Use a calculator to find the equation which models the exponential data given by the table. ( the x is an exponent btw)
A y = 1.5(3)x
B y = 3(1.5)x
C y = 3(0.5)x
D y = 0.5(3)x

Answers

Answer 1
A) y = 1.5(3)^x

If we plug in x = 0, we get:

y = 1.5(3)^0 = 1.5

However, from the table we can see that when x = 0, y = 2. Therefore, option A is not correct.

B) y = 3(1.5)^x

If we plug in x = 1, we get:

y = 3(1.5)^1 = 4.5

This matches the second value in the table. Let's check the other values:

- When x = 0, y = 3 (matches the first value)
- When x = 2, y = 6.75 (matches the third value)

Therefore, option B is correct.

C) y = 3(0.5)^x

If we plug in x = 0, we get:

y = 3(0.5)^0 = 3

However, from the table we can see that when x = 0, y = 2. Therefore, option C is not correct.

D) y = 0.5(3)^x

If we plug in x = 1, we get:

y = 0.5(3)^1 = 1.5

This does not match the second value in the table. Therefore, option D is not correct.

Therefore, the correct equation that models the exponential data given by the table is:

y = 3(1.5)^x.

Ron eats 3 times as many chocolate bars as Bob. Bob ate 5 more chocolate bars than billy. Billy had 1/2 as many as Betty and Betty ate 10 chocolate bars. How many chocolate bars did Ron eat

Answers

Number of chocolate bars that Ron eat is 30

To solve the problem, we can work backwards from the information provided and use variables to represent unknown quantities.

Let's start with Betty, who ate 10 chocolate bars. We know that Billy had half as many as Betty, so we can represent Billy's chocolate bars as:

Billy = 1/2 × Betty

Billy = 1/2 × 10

Billy = 5

Next, we know that Bob ate 5 more chocolate bars than Billy, so we can represent Bob's chocolate bars as:

Bob = Billy + 5

Bob = 5 + 5

Bob = 10

Finally, we know that Ron eats 3 times as many chocolate bars as Bob, so we can represent Ron's chocolate bars as:

Ron = 3 × Bob

Ron = 3 × 10

Ron = 30

Answer:y=_____.

Answers

y = (x - 1)² - 1

y = (x + 13)² - 9.

The given equation is y = x² - 2x. To put the equation in the form y = (x - h)² + k, we will complete the square as follows:Step 1: First, we need to find the value of h by dividing the coefficient of x by 2 and squaring the result. This value will be added inside the parenthesis to complete the square. So, h = (-2/2)² = 1.Step 2: Now, we will add and subtract the value of h inside the parenthesis. y = x² - 2x + 1 - 1 = (x - 1)² - 1Step 3: Finally, we need to find the value of k by subtracting the constant term outside the parenthesis. So, k = -1. Therefore, the equation y = x² - 2x can be written in the form y = (x - 1)² - 1. Answer: y = (x - 1)² - 1.The given equation is y = x² + 26x + 160.

Answers

The cylinder has a volume of about 30.55 cubic feet. Consequently, option D, which is 30.55 cubic feet, is the right response.

How do you calculate a cylinder's volume?

As a result, the product of the base area and height can be used to determine the cylinder's volume. The volume of any cylinder with base radius "r" and height "h" equals base times height. A cylinder's volume is therefore equal to r²h cubic units.

We use the following formula to determine a cylinder's volume:

V = πr²h

The height of the cylinder is 3.8 feet, according to the issue description.

The distance in feet between two points on the circular base that pass through the centre is designated as the 3.2 feet segment.

When these values are added to the formula, we obtain:

V = π(1.6)²(3.8)

To solve the following trigonometric equations, follow the steps given below:sec x + 1 = tan xcos x = sin x - 12π is the solution to the trigonometric equation sec x + 1 = tan x on the interval [0, 2π]. Let's try to solve the given equation:sec x + 1 = tan xLet's use the identity for secant and tangent in terms of cosine and sine:sec x = 1/cos xtan x = sin x / cos xSubstitute these into the given equation:1/cos x + 1 = sin x / cos xThe denominator of the right-hand side can be cleared by multiplying both sides by cos x.

To make a scatter plot of the data from each table, begin by assigning the x-axis to represent the values from one of the tables and the y-axis to represent the values from the other table. Then plot each pair of values onto the graph, creating a "scatter" of points. To draw a trend line, look for the general pattern in the data points and draw a line that best fits them. To find the equation of the trend line, use the formula y = mx + b, where m is the slope of the line and b is the y-intercept. To find the slope of the line, use the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are any two points on the line. To find the y-intercept, plug the slope and any point on the line into the equation y = mx + b and solve for b.

The given data is as follows: 5, 66, and 9. We can plot these values in a scatter plot by following the steps mentioned below:Step 1: Plot the given data points on the Cartesian plane. Step 2: Find the equation of the line of best fit/trend line. We can use the least-squares regression method to find the line of best fit/trend line. This method gives us the equation of a line that best represents the relationship between two variables. In this case, the two variables are X and Y. Step 3: Draw the trend line on the scatter plot. Step 4: Write the equation of the trend line. The equation of the line of best fit/trend line is in the form of y = mx + c, where m is the slope of the line, and c is the y-intercept. . However, we can still draw a line of best fit/trend line that passes through the data points. The equation of the line of best fit/trend line can be found using the least-squares regression method. Using this method, we get the equation of the line of best fit/trend line as: y = -10.33x + 71.33Therefore, the equation of the trend line is y = -10.33x + 71.33.

The upon an electron at point B can be calculated using the formula F = qE, where F is the force, q is the charge of the electron, and E is the electric field magnitude. The charge of an electron is 1.6 x 10^-19 C, and the electric field magnitude at point B is 0.51 V/m. Therefore, the magnitude of the electric force is:

F = (1.6 x 10^-19 C) (0.51 V/m) = 8.16 x 10^-20 N

To determine the direction in which the electron would accelerate at point B, we need to consider the direction of the electric field. The electric field direction at point B is not given in the table, but we can assume that it is the same as the direction at point A, which is 7.

Therefore, the electron would accelerate in the direction opposite to the electric field, or -7.

The vector indicating the direction in which the electron would accelerate at point B can be drawn as follows:

A ball is thrown straight down from the top of a 482-foot building with an initial velocity of -19 feet per second. Use the position function below for free-falling objects. s(t) = -16t^2 + v0t + S0 What is its velocity after 2 seconds?

Answers

The velocity of the ball after 2 seconds is 412 feet per second.

The position function for free-falling objects is s(t) = -16t^2 + v0t + S0, where t is the time, v0 is the initial velocity, and S0 is the initial position. In this case, the initial velocity v0 is -19 feet per second and the initial position S0 is the top of a 482-foot building.

To find the velocity after 2 seconds, we can plug in the time t = 2 into the equation and solve for the velocity v:

s(t) = -16t^2 + v0t + S0

s(2) = -16(2)^2 + (-19)(2) + 482

s(2) = -32 -38 + 482

s(2) = 412

Therefore, the velocity of the ball after 2 seconds, after calculation, is 412 feet per second.

[tex]\mathcal{P}_{2} = \dfrac{37.8(15)}{6} \implies \bf \mathcal{P}_{2} = 94,5 \ inches\\[/tex]

Two triangles are similar. The perimeter of the larger triangle is 94.5 inches.

SOLUTION:

Given, Two triangles are similar.  

The height of the smaller triangle is 6 inches and the corresponding height of the larger triangle is 15 inches.  

The perimeter of the smaller triangle is 37.8 inches.

We have to find what is the perimeter of the larger triangle?

We know that, for similar triangles, ratio of heights = ratio of perimeters.

[tex]\sf{Then,} \ \frac{height\ of \ 1st \ triangle}{height\ of \ 1st \ triangle} = \frac{perimeter \ of \ 2nd \ triangle}{perimeter \ of \ 2nd \ triangle}[/tex]

[tex]\sf{\frac{6}{15} =\frac{37.8}{perimeter\ of \ 2nd \ triangle}[/tex]

[tex]\sf{Perimeter} \ of \ 2^{nd \ triangle} \ \times6=37.8\times15[/tex]

[tex]\sf{Perimeter} \ of \ 2^{nd \ triangle} =37.8\times\frac{15}{6}=37.8\times\frac{5}{2} =\frac{189}{2} =94.5[/tex]

fsA metal sculpture has a total volume of 1250 cm³ and a mass of 7.9 kg. Work out its density, in grams per cubic centimetre (g/cm³). Give your answer to 2 d.p.​

Answers

The density of the metal sculpture is 6.32 grams per cm³

How to find the density?

Density can be defined as the quotient between mass and volume so we can just use the simple formula:

Density = mass/volume

And here we know the two values that we need to use as inputs in the formula above, these values are:

mass = 7.9kg

volume = 1250 cm³

We want the density in grams, then we can rewrite the mass as:

mass = 7.9kg = 7,900 g

Now just take the quotient between the two given quantities, we will get:

Density = 7,900g/1250 cm³ = 6.32 g/cm³

Taylor works after school in a health-food store, where one of the more challenging tasks is to add cranberry juice to apple juice to make a cranapple drink. A liter of apple juice costs $0.85 and a liter of cranberry juice costs $1.25. The mixture is to be sold for exactly the cost of the ingredients, at $1.09 per liter. How many liters of each juice should Taylor
use to make 20 liters of the cranapple mixture?

Answers

To make 20 litres of the cranapple mixture, Taylor should combine 8 litres of apple juice and (20 - 8) = 12 litres of cranberry juice.

Let's assume that Taylor mixes x liters of apple juice and (20 - x) liters of cranberry juice to make 20 liters of the cranapple mixture.

The price of the used apple juice is $0.85 and the price of the used cranberry juice is $1.25 (20 - x).

The mixture is supposed to be sold for exactly what the ingredients cost, or $1.09 per litre, according to the problem. As a result, the total cost of the juice used to create the mixture must be equivalent to the price at which it is sold.

[tex]0.85x + 1.25(20 - x) = 1.09(20)[/tex]

[tex]0.85x + 25 - 1.25x = 21.8-0.4x = -3.2x = 8[/tex]

Simone built the same number of toy
cars and toy airplanes.
Show how Simone could have built
14 toys. Explain how you know.

Answers

Simone built 7 toy cars and 7 toy airplanes to make a total of 14 toys.

How to solve

Simone could have built 7 toy cars and 7 toy airplanes to make a total of 14 toys.

To confirm this, we can add the number of toy cars and toy airplanes:

7 toy cars + 7 toy airplanes = 14 toys

Since Simone built the same number of toy cars and toy airplanes, dividing 14 by 2 would also give us the number of each type of toy:

14 toys ÷ 2 = 7 toys each (7 toy cars and 7 toy airplanes)

Therefore, we can conclude that Simone built 7 toy cars and 7 toy airplanes to make a total of 14 toys.

show that the points A(3,4),B(7,8),C(11,4) are the vertices of an isosceles triangle (distance)​

Answers

The points are vertices of an isosceles triangle by using distance formula.

What is distance formula?

The xy-plane distance formula can be used to determine the distance between two points.

We know that the distance formula is

d = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

Using this, we get

⇒AB = [tex]\sqrt{(7 -3)^{2} +(8 -4 )^{2} }[/tex]

⇒AB = [tex]\sqrt{(4)^{2} +(4 )^{2} }[/tex]

⇒AB = √16 + 16

⇒AB = √32

Similarly,

⇒AC = [tex]\sqrt{(11 -3)^{2} +(4 -4 )^{2} }[/tex]

⇒AC = [tex]\sqrt{(8)^{2} +(0 )^{2} }[/tex]

⇒AC = √64

⇒AC = 8

Similarly,

⇒BC = [tex]\sqrt{(11 -7)^{2} +(4 -8 )^{2} }[/tex]

⇒BC = [tex]\sqrt{(4)^{2} +(4 )^{2} }[/tex]

⇒BC = √16 + 16

⇒BC = √32

Since. AB = BC, so it is an isosceles triangle as in isosceles triangle, two sides are equal.

Hence, the given points are the vertices of an isosceles triangle.

how many tiles, each measuring 2m by 1m arc required to cover a rectangular hall 12m and 8m broad?​

Answers

Answer:

48 tiles are required.

Step-by-step explanation:

What is the area?

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

To solve for the area of a rectangle, we use this expression:

(Let l = length, w = width and a = area)

l × w = a

Inserting the dimensions of the hall:

12m × 8m = 96 meters squared

Each tile has an area of:

2m × 1m = 2 meters squared

To find the number of tiles needed to cover the hall, we can divide the area of the hall by the area of each tile:

96 ÷ 2 = 48

Therefore, 48 tiles are required to cover the rectangular hall.

The value of the segment MN is 18 units

What are similar triangles?

Similar triangles are triangles that have the same shape but possibly different sizes in proportions

How to determine the value of MN

From the question, we have the following parameters that can be used in our computation:

AB=24 , AD=14 , and MQ=10.5

Given that the triangles are similar, we have the following ratio

AB : AD = MN : MQ

Substitute the known values in the above equation, so, we have the following representation

24 : 14 = MN : 10.5

Make MN the subject

MN = 10.5 * 24/14
