1 through 28 is 0

From the question, we are to calculate the probability of choosing a ball numbered 29

From the formula for probability

P(A) = Number of favorable outcomes to A / Total number of possible outcomes

From the given information,

"A lottery game contains 28 balls numbered 1 through 28"

This means there are only 28 balls and they are numbered from 1, 2, 3, up until 28.

Now,

We are to determine the probability of choosing a ball numbered 29. Since there is no ball numbered 29,

Number of favorable outcomes = 0

Total number of possible outcomes = 28

Thus,

Probability of choosing a ball numbered 29 = 0/28

Probability of choosing a ball numbered 29 = 0

Hence,

Probability of choosing a ball numbered 29 is 0

Answer:

√75 =8.66.

Step-by-step explanation:

The square root of 75 is an irrational number where the numbers after the decimal point go up to infinity. √75 = 8.660.√75 cannot be written in the form of p/q, hence it is an irrational number. irrational with never-ending digits.

Let's see how to find the square root of 75 by the long division method.

Step 1: Express 75 as 75.000000. We take the number in pairs from the right. Take 75 as the dividend.

Step 2: Now find a quotient which is the same as the divisor. Multiply quotient and the divisor and subtract the result from 75.

Step 3: Now double the quotient obtained in step 2. Here is 2 × 8 = 16. 160 becomes the new divisor.

Step 4: Apply decimal after quotient '8' and bring down two zeros. We have 1100 as the dividend now.

Step 5: We need to choose a number that while adding to 160 and multiplying the sum with the same number we get a number less than 1100. 160+ 6 = 166 and 166 × 6 = 996. Subtract 996 from 1100. We get 104

Step 6: Bring down two zeros again and place it after 104, so that it becomes 10400 which is the new dividend. Now multiply the number in the quotient by 2. Here it is 86. We get 172. Have it as 1720. Now find a number at the unit's place of 1720 multiplied by itself gives 10400 or less. We find that  1726  × 6 = = 10356. Find the remainder.

Step 7 : Repeat the process until we get the remainder equal to zero. The square root of 75 up to two places is obtained by the long division method. Thus √75 = 8.66

Answer:

1, -9

Step-by-step explanation:

xy = -9

x + y = -8    solve this for x and substitute into the 1st equation

x = -8 - y

(-8 - y)y = -9

-y² - 8y + 9 = 0

y² + 8y -9 = 0

Solve for y by factoring:

(y - 1)(y + 9) = 0

y = 1, -9

x = -9

x(-9) = -9

x = -9/-9 = 1

The solutions to the rational equations are

The rational equations can be solved as follows

(1)

(x - 2)/(2x + 4) = 1/5

This gives

5x - 10 = 2x + 4

So, we have

3x = 14

x = 14/3

(2)

For equation (2), we have

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

So, we have

[2(x + 3) - x]/4 = 4/3

[x + 6]/4 = 4/3

So, we have

3x + 18 = 16

x = -2/3

(3)

For equation (3), we have

3/(x + 1) - 2/(x - 1) = 1/(x² - 1)

So, we have

3(x - 1) - 2(x + 1) = 1

This gives

3x - 3 - 2x - 2 = 1

x = 4

(4)

For equation (4), we have

18/(x² - 3x) = 2x/(x - 3) - 6/x

So, we have

18 = 2x² - 6(x - 3)

This gives

x = 0 or x = 3

(5)

For equation (5), we have

3x/(x + 2) + 6/x + 4 = 12/(x² + 2x)

Multiiply through by x² + 2x

3x² + 6(x + 2) + 4(x² + 2x) = 12

Evaluate

x = 0 or x = -2

(6)

For equation (6), we have

1/(x - 2) + 4/(x + 9) = 3/(x² + 7x - 18)

Multiiply through by (x² + 7x - 18)

x - 9 + 4x + 8 = 3

So, we have

5x = 4

Evaluate

x = 4/5

(7)

For equation (7), we have

3/5x² - 1/5 = 2/25x²

Multiiply through by 25x²

15 - 5x² = 2

So, we have

5x² = 17

Evaluate

x = √(17/5)

(8)

For equation (8), we have

9/(x + 1) = 2/(x² - 1)

Multiiply through by 25x²

9x - 9 = 2

So, we have

9x = 11

Evaluate

x = 11/9

(9)

For equation (9), we have

3/(x³ - 8) = 1/(x - 2)

Cross multiiply

(x³ - 8) = 3(x - 2)

Evaluate

x = -1 and x = 2

(10)

For equation (10), we have

x²/2 - 3x/2 + 1 = 0

Multiiply through by 2

x² - 3x + 2 = 0

They adhere to specific arithmetic laws and can be added, deducted, multiplied, and divided.

given

Assume that x and y are the two positive integers, with x being the greater of the two. Finally, we may convert the provided data into equations:

In order to remove x, we can replace the first equation with the second equation as follows:

[tex](2y-2)^2 + y^2 = 260[/tex]

Adding and subtracting:

[tex]4y^2 - 8y + 4 + y^2 = 260[/tex]

combining comparable phrases

[tex]5y^2 - 8y - 256 = 0[/tex]

Using the quadratic formula, we can solve this quadratic equation:

y = [8 ± sqrt(8^2 - 45(-256))] / (2*5)

y = [8 ± sqrt(3368)] / 10

y ≈ 8.6 or y ≈ -9.4

Y must be 8 because we are seeking for positive integers. The first equation can then be used to determine x:

x = 2y - 2 = 2(8) - 2 = 14

Hence, 8 and 14 are the two positive integers as Y must be 8 because we are seeking for positive integers.

Option D.   [tex]g(x)=5(0.8)^{x}+2[/tex]

Step-by-step explanation:

Main concepts

Concept 1: identifying horizontal asymptote

Concept 2: assuring decreasing exponential function

Concept 1. identifying horizontal asymptote

Any exponential function of the form [tex]y=a*b^x[/tex] has a horizontal asymptote on the x-axis.  A constant (positive or negative) added to the end of the exponential expression will shift the graph of the exponential function up (if positive) or down (if negative) the number of units equal to the magnitude of the number.  Since the original function f(x) has a "+2" at the end, it has been shifted up 2 units.  Thus, we can eliminate answers A and C from feasible answers since they each shift the exponential function up 3 units, not 2.

Concept 2. assuring decreasing exponential function

Exponential functions of the form [tex]y=a*b^x[/tex] increase or decrease based on the value of "b".

Observe that the graph of the function f(x) is decreasing, and the value of b=0.5.

To ensure that g(x) also decreases, the b-value must be between 0 and 1, which eliminates option B.

Option D is the correct answer because the value of "b" is between 0 and 1 (making the graph of the function a decreasing exponential), and the number added at the end is "+2", causing the horizontal asymptote to be at a height of positive 2.

Step-by-step explanation:

Answer:

Step-by-step explanation:

We can use the formula for continuous compounding to determine how long it will take each account to reach $1,800.

For Michael's account, the formula is:

A = P*e^(rt)

where:

A is the amount in the account after t years

P is the principal

r is the annual interest rate

t is the time in years

Plugging in the values given, we get:

1,800 = 1,000*e^(0.0475t)

Taking the natural logarithm of both sides, we get:

ln(1,800/1,000) = 0.0475t

t = ln(1,800/1,000)/0.0475

t ≈ 8.55 years

So it will take approximately 8.55 years for Michael's account to reach $1,800.

Similarly, for Peter's account, the formula is:

A = P*e^(rt)

where:

A is the amount in the account after t years

P is the principal

r is the annual interest rate

t is the time in years

Plugging in the values given, we get:

1,800 = 1,200*e^(0.0425t)

Taking the natural logarithm of both sides, we get:

ln(1,800/1,200) = 0.0425t

t = ln(1,800/1,200)/0.0425

t ≈ 9.03 years

So it will take approximately 9.03 years for Peter's account to reach $1,800.

Therefore, Michael's account will grow to $1,800 first as it will take less time (8.55 years) compared to Peter's account (9.03 years).

The percentage increase in the number of water bottles the company manufactured from February to April is 19%.

In March, the company manufactured 7% more water bottles than in February:

Number of water bottles in March = 4,100 + 7% of 4,100

Number of water bottles in March = 4,387

In April, the company manufactured 500 more water bottles than in March:

Number of water bottles in April = 4,387 + 500

Number of water bottles in April = 4,887

To find the percent increase from February to April, we can use the following formula:

percent increase = (new value - old value) / old value x 100%

percent increase = (4,887 - 4,100) / 4,100 * 100%
